Description
Technical Field
The utility model relates to a hydraulic valve technology, in particular to a check valve easy to install and assemble.
Background
Check valve in the current hydrovalve includes the check valve casing, a spring, the inlet and outlet connects, the gasket, spring holder isotructure, structural design is comparatively complicated, current check valve carries out threaded connection or flange joint as solitary part and business turn over pipeline simultaneously, threaded connection department still need adopt the sealing washer with flange joint department, paint mode such as sealed glue and seal, still need the bolt to fix the check valve, consequently, the installation and the change of check valve are all more troublesome, when the check valve is applied to the more complicated operational environment of vibrations environment, there is threaded connection and appears the pine easily and take off, the problem of revealing.
Disclosure of Invention
In order to solve the problems that the check valve in the prior art is troublesome to install and replace and is easy to loosen and leak when applied to a vibration working environment, the utility model provides the check valve which is easy to install and assemble. The utility model relates to a check valve easy to install and assemble, which is characterized in that: the sealing piece is in contact with the upper end face of the valve seat, the upper end face of the sealing piece is in contact with the lower end face of the gasket, the sealing piece and the gasket are provided with through holes, the spring seat is a post rod with one head at one end, the rod end of the spring seat penetrates through the gasket, the sealing piece and the spring seat mounting hole of the valve seat and is riveted on the valve seat, and the spring is sleeved on the post rod of the spring seat and is arranged between the lower end of the head of the spring seat and the upper end face of the gasket.
Furthermore, the lower end of the head of the spring seat is provided with a groove for mounting the spring.
Compared with the prior art, the utility model has the following beneficial effects:
according to the check valve easy to install and assemble, the valve seat is installed in a pipeline where a medium flows in an interference fit mode, when the medium flows, the medium pushes the sealing sheet and the gasket to move upwards and compress the spring at the same time, and the medium flows normally through the flow passage in the valve seat; when the medium is stopped, the medium and the spring push the gasket and the sealing sheet to move downwards together, and the sealing sheet is tightly contacted with the valve seat to form a seal so as to prevent the medium from flowing in the channel. Therefore, the check valve does not need a special check valve shell, the related parts have simple structures, can be directly manufactured by stamping, are convenient to assemble, and reduce the overall cost of the parts; the check valve can be directly installed in a pipeline for medium flowing, is convenient to install, is hidden in the pipeline after being installed, and is concise in appearance without any exposure. The check valve does not need threaded connection or flange connection, sealant is coated, and the risk of medium leakage can be thoroughly avoided.

In the figure: 1. the valve comprises a valve seat, 2 sealing pieces, 3 gaskets, 4 springs, 5 spring seats and 6 pipelines.
Detailed Description
The purpose, technical scheme and beneficial effects of the utility model are further described in detail in the following with reference to the accompanying drawings. It should be understood that the embodiments described herein are illustrative only and are not limiting, since any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
Fig. 1 is an easy-to-install check valve of the present invention, characterized in that: the sealing piece comprises a valve seat 1, a sealing piece 2, a gasket 3, a spring 4 and a spring seat 5, wherein the valve seat 1 is a cylinder provided with a medium circulation channel and a spring seat mounting hole, the lower end face of the sealing piece 2 is contacted with the upper end face of the valve seat 1, the upper end face of the sealing piece 2 is contacted with the lower end face of the gasket 3, the sealing piece 2 and the gasket 3 are provided with through holes, the spring seat 5 is a post rod with a head at one end, the rod end of the spring seat 5 penetrates through the gasket 3, the sealing piece 2 and the spring seat mounting hole of the valve seat 1 to be riveted on the valve seat 1, and the spring 4 is sleeved on the post rod of the spring seat 5 and is arranged between the lower end of the head of the spring seat 5 and the upper end face of the gasket 3.
Fig. 2 shows an embodiment of the valve seat 1 of the check valve easy to install and assemble according to the present invention, the valve seat 1 is provided with a spring seat mounting hole in the middle, and a medium flow passage is provided at the periphery of the spring seat mounting hole.
Fig. 3 shows an embodiment of the spring seat 5 of the check valve of the present invention, which is easy to install and assemble, and the lower end of the head of the spring seat 5 is provided with a groove for installing the spring 4.
Fig. 4 is a schematic diagram of the installation and use of the check valve of the present invention, which is easy to install and assemble, when in flow, the medium pushes the sealing plate 2 and the gasket 3 to move upwards while compressing the spring 4, the medium normally flows through the flow passage on the valve seat 1, and the spring seat 5 serves to limit the movement range; when the valve is stopped, the medium and the spring 4 push the gasket 3 and the sealing plate 2 to move downwards together, and the sealing plate 2 is tightly contacted with the valve seat 1 to form a seal so as to prevent the medium from flowing in the channel.
