Description

Technical Field

[0001] The utility model belongs to the technical field of explosion-proof valves, in particular to a spring-type explosion-proof valve for pipe connection. Background Art

[0002] The principle of the explosion-proof valve is mainly to utilize its specific internal structure. When the internal pressure of the pressure vessel or pipeline exceeds the set value, the valve will automatically open to release the pressure, thereby preventing the container or pipeline from exploding. Specifically, the explosion-proof valve is usually composed of components such as a valve seat, a valve disc, a connecting rod and a spring. When the pressure in the container or pipeline rises, the valve disc will be lifted upward by the pressure, thereby opening the valve to release the pressure. When the pressure drops, the spring will push the valve disc downward and press it tightly, thereby closing the valve.

[0003] When there are impurities in the fluid, they tend to stay inside the valve body, so the fluid needs to be filtered. When the existing filter plate is used for a long time, too many impurities adhere to the surface of the filter plate, which will cause the filter plate to be blocked and the fluid cannot flow, making the filter plate unusable and unable to filter the fluid. The filter plate needs to be cleaned, and since the interior of the explosion-proof valve is relatively complicated, the disassembly process is time-consuming and laborious. Utility Model Content

[0004] The utility model aims to provide a spring-type explosion-proof valve for pipe connection, which provides a vibration component, specifically a connection rod rebounds to collide with the filter plate, and the filter plate is vibrated by the collision, and the impurities attached to the surface of the filter plate are dropped by the vibration, which will not affect the flow of the fluid, and the impurities can continue to be filtered, thereby extending the service life of the filter plate, thereby achieving the effect of reducing costs, and solving the problem that too many impurities attached to the surface of the existing filter plate will cause the filter plate to be blocked and the fluid cannot flow, making the filter plate unusable and unable to filter the fluid, and the filter plate needs to be cleaned. Since the interior of the explosion-proof valve is relatively complicated, the disassembly process is time-consuming and laborious.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a spring-type explosion-proof valve for pipe connection, comprising a pipeline body, a spring-type explosion-proof valve is arranged on the top of the pipeline body, a connecting ring is fixedly connected to the bottom of the spring-type explosion-proof valve, the bottom of the connecting ring is fixedly connected to the top of the pipeline body, a connecting block is fixedly connected to the left side of the connecting ring, a slide rail is fixedly connected to the left side of the connecting block, a push block is arranged on the left side of the connecting block, the right side of the push block is slidably connected to the outer surface of the slide rail, a flow hole is opened inside the connecting ring, a filter plate is rotatably connected to the inner wall of the flow hole, and a ring is fixedly connected to the inner wall of the flow hole;

A rotating hole is opened inside the connecting block, and a rotating rod is rotatably connected to the inner wall of the rotating hole. When the connecting rod moves upward, the extrusion plate is moved together, which will stretch the spring.

[0009] Furthermore, a connecting hole is provided inside the filter plate, the inner wall of the connecting hole is fixedly connected to the outer surface of the rotating rod, the back of the pushing block is fixedly connected to an insertion rod, and a plug hole is provided inside the rotating rod.

The vibration assembly 15 comprises a connecting rod 151, and an extrusion plate 153 is fixedly connected to the top of the connecting rod 151. The vibration assembly 15 is provided, specifically, the connecting rod 151 rebounds to collide with the filter plate 126, and the filter plate 126 is vibrated by the collision. Impurities attached to the surface of the filter plate 126 are removed by the vibration, which will not affect the flow of the fluid and can continue to filter the impurities, thereby extending the service life of the filter plate 126 and reducing the cost.

A rotating hole is provided inside the connecting block 12 , and a rotating rod 121 is rotatably connected to the inner wall of the rotating hole.

[0032] A connecting hole is provided inside the filter plate 126 , and the inner wall of the connecting hole is fixedly connected to the outer surface of the rotating rod 121 .

The right side of the clamping block 131 is clamped with the outer surface of the second fixing rod 128 .

[0037] A specific application of this embodiment is:

[0038] When in use, the fluid flows through the inside of the pipeline body 1, and the pressure generated during the flow is released through the spring-type explosion-proof valve 2. When the fluid enters the spring-type explosion-proof valve 2, it will pass through the filter plate 126 to filter impurities, so that the impurities will not adhere to the inside of the spring-type explosion-proof valve 2, thereby not affecting the pressure relief of the spring-type explosion-proof valve 2. When the spring-type explosion-proof valve 2 is inspected, the arc plate 13 is pulled to rotate on the surface of the fixed rod 1 127 to drive the block 131 to move away from the fixed rod 2 128. The block 131 is elastic, so the block 131 can be separated from the second fixing rod 128 smoothly, so that the arc plate 13 does not block the push block 123, and then the push block 123 is pulled to slide on the surface of the slide rail, driving the insertion rod 122 away from the inside of the rotating rod 121, so that the rotating rod 121 can rotate, and then the rotating rod 121 is rotated to drive the filter plate 126 to rotate back and forth, and it will collide with the connecting rod 151 during the rotation, so that the connecting rod 151 slides upward, driving the extrusion plate 153 to slide inside the sliding hole The squeezing plate 153 slides upward and stretches the spring 154. When the filter plate 126 rotates to the other side, the stretching force of the spring 154 disappears, and the connecting rod 151 rebounds and collides with the filter plate 126. The collision makes the filter plate 126 vibrate, and the impurities attached to the surface fall off, thereby extending the service life of the filter plate 126. After cleaning, the rotating rod 121 is rotated to align the insertion hole with the insertion rod 122, and then the pushing block 123 is pushed to insert the insertion rod 122 into the rotating rod 121. Inside, the rotating rod 121 is fixed so that the filter plate 126 will not be offset due to the influence of pressure, affecting the filtering effect, and then the arc plate 13 is rotated to drive the block 131 to approach the fixed rod 128. Since the block 131 is elastic, the block 131 can be smoothly stuck on the surface of the fixed rod 128, so that the arc plate 13 is fixed and can block the pushing block 123, so that the insertion rod 122 will not be separated from the inside of the socket due to vibration or other external factors, and the filter plate 126 will not be offset.
