Abstract
The utility model discloses a kind of centrifugal pump automatic exhaust device, belong to centrifugal pumping apparatus technical field.It includes centrifugal pump（1）, described centrifugal pump（1）Provided with centrifugal pump inlet（5）And outlet of centrifugal pump（4）, in centrifugal pump inlet（5）On be connected with feed pipe（6）, in outlet of centrifugal pump（4）On be connected with discharge nozzle（2）, in discharge nozzle（2）Close to outlet of centrifugal pump（4）Tube wall be provided with ball bead type check valve（3）, described ball bead type check valve（3）It is a normally opened check valve.The utility model can solve existing exhaust process need staff centrifugal pump is poured water manually exhaust, can not automated production.
Description
Technical field
The utility model belongs to centrifugal pumping apparatus technical field, and in particular to a kind of centrifugal pump automatic exhaust device.
Background technology
Centrifugal pump is to form vacuum after the hydraulic pressure in pump is gone out by impeller and intake.According to the structure and work of centrifugal pump
Make principle to understand, there is the most important condition that certain vacuum is water pump discharging water before water pump initial start-up, in water pump.If water
Do not reach vacuum in pump, not only water pump can not normal work, and can also badly damaged rotor center position accessory.So disleaf
Outside wheel under water centrifugal pump and self priming pump, before general each turn on pump all must into pump water-filling, be commonly called as plus diversion exhaust.Fill
Water method has two kinds：First, the water filling directly into pump, should now open air in air vent discharging pump；Second, gas in pump is taken out
Go, establish certain vacuum degree, water source is introduced and gone.But both approaches weak point is to need people's manual exhaust, not only time-consuming
Arduously, it is also inconvenient for automated production.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is to provide a kind of centrifugal pump and is vented dress automatically
Put, solve the problems, such as existing exhaust process need staff centrifugal pump is poured water manually exhaust, can not automated production.
To achieve the above object, the utility model uses following technical proposals：A kind of centrifugal pump automatic exhaust device, it is special
Sign is：Including centrifugal pump, described centrifugal pump is provided with centrifugal pump inlet and outlet of centrifugal pump, is connected with centrifugal pump inlet
Feed pipe, discharge nozzle is connected with outlet of centrifugal pump, ball bead type list is provided with tube wall of the discharge nozzle close to outlet of centrifugal pump
To valve, described ball bead type check valve is a normally opened check valve.
Compared with prior art, the utility model has following beneficial effects：Due to centrifugal pump discharge nozzle close to from
The tube wall of heart pump outlet is provided with a normally opened ball bead type check valve, and so when centrifugal pump intracavitary has air, air can be with
Smoothly discharged from ball bead type check valve, solve the problems, such as exhaust of manually wasting time and energy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1- centrifugal pumps, 2- discharge nozzles, 3- ball bead type check valves, 4- outlet of centrifugal pump, 5- centrifugal pump inlets, 6- enters
Expects pipe.
Embodiment
As shown in figure 1, a kind of centrifugal pump automatic exhaust device, including centrifugal pump, centrifugal pump be provided with centrifugal pump inlet and from
Heart pump export, feed pipe is connected with centrifugal pump inlet, discharge nozzle is connected with outlet of centrifugal pump, discharge nozzle close to from
The tube wall of heart pump outlet is provided with ball bead type check valve, and ball bead type check valve is a normally opened check valve.
Operation principle of the present utility model is：After being shut down when centrifugal pump is long on startup, can be had time in pump chamber and pipeline
Gas, cause the liquid in pipe can not be extracted into out of feed pipe in discharge nozzle, hoodle is installed on the discharge nozzle at outlet of centrifugal pump
After formula check valve, after centrifugal pump is opened, the air in pump chamber and pipeline is discharged from ball bead type check valve, after air is discharged,
After liquid enters discharge nozzle, under the impact force action of liquid, the hoodle of ball bead type check valve is upspring, and blocks exhaust outlet.
When not having pressure, hoodle is automatically fallen off, Exhaust Open, realizes the effect of exhaust.Therefore the utility model can realize centrifugation
Pump automatic ventilating function, automated production can be realized in production.
Claims (1)
