Description
Technical field
The present invention relates to a kind of water lines automatic exhaust devices.
Background technology
Water-storage pump turbine spiral case is to realize that water can be converted into the important component of mechanical energy, spiral case normal operation phase
Between it is internal should be full of water, checked because that need to be periodically into spiral case, internal water emptied, when restoring water-filling, if there is gas residue
Energy conversion efficiency can be reduced, while aggravates turbine blade cavitation erosion, influences pump turbine service life.
Invention content
The object of the present invention is to provide a kind of water lines automatic exhaust devices, and water lines can not be automatic in the prior art for solution
The technological deficiency of exhaust.
To solve the above problems, the technical solution used in the present invention is：
A kind of water lines automatic exhaust device, including

Go out, specially the inflator in lower chamber enters from the bottom of upper inner cavity in upper cavity, and is discharged by the side of upper cavity.
Lower chamber, the lower cavity of the interior setting of the lower chamber, the upper and lower ends of the lower cavity extend through lower chamber
Upper surface and lower face, and lower cavity top and the diameter of bottom are less than the diameter at middle part, and the upper cavity is mounted on down
The top of cavity and upper plenum is communicated with lower cavity；Other most building blocks are installed, and air is under in lower chamber
Assemble in cavity, and be pressed onto air in upper cavity, and discharged by upper cavity from the lower inner cavity of lower chamber by water.
Hemispheric head cover, the outer surface of the head cover are matched with the curved surface of upper cavity bottom opening；Above and below head cover
Movement is used to open and is closed the opening of inner cavity, and head cover moves downward, and the opening of upper inner cavity is opened so that the gas in lower chamber
Body is discharged, and head cover moves upwards, and the opening of upper inner cavity is closed, and realizes the sealing of lower chamber.
Sleeve, the sleeve are made of the cylindrical portions on top and the round platform part of lower part, and wherein cylindrical portions is outer
Diameter is equal with the internal diameter on lower cavity top, and the top of sleeve outer surface is mutually fixed with the top of lower chamber, the circle of sleeve
Platform part is provided with water inlet；For sleeve for installing following floating drums, the round platform part of lower cartridge causes water inlet to contract,
The diameter of water inlet is less than the diameter of floating drum, for preventing floating drum from being fallen out of sleeve.
Floating drum, the floating drum are arranged in sleeve, and floating drum can move up and down in sleeve, the middle part of the floating drum
To be cylindric, to be round table-like, bottom is bent downwardly in can be with the matched cambered surface of water inlet on top；Water is from the water inlet of sleeve bottom
Mouth enters, and when the water surface rises, floating drum moves upwards under the buoyancy of water, head cover is pushed to move upwards head cover, in head cover
During moving upwards, the air more than the water surface is pressed into upper inner cavity and is discharged from upper inner cavity, and floating drum pushes away
Dynamic head cover is until the opening of the upper inner cavity of bottom cover closing；When water blocking is declines, floating drum moves downward, while head cover is due to the work of gravity
With moving downward naturally, so as to open the opening of upper inner cavity, it is ready for discharge next time air.
The present invention pushes floating drum and head cover to move up and down by the encouragement of water, automatically opens and be closed opening for upper cavity
Mouthful, so as to fulfill the purpose for discharging the air in lower chamber, solving water lines in the prior art can not self-bleeding skill
Art defect, and then energy conversion efficiency is improved, extend the service life of pump turbine.
As a further improvement on the present invention, the position of the upper cavity and lower chamber installation is provided with the rubber of annular
Sealing flange piece, the medial surface of the rubber seal flange plate are and the matched curved surface in the outer surface of head cover；Rubber is set
Sealing flange piece, on closing is moved up to after the opening of inner cavity, head cover is close together head cover with rubber seal flange plate,
Enhance whole sealing effect, prevent the water caused by sealing effect is bad from being flowed out along the outer surface of head cover.
As a further improvement on the present invention, guide rod is provided on the head cover, sets and is oriented in the upper plenum
Cylinder, the top of the guide rod are arranged in guide cylinder and can move up and down in guide cylinder；The cooperation of guide rod and guide cylinder makes
With playing the role of guiding to the up and down motion of head cover, prevent head cover from deflecting or coming off in displacement process, cause close
Envelope fails, and water is flowed out from this in pipeline.
As a further improvement on the present invention, the guide cylinder is bolt, and the screw portion of bolt is hollow structure, institute
The bolt stated is threadedly coupled with upper cavity, and the guide rod top is located in the hollow part of screw rod；With the bolt of hollow structure
As guide cylinder, due to having screw thread on bolt, convenient for the connection of guide cylinder and upper cavity, threaded hole only need to be opened up on upper cavity
.
As a further improvement on the present invention, the lower part of the guide rod passes through head cover, and is mutually fixed with floating drum；Guide rod
It is fixed with floating drum, realizes the guiding role to floating drum so that floating drum can only move in the vertical direction, and cannot be in the horizontal direction
It is upper to overturn.
In conclusion the beneficial effects of the invention are as follows：Head cover is pushed to move up and down using the buoyancy of water, head cover moves upwards
It is contacted with upper cavity, is closed the opening of inner cavity, and the air in lower inner cavity is got into water surface rising in the process
It is discharged in inner cavity, head cover is made to be detached from upper cavity using the gravity of head cover itself when the water surface declines, the opening of inner cavity in opening, from
And water lines can not self-bleeding technological deficiency in the prior art for solution.
