[0041] Example: Reference Figure 1-5 An electric pressure proportional regulating valve shown in the figure comprises a valve body 1 and a control part 5 for regulating the internal pressure of the valve body, the top of the valve body 1 is respectively fixedly connected with an intermediate valve body 3 and a connecting seat 4, the connecting seat 4 is connected with the control part 5, and a clamping structure is movably provided on the control part 5;

[0042] The valve body 1 is clamped with the control part 5 through a clamping structure;

[0043] The top of the control part 5 is also provided with an adjustment structure for adjusting the position of the clamping structure;

[0044] The adjusting structure can drive the clamping structure to change position, so that the valve body 1 and the control part 5 are loosened or tightly fitted.

[0045] The valve body 1 is connected to the control part 5 through the connecting seat 4, and then they are clamped together and fixed through a clamping structure. Then the position of the clamping structure is controlled by the adjusting structure to make the valve body and the control part 5 tightly connected, so that the data is connected, thereby controlling the valve body 1 through the control part 5.

[0046] The provided clip-on structure can better connect the valve body 1 and the control part 5, ensuring the tightness of the connection. Compared with the traditional clip-on fit, it avoids the problem of loose fit caused by wear of the clip-on parts or other external reasons during long-term use, making it more stable during use.

[0047] like Figure 2-3 As shown, the connecting seat 4 is fixedly connected to the middle valve body 3;

[0048] The connecting seat 4 and the control unit 5 are connected to each other through the docking seat 8 and the docking slot 10;

[0049] The docking seat 8 and the docking slot 10 are docked for data transmission.

[0050] In summary, after the docking seat 8 and the docking groove 10 are docked, the two data transmission channels will be connected, so that the valve body 1 at the bottom is controlled by the control unit 5. The specific control method is electric control, which is a prior art and will not be repeated.

[0051] like Figure 4-5 As shown, the clamping structure includes a threaded sleeve 15 arranged on the top of the control part 5, and bent plates 16 are fixedly connected to both sides of the threaded sleeve 15. One end of the bent plate 16 is fixedly connected to two inclined plates 19 inclined to both sides, and a clamping block 20 is fixedly connected to the inclined plate 19. The adjustment structure cooperates with the threaded sleeve 15;

[0052] The connecting seat 4 is provided with a card slot 9, and the card block 20 matches with the card slot 9;

[0053] A connecting plate is fixedly connected between the two inclined plates 19;

[0054] Both sides of the control part 5 are fixedly connected with a guide frame 13 for guiding the bending plate 16, and the bending plate 16 partially slides in the guide frame 13;

[0055] A reinforcing plate 17 is fixedly connected to the connection between the bending plate 16 and the inclined plate 19;

[0056] The design of the reinforcing plate 17 enhances the connection strength between the inclined plate 19 and the bending plate 16 to prevent them from being easily deformed, while the design of the connecting plate enhances the connection strength between the two inclined plates 19, tightly connecting the two inclined plates 19 together to prevent the inclined plates 19 from being deformed, and the guide frame 13 limits the sliding direction of the bending plate 16 to prevent the bending plate 16 from rotating synchronously when the threaded sleeve 15 rotates.

[0057] Wedge blocks 14 are fixedly connected to both sides of the control part 5, and a guide groove 18 is opened at the reinforcing plate 17, and the wedge blocks 14 are located in the guide groove 18;

[0058] One of the corner edges of the guide groove 18 is provided with a chamfered groove that cooperates with the wedge block 14 .

[0059] In summary, when the adjusting structure drives the bending plate 16 to slide downward, the guide groove 18 at the reinforcing plate 17 will also approach the wedge block 14, and as the bending plate 16 continues to move downward, the wedge groove at the guide groove 18 will contact the wedge block 14, and then the bending plate 16 will be tilted up through the resistance of the wedge block 14, thereby separating the block 20 and the slot 9, thereby separating the valve body 1 at the bottom from the control part 5; when the adjusting structure drives the bending plate 16 to slide upward, the block 20 located in the slot 9 will be pulled upward, thereby tightly fitting the connecting seat 4 and the control part 5.

[0060] The design of the wedge block 14 and the guide groove 18 has an auxiliary guiding function for the bending plate 16. With the adaptation of the wedge block 14 and the guide groove 18, the block 20 can be separated from the slot 9 by controlling the bending plate 16 to slide downward, and the overall disassembly is simple and convenient. While the block 20 and the slot 9 are engaged and connected, the block 20 can pull the top wall of the slot 9 by adjusting the bending plate 16 upward, so that the control part 5 and the connecting seat 4 can be more tightly connected. Even if the block 20 and the slot 9 are worn during multiple disassembly and assembly or use, the fitting precision can be guaranteed by adjusting the position of the bending plate 16, and the disassembly is simple and convenient.

[0061] like Figure 4 As shown, the adjustment structure includes a threaded column 11 rotatably connected to the top of the control part 5, a knob 12 is fixedly connected to the top of the threaded column 11, and a threaded sleeve 15 is threadedly sleeved on the threaded column 11;

[0062] The knob 12 includes a rotating block and two ear plates fixedly connected to the rotating block.

[0063] Rotating the knob 12 can drive the threaded column 11 to rotate in the positive direction, thereby driving the threaded sleeve 15 to slide up and down along the threaded column 11, so as to adjust the position of the threaded sleeve 15.

[0064] The design of the two ear plates facilitates hand operation. The threaded column 11 can be rotated by pinching the two ear plates with fingers. Compared with the traditional circular turntable, the operation is simpler and the overall structure is simple. The threaded sleeve 15 can be controlled to slide by rotating forward and reverse, and the cost is low.

[0065] like Figure 2 As shown, the bottom of the valve body 1 is fixedly connected with a base 2 for fixing the valve body 1;

[0066] The base 2 is connected to external supporting components through bolts.

[0067] The base 2 is used to install the valve body 1 on an external support part, and then fix it through bolt thread connection.

[0068] By setting the base 2, the valve body 1 can be installed on an external support part, which can effectively support the valve body 1 and prevent the valve body 1 from being suspended in the air and causing the valve body 1 to fall, thereby facilitating the installation and docking of the valve body 1 and the pipeline and increasing the service life of the valve body 1.

[0069] like Figure 3 As shown, buttons 6 and display screen 7 are respectively provided on the side walls of the control unit 5;

[0070] The display screen 7 is used to display the value recognized by the control unit 5:

[0071] The button 6 can be used to manually control the control unit 5 .

[0072] The control unit 5 , button 6 and display screen 7 are all prior art, and the specific working principles will not be elaborated. The control unit 5 can be manually controlled by operating the button 6 , and the specific values ​​will be displayed on the display screen 7 .

[0073] In summary, by setting the button 6 on the side wall of the control part 5, compared with the traditional button 6 installed on the top of the control part 5, the space on the top of the control part 5 is freed up, and the adjustment and use of the top clip structure will not be affected.

[0074] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
