Abstract
The utility model discloses an electric reversing valve, which comprises a protective cover and a motor, wherein a pressure gauge is arranged on the top of the protective cover; the motor is connected with an eccentric wheel through a speed reducing mechanism; the eccentric wheel is connected with one end of a connecting rod, the other end of the connecting rod is linked with a spring set, and the connecting rod penetrates through a two-station four-way valve; a sliding core rod is arranged in the two-station four-way valve; and a limit switch is arranged at a position where the eccentric wheel is located. The electric reversing valve has the advantages that after the motor is started through the speed reducing mechanism, the eccentric wheel drives the connecting rod to linearly reciprocate, and the tail end of the connecting rod is linked with the spring set, so that rapid push-pull action is produced in the two-station four-way valve, the connecting mode of each oil port of the two-station four-way valve is changed, and the aim of reversing liquid flow is fulfilled; and the eccentric wheel rotates to another dead point position, the limit switch is triggered, the limit switch sends a pulse signal to stop the operation of the motor, and a working process is finished.
Description
Technical field
The utility model relates to a kind of electronic selector valve.
Background technique
Electronic selector valve is applicable in the glycerine centralized lubrication system; The pressure grease of lubricant pump single line outlet is alternately seen off through main pipe; Electronic selector valve on the market exist reaction sensitive inadequately, open and close slowly, the shortcoming of action less reliable, and working life is short.For this reason, need to propose a kind of new technological scheme and solve the problems referred to above in fact for necessary.
The model utility content
In order to overcome the problem of above existence, the purpose of the utility model is to provide a kind of electronic rapidly selector valve that is quick on the draw, opens and closes.
The technological scheme that the utility model adopts is:
A kind of electronic selector valve comprises protective housing and motor, and said protective housing top is equipped with pressure gauge; Said motor is connected with eccentric wheel through reducing gear; Said eccentric wheel is connected with connecting rod one end, the said connecting rod the other end and cluster spring interlock, and said connecting rod passes two-position four-way valve; Be provided with sliding core bar in the said two-position four-way valve, said eccentric wheel place is equipped with limit switch.
Said reducing gear comprises worm gear and worm screw, and said worm gear and worm screw are meshing with each other.
Said protective housing comprises upper shell and lower shell body, and said upper and lower casing fastens through fastener.
The beneficial effect of the utility model is: motor is done straight reciprocating motion by the eccentric wheel drivening rod behind reducing gear, connecting rod end and cluster spring interlock; Make the push pull maneuver that produces in the two-position four-way valve rapidly, changed the connecting mode of each hydraulic fluid port of two-position four-way valve, reached the purpose of flow switching-over; This moment, the eccentric wheel rotation arrived another dead center position, had touched limit switch, and limit switch is seen pulse signal off; Stop the motor operation, accomplished a working procedure.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural representation of the utility model.
Wherein: 1, protective housing, 2, motor, 3, pressure gauge, 4, eccentric wheel, 5, worm gear, 6, worm screw, 7, connecting rod, 8, cluster spring, 9, two-position four-way valve, 10, sliding core bar, 11, limit switch, 12, upper shell, 13, lower shell body, 14, fastener.
Embodiment
