Abstract

The invention discloses a fully-sealed welded nuclear grade valve, which comprises a valve body and a valve seat, wherein the valve seat is provided with a rotating shaft, an oil cylinder, a check valve, a first valve hole and a second valve hole; the rotating shaft is pivoted with a rotating valve plug; the oil cylinder is connected to the first valve hole in the valve seat; the end part of the oil cylinder is provided with an oil cylinder cover plate; the rotating valve plug comprises a valve cover and a rotating piston connected with the valve cover; when the valve is closed, the valve cover closes the second valve hole, the rotating piston is positioned on the port of the first valve hole; and a spring is tightly sleeved on the rotating shaft. The valve is highly airtight and free from leakage. Without torque, the valve can be opened easily.

Description

technical field [0001] The invention relates to a valve, in particular to a fully sealed and welded nuclear valve. Background technique [0002] Existing valves used in pipelines, especially those used in nuclear power equipment, are prone to leakage and fail to meet the required sealing standards; and due to the existence of torque, it is laborious to open. Contents of the invention [0003] The purpose of the present invention is to provide a fully sealed and welded nuclear valve. [0004] The present invention aims to solve the problems that the existing valves are prone to leakage and relatively laborious to open. [0005] In order to achieve the above object, the technical solution adopted by the present invention is: it includes a valve body and a valve seat, and the valve seat is provided with a rotating shaft, an oil cylinder, a one-way valve, a first valve hole and a second valve hole; There is a rotary valve plug, and the oil cylinder is connected to the first ...
