Product Name: wedge gate valve Model: Z41H driving modes: manual, electric, pneumatic, gear Connection: flanges, welded structural forms: wedge seal structure: hard seal pressure range: 1.6-16MPa nominal diameter: DN25- DN600 common material: steel, stainless steel, alloy steel plate: male workers Brand Product Description Related Products Ordering Process wedge gate valve applications: wedge gate valves are widely used in petrochemical, power plants, such as oil, steam pipeline for connect or disconnect the lifting device pipeline medium. In various types of valves, valve is the most widely used. It generally applies only to fully open or fully closed, can not be adjusted and throttling. Z41H wedge gate valve is generally used in the external dimensions of the valve is not strictly required, but also relatively harsh conditions of the occasion. Such as high temperature and pressure of the working medium, requiring the closure member to ensure long-term sealing and so on. Generally, the use of conditions or requirements when sealing performance, reliable, high-pressure, high-pressure cutoff (large pressure), low-voltage cut-off (pressure difference), low noise, cavitation and vaporization, heat medium, low temperature (cryogenic) recommended wedge gate valve. Such as the electric power industry, petroleum refining, petrochemical, offshore oil, urban construction water works and sewage treatment works, chemical and other applications in the field more. Wedge Gate Valve Features: 1, compact structure, reasonable design, the valve rigid, channel flow, flow coefficient is small 2, the sealing surface of stainless steel and tungsten carbide, long life 3, the use of flexible graphite packing, sealing, reliable, easy operation flexible 4, the drive for manual, pneumatic, electric, gear 5, the structure in the form of elastic wedge single gate, rigid wedge single slide double plate type wedge gate valve standards: the design and manufacture standard: GB / T 12234 -2007 structural length standard: GB / T 12221-2005 Flange Standard: GB / T 9113 pressure and temperature rating: GB / T 12224-2005 test inspection standards: GB / T 13927-2008 is a gate valve opening and closing parts, ram direction of motion perpendicular to the direction of flow, the valve can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high for 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate board called the flexible gate. When the valve is closed, the sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness 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 top of the valve guides and valve nut on 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 the diameter of the 1: 1 times, the fluid channel is completely smooth, but at run time, this position is not monitored. Actual use, is the apex of the 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 position of the valve fully open. Therefore, the fully open position of the valve, according to the position of the gate is determined that the stroke. Some valve stem nut 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 closure member Principle (ram) movement do fully open and fully closed off with a vertical path along the centerline. Valve selection Gate Valve is mainly used to cut off or turn on the line of medium, is generally not as a regulator or throttling. Category gate valve can be divided according to different classification methods: parallel gate valve, wedge gate valve, lift gate, rotary valve rod, fast opening and closing valve, necking valve, flat gate valve and so on. Valve fluid resistance characteristics, the applicable pressure, high temperature range, medium flow unrestricted, good sealing performance. Contact Shanghai-Valve Co., Ltd.
