Abstract
The invention relates to a disassembling method and a disassembling tool for a plunger type pipe joint in an aerospace product final assembly process. The disassembling method comprises the steps of: installing the disassembling tool on the clamping slot of a plunger joint of the plunger type pipe joint; inserting a spanner into each of a screwed joint and a jacket nut; applying counter torque on the two spanners and unscrewing the jacket nut to move along the direction far away from the screwed joint; the disassembling tool being abutted against the jacket nut to stop the jacket nut moving; under the applied force of which the direction is the same with the moving direction of the jacket nut, the disassembling tool transmitting the applied force to the plunger joint to move the plunger joint along the direction far away from the screwed joint, till the plunger joint is separated from the screwed joint. A substrate is provided with a notch. According to the disassembling method and the disassembling tool for the plunger type pipe joint, the disassembling restriction on the plunger type pipe joint by operation space is reduced, operators can apply force more conveniently, and the development process of aerospace products is ensured.
Description
Technical field
The present invention relates to hydraulic plumbing system technical field, especially relate to a kind of method for dismounting and the extracting tool that are applicable to space product total process of assembling center pillar plug pipe joint.
Background technology
In the hydraulic plumbing system of space product, there is a kind of connected mode of plunger type pipe joint, its have good airproof performance, reliability high, the strong feature of disassembly can be repeated, be widely used in the high spacecraft product of the reliability requirements such as manned spaceship, spacelab, space station.The seal form of this plunger type, can meet the seal request from the operating pressure within the scope of 0 ~ 32MPa with the use of dissimilar sealing ring.The connected mode of this plunger type pipe joint, one end of pipeline is nipple, and the other end of pipeline is plunger connector and cap nut.During pipeline assembling, plunger connector in the vertical closed hole inserting cap nut, realizes line seal and connects after installing sealing ring.After plunger connector insertion puts in place, cap nut screws in the external screw thread of nipple and tightens.Loosening for guaranteeing that cap nut can not produce under the environment such as vibration, cap nut needs gluing, determines power before tightening, and also plays insurance by stainless steel wire new designs of threaded joints after leak rate detection is qualified.Need after space product general assembly completes to experience strict test process.Can, because of various reasons such as unit exception, the changes of product technology state, the pipeline to always installing be needed to dismantle in this process.But space product is after general assembly completes, much spaces that is narrow and small, dark, that almost close can be there is in the body of cabin, operating space is very restricted, causes operating personnel normally to exert a force.If carry out dismounting again after decomposing product by inverse process, then bring loss difficult to the appraisal can to the aspect such as economy, progress.
In prior art, after unscrewing cap nut, need to apply an axial tension to plunger connector, plunger connector is separated with nipple.The present invention is owing to adopting technique scheme, the axial tension be applied on plunger connector is created while making to unscrew cap nut, thus realize being separated of plunger connector and nipple, decrease operation room distance plunger connector being applied to an axial tension at a narrow space, reduce operating space to limit the dismounting of plunger type pipe joint, operating personnel are exerted a force conveniently, ensure that the development process of space product.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly completes rear pillar plug pipe joint because of locus limitation reason be difficult to the method for dismounting of plunger type pipe joint dismantled and extracting tool for solving space product general assembly.
In order to reach foregoing invention object, the technical solution adopted for the present invention to solve the technical problems is: a kind of method for dismounting of plunger type pipe joint, is embedded by the short slot on extracting tool substrate in the draw-in groove of plunger connector; Nipple and cap nut insert spanner respectively, countertorque is applied to two spanners, unscrews cap nut, cap nut is moved to the direction away from nipple, until cap nut is conflicted on the substrate of extracting tool; Continue mobile cap nut, drive the substrate of extracting tool to move to the direction away from nipple together with plunger connector, until cap nut is separated with nipple, take out plunger connector.
Another technical scheme of the present invention is a kind of extracting tool of plunger type pipe joint, comprises substrate, and described substrate is provided with short slot.
Wherein, the thickness of described substrate is consistent with described draw-in groove length in the axial direction, and the shape and size of described short slot and the shape and size of described draw-in groove match.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiments of the invention, the present invention is described in further detail:
Fig. 1 is working state schematic representation of the present invention.
Fig. 2 is the structural representation of extracting tool of the present invention.
Detailed description of the invention
See Fig. 1, a pipeline termination welding plunger connector 10, one end of this plunger connector 10 is arranged with cap nut 30, another pipeline termination welding nipple 40, during pipeline assembling, the plunger connector 10 being positioned at cap nut 30 installs sealing ring 50, plunger connector is vertically inserted in nipple 40 with one end of sealing ring, gluing on the external screw thread of nipple 40, cap nut 30 is threaded with the external screw thread of nipple 40, thus realizes line seal connection.The lateral wall of plunger connector 10 is provided with draw-in groove 11.
See Fig. 2, the extracting tool of plunger type pipe joint of the present invention comprises substrate 20, and described substrate 20 is provided with short slot 22.The thickness of described substrate 20 is consistent with described draw-in groove 11 length in the axial direction, and the shape and size of described short slot 22 and the shape and size of described draw-in groove 11 match.
Use the detailed process of above-mentioned extracting tool dismounting plunger type pipe joint as follows:
(1) short slot on extracting tool substrate is embedded in the draw-in groove of plunger connector;
(2) get two corresponding with the size of cap nut and the size of nipple respectively spanners, spanner is embedded respectively on the outer-hexagonal of cap nut and nipple;
(3) opposite force is applied to two spanners, produce to cap nut and loosen, note stability and the uniformity of force, avoid causing coming off or gouge equipment surface of spanner;
(4) evenly exert a force with spanner, cap nut is exited from the external screw thread nipple, after the substrate of cap nut and extracting tool is conflicted, cap nut, extracting tool move becoming the as a whole direction exited along cap nut with plunger connector.In addition, because screw thread scribbling locking glue, cleaning and the protection of fifth wheel in process, is noted.
(5) when cap nut is separated with nipple, plunger connector is also basic to be exited from nipple, can plunger connector and nipple be disconnected easily.
The distance of cap nut opposite thread joint movement determines the distance of plunger connector energy opposite thread joint movement automatically.According to fitted position chain relation, although the length that plunger connector is connected with nipple is greater than the length that cap nut is connected with nipple, but when cap nut is separated with nipple, the sealing ring be arranged on plunger connector is separated with nipple, plunger connector and nipple become matched in clearance, therefore can take out plunger connector easily.
(6) plunger tube joint disassembly instrument is pulled down from plunger connector, properly preserve.
Result of use proves, the extracting tool structure of this plunger type pipe joint is simple, cost is low, and method is effectively ingenious, and energy handled easily personnel carry out the dismounting of pipe joint, and can not cause damage to product.
