Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure relief safety valve technology, and in particular to a pressure relief safety valve for fluid pipeline transportation. Background Technology
[0002] A pressure relief safety valve is a safety device used in containers, pipelines, and equipment. Its main function is to automatically release overpressure to prevent the pressure in the system from exceeding the safe range, which could lead to equipment damage and accidents, thereby ensuring the safe operation of the system.
[0003] In the prior art, pressure relief safety valves typically release excess medium from the pipeline, thereby reducing the pressure inside the pipeline. When the pressure inside the fluid pipeline is too high, the pressure relief safety valve releases excess fluid from the pipeline to reduce the fluid pressure inside the pipeline. The fluid released through pressure relief will be discharged out of the pipeline. At this time, the fluid can no longer flow through the pipeline to the area where the fluid is needed, thus causing a waste of fluid resources. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art where fluid released through pressure relief is discharged outside the pipeline, and the fluid can no longer flow through the pipeline to the area where the fluid is needed, thus causing a waste of fluid resources. Therefore, this invention proposes a pressure relief safety valve for fluid pipeline transportation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure relief safety valve for fluid pipeline transportation, comprising: a first pipeline, a second pipeline fixedly connected to the outer surface of the first pipeline, a third pipeline fixedly connected to the outer surface of the second pipeline, a conveying assembly disposed inside the third pipeline, the conveying assembly comprising a motor, an output shaft fixedly connected to the output end of the motor, a turntable fixedly connected to one end of the outer surface of the output shaft, a fixed disk rotatably connected to one end of the output shaft, and two grooves formed on the outer surface of the fixed disk.
[0006] Preferably, the outer surface of the turntable is in contact with the outer surface of the fixed plate, and a fixing plate is fixedly connected to the inner wall of the third pipe near one end.
[0007] Preferably, the motor is mounted on the outer surface of the fixed plate, and a protective box is fixedly connected to the outer surface of the fixed plate.
[0008] Preferably, the motor is located inside the protective housing, and the outer surface of the output shaft is in contact with the inner wall of the protective housing.
[0009] Preferably, a valve seat is fixedly connected to the inner wall of the second pipe, and a valve disc is attached to the outer surface of the valve seat.
[0010] Preferably, a spring is provided on the outer surface of the valve disc, one end of the spring is fixedly connected to the outer surface of the valve disc, and the other end of the spring is fixedly connected to the inner wall of the second pipe.
[0011] Preferably, a pressure gauge is provided on the outer surface of the first pipe, a fourth pipe is fixedly connected to the outer surface of the third pipe, one end of the fourth pipe is connected to the outer surface of the first pipe, the outer surface of the fixed plate is fixedly connected to the inner wall of the fourth pipe, and the outer surface of the turntable is in contact with the inner wall of the fourth pipe.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, the device is equipped with a third pipe and a conveying component. When pressure is released, the fluid will flow into the third pipe through the second pipe, and then into the fourth pipe through the third pipe. When the fluid in the first pipe decreases, the fluid in the fourth pipe can be returned to the first pipe by rotating the turntable. This ensures that the fluid released by pressure relief will flow back into the first pipe, and the fluid will then flow through the first pipe to the area where the fluid is needed, thereby ensuring the effective use of fluid resources.
[0014] 2. In this utility model, the device protects the motor by installing a protective box around the motor. When the fluid is in the third pipeline, the protective box can prevent the fluid from directly corroding and wearing the motor, thereby extending the service life of the motor.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1: As Figures 1-7 As shown, this utility model provides a pressure relief safety valve for fluid pipeline transportation, including a first pipeline 1, a second pipeline 2 fixedly connected to the outer surface of the first pipeline 1, a third pipeline 3 fixedly connected to the outer surface of the second pipeline 2, and a conveying assembly 4 disposed inside the third pipeline 3. The conveying assembly 4 includes a motor 401, an output shaft 402 fixedly connected to the output end of the motor 401, a turntable 403 fixedly connected to one end of the outer surface of the output shaft 402, and a fixed disk 404 rotatably connected to one end of the output shaft 402. Two grooves 405 are formed on the outer surface of the fixed disk 404, and the outer surface of the turntable 403 fits against the outer surface of the fixed disk 404. A fixing plate 5 is fixedly connected to the inner wall of the third pipe 3 near one end. A valve seat 7 is fixedly connected to the inner wall of the second pipe 2. A valve disc 8 is attached to the outer surface of the valve seat 7. A spring 9 is provided on the outer surface of the valve disc 8. One end of the spring 9 is fixedly connected to the outer surface of the valve disc 8, and the other end of the spring 9 is fixedly connected to the inner wall of the second pipe 2. A pressure gauge 10 is provided on the outer surface of the first pipe 1. A fourth pipe 11 is fixedly connected to the outer surface of the third pipe 3. One end of the fourth pipe 11 is connected to the outer surface of the first pipe 1. The outer surface of the fixing plate 404 is fixedly connected to the inner wall of the fourth pipe 11. The outer surface of the turntable 403 is attached to the inner wall of the fourth pipe 11.
