Specific embodiment
Purpose and technical scheme for making the utility model embodiment is clearer, implements below in conjunction with the utility model
The accompanying drawing of example, the technical scheme to the utility model embodiment are clearly and completely described.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments.Based on described embodiment of the present utility model,
The every other embodiment obtained on the premise of without the need for creative work by those of ordinary skill in the art, belongs to this practicality
Novel protected scope.
The implication of " upper end, lower end " described in the utility model is referred to respect to equipment itself, rather than to this
The specific restriction of the equipment mechanism of utility model.
A kind of buoyancy tank flap valve as shown in Figure 1, including gate seat 3 and door closure 2；The gate seat 3 includes gas outlet 9 and carries
The fixed seat of centre bore；The fixed seat is arranged at the one end of gate seat 3；The gas outlet 9 is arranged on gate seat 3 near fixing
The side of seat；The door closure 2 is hollow structure, including mounting seat, filler port 4 and dumping pit 6；The mounting seat is located at door closure
2 one end；The filler port 4 is opened on door closure 2 side near mounting seat；The dumping pit 6 is arranged at the another of door closure 2
Relative position is on one end and with mounting seat；The installing hole of the mounting seat is connected by bearing pin 1 with the centre bore of fixed seat
Connect, door hinge is formed, can be rotated against between mounting seat and fixed seat, and door closure 2 is realized during rotating against
Folding to gate seat 3；Gate seat 3 may also be employed hinge means of the prior art with door closure 2 and link together in this application, with
Realize the laminating of door closure 2 and gate seat 3 and separate, (as door closure 2 covers tightly gate seat 3), door when door closure 2 is fitted completely with gate seat 3
Lid 2 realizes the effect for preventing water from pouring in down a chimney.
Apply less power for the ease of the open and close of door closure 2, more for the pressure when water level is too high, on door closure 2
Power can disperse to be transmitted on ground, and the gate seat 3 is inclined-plane in the end face that is fitted with door closure 2 completely.
The mounting seat is extending defining flange 7 along 2 radial line direction of door closure so that door closure 2 need to rotate low-angle model
Enclose and sealing gate seat 3 is achieved that, can also realize the purpose of flap valve headstock gear is reached using the hydraulic pressure differential force of fluid media (medium).
As preferred, also include 3 flange of gate seat, 3 flange of the gate seat is used for for gate seat 3 being connected to pipe-line system.
Used as preferred, door closure 2 is opened for convenience, also includes hoisting ring 5, and the hoisting ring 5 is provided with door closure 2 and leans on
The side of nearly dumping pit 6.
Further have, also include exhaust flange, the exhaust flange is installed on gas outlet 9, the gate seat 3 with door
Dovetail groove is offered on the face of 2 contact of lid；Sealing strip 8 is installed in the dovetail groove.
Implementation
Parallel direction according to mechanics principle by bearing pin 1 along door closure 2 with the radial direction of gate seat 3 is arranged, using fluid media (medium)
Hydraulic pressure differential force reaches the purpose of flap valve headstock gear.Wherein, gate seat 3 and door closure 2 are connected with bearing pin 1, blending bolt is adjusted fixes
Bearing pin 1, forms door hinge；Gate seat 3 is connected in pipe-line system by bolt and gate seat flange, by gas outlet 9 by welding and method
Orchid is connected on zinc-plated escape pipe；Filler port 4 and dumping pit 6 are welded on door closure 2, and become upper-lower position to be distributed, sealing strip 8
It is embedded in the dovetail groove of gate seat 3, gas outlet 9 is welded on gate seat 3；Before system work, counterweight material (can be water, sand, oil
Deng) add in door closure 2 from filler port 4, according to suitable volume is calculated, make the proportion of 2 weight of the door closure after counterweight and water
Requirement being reached, if added excessively, counterweight can be adjusted by 6 discharging of dumping pit；When system works, the model of water pump vane to flap valve
In enclosing, air (water pump is the water pump for being not required to vacuumize here, such as ZLB, QZ/QH type pump etc.) is, during drawing water, pipe
Air in road passes through outside 9 removal system of gas outlet, in order to keep pressure balance；When water flow to flap valve, rushing by current
Hit power to open flap valve, defining flange 7 can limit the angle of the unlatching of door closure 2 and can make the effect after the shutdown of flap valve water pump in gravity
Lower automatic rotary is posted together in gate seat 3；When upper pond level exceedes the height of water outlet side flap valve, due to the reality after 2 counterweight of door closure
The density of density slightly above water, therefore the effect that can realize preventing from pouring in down a chimney.
Embodiment of the present utility model is these are only, its description is more concrete and detailed, but therefore can not understand
It is the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, do not taking off
