Abstract
The invention relates to an inlaid valve element and a manufacturing process thereof. The inlaid valve element comprises a valve element body and valve element slide groove protecting sleeves. The two sides of the valve element body are respectively provided with an inlaid groove used for installing the valve element slide groove protecting sleeves which comprise inlaid baffles. A locating groove is formed in each inlaid baffle. A plurality of locating holes are formed in each locating groove. The valve element slide groove protecting sleeves are installed in the inlaid grooves and mutually fixed through rubber coating. Due to the fact that the valve element slide groove protecting sleeves are made of high-temperature and wear resistant plastic parts, the wear resistance is good, and the service life of the valve element is prolonged. Due to the fact that the two sides of the valve element are inlaid with the valve element slide groove protecting sleeves, on one hand, the weight of the valve element is reduced, and on the other hand, production cost is saved.
