[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] A specific embodiment of this utility model provides a valve filter, combined with the attached... Figure 1 With appendix Figure 2 As shown, it includes a shut-off valve and a basket filter screen installed inside the shut-off valve. The shut-off valve 1 is externally equipped with a pressure detection mechanism 2, a control module 3 and a control mechanism 4. The pressure detection mechanism 2 includes a pressure gauge 21, a differential pressure detector 22 and a connecting pipe 23. The two ends of the connecting pipe 23 are connected to the shut-off valve 1, and the two ends of the connecting pipe 23 are located on both sides of the basket filter screen inlet and outlet position.

[0027] Pressure gauge 21 and differential pressure detector 22 are installed on connecting pipe 23, and differential pressure detector 22 is electrically connected to control module 3;

[0028] The control mechanism 4 is located at the bottom sludge removal port of the stop valve 1 and is connected to the bottom sludge removal port of the stop valve 1.

[0029] Specifically, both ends of the connecting pipe 23 are equipped with tee connectors 24. The tee connectors 24 are used to connect the shut-off valve 1, the pressure gauge 21 and the differential pressure detector 22. The pressure gauge 21 is equipped with a first pressure gauge and a second pressure gauge. The first pressure gauge is connected to one of the tee connectors 24 and the second pressure gauge is connected to the other tee connector 24. The first pressure gauge and the second pressure gauge are used to record the water pressure values ​​on both sides of the basket filter screen inside the shut-off valve. The two water pressure values ​​are aggregated to the control module 3 through the differential pressure detector 22.

[0030] Specifically, the control module 3 includes a numerical analysis module, a judgment module, and an execution module. The numerical analysis module receives the water pressure value from the differential pressure detector 22, analyzes it, and inputs the analysis result to the judgment module. The judgment module determines whether to open the sludge removal port to discharge impurities in the shut-off valve 1 based on the difference range of the values, and inputs the judgment result to the execution module. The execution module controls the control mechanism 4 to open and close the sludge removal port.

[0031] Specifically, the control mechanism 4 includes a rotary motor 41, a control arm 42, and a sealing cover 43. The rotary motor 41 is fixed to the side of the sludge removal port of the shut-off valve 1 by bolts. The output end of the rotary motor 41 is provided with a control arm 42, which is an L-shaped arm. The other end of the control arm 42 is provided with a sealing cover 43. The control arm 42 drives the sealing cover 43 to move as the rotary motor 41 rotates. The control arm 42 drives the sealing cover 43 to rotate in a circular motion. The sludge removal port and the sealing cover 43 are perpendicularly connected.

[0032] Specifically, a rubber sealing ring 44 is provided on the outer ring of the sealing cover 43. The sealing of the shut-off valve 1 can be greatly enhanced by the rubber sealing ring 44 working in conjunction with the sealing cover 43.

[0033] The working principle of this embodiment:

[0034] The shut-off valve 1 includes an inlet, an outlet, and a sludge removal port. The inlet and outlet are arranged opposite to each other. A basket filter screen is installed inside the shut-off valve 1 between the inlet and outlet, and impurities can accumulate at the sludge removal port.

[0035] The two ends of the connecting pipe 23 are respectively set at the inlet and outlet. A first pressure gauge and a second pressure gauge are also set at both ends of the connecting pipe 23. A differential pressure detector 22 is set in the middle of the connecting pipe 23. The differential pressure detector can collect the inlet water pressure value and outlet water pressure value detected by the first pressure gauge and the second pressure gauge. The differential pressure detector is electrically connected to the control module 3. The inlet water pressure value and the outlet water pressure value are input to the numerical analysis module of the control module 3. The numerical analysis module has a preset difference range. If the difference value is higher than the difference range, it means that there are a lot of impurities in the basket filter screen and it needs to be cleaned. The analysis result is input to the judgment module. When the judgment module determines that it needs to be cleaned, the judgment result is input to the execution module.

[0036] The rotating motor 41 is electrically connected to the execution module. The execution module outputs an opening command, and the rotating motor 41 rotates to drive the control arm 42 to open the sealing cover 43, thereby achieving sludge removal. After sludge removal, if the water pressure values ​​at the inlet and outlet are less than the preset difference range of the numerical analysis module, the judgment module will judge and the execution module will control the rotating motor 41 to drive the control arm 42 to close the sealing cover 43, thus achieving automatic sludge removal.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
