Abstract
A kind of valve pocket extracting tool, including cylindrical pull rod, outwardly protruding the first rotary table, the second rotary table for forming diameter and becoming larger in pull rod lower part, pull rod top is equipped with screw thread, be cased at screw thread for be threadedly engaged the nut used, pull rod sets threaded one end and is cased with Supporting cover；Open Side Down for Supporting cover, and the bushing of annular is cased with outside first rotary table, and bushing is provided with the annular groove for fixing lock tongue in the horizontal direction；The lock tongue is crescent, and quantity is two, symmetrically loaded in annular groove；The pull rod, the first rotary table, the second rotary table, bushing the center of circle on the same line.The utility model is small in size, and accurate positioning, structure is simple, is suitble to use at narrow position；Valve pocket contact area is increased, can effectively be disassembled the valve pocket in housing unit；The time for reducing maintenance, improve production efficiency.
Description
Technical field
The utility model is related to a kind of extracting tool of valve pocket, specifically a kind of electronic shutdown being exclusively used on B737-800 aircraft
The valve pocket extracting tool of valve.
Background technique
Slide plate cooperation on the lower end and product parts of valve pocket to be removed, the very high (any surface finish of the required precision of mating surface
Degree reaches 0.1um), belong to sealing surface.Since shutdown valve module has leakage, the external sealing ring on the valve pocket being disassembled will be carried out
Replacement, therefore the valve pocket being disassembled is removed from product shell component, in decomposable process, since slide plate sealing surface cannot be drawn
Wound or damage, the valve pocket being disassembled are difficult to remove.When dismantling valve pocket, maintenance personal knocks shell on wooden desktop, wants valve
Set shakes out, operates so very laborious, and since sealing ring frictional force is very big, valve pocket can not be removed out of housing unit.
Summary of the invention
A kind of valve pocket extracting tool is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art, effectively
Increase lock tongue, bushing and the contact area for being disassembled valve pocket, save maintenance time, at the same save maintenance at
This.
The technical solution of the utility model is: including cylindrical pull rod, the outwardly protruding formation diameter in pull rod lower part is gradually
The first rotary table, the second rotary table to become larger, pull rod top are equipped with screw thread, be cased at screw thread for be threadedly engaged the nut used,
Pull rod sets threaded one end and is cased with Supporting cover；Open Side Down for Supporting cover, and the bushing of annular, bushing are cased with outside first rotary table
It is provided with the annular groove for fixing lock tongue in the horizontal direction；The lock tongue is crescent, and quantity is two, is symmetrically loaded on ring
In shape slot；The pull rod, the first rotary table, the second rotary table, bushing the center of circle on the same line.
The diameter of second rotary table is less than the diameter of valve pocket to be removed.
The outer diameter of the bushing is greater than the diameter of the second rotary table.
The height of the bushing is identical as the height of the first rotary table.
The utility model has the beneficial effects that: small in size, accurate positioning, structure is simple, is suitble to use at narrow position；
Valve pocket contact area is increased, can effectively be disassembled the valve pocket in housing unit；The time of maintenance is reduced, is improved
Production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1, pull rod, 2, nut, 3, Supporting cover, 4, bushing, 5, lock tongue.
Specific embodiment
In Fig. 1, a kind of valve pocket extracting tool, including cylindrical pull rod 1, the outwardly protruding formation diameter in 1 lower part of pull rod by
The first big rotary table 6 of gradual change, the second rotary table 7.1 top of pull rod is equipped with screw thread, is cased at screw thread for using with being threadedly engaged
Nut 2.Pull rod 1 sets threaded one end and is cased with the Supporting cover 3 that Open Side Down.The bushing 4 of annular, lining are cased with outside first rotary table 6
Set 4 is provided with the annular groove for fixing lock tongue 5 in the horizontal direction.There are two lock tongues 5, is the reed of crescent, is symmetrically loaded on
In annular groove.Pull rod 1, the first rotary table 6, the second rotary table 7, bushing 4 the center of circle on the same line.The diameter of second rotary table 7 is small
In the diameter of valve pocket to be removed.The outer diameter of bushing 4 is greater than the diameter of the second rotary table 7.Position corresponding with annular groove on valve pocket to be removed
Card slot is installed.The height of bushing 4 is identical as the height of the first rotary table 6.The lower end surface of bushing 4 is located at the rotary table 7 of pull rod 1
On, it thus increases the contact area of valve pocket 4 indirectly, forms the transmitting of step power, effectively by valve pocket from shell group
It is removed in part.Lock tongue 5 is the reed of crescent, and outer ring is the circular arc that radius is 8mm, and inner ring is the circular arc of radius 12mm, is about
15mm, the widest part about 6mm, the height of lock tongue 5 and the height of annular groove match.Lock tongue 5 is small in size, can be accurately placed in quilt
In the slot for tearing valve pocket and bushing 4 open, structure is simple, is suitble to use at narrow position.In disassembly process, first by pull rod 1 and bushing 4
It is put into valve pocket to be removed, then valve pocket to be removed is slowly dialled in into the annular groove for being caught in bushing 4 on one side of lock tongue 5, another side
In card slot.Raising rod 1 passes through Supporting cover 3, then is screwed into nut 2 on pull rod 1, slowly tightens nut 2.Pull rod 1 is up
It is promoted, drives bushing 4, lock tongue 5 and valve pocket to be torn open up, valve pocket to be removed can be removed.The utility model can be mounted directly to
Interiors of products is decomposed, and attempts to remove valve pocket by the way of colliding with without maintenance personal, reduces the workload of maintenance mans,
Make to repair more convenient.
