Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and in particular relates to a water inlet structure device for a booster water pump. Background Technology

[0002] A booster pump is a device used to increase water pressure. It meets the water demand in specific situations by increasing the water pressure. Its working principle is that the booster pump uses the low-pressure fluid at the large-area piston end to drive the generation of high-pressure fluid at the small-area piston end. When the piston moves back and forth quickly, the liquid is drawn in through the water inlet structure and discharged outward by the piston thrust, thereby increasing the speed and pressure of the water flow.

[0003] However, existing technologies have some problems: existing booster pumps usually fix the one-way inlet valve in the inlet structure between the inlet chamber and the pump body. When the device is maintained, the entire inlet chamber needs to be disassembled in order to complete the maintenance and installation of the one-way inlet valve. However, the one-way inlet valve is a vulnerable part and needs to be inspected and maintained from time to time. Frequent disassembly and assembly of the entire inlet chamber causes inconvenience and difficulty for the staff. Therefore, we propose an inlet structure device for booster pumps. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a water inlet structure device for booster water pumps, which facilitates the maintenance and repair work of staff by quickly disassembling and assembling the one-way water inlet valve.

[0005] This utility model is implemented as follows: a water inlet structure device for a booster water pump includes a pump body, on which an inlet valve body is provided. The outer surface of the inlet valve body has four steps, and the inlet valve body has threaded holes located in the steps. Fastening screws are provided in the threaded holes. The pump body and the inlet valve body are connected by fastening screws. The interior of the inlet valve body has a horizontally connected high-pressure water inlet chamber, a water valve positioning step, a water valve chamber, and a high-pressure sealing chamber. The inlet valve body also has a pump body cavity communicating with the water valve chamber. A one-way water inlet valve is movably installed inside the water valve chamber. The interior of the inlet valve body has a water valve positioning step located at the connection between the high-pressure water inlet chamber and the water valve chamber. A high-pressure positioning plug is provided on the left side of the inlet valve body. The one-way water inlet valve is positioned and installed inside the water valve chamber by the high-pressure positioning plug and the water valve positioning step.

[0006] Optionally, a high-pressure connector is threaded to the right side of the water inlet valve body, and a high-pressure water inlet pipe is threaded to the right end of the high-pressure connector.

[0007] Optionally, the high-pressure positioning plug is provided with a hexagonal step, fastening threads, and a high-pressure sealing assembly. The main body of the high-pressure positioning plug is disposed in the high-pressure sealing cavity, and the high-pressure sealing assembly cooperates with the high-pressure sealing cavity to achieve sealing. The inlet valve body has a threaded cavity located inside the high-pressure sealing cavity. The main body of the high-pressure positioning plug is fixed in the high-pressure sealing cavity by the cooperation of the fastening threads and the threaded cavity. The left side is positioned on the left side of the inlet valve body by the hexagonal step, and the right side of the high-pressure positioning plug abuts against the left side of the one-way inlet valve.

[0008] Optionally, a high-pressure sealing gasket is fixedly installed at the bottom of the water inlet valve body, and the high-pressure sealing gasket is located at the connection between the pump body cavity and the pump body.

[0009] Optionally, the one-way inlet valve is provided with a valve cover, a one-way high-pressure sealing assembly, a valve body, a valve core, and a spring. The spring is disposed between the valve core and the valve body, and the right side of the one-way inlet valve abuts against the valve positioning step.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model, by setting up a one-way inlet valve, a high-pressure positioning plug, a valve positioning step, and a valve cavity, allows workers to easily remove the one-way inlet valve for maintenance or repair when needed. Simply remove the high-pressure positioning plug from the inlet valve body, and the one-way inlet valve can be taken out of the valve cavity for repair and inspection. When installing the one-way inlet valve, after inserting it into the valve cavity, tightening the high-pressure positioning plug ensures that the right side of the one-way inlet valve abuts against the valve positioning step, completing the installation quickly and conveniently. It eliminates the need to disassemble the entire cavity, facilitating maintenance and repair work.

