Description
Technical field
This practicality relate to the dirty stopped flow technique field of rain, particularly the initial stage catchpit in closure works system.
Background technology
In the design of closure works system, the design of catchpit is most important, it should make the sewage dammed enter and cut dirty system, reach the object of regulation water environment, ensure again do not allowing the rainwater exceeding combined closure system enter into a section dirty system when raining heavyly, to prevent the actual flow of downstream wastewater interception pipe from exceeding design discharge, avoid occurring that sewage is counter emits and bring impact to Wastewater Treatment Plant.The determination of the maximum spillway discharge of catchpit is that its design-calculated is crucial, and current relevant design codes recommends the application conditions of design formulas, and General Requirements sewage intercepting chamber bleed off pipe bottom outlet elevation should more than water body flood level.But Practical Project is difficult to meet this condition, and be difficult to accurately control combined closure system.At present, adoptable modification measures mainly contains: 1. reduce intercepting sewer caliber, reduces discharge area; 2. combined regulation flashboard is set in catchpit, less flashboard standard-sized sheet during dry season, during rainy season, regulates the control realizing combined closure system compared with the open degree of big damper.Although these two kinds of measures can control to enter the amount of rainfall of main of damming to a certain extent, all there is the feature that flow-control inaccuracy, operability are poor.
Summary of the invention
This practical purpose is for deficiency of the prior art, provides a kind of primary rainwater closure well, and it can accurate flow control, and simple operation, high range request is low, without the need to periodic maintenance.
For realizing the goal of the invention of this practicality, by the following technical solutions:
A kind of primary rainwater closure well of the present utility model, it comprises: well body, well lid is equipped with in the upper end of well body, rainwater water inlet pipe and rainwater outlet pipe is connected near the bottom of well body, wherein: well body is built with overfall, and well body is divided into inhalant region and exhalant region by overfall, and rainwater water inlet pipe leads to inhalant region, rainwater outlet pipe leads to exhalant region, and the well body of the inhalant region lower than overfall height is also equipped with throttle pipe;
A kind of primary rainwater closure well of the present utility model, wherein: described throttle pipe is equipped with rotational flow-limiting valve;
A kind of primary rainwater closure well of the present utility model, wherein: the diameter of described rainwater water inlet pipe is identical with the diameter of rainwater outlet pipe, and has sustained height, the height of overfall is the 1/2-2/3 of the maximum height of rainwater water inlet pipe and rainwater outlet pipe;
A kind of primary rainwater closure well of the present utility model, wherein: described throttle pipe diameter is the 1/5-1/4 of rainwater water inlet pipe diameter.
Compared with prior art, primary rainwater closure well beneficial effect of the present utility model is: convenient for installation and maintenance, technique is simple, breach rain dirty catchpit combined closure system and control the poor restriction of inaccuracy, operability, accurately can control flow, it is comparatively convenient to operate.By the primary rainwater closure well of this form, it achieves and only relies on current to reach the object of limited flow, and can accurately control to cut dirty flow rainy season, its accuracy can reach 0.1L/s, and the rainfall being less than a certain numerical value is all dammed, greatly reduce the pollution of rainwater to natural stream networks.High range request is low.

Detailed description of the invention
As depicted in figs. 1 and 2, primary rainwater closure well of the present utility model comprises: well body 2, well lid 1 is equipped with in the upper end of well body 2, rainwater water inlet pipe 3 and rainwater outlet pipe 6 is connected near the bottom of well body 2, well body 2 is built with overfall 5, well body 2 is divided into inhalant region 8 and exhalant region 9 by overfall 5, rainwater water inlet pipe 3 leads to inhalant region 8, rainwater outlet pipe 6 leads to exhalant region 9, the diameter of rainwater water inlet pipe 3 is identical with the diameter of rainwater outlet pipe 6, and have sustained height, the height of overfall 5 is the 1/2-2/3 of the maximum height of rainwater water inlet pipe 3 and rainwater outlet pipe 6.Lower than overfall 5 height inhalant region 8 well body 2 on throttle pipe 4 is also housed, throttle pipe 4 diameter be rainwater water inlet pipe 3 diameter 1/5-1/4.Rotational flow-limiting valve 7 throttle pipe 4 is equipped with, directly entered in sewage reservoir by the rainwater after rotational flow-limiting valve 7, rotational flow-limiting valve 7 is housed makes the amount of rainfall entered in sewage reservoir keep constant, can not bring fluctuation because of the fluctuation of the amount of rainfall entered to the production of sewage reservoir.
As shown in Figure 1, when rainwater flows into rotational flow-limiting valve 7 through throttle pipe 4, the effect of the cavity special due to rotational flow-limiting valve 7 and eddy flow core ventilation opening, the flow of rainwater is made to maintain constant state, avoid bringing impact to Wastewater Treatment Plant, through the rainwater of rotational flow-limiting valve 7, flow out from the outlet of rotational flow-limiting valve 7, flow into Wastewater Treatment Plant subsequently, from rainwater outlet pipe 6 flow out rainwater enter as: the natural stream networks in river etc., rotational flow-limiting valve 7 uses the patent No. to be: ZL200920105898.3 utility model patent, denomination of invention is: flow automatic control eddy flow valve.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within claims of the present utility model.
