On, one end of valve rod is extended in the delivery port 11 of the first outlet pipe 10, and valve rod axial displacement in delivery port 11 can drive sealing
Flap 12 controls the opening and closing of the delivery port 11 of the first outlet pipe 10, wherein, valve rod includes the installation for being available for sealing flap 12 to install
Seat 13, is circumferentially provided with least two spaced guide plates 14 in mounting seat 13, at least two guide plates 14 extend the
In the delivery port 11 of one outlet pipe 10.Valve rod is arranged to said structure, primarily to convenient install, in the process installed
In, at least two spaced guide plates have deformation, contractile ability.
The side of delivery port 11 of the first outlet pipe 10 is provided with the second outlet pipe 15, the second outlet pipe 15 and the first outlet pipe
Sealing leather bag 16 is provided between 10, the outer ring sealing for sealing leather bag 16 is located between the first outlet pipe 10 and the second outlet pipe 15
Junction, inner ring are seal-installed on the delivery port 11 of the first outlet pipe 10, then for the inner ring of more preferable fixing seal leather bag,
Necking part 17 is provided with the delivery port of the first outlet pipe 10, platform is formed between the delivery port of the outlet pipe 10 of necking part 17 and first
Rank.In the present embodiment, it is possible to further improve the stability that inner ring is installed, then the inner ring in sealing leather bag 16 is provided with annular
Groove, be provided with groove auxiliary hold-down ring 19, seal leather bag 16 inner ring be closely attached on the outlet pipe 10 of necking part 17 and first it
Between step lateral surface.
Spacing preiection 20 is provided with guide plate 14 in above-mentioned laterally, valve rod is to the direction of the second outlet pipe 15 axial direction position
Move until stopping when spacing preiection 20 is moved at the step medial surface between necking part and the first outlet pipe.So by valve rod
When being installed in the delivery port of the first outlet pipe, due to being provided with fixed cover on the delivery port of the first outlet pipe, further, since leading
To the influence of the spacing preiection on plate, then can apply certain external force by valve rod by force to the delivery port of the first outlet pipe to valve rod
Middle press-in, during press-in, because spacing preiection receives inside extruding force, then can drive corresponding guide plate inside
Skew is shunk, until spacing preiection can then be resetted by fixed cover rear deflector.
On second outlet pipe 15 near junction between the first outlet pipe 10 and the second outlet pipe 15 be circumferentially provided with to
A few spilled water hole 21, when in working order, when the delivery port 22 of the second outlet pipe 15 is to 10 direction backwater of the first outlet pipe to
Inner side crush seal leather bag 16 causes that spilled water hole 21 is in open mode, and sealing flap now is because the pressure of backwater is by first
The delivery port of outlet pipe is closed, then recycling water utilization hydraulic pressure will seal leather bag 16 and be extruded to inner side so that sealing leather bag is no longer with the
Be adjacent between the inner tubal wall of two outlet pipes, 22 water outlet of delivery port from the delivery port of the first outlet pipe 10 to the second outlet pipe 15 when it is close
Strip of paper used for sealing capsule 16 resets and is adjacent to the madial wall of the second outlet pipe 15 so that spilled water hole 21 is closed, sealing flap now
Because the discharge pressure in the first outlet pipe pushes sealing flap open.So here sealing leather bag can be by the reset of itself
Ability resets, but to preferably reach the effect of reset, then can on the inner tubal wall of the first outlet pipe 10 circumferentially between
Every at least two support bars 24 are provided with, the inner end of support bar 24 is installed on the lateral wall of delivery port 11, the first outlet pipe 10
22 water outlet of delivery port from delivery port 11 to the second outlet pipe 15 when water by the backward outside extruding in the interval between support bar 24
Sealing leather bag 16, makes sealing leather bag 16 reset and is adjacent to the madial wall of the second outlet pipe 15 so that spilled water hole 21 is in closing shape
State.
In the present embodiment, for more preferable fixing seal leather bag, the outer tube wall of the first outlet pipe 10 is provided with annular
Erecting bed 25, the port of the installation end of the second outlet pipe 15 turns down to form mounting ring 23 laterally, and the outer ring for sealing leather bag 16 is close
Envelope is located between erecting bed 25 and mounting ring 23 and fixedly mounts；Spilled water hole 21 located at the second outlet pipe 15 installation end port with
The junction of mounting ring 23, by spilled water hole located at herein, primarily to improving the effect that sealing leather bag closes spilled water hole.In order to
So that the effect of sealing leather bag closing spilled water hole is more prominent, then the delivery port 11 of the first outlet pipe 10 is relative to the second outlet pipe
Distance of the distance of 15 delivery port 22 less than erecting bed 25 relative to the delivery port 22 of the second outlet pipe 15.While sealing flap
The external diameter of 12 delivery port 11 with diameter greater than the first outlet pipe 10, the internal diameter less than the second outlet pipe 15.In the present embodiment,
When being flowed back to preferably embody water, sealing leather bag can fast and effectively be extruded, can be on the lateral wall of sealing leather bag
Away from spilled water hole side set annular extruding raised line 18, then water be back to come when, first can crushing failure at high speed raised line, raised line is then
The inner tubal wall of the second outlet pipe can be rapidly separated with dynamic sealing leather bag, in order to avoid the mistake of the tube wall patch of sealing leather bag and the second outlet pipe
Cannot tightly depart from.
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
