Description

Horizontal Rotary Blocking Door

technical field

The invention relates to drainage equipment, in particular to a horizontal rotary blocking door.

Background technique

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 opened, its part 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 parts is short.

Contents of the invention

The object of the present invention is to provide a horizontal rotary blocking door, the sealing and matching structure of which is adjustable, and when the blocking door is fully opened, there is no hindrance to the water flow channel.

In order to achieve the above object, the technical solution adopted by the present invention is: a horizontal rotary blocking door, including a pipeline, the pipeline end surface around the pipeline port is inclined, and the left and right symmetrical support seats are arranged on the pipeline end surface.

The invention drives the rotating shaft to rotate, and then drives the eccentric blocking door to rotate, so that the eccentric blocking door can be opened and closed quickly; the eccentric design makes the eccentric blocking door and the end surface of the pipeline contact only at the moment of opening and closing to form friction, and the opening and closing torque is small. Long service life; the invention can make the sealing fit meet the required requirements by adjusting the axial position of the axially adjustable sealing plate, which not only ensures the sealing effect, but also prevents the opening and closing torque from being too large, and improves the flexibility of the blocking door , which greatly reduces the difficulty of installation and positioning of the plugging door; at the same time, the plugging door can block extremely high water levels, which can be used not only for flushing pipelines, but also for pipeline plugging, with good flushing effect and reliable plugging; In this blocking door, the end surface of the pipeline is made into an inclined slope, and then the eccentric blocking door is installed on it. Compared with the installation on the vertical pipeline end surface, the present invention has a larger operating space and more convenient installation. The height of the mechanism and the rotating shaft increases the distance between it and the water surface, which can more effectively prevent the intrusion of rainwater and sewage in the pipeline, protect the components such as the rotating drive mechanism and the rotating shaft, and make the horizontal rotary blocking door move It is more flexible and has a longer service life; the blocking door has simple structure, good manufacturability, wide application range and low cost.
