The Spigot ball valve is a special type of ball valve, which is characterized by its connection mode using a jack design. This design allows the socket ball valve to be directly inserted into the pipeline during installation, simplifying the installation process and improving work efficiency. The closing part of the ball valve is a ball, and when the ball rotates around the center line of the valve body, the valve can be opened or closed. This design is not only used to cut off the flow of the medium, but also to change the flow direction of the medium, so it has a wide range of applications in pipeline systems.
Action working principle
The main function of the Spigot ball valve is to control the flow of fluid. It can be rotated 90 degrees to open or close the fluid in the pipeline, to achieve media cut-off, distribution and flow direction change. The ball valve has the characteristics of easy operation, simple structure and compact, and is widely used in various industrial and household fields.
The working principle of the socket ball valve is to realize the switching function by rotating the ball in the valve body. When the ball is rotated 90 degrees, the center of the ball hole is concentric with the center of the valve body opening, allowing fluid flow; When the ball is rotated to 90 degrees from the valve body opening, the ball hole is misaligned with the valve body opening, thus blocking the fluid flow. This design allows the port ball valve to open and close very quickly, and the operating torque is small, suitable for frequent operation environments.
Material type
Common materials of Spigot ball valve include polyvinyl chloride (PVC), reinforced polypropylene (RPP), polyvinylidene fluoride (PVDF) and chlorinated polyvinyl chloride (CPVC). These materials have good corrosion and temperature resistance and can be used in different temperature ranges.
To be specific:
1. polyvinyl chloride (PVC) : has good corrosion resistance, suitable for a variety of media, but not suitable for strong oxidants, aromatic hydrocarbons, ketones, chlorinated hydrocarbons .
2. reinforced polypropylene (RPP) : has good corrosion resistance and high strength, suitable for a variety of corrosive media .
3. polyvinylidene fluoride (PVDF) : has excellent corrosion resistance and high temperature resistance, suitable for a variety of strong acids, alkali and organic solvents .
4. chlorinated polyvinyl chloride (CPVC) : has higher heat and chemical resistance, suitable for high temperature and strong corrosive media .
The selection of these materials makes the plastic jack ball valve widely used in pure water, raw water, sewage, salt water, sea water and other fields, with light weight, simple installation and maintenance, long service life
Features of the Spigot ball valve include
1. compact structure : The flow path area between the valve body inside the ball valve and the import and export pipeline is not much different, and the flow path is almost straight, so the pressure loss is minimal.
2. easy operation : just rotate 90 degrees to complete the switch operation, easy to remote control.
3. strong applicability : suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions such as oxygen, hydrogen peroxide and other media
These features make it particularly suitable for low pressure, small diameter pipelines, especially where quick opening and closing are required. In addition, the sealing surface material of the socket ball valve is usually plastic, which has good sealing property, and when it is fully opened or fully closed, the sealing surface of the ball and the seat is isolated from the medium, avoiding the erosion of the medium on the valve sealing surface.
