Abstract
A solenoid valve with a self-diagnosis function comprises an electromagnetic coil, an end plate, a spring seat, a valve core, a push rod, a spring and a push rod seal, wherein the spring is arranged on the spring seat; the valve seat is provided with a valve core and a flow passage, the valve core is provided with an annular groove communicated with the flow passage on the valve seat, and the outer end of the electromagnetic coil is provided with two groups of totally-enclosed integrated photoelectric switches. The utility model has simple structure; the photoelectric switch is a totally-enclosed integrated type, so that the photoelectric switch is moisture-proof, corrosion-resistant, good in reliability and long in service life; the manufacture is easy; the state of the valve core can be effectively monitored.
Description
Technical field
The utility model relates to the valve that a kind of hydraulic system is used, and especially relates to the solenoid valve that a kind of hydraulic system is used.
Background technique
Along with the digitizing in mine is unmanned, the state-detection and the fault diagnosis of the large-scale unmanned winning equipment in down-hole are more and more important, and in the hydraulic system, the malfunctioning fault of the jam of solenoid valve is more common again, at present, when this class solenoid valve breaks down, can only rely on operator to judge, check, handle.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that existing solenoid valve exists, and provides a kind of structure to have the solenoid valve of self diagnosis fault function.
The purpose of this utility model is achieved through the following technical solutions: it comprises electromagnetic coil, end plate, spring seat, valve seat, spool, push rod, spring, push rod seal, and spring is housed on the spring seat; Spool is housed on the valve seat and is provided with runner, spool is provided with the circular groove that is communicated with runner on the valve seat, and two groups of totally-enclosed integrating optical electric switches are housed in the electromagnetic coil outer end.
Described optoelectronic switch can be correlation, and illuminator and photoreceptor centering arrange, also can be reflective, illuminator and photoreceptor homonymy layout.
The utility model is simple in structure; Described optoelectronic switch is totally-enclosed integrated switched, thereby moistureproof, corrosion-resistant, good reliability, long service life; Easy to manufacture; Can effectively monitor the spool state.
Description of drawings
Fig. 1 (a) and (b), (c) are in the structural representation of meta (P position), A position, B position respectively for the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment comprises electromagnetic coil 1, end plate 2, spring seat 3, valve seat 4, spool 5, push rod 6, spring 7, push rod seal 8, and spring 7 is housed on the spring seat 3; Spool 5 is housed on the valve seat 4 and is provided with runner, spool 5 is provided with the circular groove that is communicated with runner on the valve seat 4, and two groups of totally-enclosed integrating optical electric switches, promptly inboard optoelectronic switch 9 and outside optoelectronic switch 10 are housed in electromagnetic coil 1 outer end.
Fig. 1 (a) and (b), (c) are in the configuration state schematic representation of meta (P position), A position, B position respectively for the utility model one embodiment; Along with the difference of spool 5 positions, the coupled condition of P, A, B is also different, thereby plays runner switching effect, and when electromagnetic coil 1 no electric circuit, the spring 7 that is loaded on the spring seat 3 resets spool 5; During work, if the electromagnetic coil on right side energising, spool 5 is moved to the left under the push rod effect of left side, solenoid valve is in the B position, right side optoelectronic switch 9 and optoelectronic switch 10 equal conductings, after the electromagnetic coil dead electricity, reset at spring force effect lower valve core 5, the two groups of optoelectronic switches 9 in right side and optoelectronic switch 10 all not conductings are moved to the left and can not put in place if action the time blocks spool 5, and then optoelectronic switch 9 can't conducting, judge the right side action failure, if spool 5 is moved right by card to put in place during the power-off restoration of right side, then optoelectronic switch 10 can't cut out, and judges the right side fault that resets.Two groups of optoelectronic switch working principles in left side are also like this with diagnosis mechanism.
For the solenoid valve that has only two working positions, structure also is consistent with working mechanism.
Described optoelectronic switch is a correlation, and illuminator and photoreceptor centering are arranged; Also can be reflectively, illuminator and photoreceptor homonymy are arranged.
Claims (3)
1, a kind of solenoid valve with self-diagnostic function comprises electromagnetic coil, end plate, spring seat, valve seat, spool, push rod, spring, push rod seal, and spring is housed on the spring seat; Spool is housed on the valve seat and is provided with runner, spool is provided with the circular groove that is communicated with runner on the valve seat, it is characterized in that, two groups of totally-enclosed integrating optical electric switches are housed in the electromagnetic coil outer end.
