Horizontal Rotary Blocking Door

Abstract

The invention discloses a horizontal rotary plugging door which comprises a pipeline, wherein the pipeline end surface on the peripheral edge of a pipeline port is inclined; supporting seats are arranged on the pipeline end surface in a bilateral symmetry way; an eccentric plugging door is connected between the supporting seats; a rotating shaft and an axial adjustable sealing plate are arranged on the eccentric plugging door; the rotating shaft is hinged to the supporting seats; a rotational driving mechanism is connected with the rotating shaft; the axial adjustable sealing plate is hermetically matched with the pipeline end surface; a central axis of the rotating shaft is not crossed with that of the pipeline port. According to the horizontal rotary plugging door disclosed by the invention, the seal fit can meet the requirements through adjusting the axial position of the axial adjustable sealing plate, so that the sealing effect is ensured, the over-large opening and closing torque is not caused, the flexible mobility of the plugging door is improved, and the mounting and positioning difficulty of the plugging door is greatly reduced; in addition, as the pipeline end surface is inclined, the operation space is enlarged, and the intrusion of rainwater and sewage in the pipeline is effectively prevented, so that the plugging door is more flexible in action and longer in service life.

Description

technical field [0001] The invention relates to drainage equipment, in particular to a horizontal rotary blocking door. Background technique [0002] The rainwater and sewage in the drainage pipes are usually discharged by gravity, and the flow rate in the pipes is generally low. The pipes are often blocked due to the accumulation of sediment and other sediments in the pipes. Moreover, some sediments will produce toxic gases to corrode the pipes. Therefore, it is necessary to regularly Plug and flush the pipeline; when overhauling the pipeline, it is also necessary to seal the pipeline. At present, the pipeline blocking door has the following disadvantages: 1) The installation and positioning of the blocking door is difficult, so that the sealing fit is either too tight or too loose. If the sealing fit is too tight, the opening and closing torque will be large, and if the sealing fit is too loose, the sealing effect will not be guaranteed. 2) when the blocking door is fully...

Problems solved by technology

At present, the pipeline blocking door has the following disadvantages: 1) The installation and positioning of the blocking door is difficult, so that the sealing fit is either too tight or too loose. If the sealing fit is too tight, the opening and closing torque will be large, and if the sealing fit is too loose, the sealing effect will not be guaranteed. ; 2) When the blocking door is fully opened, part of its structure is still on the water flow channel, which not only hinders the water flow, but also is easily eroded by sewage, and the service life of the parts is short
