Q41PPL排污球阀的英文翻译为：Q41PPL blowdown ball valve
I. Introduction:
Applicable media for Q41PPL blowdown ball valve: sewage, gas, oil, natural gas and acid-base corrosive media. Applicable temperature: -196-350℃. Driving methods: manual, pneumatic, electric, etc. Main uses: For various pipelines with a metal hard sealing working temperature of -29～425℃ (carbon steel) or -40～550℃ (stainless steel), it is used to cut off or connect the medium in the pipeline. By selecting different materials, metal-sealed ball valves can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. Adopting a new type of sealing material as the valve seat, the service life of the ball valve with polytetrafluoroethylene as the seal is increased by 3-5 times. It has the advantages of stable performance, reliable sealing, small friction, light opening and closing, high temperature resistance, wear resistance, oil resistance, corrosion resistance, long service life, etc. The blowdown ball valve is consistent with the stop valve, plunger valve and blowdown valve in structural length, expanding the application range of the ball valve. It is widely used in petroleum, chemical, rubber, paper, pharmaceutical and other industries, and can replace stop valves, plunger valves and quick blowdown valves.
II. Product Features:
1. Small fluid resistance, full-bore ball valve has almost no flow resistance;
2. Simple structure, small size and light weight;
3. Tight and reliable. It has two sealing surfaces, and the sealing surface materials of the ball valve are widely made of various plastics, with good sealing performance, which can achieve complete sealing. It has also been widely used in vacuum systems;
4. Convenient operation, rapid opening and closing, only 90° rotation from fully open to fully closed, facilitating remote control;
5. Convenient maintenance, the ball valve has a simple structure, the sealing rings are generally movable, and the disassembly and replacement are relatively convenient;
6. When fully open or fully closed, the sealing surfaces of the sphere and valve seat are isolated from the medium, so the medium passing through will not cause erosion to the sealing surfaces of the valve;
