Description

Technical Field

[0001] This utility model relates to a pressure stabilizing tank. Specifically, it relates to a water inlet mechanism and its pressure stabilizing tank. Background Technology

[0002] A pressure stabilizing tank is a device used in liquid or gas systems. It is mainly used to maintain the pressure stability within the system, reduce pressure fluctuations, protect pumps and piping systems, and improve the overall efficiency of the system. By holding a certain amount of liquid or gas, the pressure stabilizing tank can provide additional flow when demand changes, helping to maintain the pressure stability within the system. The inlet of the pressure stabilizing tank is mostly located at the bottom of the tank body, and usually needs to be extended by an inlet mechanism to allow subsequent liquid to enter the pressure stabilizing tank through the inlet.

[0003] Most existing water inlet mechanisms are extension bends, which are usually bolted to the flange at the tank inlet. The inlet is extended by the extension bend to facilitate the flow of liquid in the tank. However, since the inlet is located at the bottom of the tank, it is inconvenient to tighten the bolts when using them for fixing. Furthermore, bolt fixing makes the installation and disassembly of the tank and water inlet mechanism inconvenient and hinders subsequent maintenance. Therefore, this solution proposes a water inlet mechanism and its pressure stabilizing tank to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a water inlet mechanism and its pressure stabilizing tank to solve the problems mentioned in the background art.

[0042] It should be noted that the connecting pipe 4 is inserted into the top of the extension pipe bracket 3. Both the outer wall of the connecting pipe 4 and the top of the extension pipe bracket 3 are provided with sealing layers. The sealing layer of the connecting pipe 4 is used to seal the connection between the connecting pipe 4 and the inlet pipe 2, and the sealing layer of the extension pipe bracket 3 is used to seal the connection between the extension pipe bracket 3 and the connecting flange 5. One end of the pull rod 6 is slidably inserted into the sliding groove, and the end of the pull rod 6 away from the sliding groove is fixedly connected to the fixing frame 7. The return spring 12 is disposed in the sliding groove, one end of the return spring 12 is fixedly connected to the inner wall of the sliding groove, and the other end of the return spring 12 is fixedly connected to the pull rod 6 away from the fixing frame 7. One end of the fixed frame 7 is fixedly connected. Pulling the pull rod 6 moves the fixed frame 7, causing the fixed frames 7 to move away from each other. The extension pipe rack 3 is placed at the bottom of the connecting flange 5, and the connecting pipe 4 is inserted and connected to the water inlet pipe 2. The pull rod 6 is released, and the pull rod 6 is moved by the elastic force of the return spring 12.

The other end of the fixing spring 10 is fixedly connected to the end of the push frame 8 near the locking rod 11. Moving the push rod 9 causes the push plate to move, which in turn causes the locking rod 11 to move upward. When the fixed frames 7 are close to each other and fit against the top of the connecting flange 5, the push rod 9 is released. The fixed spring 10 pulls the push plate to move, which in turn pushes the locking rod 11 to move, allowing the locking rod 11 to pass through the fixed frame 7 and insert into the connecting flange 5.

The pull rod 6 is released, and the push rod 9 is pushed. The push rod 9 moves the extension pipe bracket 3 away from the pressure stabilizing tank body 11. The push plate moves, which in turn moves the locking rod 11, causing it to move upwards. The return spring 12 pulls the pull rod 6, which in turn moves the fixing bracket 7, bringing the fixing brackets 7 closer together and connecting them to the top of the connecting flange 5. The fixing bracket 7 secures the extension pipe bracket 3 to the connecting flange 5. The push rod 9 is released, and the fixing spring 10 pulls the push plate, which in turn moves the locking rod 11, causing it to pass through the fixing bracket 7 and connect to the connecting flange 5.
