Abstract
The utility model discloses a reducing expansion joint with double loose joints, which consists of a small loose joint, a movable tube, an outer sleeve and a big loose joint. The movable tube is placed inside the outer sleeve; and one end of the movable tube is provided with two grooves. The reducing expansion joint with double loose joints can be used for compensating axial displacement, rotation and a certain quantity of deflection and eccentricity of a pipeline, so that equipment, such as a valve, is protected and is prevented from being cracked or damaged; the reducing expansion joint with double loose joints has the characteristics of flexibility and convenience for disassembly and reducing capacity; and the reducing expansion joint with double loose joints has a double-sealing effect and good sealing performance.
Description
Technical field
The utility model relates to a kind of double loose joints reducing telescopic joint.
Background technique
In pipelayer's journey; usually because the mechanical vibration of equipment; the reasons such as temperature cause axial displacement and a certain amount of deflection and the bias of pipeline; cause device damage and pipe bending; during such as installation plastic rotor flowmeter, be rigidly connected because two ends are, rotameter is easy to break; when equipment is connected with pipeline, often have pipeline reducing diameter.Therefore need a kind of flexible dismounting, expansion joint that can reducing.
The model utility content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art; a kind of pipeline assembly of double loose joints reducing telescopic joint is provided; can compensate axial displacement, rotation and a certain amount of deflection and the bias of pipeline; thereby the equipment such as protection valve; damage prevents from breaking; have dismounting flexible, can reducing and flexible characteristics.
The purpose of this utility model is achieved through the following technical solutions: a kind of double loose joints reducing telescopic joint, formed by little union, adjustable pipe, outer sleeve and large union, and adjustable pipe is placed on outer sleeve inside, and an end of described adjustable pipe is provided with two grooves.
Described little union is provided with little union internal thread.
Described outer sleeve is provided with the outer sleeve outside thread.
Further, described large union is provided with large union internal thread.
Structural principle of the present utility model: adjustable pipe has the externally threaded end of adjustable pipe and passes outer sleeve, the first "O"-ring and the second "O"-ring are stuck in two grooves of adjustable pipe, has dual sealing functions, adjustable pipe can be axially in outer sleeve and rotary moveable, and "O"-ring adopts the EPDM material; Little union is arranged on the adjustable pipe male end, is used for connecting less pipeline or equipment; Large union is arranged on the outer sleeve male end, is used for connecting larger pipeline or equipment.
In sum, the utility model has the advantages that: (1) double loose joints reducing telescopic joint can compensate axial displacement, rotation and a certain amount of deflection and the bias of pipeline, thus the equipment such as protection valve, and damage prevents from breaking; (2) has a dismounting flexible, characteristics that can reducing; (3) has double seal, good airproof performance.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited only to this.
Embodiment:
As shown in drawings, a kind of double loose joints reducing telescopic joint is comprised of little union 1, adjustable pipe 4, outer sleeve 7 and large union 10, and adjustable pipe 4 is placed on outer sleeve 7 inside, and an end of described adjustable pipe 4 is provided with two grooves.
Described little union 1 is provided with little union internal thread 2.
Described outer sleeve 7 is provided with outer sleeve outside thread 8.
Further, described large union 10 is provided with large union internal thread 9.
The end that adjustable pipe 4 has adjustable pipe outside thread 3 passes outer sleeve 7, the first "O"-ring 5 and the second "O"-ring 6 are stuck in two grooves of adjustable pipe 4, have dual sealing functions, good airproof performance, adjustable pipe 4 can be axially in overcoat 7 pipe and rotary moveable; Little union 1 is arranged on adjustable pipe outside thread 3 ends, is used for connecting less pipeline or equipment; Large union 10 is arranged on outer sleeve outside thread 8 ends, is used for connecting larger pipeline or equipment.
The large union nominal diameter D1 of this double loose joints reducing telescopic joint is than the large specification of little union nominal diameter D2.For example: D1=DN25mm, D2=DN20mm; D1=DN50mm, D2=DN40mm, by that analogy, can have flexible and reducing function simultaneously.
As mentioned above, just can realize preferably the utility model.