[0019] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] like Figures 1 to 5 As shown in the figure, the present invention provides a water inlet structure device for a booster water pump, including a pump body 6, an inlet valve body 3 on the pump body 6, four steps 3.8 on the outer surface of the inlet valve body 3, threaded holes 3.7 in the steps 3.8 on the inlet valve body 3, and fastening screws 3.9 in the threaded holes 3.7. The pump body 6 and the inlet valve body 3 are connected by the fastening screws 3.9. The interior of the inlet valve body 3 has a horizontally communicating high-pressure water inlet chamber 3.1 and a water valve positioning step 3. 2. The water valve chamber 3.3 and the high-pressure sealing chamber 3.4 are provided. The inlet valve body 3 is also provided with a pump body chamber 3.6 that communicates with the water valve chamber 3.3. A one-way inlet valve 4 is movably installed inside the water valve chamber 3. The inlet valve body 3 is provided with a water valve positioning step 3.2 located at the connection between the high-pressure inlet chamber 3.1 and the water valve chamber 3.3. A high-pressure positioning plug 5 is provided on the left side of the inlet valve body 3. The one-way inlet valve 4 is positioned and installed inside the water valve chamber 3.3 by the high-pressure positioning plug 5 and the water valve positioning step 3.2.

[0021] Furthermore, a high-pressure connector 2 is threadedly connected to the right side of the inlet valve body 3, and a high-pressure inlet pipe 1 is threadedly connected to the right end of the high-pressure connector 2.

[0022] By connecting the high-pressure connector 2 and the high-pressure water inlet pipe 1 to the water inlet valve body 3, the pump body 6 can draw external water from the water source through the high-pressure connector 2 and the high-pressure water inlet pipe 1 on the water inlet valve body 3.

[0023] Furthermore, the high-pressure positioning plug 5 is provided with a hexagonal step 5.1, a fastening thread 5.2, and a high-pressure sealing assembly 5.3. The main body of the high-pressure positioning plug 5 is set in the high-pressure sealing cavity 3.4, and the high-pressure sealing assembly 5.3 cooperates with the high-pressure sealing cavity 3.4 to achieve sealing. The inlet valve body 3 has a threaded cavity 3.5 located inside the high-pressure sealing cavity 3.4. The main body of the high-pressure positioning plug 5 is fixed in the high-pressure sealing cavity 3.4 by the cooperation of the fastening thread 5.2 and the threaded cavity 3.5. The left side is positioned on the left side of the inlet valve body 3 by the hexagonal step 5.1, and the right side of the high-pressure positioning plug 5 abuts against the left side of the one-way inlet valve 4.

[0024] When repairing and inspecting the one-way inlet valve 4, only the high-pressure positioning plug 5 needs to be removed to take out the one-way inlet valve 4 for repair and inspection, which is convenient and quick, without having to remove the entire cavity.

[0025] Furthermore, a high-pressure sealing gasket 5.4 is fixedly installed at the bottom of the inlet valve body 3, and the high-pressure sealing gasket 5.4 is located at the connection between the pump body cavity 3.6 and the pump body 6.

[0026] The design of the high-pressure sealing gasket 5.4 can improve the sealing effect at the connection between the inlet valve body 3 and the pump body 6, ensuring the normal use of the pump body 6.

[0027] Furthermore, the one-way inlet valve 4 is provided with a water valve cover 4.1, a one-way high-pressure sealing assembly 4.2, a water valve body 4.3, a water valve core 4.4, and a spring 4.5. The spring 4.5 is located between the water valve core 4.4 and the water valve body 4.3, and the right side of the one-way inlet valve 4 abuts against the water valve positioning step 3.2.

[0028] The spring force of spring 4.5 causes the water valve core 4.4 and water valve cover 4.1 to press tightly together, so that the water valve is normally closed. The one-way high pressure sealing component 4.2 cooperates with the high pressure sealing cavity 3.4 to completely seal the pressure between the high pressure inlet cavity 3.1 and the pump body cavity 3.6.

[0029] When the pump body 6 is running, under the pressure of the incoming water, the one-way inlet valve 4's valve core 4.4 moves to the left to compress the spring 4.5, opening the valve and allowing water to enter the one-way inlet valve 4 from the high-pressure inlet chamber 3.1, then into the pump body chamber 3.6, and finally into the pump body 6. This process realizes the entry of high-pressure water into the pump body 6 through the high-pressure inlet pipe 1. When the operator needs to remove the one-way inlet valve 4 for maintenance or repair, they only need to remove the high-pressure positioning plug 5 from the inlet valve body 3 to remove the one-way inlet valve 4 from the valve chamber 3.3 for maintenance and inspection. When installing the one-way inlet valve 4, after installing it into the valve chamber 3.3, tightening the high-pressure positioning plug 5 so that the right side of the one-way inlet valve 4 abuts against the valve positioning step 3.2 completes the installation of the one-way inlet valve 4. This is convenient and quick, as it does not require disassembling the entire chamber, making maintenance and repair work easier for the operator.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
