Abstract
The invention discloses an electric reversing valve comprising a protection cover and a motor. A pressure gauge is installed on the top of the protection 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 in linkage motion with a spring set, the connecting rod penetrates through a two-position four-way valve, a core sliding rod is arranged in the two-position four-way valve, and a limiting switch is installed on the position of the eccentric wheel. The electric reversing valve has the advantages that the eccentric wheel drives the connecting rod to do linear reciprocating motion after the motor is connected with the eccentric wheel through the speed reducing mechanism, the tail end of the connecting rod is in linkage motion with the spring set, rapid push-pull motions are enabled to be produced in the two-position four-way valve, the connecting methods of each oil port of the two-position four-way valve are changed, the liquid flow reversing purpose is achieved, right now the eccentric wheel rotates to another dead point position, the limiting switch is touched and sends out a pulse signal, the motor stops working, and a work process is finished.
Description
Technical field
The present invention relates to a kind of electric change valve.
Background technique
Electric change valve is applicable in the glycerine centralized lubrication system, the pressure grease of lubricant pump single line outlet is alternately seen off by main pipe, electric change valve on the market exists reaction sensitivity, the shortcoming not too reliably that opens and closes slowly, moves not, 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.
Summary of the invention
In order to overcome the problem of above existence, the object of the present invention is to provide a kind of electric change valve rapidly that is quick on the draw, opens and closes.
The technical solution used in the present invention is:
A kind of electric change valve, comprise protective housing and motor, described protective housing top is equipped with pressure gauge, described motor is connected with eccentric wheel by reducing gear, described eccentric wheel is connected with connecting rod one end, the described connecting rod the other end and cluster spring interlock, and described connecting rod passes two-position four-way valve, be provided with the slide core bar in described two-position four-way valve, described eccentric wheel place is equipped with limit switch.
Described reducing gear comprises worm gear and worm screw, and described worm gear and worm screw are intermeshing.
Described protective housing comprises upper shell and lower shell body, and described upper and lower casing fastens by fastener.
The invention has the beneficial effects as follows: motor is after reducing gear, do straight reciprocating motion by the eccentric wheel drivening rod, connecting rod end and cluster spring interlock make the push pull maneuver that produces in two-position four-way valve rapidly, have changed the connecting mode of each hydraulic fluid port of two-position four-way valve, reached the purpose of liquid stream commutation, this moment, the eccentric wheel rotation arrived another dead center position, had touched limit switch, and limit switch is sent pulse signal, stop the motor operation, completed a working procedure.
