In such scheme, shown in Figure 12, Figure 13, between described flexible rubber lobe 604 and valve body 601, be provided with hermetically-sealed construction 618.In the side that described hermetically-sealed construction 618 contacts with valve body 601 for flexible rubber lobe 604, protrude from the first protruding ring 6181 and second protruding ring 6182 of flexible rubber lobe 604, between described the first protruding ring 6181 and the second protruding ring 6182, be provided with groove 6183; The outer of described the first protruding ring 6181 is mutually vertical with described valve body 601; The protruding thickness of described the second protruding ring 6182 is greater than the thickness of the first protruding ring 6181, described the second protruding ring 6182 is to being in tilted layout along the direction of flexible rubber lobe 3 outers, and the flexible rubber lobe 604 of the rear end of described the second protruding ring 6182 is provided with the bending activity space 6184 for the second protruding ring 6182.When flexible rubber lobe 604 is in the time that valve body contacts, the air in groove 6183 is extruded, and now can realize ultralow pressure sealing.Hermetically-sealed construction 618 between flexible rubber lobe 604 and valve body 601, can realize low pressure (or with no pressure) time, only depending on flap is that the deadweight of flexible rubber lobe 604 just can be closed sealing, and not needing from gravity of sealing is simultaneously very large, can allow the unlatching damage by water of valve but very low; While having high pressure after valve, the hermetically-sealed construction of flexible rubber lobe in regime of elastic deformation, simultaneously.The activity space 6184 bending for the second protruding ring 6182, can reach under maximum working pressure flexible rubber lobe indeformable can ensure high pressure sealing time.

In such scheme, in conjunction with Figure 14, shown in Figure 15, described multistage adjustable overflow plate 6, it comprises the multiple dash weir plates 601 and the cleaning weir plate 602 that are vertically arranged on well body 1 runner, each weir plate is not on same vertical plane, clean weir plate 602 and be positioned at bottom, the bottom correspondence of each dash weir plate 601 is connected with the first axis of rotation 603, distance between the first axis of rotation 603 and the width of dash weir plate 601 match, between the first axis of rotation 603 and the dash weir plate 601 below it or cleaning weir plate 602, be provided with the first hermetically-sealed construction, the bottom of described cleaning weir plate 602 is fixed with the second axis of rotation 605, described the second axis of rotation 605 is positioned at the side, bottom of cleaning weir plate 602, the level of the central axis of described the second axis of rotation 605 and cleaning weir plate 602 is to central axis, vertical central axis is non-intersect, the bottom end face of described cleaning weir plate 602 is provided with the second hermetically-sealed construction, this second hermetically-sealed construction is made up of the second weather strip 607, the below of described the second axis of rotation 605 is provided with and the arc track 606 that cleans weir plate 602 bottom running orbits and match, described arc track 606 can be connected and be separated from each other with 602 basal slidings of cleaning weir plate, the angle of described arc track 606 is not more than 90 °, wherein one end of arc track (606) is positioned to be cleaned (as shown in figure 16) under the vertical central axis of weir plate 602.Wherein, the top end face of dash weir plate 601 is inclined-plane, and inclined-plane is provided with the first weather strip 604, the first weather strips 604 and forms described the first hermetically-sealed construction (as shown in figure 17).

Multistage adjustable overflow plate 6 drives the first axis of rotation 603 and the second axis of rotation 605 to overturn by drive unit, and then drive each dash weir plate 601 and clean weir plate 602 and overturn, realize the aperture of weir plate by the flip angle of axle, and then realize the control of multistage adjustable overflow plate 6 to water level and flow.In the time that dash weir plate 601 turn to level with cleaning weir plate 602, current maximum, in the time that dash weir plate 601 turn to vertical state with cleaning weir plate 602, all weir plates are in closure state.Wherein, the rotary movement control of the second axis of rotation 605 is cleaned the unlatching of weir plate 602 with closed, in the time cleaning weir plate 602 in closure state, clean weir plate 602 bottoms and arc track 606 in the state of being slidably connected, the two forms hermetically-sealed construction, and this structure has good sealing effect, structure is firm, long service life, without advantages such as jams, multistage adjustable overflow plate 6 now has the function of damming; Under the driving of the second axis of rotation 605, when 602 dextrorotations of cleaning weir plate go to 602b state, the bottom of cleaning weir plate 602 rotates to the other end of arc track 606, current maximum, now, owing to cleaning weir plate 602 bottoms and the still state in being slidably connected of arc track 606, current cannot flow through from well body 1 bottom, clean weir plate 602 and can play the stream effect of adjusting; Under the driving of the second axis of rotation 605, when cleaning weir plate 602 is rotated counterclockwise to 602a state, the bottom and the arc track 606 that clean weir plate 602 depart from, and current can flow through from the bottom of well body 1, can effectively clean well body 1 bottom, pile up problem to solve shaft bottom sediment.

This multistage adjustable overflow plate, owing to adopting the form of structure of multiple weir plates, can reduce each weir plate pressure-bearing, reduces weir plate side seal difficulty; Because lower shaft (the second axis of rotation) is arranged on well body bottom, easily cause the various sediments in water to be piled up in well body bottom, minimizing displacement accumulates over a long period, even can hinder the operation of axis of rotation, cause the phenomenon of lower shaft jam to occur, and this multistage adjustable overflow plate adopts two eccentric lower shafts to clean weir plate, can effectively clean well body bottom, avoid above-mentioned technical problem.

This catchpit is arranged on confluence of rainwater and sewage water inlet pipe and is received between natural water, and its course of work is as follows: in the time of dry season, sewage intercepting sewer 4 sewage that confluence of rainwater and sewage water inlet pipe 2 discharges that dams enters Wastewater Treatment Plant; While raining, when the liquid level in catchpit well body 1 does not exceed liquid level corresponding to sewage intercepting sewer 4 interception ratios, the floating drum flap valve 11 that dams is held open, and rainwater drains into Wastewater Treatment Plant by sewage intercepting sewer 4; In the time that the liquid level in catchpit exceedes liquid level corresponding to sewage intercepting sewer 4 interception ratios, the electronic flap valve 7 that dams is opened, rainwater covers just and flows into just rain intercepting sewer 9 by the electronic flap valve 7 that dams after rain overflow weir 10, floating drum dams flap valve 11 along with the rising of liquid level is slowly closed, first rain is dammed drains into Wastewater Treatment Plant, when liquid level is during lower than liquid level corresponding to interception ratio or the first rain of setting when time is up, the signal at stop that the electronic flap valve 7 that dams at first rain intercepting sewer 9 places provides by control room; In the time that liquid level exceedes multistage adjustable overflow plate 6 height, later stage rainwater directly overflows to natural water, and in the time that water level exceedes warning height, the upset above of multistage adjustable overflow plate 6 reduces the height of weir plate, with capable of increasing water discharge capacity.
