Welded Check Valve
Introduction:
Welded check valve refers to a forged high-pressure check valve using butt welding or socket welding connection, which can automatically prevent the backflow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the side to the outlet side. When the side pressure is lower than the outlet side, the valve disc is automatically closed under the action of fluid pressure difference, gravity and other factors to prevent fluid backflow.
Features:
1. The opening and closing is convenient and quick, labor-saving, and the fluid resistance is small, which can be operated frequently.
2. Simple structure, small size and light weight.
3. The mud can be transported, and the liquid accumulation at the pipe mouth is the least.
4. Under low pressure, good sealing can be achieved.
5. The welding check valve has good adjustment performance
