Afterwards, in the presence of the gravity and impulsive force of water, annular piston 240 slides down to the position under the second through hole k2, now
Second through hole k2 connection first through hole k1, upper chamber q2 and second channel t2, hydrops can be from first through hole k1 through upper chamber
Q2, from the second through hole k2 second channel t2 is flow to, and is then discharged downwards, so as to realize the exclusion of same lamination water.When hydrops it is drained
Afterwards, annular piston 240 in the presence of the support force of spring 260 upward sliding to the second through hole k2；Now, first through hole
Separated by annular piston 240 between k1 and the second through hole k2, it is ensured that the foul smell in second channel t2 holes is returned out from first through hole k1, shadow
Ring the air quality of peripheral space.
Continuing with referring to Fig. 2, Fig. 4, in the present embodiment, it is preferred that the diapire 222 of annular wall 220 is additionally provided with threeway
Hole k3.Arrange third through-hole k3 main purpose be prevent from first through hole k1 exclude with lamination water when second channel t2 in
The water for drainage jam occur is returned out through upper chamber q2 from the second through hole k2 from first through hole k1.It is being not provided with third through-hole k3
When, when being located under the second through hole k2 in the presence of gravity of the annular piston 240 when same lamination water is excluded and impulsive force, if
Occur drainage jam phenomenon in second channel t2, when substantial amounts of water and cannot at present be arranged and rested in water-drainage tube part 010, these
Water may be flowed into from the second through hole k2, be flowed out from first through hole k1 through upper chamber q2.Obviously, this is not allow appearance.
And third through-hole k3 is provided with the present embodiment, when occurring drainage jam phenomenon in second channel t2, substantial amounts of water cannot be timely
Lower row and when resting in water-drainage tube part 010, these water first can enter lower chambers q3 from third through-hole k3, so as to throw-out collar upwards
Shape piston 240 so that annular piston 240 closes the runner between first through hole k1 and the second through hole k2, it is to avoid second channel
The water being detained in t2 returns out first through hole k1.
Continuing with referring to Fig. 2, Fig. 3, Fig. 4, in the present embodiment, it is preferred that upper pipe fitting 100 also includes valve plate 130, first
The lower end of body 110 is connected with two relative hangers 140, and valve plate 130 is rotated by the bearing pin 150 through two hangers 140
It is matched with the lower ending opening of the first body 110；The two ends of bearing pin 150 have been respectively fixedly connected with travelling gear 151.Piston connects
There are two relative drive links 250, two drive links 250 are each passed through third through-hole k3, and drive link 250 away from annular piston
240 one end is provided with the driving rack 251 for being engaged with travelling gear 151.Alternatively, drive link 250 passes through spring
260, to also serve as the guide frame of spring 260.When position of the annular piston 240 in the raw or under its naturalness
When putting, the normal of valve plate 130 perpendicular to upper pipe fitting 100 axis so that the lower ending opening of upper pipe fitting 100 is opened to maximum；When
When annular piston 240 is moved up to more than its naturalness position, driving rack 251 engages band with travelling gear 151
Dynamic valve plate 130 rotates to reduce the lower ending opening of upper pipe fitting 100.When driving rack 251 and travelling gear 151 are not engaged, valve plate
130 normal perpendicular to upper pipe fitting 100 axis so that the lower ending opening of upper pipe fitting 100 is opened to maximum, it is ensured that maximum row
Water speed；When there is drainage jam in second channel t2, block up stagnant water and enter in lower chambers q3 from third through-hole k3, promote ring
The upward sliding of shape piston 240, on the one hand closes the passage of first through hole k1 and the second through hole k2, it is to avoid water is returned from the second through hole k2
Go out；Other direction, the annular piston 240 of upper cunning drives the drive link 250 being connected on annular piston 240 up, by connection
In drive link 250 away between the driving rack 251 of one end of annular piston 240 and the travelling gear 151 for being connected to bearing pin 150
Engagement drive bearing pin 150 connection valve plate 130 rotate, to reduce the openings of sizes of the first pipe fitting lower end, so as to reduce top stream
Under water amount, give time for draining of stifled stagnant water of lower section, realization is dredged and eliminated and blocks up stagnant water, makes draining back to normal
Effect.Naturalness finger ring shape piston 240 described at this is not received to arrange the gravity of hydrops and acting on for impulsive force, Jin Jin
State under the support of the support force of its deadweight and spring 260.
Further embodiment in the present embodiment also has can avoid standpipe from water occur during drainage jam from same layer
Hydrops exclude passage and return out and reduce when drainage jam occurs in standpipe upper strata displacement, promote draining for stifled stagnant water.
Further, the side relative with bearing pin 150 of valve plate 130 is fixedly connected with counterweight 131.In its natural state, valve
The side of the connection counterweight 131 of plate 130 is located at bottom, enables valve plate 130 to keep full-gear, i.e., in making upper pipe fitting 100
Lower ending opening is opened to maximum state.Guarantee that general state can keep maximum drainage speed.
Up big and down small taper pipeline section is removably connected with continuing with the lower end referring to Fig. 2, the lower pipe fitting 200 of the present embodiment
400, the lower end of taper pipeline section 400 is connected with straight length 500.It is set to be detachably connected at this and facilitates the structures such as drive link 250
Installation.
In sum, the water-drainage tube part 010 in the present embodiment has can simultaneously realize standpipe draining and arrange with lamination water
The function of removing, and the passage can be separated when same lamination water is not excluded for, it is to avoid standpipe back foul.It is further in the present embodiment
Also there is embodiment water when standpipe can be avoided drainage jam occur to return out from same lamination water exclusion passage and occur in standpipe
Reduce upper strata displacement during drainage jam, the effect of stifled stagnant water is dredged and eliminated in realization.
