Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a full-volume safety valve which is convenient to adjust. Background Art

[0002] Safety valves are special valves that are normally closed when an external force is applied to the opening and closing parts. When the pressure of the medium in the equipment or pipeline exceeds the specified value, the medium is discharged to the outside of the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves are automatic valves and are mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value, playing an important protective role in personal safety and equipment operation.

[0003] A Chinese patent with the search announcement number CN203783609U discloses a remotely visible large flow pressure display memory type safety valve, which can not only meet and adapt to the instantaneous high pressure impact and rapid large flow unloading, but also can display and record the changes in the support working pressure at any time. Within an appropriate range, the safety support status of the hydraulic pressure can be observed from a distance even in an environment with insufficient light.

[0004] However, this remotely visible large-flow pressure-displaying memory safety valve cannot adjust the pressure relief flow, resulting in low practicality of the device. Utility Model Content

This arrangement can improve the pressure relief effect of the device. The first spring 26 is fixedly connected to one side of the first connecting plate 21, and the other end of the first spring 26 is fixedly connected to the second connecting plate 22 A lifting assembly 4 is provided in the valve body 1, and the lifting assembly 4 includes a threaded rod 41, which is rotatably connected to the top of the inner cavity of the valve body 1 through a bearing, and one end of the threaded rod 41 is fixedly connected to a turning handle 42, and the turning handle 42 is provided with an anti-slip thread. In this way, the rotation of the threaded rod 41 can be controlled by the turning handle 42, and hand slip can be prevented. A third connecting plate 43 is threadedly connected to the threaded rod 41, and both sides of the third connecting plate 43 are fixedly connected to a limiting block 46, and the limiting block 46 is slidably connected to both sides of the inner cavity of the valve body 1. The limiting block 46 can limit the third connecting plate 43 to prevent the third connecting plate 43 from rotating and preventing the third connecting plate 43 from shaking during movement. Fixed plates 44 are fixedly connected to both sides of the inner cavity of the valve body 1, and the fixed plates 44 are rotatably connected to the threaded rod 41 through a bearing, and a first connecting rod 45 is fixedly connected to the bottom of the third connecting plate 43, and the first connecting rod 45 is fixedly connected to the second connecting plate 22.

[0030] Specifically, the third connecting plate 43 is fixedly connected to the limiting blocks 46 on both sides, and the limiting blocks 46 are slidably connected to the two sides of the inner cavity of the valve body 1.
