Product Description

Working principle of high pressure ball valve
Gb high pressure ball valve it has a rotation of 90 degrees of action, the cock body for the ball, with a circular through hole or channel through its axis. Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and very small torque can be closed tight. Ball valves are best used as switches and cut-off valves, but recent developments have designed ball valves to provide throttling and flow control, such as V-shaped ball valves.
The main characteristics of high pressure ball valve is its compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the sphere is often in a closed state, not easy to be washed away by the medium, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries. Ball valve body can be integral, can also be combined.

Advantages of high pressure ball valve
1 fluid resistance is small, full diameter ball valve basically no flow resistance.
2. Simple structure, small volume, light weight.
3. Tight and reliable. It has two sealing surface, and the sealing surface material of the ball valve is widely used in various plastics, good sealing, can achieve complete sealing. It has also been widely used in vacuum systems.
4. Easy to operate, open and close quickly, from fully open to fully closed as long as the rotation 90 degrees, easy to remote control.
5. Convenient maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the sealing surface of the valve.
7. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
8. Ball valves can be used in media with suspended solid particles because of their wipeability in the process of opening and closing.
High pressure ball valve features
The domestic production of ball valve manufacturers are more, the connection size is mostly not unified. It is mainly divided into the following categories:
JB/T2203-1999 "ball valve structure length" based on the general class. At present, most ball valve manufacturers in China are designed and produced according to this standard. Haian Valve Factory, etc. But this standard is not perfect, specifications are not complete, floating ball valve maximum nominal diameter DN1200, fixed ball valve maximum nominal diameter DN2000. According to the factory production of valve specifications and information, the floating ball valve nominal diameter minimum DN6, fixed ball valve nominal diameter minimum DN50. After research, the manufacturers connection size is not unified, in order to have a unified standard, the user in the selection and installation of the same specification can be exchanged, it is suggested that the national Institute of general Machinery JB/T2203-1999 "ball valve structure length" to be revised. Recommended design institute and users according to the standard selection, ball valve manufacturers according to the standard design and manufacturing.
High pressure ball valve operation and use
1. Before operation, ensure that the pipeline and valve have been washed.
2, the valve operation according to the actuator input signal size to drive the valve stem rotation is completed: forward rotation 1/4 circle (90°), the valve is off. Reverse rotation 1/4 turns (90°), the valve opens.
3. When the direction indicating arrow of the actuator is parallel to the pipeline, the valve is open; When the indicating arrow is perpendicular to the pipeline, the valve is closed.


High pressure ball valve maintenance


Having a long service life and maintenance free period will depend on several factors: normal working conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion data
