Bevel gear valve has the following advantages: 1, fluid resistance, sealing surface by erosion distressed medium and small brush. 2, open and close more effort. 3, medium flow unrestricted, non-spoiler, do not reduce the pressure. 4, simple shape, structure, length short, good manufacturing processes for a wide range. Bevel gear valve installation instructions: 1. The valve must be installed vertically mounted on a horizontal pipe, the media can be accessed from either side. Rinse after pipeline may Docket valve. 2. The valve, when used, should be fully open or fully closed, can not be adjusted using the valve opening and closing the valve member is a ram, 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.

(2) opening and closing torque is small, open and close more effort because the direction of movement of the gate with the media flow direction perpendicular to the valve opening and closing, compared with closing valves, valve open and close more effort. (3) the direction of medium flow unrestricted, non-spoiler, do not reduce the pressure medium can flow in any direction from the gate on both sides, can achieve the purpose of use. More applicable to the flow direction of the medium may change the pipeline. (4) the length of the shorter structure as gate valve is placed perpendicular to the valve body, and cut-off valve flap valve body is placed horizontally, so the structure is shorter than the cut-off valve. (5) good sealing performance full sealing surface by erosion small. (6) When fully open, the sealing surface by erosion of the working medium is smaller than the cut-off valve. (7) is relatively simple shape, good casting process, a wide range of applications.
