GB Valve - 2014-01-22 11:32:28

Valve has fluid resistance , apply pressure, wide temperature range , etc. , is one of the most commonly used cut-off valve , cut off or connected line of medium . When the flow through the fully open , then the pressure medium run minimal loss . Valve is usually applied to less frequent opening and closing, and maintain the gate fully open or fully closed condition . Does not apply to the use of a regulator or throttling. For high-speed flow of the medium , the gate in local conditions can cause vibration of the gate , and the vibration it might damage the sealing surface of the gate and seat , and throttle damper will suffer erosion of the medium .

Domestic low-pressure valve is commonly used cast iron , cast iron gate valve cracking often occurs , serious problems shedding gate , cast iron gate valve stem easily corroded steel , poor quality packing gaskets , internal and external leakage serious. Low-pressure valve PN1.0MPa network replaces the traditional steel gate iron gate , effectively solve the iron gate of the housing and easy cracking , easy to fall off the gate , stem rust easily , not reliable sealing performance issues .

GB valve characteristics

( 1 ) Fluid resistance because the media path inside the valve body is straight and does not change its medium flows through the valve when the flow direction , so the fluid resistance.

( 2 ) When the valve opening and closing torque is small because the gate opening and closing movement direction perpendicular to the flow direction of the medium , compared with the closing valves, valve opening and closing more effort.

( 3 ) Medium flow unrestricted 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 ) Because of the shorter length of the structure vertical gate valve is placed in the valve body , and the 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 ) Two seal is easy to damage the sealing surface and the valve seat opening and closing the shutter and in contact with the relative friction between the easy to damage , and could affect the service life of the seal .

( 7 ) Start idle for a long time , the height shall be large due to the gate fully open or fully closed , the shutter opening and closing stroke is large , open with to a certain space, high dimensions .

( 8 ) The structure of more complex parts , manufacturing and maintenance more difficult , the cost is higher than the cut-off valve .
