Abstract
The invention provides a piston type fluid decompression mechanism. The piston type fluid decompression mechanism comprises a piston cylinder. A piston is arranged inside the piston cylinder. A valve port sealing gasket is arranged at the top end of the piston. A limiting structure is arranged between the sealing gasket and a valve port. The valve port sealing gasket is arranged at the top end of the piston. A first sealing ring and a second sealing ring are arranged on the side end face of the piston. A pressure adjusting spring is arranged at the position where the piston cylinder makes contact with the piston.
Description
Technical field
The present invention relates to fluid pressure valve technology field, be specifically related to a kind of plug flow mechanism of decompressor.
Background technique
In the existing piston type mechanism of decompressor, dynamic seal ring directly must bear the high-pressure of the front fluid of decompression, and component requirement on machining accuracy is high, and easily weares and teares under working state or bitten by sealed groove, thus reduction of service life; So need a kind of plug flow mechanism of decompressor badly to solve the problem.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of plug flow mechanism of decompressor, this plug flow mechanism of decompressor can solve the problem well.
For reaching above-mentioned requirements, the technological scheme that the present invention takes is: provide a kind of plug flow mechanism of decompressor, and this plug flow mechanism of decompressor comprises piston cylinder; Piston cylinder inside is provided with piston, and piston tip is provided with sealing valve port pad, the side end face of piston is provided with the first seal ring and the second seal ring; Piston cylinder and piston contact place are provided with pressure adjusting spring.
This plug flow mechanism of decompressor comprises piston cylinder, sealing valve port pad, piston, the first seal ring, pressure adjusting spring, the second seal ring, wherein sealing valve port pad and piston under the mating reaction of the first seal ring and the second seal ring, form the mechanism of decompressor with the valve port on piston cylinder, and determine post-decompression pressure by pressure adjusting spring; The dynamic seal ring of this plug flow mechanism of decompressor only need bear post-decompression hydrodynamic pressure, component machining accuracy can be reduced largely, and working state is lower because bearing pressure, effectively can reduces wearing and tearing and by the risk that sealed groove bites, increasing the service life.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present application, form a application's part, use identical reference number to represent same or analogous part in the drawings, the schematic description and description of the application, for explaining the application, does not form the improper restriction to the application.In the accompanying drawings:
Fig. 1 schematically shows the structural representation of the plug flow mechanism of decompressor according to the application embodiment.
Wherein: 1, piston cylinder; 2, sealing valve port pad; 3, piston; 4, the first seal ring; 5, pressure adjusting spring; 6, the second seal ring.
Embodiment
For making the object of the application, technological scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
In the following description, quoting of " embodiment ", " embodiment ", " example ", " example " etc. is shown that the embodiment of so description or example can comprise special characteristic, structure, characteristic, character, element or limit, but not each embodiment or example must comprise special characteristic, structure, characteristic, character, element or limit; In addition, reuse phrase " embodiment according to the application " although be likely refer to identical embodiment, and not necessarily refers to identical embodiment.
For the sake of simplicity, eliminate in below describing and well known to a person skilled in the art some technical characteristics.
According to an embodiment of the application, provide a kind of plug flow mechanism of decompressor, as shown in Figure 1, comprise piston cylinder 1; Described piston cylinder 1 inside is provided with piston 3, and described piston 3 top is provided with sealing valve port pad 2, the side end face of described piston 3 is provided with the first seal ring 4 and the second seal ring 6; Described piston cylinder 1 is provided with pressure adjusting spring 5 with described piston 3 contacting point.
According to an embodiment of the application, the piston cylinder 1 of this plug flow mechanism of decompressor is stainless steel structure.
According to an embodiment of the application, the piston 3 of this plug flow mechanism of decompressor is copper structure.
According to an embodiment of the application, being provided with between the sealing gasket 4 of this plug flow mechanism of decompressor and valve port for preventing gasket seal overcompression from wearing and tearing, ensureing the limit structure in the working life of whole mechanism.
According to an embodiment of the application, this plug flow mechanism of decompressor of this plug flow mechanism of decompressor comprises piston cylinder 1, sealing valve port pad 2, piston 3, first seal ring 4, pressure adjusting spring 5, second seal ring 6, wherein sealing valve port pad 2 and piston 3 under the mating reaction of the first seal ring 4 and the second seal ring 6, form the mechanism of decompressor with the valve port on piston cylinder 1, and determine post-decompression pressure by pressure adjusting spring 5; The dynamic seal ring of this plug flow mechanism of decompressor only need bear post-decompression hydrodynamic pressure, component machining accuracy can be reduced largely, and working state is lower because bearing pressure, effectively can reduces wearing and tearing and by the risk that sealed groove bites, increasing the service life.
The above embodiment only represents several mode of execution of the present invention, and it describes comparatively concrete and detailed, but can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to scope.Therefore protection scope of the present invention should be as the criterion with described claim.