[0026] The overall effect of Embodiment 1 is that, when a pressure relief safety valve for fluid pipeline transportation is in use, fluid flows inside the first pipeline 1. When the pressure inside the first pipeline 1 is too high, the pressure gauge 10 will detect that the fluid pressure inside the first pipeline 1 is too high. The fluid will flow into the valve seat 7 and contact the outer surface of the valve disc 8. When the fluid pressure is too high, the fluid pressure will push the valve disc 8 to move, pushing the valve disc 8 towards the spring 9 and squeezing the spring 9 until the valve disc 8 no longer contacts the outer surface of the valve seat 7. When the fluid is touched, it flows through the inner wall of the valve seat 7 into the second pipe 2. The fluid in the first pipe 1 flows into the second pipe 2, gradually reducing the pressure in the first pipe 1. At this time, the pressure of the fluid on the valve disc 8 also gradually decreases. The elastic force of the spring 9 moves the valve disc 8 towards the valve seat 7 until the outer surface of the valve disc 8 is in contact with the outer surface of the valve seat 7. Then, the fluid in the second pipe 2 flows into the third pipe 3, and then along the third pipe 3 into the fourth pipe 11. When the fluid in the first pipe 1 is not completely... When the inner walls of the first pipe 1 come into contact with each other, there is space in the first pipe 1 to store fluid. The operator can start the motor 401, which will drive the output shaft 402 to rotate. The output shaft 402 will drive the turntable 403 to rotate. The outer surface of the turntable 403 will rotate in contact with the fourth pipe 11 and the fixed plate 404 until the outer surface of the turntable 403 is no longer on the two grooves 405 in the fixed plate 404. At this time, the motor 401 will be stopped. The fluid in the fourth pipe 11 will flow back into the first pipe 1 through the two grooves 405 and then flow along the first pipe... The fluid flows from pipe 1 to the area where it is needed. By setting up a third pipe 3 and a conveying component 4, when pressure is released, the fluid will flow from the second pipe 2 into the third pipe 3, and then from the third pipe 3 into the fourth pipe 11. When the fluid in the first pipe 1 decreases, the fluid in the fourth pipe 11 can be returned to the first pipe 1 by rotating the turntable 403. This solves the problem that the fluid released by pressure relief will be discharged out of the pipe, and at this time the fluid can no longer flow through the pipe to the area where the fluid is needed, thus causing a waste of fluid resources.
[0027] Example 2: Figures 1-7 As shown, the motor 401 is mounted on the outer surface of the fixed plate 5, and the protective box 6 is fixedly connected to the outer surface of the fixed plate 5. The motor 401 is mounted inside the protective box 6, and the outer surface of the output shaft 402 is in contact with the inner wall of the protective box 6.
[0028] The effect achieved by the entire embodiment 2 is that, when a pressure relief safety valve for fluid pipeline transportation is in use, when pressure is released, the fluid flows from the first pipeline 1 into the second pipeline 2, and then from the second pipeline 2 into the third pipeline 3. The fluid passes through the outer surface of the protective box 6, which is fitted onto the outer surface of the motor 401. Thus, when the fluid is in the third pipeline 3, it can effectively prevent the fluid from directly contacting the motor 401, thereby ensuring that the motor 401 will not be corroded or worn by the fluid, and thus extending the service life of the motor 401.
[0029] Working Principle: When a pressure relief safety valve for fluid pipeline transportation is in use, if the internal pressure of the first pipeline 1 is too high, the fluid will push the valve disc 8 to move until the valve disc 8 no longer contacts the outer surface of the valve seat 7. The fluid will then flow through the inner wall of the valve seat 7 into the second pipeline 2, gradually reducing the pressure in the first pipeline 1. The elastic force of the spring 9 will move the valve disc 8 towards the valve seat 7 until the outer surface of the valve disc 8 is in contact with the outer surface of the valve seat 7. At this time, the fluid in the second pipeline 2 will flow into the third pipeline 3. In the third pipeline 3, the fluid will pass through the outer surface of the protective box 6, which is fitted onto the outer surface of the motor 401. This effectively prevents the fluid from directly contacting the motor 401. The fluid then flows through the third pipeline 3 into the fourth pipeline 11. If there is space in the first pipeline 1... For fluid, the operator can start the motor 401, which will drive the output shaft 402 to rotate. The output shaft 402 will drive the turntable 403 to rotate until the outer surface of the turntable 403 is no longer on the two grooves 405. At this time, the fluid in the fourth pipe 11 will flow back into the first pipe 1 through the two grooves 405. By setting the third pipe 3 and the conveying component 4, when pressure is released, the fluid will flow into the third pipe 3 through the second pipe 2, and then into the fourth pipe 11 through the third pipe 3. When the fluid in the first pipe 1 decreases, the turntable 403 can be rotated to allow the fluid in the fourth pipe 11 to flow back into the first pipe 1. This ensures that the fluid released by pressure relief will flow back into the first pipe 1, and the fluid will then flow through the first pipe 1 to the area where the fluid is needed, thus ensuring the effective use of fluid resources.
[0030] This safety valve can be applied to a variety of fluid transportation applications, especially those involving fluid transport.
