In a project, flow meters of various sizes may be used, resulting in various installation methods, cumbersome use process and high cost. However, the above existing technology cannot soften the fluid in the pipe. Hard water will cause scale to accumulate on the inner wall of the pipe and block the water pipe, which is not conducive to the circulation of the liquid in the pipe.

[0004] In order to solve the above problems, the utility model provides a flow meter. Utility Model Content

[0023] Example

[0024] refer to Figure 1-5 A flowmeter comprises a filter box 2 and a flowmeter body 13. A liquid inlet is provided at the upper end of the filter box 2, and a liquid inlet pipe 1 is fixedly connected to the liquid inlet. A liquid discharge port 10 is provided at the lower end of the filter box 2, and a No. 1 pipe 11 is fixedly connected to the liquid discharge port 10. A No. 1 flange 12 is fixedly installed on the lower end side wall of the No. 1 pipe 11, and the No. 1 flange 12 is fixedly connected to the flowmeter body 13 through fixing bolts. A mounting groove 3 is provided in the filter box 2, and a rotating rod groove 4 is symmetrically provided on the side wall of the filter box 2. A rotating rod 5 is provided in the two rotating rod grooves 4, and two bent buckles 6 are fixedly sleeved on the rotating rod 5. A filter plate 7 is provided in the mounting groove 3, and four magnetic buckle columns 8 matching the bent buckles 6 are fixedly installed on the side wall of the filter plate 7. An ion exchange resin net is fixedly installed in the filter plate 7. The end of the flowmeter body 13 away from the No. 1 flange 12 is fixedly connected to a No. 2 flange 14 through the same fixing bolts, and the No. 2 flange 14 is fixedly connected to the No. 2 pipe 15.

[0025] First, the No. 1 flange 12 is fixedly connected to the No. 1 pipe 11, and the No. 2 flange 14 is fixedly connected to the No. 2 pipe 15. Then, the No. 1 flange 12 and the No. 2 flange 14 are fixedly connected to the two ends of the flow meter body 13 through fixing bolts. First, the two rotating rods 5 in the rotating rod slot 4 are rotated in opposite directions, and then the filter plate 7 is inserted into the filter box 2 through the mounting slot 3. When the four magnetic buckle columns 8 on the side wall of the filter plate 7 match the positions of the four curved buckles 6 on the two rotating rods 5, the two rotating rods 5 are rotated toward each other so that the four curved buckles 6 are all buckled into the magnetic buckle columns 8. At this time, the rotation is completed. The movable rod 5 and the bent buckle 6 are used to fix the filter plate 7 in the filter box 2. When the tap water enters the filter box 2 through the liquid inlet pipe 1, the tap water will contact the ion exchange resin net on the filter plate 7. The ion exchange resin net can soften the tap water. The softened tap water flows to the No. 1 pipe 11 through the filter plate 7 and the drain port 10 and enters the No. 1 pipe 11. Then, the softened tap water passes through the No. 1 flange 12 and enters the flow meter body 13. The flow meter body 13 calculates the flow of the softened tap water, and then continues to flow downward through the No. 2 flange 14 and the No. 2 pipe 15.

[0026] A knob block 9 is fixedly mounted on one end of the rotating rod 5 , and an anti-slip pattern is provided on the side wall of the knob block 9 .

[0027] By setting the knob block 9, the staff can better rotate the two rotating rods 5;

[0028] The end of the rotating rod 5 facing away from the knob block 9 is rotatably connected to the inner wall of the rotating rod groove 4 .

[0029] By making one end of the rotating rod 5 rotatably connected to the inner wall of the rotating rod groove 4, the rotating rod 5 can be rotated in the rotating rod groove 4;

[0030] The four curved buckles 6 are all slidably connected to the matching magnetic buckle columns 8 .

[0031] By making the four curved buckles 6 slidably connected with the matching magnetic buckle columns 8, the four curved buckles 6 can be buckled in the magnetic buckle columns 8, and the magnetic buckle columns 8 can also magnetically fix the matching curved buckles 6, so that the curved buckles 6 and the magnetic buckle columns 8 are more stable and firm;

[0032] The filter plate 7 is slidably connected to the inner wall of the mounting groove 3 .

[0033] By making the filter plate 7 slidably connected with the mounting groove 3, the filter plate 7 can slide and move in the mounting groove 3;

[0034] The two rotating rod grooves 4 are both connected to the mounting groove 3 .

[0035] By making the two rotating rod grooves 4 communicate with the installation groove 3, the curved buckles 6 on the two rotating rods 5 can limit and fix the magnetic buckle column 8.

[0036] The working principle of the utility model is as follows: first, the two rotating rods 5 in the rotating rod slot 4 are rotated in opposite directions by using the knob block 9, and then the filter plate 7 is inserted into the filter box 2 through the installation slot 3. When the four magnetic buckle columns 8 on the side wall of the filter plate 7 match the positions of the four curved buckles 6 on the two rotating rods 5, the two rotating rods 5 are rotated in opposite directions by using the knob block 9, so that the four curved buckles 6 are all buckled into the magnetic buckle columns 8. At this time, the rotating rod 5 and the curved buckle 6 are fixedly installed in the filter box 2 to prevent the filter plate 7 from being displaced by the pressure of the water flow when the tap water passes through the filter box 2, thereby reducing the softening effect of the water quality.

[0037] When tap water enters the filter box 2 through the liquid inlet pipe 1, the tap water will contact the ion exchange resin net on the filter plate 7, and the ion exchange resin net can soften the tap water. At this time, the softening treatment of the tap water is completed, avoiding the scale generated by the hard tap water from clogging the water pipe, and ensuring the smooth flow of the liquid in the pipe;

[0038] The softened tap water flows to the No. 1 pipe 11 through the filter plate 7 and the drain port 10. The softened tap water enters the No. 1 pipe 11 and enters the flow meter body 13 through the No. 1 flange 12. The flow meter body 13 calculates the flow of the softened tap water and then continues to flow downward through the No. 2 flange 14 and the No. 2 pipe 15.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and utility model concept of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
