The invention discloses an anti-blocking device and method for a regulating valve capable of conveying liquid-solid phase fluids intermittently and belongs to the technical field of automatic meter measurement. The device comprises a vertically arranged conveying main pipe, the regulating valve is arranged on the conveying main pipe, a back washing water inlet pipe is arranged on the conveying main pipe on the lower side of the regulating valve, a back washing water outlet pipe is arranged on the conveying main pipe on the upper side of the regulating valve, and stop valves are arranged on theback washing water inlet pipe and the back washing water outlet pipe; and stop valves are arranged on the conveying main pipe on the lower side of the backwashing water inlet pipe and the conveying main pipe on the upper side of the backwashing water outlet pipe. Anti-blocking treatment of the regulating valve is carried out by a method of flushing the regulating valve. The device solves the problems of stagnation of the regulating valve, severe wear of the valve element, blockage of a runner in the regulating valve and the like due to scaling of the valve element and a valve seat of the regulating valve, achieves effects of high precision regulation and long-term use of the regulating valve and is convenient to popularize and use.
Description
Technical field[0001]The invention relates to the technical field of automatic instrument measurement, in particular to a regulating valve anti-blocking device and method for intermittently conveying liquid-solid two-phase fluids, and is suitable for pH adjustment tanks of industrial wastewater treatment stations where solid-liquid two-phase fluids cannot achieve a suspended flow state The precise and stable adjustment of the feed ensures the stability of the pH value of the final discharge of wastewater and the standardized discharge of industrial wastewater.Background technique[0002]The degree of compliance with wastewater discharge standards in industrial, mining and metallurgical enterprises has always been a matter of close concern. Among them, the adjustment accuracy of instrumentation equipment will directly affect the quality of wastewater treatment. In addition to the final detection of water quality analysis instruments (PH meter, turbidity meter, etc.), to ensure that the...
