Description

Technical Field

[0001] This utility model relates to the technical field of pressure balancing devices, and in particular to a pressure balancing device for the outlet of a high-flow pump. Background Technology

[0002] Pump outlet pressure balancing devices are important equipment widely used in the water pump industry. They are used to balance the pressure at the pump outlet to prevent excessive pressure from damaging the pipeline. However, the pump outlet pressure balancing devices currently on the market have certain limitations. When adjusting the water pressure, the sealing of the device may be insufficient, and water may flow out and splash onto the workers, causing inconvenience. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as water flowing out of the equipment and splashing onto workers when adjusting water pressure, causing inconvenience. This invention provides a pressure balancing device for the outlet of a high-flow pump.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a pressure balancing device for a high-flow-rate pump outlet, comprising a water pump, one end of which is fixedly connected to a water outlet, and one end of the water outlet is threadedly connected to a pressure balancing structure via screws. The pressure balancing structure includes an inlet, the inner wall of which is threadedly connected to the inner wall of the water outlet via screws, a water tank fixedly connected to the outer surface of the inlet, one end of which is fixedly connected to an outlet, and a baffle plate fixedly connected to the inner wall of the water tank. A first circular hole is provided, and a conical plug is slidably fitted on the inner wall of the first circular hole. A circular baffle is fixedly connected to the top of the conical plug. The outer surface of the circular baffle is in contact with the outer surface of the water baffle plate. The diameter of the circular baffle is larger than the diameter of the first circular hole. An umbrella-shaped push head is fixedly connected to the top of the circular baffle. A threaded rotating rod is fixedly connected to the top of the umbrella-shaped push head. The outer surface of the threaded rotating rod is threadedly connected to the outer surface of the water tank. A fixing ring and a rubber ring are fixedly connected to the inner wall of the water tank. The diameter of the fixing ring is larger than the diameter of the rubber ring.

[0005] In one preferred embodiment, one end of the water pump is fixedly connected to a water inlet.

[0006] In a preferred embodiment, a support plate is fixedly connected to the outer surface of the water tank.

[0007] In a preferred embodiment, the outer surface of the support plate is fixedly connected to the outer surface of the access port.

[0008] In a preferred embodiment, a sleeve is fixedly connected to the top of the water tank.

[0009] In a preferred embodiment, a second circular hole is provided on the outer surface of the sleeve.

[0010] In a preferred embodiment, the diameter of the second circular hole is larger than the diameter of the threaded rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention uses a baffle plate and a conical plug to confine the water flow to the lower half of the water tank. By rotating a threaded rod, the conical plug and the circular baffle move upward, which in turn moves the umbrella-shaped push head upward. The water flows into the upper half of the water tank through the first circular hole and out through the outlet, thus controlling the water flow. As the threaded rod rotates, the conical plug gradually moves away from the first circular hole, and the water flow gradually increases. The umbrella-shaped push head moves upward and contacts the fixing ring, simultaneously pressing the rubber ring. Under pressure, the rubber ring expands and fills the gap between itself and the fixing ring. When the conical plug completely leaves the first circular hole, the water flow reaches its maximum. The outer surface of the umbrella-shaped push head is in complete contact with the inner wall of the fixing ring, and the pressure on the rubber ring reaches its maximum. At this point, the rubber ring is fully expanded and completely fills the gap between itself and the fixing ring, preventing water from flowing out and splashing onto the workers.

[0017] 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.

[0018] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a pressure balancing device for the outlet of a large flow pump, including a water pump 1, one end of which is fixedly connected to an outlet 3, and one end of the outlet 3 is threadedly connected to a pressure balancing structure 4 by screws. The pressure balancing structure 4 includes an inlet 401, the inner wall of which is threadedly connected to the inner wall of the outlet 3 by screws, a water tank 402 fixedly connected to the outer surface of the inlet 401, an outlet 403 fixedly connected to one end of the water tank 402, a baffle plate 404 fixedly connected to the inner wall of the water tank 402, and a first circular hole formed on the outer surface of the baffle plate 404. A conical plug 406 is slidably fitted on the inner wall of the hole. A circular baffle 407 is fixedly connected to the top of the conical plug 406. The outer surface of the circular baffle 407 is in contact with the outer surface of the baffle plate 404. The diameter of the circular baffle 407 is larger than the diameter of the first circular hole. An umbrella-shaped push head 408 is fixedly connected to the top of the circular baffle 407. A threaded rotating rod 405 is fixedly connected to the top of the umbrella-shaped push head 408. The outer surface of the threaded rotating rod 405 is threadedly connected to the outer surface of the water tank 402. A fixing ring 409 and a rubber ring 410 are fixedly connected to the inner wall of the water tank 402. The diameter of the fixing ring 409 is larger than the diameter of the rubber ring 410.

