Preferably, the circumference of base 9 is provided with three fixing holes 14, and base 9 is fixedly connected with partition wall 2 by the securing member running through fixing hole 14.Such as, during installation, base 9 to be stabilized in cement mortar and to be fixed on partition wall with 3 setscrews.In installation process, to make odor-proof escape flap valve 8 perpendicular to ground, and base 9 and door-plate 10 are closed closely as spending.
Preferably, the top of base 9 is provided with the first fraising 12 between two parties, and the top of door-plate 10 is provided with the second fraising 13 between two parties, base 9 and door-plate 10 by the first fraising 12 and the second fraising 13 hinged.
Preferably, base 9 is rounded, and door-plate 10 is rounded.In one embodiment, the main body of base 9 is an annulus, and internal diameter is identical with the external diameter of hole 5, and annular width is 20mm.Door-plate 10 is a circular flat board, and diameter is identical with the external diameter of base 9, is 240mm.It is hinged that base 9 and door-plate 10 pass through hinge, and hinge should have certain Rigidity and strength, and diameter is slightly less than the aperture of the first fraising 12 and the second fraising 13, is beneficial to the keying of door-plate 10.
Preferably, odor-proof escapes flap valve 8 and adopts UPVC material to make.Preferably, cover plate 7 is compound resin cover plate.
Embodiment:
With the newly-built combined sewerage pipeline in community, Xuzhou City for object, optionally wherein 5 connected inlets for stom water are changed into heavy mud odor-proof and are escaped inlet for stom water, carry out odor-proof and escape flap valve 8 and open and close flexibility, heavy mud amount and stop that foul smell escapes the test of effect.Selected connect concrete pipe that gutter 11 is internal diameter 300mm, design length 2.0m, starting point thickness of earth covering be 0.7m, design grade 3%, inlet for stom water spacing 25m; The manhole connected with being connected gutter 11 is the brick circular closing in type sewage inspection well of φ 1250mm; The pipeline section total length adopting heavy mud odor-proof to escape inlet for stom water is 100m, is positioned at the middle part of whole design pipeline section.Before test, the foreign material in the utility model are cleaned out, in order to avoid affect test result.
A. odor-proof escapes flap valve and opens and closes flexibility test
Select representational certain rainfall to carry out odor-proof by ruler and protractor and escape flap valve keying flexibility test, get 5 odor-proofs and escape the average of flap valve test value as measured value, the results are shown in Table 1.
Table 1 odor-proof escapes flap valve and opens and closes situation statistical form
As shown in Table 1: under verification condition, odor-proof escapes flap valve and opens and closes flexibly, and opening angle increases with the increase of rainwater degree of filling in hole, and when hole reaches maximum degree of filling, the maximum opening angle of flap valve is 71 °, can ensure that the rainwater in hole discharges rapidly; Rainfall stop after, along with the reduction of rainwater degree of filling in hole, door-plate 10 opening angle reduces gradually, and door-plate 10 falls after rise rapidly, until anhydrous in hole time and base closely sealed.
B. the test of heavy mud amount
Rainfall opens 5 water grates of the present utility model after stopping, and is all unwatered clearly by the sediment in mud sinking chamber 3 clean.Meanwhile, get 3 in the upstream of this test pipeline section, downstream gets 2 traditional inlets for stom water, and its sediment is all unwatered clearly clean.Weigh the sediment of each inlet for stom water after draining away the water respectively with electronic scale, and observe sediment situation in tube connector, the results are shown in Table 2.
Table 2 rainwater is fond of salty food mud amount statistical form
As shown in Table 2, under verification condition, in traditional inlet for stom water, heavy mud amount is little, and connecting in gutter at it has obvious visible sediment.In the utility model, in mud sinking chamber 3, sediment is than traditional inlet for stom water showed increased, but does not substantially have sediment in its connection gutter 11.Illustrate that sedimentation effect of the present utility model is better, decreasing and hypostasis matter can connect the sediment in gutter 11 in runoff rainwater, alleviating the clear and coherent maintenance work to connecting gutter 11.
C. stop that foul smell escapes measure of merit
By stopping to the method test flap valve of pedestrian's field investigation the effect that foul smell escapes.At high temperature season, select the period that two rainfall intervals are longer, before next rainfall is arrived for this section of Different age group pedestrian process to the sensation situation of stink, carried out field investigation, the results are shown in Table 3.
Table 3 pedestrian is to stink sensation condition survey table
As shown in Table 2, adopt the air quality in the utility model section to be obviously better than other section, illustrate that the utility model stops that foul smell escapes respond well.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
