What are the characteristics of the valve manufacturing process?

Compared with the manufacturing processes of other institutions, the valve manufacturing process has the following characteristics: 1. The manufacturing process and inspection process of the valve blank are more complex. The casting blanks of the valves are complex thin-walled shell parts. The casting requires a smooth surface and clear characters, especially with few defects. To meet these requirements, a series of process measures should be taken during the casting process, such as selecting high-temperature-resistant molding ma

Understand the working principle, advantages and applications of pneumatic ball valves!

The pneumatic ball valve is evolved from the plug valve. The main difference between them is that while the plug valve rotates 90 degrees, the plug body of the ball valve is a sphere with a circular passage or flow channel passing through its axis. Its working principle is to open or close the valve by rotating the valve core. The pneumatic ball valve is lightweight and compact in size. It can be made in large diameters, has reliab

Under normal working pressure, what causes the leakage of the sphere?

The sphere has leaked. Under the normal operating pressure of the equipment, there was excessive leakage between the valve disc and the sealing surface of the valve seat. The reasons for this are as follows: five points. 1. Dirt has fallen onto the sealing surface. To solve this problem, use an extension wrench to open and close the valve several times to flush away the dirt.
