Background technology
In recent years, wastewater treatment in China industry is advanced by leaps and bounds, and overall development is in the fast-growing period, is mainly manifested in sewage
The aspects such as disposal ability is expanded rapidly, wastewater treatment rate steadily improves, sewage load quickly growth.Each technique of sewage disposal
The monitoring of link inlet/outlet water quality index is for instructing and ensureing that vital work is played in sewage disposal system stable operation
With.In view of equipment investment cost, most sewage treatment plants only achieve terminal water outlet on-line monitoring, for intermediate link
Water quality index monitoring all use the mode of chemical examination after manual sampling.
The structures of large and medium-sized sewage treatment plant are many and high, and the sample point quantity needing monitoring is more, and manual sampling is often
Need the climbing operation repeated.Such sampling working method not only waste of manpower and time, and there is certain danger.
Utility model content
This utility model is for structures high in sewage disposal system such as cesspool, retort or the entry/exit of reaction tower class
Water sampling work is dangerous and a difficult problem for time-consuming length and a kind of automatic back flow of designing the sampling line that can detect waste liquid, it is achieved that
The method utilizing ordinarily manometer interface side to install sampler additional, solves the entry/exit of high structures in sewage disposal system
Water sampling work is dangerous and a difficult problem for time-consuming length, and installing observation bottle additional, to make operator can observe liquid in outside pure
Degree, if occurring contamination accident can stop taking liquid.
The technical scheme provided is:
Providing a kind of automatic back flow and can detect the sampling line of waste liquid, it includes main line, is provided with on main line
Piezometer, is positioned at main line and is provided with the first arm and the second arm, the first arm is fitted with the first check valve, the second arm
On be fitted with the second check valve, the first arm is switched to the first interface of threeway, and the second arm is switched to the second interface of threeway,
Connecting on 3rd interface of threeway and have liquid flowing tube, liquid flowing tube is provided with flow speed control valve, the water outlet connection at liquid flowing tube takes
Liquid flexible pipe.
Further, between the first described arm and the second arm, be provided with many balance pipes, each balance pipe respectively with
First arm and the second arm are connected.
Further, connecting and have observing tube on liquid flowing tube, observing tube and is observed bottle and is connected.
Further, described observation bottle is positioned at above liquid flowing tube.
Further, being also associated with return duct on liquid flowing tube, return tank is connected with main line, installs in loop pipe
There is electromagnetic valve.
Further, the described liquid flexible pipe that takes is polyurethane flexible pipe.
This utility model is compared relative to prior art and is had the advantages that
This utility model simple in construction, possesses pressure measxurement and two kinds of functions of fluid sampling and can observe pot liquid constantly
Degree of purity, once finds dirty liquid, liquid can be refluxed electric conduction magnet valve, and alarm is shut down.
By installing probe tube additional in pressure measuring device storage, great convenience sampling operation loaded down with trivial details degree, directly operation takes
Sample, reduces operator's danger, discharges potential risk.
By the arm arranged on each branch road, and arm is coupled together by balance pipe, it is ensured that each arm
Internal pressure is equal, increases a tube lifetime, prevents from producing incident of leakage because pressure is uneven.
Accompanying drawing explanation
Fig. 1 is the annexation figure that this utility model is overall；
Reference in figure is: main line 1, piezometer the 2, first check valve the 3, second check valve the 4, first arm 5,
Two arms 6, balance pipe 7, threeway 8, observation bottle 9, liquid flowing tube 10, flow speed control valve 11, return duct 12, electromagnetic valve 13
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further details
As it is shown in figure 1, this utility model provides a kind of automatic back flow and can detect the sampling line of waste liquid, it includes main
Pipeline 1, is provided with piezometer 2 on main line, is positioned at main line and is provided with the first arm 5 and the second arm 6, the first arm and
Two arms are parallel, are provided with many balance pipes 7 between the first described arm and the second arm, and each balance pipe is respectively with first
Arm and the second arm are connected, and each balance pipe and the first arm and the second arm mutually orthogonal one-tenth work shape, on the first arm
Being fitted with the first check valve 3, the second arm is fitted with the second check valve 4, the first arm is switched to the first interface of threeway 8,
Second arm is switched to the second interface of threeway, and the 3rd interface of threeway connects liquid flowing tube 10, and connecting on liquid flowing tube has
Observing tube, observing tube and is observed bottle 9 and is connected.Described observation bottle is positioned at above liquid flowing tube, is also associated with on liquid flowing tube
Return duct 12, return tank is connected with main line, is provided with electromagnetic valve 13 in loop pipe, and liquid flowing tube is provided with flow speed control valve
11, the water outlet connection at liquid flowing tube takes liquid flexible pipe.
It is polyurethane flexible pipe for ensureing the liquid flexible pipe that takes described in operation facility.
Below according to accompanying drawing, use mechanism of the present utility model is illustrated:
In normal work, closed electromagnetic valve, the liquid in main line is i.e. aggregated into by the first arm and the second arm
In liquid flowing tube, and observed liquid color pouring in observation bottle through observation bottle by external staff, when confirming that liquid color is normal
After the liquid after normal filtration, opening flow speed control valve, liquid is i.e. flowed out through taking liquid flexible pipe by liquid flowing tube.
Being positioned at above liquid flowing tube because observing bottle, observing the liquid in bottle and automatic the most slowly inflow can take liquid under gravity
Manage such main line liquid and can slowly pour in liquid flowing tube through liquid flowing tube, the liquid within main line, no matter in main line
Liquid quality how, and the liquid in main line all can enter in observation bottle, thus observes for external staff.
When the liquid in observing in bottle is the discovery that dirty liquid, opens the backflow of electromagnetic valve liquid i.e. Liu Jing return duct and become owner of
In pipeline, observer's hard stop blowdown, search leakage point.
