Description
Technical field
The utility model is related to current break-make control assembly, specifically a kind of water cut-off pump pump head.
Background technology
Domestic water purification machine system is commonly equipped with water cut-off pump and is controlled come the break-make to water route, the pump head body structure of water cut-off pump
Cut off the water supply into sealing of cutting off the water supply, in pump head body provided with control and seal the disconnected water film bearing of keying.When existing water cut-off pump is applied, break water film bearing
Sealing of cutting off the water supply can frequently and be promptly sealed, so that significant shock occurs in water cut-off pump, this has had a strong impact on pushing away for water cut-off pump
Wide application.
Utility model content
The purpose of this utility model is to solve existing water cut-off pump easily to be occurred frequently and promptly sealing cutting off the water supply in application
It can exempt or reduce vibrations when applying there is provided a kind of water cut-off pump pump head the problem of sealing.
The purpose of this utility model is achieved through the following technical solutions:A kind of water cut-off pump pump head, including with water inlet
The pump head body of chamber and booster cavity, pump head body, which is constituted, the water inlet and the delivery port for connecting booster cavity, pump head body for connecting intake antrum
Constitute to cut off the water supply provided with control in sealing of cutting off the water supply, pump head body on booster cavity and the passage of delivery port connection and seal cutting off the water supply for break-make
Component, the intake antrum includes connecting the intake antrum one being sequentially arranged on passage, intake antrum two by water inlet to booster cavity and entered
Water cavity three, the pump head body movable sealing is connected with the component that dams, the component that dams provided with inlet through hole one, intake antrum one with
Intake antrum two is connected by inlet through hole one, and pump head body, which is constituted, the head piece that dams, and water inlet passes through the head piece that dams with intake antrum one
Connect, the component that dams dams head piece with entering for control under hydraulic pressure collective effect in the hydraulic pressure in intake antrum one and intake antrum two
The control water assembly of runner size between water through hole one, and the contact area of dam component and intake antrum two is more than itself and intake antrum one
Contact area;The component of cutting off the water supply is hydraulic pressure, hydraulic pressure and delivery port and sealing of cutting off the water supply in intake antrum two in booster cavity
Between in-channel water pressure collective effect under control cut off the water supply the component changed under break-make two states of sealing.
When water cut-off pump described in the utility model is not actuated, sealing of cutting off the water supply is off shape in the presence of component of cutting off the water supply
State, when starting the utility model, supercharging cavity pressure increase, cut off the water supply component in booster cavity hydraulic pressure, hydraulic pressure in intake antrum two,
And booster cavity and delivery port are connected in control sealing of cutting off the water supply under the collective effect of in-channel water pressure between delivery port and sealing of cutting off the water supply,
So that the utility model can rapidly normal water flowing.Now, component is dammed in both intake antrum one and intake antrum two hydraulic pressure
Effect is lower to be moved to the direction away from the head piece that dams, and the runner between head piece and inlet through hole one that dams becomes big, into intake antrum
Current increase in two, intake antrum two is also pressurized therewith, and because damming, component is more than by intake antrum by the active area of intake antrum two
One active area, when intake antrum two is pressurized to certain hydraulic pressure, the component that dams is in both intake antrum one and intake antrum two hydraulic pressure
In the presence of can be moved to the direction close to the head piece that dams, the runner between head piece and inlet through hole one that dams diminishes.This practicality is new
Type is in the presence of the component that dams, and the runner between head piece and inlet through hole one that dams becomes repeatedly to diminish greatly, with continuing for current
Discharge, intake antrum two will not build the pressure, and may be such that hydraulic pressure convergence zero-pressure in intake antrum two, therefore, component of cutting off the water supply is to sealing of cutting off the water supply
Slap dynamics can be weakened, and vibrations nature reduces.
Further, the component that dams includes dam packing and the block piece that dams, dam block piece and the pump head body activity
It is tightly connected, inlet through hole one, which is arranged at, dams on block piece, dams to constitute to have between block piece and pump head body and connect extraneous air
Chamber, the packing that dams, which is fixed on, to dam on block piece and just the head piece that dams is being set.
Further, the pump head body constitutes the detent for having annular, and the head piece that dams is arranged on detent ring
Around region in, the block piece that dams is barrel-shaped structure, and the packing that dams is fixed on the sealing end for the block piece that dams, and dam block piece
In openend insertion detent, and seal is equipped between the outboard sidewalls and detent inwall of the block piece that dams;The sky
Air cavity is located at the region below seal including gap between block piece and detent of damming.The utility model passes through in the block piece that dams
Outboard sidewalls and detent inwall between seal is set so that dam block piece displacement when also can guarantee that dam block piece and pump
Sealing property between head body, you can reach the effect of movable sealing connection.
Further, the pump head body is sealedly connected with gland, and the component of cutting off the water supply includes helping envelope spring and disconnected water film bearing,
The disconnected water film bearing peripheral sealing is fixed between pump head body and gland, and disconnected water film bearing is just constituted to the end face that gland is set and intake
The partial sidewalls of chamber two, the other end of disconnected water film bearing is just set to sealing of cutting off the water supply, and disconnected end of the water film bearing just to sealing of cutting off the water supply
Face constitutes the partial sidewalls of booster cavity;It is described to help envelope spring in intake antrum two, and its two ends is respectively acting on disconnected water film bearing
And gland.In this way, component of the present utility model of cutting off the water supply also is helped the effect of envelope spring come the sealing that controls to cut off the water supply in two kinds of break-make by it
Changed under state, when water cut-off pump described in the utility model is not actuated, disconnected water film bearing is close to cut off the water supply in the presence of envelope spring is helped
Sealing, sealing property during ensuring that the utility model is not used.
In summary, the utility model has the advantages that:The utility model is in output hydraulic pressure less than input raw water
Under water pressure condition, cut off the water supply component hydraulic pressure, passage between hydraulic pressure and delivery port and sealing of cutting off the water supply in intake antrum two in booster cavity
Under the collective effect of interior hydraulic pressure to sealing cut off the water supply sealing direction move, now, because of the adjustment effect for the component that dams, intake antrum two
Interior hydraulic pressure also convergence zero-pressure, in this way, the utility model can reduce cut off the water supply slap power of the component to pump head body, Jin Erke when applying
To exempt or reduce vibrations.
