Description

Technical Field

[0001] This invention relates to the field of high-pressure pipe fitting technology, specifically a high-pressure pipe fitting seal. Background Technology

[0002] With the continuous development of pipelines and the widespread application of non-metallic high-pressure pipelines, the technical requirements for high-pressure straight pipe joints are becoming increasingly stringent. This is because high-pressure straight pipe joints are the core components of pipelines transporting high-pressure liquids, and they directly affect the performance and quality of these pipelines. Pipe joints are used to connect two pipes of a certain length through their two end interfaces, allowing the two pipes to communicate with each other and enabling the connected pipes to transport gases, liquids, or fluids containing solid particles.

[0003] Currently, most pipe connectors are installed by connecting to the pipes through threads at both ends. While this method can complete the installation, the active or passive rotation of the threads at both ends takes a considerable amount of time. Furthermore, although existing locking pipe connectors can quickly connect to the pipes, the locking handle is prone to turning back due to thermal expansion and contraction, leading to reduced connection tightness and leakage. Moreover, pipe connectors with good locking performance require damage to the locking structure during removal, making them difficult to recycle and reuse. Therefore, we propose a high-pressure pipe joint seal. Summary of the Invention

[0005] This invention provides the following technical solution: a high-pressure pipe joint seal, comprising a water pipe joint body, a connector fixedly mounted on the outer edge of the water pipe joint body, a round tube fixedly mounted on the side of the connector away from the water pipe joint body, a contact plate fixedly mounted on the side of the round tube away from the connector, and a connecting tube fixedly mounted on the side of the round tube away from the round tube, a retaining ring fixedly mounted on the outer edge of the connecting tube, a sealing ring sleeved on the outer edge of the connecting tube, a water nozzle fixedly mounted on the end of the connecting tube away from the contact plate, a corrosion-resistant layer embedded in the inner cavity of the water pipe joint body, a fixing tube fixedly mounted on the outer edge of the water pipe joint body, a warning light fixedly mounted on the end of the fixing tube away from the water pipe joint body, a first diaphragm fixedly mounted on the inner wall of the fixing tube, an electromagnetic plate fixedly mounted on the top of the first diaphragm, a second diaphragm fixedly mounted on the inner wall of the fixing tube, one end of a fixing rod fixedly connected to the top of the inner wall of the fixing tube, a fixing plate fixedly mounted on the other end of the fixing rod, and a spring fixedly mounted on the bottom of the fixing plate.

[0006] Preferably, the outer edge of the water pipe connector body is provided with a through hole, the through hole and the connector are positioned correspondingly, and the left side of the connector is tightly fitted and fixedly connected to the inner wall diameter of the through hole.

[0007] Preferably, the inner wall of the second tympanic membrane is provided with a buffer block, and the buffer block is fixedly connected to the end of the spring away from the fixing plate.

[0008] Preferably, the first tympanic membrane is elastic, and an electromagnetic plate is also fixedly mounted on the arc surface of the second tympanic membrane, with the electromagnetic plate on the top of the first tympanic membrane corresponding to the electromagnetic plate on the arc surface of the second tympanic membrane.

[0009] Preferably, a controller is provided on the inner wall of the water pipe connector body, and the warning light, the controller and the electromagnetic plate are electrically connected.

[0010] Preferably, the outer edge of the water pipe connector body is provided with a circular hole, and the circular hole and the through hole are arranged opposite to each other, and the end of the fixing pipe away from the warning light is closely fitted with the inner wall of the circular hole.

[0011] Preferably, there are four retaining rings, which are distributed in parallel along the outer edge of the connecting pipe. The sealing ring is located between the bottom retaining ring and the water nozzle, and the sealing ring is made of rubber.

[0013] Preferably, the outer diameters of the first and second tympanic membranes are both adapted to the inner wall diameter of the fixed tube, the distance between the first and second tympanic membranes is 3cm, and the distance between the bottom of the first tympanic membrane and the main body of the water pipe connector is 5cm.

