The heating system of a residential building or industrial premises is not just a set of pipes, a radiator and a heating boiler Any heating system must be carefully designed, and its installation will require a lot of effort But the most important thing here is the correct installation of components called fittings for heating systems These are all the elements that control the heating system

 Requirements for the material for manufacturing shut-off valves

 Initially, you need to determine which functions are intended for this or that valve for heating systems In General, its purpose is to control the volume of heat, as well as control the flow of heat carrier

 Based on the design features, all fittings are divided into 2 types – shut-off and control Each of these types performs a specific function and affects the heating system

 Stop valve

 The main purpose of stop valves is to reduce or stop the movement of the heat carrier Usually, various types of taps and plugs installed near radiators are used as shut-off valves Any shut-off valve must have certain characteristics In particular, it must withstand the maximum water temperature (usually 100 degrees), as well as the maximum pressure These holding parameters must be specified in the technical documentation of the valve (technical data sheet)

 Control valve

 If the main purpose of shut-off valves is to stop the flow of heat, the control valves are designed to ensure that all processes taking place in the heating system are implemented as safely as possible In particular, with the help of control valves, the optimal pressure of the coolant is provided, as well as the possibility of mixing cold and hot streams This is necessary in order to be able to adjust the temperature inside the coolant There are control valves for both manual and automatic control The second type is also called electronic fittings

 Regarding the metal from which the fittings are made, most often brass, cast iron or bronze is used as such a metal Sometimes you can find the opinion that the rebar is made of steel However, there are not many such models, since steel is one of the worst materials that interact with hot water without accompanying chemical reactions

 Heating shut-off valves

 The shut-off valves are mainly designed to contain the water flow inside the heating system Such fittings are available in almost every system where it is necessary to reduce or limit the possible flow of coolant

 All the manufacturers of valves (including the company Alastrim) offer their customers a directory of products Thanks to the catalog, you can choose exactly the type of fittings that you need At the same time, so that the choice is correct You need to pay attention to certain parameters, the main ones are:

 - Diameter of the pipe (both input and output) The correct choice of this parameter determines what the flow will be when the tap is fully open In General, the optimal heating system is considered to be one in which the free movement of the coolant is provided when the tap is open

 - Degree of regulation This parameter primarily affects the water pressure in the system It can be adjusted using ball or wedge valves Thanks to the first type, it is possible to quickly optimize the water flow, and with the help of wedges, you can ensure constant water movement in certain parameters

 - The possibility of installing an additional automatic heating control system

 Most often, various types of plugs and taps are used to organize the correct operation of the heating system However, it is important not only to know the basics and goals of their application, but also to select them correctly in order for the system to work normally

 Heating taps

 Taps for heating systems are one of the simplest types of shut-off valves They can be used to optimize the level and pressure of the water flow inside the system Most often, cranes installed near radiators are used At the same time, there are quite a few types of such cranes, each of which has its own characteristics in terms of selection

 Ball valve The design of such a crane is based on a metal ball It is used to regulate the flow of water It is quite simple to operate such a crane – you just need to turn the handle 90 degrees In addition, these cranes are simple in their construction At the same time, they have a certain drawback – with the help of such cranes, it is very difficult to achieve smooth control of the water flow

 Rod cranes The role of the locking element in such cranes is played by a rod consisting of a rubber gasket The main purpose of such cranes is smooth control of water flow In order to set a certain pressure, you need to turn the handle of such a tap for a certain number of revolutions

 When choosing a tap and installing it, special attention should be paid to the operating parameters of the heating system itself Ignoring this rule will lead to the fact that the crane will be selected incorrectly and it will simply be impossible to install it

 In addition, it is necessary to pay attention to the type of gaskets that are used for installing shut-off valves Paronite gaskets are of the highest quality, since they are least susceptible to corrosion and deformation

 Heating valves

 In terms of design features, such elements are similar to rod cranes and work on approximately the same principle A special feature of plugs is that they are used most often in large-diameter heating pipes This is due to the fact that the design of the valve resembles a kind of undulating terrain Due to the high quality of the metal, high pressure is contained, which is observed in large-diameter pipes

 Heating control valves

 The main purpose of control valves is to ensure control and safe operation of the heating system as a whole or in its individual sections There are several types of control valves (including those manufactured by Altstream), each of which has its own characteristics Let's take a closer look at the most famous of them

 Mayevsky Crane

 If the heating radiator has become less heated, it is most likely that an air plug has formed somewhere near it Its appearance can lead to overheating of the water, increase the pressure and eventually lead to failure of the entire heating system To prevent this possibility, it is necessary to install a Mayevsky crane in each system

 This type of valve is made in the form of a needle type valve The upper radiator pipe is selected as the installation location Installation of the Mayevsky crane allows you to quickly eliminate air jams formed inside the heating system In order to get rid of the plug, you need to turn the rod with the help of improvised tools and watch until water starts to flow out of the tap In the process of removing the plug, you will hear the characteristic sound of escaping air

 Check valve

 In order to avoid reverse water movement inside the pipes, it is also necessary to use the appropriate equipment This equipment includes a check valve This device can often be found in control valve catalogs At the same time, such valves can be installed both in small systems for private homes and in industrial heating systems

 The principle of operation of the check valve is based on the fact that under pressure it is opened and pulled back to a certain level If for some reason the water starts to move back, the valve simply returns to its original state Most often this kind of equipment is used in radiators Its use allows you to increase the useful load on the radiator, thereby ensuring the normal operation of the entire heating system

 Mixing units

 If the room has a floor with a water-heated floor, then to ensure its normal functioning, it is necessary to install an element responsible for mixing warm and cold water flow This necessity is explained by the fact that the water temperature in the pipes of the heating system and the floor differs In this case mixing units are used for mixing

 In terms of design mixing units are similar to needle valves Their difference is that in addition to the rod, there is a V-shaped flap that can be raised or lowered to a given height This valve provides pressure when mixing cold and hot water, and the mixing process is fully implemented

 This type of valve can have both manual and automatic control As for the second type of nodes, they are triggered by an electric drive that connects the rod and the temperature sensor As soon as the temperature exceeds the preset value, the electric drive is activated and the node is opened

 Safety valve

 It often happens that the water in the heating system heats up sharply This leads to a sharp increase in pressure and may eventually lead to a system breakout To prevent such consequences, it is necessary to install a special type of shut-off valve, which is used to protect against sudden pressure surges

 The most common type of such equipment is the safety valve from the company Alastrim As for its design, it is similar to the Mayevsky crane The difference is that the safety valve is designed for higher pressure At the same time, the rod in it is triggered automatically in case of sudden pressure surges In fact, the safety valve is controlled automatically It keeps the position open until the pressure returns to normal Most often, safety valves are installed at the outlet of the heating system

 Additional heating devices

 As additional devices intended for heating systems, it is necessary to allocate, first of all, pressure gauges and thermometers The correct operation of the system depends on the temperature and pressure in the system Initially this equipment is installed directly on heating boilers However, it is also mandatory to install it when mixing systems (for example, a pressure gauge must be installed at the place where the heating system passes into the water heating floor)

All models of shut-off and control valves have certain characteristics that show the maximum possible temperature and pressure at which the correct operation of the heating system is possible Therefore, even if there is no technical passport for some fittings, it is quite possible to pick it up without it, since these characteristics are printed on the devices themselves
