Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings and valves, in particular to a flow regulating valve with filtering effect. Background Art

[0002] The flow regulating valve is also known as the self-operated flow control valve, flow balancing valve, and static balancing valve. It is an intuitive and simple flow regulating control device. The flow regulating valve used in the pipeline network can directly set the flow according to the design. The valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline under the action of water. No matter how the system pressure changes, the set flow rate is maintained unchanged. These functions of the valve enable the pipeline network flow regulation to be completed at one time, turning the network adjustment work into a simple flow distribution, and effectively solving the hydraulic imbalance of the pipeline network.

[0003] Since there are more or less trace amounts of metal impurities in general water flow, or the pipes are rusted after long-term use, causing rust to be integrated into the water flow, polluting the water flow, affecting subsequent use, and even causing users to drink contaminated water, which directly affects human health. Existing pipes or valves lack the function of filtering metal impurities. In order to use cleaner water sources, it is necessary to install a water purifier before the water outlet terminal. However, the cost of water purifiers is often high, and low-end ones also cost nearly a thousand yuan. The cost of subsequent maintenance and replacement is also high, and the operation is also very troublesome. Many families cannot afford it. Therefore, a flow control valve with a filtering effect is proposed.

[0004] A regulating valve with a filtering function is disclosed in the announcement number CN212407690U. Although the regulating valve with a filtering function relates to the field of regulating valves, the regulating valve used is difficult to clean and is not conducive to later use. The following scheme is proposed, which includes a valve body, a flow groove is provided inside the valve body, a valve ball is provided at the center of the flow groove, a valve stem is fixedly installed at the center of the valve ball in the vertical direction, a connecting disk is symmetrically distributed at one end of the valve body, a central rotating shaft is rotatably installed at the middle position of the two connecting disks, a mounting base, a cross connecting frame and a brush rod are fixedly installed on the central rotating shaft in sequence, blades are evenly distributed and fixedly installed on the circumferential outer wall of the mounting base, and a scraping strip is fixedly installed on the cross connecting frame. The utility model has a novel structure, a better filtering effect, is easy to clean and replace in the later stage, and also has the function of preventing backflow, and is highly practical.

[0005] Although the above patent has a novel structure and better filtering effect, is easy to clean and replace later, and has the function of preventing backflow, it is highly practical; however, the device lacks the function of collecting and processing the cleaned impurities to prevent impurities from entering the valve or pipeline, thereby reducing the risk of valve and pipeline blockage.

[0006] Therefore, it is necessary to invent a flow control valve with filtering effect to solve the above problems. Utility Model Content

[0017] (III) Beneficial effects

[0018] The utility model provides a flow regulating valve with filtering effect, which has the following beneficial effects:

[0019] 1. The flow regulating valve with filtering effect is set through the cleaning mechanism, filter screen and collection mechanism, solenoid valve A and solenoid valve B. When in use, the integrated control panel is controlled to open the solenoid valve A, and the solenoid valve B and the diverter valve are closed. At this time, there is no water source passing through the filter tube, and the hydraulic rod inside the filter tube is started. The hydraulic rod is extended and retracted to drive the brush at the bottom to reciprocate on the surface of the filter screen, and the impurities attached to the surface of the filter screen are brushed off to the collection bin just below. After cleaning, the solenoid valve A is closed, and the solenoid valve B and the diverter valve are opened.
