Abstract
The utility model discloses a pressure relief valve with adjustable set pressure. The pressure relief valve comprises a pipeline connecting body and a movable plunger. The movable plunger and the pipeline connecting body are connected in a sliding mode. The pipeline connecting body comprises an inlet flange and an outlet flange. The pressure relief valve further comprises a support lug and a lever. One end of the lever is connected with the support lug in a rotating mode. The top end of the movable plunger is a hemispherical structure. The lever is connected with the movable plunger in a sliding mode. The pressure relief valve with the adjustable set pressure has the advantages that a spring and the lever is placed, the set pressure of the pressure relief valve can be adjusted by changing springs with different specifications, and therefore return speed of the plunger is fast and damage of working medium is small.
Description
Technical field
The utility model relates to a kind of Decompression valves, more precisely the adjustable Decompression valves of a kind of Set pressure.
Background technique
Adopt the Set pressure of balancing weight adjusting pressure release valve in the Decompression valves of the prior art, but when pressure surge was larger in the pipeline, may not can the timely return of balancing weight caused working medium to run off, perhaps inflammable and explosive if working medium is toxic, harm is just larger.
The model utility content
The utility model mainly is to solve the existing technical problem of prior art, thereby provide a kind of with spring and lever, can come by the spring of changing different size the Set pressure of adjusting pressure release valve, make simultaneously the return speed of plunger, the adjustable Decompression valves of Set pressure that medium-loss is less.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The adjustable Decompression valves of a kind of Set pressure, described Decompression valves comprises a pipeline connecting body and a movable plunger, described movable plunger and described pipeline connecting body are slidingly connected, described pipeline connecting body comprises an inlet flange and an outlet(discharge) flange, described Decompression valves also comprises a journal stirrup and a lever, one end and the described journal stirrup of described lever are rotationally connected, and the top of described movable plunger is hemispherical dome structure, and described lever and described movable plunger are slidingly connected.
As the utility model preferred embodiment, described Decompression valves also comprises a spring, and the upper end of described spring is connected with the other end of described lever.
As the utility model preferred embodiment, described Decompression valves also comprises a fixed plate, and described fixed plate is connected with the lower end of described spring.
Therefore the advantage of the adjustable Decompression valves of Set pressure of the present utility model is, with spring and lever, can come by the spring of changing different size the Set pressure of adjusting pressure release valve, makes simultaneously the return speed of plunger, and medium-loss is less.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
It is a kind of with spring and lever that the utility model provides, and can come by the spring of changing different size the Set pressure of adjusting pressure release valve, makes simultaneously the return speed of plunger, the adjustable Decompression valves of Set pressure that medium-loss is less.
As shown in Figure 1 and Figure 2, the adjustable Decompression valves of a kind of Set pressure, this Decompression valves comprises a pipeline connecting body 1 and a movable plunger 2, this movable plunger 2 is slidingly connected with this pipeline connecting body 1, this pipeline connecting body 1 comprises an inlet flange 11 and an outlet(discharge) flange 12, and this Decompression valves also comprises a journal stirrup 3 and a lever 4, and an end and this journal stirrup 3 of this lever 4 are rotationally connected, the top of this movable plunger 2 is hemispherical dome structure, and this lever 4 is slidingly connected with this movable plunger 2.
This Decompression valves also comprises a spring 6, and the upper end of this spring 6 is connected with the other end of this lever 4.
This Decompression valves also comprises a fixed plate 5, and this fixed plate 5 is connected with the lower end of this spring 6.
Below only with a mode of execution mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to simultaneously external more function module, thereby expands to greatest extent its function.
The above only be embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
