Description

Technical Field

[0001] The utility model relates to a water storage tank, in particular to a high temperature resistant water tank water inlet structure. Background Art

[0002] As industrial technology continues to advance, one of the industries with a growing demand for high-performance equipment that can work stably under extreme temperature conditions is the hot water storage and supply field.

[0003] In many industrial processes, such as chemical, oil refining, power plants and other high-temperature operating environments, traditional water tanks are often unable to withstand long-term high temperatures due to material limitations, resulting in equipment damage, reduced efficiency and even safety hazards.

[0004] A water inlet and a water outlet are usually required on the high temperature resistant water tank. A water inlet pipe needs to be set at the position of the water inlet. The high temperature liquid is transmitted to the high temperature resistant water tank for storage through the water inlet pipe. In order to facilitate the control of the entry of hot water, a valve needs to be set on the water inlet pipe.

[0005] Most of the existing high-temperature resistant water tank water inlet structures adopt the box water inlet structure as recorded in CN201820591253.4. The box water inlet is connected to the water inlet valve through a pipe, the water inlet valve is connected to the filter through a pipe, and the backflow preventer is connected to the water tank through a pipe.

[0006] It is difficult to adjust the opening area of ​​the water inlet according to the water pressure in the pipeline through the above-mentioned box water inlet structure, and the water flows out along the axial direction after entering the box, and the dispersion is poor. Utility Model Content

[0007] The utility model aims to provide a high temperature resistant water tank water inlet structure, which serves as the water inlet of the high temperature resistant water tank and can automatically adjust the water inlet opening area according to the water pressure. After the water flows into the water tank, it disperses toward the surroundings and has good dispersion.

[0008] In order to achieve the above-mentioned purpose, the utility model provides a high-temperature resistant water tank water inlet structure, which includes a water inlet pipe fixedly connected to the side wall of the water tank and connected to the inner cavity of the water tank, a limiting end plate is provided at the inner end of the water inlet pipe, a movable tube extending into the water inlet pipe is fixedly connected to the limiting end plate, the outer end of the movable tube is arranged to be open, a plurality of long water outlet grooves parallel to the axial direction are arranged on the side wall of the movable tube along the circumferential direction, a plurality of guide rods arranged sealingly passing through the side wall of the water tank are provided at the outer end of the limiting end plate, a spring and a limiting locking unit for locking the spring are sequentially sleeved on the outer end of the guide rod, and when the limiting locking unit is in a locked state, the limiting end plate sealingly covers the inner wall of the water tank.

[0009] Preferably, the limiting locking unit comprises a flat washer pressed on the outer end of the spring and a nut arranged outside the flat washer, and the outer end of the guide rod is provided with an external thread corresponding to the nut.

[0010] Preferably, a limiting groove for accommodating the inner end of the spring is provided on the outer side of the water tank side wall.

[0011] Preferably, a guide hole for the guide rod to pass through is provided on the side wall of the water tank; and an annular sealing ring is embedded in the guide hole.

[0012] Preferably, a flange is provided at the outer end of the water inlet pipe, and a sealing ring groove is provided on the end surface of the flange.

[0013] Preferably, a first annular groove is arranged on the outer side of the limiting end plate, and a first annular sealing gasket is arranged in the first annular groove.

[0014] Preferably, a second annular groove communicating with the first annular groove is arranged on the outer side of the inner end of the movable tube; a second annular sealing gasket is arranged in the second annular groove, and the second annular sealing gasket is perpendicular to the first annular sealing gasket.

[0015] Preferably, the outer surface of the first annular sealing gasket is arranged to protrude from the surface of the limiting end plate.

[0016] According to the above technical scheme, the utility model provides a high-temperature resistant water tank water inlet structure, which includes a water inlet pipe fixedly connected to the side wall of the water tank and connected to the inner cavity of the water tank, a limiting end plate is provided at the inner end of the water inlet pipe, a movable tube extending into the water inlet pipe is fixedly connected to the limiting end plate, the outer end of the movable tube is arranged to be open, and a plurality of long water outlet grooves parallel to the axial direction are arranged on the side wall of the movable tube along the circumferential direction, a plurality of guide rods sealingly arranged through the side wall of the water tank are provided at the outer end of the limiting end plate, and a spring and a limiting locking unit for locking the spring are sequentially sleeved on the outer end of the guide rod, and when the limiting locking unit is in a locked state, the limiting end plate sealingly covers the inner wall of the water tank.

[0017] The high-temperature resistant water tank water inlet structure has the following beneficial effects: when the limit locking unit is in a locked state, the limit end plate seals the cover on the inner wall of the water tank. At this time, the multiple long water outlet grooves serving as the water inlet are enclosed in the water inlet pipe. At this time, the water inlet will not flow into the water tank. When the valve in the pipeline connected to the water inlet pipe is opened, the water flow impacts the limit end plate under the action of the water pressure, causing the spring to be compressed. One end of the long water outlet groove close to the limit end plate will also partially protrude from the outside of the water inlet pipe to form a water inlet. As the water pressure increases, the exposed area of ​​the long water outlet groove increases, so that the water inlet opening area can be automatically adjusted according to the water pressure. When the valve is closed, under the resetting action of the spring, the movable pipe returns to its position, and the long water outlet groove is retracted into the water inlet pipe again to stop water from flowing in. In addition, the water flow of the high-temperature resistant water tank water inlet structure disperses toward the surroundings after entering the water tank, and has good dispersion.
