[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 5 As shown, this utility model provides a water pump control valve with protective function, including a water pump control valve body 1, a mounting base 2 fixedly connected to the upper surface of the outer surface of the water pump control valve body 1, a protective shell 3 overlapping the upper surface of the mounting base 2, and four loading and unloading components 4 arranged in the middle of the front and rear sides, left and right sides between the mounting base 2 and the protective shell 3.

[0027] By providing a protective shell 3, the valve body rotary handle 5 can be effectively protected, preventing accidental contact that could cause it to rotate. Simultaneously, the design of the mounting and dismounting assembly 4 facilitates the installation and removal of the protective shell 3. When using the water pump control valve body 1, rotating the valve body rotary handle 5 moves the valve core inside the water pump control valve body 1, thereby achieving the closing or opening operation.

[0028] like Figures 1 to 5 As shown, a valve body rotating handle 5 is movably connected inside the water pump control valve body 1 and the mounting base 2. A sealing rubber 21 is fixedly connected to the upper surface of the mounting base 2, and the outer surface of the sealing rubber 21 overlaps with the inner wall of the protective shell 3. Each of the four loading and unloading components 4 includes a plate 41 and a rotating shaft 49. The left and right sides of the plate 41 are provided with through grooves 42 that communicate with each other. The front of the plate 41 is provided with a sliding groove 43 that communicates with each other. A spring 44 is fixedly connected to the upper surface of the inner wall of the plate 41. A T-shaped block 45 is fixedly connected to the lower end of the spring 44. The outer surface of the T-shaped block 45 overlaps with the inner surface of the through groove 42 and the sliding groove 43. The sliding connection is provided. A connecting block 48 is fixedly connected to the front side of the outer surface of the rotating shaft 49. A fixing ring 47 is fixedly connected to the end of the connecting block 48 away from the rotating shaft 49. The outer surface of the rotating shaft 49 passes through the interior of the mounting base 2 and is movably connected. The surface of the plate 41 is fixedly connected to the surface of the protective shell 3. An opening is provided on the lower inner side of the fixing ring 47. A groove is provided on the front side of the protruding part of the T-shaped block 45. A limiting plate 46 is movably connected inside the groove. An insertion port is provided on the lower left side of the limiting plate 46. The insertion port in the limiting plate 46 is inserted into the outer surface of the fixing ring 47. The spring 44 is in a stretched state.

[0029] In use, first place the protective shell 3 on the upper surface of the mounting base 2, ensuring it is in close contact with the sealing rubber 21 to achieve a sealing effect. Next, the operator moves the T-block 45 downwards, stretching the spring 44. Then, adjust the flip-up limiting plate 46 to the appropriate position and rotate the fixing ring 47 so that its opening faces upwards. When the fixing ring 47 is rotated again, its outer surface will embed into the slot of the limiting plate 46. Stop operation when the opening of the fixing ring 47 faces downwards. Due to the elasticity of the stretched spring 44, the fixing ring 47 is tightened and limited, completing the assembly and locking process. Conversely, if disassembly is required, rotate the fixing ring 47 so that its opening faces upwards. Under the action of the stretched spring 44, the limiting plate 46 will be pulled and moved, completing the disassembly operation. At this time, moving the protective shell 3 upwards exposes the valve body rotating handle 5, facilitating its opening and closing.

[0030] like Figures 1 to 5As shown, vertical grooves 31 are provided on both the left and right sides of the inner wall of the protective shell 3. The lower surface of the inner wall of the vertical groove 31 is connected to the inside and outside. The protective shell 3 is made of metal. A magnetic block 32 is slidably connected inside the vertical groove 31, and the outer surface of the magnetic block 32 is magnetically fixed to the inner wall of the vertical groove 31. A fixing plate 33 is fixedly connected to the opposite face of the left and right magnetic blocks 32. A drying plate 34 is provided on the opposite face of the left and right fixing plates 33. A rectangular array of opposite faces of the left and right drying plates 34 is provided with four positioning holes 341 that are connected to the left and right. A rectangular array of opposite faces of the left and right fixing plates 33 is fixedly connected with four inserts 331 and rubber blocks 332. The outer surface of the four inserts 331 is inserted into the inside of the positioning holes 341 respectively. A conical surface is provided on both the left and right sides of the outer surface of the rubber block 332.

[0031] When the protective shell 3 protects the valve body rotary handle 5, the drying plate 34 absorbs the humid air inside the protective shell 3, keeping the inner cavity dry and preventing moisture in the humid air from contacting the valve body rotary handle 5. When it is necessary to replace the drying plate 34 after prolonged use, the following steps can be taken: First, remove the protective shell 3; then, move the drying plate 34 downwards, allowing the magnetic block 32 to slide downwards inside the vertical groove 31 and separate from the protective shell 3; next, manually move the drying plate 34, squeezing and compressing the rubber block 332 during the movement to complete the disassembly and replacement operation. The rubber block 332 is designed to block the drying plate 34, ensuring its stability after installation. The conical surface of the rubber block 332 facilitates better compression of the rubber block 332.

[0032] The working principle of this protective water pump control valve will be explained in detail below.

[0033] In use, first place the protective shell 3 on the upper surface of the mounting base 2, ensuring it is in close contact with the sealing rubber 21. Next, the operator moves the T-shaped block 45 downwards, stretching the spring 44. Then, adjust the flip-up limiting plate 46 to the appropriate position and rotate the fixing ring 47 so that the opening faces upwards. Rotating the fixing ring 47 again will cause its outer surface to embed into the slot of the limiting plate 46, thus completing the assembly and locking process. When the protective shell 3 protects the valve body rotating handle 5, the drying plate 34 absorbs humid air from the interior of the protective shell 3, keeping the inner cavity dry and preventing moisture from the air from contacting the valve body rotating handle 5. When the drying plate 34 needs to be replaced after prolonged use, move the drying plate 34 downwards, causing the magnetic block 32 to slide downwards inside the vertical groove 31 and separate from the protective shell 3. Then, manually move the drying plate 34 and squeeze the rubber block 332 to shrink it, completing the disassembly and replacement operation.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
