Cut-off device with capsule, distributing well and control system thereof

Abstract

The invention provides a cut-off device. The device comprises a capsule and an outer cover, wherein the capsule forms a flow channel through which fluid is allowed to pass, a containing air cavity orwater cavity is formed inside the flow channel, and the capsule is provided with an inlet to be communicated with the air cavity or water cavity; the outer cover covers the capsule, the inner side ofthe outer cover is matched with the outer surface of the outer wall of the capsule, when pressure gas or pressure water is introduced into the air cavity or water cavity, the outer wall of the capsuleand the inner wall of the outer cover are attached so that the inner wall of the capsule deforms inwards and expands, and therefore the sectional area of the flow channel becomes smaller. Due to thefact that the capsule of dual layers is internally provided with the containing air cavity or water cavity, the capsule is provided with the inlet to be communicated with the air cavity or water cavity, in other words, the whole device can only adopt two components, no other fastener is adopted, replacement can be performed just by pulling out the capsule from the outer cover, and operation is convenient and rapid.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to an intercepting device, a diversion well equipped with the intercepting device and a control system thereof. Background technique [0002] At present, in the diversion well, abandonment well and interception well system, the system is composed of water inlet pipe, water outlet pipe and sewage intercepting pipe, which divert the domestic sewage in the drainage pipe or the initial rainwater and later rainwater, among which the domestic sewage Or the initial rainwater is intercepted to the sewage pipe and then transported to the sewage treatment plant for treatment and discharged after reaching the standard (further, the initial rainwater can be stored or intercepted to the sewage treatment plant for treatment and discharged after reaching the standard). in a body of water. [0003] In reality, whether it is a rainwater pipe of a diversion system or a sewage pipe or a confluenc...

AI Technical Summary

Problems solved by technology

However, in reality, electric control has the following problems: 1. Generally, flammable and explosive biogas will be produced in closed pipelines and sewage environments. General electric control devices are prone to explosion and unsafe. Therefore, when using electric control devices It is required that the electronic control part in contact with the biogas must have an explosion-proof function, so the price of the electronic control system is relatively expensive and the cost is high; 2. In the severe environment of stormy weather, power failure will occur, and the power will be diverted after power failure The equipment in the diversion well, abandonment well or interception well cannot work normally, resulting in urban waterlogging and other situations; 3. In rainy weather, the flooding of diversion wells, abandonment wells and interception wells ranges from several hours to several days In this way, the use of an electronic control device that is completely suitable for underwater use will be too redundant and cost too high, and the commonly used IP68-level electronic control device can be submerged within a few hours, and there are also situations where the capacity is insufficient; 4. The devices of the electric control system use unsafe voltage, and the high voltage is unsafe and prone to accidents; 5. After the electrical equipment is flooded, it is easy to leak electricity and there is a risk of electric shock; 6. When the electric control equipment (gates, weirs) are running It needs an upward or downward journey, which exposes the urban ground, which affects the urban landscape and traffic, and the excavation area is large during construction; 7. The electric control system uses 380V three-phase electricity, and the municipal power grid cannot supply power, so there is a problem of power supply difficulty question

[0004] In particular, for the occasions requiring concealed installation, and the power supply and costs of the electronic control system are not easy to solve

There are also certain problems in hydraulic control: the hydraulic station uses high-pressure oil pipes, and the cost of the hydraulic station and high-pressure oil pipes is relatively high; the rupture of high-pressure oil pipes will pollute the environment; after the electrical equipment is flooded, it is easy to leak electricity and there is a risk of electric shock; Gates, weir gates) require upward or downward strokes during operation, exposing the urban ground, affecting the urban landscape and traffic, and the excavation area is large during construction
