Description

Heat-resistant corrosion-resistant high-tightness valve seat structure Technical Field The utility model belongs to the technical field of valve seats, and particularly relates to a heat-resistant corrosion-resistant high-tightness valve seat structure. Background The valve seat is a key component in the valve, which cooperates with a closing member (such as a valve clack, a ball body and the like) to form a seal, and has the core functions of blocking the flow of fluid medium and bearing the impact of pressure, temperature and corrosive medium. The existing valve seat is usually fixed inside the valve body and is in direct contact with moving parts (such as a valve clack and a ball body) to form a sealing pair, but the valve seat is easy to cause more fluctuation of medium pressure due to larger impact force of the device when in use, so that the sealing effect of the device is poor or the situation of sealing failure occurs, and therefore, the valve seat needs to be upgraded and modified on the basis of the prior art. Disclosure of utility model The utility model aims to provide a heat-resistant corrosion-resistant high-tightness valve seat structure so as to solve the problems in the background technology. In order to solve the problems, the following technical scheme is provided: The utility model provides a high leakproofness disk seat structure of heat-resisting corrosion-resistant, includes the device body, this internal snap ring first and snap ring second that contains of device, all be equipped with the connector link on snap ring first and the snap ring second and snap ring first and the snap ring second, the spiro union has a screw thread section of thick bamboo in valve body first and the valve body second, screw thread section of thick bamboo is equipped with two sets of and screw thread section of thick bamboo one end and connects disk seat first and disk seat second, set up seal groove and disk seat first and disk seat second in the disk seat second, be equipped with seal ring first in the seal groove, be provided with the case between disk seat first and the disk seat second, the valve rod is connected to the case top, the spliced pole has been inserted to the connector link, the spiro union nut on the spliced pole.