[0019] In this embodiment, the water from the pump 1 is fed into the pressure balancing structure 4 through the outlet 3 via a threaded connection between the inner wall of the inlet 401 and the inner wall of the outlet 3. After entering the pressure balancing structure 4, the water first flows into the lower half of the water tank 402. The water flow is controlled by a baffle plate 404. The water flow is blocked by a first circular hole on the outer surface of the baffle plate 404 and a conical plug 406 is slidably fitted onto the inner wall of the hole. A circular baffle plate 407 limits the conical plug 406 to prevent it from flowing out. The conical plug 406 extends downwards into the water tank 402. An umbrella-shaped push head 408 is fixedly connected to the top of the circular baffle 407, causing the umbrella-shaped push head 408 to move upwards as the threaded rod 405 rotates. A fixing ring 409 and a rubber ring 410 are fixedly connected to the inner wall of the water tank 402. As the threaded rod 405 rotates, it moves upwards, causing the conical plug 406 and the umbrella-shaped push head 408 to move upwards. This creates a gap between the conical plug 406 and the first circular hole, allowing water to flow. The water flows into the upper part of the water tank 402 through the gap and flows out through the outlet 403. At this time, the outflow of water is small and will not splash upwards. As the conical plug 406 gradually moves away from the first round hole, the water flow increases and the water will splash. As the umbrella-shaped push head 408 moves upwards, the inner wall of the fixing ring 409 contacts the outer surface of the umbrella-shaped push head 408, and the rubber ring 410 is fixedly connected to the inner wall of the water tank 402. The diameter of the fixing ring 409 is larger than the diameter of the rubber ring 410, so as to limit the expansion of the rubber ring 410. Inside the rubber ring 410, as the umbrella-shaped push head 408 moves upward, the outer surface of the umbrella-shaped push head 408 contacts the outer surface of the rubber ring 410 and presses the rubber ring 410. After being pressed, the rubber ring 410 expands and gradually occupies the gap of the fixing ring 409. When the conical plug 406 completely leaves the first round hole, the outer surface of the umbrella-shaped push head 408 is in complete contact with the inner wall of the fixing ring 409. The rubber ring 410 fully expands and blocks the gap, preventing water from flowing in and preventing water from passing through the sleeve 412 and splashing onto the staff.

[0020] Example 2 like Figures 1-4 As shown, one end of the water pump 1 is fixedly connected to the water inlet 2, the outer surface of the water tank 402 is fixedly connected to the support plate 411, the outer surface of the support plate 411 is fixedly connected to the outer surface of the inlet 401, and the top of the water tank 402 is fixedly connected to the sleeve 412. The outer surface of the sleeve 412 is provided with a second circular hole, the diameter of which is larger than the diameter of the threaded rotating rod 405.

[0021] In this embodiment, water flows into the water pump 1 through the water inlet 2. A support plate 411 is fixedly connected to the outer surface of the water tank 402, and the outer surface of the support plate 411 is fixedly connected to the outer surface of the inlet 401 to achieve the support effect of the water tank 402. A sleeve 412 is fixedly connected to the top of the water tank 402, and a second round hole is opened on the outer surface of the sleeve 412 to achieve the protection effect of the threaded rotating rod 405.

[0022] Working principle: like Figures 1-4 As shown, during use, when the pressure balancing structure 4 is required, the inlet 401 is threadedly connected and fixed to the outlet 3 with screws. Water flows into the lower half of the water tank 402 through the water pump 1. Due to the obstruction of the water flow by the baffle plate 404 and the contact between the outer surface of the conical plug 406 and the inner wall of the first circular hole, the water will remain in the lower half of the water tank 402. As the water pressure gradually increases, the threaded rod 405 needs to be turned to balance the pressure. Through the rotation of the threaded rod 405, the threaded rod 405 will gradually move upward, thereby driving the conical plug 406 and the circular baffle plate 407 to move upward, and then driving the umbrella-shaped push head 408 to move upward. The outer surface of the conical plug 406 gradually leaves the inner wall of the first circular hole, and the water flows into the upper half of the water tank 402 through the first circular hole and through the outlet. Water flows out of the outlet 403 from the tank 402. As the threaded rod 405 rotates, the conical plug 406 moves further and further away from the first circular hole, and the amount of water flowing out of the first circular hole gradually increases. The outer surface of the umbrella-shaped push head 408 contacts the inner wall of the fixing ring 409 and the outer surface of the rubber ring 410, pressing the rubber ring 410. The rubber ring 410 expands under pressure and gradually occupies the gap with the fixing ring 409. When the conical plug 406 completely leaves the first circular hole, the water flow reaches its maximum. The outer surface of the umbrella-shaped push head 408 is in complete contact with the inner wall of the fixing ring 409, the pressure on the rubber ring 410 reaches its maximum, the expansion of the rubber ring 410 reaches its maximum, and the gap with the fixing ring 409 is completely filled, achieving the function of waterproofing and preventing water from flowing through the sleeve 412 and splashing onto people.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
