The structure characteristics and installation instructions of the drain valve

     Structural characteristics

     1.The valve body and valve cover with clamp connection, compact structure, convenient disassembly, convenient installation, pipewelding connection.

     2.The pressure seal structure, the sealing ring shaped byasbestos packing is made, the higher the pressure medium, the seal is better.

     3.Medium from the branch flows downwards discharge.

     4,The valve piston type structure, and boronizing. Corrosion resistance, erosion resistance. Long service life.

     Installation instructions

     1.More than through the drain valve must be installed vertically in horizontal pipe.

     2.Of the pipeline after cleaning, can install valve.

     3.Handwheel counterclockwise drive spool moves up the stem,sealing face off, the diversion valve seat gradually out of the valve seat hole, forming narrow gap, media through the orifice seat on the symmetry into the seat inside, a small amount of media flow through the slit, and gradually reduce the system pressure.

      4.To turn the hand wheel counterclockwise, upward movement of the spool valve seat cavity, the orifice from the diversion seat,more medium through the diversion seat and valve smooth exhaust throttle sleeve.

       5.To turn the hand wheel counterclockwise, the valve core tomove to the full open position, at this time, medium pressure is greatly reduced, a large number of impurities can be set directly from the throttle valve discharge hole, and the inverted vortex formed at the sealing seat, we clean the sealing surface, preventadhesion of impurities on the sealing surface.

        6.Clockwise rotating valve, valve stem drive spool down, this time the sewage has ended, the system pressure is low, the throttle valve area is gradually reduced, the guide sleeve close to the seat, and change the media flow, medium after a certain speed by cutting through the valve and valve sealing surface, the gradual strengthening of the sealing surface of the cleaning efforts.

     7.To turn the hand wheel, the diversion valve seat into the valve seat hole, forming a narrow throttle, due to sewage near the end,the medium has less impurity, the guide sleeve and the narrow gap between the valve seat to prevent the tiny impuritiesremaining into the sealing surface, medium fast flow through the narrow, thoroughly clean the sealing surface, ensures zero leakage to achieve the sealing contact.

   8 to turn the hand wheel, valve and seat contact. To achieve sealing.

   The drain valve, drain valve size, discharge valve, discharge valve principle; drain valve and the valve body and valve cover withclamp connection, the drain valve has the advantages of compact structure, convenient disassembly discharge valve dischargevalve, easy installation, the drain valve pipe welding connection.The drain valve with pressure seal structure, the drain valvesealing ring is made of molded asbestos packing material, the higher the pressure medium valve, sealing the better. The drain valve medium from the branch flows downwards discharge.Discharge valve for the piston type structure and boronizing. The drain valve corrosion erosion resistance and long service life.
