Description
Technical field
The utility model relates to high platform butterfly valve, particularly relates to high platform full-metallic hard seal butterfly valve.
Background technique
Be conventionally used to sanitation-grade or use butterfly valve to be generally butterfly plate full lining fluorine butterfly valve to the very high operating mode of medium requirements, this kind of butterfly valve can effectively ensure the pollution-free of medium, but due to pressure medium and the length of service time, due to butterfly plate whole position lining fluorine, butterfly plate and valve seal area is caused to increase, the moment of opening also just increases, and affects valve operability in use.
A kind of full-metallic butterfly valve of prior art model utility, but this kind of butterfly valve dish plate need to arrange valve seat, valve seat is once damage and need to change together with whole dish plate, and maintenance cost is large, haves much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of structure simple, the detachable high platform full-metallic hard seal butterfly valve with changing of valve seat.
For realizing the utility model object, provide following technological scheme: high platform full-metallic hard seal butterfly valve, it is characterized in that comprising cylindric valve body, the valve stem casing at body wall center, be inserted in the valve rod in valve stem casing, valve stem end peaks in the end cap on the corresponding sidewall of valve stem casing, valve rod is provided with dish plate, dish plate right flank is provided with valve with changeable valve seat, described valve with changeable valve seat comprises sealing dish pressing plate, dish plate seal ring, valve seals, pressure ring, described dish plate right flank edge arranges ladder shelves, dish plate seal ring is placed on ladder shelves, dish plate seal ring surface pressure is connected to sealing dish pressing plate, sealing dish pressing plate arranges a circle screw around the center of circle, screw is fastenedly connected through dish plate seal ring and dish plate, on the right side of valve body, inwall is provided with groove, valve seals is connected with in groove, fitted seal outside valve seals inwall and dish plate seal ring, pressure ring is crimped with outside valve seals, pressure ring is fastenedly connected by screw and valve seals.
As preferably, the surface of contact of dish plate ladder shelves and dish plate seal ring is provided with full-metallic dish plate sealing gasket.
As preferably, on the right side of valve body inboard wall groove and valve seals surface of contact on be provided with valve seal pad.
The utility model beneficial effect: the utility model is improved the quality of products by all-metal setting, and valve with changeable valve seat structure is set solves the large defect of full-metallic butterfly valve maintenance cost, structure is simple, convenient operation.
