Problems solved by technology

The diameter of the rubber sleeve is limited, and the deformation of the rubber sleeve is large. When the deformation is large, the end of the rubber sleeve slips out between the flange and the end of the outer shell, and the seal of the pressure chamber is not good.
However, the opening of the discharge or water outlet is often relatively large. At this time, the flexible interception device cannot be applied, and can only be replaced by a structure such as a weir gate or a gate. Convenience, therefore, there is an urgent need for a flexible shut-off device that can be applied to large pipe diameters or super large pipe diameters

Abstract

The invention discloses a combined type cut-off device and a pipeline equipped with same. The combined type cut-off device comprises a mounting plate, a plurality of cut-off device bodies and a pressure source, wherein a plurality of mounting holes are formed in the mounting plate, and the mounting holes are transversely and / or longitudinally formed; one cut-off device body is mounted in each mounting hole, and the cut-off device body comprises a rubber sleeve, a circulating channel for allowing water flow to pass through is arranged in the rubber sleeve, and an inlet and outlet hole is formedin the cut-off device body; the pressure source is connected to the inlet and outlet hole of each cut-off device body through a conveying pipeline, and is used for pressurizing each cut-off device body and releasing the circulating channel to cut off or conduct. According to the combined type cut-off device disclosed by the invention, the cut-off device is transversely and longitudinally combinedinto an integrated structure, and can be combined according to the size of the pipeline or a discharge hole, so that the combined type cut-off device is wide in range of application, is small in pressure needed for control of single cut-off device, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a combined intercepting device and a pipe for installing the device. Background technique [0002] The flexible shutoff device is a kind of shutoff facility applied to the water outlet or outlet of the diversion well. Its structure generally includes an outer shell and a rubber sleeve. A pressurized cavity is formed between the outer shell and the rubber sleeve. The end of the rubber sleeve The upper part and the end of the outer shell are sealed and connected by a flange. When the pressurized gas is filled into the pressurized cavity, the rubber sleeve is relatively inwardly deformed, the inner wall of the rubber sleeve is attached, and the circulation channel is closed. The diameter of the rubber sleeve is limited, and the deformation of the rubber sleeve is large. When the deformation is large, the end of the rubber sleeve slips out between the flange and the end of...
