[0002] A pipeline valve is a device used to control and regulate the flow of liquids or gases in a pipeline system, usually composed of a valve body, a valve cover, a valve seat, a seal, a driving device, etc. Pipeline valves are widely used in industrial, civil construction, water supply, drainage, gas and other fields. It is used to regulate the flow rate of the medium to ensure the normal operation of the pipeline conveying system. By controlling the opening degree of the valve or using a combination of multiple valves, intermittent or continuous conveying of the medium can be achieved.

These accumulated slag will reduce the diameter of the valve, resulting in a decrease in flow rate or a complete interruption. On the other hand, the accumulated slag may also change the flow field characteristics inside the valve, resulting in insensitive or inaccurate operation of the valve. Content of the Utility Model

[0020] Embodiment

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: an anti-blocking pipeline valve for preventing slag accumulation, including a valve 1, extension pipes 2 are arranged at both ends of the valve 1, and a cleaning assembly for cleaning impurities in the valve 1 is arranged outside the extension pipes 2. The cleaning assembly includes a mounting frame 3 arranged outside the extension pipes 2, which can be sleeved outside the extension pipes 2. A chute 301 is arranged on the outer wall of the mounting frame 3, and the chutes 301 are annularly distributed in the mounting frame 3 to position the angle when the slider 4 slides, so that the slider 4 slides annularly in the mounting frame 3. A slider 4 is arranged inside the chute 301, and an electromagnet 401 is arranged at one end of the slider 4. After the electromagnet 401 is energized, it can generate magnetic poles and magnetically adsorb with the magnetic plate 602 at one end of the support frame 6. Thus, the support frame 6 and the slider 4 move synchronously through the adsorption of the electromagnet 401 and the magnetic plate 602. An annular groove 5 is arranged on the inner wall of the extension pipe 2, and the annular grooves 5 are distributed on the inner wall of the extension pipe 2 and the angles correspond to those of the mounting frame 3. A support frame 6 is arranged inside the annular groove 5. The support frame 6 is used to connect with the scraper 601 and the magnetic plate 602, and the support frame 6 can rotate in the annular groove 5. (Through the annular sliding of the slider 4 in the mounting frame 3 and the magnetic attraction of the electromagnet 401 and the magnetic plate 602, the support frame 6 is driven to rotate annularly in the annular groove 5 synchronously). A scraper 601 is arranged at one end of the support frame 6. When the support frame 6 moves annularly, the scraper 601 can scrape on the inner wall of the extension pipe 2, so as to scrape and clean the impurities on the inner wall of the extension pipe 2. (And in the normal state, when the scraper 601 rotates in the extension pipe 2, it can stir the passing materials to prevent impurities from blocking in the valve 1 and avoid impurities sticking to the inner wall of the valve 1 to cause slag accumulation). A magnetic plate 602 is arranged at the other end. A impurity discharge pipe 7 is arranged at the bottom of the valve 1, and the impurity discharge pipe 7 can discharge the cleaned impurities (when cleaning and discharging impurities, the two ends of the valve 1 are closed to prevent materials from entering the impurity discharge pipe 7). A solenoid valve 701 is arranged at one end of the impurity discharge pipe 7 close to the valve 1, and the solenoid valve 701 is used to control the opening and closing of the impurity discharge pipe 7.

[0022] In this embodiment, all electrical components are controlled by a conventional controller.
