Abstract
Description
Technical Field
[0001] This utility model is a water distribution device, belonging to the field of air conditioning engineering. Background Technology
[0002] The manifold is a key component in an air conditioning system, serving to distribute and collect water flow. In centralized heating or cooling projects, manifolds are typically installed on the supply and return water mains to effectively distribute and regulate the flow rate to each air-conditioned zone. The design of a manifold usually includes a series of pipe fittings for connecting the supply and return water pipes of each loop. In existing technology, when the pipe fittings are disassembled from the connecting pipes for cleaning and maintenance of the main pipe, residual water inside the main pipe will flow down the connecting pipes and drip onto the ground. Since the liquid inside the main pipe may be hot water that has just undergone heat circulation, hot water dripping from the connection points onto the skin of operators can easily cause injury. Therefore, a manifold device is needed that can prevent the liquid inside the main pipe from flowing out when the connecting pipes are separated from the pipe fittings. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water distribution device to solve the problems mentioned in the background technology. This utility model avoids the leakage of residual water inside the main pipe at the moment of separation of the connecting pipe and the pipe joint.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a water distribution device includes a main pipe with an inlet at one end and a drain valve at the end of the main pipe away from the inlet. Multiple flow regulating valves are installed above the main pipe, and multiple connecting pipes are installed at the bottom of the main pipe. The position and number of the connecting pipes correspond to the flow regulating valves. Each connecting pipe has a pipe fitting at its bottom. The connecting pipe communicates with the interior of the main pipe. A sealing element is installed at the end of the connecting pipe near the pipe fitting, and a pushing element is installed at the end of the pipe fitting near the connecting pipe.
[0005] Furthermore, the sealing element includes a threaded tube, which is fixedly installed on the side of the connecting tube near the pipe joint. The other end of the threaded tube is inserted into the connecting tube. Two limiting plates are symmetrically installed on one end of the threaded tube inside the connecting tube. The limiting plates are fixedly installed on the connecting tube. The threaded tube and the limiting plates are symmetrically provided with movable grooves. A sealing plate is installed on one end of the threaded tube.
[0006] Furthermore, a collar is installed on one side of the sealing plate, and a sliding block is installed on the side of the sealing plate away from the collar. The collar and the sliding block are respectively inserted into two movable slots. The collar is sleeved on the guide rod, and the guide rod is installed inside the movable slot. A telescopic spring is installed at the bottom of the sliding block, and the other end of the telescopic spring is installed in the movable slot opened on the limiting plate.
[0007] Furthermore, the pusher includes an inner ring, which is fixedly installed inside the pipe joint. The diameter of the inner ring is smaller than the inner diameter of the pipe joint. An installation groove is provided between the pipe joint and the inner ring. The inner wall of the installation groove has a threaded structure. Two push plates are symmetrically installed at the bottom of the inner ring.
[0008] Furthermore, ball bearings are installed at the bottom of both push plates, and the cross-section of the push plates is arc-shaped.
[0009] Furthermore, a connecting sleeve is fixedly installed at the end of the pipe fitting away from the inner ring, and a positioning groove is provided on the connecting sleeve, with a sealing ring fitted inside the positioning groove.
[0010] The beneficial effects of this utility model are as follows: The water distribution device of this utility model uses the thrust generated by the rebound of the telescopic spring to drive the sealing plate to move to one side of the threaded pipe. When the pushing plate is completely moved out of the threaded pipe, it seals the outlet of the threaded pipe, preventing the liquid inside the main pipe from leaking out and reducing the probability of injury to the operator.
[0011] The guide rod and collar work together to restrict the movement trajectory of the sealing plate inside the threaded tube, allowing the sealing plate to move smoothly up and down parallel inside the threaded tube. This prevents the sealing plate from flipping during movement and improves its sealing effect.
