Description

Technical Field

[0001] This utility model relates to the field of drain valve technology, and in particular to a drain valve device with pressure relief function. Background Technology

[0002] A drain valve is a type of valve used to discharge liquids or gases. It is commonly found in pipeline systems, pressure vessels, or equipment maintenance. Its main function is to safely drain media (such as water, oil, condensate, etc.). The existing drain valve device has the following drawbacks when in use: Existing drain valve devices typically do not have a pressure relief function. The pressure inside the pipeline cannot be relieved in time through the drain valve, which can easily cause the pipeline to burst. A small number of devices do have a pressure relief function, but the springs inside the pressure relief components and the drain valve weaken their rebound performance after long-term use, making them prone to air leakage and water leakage. If the springs cannot be replaced, the entire drain valve must be replaced, which will increase the cost of use. Utility Model Content

[0003] In view of the technical problems in the prior art, the existing drain valve devices usually do not have a pressure relief function. The pressure inside the pipeline cannot be relieved in time through the drain valve, which can easily cause the pipeline to burst. A small number of them have a pressure relief function, but the spring inside the pressure relief component and the spring inside the drain valve have weakened rebound performance after long-term use. If the spring cannot be replaced, the entire drain valve must be replaced, which will increase the operating cost. This utility model provides a drain valve device with a pressure relief function.

[0004] The technical solution adopted by this utility model is: a drain valve device with pressure relief function, including a drain valve body, a pressure relief pipe provided on the drain valve body, and replacement components provided at one end of the pressure relief pipe and the top end of the drain valve body. The replacement components include a ring, a fixing box, and slots. The top end of the drain valve body and one end of the pressure relief pipe both pass through the ring. The fixing box is fixedly mounted on the outer wall of the ring, and a plug is slidably connected inside the fixing box. Several slots are respectively opened on the outer wall of the top end of the drain valve body and one end of the pressure relief pipe. The insert block is inserted into the slot. A pull block is fixedly installed on the outer wall of one side of the insert block, and the pull block extends to the outside of the fixing box. A fixing spring connected to the insert block is installed on the inner wall of the fixing box. The fixing spring is sleeved on the outside of the pull block. A baffle is installed inside the pressure relief pipe, and a sealing ring that fits against the inner wall of the pressure relief pipe is installed on the outer wall of the baffle. A guide rod extending to the outside of the pressure relief pipe is installed on the outer wall of the baffle. A pressure relief spring connected to the guide rod is installed on the inner wall of the pressure relief pipe. An exhaust pipe is installed on the outer wall of the top of the pressure relief pipe.

[0005] Furthermore, the drain valve body is equipped with an anti-clogging component, which includes a filter screen, a support rod, and a support base. The filter screen is fixedly installed on the inner wall of the drain valve body.

[0006] Furthermore, the support rod is fixedly installed on the inner wall of the drain valve body, and the support seat is fixedly installed at the other end of the support rod away from the inner wall of the drain valve body.

[0007] Furthermore, a rotating rod is rotatably inserted through the interior of the support base via a bearing, and several swirl blades are fixedly installed at the bottom end of the rotating rod.

[0008] Furthermore, a cleaning brush is fixedly installed at the top of the rotating rod, and the cleaning brush is in contact with the filter screen.

[0009] Furthermore, a water outlet pipe is fixedly installed on the outer wall of one side of the drain valve body, and a sealing block is slidably connected inside the drain valve body.

[0010] Furthermore, a sealing seat is provided on the inner wall of the drain valve body, and a sealing block is engaged inside the sealing seat. A drain spring connected to the sealing block is provided on the inner wall of the top of the drain valve body.

[0011] The beneficial effects of this utility model are: This invention allows for easy separation of the ring from the drain valve body and pressure relief pipe by replacing components, facilitating the disassembly and replacement of the drain spring and pressure relief spring. When the rebound performance of the drain spring and pressure relief spring weakens after long-term use, only the drain spring and pressure relief spring need to be replaced, without replacing the entire drain valve, thus reducing operating costs.

[0012] Secondly, this utility model uses an anti-clogging component. The filter screen can filter the water and prevent impurities from clogging the inside of the drain valve. When water enters the drain valve body, it impacts the swirl vanes, which drive the rotating rod and cleaning brush to rotate, thus cleaning the impurities off the filter screen and achieving the anti-clogging function.

[0017] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0018] In order to solve the problems existing in the background art, this application proposes the following technical solution: a water discharge valve device with pressure relief function.

