Abstract

The utility model discloses special-shaped normally closed two-port valve, including valve body, spool and the first solenoid and the second solenoid；By arranging charging aperture on valve body, filtering liquid outlet and solid mixture outlet, and supporting spool arranges solid mixture clear opening, filtrate is designed by the passage such as hole, filter tank, solenoid is coordinated to drive spool to move in valve body, on the basis of break-make, develop solid tunnel and fluid passage, thus realize solid-liquid separation.

Description

The normally closed two-port valve of abnormity

Technical field

This utility model relates to electromagnetic valve, particularly relates to special-shaped normally closed two-port valve.

Background technology

Traditional electromagnetic valve only has single conducting and cutoff function, it is impossible to real on the basis of conducting and cutoff function Showing solid-liquid separation, this just significantly limit the application of electromagnetic valve, and horn of plenty electromagnetic valve is in the application of other field, it would be highly desirable to occurs New electromagnetic valve changes this present situation.

Summary of the invention

For solving above-mentioned technical problem, the purpose of this utility model is to provide and a kind of can realize the abnormity of solid-liquid separation often Close two-port valve.

The technical solution adopted in the utility model is:

Special-shaped normally closed two-port valve, including valve body, spool and the first solenoid and the second solenoid；

This valve inner has one and extends transversely through the valve insertion of valve body both sides to accommodate spool, and valve body top have into Material mouth, body base has filtration liquid outlet and the solid mixture outlet of communicating valve inner chamber, and this filtration liquid outlet is used for Connecting wastewater discharge pipe, solid mixture outlet is discharging opening；

The embedded armature that is cased with of described spool, spool one end is corresponding with the first solenoid and spring is provided therebetween, The spool other end is corresponding with the second solenoid and spring is provided therebetween；

Described spool is additionally provided with solid mixture clear opening, filtrate is led directly to by hole, filter tank, this solid mixture Hole is used for connecting charging aperture and discharging opening, and filtrate is used for connecting filter tank and filtering liquid outlet, in this filter tank by hole It is provided with drainage screen and for connecting charging aperture.

The beneficial effects of the utility model:

The normally closed two-port valve of abnormal shape of the present utility model mixes by arranging charging aperture, filtration liquid outlet and solid on valve body Close material outlet, and supporting spool arranges solid mixture clear opening, filtrate is designed by the passage such as hole, filter tank, joins Closing solenoid drives spool to move in valve body, develops solid tunnel and fluid passage, thus realize on the basis of break-make Solid-liquid separation.

Detailed description of the invention

As it is shown in figure 1, be the normally closed two-port valve of abnormal shape of the present utility model, including valve body 331, spool 332 and the first electricity Magnetic coil 333 and the second solenoid 334；

This valve body 331 is internal to be had one and extends transversely through the valve insertion of valve body 331 both sides to accommodate spool 332, and valve body 331 Top has the charging aperture 3311 of communicating valve inner chamber, has filtration liquid outlet 3312 He of communicating valve inner chamber bottom valve body 331 Solid mixture outlet 3313, this filtration liquid outlet 3312 is used for connecting wastewater discharge pipe, and solid mixture outlet 3313 is Described discharging opening；

As in figure 2 it is shown, the embedded armature 3321 that is cased with of described spool 332, spool 332 one end is right with the first solenoid 333 And spring 335 should be provided therebetween, spool 332 other end is corresponding with the second solenoid 334 and is provided therebetween Spring 335, when master control system is energized to the first solenoid 333 and the second solenoid 334, just can spool 332 at valve body 331 Inside move horizontally and connect concrete passage, just can restPose under the effect of spring 335 during power-off, thus constitute spool The dynamical system of 332；

Described spool 332 is additionally provided with solid mixture clear opening 3322, filtrate passes through hole 3323, filter tank 3324, This solid mixture clear opening 3322 is used for connecting charging aperture 3311 and discharging opening, and filtrate is used for connecting filtration by hole 3323 Groove 3324 and filtration liquid outlet 3312, be provided with drainage screen 3325 and for connecting charging aperture 3311 in this filter tank 3324, This part describes the pipe-line system of main presentation spool 332.

Of the present utility model one of them application is described below, and as a example by washing rice, meter Rong is washed in the configuration of special-shaped normally closed two-port valve During device, washing a meter container outlet connection charging aperture 3311, need individually to discharge washed rice, this process is divided into following three kinds of shapes State:

(1) during power-off, for the original state of special-shaped normally closed two-port valve 33, as it is shown in figure 5, charging aperture 3311 is by spool 332 Block；The most also as washing a meter state.After tank Nei Jia meter is intake again, rice is washed in supersonic generator work.

(2) washing rice when completing waste discharge, the first solenoid 333 powers on, and produces electromagnetic attraction by spool 332 toward left side It is pulled through a segment distance so that charging aperture 3311, filter tank 3324, filtrate are by hole 3323, filtration liquid outlet 3312 successively Connection, due to the existence of drainage screen 3325, only washes the waste water during rice and can discharge, and rice material is retained in rice bucket 2；Waste discharge Appropriate moisture (water rice mixture) in washing meter tank 31 can be retained, it is possible to only retain cleaned rice material after water process.

(3), during discharge, as it is shown in figure 5, the first solenoid 333 power-off, the second solenoid 334 powers on, spool 332 warp Cross original state further to move to right so that charging aperture 3311, solid mixture clear opening 3322, discharging opening are sequentially communicated, water Rice mixture is expelled directly out, or first clears washed rice material, is then exhausted from moisture.

Drive it should be noted that spool of the present utility model is not limited only to solenoid, be only used as preferred embodiment, also Mechanism such as common known drive such as other drive mechanism, such as micromachine, minitype cylinder etc. can be used.

The foregoing is only preferred embodiments of the present utility model, this utility model is not limited to above-mentioned embodiment party Formula, if with essentially identical means realize the technical scheme of this utility model purpose broadly fall into protection domain of the present utility model it In.
