Abstract
The utility model discloses a kind of steel pipe connection structure, the technical problem that spliced steel pipe gap hinders the inner piston ring doing back and forth movement to cause piston movement to be obstructed can be solved.Comprise steel pipe one, steel pipe two, sleeve pipe and flange plate, steel pipe one and steel pipe two dock, the outer installment sleeve pipe of joint, and the two ends of sleeve pipe are fixedly connected with flange plate respectively, flange plate is fixed on steel pipe, and the end face of the docking of described steel pipe one and steel pipe two is set to inclined-plane.A kind of steel pipe connection structure of the present utility model is by being arranged to inclined-plane the end face of docking, the gap that two interfaces are formed is not on a vertical surface, and piston ring is generally vertical with steel pipe, such piston ring is along with piston is when moving back and forth, and the gap formed with gap is enclosed and being in staggered interting and mistake all the time, when not have coincidence, so not easily hindered by gap circle or block, make piston movement unblocked, increase work efficiency, simple and practical.
Description
Technical field
The utility model relates to a kind of linkage structure, is specifically related to a kind of steel pipe connection structure.
Background technique
The design mainly for steel pipe on cylinder because of need lengthen splicing time a kind of linkage structure.Namely so-called cylinder guides piston in cylinder, carry out the cylindrical metal parts of straight reciprocating motion; Gas receiving piston in compresser cylinder compresses and improves pressure; Thermal energy is mechanical energy by expanding by working medium in cylinder; The housing of turbo machine, rotary engine etc. also claims " cylinder " usually.The application of cylinder in general field does not need oversize length substantially, but at some special dimensions such as aircraft carrier, catapult on aircraft is with regard to need the steel pipe of cylinder to reach kinetic force that certain length could produce needs, because longer steel pipe is difficult to disposable casting out, just need the steel pipe of different length to splice to realize, traditional joining method is all that the connecting end surface of steel pipe is cut into plane, then fixing by flange docking, this connecting method, the gap of stitching portion is on a vertical surface, because cylinder interior has piston moving reciprocatingly, piston is the part that is stressed in cylinder, for preventing the two mutual gas blowbies in chamber about piston, be provided with piston packing and be also piston ring, for the gap at a vertical surface, piston packing is when moving across, probably to be stuck or interrupted, piston movement is caused to be prevented from or not smooth.
Model utility content
The purpose of this utility model is to provide a kind of steel pipe connection structure, can solve the technical problem that spliced steel pipe gap hinders the inner piston ring doing back and forth movement to cause piston movement to be obstructed.
For achieving the above object, the utility model have employed following technological scheme:
A kind of steel pipe connection structure, comprise steel pipe one, steel pipe two, sleeve pipe and flange plate, steel pipe one and steel pipe two dock, the outer installment sleeve pipe of joint, and the two ends of sleeve pipe are fixedly connected with flange plate respectively, flange plate is fixed on steel pipe, and the end face of the docking of described steel pipe one and steel pipe two is set to inclined-plane.
Preferably, the end face joint polishing of the docking of described steel pipe one and steel pipe two is level and smooth.
Preferably, described flange plate is welded on steel pipe.
Preferably, described sleeve pipe and flange plate are connected by screw.
As shown from the above technical solution, a kind of steel pipe connection structure of the present utility model is by being arranged to inclined-plane the end face of docking, the gap that two interfaces are formed is not on a vertical surface, and piston ring is generally vertical with steel pipe, and such piston ring is along with piston is when moving back and forth, the gap formed with gap is enclosed and being in staggered interting and mistake all the time, when not having to overlap, so not easily hindered by gap circle or block, make piston movement unblocked, increase work efficiency, simple and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
The corresponding name of reference character shown in figure is called:
1, steel pipe one; 2, steel pipe two; 3, sleeve pipe; 4, flange plate; 5, screw.
Embodiment
Below in conjunction with accompanying drawing, technological scheme disclosed in the utility model is described further:
As shown in Figure 1, a kind of steel pipe connection structure of the present embodiment, comprise steel pipe 1, steel pipe 22, sleeve pipe 3 and flange plate 4, steel pipe 1 and steel pipe 22 dock, the outer installment sleeve pipe 3 of joint, the two ends of sleeve pipe 3 are fixedly connected with flange plate 4 respectively, and flange plate 4 is fixed on steel pipe, and the end face of the docking of described steel pipe 1 and steel pipe 22 is set to inclined-plane.
The joint sealant sealing of above steel pipe 1 and steel pipe 22, can prevent gas leakage.
Selected sleeve pipe 3 is for the fixing and protection after steel pipe 1 and steel pipe 22 being docked above, and sleeve pipe 3 two ends are connected by screw 5 with flange plate 4 respectively again, and flange plate 4 is welded on steel pipe, for further fixed sleeving 3.Screw 5 installation and removal easy to connect.
The end face joint polishing of the docking of described steel pipe 1 and steel pipe 22 is level and smooth, and namely two interfaces are level and smooth in both sides, the gap polishing that steel duct is formed, in case there is the burr of end face to hinder piston and piston ring to move reciprocatingly.
As shown from the above technical solution, a kind of steel pipe connection structure of the present embodiment is by being arranged to inclined-plane the end face of docking, the gap that two interfaces are formed is not on a vertical surface, and piston ring is generally vertical with steel pipe, and such piston ring is along with piston is when moving back and forth, the gap formed with gap is enclosed and being in staggered interting and mistake all the time, when not having to overlap, so not easily hindered by gap circle or block, make piston movement unblocked, increase work efficiency, simple and practical.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
