shut-off valves
Shut-off valves are considered to be the main type of pipeline fittings, the presence of which is a prerequisite for any pipeline system in modern construction.
Shut-off valves are shut-off devices for piping systems, which are designed to completely cover and open the flow of the working medium. But some types of shut-off valves can be designed not only to fully open and close the flow of the moving medium (valves), but also for its partial overlap, by regulating the intensity of the medium transported in the pipeline (taps, valves, gates).
The shut-off devices themselves are available with several types of control, have different designs and configurations, are made of different materials, can be used for working environments of different origins, and are operated in engineering systems with different purposes. But the main difference of the shut-off valve is in which direction the closing element moves, when it is moved to stop the flow of the working medium. Depending on this factor and the types of shut-off valves which are issued are classified:
-Latches – the overlapping element of the device moves perpendicular to the main flow.
-Valves (valves) – closes or the regulating element of the device moves along the flow direction.
-Ball valves – overlapping or regulating element of the device moves around the axis of the device, perpendicular to the flow.
-Disks (valves) – overlaps or regulates the device, moves around its own axis, located perpendicular or at an angle to the flow.
All types of shut-off valves are made of corrosion-resistant materials. As a rule, it is stainless steel of various brands, malleable cast iron with anti-corrosion coating, non-ferrous metals (brass, bronze), titanium and aluminum, polymer plastic (polyethylene, polypropylene).
They are equipped with handles and steering wheels (flywheels) for manual control, mechanical gearbox, electric, pneumatic or hydraulic drive.
Also shut-off valves are installed on the pipeline in several ways:
-welding method – welding of a branch pipe of the device directly to a pipe, flange connection by means of flanges and fastening elements, -threaded connection by means of shaped parts and fittings with an external or internal carving.
Depending on the type of pipeline shut-off valves, the necessary technical parameters of the system are determined, where it can be effectively operated: operating pressure in the pipeline, type of medium transported (liquid, gaseous), type of medium (abrasiveness, toxicity, presence of impurities), working medium temperature .
Shut-off valves for pipelines can be used in many areas of construction and industry:
-water supply and sewerage systems,
-heating and heating systems,
– gas and cold supply mains,
-air ducts for ventilation and air conditioning,
-Housing and communal services enterprises,
-food production,
-petrochemical industry,
-fire extinguishing systems.
