Description

Novel dirt guiding and draining sealing valve

Technical Field

The utility model relates to the technical field of underwater pollution discharge engineering, in particular to a novel pollution guide and drainage sealing valve.

Background

The sewage pipe under the river course is worn to establish in the concrete riverbed lateral wall, and sewage in the sewage pipe is usually led dirty pipe and is led dirty pipe and carry out drainage through cooperation on-shore suction pump and suction pipeline, just can concentrate the drainage treatment with the sewage in the sewage pipe. The drain pipe and the sewage guide pipe are usually sealed by a sealing valve, so that the sealing is free from leakage in the whole drainage process, and the sewage in the sewage pipe is ensured not to pollute river water.

However, the sealing valve needs to be detached under special conditions such as maintenance, cleaning and sewage discharge capability recovery of the sewage discharge pipe, and the sealing element can deform when the existing sealing valve is sealed by adopting a mechanical sealing assembly for the first time, so that the sealing capability is greatly reduced after the disassembly and the reinstallation, and the sealing effect and the sealing performance are reduced.

Disclosure of Invention

The technical scheme adopted by the utility model is as follows: the utility model provides a novel lead dirty drainage sealing valve, includes disk seat, valve gap and one end wear to establish the dirty pipe of leading in the blow off pipe, the disk seat is fixed on the concrete riverbed, and the valve gap covers on the disk seat, still includes sealed gum cover, gas tube and sealing ring, the one end that the blow off pipe was kept away from to the dirty pipe is passed the valve gap setting, sealed gum cover is established at the one end that the dirt pipe is located the blow off pipe, the one end and the sealed gum cover intercommunication of gas tube, the other end passes the valve gap setting, the inner wall of blow off pipe is tightly pushed up in the outside of sealed gum cover, the outer wall of dirt pipe is tightly led in the inboard top of sealed gum cover, the sealing ring cover is established on the blow off pipe, and the outer fringe setting of sealing ring is between disk seat and concrete riverbed.

Further, the outer wall of the sewage guide pipe, which is positioned at one end in the sewage discharge pipe, is provided with wavy anti-skid ribs.

Further, a plurality of pressure locks are arranged on the valve seat, one ends of the pressure locks are fixedly arranged on the valve seat through bolts, and the other ends of the pressure locks press the valve cover.

Further, the plurality of pressure locks are sequentially arranged at intervals along the circumferential direction of the valve cover.

Further, the valve seat is connected with the concrete river bed through a plurality of expansion bolts, and the expansion bolts are sequentially arranged at intervals along the circumferential direction of the valve seat.

Compared with the prior art, the utility model has the following beneficial effects: the novel dirt guiding and draining sealing valve is convenient to install and can be installed underwater; the air is easy to supplement, and the proper air pressure is maintained, so that the long-time effective sealing effect can be ensured; the sealing is convenient to release, the pressure lock catch is opened to take out the sewage guide pipe, so that the sewage discharge pipe can recover sewage discharge when needed; the sealing performance of the utility model is not affected by repeated disassembly and assembly.
