4. Manual knife gate to the clamp in round after the installation of sleeve device at the top, can make the activity components all closed, Industrial Valves disc and stem of lead screw transmission will not unsmooth by lubricating oil dry. Gate wedge contact structure is set on the back of tight sealing faces are wedge clamping piece, the other side of the body corresponding to the clamping piece set to adjust the top wire. Manual knife gate valve is a valve technology to the clamp. In the process of opening and closing, ram and tightly closed surface sees fit and using a special preset, less friction, durable not easy to bad. Fitting for use in liquefied petroleum gas pipeline containing dust or wood tar. 2. Manual knife gate see fit to the clamp and the use of metal to metal hard tightly closed, or right and the use of metal to rubber soft tightly closed. 1. Manual for new varieties of is knife gate Industrial Valves, large and small, light weight, light material saving, water, coal slurry, slag slurry water, air, water mixture, water supply, paper making, mining and so on ideal product of underemployed. Practical new have shorter body structure, light weight, seat tightly closed surface can be protected from medium scour, tightly closed surface average, joint tightness and pressure in the process of closing to dust particles, wood tar, etc on the surface of the seat tightly closed scraped and convenient sewage strengths. Based on circular tightly closed, and that appropriate and use the international advanced so far floating tightly closed structure, get on and tightly closed to the extent of the pipe with fixed number of year of survival, so the group grew on the valve use fixed number of year of survival. Especially in dust and dry low background normal office long time. 3. Hand on the knife gate to the clamp tightly closed broke the normal way of tightly closed, see fit and use cover structure, be tightly closed by plane or on the size of the surface of rectangular tightly closed to the circumference of a circle the size of a small plane or surface tightly closed, tightly closed performance increase greatly. 。 Ram sees fit and using single ram, a side and the valve seat tightly closed, the back and wedge contact between the body to the other side, tightly closed surface as opposed to a media Marine valve flow direction. To solve the problem is to supply a structure length is short, big and small, tightly closed good, use fixed number of year of the survival of long gas knife gate valve. Cover the constituents of the valve body, disc, valve cover, stem and drive for structure, for its unique place, the body is the most simple surface plate structure, and pipeline a petition to the clamp.
