What are the advantages of ball valve with drain？
DBV Electric ball valve with drain system valve,the utility model discloses a filter ball valve with sewage discharge function, which is characterized in that it comprises a valve body, a valve is arranged at the water inlet end of the valve body, a temperature and pressure gauge is arranged at the water outlet end, an inclined sewage pipe is arranged between the temperature and pressure gauge and the valve, the sewage pipe is inclined by 30-50 degrees, and a filter screen is arranged inside the sewage pipe, A blowdown movable joint with a plug cap is arranged at the port, an independent small valve is arranged on the blowdown pipe, the blowdown pipe and the valve body are integrally formed; The utility model has the advantages of convenient sewage discharge, reducing the overall leakage point and prolonging the service life.
Here’s pros of ball valve with electric actuator:
1. A locking hole is set at the fully open and fully closed positions of the valve to prevent misoperation by non staff.
2. A step is set at the lower part of the valve stem to prevent the abnormal rise of the internal pressure of the valve from falling out of the valve stem.
3. A fire-resistant sealing ring is set between the ball and the valve seat, which still has the sealing effect after the valve seat is burned.
4. Quick switch, flexible opening and closing, long service life, safe and reliable.
5. Pneumatic and electric ball valves can be controlled remotely and centrally, and can meet the needs of computer program control.
The thrust bearing reduces the friction torque of the valve stem, which can make the long-term operation of the valve stem stable and flexible,a spring is set between the ball, valve rod and valve body to export the static electricity generated in the switching process.As Teflon and other materials have good self lubrication and small friction loss with the ball, the service life of the ball valve is long.The lower mounted valve rod and the convex step at the head of the valve rod prevent the valve rod from ejecting. If the valve rod seal is damaged by fire, a metal contact can be formed between the convex step and the valve body to ensure the valve rod seal.The fluid resistance is small. The ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has a very small fluid resistance.
