Description

Technical Field

[0001] This utility model belongs to the technical field of brewing equipment, and in particular relates to a water inlet pipe device for a high-temperature water pump. Background Technology

[0002] In the traditional Chinese liquor industry, a large amount of hot water is needed to moisten and heat the grain materials during the brewing process. The traditional water supply method is to manually fill the hot water into the barrel and transfer it, which poses risks such as scalding. The existing high-temperature hot water pump will produce severe cavitation when drawing hot water above 95°C, which will seriously affect the pump body and water supply efficiency. In addition, it requires frequent water filling after each start-up, making the operation cumbersome.

[0003] Most existing solutions to the above-mentioned technical problems involve improving the internal structure of the high-temperature hot water pump. However, the improved structure of the high-temperature hot water pump is complex, costly, and has limited applicability. It cannot solve the problem that the high-temperature hot water pump will cause severe cavitation when drawing hot water above 95°C during the brewing process, which seriously affects the pump body and water supply efficiency, and requires frequent water filling after each start-up.

[0004] For example, patent document CN222759952U discloses a high-temperature hot water pump with a double-balance pipe balancing device and a buffer tank. The pump includes a base, a pump body fixedly connected to the base, a pump inlet, a balance pipe connected to the pump body's balance chamber side, a buffer tank connected to the balance pipe, and a balance pipe connected to the pump inlet side between the buffer tank and the pump inlet. Both the balance pipe and the pump inlet side have two pipes; the balance pipe to the pump body's balance chamber side is connected to the top of the buffer tank, and the balance pipe to the pump inlet side is connected to the bottom of the buffer tank. This invention addresses the technical problems of existing high-temperature hot water pumps, such as cavitation at the pump inlet, which causes a sharp drop in pump flow and head, resulting in low efficiency, increased power consumption, unstable operation, and increased vibration. However, it does not solve the problem of high-temperature hot water pumps drawing hot water above 95℃ during brewing processes and requiring frequent priming after each start-up.

[0005] Therefore, there is an urgent need to design a device suitable for the brewing process, that reduces water pump cavitation, and that does not require repeated water filling, in order to solve the problems existing in the current technology. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides an inlet pipe device for a high-temperature water pump, including a water pump, an automatic air vent valve A, a hose A, a Y-type filter valve, an automatic air vent valve B, a hose B, and a bottom valve. The automatic air vent valve A is installed on the water pump. The first inlet of the Y-type filter valve is connected to the automatic air vent valve A through the hose A. The automatic air vent valve B is installed on the second inlet of the Y-type filter valve. The bottom valve is connected to the automatic air vent valve B through the hose B. A detachable screw cap is installed at the third inlet of the Y-type filter valve.

[0007] Furthermore, it also includes a fixing plate, on which the first inlet and the second inlet of the Y-type filter valve are fixed, and the third inlet of the Y-type filter valve is set facing upward away from the fixing plate.

[0008] Furthermore, the fixed plate includes an upper plate, a lower plate, a connecting plate, and an adjustment mechanism. The lower plate is mounted on the connecting plate, the upper plate is mounted above the lower plate, and the adjustment mechanism is connected to the side plate of the connecting plate.

[0009] Furthermore, the adjustment mechanism includes an adjustment handle and an adjustment screw. One end of the adjustment screw is provided with an external thread and is threadedly connected to the side plate of the connecting plate; the other end is provided with a through hole in the vertical direction and is plugged into the adjustment screw.

[0010] Furthermore, the adjusting handle is a stepped column, and the diameter of the end inserted into the adjusting screw matches the diameter of the through hole provided on the adjusting screw.

[0011] Furthermore, the connecting plate is configured as an arch shape, with a horizontal arc-shaped groove at the top, and the lower clamping plate is disposed on the arc-shaped groove.

[0012] Furthermore, the lower plate has an arc surface in the middle along its length, and its curvature matches the arc-shaped groove on the connecting plate; the two sides of the lower plate along its length are flat, and mounting holes A are provided at the four corners of the flat surfaces.

[0013] Furthermore, the upper plate has mounting platforms at both ends and an arc strip in the middle. The mounting platform is provided with mounting holes B that match mounting holes A. The upper plate is fixed to the lower plate through the vertical mounting holes A of the lower plate. The arc strip matches the curvature of the arc surface.

[0014] In summary, the beneficial effects of this utility model are as follows: By using a Y-type filter valve, a foot valve, and automatic air vent valves A and B, it achieves the requirement of multiple start-stop operations with a single water filling. Before use, water is first filled through the third inlet of the Y-type filter valve, and the water pump is started to expel the gas in the pipeline through automatic air vent valves A and B. Afterward, the water pump is turned off and then restarted. The foot valve draws water into the pipeline, and the one-way valve function of the foot valve prevents water loss. Therefore, repeated air venting and water filling are unnecessary, allowing for multiple start-stop operations with a single water filling, reducing water pump cavitation, simplifying operation, and lowering the cost of custom-designed anti-cavitation water pumps.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4 As shown in the figure, this utility model provides an inlet pipe device for a high-temperature water pump to reduce water pump cavitation, while solving the technical problems of repeated water filling and cumbersome operation of traditional water pumps, further improving hot water supply efficiency and reducing the customized cost of water pump anti-cavitation.

