Z41Y-320P stainless steel high-pressure flanged gate valve Z41Y-320P

Brand [Z41Y-320P stainless steel high-pressure flanged gate valve ] Ke, Confucianism of Shanghai, used in Class150- 2500LB, operating temperature – 29- 425 ¡æ(carbon steel) Or – 29- 500 ¡æ(stainless steel) Pipe lines small-bore at,it is the above-mentioned without being if gone beyond for operating range please contact sales force of our company, arrange to make to order! Used for blocking or putting through the medium in the pipe line, choose different materials, can be suitable for many kinds of mediums such as water, steam, oil, nitric acid, acetic acid, oxidative medium, urea respectively. It is more to employ on the petroleum pipeline. Z41Y high-temperature high-pressure flanged gate valve operating principle: The high-temperature high-pressure flanged gate valve has three kinds of body to overlay and connect and design the form. Valve Ke, Confucianism of Shanghai, first of brand whether body build the intersection of bolt joint and the intersection of forged steel and discharge gate, connect valve that the form is designed according to this kind, its valve body and valve cover use the bolt joint, the winding type shim is sealed, the advantage is to benefit maintenance. The second kind of body is covered on the forged steel discharge gate of welded connection, connect valve that the form is designed according to this kind, weld sealing completely with its valve body and valve cover, the advantage has not been let out outside. The third kind is a self-fastening valve cover forged steel discharge gate of pressures, connect valve that the form is designed according to this kind, its valve body and valve cover are connected with spiral shell’s mosquito, the internal pressure is sealed from the sealing ring, the advantage is that the internal pressure is the greater, the better its sealing property is.

Item Model:

[The performance parameter of main frame of Z41Y-320P stainless steel high-pressure flanged gate valve ]:

7.Applicable temperature: 0 ¡æ is less than or equal to 550 ¡æ

8.The main material of valve body: Stainless steel, cast steel, carbon steel, casting iron,etc..

9.Applicable working condition medium: Water, oil, steam,etc..

[When Z41Y-320P stainless steel high-pressure flanged gate valve ] discharge gate is closed

    Shanghai the intersection of Confucianism and Ke valve brand sealing surface can only rely on the medium pressure to seal, namely rely on the medium pressure to press the sealing surface of the damper towards the valve seat in the other side to guarantee the sealing of the sealing surface, this is self sealing. Most discharge gates are adopted and forced the sealed one, when the valve is closed, should rely on the external force to press the damper towards the valve seat by force, in order to guarantee the leak tightness of the sealing surface.

    Damper of discharge gate make straight-line together with valve stem, ask the intersection of lifting arm and the intersection of floodgate and valve (call bright the intersection of pole and discharge gate also) . Usually there is trapezoidal thread on the lifting arm, through the channel guide on valve terminal nut and valve body, turn rotary motion into the intersection of straight line and sport, operate running torque, turn into, operate thrust while being only.

[Z41Y-320P stainless steel high-pressure flanged gate valve ], while opening the valve

    Shanghai the intersection of Confucianism and Ke valve brand look on as the intersection of damper and lifting height equal to the intersection of valve and 1 of path: When the 1 time, the fluidic passway is totally unblocked, but during operation, this position can’t be monitored. At the time of in-service use, regard vertex of the valve stem as the sign, the position that namely can not start, wide-open position as it. For consider temperature variation present lock phenomenon extremely, usually at reaching of dot location, 1/2- 1 of the circles changebacks again, the position as the wide-open valve. So, the wide-open position of the valve, according to the position of the damper (namely the journey > Come to fix.
