Valves for water supply: types, characteristics and purpose

Shut-off valves for water supply is a special device that serves to shut off water flows in a certain area of the system. It is installed starting from industrial cleaning facilities and finishing with an apartment.

Classification of stop valves

This armature contains in its composition a whole set of fasteners, knots, devices, parts, which are used to regulate various flows. Among them we can distinguish the following elements:

• Valves;
• Gate valves;
• Cranes;
• Closures;
• Valves.

They are installed on various pipelines, in tanks and on units. These elements are activated by means of a special electrical device or manually. There are several types of equipment, such as valves for water supply. Types of elements are safety and mixing.

General characteristics of stop valves

The requirements for this type of equipment must meet the following standards:

• Material of manufacture - brass, steel, bronze, plastics, cast iron.
• Each element meets special operating conditions.
• The capacity indicator is quite high.
• The shut-off valves for water supply are designed for a certain pressure and temperature.
• An obligatory requirement is an anti-corrosion coating that prevents the appearance of rust.

Valves: Purpose

This equipment has an industrial purpose. With its help, the flow of gas or liquid substances can be completely blocked. Shut-off valves for water supply are now quite common. It is with the help of it that it becomes possible to ensure complete tightness in the pipeline. Waterproof valves are used in various fields, for example in sewerage, water supply and heating systems.

Locking disc (latches)

Any armature of such an analog contains a regulating and locking disc in its composition. Usually it has the ability to rotate around the axis and become perpendicular to the pipeline itself, which ensures constipation.

Such a valve can be adjusted manually or by means of an electric drive. In modern piping systems, these drives can be remotely controlled. This allows you to stop the flow in the pipeline at any time. For example, if an emergency occurs.

Disks, which are equipped with shut-off valves for water supply (photo can be seen in the article), are the most important elements. The only drawback of such details is their large size. However, to the positive characteristics can be attributed a small resistance and simplicity of the design of the valve. This element is mounted using a flange. There are several types of discs: weld (flat or butt) and collar.

The most advantageous in modern systems is considered to be ball valves, which are more suitable for use in similar systems.

Shut-off valves

Shut-off valves for water supply consists of certain elements, one of which is a valve. Its design is designed in such a way that it is possible to completely block the water flow in the system. The zolotnik takes two positions: open and closed. There are models of valves that help regulate water supply. They perform two functions simultaneously: locking and regulating.

Advantages of this species are as follows:

• Complete tightness;
• The possibility of using at high temperatures and pressure in the system;
• Simple repairs and maintenance;
• Can be installed in corrosive, vacuum and aggressive environments;
• High level of durability.

Disadvantages of check valves:

• The hydro resistivity is large enough;
• In some places the water supply system may become clogged;
• For pipes with a large diameter, installation is not possible.
