High platform ball valves and flange gate valves belong to the same type of valve, with the difference being that their closing component is a sphere that rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. Two piece ball valve, three piece ball valve, is a widely used new type of valve
The working principle of a high platform ball valve is to rotate the valve to make it open or close. Ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium. They are widely used in various industries
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable, the sealing surface material of ball valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.
5. Easy maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement relatively convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball rotates 90 degrees, it should appear spherical at both the inlet and outlet to intercept the flow.
High platform ball valve is a relatively new type of ball valve, which has some structural characteristics of its own, such as frictionless switch, low sealing wear, and small opening and closing torque. This can reduce the specifications of the accompanying actuator. Combined with a multi turn electric actuator, it can achieve adjustment and tight cutting of the medium. Widely applicable to working conditions that require strict cut-off in petroleum, chemical, urban water supply and drainage, etc
