Product Name: Electric soft seal valve Product Model: RVCX / Z945X Drive: electric, hand wheel Connection: Flange structure: shutter seal structure: soft sealing pressure range: 1.0MPa-2.5MPa Nominal diameter: DN50-1400 Commonly used material: cast iron, cast steel nameplate: male workers brand products described ordering process RVEX electric soft seal valve can be equipped according to user requirements of various electric actuators, to achieve remote control and automatic control sensitive, reliable. easy installation .. it can be widely used in water, sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems and other fluid pipeline regulation and closure devices used as electric soft sealing valve The main component material NO. Part Name Material 1 Body gray cast iron, ductile iron, cast ductile iron 2 gate covered with EPDM or NBR 3 Stem Stainless steel 4 valve cover gray iron, ductile iron, cast steel 5 Bracket gray iron, ductile iron, cast steel 6 powerhead valve opening and closing member is a gate, 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.
