Description

Technical Field

[0001] This utility model relates to the field of water pump valve technology, specifically a valve for a circulating water pump. Background Technology

[0002] The valve of a circulating water pump is an intelligent regulating device, which is usually used in industrial circulation systems to regulate the circulation flow and pressure. It controls parameters such as fluid speed, direction and pressure by changing the valve opening, thereby achieving precise control of the circulation system.

[0003] According to patent number CN202220423945.4, a valve for a circulating water pump includes a circulating water pump with a valve installed on it. The valve is connected to an oil pump motor, which is connected to an oil cylinder. The oil cylinder has an oil discharge port, which is connected to a solenoid valve. The solenoid valve has a valve core inside it, which slides within the valve. The sliding direction of the valve core is perpendicular to the opening direction of the oil discharge port.

[0004] The above solution still has certain technical defects in actual use. During use, since the filter device is installed at the connection port at the end of the valve, when the filter device needs to be cleaned or replaced after a long period of use, the connection between the valve and the pipeline or pump body must be disassembled first before the filter device can be disassembled, replaced or cleaned. This greatly reduces the efficiency of disassembling and assembling the filter device. Therefore, we propose a valve for the circulating water pump. Utility Model Content

[0005] The purpose of this invention is to provide a valve for a circulating water pump to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve for a circulating water pump, comprising a valve body and pipes located on both sides of the valve body, one pipe being an inlet pipe and the other an outlet pipe, wherein each pipe has an installation groove, and the opening of the installation groove is located on the outer surface of the pipe, each installation groove contains a filter device, and slots are provided on both sides of the pipe located in the installation groove; each filter device is connected to a corresponding pipe, and the filter device includes a cover plate, a sealing plate, and a filter plate assembly; the cover plate covers the opening of the installation groove; the sealing plate is located on the side of the cover plate facing the outlet pipe. On one side of the mounting groove, an elastic clamping assembly is provided between the sealing plate and the cover plate. The elastic clamping assembly is used to press the sealing plate against the edge of the opening of the mounting groove so that the sealing plate and the opening edge of the mounting groove are sealed together. The filter plate assembly includes a filter screen assembly installed on the side of the cover plate away from the cover plate. The filter screen assembly includes a filter screen, which is used to extend into the pipe so that the filter screen covers the through hole of the pipe. Insert plates are provided on the side of the cover plate facing the mounting groove and correspond one-to-one with the slots. Each pair of corresponding insert plates and slots are inserted into each other and the insert plates and slots are interlocked. Preferably, fixed clamping plates are fixedly installed on both sides of the end of the insert plate away from the cover plate. A sliding groove is formed inside the insert plate, and a movable clamping plate is slidably connected in the sliding groove. The two ends of the movable clamping plate extend to the outside of the sliding groove. Both ends of the fixed clamping plate and the movable clamping plate are provided with inclined surfaces, and the inclined surfaces at both ends of the fixed clamping plate are opposite to and reversed from the inclined surfaces at both ends of the movable clamping plate. A locking block is slidably connected to the inner wall surface on both sides of the slot. The end of the locking block away from the inner wall of the slot is provided with an inclined surface, and the inclined surface faces the opening of the slot. The locking block, the fixed clamping plate, and the movable clamping plate can cooperate with each other to make the insert plate engage in the slot.

[0007] Based on the above technical features, in the specific use of the valve in the circulating water pump, the insert plate is inserted into the slot, and the filter device is installed and fixed in the mounting groove through the cooperation of the locking block, the fixed locking plate, and the movable locking plate. During this process, the elastic clamping component squeezes the sealing plate, and the sealing plate can achieve a sealing fit with the opening edge of the mounting groove under the action of the elastic clamping component, preventing leakage. When it is necessary to disassemble or assemble the filter device, simply press down on the cover plate to move the movable locking plate down until the movable locking plate merges with the fixed locking plate, and then pull the filter device upward to apply pressure to the locking block, causing it to retract until the locking block is completely retracted into the inner wall of the slot, thus releasing the insert plate from the locking state. This greatly improves the convenience of disassembling and assembling the filter device and effectively reduces the difficulty of disassembling and assembling the filter device.

[0008] In this preferred embodiment, the elastic clamping assembly includes a corrugated rubber sleeve and a clamping spring disposed inside the corrugated rubber sleeve. The corrugated rubber sleeve is disposed between the cover plate and the sealing plate by adhesive bonding, and the two ends of the clamping spring are respectively fixed to the cover plate and the sealing plate.

[0009] Based on the above technical features, the sealing plate can be pressed firmly onto the mounting groove under the action of the compression spring, achieving tight contact between the outer periphery of the sealing plate and the inner wall of the mounting groove, thereby improving the sealing performance between the filter device and the mounting groove and preventing leakage.

