Valve classification and application

(1) Cut-off categories: gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, etc. Truncated valves, also known as closed-circuit valves and globe valves, act to switch on or cut off the medium in the pipeline.

(2) Non-return type: such as check valve, check valve, also known as check valve or check valve, check valve is an automatic valve, its role is to prevent the back flow of medium in the pipeline to prevent the pump and drive motor Reversal, and leakage of container media. The bottom valve of the pump is also a check valve.

(3) Safety categories: such as safety valves, explosion-proof valves, accident valves, etc. The role of the safety valve is to prevent the medium pressure in the pipeline or device from exceeding the specified value, so as to achieve the purpose of safety protection.

(4) Adjustment type: Such as regulating valve, throttle valve and pressure reducing valve, its role is to adjust the pressure, flow and other parameters of the medium.

(5) Shunt categories: such as distribution valves, three-way valves, and traps. Its function is to distribute, separate or mix the media in the pipeline.

(6) Special-purpose categories: such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc. The exhaust valve is an essential auxiliary component in the pipeline system and is widely used in boilers, air conditioners, oil and gas, and water supply and drainage pipelines. It is often installed at high points or elbows, eliminates excess gas in pipelines, improves the efficiency of pipeline usage, and reduces energy consumption.

The common gate valves used in the market have been leaking or rusting for a long time. The elastic seat sealing gate valves produced by European high-tech rubber and valve manufacturing technology have overcome the defects of common gate valves such as poor sealing and rust, and the elastic seating valve The use of the elastic gate to produce a slight amount of elastic deformation compensation effect to achieve a good sealing effect, the valve has a switch light, reliable sealing, good elastic memory and service life and other significant advantages. Can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems and other body pipelines used as regulation and closure devices.
