Abstract
The utility model relates to a high-pressure pipeline compensator, which is composed of a special pipe, a telescopic pipe, a sealing element and a fastening element, wherein, the sealing and the pipe-shaped structure are suitable for resisting the high-pressure of the pipe, which is used for compensating the axial displacement of a long pipeline caused by the temperature variation. The utility model is particularly suitable for the compensation of the pipeline of the high-pressure liquid conveying. The utility model has the advantages that the structure is simple, the cost is low, and the processing and the installation are easy.
Description
The utility model relates to a kind of pipe joint that allows the adjustable connection of a large amount of axial adjustment, in order to compensate the pipeline axial displacement that causes because of expanding with heat and contract with cold, be applicable to the pipeline of carrying various fluids, be particularly useful for water delivery, oil transportation or the gas pipeline of work under the high pressure conditions.
The utility model technology is to the improvement by the CN91205115.9 patented technology of claimant and fellows thereof all " high pressure pipe line breathing compensator " by name, and this correlation technique is by special pipe and be contained in telescopic pipe in its butt end and the seal arrangement between two pipes, the positioning ring that is threaded at the telescopic pipe left end constitute.This technology has produced tangible benefit in that some low pressure and high pressure (more than the 2MPa) occasion are on probation, yet this new technology is found sth. annoying or trying trivial in some the part processing and the installation of structure slightly, and under higher pressure (tens of MPa), seem fragile, be necessary to improve.
The pressure that the purpose of this utility model is to simplify the structure of correlation technique and increases its tolerance.Its scheme is:
A kind of high pressure pipe line compensator, constitute by special pipe, telescopic pipe, the positioning ring that is threaded in telescopic pipe one end and the seal arrangement between two pipes, it is characterized in that seal arrangement is made of the metal washer, flexible seal ring, flange tube, outer flange plate and the bolt of special pipe butt end that are between two pipes; Metal washer and flexible seal are contained between special pipe the butt end interior seal groove and telescopic pipe, and the flange tube is from an end packing washer and a seal ring, with bolton flange tube and the outer flange plate of special pipe.
The utility model is with flange tube packing washer and seal ring, and saved thread regulator and spring propulsion, makes designs simplification, processing, installs and all make things convenient for, and removed the part-structure of extremely high pressure performance fragility down, improves withstand voltage performance.
Further specify structure of the present utility model below in conjunction with accompanying drawing by embodiment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is embodiment's a structural representation.
Embodiment is the high pressure pipe line compensator that a special pipe, telescopic pipe, positioning ring and seal arrangement constitute.Telescopic pipe 1 is in the inside of special pipe butt end 2, and positioning ring 3 is threaded at the telescopic pipe left end.Car goes out the seal groove 4 of certain depth in the special pipe butt end, makes the inwall of pipe have step N+1 that two kinds of different inner diameters form.The seal ring 6 that metal washer 5 an and N Expanded graphite is made alternately is enclosed within outside the pipe 1 within the groove 4, constitutes N level seal ring (N=1,2,3 ...), the better seal effect is arranged.Flange tube 7 compresses this N level seal ring from right-hand member.Bolt 8 is fastened on flange tube 7 on the outer flange plate 9 of special pipe.The flange tube is the cylinder that one one end has flange plate, and its internal diameter is greater than the external diameter of tube 1, and its external diameter is less than the internal diameter of tube 2.Disperse for making special pipe change bore place stress, garden arc-shaped transition section 10 is made at this place.
Claims (5)
1, a kind of high pressure pipe line compensator, constitute by special pipe, telescopic pipe, the positioning ring that is threaded in telescopic pipe one end and the seal arrangement between two pipes, it is characterized in that seal arrangement is made of the metal washer, flexible seal ring, flange tube, outer flange plate and the bolt of special pipe butt end that are between two pipes; Metal washer and flexible seal ring are contained between special pipe the butt end interior seal groove and telescopic pipe, and the flange tube is from an end packing washer and a seal ring, with bolton flange tube and the outer flange plate of special pipe.
2, compensator according to claim 1 is characterized in that, the seal arrangement between two pipes has one and by N+1 metal washer and N flexible seal ring N level seal ring (N=1,2,3 that constitute is installed alternately ...).
