Abstract
The utility model relates to a valve clack, which is formed by a sheet steel, the polytetrafluoroethylene resin added with the polyphenyl fat resin and a sheet made of spun glass. The utility model is glued by the perfluoroethylene-propylene copolymer or the meltability polytetrafluoroethylene under the high temperature. The utility model is resistive in attrition, press and temperature and good in sealed capability.
Description
The utility model relates to a kind of valve block.
At present, the valve block that uses in devices such as compressor mostly is that metal such as stainless steel manufactures, and its shortcoming is a quick abrasion, and also fast to the valve body wearing and tearing that are mated use; Also useful plastic material is manufactured valve block, but its easy temperature distortion, rigidity is low, and sealability is bad.
The purpose of this utility model is to improve the shortcoming of prior art and provides that a kind of wear-resisting, rigidity is big, good seal performance, and to being mated the little composite valve of valve body wearing and tearing of use.
The purpose of this utility model is to realize like this, it is the thin slice of being made by steel disc, polyflon interpolation polyphenyl fat resin and glass fibre, through perfluoroethylene-propylene or Meltability polytetrafluorethyletubular hot pressing is bonding forms, wherein the weight ratio of polyflon, polyphenyl fat resin, glass fibre is 1:0.25-0.35:0.15-0.25.Hot pressing temperature is 350 ℃-360 ℃.
The utility model valve block is wear-resisting, withstand voltage, heatproof, good seal performance, uses indeformablely for a long time, has reduced the abrasion to valve body, can be used in all kinds of required equipment.
