A kind of Lever-type stop valve with spring reset, comprise four screw-in straight couplings, flap, spring, valve body, valve gap, filler underlay, middle Packing seat, filler pads, plane sealing nut, first nut, valve rod push-and-pull extension bar, 4 bearing pins, piston rod connecting sheet, piston rod, second nut and stud, piston cap, piston, pull bar, lever, it is characterized in that, plane sealing nut is adopted to be connected between valve body with valve gap, first screw-in straight coupling and flap compress, second screw-in straight coupling accesses from valve body side, flap, valve rod, closely be connected between piston and piston rod, by filler underlay between valve rod and valve gap, middle Packing seat, pad sealing on filler, spring is arranged between valve gap and flap, lever, piston rod connecting sheet, between valve rod push-and-pull extension bar and pull bar respectively by three pinned connection together, be provided with the first nut between valve rod push-and-pull extension bar and plane sealing nut, piston cap is arranged on valve body by the second nut and stud, and the 3rd screw-in straight coupling, the 4th screw-in straight coupling access a two-position three way magnetic valve respectively, and the switch of these two two-position three way magnetic valves is contrary.
Preferred as technique scheme, first, second, third and fourth screw-in straight coupling described all seals with O type circle.
Preferred as technique scheme, described flap, valve rod, piston and piston rod also can be made into integrated formed structure.
A kind of Lever-type stop valve with spring reset that the utility model embodiment provides, compared with prior art, advantage of the present utility model is just: switch is rapid, structure is simple, easy to use, size diminishes, accurate positioning, stable performance, topology layout is reasonable, compact, has installed two-position three way magnetic valve, and this valve switch frequency is accelerated; The reset response of spring, makes sealing effect better; Valve can be made when hoisting capacity is very little, switching frequency can also be accelerated, valve takes up space reduction, this solenoid valve leaks outside absolutely stifled, interior leakage is easily controlled, make valve more safe and reliable, operation and maintenance cost and the maintenance difficulty in later stage also reduce greatly, can also be applied in tank, aircraft, satellite etc. in military weapon.

Fig. 4 is that the B-B of a kind of Lever-type stop valve with spring reset of the utility model embodiment is to cross-sectional view.In figure: 1-first screw-in straight coupling, 2-flap, 3-second screw-in straight coupling, 4-spring, 5-valve body, 6-valve gap, 7-filler underlay, Packing seat in 8-, 9-filler pads, 10-plane sealing nut, 11-first nut, 12-valve rod push-and-pull extension bar, 13-first bearing pin, 14-piston rod connecting sheet, 15-second bearing pin, 16-piston rod, 17, stud, 18-second nut, 19-piston cap, 20 the 3rd screw-in straight couplings, 21-piston, 22-the 4th screw-in straight coupling, 23-pull bar, 24-bearing pin, 25-lever.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-4, a kind of Lever-type stop valve with spring reset that the utility model embodiment provides, valve body 5, valve gap 6 connects with plane sealing nut 10, first screw-in straight coupling 1 compresses with flap 2 and seals, flap 2, valve rod, piston 21 and piston rod 16 are all made of one formula, valve rod and valve gap 6 filler underlay 7, middle Packing seat 8, filler pads 9 sealings, first, two, three, four screw-in straight couplings all seal with O type circle, lever 25 and piston rod connecting sheet 14, valve rod push-and-pull extension bar 12, pull bar 23 uses three pinned connection together respectively, the position of pull bar 23 is changeless, 3rd screw-in straight coupling 20, 4th screw-in straight coupling 22 connects a two-position three way magnetic valve respectively, this solenoid valve is the drive unit of the Lever-type stop valve of this band spring reset.The switch of these two two-position three way magnetic valves must be contrary, if the two-position three way magnetic valve be namely connected on the 3rd screw-in straight coupling 20 is open mode, the two-position three way magnetic valve be then connected on the 4th screw-in straight coupling 22 is closed condition, and vice versa.
When the 4th screw-in straight coupling 22 is states that valve is opened, pressurized air will enter into the lower part of piston 21 continuously, and now the 3rd screw-in straight coupling 20 is valve closed conditions, the upper part pressurized air of piston 21 communicates with ambient atmosphere, will be discharged, piston rod 16 will move up, under the effect of lever 25, flap 2 will move up, spring 4 can compress, and is applied to the active force that flap 2 one is downward, now valve open, medium, such as I2 steam just can have passed smoothly.
When the 3rd screw-in straight coupling 20 is states that valve is opened, pressurized air will enter into the upper part of piston 21 continuously, and now the 4th screw-in straight coupling 22 is valve closed conditions, the lower part pressurized air of piston 21 communicates with ambient atmosphere, will be discharged, piston rod 16 will move down, under the effect of lever 25, flap 2 will move down, spring 4 can extend, be applied to the active force that flap 2 one is downward, valve is closed rapidly, and the power needed for valve closing is reduced.So move in circles, valve can be made when hoisting capacity is very little, can also switching frequency be accelerated.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
