Description

Technical Field

[0001] This utility model belongs to the field of water pump valve disassembly and assembly technology, and more specifically, it relates to a water pump valve. Background Technology

[0002] A water pump valve is a mechanical valve device used to control the water flow at the inlet and outlet of a water pump. It mainly includes various types such as gate valves, check valves, and regulating valves. Water pump valves are widely used in various occasions that require liquid transportation. They can effectively regulate the pressure and flow rate of the fluid medium, prevent backflow of the medium, ensure the normal operation of the water pump, and protect the equipment from damage. Currently, the installation of water pump valves typically requires aligning the flange through-hole structures at the inlet and outlet of the water pipe with the through-hole structures of two sets of pipe flanges, then inserting multiple sets of bolts into the through-holes of the water pump valve flange and the pipe flange, and finally screwing multiple sets of nuts onto the threaded structures on the outer surfaces of the bolts. The nuts, together with the bolts, compress and clamp the water pump valve flange and the pipe flange, ensuring that the rubber gaskets on the flanges of the water pump valve flange and the pipe flange fit tightly, thus completing the sealed assembly of the water pump valve and the pipeline. As can be seen, the traditional installation structure of water pump valves and pipelines is relatively complex. Whether disassembling or assembling the water pump valve and pipeline, multiple sets of nuts and bolts need to be tightened, which seriously reduces the efficiency of water pump valve and pipeline installation and disassembly. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a water pump valve to solve the problem of low installation and disassembly efficiency of water pump valves and pipelines due to the need to tighten multiple sets of nuts and bolts during the disassembly and assembly process of traditional water pump valves.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1-7 As shown, this utility model provides a water pump valve, including a valve 1; a valve body 2 is installed at the bottom of the valve 1; it also includes a connecting pipe 3; a sleeve 11 is welded to the outer side of the connecting pipe 3, a plug plate 8 is welded to one end of the connecting pipe 3, and a flange 12 is welded to the other end of the connecting pipe 3; the valve 1 is installed on the upper side of the valve body 2, and locking discs 9 are welded to the outer side of the valve body 2 near the left and right ends, with sealing rubber gaskets 7 adhered to the locking discs 9; an installation sleeve 4 is slidably connected to the outer side of the valve body 2, and a limit plate 5 is slidably connected to the outer side of the valve body 2.

[0022] In this embodiment, the plug-in plate 8 is a circular ring-shaped structure, and there are two sets of plug-in plates 8. Each set of plug-in plates 8 has six sets of L-shaped through grooves on its left side. The L-shaped through grooves of the plug-in plate 8 are arranged in a ring array around the horizontal central axis of the plug-in plate 8. The plug-in plate 8 has six sets of small through holes. A sealing rubber gasket 7 is bonded to the circular ring-shaped structure of the plug-in plate 8. The sealing rubber gasket 7 surrounds the outside of the water inlet and water outlet of the valve body 2. When the plug-in plate 8 and the locking plate 9 are clamped and fitted together, the sealing rubber gasket 7 seals the contact surface between the plug-in plate 8 and the locking plate 9.

[0023] In this embodiment, the locking disc 9 is a circular ring-shaped structure. Locking rods 10 are welded to the side of the circular ring-shaped structure of the locking disc 9. There are six sets of locking rods 10, and each set of locking rods 10 is an L-shaped structure. The locking rods 10 are arranged in a ring array around the horizontal central axis of the locking disc 9. The locking rods 10 are inserted into the L-shaped through slot of the plug-in disc 8. When the small through hole of the plug-in disc 8 and the small through hole of the locking disc 9 are rotated to face each other, the bent part of the L-shaped structure of the locking rod 10 fits against the ring-shaped side of the plug-in disc 8, and the locking rod 10 limits and locks the plug-in disc 8 to move left and right.

[0024] In this embodiment, there are two sets of limiting discs 5. Each set of limiting discs 5 has a circular through hole at its center. The water outlet pipe and water inlet pipe of the valve body 2 are respectively inserted into the circular through hole of the limiting disc 5. Six sets of protruding pillars 6 are welded to the outside of the circular through hole of the limiting disc 5. The protruding pillars 6 are arranged in a ring array around the horizontal central axis of the limiting disc 5. The protruding pillars 6 of the limiting disc 5 are inserted into the six sets of small through holes of the plug-in disc 8 and the six sets of small through holes of the locking disc 9. The protruding pillars 6 of the limiting disc 5 rotate and limit the locking of the plug-in disc 8 and the locking disc 9 to prevent the plug-in disc 8 and the locking disc 9 from rotating and unlocking, and ensure that the locking rod 10 welded to the plug-in disc 8 is stably inserted into the L-shaped through groove of the locking disc 9.

