High Platform Ball Valve Is Often Used As An Automation Basic Component To Control Fluids.
Sanitary Ball Valve is a basic component commonly used in automation to control fluids. It plays an extremely important role in industrial manufacturing. The common advantages of high-platform ball valves include strong sealing performance, convenient adjustment, and fast opening and closing speed. You can learn about the uses and precautions of our high-platform ball valves.
I. Uses and advantages of high-platform ball valves
(1) Small fluid resistance. The full-diameter high-platform ball valve has basically 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 high-platform ball valves are widely used in various plastics, with good sealing performance and can achieve 100% sealing. It has also been widely used in vacuum systems.
(4) Easy to operate, fast opening and closing, only need to rotate 90° from full open to full closed, which is convenient for long-distance control.
(5) Easy maintenance. The ball valve has a simple structure and the sealing ring is generally movable, which is convenient for disassembly and replacement.
(6) When fully open or fully closed, the sealing surface of the billiard ball and the valve seat is isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
(7) Wide application range, diameters from a few millimeters to several meters, from high vacuum to high pressure.
(8) Since the high platform ball valve has a wiping property during the opening and closing process, it can be used in media with suspended solid particles.
II. Precautions for high platform ball valves
High platform ball valves only allow the medium to flow in one direction, and there is a directionality during installation. The structural length of the high platform ball valve is longer than that of the gate valve, and the fluid resistance is large. During long-term operation, the sealing reliability is not strong.
The basic principle of high platform ball valve installation is low inlet and high outlet, and it can be installed according to the flow direction mark. If it is installed in the opposite direction, although it can also work in theory, when the high platform ball valve is closed, the pressure still remains in the billiard ball valve cavity, and the valve cover and upper seal are still under pressure, and the probability of billiard ball valve leakage will be greatly increased.
Since the inlet and outlet of the cut-off billiard ball valve are asymmetrical, the medium should flow through the valve port from bottom to top during installation, that is, low inlet and high outlet, so that the valve can be opened with less effort and the packing is not easy to leak. It truly plays the role of cutting off and regulating pressure and flow.
