Abstract
The invention relates to an electromagnetic reversing valve, which comprises a valve body, a first electromagnet set and a second electromagnet set, wherein the valve body is provided with a valve core and a spring; both the first electromagnet set and the second electromagnet set comprise two electromagnets; a sliding valve and a travel switch are also arranged in the valve body; the sliding valve is provided with a contact; and the two ends of the sliding valve are connected with the first electromagnet set and the second electromagnet set through a first pipeline and a second pipeline respectively. The electromagnetic reversing valve has the advantages of simple structure, high automation degree, capabilities of emitting a signal through a pressure-operated valve, controlling the electromagnetic reversing valve to realize alternate oil supply and opening of two oil supply pipelines and buffering reversing through design of the spring and strong electromagnets, high safety and capability of prolonging the service life of the electromagnetic reversing valve.
Description
Technical field
The present invention relates to a kind of solenoid directional control valve in the mechanical field application.
Background technique
Solenoid valve is the industry equipment with Electromagnetic Control, is used in direction, flow, speed and other the parameter of adjusting medium in the industrial control system, but if directly commutation in the practical application, can be to the solenoid valve injury.
Summary of the invention
In order to overcome defects, the invention provides a kind of solenoid directional control valve, send signal by pressure-operated valve, the control solenoid valve is realized alternately fuel feeding and the opening of two oil supply pipelines.
The technical solution adopted for the present invention to solve the technical problems is: a kind of solenoid directional control valve, comprise valve body, valve body is provided with spool and spring, also comprise the first electromagnet group and the second electromagnet group, the first electromagnet group and the second electromagnet group include two blocks of electromagnet, valve body is provided with guiding valve and position limit switch in also, and guiding valve is provided with contact, and the guiding valve two ends are connected to the first electromagnet group and the second electromagnet group by the first pipeline and second pipe respectively.
The invention has the beneficial effects as follows: simple in structure, automaticity is high, sends signal by pressure-operated valve, and the control solenoid directional control valve is realized alternately fuel feeding and the opening of two oil supply pipelines; The design of spring and powerful electromagents is cushioned so that commutate, and is safe, also prolongs the working life of solenoid directional control valve.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is contact and position limit switch closed state figure.
Among the figure: 1, valve body; 2, spool; 3, spring; 4, the first electromagnet group; 5, the second electromagnet group; 6, guiding valve; 7, position limit switch; 8, contact; 9, the first pipeline; 10, second pipe; 11, the first entrance; 12, second pipe entrance.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments: such as Fig. 1 to a kind of solenoid directional control valve shown in Figure 2, comprise valve body 1, valve body 1 is provided with spool 2 and spring 3, also comprise the first electromagnet group 4 and the second electromagnet group 5, the first electromagnet group 4 and the second electromagnet group 5 include two blocks of electromagnet, adopt powerful electromagents and spring, so that commutation is cushioned, commutation is reliable, valve body 1 is provided with guiding valve 6 and position limit switch 7 in going back, guiding valve 6 is provided with contact 8, and guiding valve 6 two ends are connected to the first electromagnet group 4 and the second electromagnet group 5 by the first pipeline 9 and second pipe 10 respectively.
When lubricant pump starts, the first electromagnet group 4 gets electric, the lubricating grease of lubricant pump output is in the first entrance 11 is sent to the first pipeline 9, in the first pipeline 9 and second pipe 10, be equipped with pressure-operated valve, when pressure that the first pipeline 9 terminal pressure Overpressure of a safety valve control valves are set, push guiding valve 6 to right side, when guiding valve 6 is pushed the right side to and the contact 8 of its interlock pushed the left side, be in on-state with position limit switch 7, send signal to electric control cubicle, make 4 outages of the first electromagnet group, lubricant pump quits work, return to original state, during next oil supply, 5 energisings of the second electromagnet group, the lubricating grease of lubricant pump output is sent to second pipe 10 through second pipe entrance 12, the pressure-operated valve action is so that contact 8 and position limit switch 7 are in off state.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
