The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Shown in Fig. 1,2, it is the structural representation of the trapped well in standard collective drawings, comprise well body 1, on the borehole wall of well body, level is provided with a water inlet pipe 2 and an outlet pipe 3, the water side of water inlet pipe and the water intake end of outlet pipe respectively are provided with a threeway 4, the top of threeway is provided with stopper 7, and the threeway bottom is provided with short tube 5, and short tube 5 is provided with support 6.
Below the gauge table of standard collective drawings trapped well:
Gauge table
| Model | Caliber | A | B | h | Walling crib |
| GS-1 | DN75~DN200 | 1000 | 1000 | ≤1000 | (9) |
| GS-2 | DN75~DN200 | 1250 | 1000 | ≤2000 | (11) |
The trapped well of this kind of structure is only applicable to the linear pattern situation that the pipeline nominal diameter is DN75-DN200mm.
But 90 degree turn-type or the triplet type situations that nominal diameter DN75-DN600mm occurred in actual use, spend the water seal problem of the oily waste water drainage pipe of turn-types or triplet type situation in order to meet DN75-DN600mm heavy caliber and 90, the utility model provides a kind of oily waste water drainage pipe trapped well, can meet the instructions for use in Practical Project.
The oily waste water drainage pipe trapped well that the utility model provides, comprise well body 1, and on the well body sidewall, level is equipped with at least two water inlet pipes 2 and an outlet pipe 3; The water intake end of the water side of water inlet pipe 2 and outlet pipe 3 respectively is connected an equal tee 4, and the bottom of equal tee 4 is provided with short tube 5, and it is stretched in water, guarantee effective water seal, water seal height is at least 250mm, and equal tee 4 tops are provided with stopper 7, prevents that oily waste water from flowing out from top; Short tube 5 is provided with support 6, play fixed supporting role.The water inlet pipe setting height(from bottom) is at least higher than outlet pipe setting height(from bottom) 100mm, and the assurance oily waste water can be discharged smoothly by gravitional force.Water seal height by the outlet pipe bottom surface apart from the distance of connection equal tee short tube bottom surface.
Wherein, the nominal diameter scope of water inlet pipe and outlet pipe is DN75～DN600mm.When a water inlet pipe accesses separately, this water inlet pipe can also can become with outlet pipe 90 Du She Ge with outlet pipe Dui Cheng She Ge, so trapped well can be made linear pattern or 90 degree turn-types; When two water inlet pipes access from 2 different directions simultaneously, trapped well can be made triplet type.
