Description
Technical field
A kind of synchronous mode dismounting belongs to field of fluid machinery from seal structure, is related to a kind of design dismounted from seal structure.
Background technology
Dismounting from seal structure in field of fluid machinery, especially Aviation Fuel system it is in an increasingly wide range of applications.
There is lot of advantages from the product of seal structure using dismounting, product maintenance can be significantly improved, reliability is improved.
Dismounting is varied from seal structure, in Aviation Fuel system, have using it is synchronous open or self-styled fluid intake and
Demand of the dismounting of fluid issuing from seal structure.
The content of the invention
The purpose of the present invention：A kind of synchronous mode dismounting is provided from seal structure, reduction dismounting improves reliable from seal structure flow resistance
Property, it is provided simultaneously with error-disable function.
Technical scheme：Scheme such as Fig. 1.Housing 1 is sealed in fluid system configuration by sealing ring 2；Screw 3 will
Sealing drum 4 and chipware 5 are fixed on housing 1；Sealing ring 6 seals sealing drum 4 and body clearance；Sealing ring 7 is by chipware and close
Sealed tube clearance seal；Valve body 8 is arranged on housing 1 by screw 9, and sealing therebetween is ensured by sealing ring 10；Spring 11
The top that valve core 12 inside valve body 8 is compressed and makes the push rod 13 on valve core 12 contact chipware 5, moulding
14 ensure sealing therebetween when valve core 12 contacts housing 1；Locating rod 15, which is arranged on sealing drum 4, to be used to be oriented to；Gag lever post
16 and limit spring 17 be arranged on housing 1 on.Push rod 13 designs suitably sized, loads the assembly of sealing drum 4 and chipware 5
Or when extracting housing 1, fluid intake 18 and fluid issuing 19 are synchronously opened or closed.The overhanging step auricle 20 of gag lever post 16 blocks
On sealing drum 4 and chipware 5, do not deviate from the aperture 21 time limit coremaking part 5 on housing 1 in locating rod 15, prevent it close from deviating from
Sealed tube 4；Locating rod 15 rotates to an angle when deviating from the aperture 21 on housing 1 and chipware 5 can be deviate from into sealing drum 4；Step
The limitation sealing drum 4 of auricle 20 can not deviate from housing 1 all the time.
Beneficial effects of the present invention：The present invention can be extensively using fluid-mechanic system, especially aircraft fuel system.This hair
It is bright easy to implement, it is possible to decrease dismounting improves reliability from seal structure flow resistance, being capable of systematically mistake proofing.
