Abstract
The present invention relates to the method for dismounting and extracting tool of plunger type pipe joint during a kind of general assembly suitable for space product.The mounting and dismounting tool on the draw-in groove of the plunger connector of plunger type pipe joint, spanner is inserted on nipple and cap nut, countertorque is applied to two spanners, unscrew cap nut, cap nut is moved to the direction away from nipple, extracting tool contradicts cap nut to prevent the movement of cap nut, extracting tool is subject to one with cap nut direction of motion identical active force, and transfer the force to plunger connector, so that plunger connector is moved to the direction away from nipple, until plunger connector is separated with nipple；Substrate is provided with short slot.Present invention reduces the dismounting limitation of the opposed pipe joint in operating space so that operating personnel's force is convenient, it is ensured that the development process of space product.
Description
Technical field
The present invention relates to hydraulic plumbing system technical field, it is applied to during space product general assembly more particularly, to one kind
The method for dismounting and extracting tool of plunger type pipe joint.
Background technology
In the hydraulic plumbing system of space product, there is a kind of connected mode of plunger type pipe joint, it has sealing
Property the characteristics of good, reliability is high, repeatable disassembly is strong, be widely used in manned spaceship, spacelab, space station etc. reliable
Property require spacecraft product high.The seal form of this plunger type, can meet with the use of different types of sealing ring
The seal request of the operating pressure from the range of 0~32MPa.The connected mode of this plunger type pipe joint, one end of pipeline
It is nipple, the other end of pipeline is plunger connector and cap nut.Pipeline assemble when, plunger connector install sealing ring with
It is inserted perpendicularly into the sealing hole of cap nut afterwards, realizes that pipeline is tightly connected.After plunger connector insertion in place, cap nut rotation
Enter the external screw thread of nipple and tighten.To ensure that cap nut will not produce loosening under the environment such as vibration, cap nut is twisted
Gluing needed before tight, determine power, and also play insurance with stainless steel wire new designs of threaded joints after leak rate detection is qualified.Space product is total
Need to experience strict test process after the completion of dress.In this process can be each because of unit exception, the change of product technology state etc.
The reason for planting various kinds is, it is necessary to the pipeline to always installing is dismantled.But space product is after the completion of general assembly, can exist in nacelle
Space that is much narrow and small, dark, almost closing, is very restricted operating space, causes operating personnel normally to apply
Power.If dismounted again after being decomposed to product by inverse process, can bring difficult to the appraisal to aspects such as economy, progresses
Loss.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of for solving plunger type pipe after the completion of space product general assembly
Pipeline connector is difficult to the method for dismounting and extracting tool of plunger type pipe joint dismantled because of locus limitation reason.
In order to reach foregoing invention purpose, the technical solution adopted for the present invention to solve the technical problems is：A kind of plunger
The method for dismounting of formula pipe joint, by the draw-in groove of the short slot insertion plunger connector on extracting tool substrate；In nipple and
Spanner is inserted on cap nut respectively, countertorque is applied to two spanners, unscrew cap nut, make cap nut to away from screw thread
The direction movement of joint, until cap nut is contradicted onto the substrate of extracting tool；Cap nut is continued to move to, dismounting work is driven
The substrate and plunger connector of tool are moved to the direction away from nipple together, until cap nut is separated with nipple, are taken
Go out plunger connector.
Another technical scheme of the invention is a kind of extracting tool of plunger type pipe joint, including substrate, the substrate
It is provided with short slot.
Wherein, length of the thickness of the substrate with the draw-in groove in the axial direction is consistent, the shape of the short slot
Match with the shape and size of the draw-in groove with size.
In the prior art, it is necessary to apply an axial tension to plunger connector after cap nut is unscrewed so that plunger connects
Head is separated with nipple.The present invention is due to using above-mentioned technical proposal so that applying is generated while unscrewing cap nut
Axial tension on plunger connector, so as to realize that plunger connector is separated with nipple, reduces to plunger connector one
Individual narrow space applies an operation room for axial tension away from the dismounting for reducing the opposed pipe joint in operating space is limited
System so that operating personnel's force is convenient, it is ensured that the development process of space product.
Brief description of the drawings
The present invention is described in further detail with specific embodiment of the invention below in conjunction with the accompanying drawings：
Fig. 1 (a)-Fig. 1 (b) is working state schematic representation of the invention.
Fig. 2 is the structural representation of extracting tool of the present invention.
Specific embodiment
Referring to Fig. 1 (a)-Fig. 1 (b), plunger connector 10 is welded in a pipeline termination, and one end of the plunger connector 10 is arranged with
Cap nut 30, another pipeline termination welding nipple 40, when pipeline is assembled, connects in the plunger in cap nut 30
Sealing ring 50 is installed on first 10, the one end of plunger connector with sealing ring is inserted perpendicularly into nipple 40, in nipple
Gluing on 40 external screw thread, cap nut 30 is threadedly coupled with the external screw thread of nipple 40, so as to realize that pipeline is tightly connected.
The lateral wall of plunger connector 10 is provided with draw-in groove 11.
Referring to Fig. 2, the extracting tool of plunger type pipe joint of the invention includes substrate 20, and the substrate 20 is provided with scarce
Groove 22.Length of the thickness of the substrate 20 with the draw-in groove 11 in the axial direction is consistent, the shape of the short slot 22 and
Size matches with the shape and size of the draw-in groove 11.
The detailed process for dismantling plunger type pipe joint using above-mentioned extracting tool is as follows：
（1）By in the draw-in groove of the short slot insertion plunger connector on extracting tool substrate；
（2）Two spanners corresponding with the size of cap nut and the size of nipple respectively are taken, spanner is distinguished
On the outer-hexagonal of embedded cap nut and nipple；
（3）Opposite force is applied to two spanners, loosening is produced to cap nut, note the stability and uniformity of force,
Avoid causing coming off or gouge equipment surface for spanner；
（4）Uniformly exerted a force with spanner, cap nut is exited on the external screw thread from nipple, cap nut with dismounting
After the substrate of instrument is contradicted, cap nut, extracting tool and plunger connector will turn into the side that an entirety is exited along cap nut
To motion.Additionally, because scribbling locking glue on screw thread, during note the cleaning and protection of fifth wheel.
（5）When cap nut is separated with nipple, plunger connector has also been exited from nipple substantially, can be very
Easily plunger connector and nipple are disconnected.
The distance of cap nut opposite thread joint movement determines what plunger connector energy opposite thread joint was automatically moved
Distance.According to fitted position chain relation, although the length that plunger connector is connected with nipple connects more than cap nut with screw thread
The length of head connection, but when cap nut is separated with nipple, sealing ring on plunger connector with screw thread
Joint is separated, and plunger connector is changed into gap cooperation with nipple, therefore can easily take out plunger connector.
（6）Plunger tube joint disassembly instrument is pulled down from plunger connector, is properly preserved.
Using effect proves that the extracting tool simple structure of this plunger type pipe joint, low cost, method are ingenious effectively,
Operating personnel can be facilitated carries out the dismounting of pipe joint, and product will not be caused to damage.
