Description

Valve plate for knife valve Technical Field The utility model relates to the field of valve manufacturing, in particular to a valve plate for a knife valve. Background The valve plate is used as a valve core component of the knife valve, and the knife structure cuts into a fluid medium to realize on-off control and flow regulation of fluid in a pipeline. The wear-resistant and corrosion-resistant characteristics of the valve can effectively cut off impurities, prevent blockage, ensure the tightness and opening and closing stability of the valve, and can be widely applied to severe working conditions in the fields of chemical industry, papermaking, environmental protection and the like, and the reliability and the service life of the system are improved. The existing valve plate for the knife valve is mainly of an integrated structure, meanwhile, the upper end of the valve plate is connected through a single row of fixing bolt through holes, the valve plate needs to be replaced integrally when the replacement process is relatively complex, huge resource waste is caused by integral replacement, the risk of poor sealing exists, and the using effect is seriously affected. Disclosure of utility model An object of the utility model is to solve at least one of the technical problem that exists among the prior art, provide the valve plate for knife valve, aim at improving current valve plate for knife valve and do not consider in the use and not only cause huge wasting of resources but also have the risk that seals not tightly at whole change, seriously influence the technical problem of result of use.
