江苏兰 valve General Equipment Co., Ltd. passed IS09001-2008 quality system certification, product certification through the national explosion-proof electrical products for Quality Supervision and Inspection Center, made explosion-proof certificate and coal safety certificate. 1 ball advantage. Fluid resistance, ball full bore little flow resistance. 2. Simple structure, small size and light weight. 3. Compact and reliable. It has two sealing surface, and valve sealing surface material widely used kinds of plastic, sealing, and can be completely sealed. In the vacuum system it has also been widely used. 4. Easy to operate, opening and closing rapidly wind electric gate valve from fully open to fully closed as long as the rotation 90 °, to facilitate remote control. 5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient. 6. In the fully open or fully closed, sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface. 7. Wide range of applications, from small to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied. 8. Since the ball valve opening and closing process wiping, so can be used for media with suspended solid particles. Jiangsu Lan valve General Equipment Co., Ltd. is a professional research and development, production and sales of high-tech enterprises valve actuators. Also known as the one-way check valve or check valve, its role is to prevent the line of medium back. Pump water off the end of the valve also belongs to check class. Opening and closing pieces by medium flow and forces to open or close the throttle valve to prevent the media back check valve called. Check valves are automatic valves, mainly used for one-way flow of media channels, only allowing media to flow in one direction, in order to prevent accidents. Usually adjustable air gate valve, the valve of the fluid valve opening under pressure, and flow from the inlet side of the outlet side. When the inlet side of the pressure lower than the export side, the valve automatically shut down the channel under the action of gravity of the fluid pressure in and of itself, prevent fluid backflow. Press the valve movement in different ways, mainly divided valve lift, swing and butterfly three categories. Lift check valve and shut-off valve body much like its larger fluid resistance. Such small-diameter high pressure valve, often using spherical valve. Swing check valve for fluid resistance is small, generally applies to small and medium-caliber, low-pressure large-diameter pipe, often providing a plurality of the valve on the valve channel separator become Orange Peel. Butterfly valve similar to the shape of the butterfly. It is simple, small fluid resistance. Check valves closed too quickly could cause liquid hammer in the liquid pipeline, noise, and even cause damage to the valve parts. To avoid this, a buffer can be used if desired check valve function to extend the closing time.