[0019] The specific technical solution includes a drain valve body 1, on which a pressure relief pipe 2 is provided. Replacement components 3 are provided at one end of the pressure relief pipe 2 and at the top of the drain valve body 1. The replacement components 3 include a ring 301, a fixing box 302, and a slot 304. The top of the drain valve body 1 and one end of the pressure relief pipe 2 both pass through the ring 301. The fixing box 302 is fixedly mounted on the outer wall of the ring 301. An insert block 303 is slidably connected inside the fixing box 302. Several slots 304 are respectively opened on the outer wall of the top of the drain valve body 1 and one end of the pressure relief pipe 2, and the insert block 303 is inserted into the inside of the slot 304. A pull block 305 is fixedly mounted on the outer wall of one side of the insert block 303. 5 extends to the outside of the fixing box 302. The inner wall of the fixing box 302 is provided with a fixing spring 306 connected to the insert block 303. The fixing spring 306 is sleeved on the outside of the pull block 305. The inside of the pressure relief pipe 2 is provided with a baffle 9. The outer wall of the baffle 9 is provided with a sealing ring 10 that fits against the inner wall of the pressure relief pipe 2. The outer wall of the baffle 9 is provided with a guide rod 11 extending to the outside of the pressure relief pipe 2. The inner wall of the pressure relief pipe 2 is provided with a pressure relief spring 13 connected to the guide rod 11. The outer wall of the top of the pressure relief pipe 2 is provided with an exhaust pipe 12. The replacement component 3 is used to replace the water discharge spring 8 and the pressure relief spring 13 whose rebound force has weakened. It is not necessary to replace the entire water discharge valve body 1, which can reduce the cost of use.

[0020] In specific implementations, such as Figure 2 As shown, the inside of the drain valve body 1 is provided with an anti-clogging component 4. The anti-clogging component 4 includes a filter screen 401, a support rod 402 and a support base 403. The filter screen 401 is fixedly installed on the inner wall of the drain valve body 1. The anti-clogging component 4 is used to filter impurities in the water.

[0021] Furthermore, the support rod 402 is fixedly installed on the inner wall of the drain valve body 1, and the support seat 403 is fixedly installed at the other end of the support rod 402 away from the inner wall of the drain valve body 1. The support rod 402 is used to support the rotating rod 404.

[0022] Furthermore, a rotating rod 404 is rotatably inserted through the interior of the support base 403 via a bearing, and several swirling blades 406 are fixedly installed at the bottom end of the rotating rod 404. When the swirling blades 406 rotate, they will drive the rotating rod 404 to rotate.

[0023] Furthermore, a cleaning brush 405 is fixedly installed at the top of the rotating rod 404, and the cleaning brush 405 is in contact with the filter screen 401. The cleaning brush 405 can clean the impurities on the filter screen 401 and prevent the filter screen 401 from becoming clogged.

[0024] In specific implementations, such as Figure 1 and Figure 2As shown, a water outlet pipe 5 is fixedly installed on the outer wall of one side of the water outlet valve body 1, and a sealing block 6 is slidably connected inside the water outlet valve body 1. The water outlet pipe 5 is used for water discharge.

[0025] In specific implementations, such as Figure 2 As shown, a sealing seat 7 is provided on the inner wall of the drain valve body 1, and a sealing block 6 is engaged inside the sealing seat 7. A drain spring 8 connected to the sealing block 6 is provided on the inner wall of the top of the drain valve body 1. The elastic force of the drain spring 8 can push the drain spring 8 to move back.

[0026] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: When in use, if there is pressure inside the pipe connected to the waterproof valve, the pressure will first push the baffle 9 to move, and the vent pipe 12 will release the pressure. After the pressure is released, the pressure relief spring 13 pushes the baffle 9 back to block the vent pipe 12. After the pressure is released, water will enter the drain valve body 1. The filter screen 401 can filter impurities in the water. When the water enters the drain valve body 1, it will impact the vortex vane 406, which will cause the vortex vane 406 to drive the rotating rod 404 and the cleaning brush 405 to rotate. The cleaning brush 405 can clean the impurities on the filter screen 401. The water will push the sealing block 6 to move, and the water will be discharged through the outlet pipe 5. When the water is discharged... After prolonged use, the rebound force of the pressure relief spring 13 and the drain spring 8 in valve body 1 will weaken, making them prone to air and water leakage. Pulling the pull block 305 on the pressure relief pipe 2 will move the insert block 303 out of the slot 304, allowing the ring 301 to separate from the pressure relief pipe 2. This makes it easy to remove and replace the pressure relief spring 13 from the pressure relief pipe 2. Similarly, pulling the pull block 305 on the drain valve body 1 will move the insert block 303 out of the slot 304, allowing the ring 301 to separate from the drain valve body 1. This makes it easy to remove and replace the pressure relief spring 13 from the drain valve body 1, eliminating the need to replace the entire drain valve body 1 and reducing operating costs.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
