Abstract

The utility model relates to a flexible connector assembling and disassembling technique, in particular to a special tool for assembling and disassembling a gas-pipeline flexible connector. The special tool solves the problem that the flexible connector is difficult to assemble and disassemble. The special tool for assembling and disassembling the gas-pipeline flexible connector comprises two T-shaped insertion pieces, a bolt and a hand wheel, wherein horizontal notches are formed in two ends of the horizontal portions of the T-shaped insertion pieces, longitudinal notches are formed at the ends of the longitudinal portions of the T-shaped insertion pieces, the positions of the two T-shaped insertion pieces right face towards each other, two ends of the bolt respectively penetrate through the longitudinal notches of the two T-shaped insertion pieces, and the hand wheel is positioned at the tail end of the bolt. The special tool is suitable for assembling and disassembling the flexible connector when a gas pipeline is overhauled.

Description

A kind of gas pipeline flexible joint tool specially for attaching and detaching
Technical field
The utility model relates to flexible joint dismounting technology, specifically is a kind of gas pipeline flexible joint tool specially for attaching and detaching.
Background technology
Flexible joint is a kind of conduit coupling that is widely used in metallurgy, chemical industry, gas industry, and it is mainly used in connecting apparatus for rotating and gas pipeline, and the vibrations that purpose produces when being the operation of blocking-up apparatus for rotating cause damage to avoid vibrations to gas pipeline.During actual the use, as shown in Figure 3, the two ends of flexible joint 6 are connected with the gas pipeline 7 of both sides by flange 8 respectively.During the maintenance gas pipeline, flexible joint need be dismantled.After maintenance finishes, then need flexible joint is installed again.The demounting procedure of flexible joint is: earlier flange bolt 9 is dismantled, then with flexible joint 6 from taking out between the flange 8 of both sides.The installation steps of flexible joint are: flexible joint 6 is clipped between the flange 8 of both sides the flange bolt 9 of screwing on then earlier.Practice shows, at the dismounting diameter during greater than the flexible joint of 150mm, because flexible joint has bigger axial expansion power, even dismantle flange bolt, flexible joint also can be clipped in tightly between the flange of both sides and be difficult to take out, and causes the dismounting difficulty of flexible joint.In like manner, when diameter was installed greater than the flexible joint of 150mm, because flexible joint has bigger axial expansion power, setter was difficult to flexible joint is clipped between the flange of both sides, causes the installation difficulty of flexible joint.Based on this, be necessary to invent a kind of brand-new flexible joint dismantling device, to solve the problem of flexible joint dismounting difficulty.
Summary of the invention
The utility model provides a kind of gas pipeline flexible joint tool specially for attaching and detaching in order to solve the problem of flexible joint dismounting difficulty.
The utility model is to adopt following technical scheme to realize: a kind of gas pipeline flexible joint tool specially for attaching and detaching comprises T shape inserted sheet, bolt and handwheel; The two ends of the lateral part of T shape inserted sheet respectively have a horizontal gap; The end of the longitudinal component of T shape inserted sheet has vertical gap; The number of T shape inserted sheet is two, and two T shape inserted sheet positions over against; Vertical gap of two T shape inserted sheets is run through at the two ends of bolt respectively; Handwheel is installed on the tail end of bolt.
During use, the supporting use of two a kind of gas pipeline flexible joint tool specially for attaching and detaching described in the utility model, as shown in Figure 4.Concrete use is as follows: when the dismounting flexible joint, earlier flange bolt is dismantled, four T shape inserted sheets are rapped in the gap of inserting two side flanges respectively with hand hammer then, and guarantee that four T shape inserted sheets lay respectively at four diagonal positions of flange, forward rotation handwheel subsequently, make bolt carry out forward rotation, four T shape inserted sheets are drawn close under the drive of bolt gradually, and extruding flexible joint, make the gap between flexible joint and two side flanges increase, just can like a cork flexible joint be taken out between the flange of both sides thus, thereby easily finish the dismounting of flexible joint.When flexible joint is installed, four T shape inserted sheets are rapped in the gap of inserting two side flanges respectively with hand hammer earlier, and guarantee that four T shape inserted sheets lay respectively at four diagonal positions of flange, backward rotation handwheel then, make bolt carry out backward rotation, four T shape inserted sheets under the drive of bolt gradually away from, like a cork flexible joint is clipped between the flange of both sides subsequently, and flange bolt screwed on, thereby easily finish the installation of flexible joint.Based on said process, a kind of gas pipeline flexible joint tool specially for attaching and detaching described in the utility model has been realized the light dismounting of flexible joint, efficiently solves the problem of flexible joint dismounting difficulty.
The utility model is rational in infrastructure, design is ingenious, efficiently solves the problem of flexible joint dismounting difficulty, dismounting and the installation of flexible joint when being applicable to the gas pipeline maintenance.

The specific embodiment
A kind of gas pipeline flexible joint tool specially for attaching and detaching comprises T shape inserted sheet 1, bolt 2 and handwheel 3; The two ends of the lateral part of T shape inserted sheet 1 respectively have a horizontal gap 4; The end of the longitudinal component of T shape inserted sheet 1 has vertical gap 5; The number of T shape inserted sheet 1 is two, and two T shape inserted sheet 1 positions over against; Vertical gap 5 of two T shape inserted sheets 1 is run through at the two ends of bolt 2 respectively; Handwheel 3 is installed on the tail end of bolt 2;
During concrete enforcement, T shape inserted sheet 1 adopts steel plate to make, and its thickness is 3mm.Bolt 2 is M8 type plain bolt.Handwheel 3 is the handwheel of DN80 type slide valve.
