Background

The stop valve is also called stop valve, belong to the forced seal type valve, so when the valve is closed, must exert pressure to the valve flap, in order to force the sealing surface not to leak, when the medium enters the valve from the valve flap below, the resistance that the operating force needs to overcome, it is the thrust produced by friction force and thrust produced by pressure of the medium of valve stem and packing, the force of closing the valve is greater than the force of opening the valve, so the diameter of the valve stem is bigger, otherwise will happen the trouble of the valve stem top bending, after the valve appears from the self-sealing, the medium flow direction of the stop valve changes and enters the valve pocket from the valve flap top, at this moment, under the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, the diameter of the valve stem can be reduced correspondingly, meanwhile, under the medium, the valve of this form is tighter, the "three transformation of" of our country has stipulated, the flow direction of the stop valve, adopt from top to bottom uniformly, when the stop valve opens, when the opening height of the valve clack is 25% -30% of the nominal diameter, the flow reaches the maximum, which means that the valve reaches the full opening position, so the full opening position of the stop valve is determined by the stroke of the valve clack.

The stop valve has a plug-shaped valve clack with a plane or sea cone surface on the sealing surface, the valve clack moves linearly along the central line of the valve seat, and the valve rod moves in a mode (common name: hidden rod) or in a lifting rotating rod mode to control the flow of various fluids such as air, water, steam, various corrosive media, slurry, oil, liquid metal, radioactive media and the like.

When using the stop valve, can not be fine protect it, receive outside striking for the valve body warp, the leakproofness variation has increased the probability that the valve body leaked.
