Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of large flow electromagnetic water route stop valve.
Background technology
Existing normally closed type water route stop valve, when after solenoid energising, produces electromagnetic attracting force iron core,Iron core drives Rubber end to move upward simultaneously, opens diaphragm center hole. Under Water Pressure, jack-up barrier film,Current are flow through from valve body center-aisle, directly flow out from delivery port; Having in addition sub-fraction current is from barrier filmAperture flows to barrier film upper chamber, flows out, then flow to delivery port from center-aisle from diaphragm center hole. Work as waterRoad pressure is very little or while thering is no pressure, barrier film can not be risen by jack-up, causes discharge very little. Common barrier filmThe Chinese utility model patent that formula stop valve operation principle can be CN88200739U referring to publication number.
Summary of the invention
For the defect existing in prior art, the purpose of this utility model is to provide one not to be subject to waterRoad pressure influence, can maintain the large flow electromagnetic water route stop valve of max water yield always.
For reaching above object, the utility model adopts following technical scheme.
A kind of large flow electromagnetic water route stop valve, comprising: valve body, barrier film, iron core, solenoid andSpring, described valve body is made up of intake tunnel, exhalant canal and valve pocket, and described barrier film is arranged in valve pocket and usesIntake tunnel mouth, exhalant canal are cut off, on barrier film, be provided with the barrier film aperture corresponding with intake tunnel andThe diaphragm center hole corresponding with exhalant canal, one end of described iron core is provided with corresponding with diaphragm center hole closeBlocking, the other end of iron core is connected with valve body by spring, and described solenoid is centered around around iron core; ItsBe characterised in that, be also provided with linkage support on barrier film, described sealing-plug is through linkage support reciprocal with iron coreMove and block diaphragm center hole or mention barrier film.
As further illustrating of such scheme, in linkage support, be provided with through hole, in one end of iron coreBe provided with the connecting rod through through hole, described sealing-plug is arranged on connecting rod and can not from through hole, passes
As further illustrating of such scheme, the Breadth Maximum of described sealing-plug is greater than the maximum of through holeWidth.
As further illustrating of such scheme, between barrier film and valve body, be provided with back-moving spring, multiplePosition spring is in the time of natural extended configuration, and barrier film just in time cuts off intake tunnel and exhalant canal.
As further illustrating of such scheme, described sealing-plug is Rubber end.
Compared with prior art, the beneficial effects of the utility model are: by linkage support is set, carryGo out a kind of novel water route stop valve structure, when iron core moves up, drive barrier film to move upward, separateCertainly the very little problem of discharge in the time that water route pressure is very little or there is no pressure, ensures to have all the time considerable currentAmount.

Detailed description of the invention
Understand better essence of the present utility model for convenience of those skilled in the art, below in conjunction with accompanying drawingDetailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, a kind of large flow electromagnetic water route stop valve, comprising: valve body 1, barrier film 2, iron core3, solenoid 4 and spring 5. Wherein, described valve body 1 is by intake tunnel 1-1, exhalant canal 1-2 and valve pocket 1-3Composition, described barrier film 2 is arranged in valve pocket 1-3 and is used for intake tunnel 1-1 and exhalant canal 1-2 to cut off. EveryFilm 2 is provided with the barrier film aperture 2-1 corresponding with intake tunnel 1-1 and the diaphragm center corresponding with exhalant canal 1-2Hole 2-2. The sealing-plug 7 corresponding with diaphragm center hole 2-2, the other end of iron core 3 are installed in one end of iron core 3Be connected with valve pocket 1-3 by spring 5, described solenoid 4 is centered around around iron core 3, solenoid 4 power on/offTime, can realize the reciprocating motion of iron core 3; It is characterized in that, on barrier film 2, be also provided with linkage support 6, instituteStating sealing-plug 7 moves back and forth and blocks diaphragm center hole 2-2 or mention barrier film through linkage support 6 and with iron core 32。
Wherein, in linkage support 6, be provided with through hole, be provided with the connecting rod 8 through through hole in one end of iron core 3,Described sealing-plug 7 is arranged on connecting rod 8 and can not from through hole, passes. In the present embodiment, preferably through hole is circleShape hole, preferred rubber head is the socket cap that diameter is greater than through-hole diameter. In other embodiments, will sealThe Breadth Maximum that the Breadth Maximum of plug is arranged to be greater than through hole also can, be not limited to the present embodiment.
Further, after solenoid power-off for ease of realizing the reset of barrier film, at barrier film 2 and valve bodyBetween 1, be provided with back-moving spring 9, at back-moving spring 9, during in natural extended configuration, barrier film 2 just in time will be intake logicalRoad 1-1 and exhalant canal 1-2 cut off.
Specific works principle is: when solenoid 4 is not switched on, iron core 3 is at spring 5 and back-moving spring 9Under drive, move downward, make Rubber end block diaphragm center hole 2-2. After water flowing, in the short time current constantly fromBarrier film aperture 2-1 flows in barrier film 2 upper chamber, causes barrier film 2 upper pressure to increase gradually, promotes barrier film 2Move down, until barrier film 2 cuts off intake tunnel 1-1 and exhalant canal 1-2, current cut-off, cuts thereby playThe effect of sealing stream. After solenoid 4 energisings, produce electromagnetic attracting force iron core 3, iron core 3 drives rubber simultaneouslyHead moves upward, and opens diaphragm center hole 2-2, opens rear iron core 3 and pulls barrier film 2 upwards to transport by linkage support 6Moving. Intake tunnel 1-1 and exhalant canal 1-2 are communicated with; Having in addition sub-fraction current is from barrier film aperture 2-1Flow to barrier film 2 upper chamber, flow out from diaphragm center hole 2-2, enter exhalant canal 1-2. Even hydraulic pressure like thisIn very little situation, also can ensure considerable discharge.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not be withThis limits protection domain of the present utility model. Apparently, opening in the utility model essenceUnder showing, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that thisWithin a little improvement and modification all drop on claim protection domain of the present utility model.