[0027] This embodiment provides a high-temperature water pump inlet pipe device including a water pump, an automatic air vent valve A, a hose A, a Y-type filter valve, an automatic air vent valve B, a hose B, and a foot valve. The automatic air vent valve A is installed on the water pump. The first inlet of the Y-type filter valve is connected to the automatic air vent valve A via hose A. The automatic air vent valve B is installed on the second inlet of the Y-type filter valve. The foot valve is connected to the automatic air vent valve B via hose B. A removable screw cap is installed at the third inlet of the Y-type filter valve. The water pump 1 is placed at the usage site. The hoses A3 and B7 are stainless steel hoses. Water is introduced into the pipeline through the third inlet 503 of the Y-type filter valve. The automatic air vent valves A2 and B8 release gas from the water in the pipeline through their float venting function. The Y-type filter valve 5, in conjunction with the unidirectional flow function of the foot valve 6, ensures that the water in the pipeline does not leak out.

[0028] The automatic vent valves A2 and B8 are vertically installed float-type vent valves.

[0029] The Y-type filter valve 5 is a Y-type filter valve with a removable screw cap and a cylindrical filter screen.

[0030] The bottom valve 6 is a one-way valve with a spring and a removable filter.

[0031] In this embodiment, the inlet pipe device for the high-temperature water pump further includes a fixing plate 4. The first inlet 501 and the second inlet 502 of the Y-type filter valve are fixed on the fixing plate 4, and the third inlet 503 of the Y-type filter valve is positioned facing upwards away from the fixing plate 4. The fixing plate 4 fixes the pipeline and simultaneously clamps the Y-type filter valve 5, thereby enabling the suction of high-temperature water.

[0032] In this embodiment, the fixing plate 4 includes an upper fixing plate 401, a lower fixing plate 402, a connecting plate 403, and an adjustment mechanism. The lower fixing plate 402 is mounted on the connecting plate 403, and the upper fixing plate 401 is mounted above the lower fixing plate 402. The adjustment mechanism is connected to the side plate of the connecting plate 403. By rotating the adjusting handle 404, the distance between the adjusting screw 405 and the connecting plate 403 is adjusted, thereby fixing the fixing plate 4. The upper fixing plate 401 and the lower fixing plate 402 are used to clamp the first inlet 501 and the second inlet 502 of the Y-type filter valve.

[0033] In this embodiment, the adjustment mechanism includes an adjustment handle 404 and an adjustment screw 405. One end of the adjustment screw 405 is provided with an external thread and is threadedly connected to the side plate of the connecting plate 403; the other end is provided with a through hole in the vertical direction and is plugged into the adjustment screw 405.

[0034] In this embodiment, the adjusting handle 404 is a stepped post, and the diameter of the end inserted into the adjusting screw 405 matches the diameter of the through hole provided on the adjusting screw 405. This ensures that the adjusting handle 404 and the adjusting screw 405 can be plugged and unplugged, and that the adjusting handle 404 is properly positioned.

[0035] In this embodiment, the connecting plate 403 is arch-shaped with a horizontally arranged arc-shaped groove at the top, and the lower retaining plate 402 is disposed on the arc-shaped groove. This structural design ensures a tight and reliable connection between the connecting plate 403 and the lower retaining plate 402.

[0036] In this embodiment, the lower clamping plate 402 has a curved surface in the middle along its length, the curvature of which matches the curved groove on the connecting plate 403; the two sides of the lower clamping plate 402 along its length are flat, and mounting holes A406 are provided at the four corners of the flat surfaces. The mounting holes A406 are used for fixed installation with the upper clamping plate 401, and the matching of the curved surface and the curved groove improves the reliability of the connection between the lower clamping plate 402 and the connecting plate 403.

[0037] In this embodiment, the upper plate 401 has mounting platforms at both ends and an arc strip in the middle. The mounting platforms are provided with mounting holes B407 that match the mounting holes A406. The upper plate 401 is fixed to the lower plate 402 via the vertical mounting holes A406. The arc strip matches the curvature of the arc surface. The arc strip and the arc surface connect to form a complete circle, used to fix the hose A3, automatic exhaust valve B8, and hose B7 onto the Y-type filter valve 5. Two upper plates 401 are mounted on the lower plate 402.

[0038] When in use, install the high-temperature water pump with the water inlet pipe device to the application site, with the exhaust ports of the automatic air vent valve A2 and the automatic air vent valve B8 facing vertically upwards, and tighten all threads to ensure no air leakage.

[0039] Rotate the adjusting handle 404 to adjust the distance between the adjusting screw 405 and the side plate of the connecting plate 403, fix the Y-type filter valve 5 on the fixing plate, connect the first inlet 501 of the Y-type filter valve to the hose A3, connect the second inlet 502 of the Y-type filter valve to the automatic air vent valve B8 and the hose B7, with the third inlet 503 of the Y-type filter valve facing upwards, unscrew the detachable screw cap 504, fill the pipe with water through the third inlet 503 of the Y-type filter valve, and when the entire pipeline is full of water, tighten the detachable screw cap on the third inlet 503 of the Y-type filter valve again;

[0040] Start water pump 1 and use automatic air vent valves A2 and B8 to vent the gas in the pipeline, ensuring water pump flow and reducing cavitation.

[0041] Then, when water pump 1 is turned off and then restarted, the foot valve 6 draws water into the pipeline. Through the one-way valve function of the foot valve 6, the water in the pipeline is prevented from being lost after water pump 1 stops working. At this time, it is not necessary to repeatedly vent and fill water, so that one filling can be started and stopped multiple times, which is simple to operate.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
