Description
Technical field
The utility model relates to a kind of Vatch basin, in particular to a kind of underflow type Vatch basin that combined closure system is controllable belongs to city
City's municipal drainage equipment technical field.
Background technique
Vatch basin is the important structures in one of municipal drainage system, collects dry days in line sewage, and the abatement rainy day overflows
Stream pollution.When dry days, the sewage of discharge outlet along the river is shut off into sewage treatment plant；When the rainy day, part rain dirt mixed flow water is cut
Stream enters sewage treatment plant, and the rain dirt mixed flow water more than the ability of shutting off is discharged into surface water body.
Traditional Vatch basin has slot type, the weir weir Shi Hecao convolution, has the disadvantage that 1. design combined closure systems and objective need
The combined closure system difference asked is larger.Design combined closure system is that it is high to set different overflow weirs by centainly investigating and theoretical calculation
The measures such as degree determine；The combined closure system of objective demand is dirty according to the actual conditions of each row mouthful interflow mixed flow and overflow
What the ability of dye control requirement and urban sewage treatment system determined.The error of the two is very big, and height of weir plate is once setting
It is difficult to adjust.2. water drainage blocks water.Design discipline requires overflow weir to rise higher than river flood position to prevent river water from flowing backward, this is bound to
It is unsmooth to form water drainage.3. low efficiency of shutting off.It has usually been connected several Vatch basins by the main pipe that shuts off in drainage system, upper one
A well shut off after water shut off with next well before water mix after shut off again, mixed flow water is diluted step by step, eventually enters into sewage
The water concentration of system is low.4. depositing seriously polluted.What is shut off is mostly surface layer water body, and pipe, well deposition are seriously polluted, finally with heavy rain
It washes away one and is incorporated to river, influence Urban Water Environment.
In recent years, Vatch basin technology has certain improvement, and the gate valve of main reliable power manipulation substitutes fixed weir, real
Existing combined closure system is adjustable；There is the automated system according to the information such as rainfall, river water level control gate valve aperture；Reliable buoyancy control
Complicated transmission device of check valve opening, etc..These new technologies realize the controllable of combined closure system, but actually adjust combined closure system
Problem only needs to can be solved by 1~2 manual adjustment, and using complicated electromechanical equipment and automatic control equipment, necessity is not
By force, high failure rate, investment is big, O&M cost is high.In addition, the situations such as the water concentration that shuts off is low, water drainage blocks water still have.
Summary of the invention
The utility model is for combined closure system of the existing technology is difficult to control, the water concentration that shuts off is low, water drainage blocks water, river water
Flow backward, complex structure and other problems, provides a kind of can effectively improve and cut dirty efficiency, be adapted to water of shutting off, fair current is freely arranged, and reflux is inverse
Only, no mechanical equipment, high reliablity is with low investment, and O&M cost is low, is suitble to China's urban infrastructure status and demand for development
The controllable underflow type Vatch basin of combined closure system.
In order to achieve the above-mentioned object of the invention, the technical solution adopted in the utility model is to provide a kind of bottom that combined closure system is controllable
Streaming Vatch basin, including well body, well lid and mixed flow tube, the structure of Vatch basin are as follows: mixed flow tube pass through well body two sides, one end be into
Mouthful, the other end is outlet；The middle section bottom of mixed flow tube is provided with notch in well, and the outlet for the main pipe that shuts off, In are entered for mixed flow sewage
Pipeline leakage plugging device is socketed in well on mixed flow tube, the internal diameter of the pipeline leakage plugging device is identical as mixed flow pipe outside diameter, and length is greater than mixed flow bottom of the tube and cuts
Mouthful；Pipeline leakage plugging device is moved axially, changes the relative position of pipeline leakage plugging device and notch, for adjusting the flow of mixed flow outlet of sewer.
The bottom of well body described in the utility model be equipped with chute, the shaped upper part of chute arc low between the senior middle school of both sides,
The main pipe that shuts off is set among chute.
The outlet end of the mixed flow tube is oblique section, and flap valve is mounted on the outlet end of mixed flow tube.
Compared with prior art, the utility model has the beneficial effects that:
1. controllable combined closure system.By adjusting the relative position of pipeline leakage plugging device and mixed flow tube undercut, practical cut can adjust
The size of flow, effective amendment design error, makes it more meet objective requirement, under conditions of municipal sewage treatment ability is certain
Pollution load of overflow is utmostly controlled, meanwhile, it eliminates because of the resistance that drains flooded fields caused by shutting off.
2. underflow type mixed flow tube lower cut is used to enter the outlet for the main pipe that shuts off for mixed flow sewage, it can reach higher and shut off
Concentration, and can effectively solve the problems, such as to dilute step by step.
3. flap valve is mounted on mixed flow tube exit, the mixed flow water more than ability of shutting off can be arranged to surface water body, the row of realization
Water is unobstructed, moreover it is possible to prevent surface water body from flowing backward；Mixed flow tube discharge outlet is inclined-plane, is conducive to flap valve using self weight and preferably reaches close
The effect of apolipsis water.
4. the regulation of its combined closure system of Vatch basin provided by the utility model uses simple Hough section structure, complexity is not needed
Mechanical equipment, it is only necessary to by 1~2 manual adjustment, with higher reliability, the investment more saved and less O&M at
This characteristics of.
