[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.
[0021] Please see Figure 1-4This utility model provides a technical solution: a water supply pipeline pressure relief device, including a valve 1 for connecting the water supply pipeline, a handle 2 movably mounted on the top of the valve 1 for the user to open the sealing gasket 10, a pressure relief mechanism 3 fixedly mounted on one side of the top of the valve 1 for mounting corresponding components, a cavity inside the valve 1, a partition plate 4 fixedly mounted inside the valve 1 for sealing, a cavity inside the pressure relief mechanism 3, a conduit 5 connected to the bottom of the pressure relief mechanism 3 for mounting corresponding components, a cavity inside the conduit 5, a connecting rod 6 mounted near the top of the pressure relief mechanism 3 for movement, a hollow tube 7 fixedly mounted at the bottom of the connecting rod 6 for gas flow, a counterweight sealing ball 8 mounted near the bottom of the conduit 5 for counterweight sealing, and pressure relief grooves 9 on both sides of the hollow tube 7 near the top and bottom for facilitating the outward discharge of air pressure.
[0022] Furthermore, the bottom end of the lever 2 passes through the valve 1 and extends into its interior, wherein the lever 2 facilitates the user to open the sealing gasket 10.
[0023] Furthermore, a sealing gasket 10 is fixedly installed at the bottom end of the handle 2. The bottom end of the sealing gasket 10 penetrates the partition plate 4 and extends to its outside. The sealing gasket 10 serves to seal.
[0024] Furthermore, one side of the pressure relief mechanism 3 is connected to an exhaust pipe 11, which serves to relieve pressure during exhaust.
[0025] Furthermore, support springs 12 are fixedly installed on both sides of the top of the connecting rod 6. The top of the support springs 12 is fixedly connected to the top of the pressure relief mechanism 3. The support springs 12 can support the connecting rod 6.
[0026] Furthermore, the outer wall of the counterweight sealing ball 8 contacts the inner wall of the conduit 5, the counterweight sealing ball 8 and the conduit 5 are movably connected, and the conduit 5 and the valve 1 are threadedly connected. The counterweight sealing ball 8 plays the role of counterweight sealing.
[0027] Furthermore, the bottom end of the hollow tube 7 passes through the pressure relief mechanism 3, the valve 1, and the conduit 5 in sequence and is fixedly connected to the counterweight sealing ball 8. The hollow tube 7 is movably connected to the pressure relief mechanism 3, the valve 1, and the conduit 5, and the hollow tube 7 facilitates the outward flow of gas.
[0028] Furthermore, the pressure relief groove 9 and the hollow tube 7 are integrated into one design, with the pressure relief groove 9 facilitating the release of air pressure.
[0029] Working principle: When using this device, the user connects the conduit 5 at the bottom of the pressure relief mechanism 3 to the valve 1 via a thread. When the pressure inside the valve 1 increases, the pressure gradually pushes up the counterweight sealing ball 8 inside the conduit 5. When the counterweight sealing ball 8 is pushed to the top of the conduit 5, it separates from the inner wall of the conduit 5, allowing the air pressure to flow through the pressure relief groove 9 on the hollow tube 7 and be transported to the inside of the pressure relief mechanism 3. Then, the air pressure is discharged outward through the exhaust pipe 11 on the pressure relief mechanism 3 to relieve pressure. After the pressure is released, the pressure becomes lower, and the counterweight sealing ball 8, lacking pressure, slides down under the action of power to re-seal.
[0030] Based on the above work process, we can conclude that:
[0031] This water supply pipeline pressure relief device simplifies the overall structure by incorporating a pressure relief groove 9, a hollow pipe 7, a counterweight sealing ball 8, and a pressure relief mechanism 3. This allows for timely pressure relief, preventing pipeline damage caused by excessive pressure. It also facilitates installation and use, enhancing user convenience and practicality, and meeting user needs.
