Description
Technical field
The present invention relates to a kind of solenoid valve, be specifically related to a kind of manually operated bi service electromagnetic valve of being with.
Background technique
Chinese patent CN2355189Y discloses a kind of hand and electric two-purpose solenoid valve, be used to control the break-make of fluid-transporting tubing, mainly form by valve body, valve pocket, electromagnetic valve core, manual spool, liquid entering hole and liquid outlet, in the valve pocket at liquid entering hole place, be provided with two passes, be provided with manual spool between two passes, in the two-way spool, a paths communicates with liquid outlet by manual spool, and another road communicates with liquid outlet by electromagnetic valve core after by manual spool again.Manually having pilot hole on the spool, the on off operating mode of manually controlling two paths by pilot hole comes the path of controlling liquid by passage, and to realize hand, the dual-purpose purpose of electricity, the more above-mentioned high efficiency and multi-function solenoid valve of its structure is simple, operates also more convenient.It is too complicated that the structural feature of this kind bi service electromagnetic valve remains, and all brought certain difficulty for manufacturing, installation, maintenance and use.
This kind bi service electromagnetic valve is when using manually-operable in addition, is to come the path of controlling liquid by passage by the on off operating mode that pilot hole is manually controlled two paths, is equal to solenoid valve is masked; When electric operating, need then to guarantee which the bar passage that communicates with electromagnetic valve core is unimpeded, not so, even even electromagnetic valve core is open-minded, this path is also blocked.Such consequence is that before using solenoid valve, past contact needs adversary's movable valve plug to verify, and can normally carry out to guarantee electronic unblank bi service electromagnetic valve valve, has brought very big inconvenience to use.
Summary of the invention
The purpose of this invention is to provide and a kind ofly simple in structure, easy to process both can adopt manual unblank and rely on electromagnetic attraction to keep normal open state, also can adopt the electromagnetism unblank and rely on electromagnetic attraction and the bi service electromagnetic valve that keeps normal open state and need not before electronic unblank, path to be verified.
The technological scheme that realizes the object of the invention is: a kind of bi service electromagnetic valve, have valve body, and by valve pocket, inlet passage and the outlet passage that valve body surrounded, be arranged on valve seat, spool, spring, moving iron core, winding, fixed core in the valve pocket, and push rod; Described valve pocket, inlet passage and outlet passage communicate, and described spring is between described spool and described fixed core and be set on the described push rod, and described winding is around described fixed core setting; One end of described push rod stretches out valve pocket and exposes outside the valve pocket, and the other end of described push rod stretches in the valve pocket and with described moving iron core fixedlys connected.
Described winding is one or two, and is arranged in the described valve pocket around fixed core.
Described valve seat is arranged on the middle part of valve pocket, and between outlet passage and inlet passage; Described spool is fixedly installed on the middle part of described push rod, and its shape matches with described valve seat; Described winding and fixed core are arranged on the other end away from described push rod of valve pocket.
The corresponding end of described spool and described valve seat is arranged with sealing rubber cover.
Described valve pocket runs through described valve body, and the side near push rod of valve body is provided with threaded joints, stuffing box gland and sealing nut; Another side is provided with threaded joints, seal washer and sealing nut.Also be set with sensitive switch on the described valve body, described exposing on the outer part push rod of valve pocket is set with trigger component, and described trigger component can move along with moving of push rod and described sensitive switch is triggered.
The present invention has positive effect:
(1) because the present invention adopts the structural design with " end of described push rod stretches out valve pocket and exposes outside the valve pocket; the other end of described push rod stretches in the valve pocket and with described moving iron core fixedlys connected ", with respect to hand and electric two-purpose solenoid valve of the prior art, can simplify the structure of bi service electromagnetic valve greatly, all bring in various degree facility for manufacturing, installation, maintenance and use, need not simultaneously before electronic unblank, path to be verified.
(2) the present invention can adopt the structural design of having only a winding; When adopting a winding and high voltage power connection, its effect can provide a bigger adsorption force, even push rod is not manually pressed, the magnetic force that described winding produces also can make moving iron core be attracted on the described fixed core, keep the solenoid valve normal open state, make both manually unblanks of the present invention, also can electronic unblank.
(3) the present invention also can adopt the structural design of using two windings; When adopting two windings, two windings can be connected with low voltage power supply and high voltage power supply respectively, so just can so that the present invention under the effect of high voltage power supply, one of them winding can provide big adsorption force to realize automatic electronic unblank, can also be making another winding that a less adsorption force is provided under the effect with the low voltage power supply again after the unblank, to keep normal open state.
(4) valve pocket among the present invention runs through described valve body, and the side near push rod of valve body is provided with threaded joints, stuffing box gland and sealing nut; Another side is provided with threaded joints, seal washer and sealing nut, and such structural design has the better seal performance.
(5) the corresponding end of spool among the present invention and described valve seat is arranged with sealing rubber cover, makes spool like this when the described valve seat of sealing, can have better seal, reduces the processing request to spool and valve seat simultaneously.
(6) also can be set with sensitive switch on the described valve body of the present invention, described exposing on the outer part push rod of valve pocket is set with trigger component, described trigger component can move along with moving of push rod and described sensitive switch is triggered, can guarantee like this time by lower push-rod, drive trigger component and trigger sensitive switch, to control other components and parts work.
