Abstract

The blow-down valve with the dirt collecting function comprises a lower valve seat connected with a blow-down pipeline, an upper valve seat is fixedly installed on the outer side of the lower valve seat, a valve rod is installed in the upper valve seat, and a sealing plug is fixedly installed at the lower end of the valve rod; the movable ring is movably arranged on the inner side of the lower valve seat; the flow guide hole is formed between the lower valve seat and the collecting seat, and a containing groove is formed in the side wall of the flow guide hole; the drain outlet is formed in the lower surface of the left end of the collecting seat, and the inner side of the drain outlet is in shaft connection with a blocking plate; the shaft rod is in shaft connection with the inner side of the collecting seat, and an impeller is arranged on the outer side of the shaft rod. According to the blow-down valve with the dirt collecting function, large-particle impurities in sewage can be automatically filtered and blocked, abrasion of the valve assembly is effectively avoided, meanwhile, the filtered impurities can be automatically collected and discharged under the driving effect of water flow, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of blowdown valves, in particular to a blowdown valve with a dirt collection function. Background technique [0002] The blowdown valve is a valve evolved from a gate valve. It is widely used in boilers, water heaters and other water heating products. The blowdown valve can effectively discharge the sediment and sewage generated inside the boiler and other heating devices, but the existing There are still some deficiencies in the blowdown valve. [0003] For example, a sewage valve with publication number CN201910761111.7 is provided with intercepting plates on the inner wall of the valve cavity and adjacent to the ends, and the two ends of the intercepting plates are provided with fouling holes to intercept the scale and mud in the boiler through the intercepting plates. scum. Avoid larger particles of scale and sludge from the valve cavity into the sewage pipeline, so that the sewage pipeline is blocked,...
