England electromechanical valve using media as a cut-off, in the full flow through, then the pressure medium to run minimal loss. Valve is usually applied to less frequent opening and closing, and keeping the shutter fully open or fully closed condition. Not suitable for use as a regulator or throttling. For the high-speed flow of medium, open the gate in local conditions can cause vibration of the gate, while the vibration it might damage the gate and seat sealing surface, while the throttle damper will suffer erosion of the medium. Form steel gate from the structure, the main difference is that the sealing element used. According to the form of the sealing element, often divided into several different types of valve gate trench, such as: wedge gate valves, parallel gate valve, parallel Gate Valve, double plate wedge gate and so on. The most common form of wedge gate and parallel gate valve. The role of this type of valve is only allowed media to flow in one direction, and stop the flow direction. Usually the valve is automatically work in a direction of flow of the fluid pressure in the role of stainless steel valve, the valve opens; opposite direction of fluid flow from the fluid pressure and the valve from the coincidence of acting on the valve seat, thereby cutting off the flow . Check them belong to this type of valve, which includes swing check valves and lift check valves. (5) the amount of leakage flow valve is closed from flowing out of the chamber into the oil leak will affect the minimum amount of stable flow valve, so the amount of internal leaks as small as possible. (6) Other work oil temperature can affect the viscosity of the flow leaving the change, and therefore, often used for oil temperature insensitive thin wall orifice. Conditions of a flow control valve using a pneumatic flow control valve should be set at the inlet pipe valve. 2 flow control valve to send cement should be less than 1% water content, temperature no higher than 120 ℃ valve, non-hybrid slag and clumps. 3 Install the slope should be within the range of 6% to 14%. 4 Flow control valve requires pressure 4.0-5.KPa, need air volume 1.5-2.0m [3] / m [2] .min. Performance should be consistent with a flow and other parameters as specified in Table 3.4. 2 flow control valve should be accurate and reliable control of material flow. When the three flow control valve work, the flanges are not allowed junction leakage.
