What is the difference between check valve and globe valve？
2022-04-07
The difference between check valve and globe valve is as follows:
The check valve is not tightened the handle, the stop valve has a handle
2. Globe valve
Expansion content:
1. Check valve
Check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container
2. Globe valve
Globe valve, also known as cut-off valve, is the most widely used valve. The reason why it is popular is that the friction between the sealing surfaces is small during the opening and closing process, it is more durable, the opening height is not large, it is easy to manufacture, and it is easy to maintain. Convenient, not only for medium and low pressure, but also for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve stem to make the sealing surface of the valve disc and the sealing surface of the valve seat closely fit to prevent the flow of the medium.

The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located. As a most important cut-off valve, the globe valve is sealed by applying torque to the valve stem, and the valve stem is in the axial direction. Apply pressure to the disc to make the sealing surface of the disc and the sealing surface of the valve seat closely fit, preventing the medium from leaking along the gap between the sealing surfaces
