Abstract

The invention discloses a double-flange limiting telescopic joint, and belongs to the field of a telescopic joint. The double-flange limiting telescopic joint comprises a body, a quincuncial pressing cover, a limiting screw rod, a limiting nut, a limiting ring, a limiting telescopic pipe and a hexagonal bolt, wherein two end parts of the body are respectively provided with a first flange and a second flange, and the quincuncial pressing cover is arranged on the body and is connected with the first flange through the hexagonal bolt; the limiting ring is arranged on the body in a sleeving way, the limiting screw rod is arranged on the limiting ring through a through hole in the quincuncial pressing cover, one end of the limiting screw rod is connected with the first flange, the limiting nut is arranged at one side, which is close to the quincuncial pressing cover, of the other end of the limiting screw rod, and the limiting telescopic pipe is arranged at one side, which is close to the second flange, of the other end of the limiting screw rod. The double-flange limiting telescopic joint disclosed by the invention has the advantages of simple structure, convenience in installation, high strength, good pressure resistance, small vibration, good using effect and long service life.

Description

A kind of two flange limit expansion joint
Technical field
The present invention relates to expansion joint field, specifically, relate to a kind of two flange limit expansion joint.
Background technique
Compensation of pipeline joint is pump, valve, the new product that the equipment such as pipeline are connected with pipeline, by bolt, they are coupled together, become entirety, and have certain displacement amount, so just when installation and maintenance, can adjust according to in-site installation size, operationally, end thrust can be passed also to whole pipe-line system.So not only increase work efficiency, and certain protective role is played to the pipe-line equipment such as pump, valves.But current a lot of a lot of joint strength is inadequate, bears limited pressure, vibrations are large, and using effect is bad, and working life is shorter.
Summary of the invention
The technical problem solved
For overcoming the technical problem existed in prior art, the invention provides that a kind of structure is simple, easy for installation, intensity is large, resistance toly to press, shake little, using effect good, two flange limit expansion joints of long service life.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of two flange limit expansion joint, comprises body, quincunx gland, Limit screw, stop nut, position limit cycle, limit telescopic pipe and hex head bolt; The two end part of described body are respectively equipped with the first flange and the second flange, and described quincunx gland is located on body, and quincunx gland is connected by hex head bolt with the first flange; Described position limit cycle is sheathed on body, described Limit screw is arranged on position limit cycle by the through hole on quincunx gland, one end of Limit screw is connected with the first flange, its the other end is provided with stop nut in the side near quincunx gland, and its other end is provided with limit telescopic pipe in the side near the second flange.
Further, described limit telescopic pipe and stop nut are located at the both sides of position limit cycle respectively.
Further, the described end being arranged on the hex head bolt on quincunx gland is provided with nut.
Beneficial effect
Compared with prior art, the present invention has following remarkable advantage:
1, expansion joint of the present invention is applicable to both sides all and Flange joint, the connecting length of product two ends and flange is adjusted during installation, gland bolt is evenly tightened successively in diagonal angle, adjust stop nut again, so just can allow pipeline can free-extension within the scope of extending amount, locking stretching amount, guarantees the safe operation of pipeline.Two flange limit expansion joint can prevent pipeline from causing leakage and the damage of compensating joint because of excess displacement, is mainly used in permission displacement range, absorb axial displacement and is connected with the pipeline pine cover bearing axial pressure thrust.
2, expansion joint structure of the present invention is simple, easy for installation, intensity is large, resistance toly to press, shake little, using effect good, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, body, 2, quincunx gland, 3, Limit screw, 4, stop nut, 5, position limit cycle, 6, limit telescopic pipe, 7, hex head bolt, the 8, first flange, the 9, second flange.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, a kind of two flange limit expansion joint, comprises body 1, quincunx gland 2, Limit screw 3, stop nut 4, position limit cycle 5, limit telescopic pipe 6 and hex head bolt 7; The two end part of described body 1 are respectively equipped with the first flange 8 and the second flange 9, and described quincunx gland 2 is located on body 1, and quincunx gland 2 is connected by hex head bolt 7 with the first flange 8; Described position limit cycle 5 is sheathed on body 1, described Limit screw 4 is arranged on position limit cycle 5 by the through hole on quincunx gland 1, one end of Limit screw 3 is connected with the first flange 8, its the other end is provided with stop nut 4 in the side near quincunx gland 2, and its other end is provided with limit telescopic pipe 6 in the side near the second flange 9.
Described limit telescopic pipe 6 and stop nut 4 are located at the both sides of position limit cycle 5 respectively.The described end being arranged on the hex head bolt 7 on quincunx gland 2 is provided with nut.
Expansion joint of the present invention is applicable to both sides all and Flange joint, the connecting length of product two ends and flange is adjusted during installation, gland bolt is evenly tightened successively in diagonal angle, adjust stop nut again, so just can allow pipeline can free-extension within the scope of extending amount, locking stretching amount, guarantees the safe operation of pipeline.Two flange limit expansion joint can prevent pipeline from causing leakage and the damage of compensating joint because of excess displacement, is mainly used in permission displacement range, absorb axial displacement and is connected with the pipeline pine cover bearing axial pressure thrust.Expansion joint structure of the present invention is simple, easy for installation, intensity is large, resistance toly to press, shake little, using effect good, long service life.
