Shanghai high-Valve Co., Ltd. bolt has the world's leading production equipment and technical engineers, have the ability to national standards as well as various industry standards for manufacturing quality valves. Second, Shanghai high P48H rapid sewage valve plug Introduction Quick drain valve is evolved from the gate, the use of stem drive gear is rotated 90 degrees to enhance the aim to achieve open and closed. Quick drain valve is not only simple structure, good sealing, and small size, light weight, less material consumption, small installation size, especially the drive torque is small, simple, easy to open and close fast. In addition, rapid discharge valve according to the media properties, using a variety of materials to meet the requirements of various media conditions! Third, the Shanghai bolt high P48H rapid discharge valve structure features 1. Body and bonnet clamp connections, compact, easy to disassemble, easy to install, support tube welded connection. 2. With pressure from the tight seal, seals made from a molded asbestos packing, the higher medium pressure, sealing the better. 3. Media downward from the branch pipe into the sewage. 4. The valve is piston type structure, and boronizing process. Corrosion, erosion. Long service life. Fourth, the Shanghai high P48H rapid blowdown valve plug Installation Instructions 1. multi-way drain valve must be installed vertically on a horizontal pipe. 2. clean the pipe only after installation of the valve. 3. Turn handwheel stem drive spool gradually move sealing surface disengaged diversion poppet valve is gradually removed from the hole, forming a narrow gap, media symmetric orifice valve seat into the seat inside, a small amount of medium flowing through the slit, decreases the system pressure. 4. Continue handwheel counterclockwise, spool upward movement, the orifice seat out of the seat cavity diversion, diversion smooth discharge after the adoption of the throttle valve housing seat and more media. 5. Continue handwheel counterclockwise, spool move up to the fully open position, this time, the medium pressure greatly reduced, large amounts of impurities can be discharged from the orifice of the valve housing, and the formation of a vortex in inverted sealing seat, which continually Clean sealing surface to prevent adhesion of impurities on the sealing surface. 6. clockwise valve stem drive spool down, when sewage has ended, low system pressure, the valve sleeve orifice area decreases, the guide sleeve and close the valve seat, and change the media flow, medium After throttling a constant speed to do the sealing surface through the spool and gradually strengthen the sealing surface of the cleaning efforts. 7. Continue to turn the hand wheel, diversion poppet into the seat on the hole, forming a narrow throttle, since sewage near the end, the medium has fewer impurities, the slit between the guide sleeve and valve prevents residual reaches zero leakage minor impurities flow into the sealing surface, the medium flowing through the slit quickly, thoroughly clean the sealing surface, to ensure sealing auxiliary contact. 8. Continue turning the handwheel, valve and seal seat contacts. A seal. Standard drain valve, drain valve size, valve action sewage, sewage valve principle; sewage valve body and bonnet compact clamp connection, drain valve structure, easy disassembly drain valve, drain valve for easy installation, drain valve manifold is welded connection . Drain valve using pressure self-tight sealing structure, the drain valve seal is made from a molded asbestos packing, the higher the drain valve medium pressure, sealing the better. Drain valve manifold flows down into the medium by the sewage. Blowdown valve piston type structure and boronizing process. Drain valve anti-erosion corrosion and long service life.
