The kinds of valves and application
-
(1) The truncation: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve etc. Truncation kind of valve is also called closed valve, cut-off valve, its role is connected or truncated medium pipeline.
(2) Check: such as check valve, check valve, also known as one-way valve or check valve, check valve belongs to a kind of automatic valve, its role is to prevent the backflow medium pipeline, prevent the pump and drive motor reversal, and the container medium leakage. The bottom valve of the pump suction off also belong to the check valve class.
(3) Security: such as relief valve, explosion-proof valve, accident valve, etc. The role of safety valve is to prevent the device or in medium pressure in excess of the prescribed value, so as to achieve the goal of security and protection.
(4) Adjust the class, such as regulating valve, throttle valve and the pressure reducing valve, its function is to regulate parameters such as pressure, flow rate of the medium.
(5) Shunt: such as distributing valve, three-way valve, steam trap. Its role is assigned, separation or mixed medium pipeline.
(6) Special purpose: such as pigging valve, exhaust valve, drain valve, exhaust valve, filters, etc. Exhaust valve in the pipe system is indispensable auxiliary components, are widely used in boiler, air conditioning, oil and gas, water supply and drainage pipeline. Often installed in the place such as the commanding heights or bend, get rid of extra gas pipeline, pipe road use efficiency and reduce energy consumption.
