[0003] The current one-way valve basically does not have fire-resistant performance, and in the event of a fire, it often causes liquid or gas leakage in the pipeline, resulting in loss and pollution
Moreover, the current one-way valves still have problems such as easy damage, easy corrosion, and low strength.

Abstract
The invention relates a machining process of a high strength fire-resistant one-way valve, and belongs to the technical field of valve devices. The machining process of the high strength fire-resistant one-way valve includes the following steps that (1), material batching is conducted; (2), raw material smelting is conducted; (3), cooling of alloy solution made in the last step and formation of alloy are conducted; (4), secondary smelting of the alloy made in the last step in the smelter and formation of the alloy solution are conducted; (5), forging is conducted; (6), carburizing process is conducted; (7), quenching is conducted; (8), tempering is conducted; (9), grinding and polishing of a valve body are conducted; (10), the surface of the valve body is varnished by fire retardant coating; and (11), a valve plug is put into the valve body varnished with the fire retardant coating, and the high strength fire-resistant one-way valve is produced. The machining process of the high strength fire-resistant one-way valve improves the mechanical strength and the fire resistance performance of the high strength fire-resistant one-way valve through heat treatment process and varnishing ofthe fire retardant coating, and loss and pollution caused by liquid or gas leakage from a pipeline can be prevented when the fire happens.
Description
technical field [0001] The invention relates to a processing technology of a high-strength fire-resistant one-way valve, which belongs to the technical field of valve equipment. Background technique [0002] The one-way valve is that the fluid can only flow along the water inlet, but the outlet medium cannot flow back, commonly known as a one-way valve. One-way valve is also called check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air. There are two types of check valves, straight-through and right-angle. The straight-through check valve is installed on the pipeline with a threaded connection. There are three types of right-angle check valves: threaded connection, plate connection and flange connection. The hydraulic control check valve is also called a lock valve or a pressure maintaining valve. It is the same as a check valve and is used to prevent the reverse fl...
