Detailed Implementation
[0014] 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.
[0015] Please see Figures 1-5 This utility model provides a technical solution: a pulse valve flushing device for a tap water tank, comprising a pure water tank 1, a tap water tank 7, a storage tank 6, and a detachable valve fixture 5. The pure water tank 1 and the storage tank 6 are respectively used to provide initial flushing water and deep cleaning water. A water pump 2 and a pulse control valve 3 are fixedly connected between the outlets of the pure water tank 1 and the tap water tank 7 via pipes. A filter device 8 is fixedly connected between the inlets of the tap water tank 7 and the storage tank 6 via pipes. A connecting pipe 10 is fixedly connected to the outlet pipe end of the tap water tank 7, and the left side surface of the connecting pipe 10 slides. A water pipe 11 is connected, and a rotating retaining ring 9 is rotatably connected to the annular surface of the water pipe 11. A retaining block 15 is fixedly connected to the inner wall of the rotating retaining ring 9. A rotating nozzle 14 is fixedly connected to the left end of the water pipe 11. A round rod 12 is fixedly welded to the right side plane of the detachable valve fixture 5. The surface of the round rod 12 is slidably connected to the round hole on the left side of the connecting flange 13. The protruding structure of the retaining block 15 is rotatably connected to the groove structure of the round rod 12. This design solves the problem that the original device is difficult to completely remove impurities and surface contaminants attached to the valve cavity, which affects the accuracy and repeatability of subsequent test results.
[0016] As the first embodiment of this utility model: a sealing ring 16 is fixedly connected in the annular groove on the left side of the connecting flange 13. The left side of the sealing ring 16 is in close contact with the right end of the detachable valve fixture 5. The sealing ring 16 provided on the mating surface of the connecting flange 13 and the detachable valve fixture 5 is pressed and sealed in the clamping state, which effectively prevents leakage of high pressure pulse water flow and ensures that the flushing pressure is fully applied to the inside of the fixture.
[0017] A filter cylinder 17 is fixedly connected to the surface of the water pump 2's pumping pipe. A filter element is installed inside the filter cylinder 17. The water pump 2 provides stable water pressure. Its inlet end is connected to the filter cylinder 17, which contains a replaceable filter element to prevent impurities in the pipe from entering the pump body and causing wear.
[0018] The nozzle of the rotating nozzle 14 is made of stainless steel and achieves 360° rotating spray under the drive of pulsed water flow, covering the inner cavity, sealing surface and flow channel of the detachable valve fixture 5. The rotating nozzle 14 is made of stainless steel and has an eccentric water channel or turbine structure inside. It rotates automatically under the impact of pulsed water flow to achieve full circumference, multi-angle and no dead angle spray. The coverage area includes the inner cavity of the detachable valve fixture 5, valve seat sealing surface, flow channel corners and other areas that are difficult to reach by traditional flushing.
[0019] The filtration device 8 includes a primary filter element, an activated carbon filter element, and a precision filter membrane connected in sequence. The flushed wastewater flows into the water storage tank 6 for temporary storage. The water storage tank 6 is returned to the tap water tank 7 through the filtration device 8 via a pipeline. This filtration device adopts a three-stage filtration structure. The primary filter element can intercept large particles of silt and rust, the activated carbon filter element can adsorb organic matter, residual chlorine and odors, and the precision filter membrane can remove micron-sized suspended solids and some microorganisms.
[0020] The pure water tank 1 and the tap water tank 7 are arranged in parallel. Their respective outlet pipes are connected to the connecting pipe of the detachable valve fixture 5 after being merged. The tap water tank 7 provides regular rinsing water, which is suitable for the preliminary rinsing stage and can effectively remove large particulate impurities and surface dust in the detachable valve fixture 5. The pure water tank 1 stores deionized water or ultrapure water for deep final rinsing of valve samples to avoid interference from trace ions in tap water with subsequent test results.
[0021] As the second embodiment of this utility model: First, the cleaning valve is installed in the detachable valve fixture 5. This fixture can be quickly replaced according to the valve diameter. Align the front end of the water pipe 11 with the fixture interface, push it in, and rotate the rotating retaining ring 9 so that the retaining block 15 is embedded in the groove of the round rod 12 to complete the mechanical locking and sealing. Turn on the water pump 2 and the pulse control valve 3, switch the water source to the tap water tank 7, and perform pulse cleaning to remove surface contaminants. The rotating nozzle 14 sprays through 360° rotation to improve the cleaning coverage and impact force of complex internal structures. Turn off the tap water circuit, switch to the pure water tank 1, and start the pulse again to thoroughly remove residual ions and particles. The rinsing wastewater is discharged into the water storage tank 6, purified by the filter device 8, and returned to the tap water tank 7 for later use. Rotate the retaining ring in the opposite direction to loosen the retaining block 15 from the groove of the round rod 12, and then remove the detachable valve fixture 5 after cleaning.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
