Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, and particularly relates to a pipeline connection and fixing device for water supply and drainage pipeline construction that is convenient for maintenance. Background Art

[0002] In the existing water supply and drainage pipeline system, pipeline connection devices play a crucial role. They not only connect various pipeline segments to ensure the smooth transmission of fluids, but also need to have good sealing performance to prevent leakage. However, in the actual application process, when it is necessary to repair or maintain the water supply and drainage pipelines, these connection devices often need to be disassembled. A significant problem often faced during the disassembly of traditional pipeline connection devices is that since the pipeline may contain liquid inside, once the connection device is disassembled, the liquid inside the pipeline will quickly drain outwards, causing the surrounding environment to quickly become wet.

[0003] This liquid discharge will not only make the ground slippery, increasing the operation difficulty and safety hazards for maintenance personnel, but may also cause unnecessary damage to surrounding equipment or buildings. In addition, the humid environment may also accelerate the corrosion of metal components and shorten the service life of the pipeline system. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a pipeline connection and fixing device for water supply and drainage pipeline construction that is convenient for maintenance, including a communication valve seat A, a communication valve seat B, valve seat fasteners, a trigger tube, and a notch. The communication valve seat A and the communication valve seat B are connected to each other through the valve seat fasteners. Secondly, the communication valve seat A and the communication valve seat B are interconnected through the trigger tube, and notches are provided at both ends of the trigger tube;

[0005] The communication valve seat A and the communication valve seat B have the same structure;

[0006] The communication valve seat A includes a valve through seat, a valve port, a valve ball, and a spring. The valve seat fasteners are installed on the valve through seat, and the trigger tube is installed on the valve through seat; a valve port is provided on the valve through seat, and the valve ball is elastically installed in the valve through seat through the spring;

[0007] The valve seat fasteners include a sealing seat, a sealing ring, a locking cylinder, a locking nut, and a dust cover. The sealing seat is fixedly installed on the valve through seat of the communication valve seat A, the sealing ring is arranged inside the sealing seat, the sealing ring is threadedly engaged with the locking cylinder, and the locking nut and the locking cylinder are installed on the valve through seat of the communication valve seat B; the locking nut and the valve through seat of the communication valve seat B are installed with the dust cover.

[0008] Preferably, external threads that are threadedly engaged with the locking cylinder and the locking nut are provided on the outside of the valve passage seat of the communicating valve seat B and on the inner wall of the sealing seat; no threads are provided on the outside of the valve passage seat of the communicating valve seat A.

[0009] Preferably, a through hole allowing the trigger tube to penetrate is formed in the valve passage seat. Both ends of the trigger tube are in contact with the valve ball respectively, and the notches formed at both ends of the trigger tube are located inside the valve passage seat.

[0010] Preferably, the dust cover is a corrugated sleeve made of rubber, and the dust cover is located outside the threads provided on the outside of the valve passage seat.

[0011] Preferably, the valve ports of the communicating valve seat A and the communicating valve seat B are respectively connected to two different water supply and drainage pipes.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the unique design of the valve ball and the spring, when the trigger tube is pulled out, the compression spring pushes the valve ball through the elastic force and the liquid pressure, and the valve ball can form a reliable seal, thereby effectively preventing the leakage of the liquid in the pipeline during the maintenance process. The humidity at the maintenance site is greatly reduced, the maintenance environment is improved, and the maintenance efficiency and safety are improved. In addition, during maintenance, only the locking nut and the locking cylinder need to be loosened, and the communicating valve seat A and the communicating valve seat B can be easily separated without completely emptying the entire pipeline system, greatly improving the convenience and flexibility of maintenance. The provided dust cover is a corrugated sleeve made of rubber, which can not only prevent dust and impurities from entering the inside of the connecting device, but also provide a certain protective effect when the connecting device is disassembled, reduce the erosion of external moisture on the internal parts, and extend the service life of the device.

[0021] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0022] A pipe connection and fixing device for water supply and drainage pipeline construction that is convenient for maintenance provided by the present utility model includes a communication valve seat A1, a communication valve seat B2, a valve seat fastener 3, a trigger pipe 4, and a notch 5. The communication valve seat A1 and the communication valve seat B2 are connected to each other through the valve seat fastener 3. Secondly, the communication valve seat A1 and the communication valve seat B2 are interconnected through the trigger pipe 4, and the two ends of the trigger pipe 4 are provided with the notch 5.

[0023] The structures of the communication valve seat A1 and the communication valve seat B2 are the same, enabling the device to be widely applied to various water supply and drainage pipeline systems and meeting the usage requirements in different scenarios.

[0024] The connecting valve seat A1 includes a valve through seat 11, a valve port 12, a valve ball 13, and a spring 14. A valve seat fastener 3 is installed on the valve through seat 11, and a trigger tube 4 is installed on the valve through seat 11. The valve port 12 is provided on the valve through seat 11, and the valve ball 13 is elastically installed in the valve through seat 11 through the spring 14.

