The main advantage of cement tank cement tank pneumatic discharge valve pneumatic discharge valve of simple structure, small size, light weight, low cost, this feature is particularly notable butterfly, install underground passage at high altitude, after two five-way solenoid valve easy to operate controls, can also adjust the flow medium. Fluid resistance is small, while the large-diameter pneumatic butterfly valve is fully open and effective flow of larger, open and close rapidly effort, pull the disc rotation angle of 90 to complete the opening and closing, due to the shaft side dish wrench media force nearly equal, while the opposite direction of the torque generated, and thus a smaller opening and closing torque, low pressure can achieve a good seal, butterfly valve seal materials NBR, Viton, edible rubber, PTFE lining so good sealing performance, including sealing butterfly advantages of hard and soft valves for heavy metal sheets stacked with a metal seal and a resilient seal, both at low temperatures have excellent sealing properties. Cement tank pneumatic discharge valve Product Description: The main switch for silo bins, hoppers and equipped with powdery or granular materials. Can be applied to deal with all powdery and granular materials, the use of the material itself gravity valve closure and pneumatic transport of dry materials. Can be installed below the hopper, bin, silo, spiral or other type of conveyor, and connecting the pneumatic conveying line. Because of the special structure and the use of this valve engineering materials, it is always a very economical and very efficient choice. For cement tank filter, cement mixing plant warehouse roof ESP. Cement tank pneumatic discharge valve Features: single flange valve with top flange and folding parts, suitable for connecting a flexible sleeve double flanged valves, top and bottom flanges of the same cast from the valve by gravity body, die-cast body strength higher than the rotary valve plate using polymer materials, less wear-resistant components, lightweight, easy to handle. Cement tank pneumatic discharge valve in the opening, the shape of the body and disc opening formed in the front end of the valve shaft as the center, formed on both sides to complete the different states, the disc along the flow direction and move the front side, and the other countercurrent direction moving water side, so one side of the body and the valve plate is formed like a nozzle-shaped openings, similar to the other side of the orifice-shaped openings, fast nozzle orifice side than the side of the flow rate, and the following will be the throttle valve side negative pressure, often have rubber seals off. Cement tank pneumatic discharge characteristics of a butterfly, open and close easily and quickly, saving, fluid resistance, can often operate. 2, simple structure, small size and light weight. 3, can carry mud accumulation of fluid in the pipe mouth least. 4, low pressure, can achieve a good seal. 5, regulated performance. Cement tank pneumatic discharge valve is closed parts (valve or disc) to the disc around the valve axis to achieve the opening and closing a valve in the main pipeline from the off and throttling. Butterfly is a disc-shaped opening and closing parts of the disc, in the valve body rotating around its own axis, so as to achieve the purpose of opening and closing or adjusting. Valve fully open to fully closed is usually less than 90 °, butterfly and butterfly stroke itself is not self-locking capability, in order to position the disc to install the worm gear on the stem. Aluminum alloy body, steel valve plate, BNR rubber seals, covered with wear-resistant polymer materials processing.
