The difference between check valve and check valve
One way valve is also called a check valve, the two is the same kind of valve, meaning the same.
The same thing, called, is based on the difference in the use of the actionFor example, overflow valve and safety valve, back pressure valve, are the same thing, are in the one-way valve behind the increase of back pressure spring
1, one-way valve: is a typical seat valve, one-way valve Check, Valve, also known as check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow. There are two one-way valve one-way and right angle type. Straight through one-way valves are threaded and installed on the pipe line. The right angle one-way valve has threaded connections, plate connection and flange connection in three forms. Liquid control check valve, also known as blocking valve or pressure valve, which is the same as one-way valve, used to prevent reverse flow of oil. But in the hydraulic circuit needs the oil flow reverse flow, but also can use the control oil pressure, opens the one-way valve, causes the oil flow to be possible to flow in two directions. The hydraulic control check valve adopts a conical valve core, so the sealing performance is good. When the closed oil circuit is required, the valve can be used as the one-way locking of the oil circuit to maintain the pressure. Liquid control check valves control the leakage of oil, there are two types of internal and external leakage. In the oil flow reverse outlet, no back pressure in the oil pipeline can be used to vent type; otherwise, need to leak type, in order to reduce the control oil pressure2, check valve is only one kind of valve, it can be said that one-way valve is a kind of check valve,
