The plastic ball valve is evolved from the cyclone valve. Its enable and closing pieces are used as a sphere. The axis of the spherical wounding valve rotation is rotated 90 degrees to achieve the purpose of opening and closing. The plastic ball valve is suitable for the interception of the transmission process with corrosive media. The working temperature of the working temperature of different materials PVC 0 ℃ ～ 50 ℃, C -PVC 0 ℃ ～ 90 ℃, PP -20 ℃ ～ 100 ℃, PVDF -20 ℃ ～ 100 ℃ Essence Plastic ball valve has excellent corrosion resistance. The sealing ring uses EPDM and FKM; it has excellent corrosion resistance and extend the service life. Flexible and convenient use. Plastic ball valve overall ball valve leaks, high strength, and easy to disassemble connecting ball valves.
The plastic ball valve not only has simple structure and good sealing performance, but also has a small volume, light weight, small material consumption, small installation size, small driving moment in a certain nominal diameter, small One of the fastest valve varieties in the past ten years. Especially in industrial developed countries such as the United States, Japan, Germany, France, France, Italy, West, and Britain, the use of ball valves is very wide, and the use varieties and quantities are still expanding.
The working principle of the plastic ball valve is to be unblocked or blocked by the rotating valve stem. The switch is lightweight, the size is small, the seal is reliable, the structure is simple, the maintenance is convenient, the seal and the sphere are often closed, it is not easy to be eroded by the media, and is widely used in various industries.
The ball valve is a new type of valve that has been widely used in recent years. It has the following advantages:
1. The fluid resistance is small, and its resistance coefficients are equal to the pipe segment of the same length.
2. Simple structure, small size, light weight.
3. Tight and reliable. At present, the sealing materials of the ball valve are widely used in plastic and sealing, and they have been widely used in vacuum systems.
4. Easy to operate, fast opening and closing, as long as the full level to the full level, just rotate 90 ° to facilitate long -distance control.
5. Easy maintenance, simple ball valve structure, sealing circle is generally active, and it is more convenient for disassembly and replacement.
6. When open or fully closed, the cover of the sphere and valve seat is isolated from the medium. When the medium passes, it will not cause the erosion of the valve cover.
7. The scope of application is wide, from small to a few mm to a few meters, from high vacuum to high pressure.