[0025] In this embodiment, there are two sets of mounting sleeves 4. Each set of mounting sleeves 4 is a cylindrical structure. The outer side of the mounting sleeve 4 is densely covered with a large number of vertical stripes to increase the friction between the outer side of the mounting sleeve 4 and the hand, making it easy for pipe installers to rotate the mounting sleeve 4 for assembly and disassembly. The inner side of the cylinder of the mounting sleeve 4 is provided with a threaded structure.

[0026] In this embodiment, the outer side of the sleeve 11 is provided with a threaded structure. The outer side of the sleeve 11 is threaded and screwed into the inner side of the mounting sleeve 4. During the process of the mounting sleeve 4 engaging and tightening at the outer side of the sleeve 11, the insertion plate 8 and the mounting sleeve 4 clamp and squeeze the limiting plate 5 and the locking plate 9 from left to right, so that the protrusion 6 of the limiting plate 5 is stably inserted into the small through hole of the insertion plate 8 and the locking plate 9, preventing the protrusion 6 from disengaging from the through hole of the insertion plate 8 and the locking plate 9, and ensuring that the protrusion 6 locks the rotational movement of the insertion plate 8 and the locking plate 9.

[0027] The specific usage and function of this embodiment are as follows:

[0028] When installing the water pump valve, the six sets of locking rods 10 welded to the locking disc 9 are first inserted into the L-shaped through groove of the connector 8. Then, the locking disc 9 is rotated until the small through hole of the locking disc 9 is aligned with the small through hole of the connector 8. At this time, the bent part of the L-shaped locking rod 10 fits against the side of the connector 8. The L-shaped structure of the locking rod 10 locks the connector 8 by moving it left and right, so that the sealing rubber gasket 7 bonded to the connector 8 and the sealing rubber gasket 7 bonded to the locking disc 9 fit tightly together. Then, the limiting disc 5 is manually pushed. The limiting disc 5 drives the protrusion 6 to be inserted into the small through hole of the locking disc 9 and the small through hole of the connector 8 in sequence. At this time, the protrusion 6 rotates and locks the locking disc 9 and the connector 8. Then, the mounting sleeve 4, which is slidably connected to the outer side of the valve body 2, is connected to the threaded structure on the outer side of the sleeve 11. The mounting sleeve 4 is manually rotated. Due to the engagement of the threads on the inner side of the mounting sleeve 4, the locking sleeve 4 will rotate and lock the valve body 2. The sleeve 11 is connected to the threaded structure on the outer side of the sleeve 11. The sleeve 11 is inserted into the inner side of the cylindrical structure of the mounting sleeve 4. The mounting sleeve 4 and the plug plate 8 clamp the limiting plate 5 and the locking plate 9 in opposite directions to prevent the protrusion 6 welded to the limiting plate 5 from disengaging from the small through hole of the locking plate 9 and the small through hole of the plug plate 8. This completes the quick assembly of the connecting pipe 3 and the valve body 2. When disassembling the water pump valve, rotate the mounting sleeve 4 in the opposite direction and unscrew the sleeve 11 to the outside of the mounting sleeve 4. Then, manually pull the limiting plate 5. The limiting plate 5 drives the protrusion 6 to disengage from the small through hole of the locking plate 9 and the small through hole of the plug plate 8. Then, rotate the plug plate 8 in the opposite direction until the bent part of the locking rod 10 disengages from the side of the plug plate 8. At this time, the bent part of the locking rod 10 is opposite to the L-shaped through groove of the plug plate 8. Then, pull the locking rod 10 outward from the L-shaped through groove of the plug plate 8 to complete the quick disassembly of the connecting pipe 3 and the valve body 2.

[0029] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technology; any method that achieves the desired effect can be implemented. The valve 1 and sealing rubber gasket 7 mentioned above are common commercially available components. When purchasing and using them, simply follow the instruction manual purchased with the product to connect them for operation; therefore, further details are omitted here.