[0010] In this preferred embodiment, a return spring is provided between the movable locking plate and the top wall of the slide groove. The return spring is used for the movable locking plate to slide telescopically relative to the fixed locking plate within the slide groove. More preferably, a locking spring is provided at one end of the locking block extending into the slot, allowing the locking block to slide telescopically within the slot via the locking spring.

[0011] Based on the above technical features, the setting of reset spring and snap-fit ​​spring makes it easier to switch between snap-fit ​​and de-snap between the insert plate and the slot, thereby more effectively reducing the difficulty of disassembling and assembling the filter device.

[0012] In a preferred embodiment of this technical solution, the filter device further includes a sealing gasket, which is bonded to the inner wall surface of the mounting groove. More preferably, the sealing plate is made of rubber.

[0013] Based on the above technical features, the rubber sealing plate has excellent elasticity and shock absorption performance, which can effectively reduce the impact of water flow on the sealing effect between the filter plate and the mounting groove, thereby ensuring tight contact between the rubber sealing plate and the sealing gasket and improving the sealing effect between the filter device and the mounting groove.

[0014] In a preferred embodiment of this technical solution, the filter plate assembly further includes a filter plate, which is installed on the side of the cover plate away from the cover plate, and the filter screen is installed on the filter plate. More preferably, the filtration device further includes a sealing sleeve, which is glued to the outer periphery of the filter plate and sealed thereto.

[0015] Based on the above technical features, a sealing sleeve is fitted around the outer periphery of the filter plate, which ensures the sealing between the filter plate and the inner wall of the installation groove when the filter plate is inserted into the installation groove.

[0016] In a preferred embodiment of this technical solution, the filtration device further includes a handle, which is disposed opposite to the filter plate and is fixedly installed on the top of the cover plate.

[0017] Based on the above technical features, the handle design makes it convenient for staff to lift or press the filter device. Attached Figure Description

[0026] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0028] like Figure 1 and Figure 5 As shown, this utility model provides a technical solution: a valve for a circulating water pump, including a valve body 1 and pipes located on both sides of the valve body 1, one pipe being an inlet pipe and the other being an outlet pipe. The valve body 1, the inlet pipe, and the outlet pipe are integrally connected, and the interiors of the inlet pipe and the outlet pipe are interconnected. Each pipe has an installation groove 2 (i.e., an installation groove is opened on the inlet pipe, and a corresponding installation groove is opened on the outlet pipe), and the opening of the installation groove 2 is located on the outer surface of the pipe. Each installation groove 2 contains a filter device, and slots 4 are opened on both sides of the pipe located in the installation groove 2. Each filter device is connected to the corresponding pipe, and the filter device includes a cover plate 9, a sealing plate 16, and a filter plate assembly.

[0029] Specifically, such as Figure 1 As shown, when the filter device is inserted into the mounting slot 2 of the corresponding pipe, the cover plate 9 covers the opening of the mounting slot 2.

[0030] like Figures 2 to 4 As shown, the sealing plate 16 is located on the side of the cover plate 9 facing the mounting groove 2. An elastic pressing assembly is provided between the sealing plate 16 and the cover plate 9. The elastic pressing assembly is used to press the sealing plate 16 against the edge of the opening of the mounting groove 2, so that the sealing plate 16 and the edge of the opening of the mounting groove 2 are sealed together. Preferably, in this embodiment of the present invention, the elastic pressing assembly consists of a corrugated rubber sleeve 17 and a compression spring 18. The compression spring 18 is disposed inside the corrugated rubber sleeve 17, which is glued between the cover plate 9 and the sealing plate 16. The two ends of the compression spring 18 are respectively fixed to the cover plate 9 and the sealing plate 16. Under the action of the compression spring 18, the sealing plate 16 can be pressed firmly onto the mounting groove 2, achieving tight contact between the outer periphery of the sealing plate 16 and the inner wall of the mounting groove 2, thereby improving the sealing performance between the filter device and the mounting groove 2 and preventing leakage.

[0031] like Figures 2 to 4 As shown, the filter plate assembly includes a filter screen assembly and a filter plate 7. The filter screen assembly is installed on the side of the cover plate 9 away from the cover plate 9. The filter screen assembly includes a filter screen 19. The filter plate 7 is installed on the side of the cover plate 9 away from the cover plate 9. The filter screen 19 is installed on the filter plate 7 and is used to extend into the pipe so that the filter screen 19 covers the through hole of the pipe.

