Background

At present, ball valves, butterfly valves, gate valves, stop valves and the like are commonly used for pipeline valves used in petroleum, chemical industry, metallurgy, electric power, light industry, building materials and other industries in China. Because the medium in the bag box is a gas reinforcing body, a liquid reinforcing body and the like, solid stickies and crystals are separated out in gas and liquid, and some media have great harmfulness, are explosive and flammable and are easy to leak, the ball valve or the hard sealing butterfly valve and other valves cannot be opened and closed in place, and are inflexible to rotate, poor in sealing performance and short in service life. The existing hard seal butterfly valve is of a straight-through structure, two sides of the butterfly valve are sealed, when the butterfly valve is opened, the valve plate is transverse to the axial direction, so that the flow resistance of a medium in a pipeline is increased, the pressure drop is large, the tightness is poor, and the butterfly valve is inconvenient to maintain. Therefore, the problem of solving the above existing problem is that we are not ready to deal with things at present.

In the above-mentioned high temperature resistant aseptic discharge valve, the valve body is square, and its central point puts and has the passageway, the valve plate is located the passageway inboard.

In the above-mentioned high temperature resistant aseptic discharge valve, be equipped with bellied rib on the valve body up end.

In the high-temperature-resistant sterile discharge valve, the valve plate is provided with an abutting end which abuts against the channel to form a seal.

In the above-mentioned high temperature resistant aseptic discharge valve, the valve rod can drive the eccentric rotation of valve plate through rotating.

In the above-mentioned high temperature resistant aseptic discharge valve, the valve cover is screwed inside the passage.

The utility model has the advantages that: this product flexible operation, long service life, it is convenient to maintain, and the medium pressure drop is little, and simple structure especially all has the medium that solid viscidity thing and crystallization precipitate to solid, gaseous reinforcement body, liquid reinforcement body, gas and liquid in, has special performance advantage, makes sealing performance better, and auto-lock and wear compensation can be realized to the setting of eccentricity, and the setting of eccentricity can realize opening and close slim and graceful flexibility. The product can also be used for flow regulation and can replace butterfly valves with gate valves, stop valves, ball valves and other structures.
