Description

Technical Field

[0001] The utility model specifically relates to a hydraulic double-position single-hole stop valve for concrete pumping, belonging to the technical field of stop valves. Background Art

[0002] The hydraulic double-position single-hole stop valve for concrete pumping is a controller specially used in concrete delivery pipelines. It realizes double positions through hydraulic means, that is, two states: open and closed, and has only one inlet and outlet. In principle, the stop valve controls the opening and closing of the valve through the operation of the hydraulic system, thereby controlling the flow of concrete. When the valve is closed, concrete cannot pass through; when the valve is open, concrete can flow smoothly.

[0003] The existing hydraulic double-position single-hole stop valve has a compact structure and strong practicality, but the hydraulic telescopic rod on the existing hydraulic double-position single-hole stop valve is generally connected by multiple bolts, which makes installation inconvenient. In addition, when the hydraulic double-position single-hole stop valve is in use, the delivery pipe on the hydraulic double-position single-hole stop valve needs to be connected to the external pipe through a flange. Since the flange on the delivery pipe cannot rotate, when the connecting hole of the flange is misaligned with the flange connecting hole on the external pipe, it is inconvenient to connect the two flanges.

[0004] In view of this, a hydraulic double-position single-hole stop valve for concrete pumping is proposed. Utility Model Content
