Description
Technical field
The utility model is related to water process, and in particular to a kind of rain dirt mixed flow pipe flow blocking device.
Background technology
For a long time, most cities old town only has the sewerage system of a set of pipe network, so that rain dirt mixed flow is dissipated row, i.e.,
Directly rainwater and sanitary sewage are discharged into the waters of near cities nearby using combined system, cause water body seriously to pollute, water quality
Drastically deteriorate, going to wreck property of water ecological setting is destroyed.Therefore it is imperative to be made as separate system for transformation interflow.But due to old
City to be transformed into two sets of pipe networks to rainwater and sewage carry out shunting discharge cost it is too high, so being transformed into shunting in combined system
During system, in order to cost-effective, a set of pipe network is still continued to use, the rainwater sewage of mixed flow is handled.Current most city
City uses interceptive combined system drainage system, in light rain season in dry season, sewage treatment plant's normal operation processing, but to flood season, it is special
When being not big amount of rainfall, since the load for the treatment of plant is limited, it is cost-effective, is directly arranged when amount of rainfall reaches a certain level
It puts, sewage treatment plant is out of service.But all it was to carry out behaviour of shutting off by manually closing sewage treatment plant's valve in the past
Make.Since sewage shuts off complicated adverse circumstances, the shortcomings of that there are maintenance costs is high for the operation, poor reliability.
Currently, domestic common sewage intercepting chamber is weir formula, slot type, slot weir formula etc., by sewage shut off main pipe position, close
The limitation of flow tube canal position, surrounding terrain, the water level elevation for discharging water body and emission point surrounding enviroment, old-fashioned Vatch basin are gradual
Many situations cannot be applicable in.

As illustrated in fig. 1 and 2, a kind of rain dirt mixed flow pipe flow blocking device may include the medium-sized flexible check valve 1 of pipe, air-driven type pipe
Folder valve 2, shut off wall 3 and externally positioned type flexible check valve 4.It manages medium-sized flexible check valve 1 and air-driven type pipe clip valve 2 is arranged in sewage and cuts
It flows on the connecting pipe 5 between well and catch-basin.Connecting pipe 5 can be arranged in sewage intercepting chamber and end catch-basin 720 it
Between, can also be arranged between sewage intercepting chamber 615 and the close closer catch-basin 713 of absolute altitude, i.e., sewage intercepting chamber with
In multiple catch-basins the absolute altitude of absolute altitude and the sewage intercepting chamber closest to and the catch-basin 713 nearest apart from the sewage intercepting chamber it
Between, as shown in Figure 1.In the case where the specification of storm sewer is DN450 and the specification of sewage conduct is DN300, connecting pipe
Specification be DN300.It is, of course, preferable to ground, connecting pipe 5 is less than 10 lis in the opening of catch-basin from rainwater bottom distance h1
Rice, so as to enter sewage conduct by water level official post dry flow sewage and initial rainwater gravity flow.Manage the use of medium-sized flexible check valve 1
In preventing the sewage in sewage intercepting chamber from entering catch-basin, i.e. water can only be flowed from catch-basin to sewage intercepting chamber.Air-driven type pipe
Folder valve 2 is for preventing excessive rainfall from entering sewage intercepting chamber, i.e., when amount of rainfall is larger, air-driven type pipe clip valve 2 is closed, at this time
Rainwater cannot enter sewage intercepting chamber by connecting pipe 5, to lower the burden of sewage disposal system.Air-driven type pipe clip valve 2 can
To manually control, also can be automatically controled.
Shut off wall 3 and externally positioned type flexible check valve 4 is mounted in end catch-basin 720.Wall 3 shut off by end catch-basin
720 are divided into upstream portion and downstream part, and upstream portion is connected to upstream catch-basin, and downstream part is connected to river.Shut off wall 3
For preventing the water in river from entering in end catch-basin 720, and the rainwater in upstream portion can overflow across and shut off under the entrance of wall 3
Part is swum, and then is discharged in river.Preferably, shut off wall 3 well head distance h2 of the upper end from catch-basin at 10-20 centimetres.
Externally positioned type flexible check valve 4 is mounted on the water inlet line exit of end catch-basin 720, for preventing in end catch-basin 720
Rainwater flow back to upstream catch-basin.
In addition, the rain dirt mixed flow pipe flow blocking device may also include level measurement device (not shown), setting is being arranged
Have in the catch-basin 713 of connecting pipe, is acted for triggering air-driven type pipe clip valve 2.I.e. when the water that level measurement device detects
When position is more than predetermined value, air-driven type pipe clip valve 2 is closed.Preferably, which is float type water level measuring device.
Now briefly explain the course of work of the utility model.When dry days, intercepting sewage enters sewage system by gravity flow
System, when the rainy day, initial rainwater can be also trapped, and when amount of rainfall is larger, rainwater can be cut by overflowing across after closing air-driven type pipe clip valve 2
It flows wall 3 and enters river, manage the sewage that medium-sized flexible check valve 1 avoids in sewage conduct and pass through connecting pipe 5 and storm sewer
Overflow to river.
The preferred embodiment of the utility model has already been described in detail above, it is understood that if desired, embodiment can be changed
Aspect using the aspect, feature and design of various patents, application and publication provide other embodiment.
