Product Name: Station pressure valve Model: Z61Y, Z961Y drive: manual, electric, pneumatic, bevel gear Connection: welding, flange structural forms: wedge seal structure: Hard sealing pressure range: 1.6-32Mpa nominal diameter: DN15-350 common material: WCB, chromium molybdenum steel, stainless steel, alloy steel plate: male workers brand products described ordering process high pressure power station gate valves, high temperature and pressure valve for nominal pressure PN16 ~ 32 MPa and P54 / 100V-P57 / petroleum, chemical, water, fire station and a variety of system piping 170V, the working temperature ≤540 ℃ (where P57 / 170V operating temperature of 570 ℃), the cut off or connected piping media. Applicable medium: water, steam and other oil products. Operating modes: manual, gear transmission, electric and so on. The gate valve opening and closing parts, the direction of movement of the fluid direction perpendicular to the gate, the gate valve can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surfaces, sealing surfaces the most common mode of gate valve forming wedge, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high when 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; also be made to produce small quantities of deformation gate in order to improve its process of, to make up the sealing surface angle deviations arising during processing, such gate board called the flexible gate. Valve closed, sealing surface can only rely on media pressure to seal, which rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the sealing surface of the seal, which is self-sealing. Most of the valve is sealed by force, that the valve is closed to rely on external pressure to force the gate valve to ensure that the sealing of the sealing surface. Gate valve with the valve stem linear movement, called the lift rod valve also called clear shot valve. Often movements are trapezoidal threaded rod, through the guide slot valve and the valve on top of the nut, and the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to diameter of 1: 1 times, the fluid channel is completely smooth, but at run time, this position can not be monitored. Actual use, is the apex of stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the location of a fully open valve. Therefore, the fully open position of the valve, according to damper position, that stroke is determined. Some valve, the stem nut is located at the gate, handwheel drive stem rotation, leaving the gate to upgrade, this valve is called the rotating rod valve or valve called the dark bar. Valve Principle closure member (shutter) move made fully open and fully closed off by the vertical direction via the centerline. The main gate valve selection Gate cut off or connected line of medium, is generally not a regulator or throttling. Classification Valve Valve according to different classification methods can be divided into: parallel gate valve, wedge gate, lift gate, rotating rod valve, fast opening and closing valve, necking valve, flat gate valve and so on. Valve characteristic fluid resistance, the applicable pressure, large temperature range, medium flow unrestricted, good sealing performance. Contact Shanghai-Valve Co., Ltd.
