Description

Technical Field

[0001] The present application relates to the technical field of stop valves, and in particular to a stop valve for a concrete pouring pump pipe. Background Art

[0002] In recent years, high-rise and super-high-rise buildings have become a mainstream form of construction in my country. Due to the high floor heights and heavy loads associated with these structures, the concrete strength grades of their walls and columns are relatively high, significantly different from the concrete grades of their beams and slabs. When these different grades of concrete are poured integrally, they can easily cause a mixture of high- and low-grade concrete. Furthermore, concrete can easily leak from the concrete placing boom during pumping, contaminating the external safety netting.

[0003] The existing stop valve is not convenient for scraping and cleaning the materials remaining in the valve body channel during actual use, which requires staff to disassemble the valve body when not in use, and then manually disassemble, clean and maintain it, which is time-consuming, labor-intensive and inefficient.
