Liquid rotary pump idle running.Install that air extractor is at high cost in CIP cleaning solution holding vessel, although and the method can gas in drain tank
Body, but material pipe or these positions of filling head inevitably have gas entrance, and liquid rotary pump is be easy to cause to generate during operation
Overcompression phenomenon.
Utility model content
The purpose of this utility model is to provide generate overcompression and vacuum degree deficiency when a kind of solution pendular ring pump operation
The liquid rotary pump that can stablize air pressure inside of disadvantage.
Technical solution adopted in the utility model is：
A kind of liquid rotary pump that can stablize air pressure inside, the outlet including shell, the inlet pipeline of connection shell, connection shell
Pipeline is in the intracorporal impeller of shell and motor, and the rotation center of the output shaft insertion impeller of motor, shell is in connection inlet tube
The side in road is equipped with check valve.
As an improvement of the above scheme, check valve includes valve body, floating ball and top cover, and top cover is located at the upper end of valve body, top cover
With gas outlet, the lower end of valve body is connected to shell, and valve inner shrinks funnel and is used for support floating ball.
It as an improvement of the above scheme, is removably to be threadedly coupled between top cover and valve body.
As an improvement of the above scheme, shell includes first shell and second shell, between first shell and second shell
By flanged joint, first shell is connected to inlet pipeline, and check valve is arranged on the first shell, and second shell is connected to export
Pipeline, impeller are in the inside of second shell.
As an improvement of the above scheme, first shell is infundibulate, and second shell is cylindrical shape.
It as an improvement of the above scheme, is to be threadedly coupled between check valve and shell.
It as an improvement of the above scheme, is welding between check valve and shell.
The beneficial effects of the utility model：When the pressure needed for the inlet pipeline air pressure of liquid rotary pump is connected lower than check valve,
Check valve is failure to actuate；When the inlet pipeline air pressure of liquid rotary pump increases, check valve is opened, while the gas in liquid is through check valve
It is discharged to the external world, check valve is closed again after the air pressure of inlet pipeline reduces；The supplement of check valve is not only simple in structure, Er Qieneng
Air pressure at enough stable inlet pipeline, overcompression and vacuum degree deficiency when avoiding pendular ring pump operation.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing：
Fig. 1 is the cross-sectional view of liquid rotary pump；
Fig. 2 is the perspective view of liquid rotary pump；
Fig. 3 is the perspective view of check valve；
Fig. 4 is the cross-sectional view of check valve.
Specific embodiment
Referring to Figures 1 and 2, the utility model is a kind of liquid rotary pump that can stablize air pressure inside, including shell, connection shell
