Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and more specifically to a water pump connector with pressure regulation function. Background Technology

[0002] Fire pump connections are devices used in conjunction with fire pumps in firefighting operations. In the event of a fire, the fire truck's pump can quickly and easily connect to the building's fire-fighting equipment through the connection's interface, supplying pressurized water to ensure sufficient pressure for extinguishing fires on different floors. This effectively solves the problem of fire trucks struggling to extinguish fires or indoor fire-fighting equipment being unable to extinguish fires due to insufficient pressure. However, existing fire pump connections have a fixed pressure, often resulting in excessively high or low water pressure, preventing water from being effectively sprayed onto the fire source, thus affecting firefighting efforts and causing irreparable damage. To address this, the inventor proposes a fire pump connection with pressure regulation. By adding a self-regulating pressure regulating valve to the connection, the fire water pressure is automatically regulated, preventing excessively high water pressure that could affect firefighting operations and effectively improving firefighting quality, thus avoiding loss of life and property.

[0003] To achieve pressure regulation of fire pump connections and facilitate stable water pressure during firefighting, Chinese Patent (Authorization Announcement No.: CN222400096U) discloses a booster-type fire pump connection. This utility model includes a main assembly comprising a base, a fire pump connection body, a connection port, and a cover. The fire pump connection body is fixed to the base, the connection port is fixed to the fire pump connection body, and the cover is disposed on the connection port. It also includes auxiliary components disposed on the main assembly, including an adjusting member, a limiting member, and a detection member. The adjusting member, the limiting member, and the detection member are all disposed on the fire pump connection body. This utility model uses the adjusting member to regulate water pressure, the limiting member to limit the adjusting member, and the detection member to detect water pressure within the fire pump connection body.

[0004] The solution still has some shortcomings in its application. Since fire protection facilities and equipment need to be in a state of readiness under normal conditions, they need to be able to respond quickly and start up quickly in the event of a fire, so that they can be used by firefighters. Therefore, the pressure regulating device of the fire pump connection also needs to be able to be activated quickly and automatically adjust according to the pressure value set before the fire starts. Otherwise, if adjustment is made after the fire starts, it is easy to cause delays in responding to the fire due to improper operation. Therefore, it is necessary to improve the fire pump connection and its connection structure so that it can realize automatic adjustment of water pressure according to the set value, so as to be used for fire fighting faster and better, and effectively improve the practicality of the fire pump connection. Utility Model Content

[0005] This utility model discloses a water pump connector with pressure regulation function, the main purpose of which is to overcome the above-mentioned shortcomings and disadvantages of the prior art:

[0006] The technical solution adopted in this utility model is as follows:

[0007] A water pump connector with pressure regulation function includes a device body and a regulating valve. The device body includes, in sequence, an interface, a connecting pipe, a check valve, a safety valve, a shut-off valve, and a fire water pipe. The regulating valve is fixed on top of the check valve. The check valve has a built-in valve groove with a water inlet in the middle. The regulating valve includes a pressure chamber at the top, a telescopic cylinder in the middle, and a telescopic rod at the bottom. The end of the telescopic rod is provided with a cover. A water inlet pipe is provided on one side of the pressure chamber and an elastic plate is provided at the bottom. A pressure block is provided on the top of the telescopic cylinder. A connecting rod is provided between the pressure block and the elastic plate. The elastic plate presses down on the pressure block to drive the telescopic rod downward.

[0008] Furthermore, the end of the water inlet pipe extends into the inside of the fire water pipe and is equipped with a pressure sensor.

[0009] Furthermore, a controller is installed in the middle section of the water inlet pipe, and the controller has a built-in control valve, which is connected to the control valve.

[0010] Furthermore, a pressure gauge is provided on one side of the controller.

[0011] Furthermore, the telescopic cylinder has a cylinder body in the middle, a fixing block at the bottom of the cylinder body, and a spring between the fixing block and the pressure block.

