Embodiment
Core purport of the present utility model is for providing a kind of solenoid directional control valve, and the working life of its coil is long.In addition, another core purport of the present utility model is for providing a kind of power takeoff that comprises the concrete mixer of above-mentioned solenoid directional control valve.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of a kind of embodiment of solenoid directional control valve provided by the utility model; Fig. 2 is a solenoid directional control valve A shown in Figure 1 place partial enlarged drawing.
A kind of solenoid directional control valve that the utility model provides comprises valve body 42 and spool 43, and the perisporium of the valve body 42 of solenoid directional control valve is provided with locking block 44, and locking block 44 can lock or the working position of the spool 43 of release solenoid directional control valve; The work of locking block 44 can be manual, also can be automatically, promptly manually or automatically lock or the position of release spool 43.
At first solenoid directional control valve is connected into work system, the electromagnetic coil energising of solenoid directional control valve produces electromagnetic force spool 43 is moved to the relevant work position, be communicated with the relevant work passage, this moment, the position of spool 43 can lock by locking block, during the system proper functioning, need not solenoid directional control valve is continued energising, spool 43 just can maintain this working position; When work system needs switch motion, solenoid directional control valve oppositely to be switched in short-term, the release locking block gets final product the locking of spool.
Solenoid directional control valve provided by the utility model, only need short time energising when system's switch motion, when proper functioning, can switch on constantly to solenoid directional control valve, 41 overwhelming majority times of electromagnetic coil of solenoid directional control valve inside are in the outage off position, thereby have reduced the loss of electromagnetic coil, prolonged the working life of electromagnetic coil 41, and reliable operation, energy saving reduces user cost.
In a kind of embodiment, locking block 44 connects the inwall of valve bodies 42 by diaphragm spring 45, and locking block 44 is protruding sphere near an end of spools 43, and the side face of spool 43 is provided with groove; When spool 43 was in the working position, locking block 44 was by the position of rabbeted lock fixed valve plug 43.
When locking block 44 is in running order, can be pressed in the groove of spool 43 by diaphragm spring 45, when solenoid directional control valve cuts off the power supply, because the existence of the impacting force of locking block 44, the axial force of 44 pairs of spools 43 of locking block is greater than the restoring force of spool 43, and spool 43 is maintained at the working position; When solenoid directional control valve was oppositely switched on, it is big that the restoring force of spool 43 becomes, and because of the surface of contact of locking block 44 and spool 43 is protruding sphere, locking block 44 can be compressed by spool 43 gradually and detach groove, thereby spool 43 move round about, this working state end.