[0032] Furthermore, such as Figure 2As shown, the filtration device also includes a sealing gasket 3 and a sealing sleeve 8. The sealing gasket 3 is glued to the inner wall surface of the mounting groove 2, and the sealing sleeve 8 is glued to the outer periphery of the filter plate 7 and sealed to it. In this embodiment, the sealing plate 16 is made of rubber. Due to its excellent elasticity and shock absorption performance, the rubber sealing plate 16 can effectively reduce the impact of water flow on the sealing effect between the filter plate 7 and the mounting groove 2, thereby ensuring tight contact between the rubber sealing plate and the sealing gasket 3. This invention utilizes a corrugated rubber sleeve 17 and a compression spring 18 to press the rubber sealing plate 16 firmly onto the mounting groove 2, ensuring tight contact between the sealing plate 16 and the sealing gasket 3. Combined with the sealing sleeve 8, this improves the tightness of contact between the inner wall of the mounting groove 2 and the outer periphery of the filter plate 7, thereby improving the sealing performance and preventing leakage.

[0033] Specifically, such as Figure 2 As shown, slots 4 are provided at both ends of the top of the inner part of the mounting groove 2.

[0034] like Figures 3 to 5 As shown, the cover plate 9 is fixedly installed with the insert plate 11 facing the mounting groove 2, and the insert plate 11 corresponds to the slot 4 one by one. Each pair of corresponding insert plates 11 and slot 4 are inserted into each other, and the insert plate 11 and slot 4 are snapped together.

[0035] Furthermore, in this embodiment of the present invention, fixed clamping plates 12 are fixedly installed on both sides of the end of the insert plate 11 away from the cover plate 9. A sliding groove 13 is formed inside the insert plate 11, and a movable clamping plate 14 is slidably connected in the sliding groove 13. The two ends of the movable clamping plate 14 extend to the outside of the sliding groove 13. Both ends of the fixed clamping plate 12 and the movable clamping plate 14 are provided with inclined surfaces, and the inclined surfaces at both ends of the fixed clamping plate 12 are opposite to and reversed from the inclined surfaces at both ends of the movable clamping plate 14. A locking block 5 is slidably connected to the inner wall surface on both sides of the slot 4. The end of the locking block 5 away from the inner wall of the slot 4 is provided with an inclined surface, and the inclined surface faces the opening of the slot 4. The locking block 5, the fixed clamping plate 12 and the movable clamping plate 14 can cooperate with each other so that the insert plate 11 is locked in the slot 4.

[0036] Furthermore, a reset spring 15 is provided between the movable plate 14 and the top wall of the slide groove 13. The reset spring 15 is used for the movable plate 14 to slide telescopically relative to the fixed plate 12 within the slide groove 13. A snap-fit ​​spring 6 is provided at one end of the locking block 5 extending into the slot 4. The locking block 5 can slide telescopically within the slot 4 through the snap-fit ​​spring 6.

[0037] like Figures 1 to 4 As shown, the filter device also includes a handle 10, which is disposed opposite to the filter plate 7 and is fixedly installed on the top of the cover plate 9, so as to facilitate the operator to lift or press the filter device.

[0038] In the specific use of this utility model, the filter plate 7 is inserted into the interior of the mounting groove 2, and the insert plate 11 is inserted into the interior of the slot 4. When the insert plate 11 is inserted into the interior of the slot 4, the filter device is installed and fixed in the mounting groove 2 through the mutual cooperation between the locking block 5, the fixed locking plate 12 and the movable locking plate 14. During this process, the compression spring 18 is in a contracted state. The sealing gasket 3 and the sealing sleeve 8, together with the sealing plate 16, ensure the sealing between the inner wall of the mounting groove 2 and the filter plate 7. Simultaneously, when the filter device needs to be disassembled or assembled, the pump body is turned off, and the cover plate 9 is moved down by pressing down the handle 10, thereby causing the insert plate 11 to be inserted deep into the slot 4. The movable retaining plate 14 moves down until it moves below the retaining block 5 and merges with the fixed retaining plate 12. Then, the filter device is pulled up, causing the insert plate 11 to move upward towards the slot 4. At the same time, the movable retaining plate 14 moves downward relative to the fixed retaining plate 12 along the track of the slide groove 13, and gradually merges with the fixed retaining plate 12 until the two are completely merged. After the movable retaining plate 14 is fully merged, the inclined surface of the movable retaining plate 14 acts... As the insert plate 11 continues to rise, the movable locking plate 14 presses against the locking block 5, causing it to contract and compressing the locking spring 6 until the locking block 5 is completely retracted into the inner wall of the slot 4, thereby releasing the locking state and facilitating the removal of the filter device for quick disassembly. After cleaning or replacement of the new filter plate 7, the filter plate 7 is inserted into the mounting groove 2, causing the insert plate 11 to be inserted into the slot 4, and the fixing locking plate 12 is pressed under the locking block 5 to achieve the locking state, thereby achieving the installation and fixation of the filter device.

[0039] 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.