[0012] Furthermore, the telescopic rod drives the cover downwards to movably cover the water inlet.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention firstly adds a regulating valve to the top of the shut-off valve to automatically regulate and control the water flow pressure of the equipment body, facilitating stable water pressure during firefighting and preventing water from failing to reach the flamethrower due to excessive or insufficient water pressure. Secondly, the check valve within the equipment body has a built-in valve groove. Water flow is controlled by the movable cover at the end of the regulating valve's telescopic rod and the inlet. The vertical movement of the telescopic rod is generated by the contact between the top pressure block and the elastic plate in the pressure chamber. The bending pressure of the elastic plate is generated by water being injected into the pressure chamber through the inlet pipe. Whether water enters or leaves the inlet pipe is controlled by… The control valve achieves this, and the structural design is quite ingenious. Finally, when the water pressure sensed by the pressure sensor reaches the set value, the control valve is automatically opened, allowing fire water to enter the pressure chamber. The elastic plate at the bottom of the pressure chamber bends downward, driving the pressure block downward. The downward movement of the pressure block drives the telescopic rod downward, thereby driving the cover to approach the water inlet, reducing the water flow rate at the inlet and decreasing the water pressure on one side of the fire water pipe, thus achieving automatic pressure regulation. This utility model has a novel structure and ingenious design, enabling automatic regulation of water pressure without manual operation. It is highly practical and suitable for widespread application. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, a water pump connector with pressure regulation function includes a device body 1 and a regulating valve 2. The device body 1 includes, in sequence, an interface 3, a connecting pipe 4, a check valve 5, a safety valve 6, a shut-off valve 7, and a fire water pipe 8. The regulating valve 2 is fixed to the top of the check valve 5. The check valve 5 has a valve groove 51 inside, and a water inlet 52 is provided in the middle of the valve groove 51. The regulating valve 2 includes a pressure chamber 21 at the top, a telescopic cylinder 22 in the middle, and a telescopic rod 23 at the bottom. The telescopic rod 23 has a cover 24 at its end. A water inlet pipe 25 is provided on one side of the pressure chamber 21 and an elastic plate 9 is provided at the bottom. A pressure block 10 is provided at the top of the telescopic cylinder 22. A connecting rod 101 is provided between the pressure block 10 and the elastic plate 9. The elastic plate 9 presses down on the pressure block 10 to drive the telescopic rod 23 downward.

[0020] Furthermore, the end of the water inlet pipe 25 extends to the inside of the fire water pipe 8 and is equipped with a pressure sensor 11.

[0021] Furthermore, a controller 12 is installed in the middle section of the water inlet pipe 25. The controller 12 has a built-in control valve (not shown in the schematic diagram due to viewing angle). The controller 12 is connected to the control valve.

[0022] Furthermore, a pressure gauge 13 is provided on one side of the controller 12.

[0023] Furthermore, the telescopic cylinder 22 has a cylinder body in the middle, and a fixing block 14 is provided at the bottom of the cylinder body. A spring 15 is provided between the fixing block 14 and the pressure block 10.

[0024] Furthermore, the telescopic rod 23 drives the cover 24 downward to movably cover the water inlet 52.

[0025] [Example]

[0026] First, in the event of a fire, the fire truck injects fire water from interface 3 of the equipment body 1. The fire water enters through the inlet 52 of the valve groove 51 on the check valve 5, and then passes through the safety valve 6 and the shut-off valve 7 to reach the fire water pipe 8. The pressure sensor 11 in the fire water pipe 8 senses the water pressure and displays it through the pressure gauge 13. A small portion of the fire water simultaneously flows into the inlet pipe 25 to the control valve side. Then, the controller 12 sets the pressure value for opening the control valve. When the pressure value sensed by the pressure sensor 11 reaches the controller's pressure value... When the pressure value set at 12 is reached, the control valve opens, and fire water flows from the control valve to the pressure chamber 21 at the top of the regulating valve 2. Water is injected into the pressure chamber 21 to generate pressure. Finally, the elastic plate 9 at the bottom of the pressure chamber 21 is bent by the pressure and abuts against the pressure block 10, pressing the pressure block 10 downward. The downward pressure of the pressure block 10 drives the telescopic rod 23 downward, and the downward telescopic rod 23 drives the cover 24 downward to partially cover the inlet 52, thereby reducing the water flow through the inlet 52, reducing the water flow in the fire water pipe 8, and reducing the pressure accordingly, thus achieving automatic pressure regulation.

[0027] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0028] This invention firstly adds a regulating valve to the top of the shut-off valve to automatically regulate and control the water flow pressure of the equipment body, facilitating stable water pressure during firefighting and preventing water from failing to reach the flamethrower due to excessive or insufficient water pressure. Secondly, the check valve within the equipment body has a built-in valve groove. Water flow is controlled by the movable cover at the end of the regulating valve's telescopic rod and the inlet. The vertical movement of the telescopic rod is generated by the contact between the top pressure block and the elastic plate in the pressure chamber. The bending pressure of the elastic plate is generated by water being injected into the pressure chamber through the inlet pipe. Whether water enters or leaves the inlet pipe is controlled by… The control valve achieves this, and the structural design is quite ingenious. Finally, when the water pressure sensed by the pressure sensor reaches the set value, the control valve is automatically opened, allowing fire water to enter the pressure chamber. The elastic plate at the bottom of the pressure chamber bends downward, driving the pressure block downward. The downward movement of the pressure block drives the telescopic rod downward, thereby driving the cover to approach the water inlet, reducing the water flow rate at the inlet and decreasing the water pressure on one side of the fire water pipe, thus achieving automatic pressure regulation. This utility model has a novel structure and ingenious design, enabling automatic regulation of water pressure without manual operation. It is highly practical and suitable for widespread application.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