[0025] The valve seat fastener 3 includes a sealing seat 31, a sealing ring 32, a locking cylinder 33, a locking nut 34, and a dust cover 35. The sealing seat 31 is fixedly installed on the valve through seat 11 of the connecting valve seat A1. The sealing ring 32 is provided inside the sealing seat 31. The sealing ring 32 is threadedly engaged with the locking cylinder 33. The locking nut 34 and the locking cylinder 33 are installed on the valve through seat 11 of the connecting valve seat B2. The dust cover 35 is installed on the locking nut 34 and the valve through seat 11 of the connecting valve seat B2.

[0026] Example 1:

[0027] Specifically, external threads are machined on the outside of the valve through seat 11 of the connecting valve seat B2. These external threads match the internal threads of the locking cylinder 33 and the locking nut 34. By rotating the locking cylinder 33 and the locking nut 34, a tight connection between the connecting valve seat B2 and another component (such as the connecting valve seat A1 or another pipe interface) can be achieved. At the same time, the inner wall of the sealing seat 31 is also provided with threads adapted to the locking cylinder 33 to further enhance the sealing effect. It should be noted that no threads are provided on the outside of the valve through seat 11 of the connecting valve seat A1, mainly for design considerations to distinguish the roles and functions of the two valve seats during the connection process.

[0028] Specifically, through holes are carefully opened on the valve through seat 11. These through holes allow the trigger tube 4 to pass through smoothly. Both ends of the trigger tube 4 are carefully designed to be in contact with the valve ball 13. When the trigger tube 4 is inserted, it compresses the valve ball 13 and makes it close tightly to the valve port 12, thereby achieving a sealing effect. In addition, notches 5 are opened at both ends of the trigger tube 4. These notches 5 are located inside the valve through seat 11, and their function is to provide a channel for liquid to enter the inside of the trigger tube 4.

[0029] Specifically, the dust cover 35 is cleverly installed outside the threads provided on the outside of the valve through seat 11. It can not only effectively prevent dust and impurities from entering the inside of the connection device, but also provide a certain degree of moisture protection when the connection device is disassembled. The corrugated sleeve made of rubber has good flexibility and sealing performance, and can closely fit the outer contour of the valve through seat 11 to ensure the maximization of the protection effect.

[0030] Specifically, the connecting valve seat A1 and the connecting valve seat B2 are respectively designed with valve ports 12, and these two valve ports are respectively connected to two different water supply and drainage pipes. This design enables the device to be flexibly applied to various water supply and drainage pipe systems, realizing reliable connection between different pipe segments. By adjusting the positions and angles of the connecting valve seat A1 and the connecting valve seat B2, it can easily adapt to different pipe layouts and installation requirements.

[0031] Embodiment 2:

[0032] Ensure that components such as the valve through seats 11, valve ports 12, valve balls 13, and springs 14 of the connecting valve seat A1 and the connecting valve seat B2 are intact and clean. Check whether the seal seats 31, sealing rings 32, locking cylinders 33, locking nuts 34, and dust covers 35 of the valve seat fasteners 3 are complete and confirm that their states are good. Insert one end of the trigger tube 4 into the valve through seat 11 of the connecting valve seat A1. At the same time, the notches 5 at both ends of the trigger tube 4 provide a channel for liquid to enter the inside of the trigger tube. However, due to the sealing effect of the valve ball 13, liquid will only pass through when the trigger tube 4 is fully inserted and compresses the valve ball 13. Move the connecting valve seat B2 close to the connecting valve seat A1, ensure that their valve through seats 11 are aligned, and insert the other end of the trigger tube 4 into the valve through seat 11 of the connecting valve seat B2. Install the seal seat 31 outside the valve through seat 11 of the connecting valve seat B2 and place the sealing ring 32 inside the seal seat 31. Screw the locking cylinder 33 into the seal seat 31 and make it in close contact with the sealing ring 32. At the same time, screw the locking nut 34 until it is in close contact with the locking cylinder 33. At this time, the connecting valve seat A1 and the connecting valve seat B2 are firmly connected together through the trigger tube 4 and the valve seat fasteners 3 and form a good sealing effect. The two valve ports 12 are respectively connected to two different water supply and drainage pipes to realize the normal operation of the pipe system.

[0033] When maintenance is required, just loosen the locking nut 34 and the locking cylinder 33, release the connection between the connecting valve seat A1 and the connecting valve seat B2, and pull out the trigger tube 4. At this time, due to the absence of the trigger tube 4, the valve ball 13 will be in a compressed state and closely fit the through hole allowing the trigger tube 4 to pass through, preventing a large amount of liquid in the pipe from leaking out.

[0034] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall all fall within the protection scope of the present utility model.