[0012] By rotating the pipe fitting, the threaded pipe is installed into the installation groove, and the push plate is pushed into the threaded pipe, causing the sealing plate to move downwards. The sealing plate moves to the bottom of the limiting plate, allowing water to flow into the pipe fitting through the gap between the sealing plate and the limiting plate and be delivered into the delivery pipe. As the pipe fitting is rotated, the ball bearings roll on the sealing plate, reducing the friction between the push plate and the sealing plate and improving the installation efficiency of the pipe fitting.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1-5 This utility model provides a technical solution: a water distribution device, including a main pipe 1, an inlet 3 installed at one end of the main pipe 1, a drain valve 6 installed at the end of the main pipe 1 away from the inlet 3, multiple flow regulating valves 2 installed above the main pipe 1, and multiple connecting pipes 4 installed at the bottom of the main pipe 1. The position and number of the connecting pipes 4 correspond to the flow regulating valves 2. Each connecting pipe 4 has a pipe joint 5 installed at its bottom. The connecting pipe 4 communicates with the inside of the main pipe 1. A sealing element is installed at the end of the connecting pipe 4 near the pipe joint 5, and a pushing element is installed at the end of the pipe joint 5 near the connecting pipe 4. The flow regulating valves 2 can control the speed of water flowing into the connecting pipe 4, thereby controlling the pressure of the water flow inside the connecting pipe 4.
[0022] Please see Figure 2 and Figure 3The sealing element includes a threaded tube 7, which is fixedly installed on the side of the connecting pipe 4 near the pipe joint 5. The other end of the threaded tube 7 is inserted into the connecting pipe 4. Two limiting plates 8 are symmetrically installed on the end of the threaded tube 7 inside the connecting pipe 4. The limiting plates 8 are fixedly installed on the connecting pipe 4. The threaded tube 7 and the limiting plates 8 are symmetrically provided with movable grooves 9. A sealing plate 10 is installed on one end of the threaded tube 7. A collar 11 is installed on one side of the sealing plate 10. A sliding block 13 is installed on the side of the sealing plate 10 away from the collar 11. The collar 11 and the sliding block 13 are respectively inserted into the two movable grooves 9. The collar 11 is sleeved on the guide rod 12. The guide rod 12 is installed inside the movable groove 9. A telescopic spring 14 is installed at the bottom of the sliding block 13. The other end of the telescopic spring 14 is installed in the movable groove 9 opened on the limiting plate 8. The guide rod 12 can limit the angle of the sealing plate 10 moving up and down inside the movable groove 9, and prevent the sealing plate 10 from flipping during the up and down movement.
[0023] Please see Figure 4 and Figure 5 The pusher includes an inner ring 15, which is fixedly installed inside the pipe connector 5. The diameter of the inner ring 15 is smaller than the inner diameter of the pipe connector 5. An installation groove 17 is provided between the pipe connector 5 and the inner ring 15. The inner wall of the installation groove 17 has a threaded structure. Two push plates 16 are symmetrically installed at the bottom of the inner ring 15. Ball bearings 18 are installed at the bottom of both push plates 16. The cross-section of the push plates 16 is arc-shaped. A connecting sleeve 19 is fixedly installed at the end of the pipe connector 5 away from the inner ring 15. A positioning groove 20 is provided on the connecting sleeve 19. A sealing ring 21 is sleeved inside the positioning groove 20. The cooperation between the positioning groove 20 and the sealing ring 21 allows the conveying pipe to be installed on the connecting sleeve 19. The limiting ring clamps one end of the conveying pipe inside the positioning groove 20. The inner wall of the sealing plate 10 of the conveying pipe is in contact with the sealing ring 21, increasing the friction between the conveying pipe and the connecting sleeve 19.
[0024] Detailed Implementation: The thrust generated by the rebound of the telescopic spring 14 drives the sealing plate 10 to move towards the threaded pipe 7. When the pushing plate 16 is completely removed from the threaded pipe 7, it seals the outlet of the threaded pipe 7, preventing liquid leakage from the main pipe 1 and reducing the probability of injury to the operator. The cooperation of the guide rod 12 and the collar 11 restricts the movement trajectory of the sealing plate 10 inside the threaded pipe 7, allowing the sealing plate 10 to move smoothly up and down parallel inside the threaded pipe 7, preventing the sealing plate 10 from flipping during movement. This improves the sealing effect of the sealing plate 10. By rotating the pipe joint 5, the threaded pipe 7 is installed into the installation groove 17, and the pusher plate 16 is pushed into the threaded pipe 7, causing the sealing plate 10 to move downwards and move to the bottom of the limiting plate 8. This allows water to flow through the gap between the sealing plate 10 and the limiting plate 8 into the pipe joint 5 and be transported into the delivery pipe. As the pipe joint 5 is rotated, the ball bearing 18 rolls on the sealing plate 10, reducing the friction between the pusher plate 16 and the sealing plate 10 and improving the installation efficiency of the pipe joint 5.
