double tightly closed improve plug valve with double ZuGeng and discharge function, the valve is equipped with pressure balance device, in case of abnormal booster system, and can detract from the resistance of the valve opening and closing of the moments. Seat tightly closed surface bulge, easy to tightly closed surface cleaning, tightly closed surface is not easy to store up the formation of crystal medium, or solid particles. Because this also is widely used in the fuel, liquefied gas, natural gas, smelting metal mine engineering, light industry, textile, ships dock, food and environmental protection water treatment of seventy-two lines, such as regulation, opening and closing of pipeline fluid.  open valve transmission make cock rise with structure, help and collapsed on both sides of the board, make the combination plug body and the valve tightly closed after the face to get rid of, to help plug body rotating 90 degrees to the whole paper valve. Cock body into three boards combination cylindrical body and tightly embedded rubber sealing faces on both sides of the board, middle for cylindrical wedgeplug. 。 Q: a: improve the plug valve structure way improve type tee plug valves have a variety of ways structure, improve the plug valve according to the tightly closed the material divided into soft hard tightly closed and tightly closed.  close the valve plug body by the transmission due to the structure which rotate 90 degrees to the closed position, then push the plug body loss, after contact with the bottom of the valve body on both sides of the plate down, no longer middle wedgeplug and then decreased, after cant push plate on both sides of the inlet side, the side panel of the soft tightly closed tightly closed surface and the body surface contact after subjected to compression and tightly closed. Its basic principle for the open when the cock rise, cock rotate 90 degrees to valve process can detract from the whole paper and body tightly closed surface friction; Close the valve when the cock rotate 90 degrees to the closed position after a decline with the valve body tightly closed surface contact tightly closed. Metal tightly closed body improve the plug valve is closed, can have dealt with wheels and the surface of the stem to the seat tightly closed to increase pressure, after increasing tightly closed pressure, can make the plug valves have better sealing performance closely.  2, hard tightly closed improve plug Industrial Valves  metal tightly closed to improve on both sides of the plug valve seat tightly closed surface can be tightly closed, limit the use of the valve is not affected by the media flow. Because it is compressed tightly closed circle metal surface contact each other, valves have fire prevention function. protection is very convenient, can be in not taking down the body from the line, after removing the end cover at the bottom of the body can make the pump change on both sides of the plate from valve body. Solid Marine valve commonly used in chemical industry device of high temperature occasion.  1, double tightly closed improve plug valve  double tightly closed to improve soft plug valve is tightly closed structure. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
