Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water tank drainage technology, and in particular relates to a ceiling-mounted high-level water tank pressure relief device. Background Technology
[0002] To save bathroom space and improve comfort, water heaters are often installed inside the ceiling. However, when the water heater is heating, the internal pressure increases significantly, potentially leading to safety hazards. Currently, people typically release pressure by actively opening the faucet connected to the water heater. Since people are unaware of the actual pressure inside the heater, constantly draining the water can waste hot water. Furthermore, it's impractical to remain near the water heater at all times to release pressure, resulting in delays and the inability to prevent accidents. Utility Model Content
[0003] To address the above problems, this utility model provides a ceiling-mounted high-level water tank pressure relief device.
[0004] This utility model is implemented as follows: A ceiling-mounted high-level water tank pressure relief device includes a water tank. A drain pipe is installed downward on one side of the water tank. A T-junction is installed at the lower end of the drain pipe. A water outlet pipe is connected to one side of the T-junction. A shut-off valve is installed on the water outlet pipe. Opening the shut-off valve can actively release pressure, and hot water in the water tank can flow out along the drain pipe and the water outlet pipe. A pressure relief valve is connected to the lower end of the T-junction for pressure relief. A valve body is installed outside the pressure relief valve. The valve body has a cylindrical structure that is narrow at the top and wide at the bottom, and both ends of the valve body are connected to the outside. Hot water in the drain pipe flows out along the valve body. A base plate is horizontally fixed in the lower part of the valve body to support the column and the spring ring. A column is vertically fixed in the middle of the upper part of the base plate. A spring ring is sleeved on the column to limit the position of the spring ring and prevent the spring ring from shifting. A top block is installed above the spring ring. The two ends of the spring ring tightly abut against the base plate and the top block to ensure that the spring ring is in a compressed state. A stop block is fixedly installed at the upper end of the valve body. The stop block is shaped like a frustum. The inner wall of the valve body, which is narrower at the top and wider at the bottom, matches the shape of the side wall of the stop block. The side wall of the stop block and the inner wall of the valve body are tightly pressed together to ensure a tight connection between the stop block and the valve body and prevent water leakage. The diameter of the top block is smaller than the diameter of the lower part of the valve body to ensure the free movement of the top block in the valve body. Multiple drain holes are evenly opened on the bottom plate. When the pressure in the water tank is too high, the water in the drain pipe pushes the stop block downwards. The water flows along the gap between the stop block and the valve body to the lower part of the valve body and then is discharged from the drain hole to relieve pressure. A pressure sensor is installed in the water tank, and a display screen is installed on the wall near the outlet pipe. The pressure sensor is electrically connected to the display screen. The pressure sensor monitors the pressure in the water tank and transmits the data to the display screen in a timely manner. People can open the shut-off valve in time according to the pressure data on the display screen to actively relieve pressure, ensuring safety and avoiding the waste of hot water.
[0005] Preferably, an annular groove is formed on the outer wall of the stop block, and an O-ring is provided in the annular groove to ensure the stability of the position of the O-ring. When the stop block abuts against the inner wall of the valve body, the O-ring is tightly abutted against the inner wall of the valve body, further improving the tightness of the connection between the stop block and the inner wall of the valve body and preventing water leakage.
[0006] Preferably, a sleeve is vertically fixed at the lower end of the top block, and the diameter of the spring ring is smaller than the inner diameter of the sleeve to limit the position of the spring ring and prevent the spring ring from shifting position.
[0007] Preferably, the column is a cylindrical structure.
[0008] The beneficial effects of this utility model are: the pressure sensor monitors the pressure in the water tank and transmits the data to the display screen in a timely manner. People can open the shut-off valve in time according to the pressure data on the display screen to actively perform pressure relief, ensuring safety while avoiding the waste of hot water; when the pressure in the water tank is too high, the water in the drain pipe pushes down the baffle, and the water flows along the gap between the baffle and the valve body to the lower part of the valve body, and then is discharged from the drain hole. The pressure can be automatically relieved without people staying near the water heater, avoiding the occurrence of safety accidents. Attached Figure Description

[0013] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.
[0014] like Figure 1-3The ceiling-mounted high-level water tank pressure relief device shown includes a water tank 1. A drain pipe 2 is installed downward on one side of the water tank 1. A tee 3 is installed at the lower end of the drain pipe 2. A water outlet pipe 4 is connected to one side of the tee 3. A shut-off valve 5 is installed on the water outlet pipe 4. Opening the shut-off valve 5 can actively release pressure, and hot water in the water tank 1 can also flow out along the drain pipe 2 and the water outlet pipe 4. A pressure relief valve 6 is connected to the lower end of the tee 3 for pressure relief. A valve body 7 is installed on the outside of the pressure relief valve 6. The valve body 7 has a cylindrical structure that is narrow at the top and wide at the bottom, and both ends of the valve body 7 are connected to the outside. Hot water in the drain pipe 2 flows out along the valve body 7. A base plate 8 is horizontally fixed in the lower part of the valve body 7 to support the column 9 and the spring ring 10. A column 9 with a cylindrical structure is vertically fixed in the middle of the upper end of the base plate 8. A spring ring 10 is fitted onto the column 9 to limit its position and prevent displacement. A top block 11 is positioned above the spring ring 10. Both ends of the spring ring 10 are tightly abutted against the bottom plate 8 and the top block 11 to ensure the spring ring 10 is in a compressed state. A stop block 12 is fixedly mounted on the upper end of the top block 11. The stop block 12 is frustoconical in shape, and its shape matches the side wall of the stop block 12 at the inner wall of the valve body 7, which is narrower at the top and wider at the bottom. The side wall of the stop block 12 is tightly abutted against the inner wall of the valve body 7 to ensure a tight connection between the stop block 12 and the valve body 7 and prevent water leakage. The diameter of the top block 11 is smaller than the diameter of the lower part of the valve body 7 to allow the top block 11 to move freely up and down within the valve body 7. The water tank 1 has multiple drainage holes 13 evenly distributed on the base plate 8. When the pressure in the water tank 1 is too high, the water in the drain pipe 2 pushes down the baffle 12, and the water flows along the gap between the baffle 12 and the valve body 7 to the lower part of the valve body 7, and then is discharged from the drainage holes 13 to relieve pressure. The water tank 1 is equipped with a pressure sensor 14, and a display screen 15 is installed on the wall near the outlet pipe 4. The pressure sensor 14 is electrically connected to the display screen 15. The pressure sensor 14 monitors the pressure in the water tank 1 and transmits the data to the display screen 15 in a timely manner. People can open the shut-off valve 5 in time according to the pressure data on the display screen 15 to actively relieve pressure, ensuring safety and avoiding the waste of hot water.
[0015] An annular groove 16 is provided on the outer wall of the stop block 12, and an O-ring seal 17 is provided in the annular groove 16 to ensure the stability of the position of the O-ring seal 17. When the stop block 12 abuts against the inner wall of the valve body 7, the O-ring seal 17 abuts tightly against the inner wall of the valve body 7, further improving the tightness of the connection between the stop block 12 and the inner wall of the valve body 7 and preventing water leakage.
[0016] A sleeve 18 is vertically fixed at the lower end of the top block 11. The diameter of the spring ring 10 is smaller than the inner diameter of the sleeve 18, which limits the position of the spring ring 10 and prevents the spring ring 10 from shifting.
[0017] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
