Description

Technical Field

[0001] The utility model relates to the technical field of safety valve devices, in particular to a safety valve used in oil and gas storage and transportation projects. Background Art

[0002] The safety valve plays a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve opens and discharges part of the gas or fluid in the system into the atmosphere or outside the pipeline, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause accidents due to excessive pressure. It is mainly used in boilers, pressure vessels and pipelines.

[0003] At present, the existing utility model has an adjusting groove at the top of the valve body, and the inside of the adjusting groove is processed with threads. The adjusting ring is installed in the adjusting groove through the threads. When the operator rotates the part of the adjusting ring exposed outside the valve body, the adjusting ring can be moved up and down in the adjusting groove for adjustment. In this way, the force of the compression spring can be controlled by the pressure plate at the bottom of the adjusting ring to control the pressure of the spring on the plug body. The greater the pressure, the better the sealing effect, thereby realizing the adjustability of the safety valve to the plug body.

[0004] For example, a highly airtight oil and gas pipeline safety valve disclosed in the authorization number CN215293754U includes an interface, a valve body and an outlet. The bottom end of the valve body is fixed with an interface, one side of the valve body is fixed with an outlet, and the top end of the valve body is provided with an adjustment structure, which includes a pressure plate, an adjustment groove and an adjustment ring. The adjustment groove is provided at the top end of the valve body, and an adjustment ring is provided inside the adjustment groove. A pressure plate is fixed at the bottom end of the adjustment ring, and a plug body is provided at the bottom end of the valve body. Both sides of the plug body are provided with a guide structure, and a protective structure is provided at the top end of the plug body. A straight rod is fixed at the center position of the top end of the plug body, and a spring is provided on the surface of the straight rod. However, for such a highly airtight oil and gas pipeline safety valve, it is unclear how to facilitate the pipeline docking installation of the safety valve, and it is inconvenient for the operator to release the pressure of the safety valve in time.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is unclear how to facilitate the pipe docking installation of the safety valve, and it is inconvenient for the operator to release the pressure of the safety valve in time. Therefore, it is necessary to improve the existing technology. Utility Model Content
