Description

Technical Field

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

[0002] A booster pump is a pump device used to increase water pressure, mainly to solve the problem of insufficient water pressure. Booster pumps play a vital role in modern life and industry. They can not only increase the pressure of water flow and ensure the stability of the water supply system, but also meet various water demand. The working principle of booster pumps is based on the principles of fluid mechanics.

[0003] However, existing technologies have some problems: the high-pressure one-way outlet valve in the existing booster pump outlet structure is usually fixed between the high-pressure outlet chamber and the pump body. Since the high-pressure one-way outlet valve is a vulnerable part, it needs to be inspected and maintained from time to time. When the device is maintained, the entire high-pressure outlet chamber needs to be disassembled in order to complete the maintenance and installation of the high-pressure one-way outlet valve. Frequent disassembly and assembly causes inconvenience and difficulty for the staff and results in low work efficiency. Therefore, we propose an outlet 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 outlet structure device for a booster water pump, which facilitates the maintenance work of the staff and improves work efficiency by quickly disassembling and assembling the high-pressure one-way water outlet valve.

[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, this utility model provides a water outlet structure device for a booster water pump, including a pump body 6, a high-pressure water outlet valve body 3 disposed on the pump body 6, four assembly steps 3.8 formed on the outer surface of the high-pressure water outlet valve body 3, threaded holes 3.7 located in the assembly steps 3.8 formed on the high-pressure water outlet valve body 3, fastening screws 3.9 disposed in the threaded holes 3.7, the pump body 6 and the high-pressure water outlet valve body 3 are connected by fastening screws 3.9, and sealing threaded assembly holes 3.10 are formed on the high-pressure water outlet valve body 3 located between the four assembly steps 3.8. The high-pressure outlet valve body 3 has interconnected pump body cavity 3.1, water valve cavity 3.3, high-pressure sealing cavity 3.4 and high-pressure outlet cavity 3.6. The high-pressure one-way outlet valve 4 is movably installed inside the water valve cavity 3.3. The high-pressure outlet valve body 3 has a water valve positioning step 3.2 located at the connection between the pump body cavity 3.1 and the water valve cavity 3.3. The high-pressure positioning plug 5 is installed inside the sealing thread assembly hole 3.10. The high-pressure one-way outlet valve 4 is positioned and installed inside the water valve cavity 3.3 by the high-pressure positioning plug 5 and the water valve positioning step 3.2.

[0021] By removing the high-pressure positioning plug 5 from the plug thread assembly hole 3.10, the high-pressure one-way water outlet valve 4 can be removed from the water valve cavity 3.3, which facilitates the maintenance and inspection of the high-pressure one-way water outlet valve 4 without having to disassemble the entire cavity, making it convenient and quick.

[0022] Furthermore, a high-pressure connector 2 is threadedly connected to the right side of the high-pressure outlet valve body 3, and a high-pressure outlet pipe 1 is threadedly connected to the right end of the high-pressure connector 2.

[0023] The water pressurized by the pump body 6 can be discharged outward through the high-pressure outlet pipe 1 connected to the high-pressure connector 2.

[0024] 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 high-pressure outlet 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 top is positioned on the high-pressure outlet valve body 3 by the hexagonal step 5.1, and the bottom of the high-pressure positioning plug 5 abuts against the top of the high-pressure one-way outlet valve 4.

[0025] When repairing and inspecting the high-pressure one-way outlet valve 4, only the high-pressure positioning plug 5 needs to be removed to take out the high-pressure one-way outlet valve 4 for repair and inspection, which is convenient and quick.

[0026] Furthermore, a high-pressure sealing gasket 5.4 is fixedly installed at the bottom of the high-pressure outlet valve body 3, and the high-pressure sealing gasket 5.4 is located at the connection between the pump body cavity 3.1 and the pump body 6.

[0027] The design of the high-pressure sealing gasket 5.4 can improve the sealing effect at the connection between the high-pressure outlet valve body 3 and the pump body 6, ensuring the normal drainage operation of the pump body 6.

[0028] Furthermore, the high-pressure one-way water outlet valve 4 is equipped 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 bottom of the high-pressure one-way water outlet valve 4 abuts against the water valve positioning step 3.2.

[0029] 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 outlet cavity 3.6 and the pump body cavity 3.1.

[0030] When pump body 6 is running, under the pressure of incoming water, the high-pressure one-way outlet valve 4 is pushed by the valve core 4.4, compressing the spring 4.5 and opening the valve. This allows high-pressure water to pass through the pump body 6 into the pump cavity 3.1, then into the high-pressure one-way outlet valve 4, and finally into the pump body 6 via the high-pressure connector 2. This completes the process of high-pressure water flowing from the pump body 6 into the high-pressure outlet pipe 1 and outwards. When maintenance or repair is required, only the high-pressure positioning seal 5 needs to be removed. The high-pressure one-way outlet valve 4 can be removed from the water valve cavity 3.3 by removing it from the threaded assembly hole 3.10. This facilitates the maintenance and inspection of the high-pressure one-way outlet valve 4 without disassembling the entire cavity. When installing the high-pressure one-way outlet valve 4, simply insert it into the water valve cavity 3.3 and tighten the high-pressure positioning plug 5 into the threaded assembly hole 3.10 so that the high-pressure one-way outlet valve 4 abuts against the water valve positioning step 3.2. This is convenient and quick, improving the efficiency of maintenance or repair of the high-pressure one-way outlet valve 4.

[0031] 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.
