The advantages and fault principle of ash unloading ball valve


The ash unloading ball valves produced by Henan upper valve co., ltd include pneumatic ash unloading ball valves, electric ash unloading ball valves, hydraulic ash unloading ball valves, worm ash unloading ball valves, etc. the ash unloading ball valves can be closed tightly only by rotating 90 degrees with gas and a small rotating torque. Completely equal body cavity for the medium to provide a small resistance, DC channel. Usually think that the ball valve is suitable for direct use of opening and closing, the main feature of the ball valve is its own compact structure, easy operation and maintenance. The ball valve body can be integral or combined.

Ash ball valve use: ball valve in oil, natural gas, coal and ore mining, refining and processing and pipeline transportation system; in chemical products, medicine and food production; in hydropower, thermal power and nuclear power production system.

Pneumatic ash discharge ball valve specifications principle of the valve is the use of cast steel material manufacturing of low-pressure valves, wear-resistant sealing ring to do the sealing surface. The structure of the ash unloading ball valve and the fixed ball valve are basically the same. They are all fixed on the center point by the upper and lower shafts. Under the pressure of the medium, no displacement will occur.

The fault principle of the ash unloading ball valve: the general sealing ring is bitten or the valve seat is swollen to death. In this case, the fluid pressure should be turned off first, the power supply or the origin should be cut off, the valve should be removed, and then the valve cover should be opened to clean the garbage inside the valve. Then take down the valve seat, replace the sealing ring, and add lubricating oil to the valve core and valve body.

The advantages of pneumatic ash discharge ball valve: a fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. B. Simple structure, small size and light weight. C. close and reliable, the current ball valve sealing surface material widely used carbon fiber, PPL, good sealing performance, vacuum system has been widely used. D. easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 °, easy to remote control. E. easy maintenance, pneumatic ball valve structure is simple, the seal ring is generally active, disassembly and replacement are more convenient. f. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface. G. a wide range of applications, diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. Pneumatic ash ball valve has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily life.
