The Industrial valve is the general name of several valves such as ball valve, plug valve as well as butterfly valve. And it is a kind of component for devices like electric actuator or pneumatic actuator. Due to the presence of new technology, the Industrial valve is able to possess higher performance and wider applications.

The purpose and comparison of ball valve globe valve and gate valve

Ball valves are evolved from plug valves. It has the same rotation of 90 degrees, except that the plug body is a sphere with a circular through hole or its axis. The ratio of the spherical surface to the passage opening should be such that when the ball is rotated 90 degrees, the spherical surface should be entirely present at the inlet and outlet to intercept the flow.

Manual valve safety operation procedures

Common manual valves, including ball valve, gate valve, globe valve, butterfly valve, plug valve, etc., are the most widely used valves. Their handwheels or handles are designed according to ordinary manpower, taking into account the strength of the sealing surface and the required closing force.

Exploration and analysis of marine valve development

Due to the relatively large variety of valves used in the marine's pipelines, this creates difficulties in preparing and revising the appropriate standards for valves. Another aspect is that the use of valves in current marine pipelines in China is mainly based on manual valves such as a globe valve and gate valve. Such industrial valves are still relatively insufficient in terms of weight, volume, and sealing.

Improvement of the ball valve seal

The cast ball valve is an ideal opening and closing device in the ash slag pipeline. The sealing on it directly affects the quality and service life of the valve. In the past, an O-shaped rubber sealing structure was adopted, in which an O-ring was placed in an annular groove machined on a shaft, and then assembled into a hole formed in the sleeve part to form a seal of the shaft and the hole.
