Brass discharge valve suitable for fresh milk machine
Technical Field
The invention relates to the technical field of fresh milk making machines, in particular to a brass exhaust valve suitable for a fresh milk making machine.
Background
A fresh milk machine, also called fresh milk machine, is a special device for making fresh milk products. Can meet the requirements of different consumers on fresh milk products. At present, the device lacks a discharge valve capable of effectively ensuring that fresh milk does not deteriorate.
Disclosure of Invention
In order to solve the problems, the invention discloses a brass drain valve suitable for a fresh milk machine.
The specific scheme is as follows:
the brass drain valve is characterized by comprising a brass drain valve main body, wherein the brass drain valve main body comprises a transversely arranged pipe cavity, the left end and the right end of the pipe cavity are respectively connected with quick-connection plugs, an air proportional valve, a milk way electromagnetic valve and a waterway electromagnetic valve are sequentially arranged at the top from left to right, a fresh milk pipeline is connected to the middle part of the front side of the brass drain valve, the air proportional valve, the milk way electromagnetic valve and the waterway electromagnetic valve are communicated with the pipe cavity, a duckbill one-way valve is arranged at the lower end of the air proportional valve, the milk way electromagnetic valve is an isolated milk inlet valve and used for controlling the on-off of the fresh milk pipeline, and the waterway electromagnetic valve is used for controlling the on-off of a pure water pipeline.
Further, the quick-connection plug at the left end of the brass exhaust valve main body is sequentially connected with the breast pump, the heating disc, the three-way electromagnetic valve and the liquid outlet nozzle, and the quick-connection plug at the right end is connected with the pure water pipeline through the flowmeter.
Further, the three-way electromagnetic valve comprises a milk inlet/water outlet, a milk outlet/water outlet and a waste liquid outlet, wherein the milk inlet/water outlet is connected with the heating plate, and the milk outlet/water outlet is connected with the liquid outlet.
The invention has the beneficial effects of ingenious structure, realization of milk foam production according to the needs of users, and effective prevention of deterioration of fresh milk in the pipeline, and can also ensure that no fresh milk remains in the pipeline.

Detailed Description
The present invention is further illustrated in the following drawings and detailed description, which are to be understood as being merely illustrative of the invention and not limiting the scope of the invention.
As shown in the figure, the invention provides a brass drain valve suitable for a fresh milk machine, which comprises a brass drain valve main body, wherein the brass drain valve main body comprises a transversely arranged pipe cavity, the left end and the right end of the pipe cavity are respectively connected with a quick-connection plug 1, an air proportional valve 2, a milk way electromagnetic valve 3 and a waterway electromagnetic valve 4 are sequentially arranged at the top from left to right, a fresh milk pipeline 5 is connected to the middle part of the front side, the air proportional valve 2, the milk way electromagnetic valve 3 and the waterway electromagnetic valve 4 are communicated with the pipe cavity, a duckbill one-way valve 6 is arranged at the lower end of the air proportional valve 2, the milk way electromagnetic valve 3 is an isolated milk inlet valve for controlling the on-off of the fresh milk pipeline 5, and the waterway electromagnetic valve 4 is used for controlling the on-off of a purified water pipeline 7.
In the embodiment, a quick-connection plug 1 at the left end of a brass drain valve main body is sequentially connected with a milk pump 8, a heating disc 9, a three-way electromagnetic valve 10 and a liquid outlet nozzle, and a quick-connection plug 1 at the right end is connected with a purified water pipeline 7 through a flowmeter 11.
In this embodiment, the three-way solenoid valve 10 includes a milk/water inlet, a milk/water outlet, and a waste liquid outlet, wherein the milk/water inlet is connected to the heating plate 9, and the milk/water outlet is connected to the liquid outlet 12.
The working principle of the application is as follows:
S1, starting a milk pump to generate negative pressure to open a milk path electromagnetic valve, sucking milk into a brass exhaust valve main body, and adjusting the opening and closing of an air proportional valve to adjust the air quantity;
s2, the milk foam enters a heating disc to be instantaneously heated, so that the quality of the milk foam is ensured;
S3, the heated milk foam enters the nipple through a three-way electromagnetic valve to finish milk foam discharging;
s4, the waterway electromagnetic valve is opened after milk foam is finished, fresh milk at the front section of the air valve is pushed into the milk tank through water pressure, so that the fresh milk is ensured not to deteriorate, and water is prevented from entering the milk tank through the flowmeter and the opening time of the milk channel electromagnetic valve, so that the fresh milk can be ensured to be in a refrigerating state all the time;
S5, after fresh milk is returned into the milk tank, the milk path electromagnetic valve is closed, the three-way electromagnetic valve is switched, water is discharged into the waste water pipe through the three-way electromagnetic valve through the milk pump and the heating disc, no fresh milk is ensured in the pipeline, and deterioration of the fresh milk in the pipeline can be prevented.
The technical means disclosed by the scheme of the invention is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
