Abstract

The invention discloses a novel valve, comprising a valve body, the top of the valve body is fixedly connected with a valve cover by bolts, the inside of the valve cover is fixedly connected with a first bearing, and the inner cavity of the valve body is provided with a rotating shaft, the top of the rotating shaft passes through the first bearing and the valve cover in turn and extends to the outside of the valve cover, a sealing packing is provided between the rotating shaft and the valve cover, and one end of the rotating shaft outside the valve cover is sheathed There is a pressure ring suitable for the sealing packing, the bottom of the pressure ring extends to the inside of the valve cover, the bottom of the rotating shaft is fixedly connected with the first bevel gear, and the bottom of the valve inner cavity is fixedly connected with a riser , the left end of the riser is provided with a threaded pipe. The threaded rod of the invention drives the valve clack to move laterally, so that the pipeline can be sealed in two directions, which greatly enhances the sealing performance of the valve, so that even if one of the valve clacks is damaged, the liquid will not leak, and the service life of the valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a novel valve. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, diversion, prevention of reverse flow, pressure stabilization, diversion or overflow pressure relief. Valves can be used to control air, water, steam, various corrosive media, mud, etc. For the flow of various types of fluids, such as oil, liquid metal and radioactive medium, the existing valve only seals the pipeline through one valve disc, and the sealing effect is poor. Once the valve disc is damaged, it will cause immeasurable economic losses. Contents of the invention [0003] The purpose of the present invention is to provide a new type of valve, which has the advantage of good sealing effect and solves the problem of poor sealing effect of the valve. [0004] In order to achieve the above object, the present inventio...
