Abstract
The utility model provides an automatic controlled three-way valve, which comprises a valve body, a valve core, and a rotary device of the valve core. The utility model is characterized in that the rotary device of the valve core is a stepping motor, wherein, a rotating shaft of which is directly connected with the back part of the valve core and the input end of which is connected with a control circuit. When the control circuit separately gives different signals to the stepping motor, the stepping motor drives the valve core to change the channel direction of the valve core. The circumferential side surface of the valve core is provided with a convex block. The circumferential inner surface of the valve body is provided with a convex ring which is provided with a notch which can cause the convex block of the valve core to be embedded into the notch and to rotate a certain angle. The back part of the valve body is connected with a positioning annular valve body of the valve core through threads on the inner ring surface, and a valve core positioning ring is arranged between the positioning annular valve body of the valve core and an annular convex on the circumference of the back part of the valve core. The utility model has the advantages of reasonable structure, and convenient and reliable control. The resource waste and the safety hazard caused by the misoperation of the three-way valve can be eliminated.
Description
Technical field
The utility model belongs to a kind of valve, is a kind of automatic control three-way valve specifically.
Background technique
Existing three-way valve mainly comprises valve body, spool and knob.Drive spool by artificial turning knob, make the channel change direction on the spool, make passage respectively with valve body on different channel direction UNICOM, thereby change the flow direction of gas (or liquid).Its shortcoming is: owing to will change the flow direction of gas (or liquid) by the direct hands-on valve knob of people, use very inconvenient.As be used in the ozonizer pipeline of utensils such as kitchen guarding's apparatus, disinfection cabinet and dryer, when forgetting conversion, might cause the wasting of resources or can produce potential safety hazard.
Summary of the invention
The purpose of this utility model is the shortcoming and defect at prior art, and a kind of automatic control three-way valve is provided.Rational in infrastructure, control is convenient, reliable, can eliminate the wasting of resources and potential safety hazard that the three-way valve misoperation causes.
The technological scheme that the utility model is taked is: a kind of automatic control three-way valve, comprise valve body, spool, valve core rotation device, it is characterized in that described valve core rotation device is a stepper motor, the stepper motor rotating shaft directly is connected with the spool rear portion, and the input end of stepper motor is connected with control circuit.Give the different signal of stepper motor respectively when control circuit, make stepper motor drive spool and change its channel direction.
Described spool circumference is provided with projection on the side, and valve body circumference inner face is provided with bulge loop, and bulge loop has the spool projection is embedded wherein and the notch that turns an angle.
Described valve body rear portion is provided with a spool positioning ring by the spool location ring-type valve body that is threaded on the inner ring surface between the cyclic convex edge around spool location ring-type valve body and the core rear portion.
Described stepper motor is inserted in the rotary shaft hole identical with the rotating shaft shape on the open tubular column that stretches out in the middle of the spool rear portion by the cylinder-shaped shaft that has breach and is connected with spool, and the fastening foot that fastening foot that described stepper motor side wall of outer shell stretches out and body wall stretch out connects as one by screw.
The utility model compared with prior art has many advantages and good effect:
1, controls the conducting direction of the gas (or liquid) of three-way valve by stepper motor automatically, increase work efficiency, reduce labor intensity;
2, control the conducting direction of the gas (or liquid) of three-way valve automatically, reduced the unnecessary wasting of resources;
3, control the conducting direction of the gas (or liquid) of three-way valve automatically, guarantee to use reliable, safety.
