The utility model solves the technological scheme that its technical problem adopted:
A kind of flap formula pilot solenoid valve comprises valve body, is provided with valve rod, main valve clack support and main valve clack in the valve body, it is characterized in that: be provided with guide's device between main valve clack support and valve rod, and the gas of air-inlet cavity can flow to outlet chamber through the unlatching of guide's device.
Said guide's device comprises first pod apertures that is arranged on the main valve clack support and the receiving cavity that communicates with first pod apertures; Be provided with the pilot valve shaft bar that can move up and down along first pod apertures in first pod apertures; And the pilot valve shaft bar is connected with valve rod; The pilot valve shaft bar is provided with guide's flap that can seal first pod apertures and flap baffle plate that can jack-up main valve clack support; And the flap baffle plate is arranged in receiving cavity, and the pilot valve shaft bar is provided with the resetting-mechanism that the pilot valve shaft bar is resetted.
Said resetting-mechanism comprises the Returnning spring that is arranged on the valve rod.
Be provided with spring seat in the said valve body, said Returnning spring one end roof pressure is on spring seat, and the other end roof pressure is formerly on the pilot stem support.
Said flap baffle plate is provided with second pod apertures.
Be provided with the valve rod fixture block between said pilot valve shaft bar and valve rod, and the pilot valve shaft bar is installed on the valve rod through the valve rod fixture block.
The beneficial effect of the utility model is: the utility model is provided with guide's device between main valve clack support and valve rod; And the gas of air-inlet cavity can flow to outlet chamber through the unlatching of guide's device, thereby before main valve clack support and main valve clack were opened, air-inlet cavity and outlet chamber be UNICOM; The pressure that acts on main valve clack support and main valve clack is very little; Thereby the active force that needed electromagnetic coil is produced when having reduced to drive valve has also reduced the latus rectum of electromagnetic coil, so has also reduced the cost of production of solenoid valve; Simple in structure, reliable in action.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sectional view of the utility model;
Fig. 2 is the sectional view of the old structure of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2; The utility model discloses a kind of flap formula pilot solenoid valve; Comprise valve body 1; Be provided with valve rod 2, main valve clack support 3 and main valve clack 4 in the valve body 1, main valve clack 4 supports 3 and 2 of valve rods are provided with guide's device, and the gas of air-inlet cavity 5 can flow to outlet chamber 6 through the unlatching of guide's device.
As shown in the figure; Guide's device comprises first pod apertures 7 that is arranged on main valve clack 4 supports 3 and the receiving cavity 8 that communicates with first pod apertures 7; Be provided with the pilot valve shaft bar 8 that can move up and down along first pod apertures 7 in first pod apertures 7, and pilot valve shaft bar 8 is connected with valve rod 2, pilot valve shaft bar 8 is provided with guide's flap 9 that can seal first pod apertures 7 and flap baffle plate 10 that can jack-up main valve clack support 3; And flap baffle plate 10 is arranged in receiving cavity 8; In order to strengthen the gas stream output, flap baffle plate 10 is provided with second pod apertures 11, and is above-mentioned certainly just preferred; Gas can flow out from the gap of flap baffle plate 10 and receiving cavity 8; Guide's flap 9 is fixed through the fixed groove that is arranged on guide's flap 9 supports, and flap baffle plate 10 is fixed on guide's flap support 8 through circlip for shaft 12, and pilot valve shaft bar 8 is provided with the resetting-mechanism that pilot valve shaft bar 8 is resetted.Further; 2 of pilot valve shaft bar 8 and valve rods are provided with valve rod fixture block 13, and pilot valve shaft bar 8 is installed on the valve rod 2 through valve rod fixture block 13, and concrete mode does; Riveted fixing has the valve rod fixture block 13 of U-shaped opening on guide's flap support 8, is connected with valve rod 2 through valve rod fixture block 13 again.
