Abstract

The patent of the present invention relates to a fully welded ball valve disc seal structure, including a valve body, a cover body, a lower center shaft, a lower center shaft sleeve, a positioning mechanism, safety bolts and an O-ring, and the cover body is arranged on the valve body One end of the lower central shaft passes through the valve body and is connected to the cover body, the lower central shaft sleeve is arranged between the lower central shaft and the valve body, and a multi-functional The through hole, the positioning mechanism is arranged between the valve body and the lower middle shaft sleeve, the safety bolt passes through the cover body and is connected in the multifunctional through hole of the lower middle shaft sleeve, the inner wall of the multifunctional through hole Internal threads matching the safety bolts are provided on the top, and the O-ring is arranged between the lower center shaft and the lower center shaft sleeve. The invention can discharge the residual medium and impurities in the valve body through the opened multifunctional through hole, and solves the problem of difficult cleaning of the heating pipeline.

Description

technical field [0001] The patent of the present invention relates to the field of sealing technology, in particular to a fully welded ball valve disc type sealing structure. Background technique [0002] There are many sealing structures in reality, but few are used for all-welded ball valves, and with long-term use, the sealing structure will be damaged or malfunction. At this time, it is often necessary to scrap the whole, resulting in unnecessary losses. Therefore, in order to reduce costs and prolong service life, it is particularly important to design an all-welded ball valve disc-type sealing structure. Contents of the invention [0003] The purpose of the present invention is to discharge the remaining medium and impurities in the valve body through the opened multi-functional through hole, which solves the difficult problem of cleaning the heating pipeline, and invents a fully welded ball valve disc type sealing structure. [0004] In order to solve the above tec...