[0014] The present invention has the following beneficial effects:

[0015] 1. This high-pressure pipe joint seal utilizes the cooperation of the pipe joint body, connector, round pipe, and contact plate, along with the cooperation of the connecting pipe, retaining ring, water nozzle, and sealing ring, to improve installation efficiency. It avoids the problem of existing pipe joints that rely on threads at both ends to connect to the pipes, requiring significant time for active or passive rotation of the threads. It also avoids the issue of damaged locking structures during disassembly, making reusable pipe joints difficult to recycle, and solves the problem of the locking handle rotating back due to thermal expansion and contraction, leading to reduced connection tightness and leakage.

This high-pressure pipe joint seal, through the combined use of a fixed pipe, warning light, and controller, and the cooperation of a first diaphragm, an electromagnetic plate, and a second diaphragm, enables real-time monitoring of the sealing performance of the device and the water pipe after connection. This avoids the problem of leakage not being detected and repaired in time when leakage occurs due to the inability to monitor the sealing performance, thus improving the sealing effect and practicality of the device.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8A high-pressure pipe joint seal includes a water pipe joint body 1, a connector 2 fixedly mounted on the outer edge of the water pipe joint body 1, a round pipe 3 fixedly mounted on the side of the connector 2 away from the water pipe joint body 1, a contact plate 4 fixedly mounted on the side of the round pipe 3 away from the connector 2, and a connecting pipe 5 fixedly mounted on the side of the round pipe 3 away from the round pipe 3. A retaining ring 6 is fixedly mounted on the outer edge of the connecting pipe 5, a sealing ring 8 is sleeved on the outer edge of the connecting pipe 5, and a water nozzle 7 is fixedly mounted on the end of the connecting pipe 5 away from the contact plate 4. A corrosion-resistant layer 9 is embedded in the inner cavity of the water pipe joint body 1, and a fixing pipe 11 is fixedly mounted on the outer edge of the water pipe joint body 1. A water nozzle 7 is fixedly mounted on the end of the fixing pipe 11 away from the water pipe joint body 1. Equipped with a warning light 12, a first diaphragm 13 is fixedly mounted on the inner wall of the fixing tube 11, an electromagnetic plate 14 is fixedly mounted on the top of the first diaphragm 13, a second diaphragm 15 is fixedly mounted on the inner wall of the fixing tube 11, one end of a fixing rod 16 is fixedly connected to the top of the inner wall of the fixing tube 11, a fixing plate 17 is fixedly mounted on the other end of the fixing rod 16, and a spring 18 is fixedly mounted on the bottom of the fixing plate 17. In the above structure, the corrosion-resistant layer 9 improves the service life of the device and reduces the cost for the user. At the same time, the spring 18 improves the shock absorption effect of the second diaphragm 15, thereby ensuring the stability of the second diaphragm 15 after installation.

[0028] The water pipe connector body 1 has a through hole 10 on its outer edge. The through hole 10 and the connector 2 are positioned correspondingly. The left side of the connector 2 is tightly fitted and fixedly connected to the inner wall diameter of the through hole 10. In the above structure, the tight fit and fixed connection between the left side of the connector 2 and the inner wall diameter of the through hole 10 prevents water from leaking when it flows from the inner wall of the water pipe connector body 1 into the inner wall of the connector 2. This avoids leakage caused by insufficient stability of the connection between the connector 2 and the water pipe connector body 1, and improves the practicality of the device.

[0029] The inner wall of the second diaphragm 15 is provided with a buffer block, and the buffer block is fixedly connected to the end of the spring 18 away from the fixing plate 17. In the above structure, the fixed connection between the buffer block and the end of the spring 18 away from the fixing plate 17 ensures the stability of the second diaphragm 15 after installation, and avoids the impact force between the first diaphragm 13 and the second diaphragm 15 being too large when subjected to pressure, which would cause the second diaphragm 15 to shift in position. At the same time, it avoids the second diaphragm 15 shifting in position from affecting the subsequent detection effect of the internal sealing of the device.

[0030] The first diaphragm 13 is elastic, and the arc surface of the second diaphragm 15 is also fixedly fitted with an electromagnetic plate 14. The electromagnetic plate 14 at the top of the first diaphragm 13 corresponds to the electromagnetic plate 14 on the arc surface of the second diaphragm 15. In the above structure, the elasticity of the first diaphragm 13 allows water to flow through the inside of the water pipe connector body 1 when the seal is intact. The impact force of the water flow can cause the first diaphragm 13 to move the electromagnetic plate 14 upward and fit it against the electromagnetic plate 14 at the bottom of the second diaphragm 15.

