Description
Technical field
The utility model belongs to aerostatics pressure automation field, and in particular to a kind of aerostatics electric control air-release valve.
Background technique
Aerostatics goes up to the air the flexible flier of stagnant sky as a kind of by buoyancy, and internal pressure control is most important.It deflates
The important component that valve is adjusted as aerostatics internal pressure suffers from its leakproofness, Reliability of Microprocessor, dismounting convenience higher
Requirement.
Patent 201410289689.4 discloses a kind of electric control valve and stratospheric airship intake and exhaust integrated device, will
Valve deck is divided into symmetrical two halves, and transmission complexity causes higher to required precision, is difficult to accomplish to minimize, and between two halves valve deck
Shaft at be relatively inaccessible to good sealing performance.
Patent 200920313898.2 discloses a kind of emergent air-release valve for aerostat, and vent valve need to use line handspike push rod
Motor, and vent valve lateral seal is leaned on, line handspike can not be accomplished to minimize due to the limitation of transmission direction, lean on single straight
Bar drives valve deck to move up and down, and in order to guarantee the kinematic accuracy of vertical direction, needs in addition plus two straight-bar guiding, structure are more multiple
It is miscellaneous, and only by lateral seal will lead to seal the unreliable and resistance of motion it is larger.
Existing vent valve is primarily present following defect:
1. causing valve volume to be difficult to miniaturization due to using line handspike motor or complicated mechanism.
2. the installation of general vent valve uses the aperture of valve body lip, envelop materials aperture cooperates the pressure at the utricule back side
Plate bolt presses, when this fixed form is assembled every time, since envelop materials are flexible material, therefore device to hole is more difficult.
3. vent valve seal form generally uses, side is sealed or end face plane fluting adds O-ring sealing, and there are valve deck fortune
The poorly sealed problem of the dynamic bad control of extreme position.
Utility model content
In view of the above-mentioned problems, the utility model be intended to provide a kind of repetition be dismounted easily, good seal performance, electricity small in size

Preferably, one end that pin shaft is not connect with slide bar is stretched out outside arc-shaped slot, and is fixedly connected with baffle, the baffle
Size is greater than arc-shaped slot width, deviates from pin shaft from arc-shaped slot.
Specifically, the valve deck includes lid, the annular groove for surrounding the setting of lid side, the sealing being installed in annular groove
Circle.
Further, the cylinder lower end is towards the inclined inclined-plane in tubular axis direction, and the side of lid lower end is and cylinder
Body lower end inclined-plane has the inclined-plane of same slope, and valve deck and cylinder lower end can wedging sealings.
Specifically, the flange assembly includes being set to the pressing plate on the inside of utricule gas outlet, being set to outside utricule gas outlet
The flanged plate of side is set to gasket between utricule and pressing plate and between utricule and flanged plate, between pressing plate and flanged plate
It is fastened by fastener.
The remarkable result of the utility model is:
(1) slide plate link mechanism can make full use of vent valve inner space, compact-sized, move it is smooth reliable, it can be achieved that
To the use demand of vent valve lighting, miniaturization.
(2) valve deck small range can be realized using taper and two kinds of side sealing means, pyramidal structure between valve deck and cylinder
Automatic centering, improve the sealing performance of valve.
(3) when removing, valve body module can be only removed, is avoided since utricule is that valve caused by flexible material is installed
Screw hole is difficult to the difficulty of centering, and repetition is dismounted easily.
