Abstract

The invention discloses a high-temperature-resistant gas one-way valve. The high-temperature-resistant gas one-way valve is characterized by comprising a valve body, a first cavity is formed in the bottom end of the valve body, a second cavity is formed in the side wall of the valve body, the first cavity communicates with the second cavity, a valve deck is installed at the top end of the first cavity, a stepped hole is formed in the first cavity and located below the second cavity, a conical sealing surface is ground on the stepped hole, a sealing valve body is provided with a valve element assembly (3), the valve element assembly is located in the first cavity, a pressing assembly is installed on the valve deck and used for fixing the valve element assembly, and a sealing assembly is installed on the valve element assembly. According to the high-temperature-resistant gas one-way valve, the sealing and heat-insulating properties are good.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to a high-temperature-resistant gas check valve. Background technique [0002] The one-way valve is a directional control valve in which the air flow can only flow in one direction and cannot flow in the opposite direction. The compressed gas medium enters from the inlet, and the valve port of the one-way valve is opened by overcoming the spring force and friction force, and the gas medium flows from the inlet to the valve body. When there is no compressed gas medium at the inlet, the valve port is in a closed state under the action of the spring force and the residual air force of the valve body cavity. [0003] Currently on the market, the spring is assembled in the flow channel of the valve, and its working environment is the medium. This simple and compact structure is very suitable for conventional industrial control systems, but not suitable for high-temperature media. The high-...