[0031] The water pipe connector body 1 is equipped with a controller on its inner wall. The warning light 12, the controller, and the electromagnetic plate 14 are electrically connected. In the above structure, the electrical connection between the warning light 12, the controller, and the electromagnetic plate 14 enables timely warning when the water pipe connector body 1 leaks and the sealing is insufficient. The warning light 12 can then alert the staff, allowing them to promptly plug the leak and improving the practicality of the device.

[0032] The water pipe connector body 1 has a circular hole on its outer edge, and the circular hole and the through hole 10 are arranged opposite each other. The end of the fixed pipe 11 away from the warning light 12 is tightly fitted to the inner wall of the circular hole. In the above structure, the end of the fixed pipe 11 away from the warning light 12 is tightly fitted to the inner wall of the circular hole, so that when the warning light 12 on the inner wall of the fixed pipe 11 checks the sealing performance, leakage will not occur at will, thus avoiding the problem of excessive water consumption caused by accidental leakage.

[0033] There are four retaining rings 6, which are distributed in parallel along the outer edge of the connecting pipe 5. The sealing ring 8 is located between the bottom retaining ring 6 and the water nozzle 7. The sealing ring 8 is made of rubber. In the above structure, the four retaining rings 6 are distributed in parallel along the outer edge of the connecting pipe 5, which increases the stability of the device after it is connected to the water gun. At the same time, the rubber sealing ring 8 can improve the sealing performance of the connection between the connecting pipe 5 and the water nozzle 7 and the water gun, ensuring that there will be no leakage after the connection.

[0034] The water nozzle 7, connecting pipe 5, contact plate 4, round pipe 3, connector 2, water pipe connector body 1, and through hole 10 are interconnected. The bottom outer edge of the water nozzle 7 is arc-shaped. In the above structure, the water nozzle 7, connecting pipe 5, contact plate 4, round pipe 3, connector 2, water pipe connector body 1, and through hole 10 are interconnected, so that the water flowing in the inner wall of the water pipe connector body 1 can be smoothly discharged to the water nozzle 7 and enter the inner cavity of the water spray gun. At the same time, the arc-shaped bottom outer edge of the water nozzle 7 increases the convenience of inserting the water nozzle 7 into the inner wall of the water spray gun, reduces the friction at the connection between the water nozzle 7 and the water spray gun, and improves the practicality of the device.

[0035] In this structure, the outer diameters of the first diaphragm 13 and the second diaphragm 15 are both adapted to the inner diameter of the fixed tube 11. The distance between the first diaphragm 13 and the second diaphragm 15 is 3cm, and the distance between the bottom of the first diaphragm 13 and the main body 1 of the water pipe connector is 5cm. In this structure, the distance between the first diaphragm 13 and the second diaphragm 15 is 3cm, so that when the first diaphragm 13 is subjected to a slight pressure, the first diaphragm 13 will move upward, thereby causing the electromagnetic plate 14 at the top of the first diaphragm 13 to fit with the electromagnetic plate 14 at the bottom of the second diaphragm 15, thus enabling timely detection of the sealing performance of the device after it is connected to the water pipe.

[0036] Working principle: When using this device, first connect the water pipe to be connected to the inner wall of the water pipe connector body 1. Then, take the faucet or spray gun to be installed and insert the connection of the faucet or spray gun into the inner wall of the nozzle 7, sealing ring 8, and connecting pipe 5 until the contact plate 4 is in contact with the connection of the faucet or spray gun. The connection is then complete. The sealing is then detected in real time by the first diaphragm 13, the electromagnetic plate 14, and the second diaphragm 15. When the pressure is normal, the electromagnetic plate 14 at the top of the first diaphragm 13 will be in contact with the electromagnetic plate 14 at the bottom of the second diaphragm 15. At this time, when the two electromagnetic plates 14 are in contact, current will flow and the warning light 12 will not be triggered. When a leak occurs, the impact force sensed by the first diaphragm 13 is insufficient, causing the two electromagnetic plates 14 to not be in contact. At this time, no current flows and a signal is transmitted to the controller. The controller will control the warning light 12 to flash, so that the staff can detect water and electricity leaks in the device in time.
