Cast Steel Angle Globe Valve with Handwheel
Insulation stop valve is a forced seal valve, so when the valve is closed, pressure must be applied to the valve to force the sealing surface to not leak. When the medium enters valve 6 from below the valve flap, the resistance to be overcome by the operating force is the friction force of the stem and packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the valve The diameter of the rod must be large, otherwise a failure of the stem bending may occur. From the appearance of the self-sealing valve, the media flow direction of the stop valve is changed into the valve cavity from above the valve flap. At this time, under the pressure of the medium, the force of closing the valve is small, and the force of opening the valve is large, and the diameter of the valve stem can be correspondingly Reduce. At the same time, this type of valve is also tighter under the influence of the medium. China's valve "three to give" has stipulated that the flow of the stop valve, shall be adopted from top to bottom.Adjusting Valve, Electric Adjusting Valve, Pneumatic Adjusting Valve, Bottom Valve,
