Description

A kind of bend pipe displacement compensation device of high-temperature pipe
Technical field
The present invention relates to a kind of compensation devices, and in particular to a kind of bend pipe displacement compensation device of high-temperature pipe.
Background technology
Electricity Federation production has energy saving, improvement environment, improves heating quality, increases the comprehensive benefits such as supply of electric power.Thermoelectricity The construction of factory is Urban Governance atmosphere pollution and improves the important measures of energy utilization rate, is the important composition portion of central heating Point, it is the public welfare infrastructure for improving people's living standard.Since reform and opening-up, China's cogeneration of heat and power cause has obtained rapidly Development, to promoting national economy and social development to play important function.However in numerous Cogeneration Projects, heat conveying is The important link of influence project whole efficiency.In recent years, more and more distributed energy resource systems relied on energy delivery system.Institute Need fed distance also increasingly remoter, especially the Northwest in China, pipe design are particularly important.
The thermal compensation of heat supply pipeline is a critically important technology, and pipe expansion is that heat distribution pipe network safe design is considered 's.When temperature forms graded, pipeline can expand larger displacement, it is necessary to consider that enough displacements can just prevent pipeline from damaging Bad accident occurs.Bellows can easily be bent, elongate, Ya Shrink, therefore is widely used in piping connection, with to pipe Road carries out bit shift compensation.But pipe bent position is because turbulent-flow heat-exchanging amount is big, and the temperature difference is big, and practical pipeline needs volume in the swell increment of pipe bent position Outer attention.
Invention content
The present invention to solve the above-mentioned problems, to provide a kind of bend pipe displacement compensation device of high-temperature pipe.
In order to achieve the above objectives, technical scheme is as follows:
A kind of bend pipe displacement compensation device of high-temperature pipe, bend pipe displacement compensation device include two low level bellowss, one A high position bellows, the first pull rod and the second pull rod, two low level bellowss are symmetrical arranged, and the high position bellows is respectively with two The upper surface of a low level bellows one end connects, and is higher than the two low level bellowss, the high position at the top of the high position bellows Ripple bottom of the tube maintains an equal level with the two low level bellowss, and each low level bellows is equipped with ripple, each low level bellows side Equipped with flange, first pull rod is separately connected the flange of both sides, and is connect with the upper surface of each low level bellows, and described Two pull rods are separately connected the flange of both sides, and are connect with the lower surface of high-order bellows.
In a preferred embodiment of the invention, the low level bellows is circle.
In a preferred embodiment of the invention, the ripple is the corrugation lobes around low level ripple tube edges.
In a preferred embodiment of the invention, the ripple is made of austenitic stainless steel material, multiple diaphragms Outer rim is acted as to heap base one and is welded to form bellows segment.
The beneficial effects of the invention are as follows:
The present invention compensates for the displacement that elbow is generated by temperature, ensures protection of the temperature change to pipeline bending part, compares Remaining rectangle temperature compensator, simple in structure but safety and reliability.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with Obtain other attached drawings according to these attached drawings.
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the side view of the present invention;
Fig. 3 is the vertical view under present invention bending situation.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below Conjunction is specifically illustrating, and the present invention is further explained.
Referring to Fig. 1 and Fig. 3, the bend pipe displacement compensation device of high-temperature pipe provided by the invention comprising two low level waves The high-order bellows 4 of line pipe 2, two, the first pull rod 3 and the second pull rod 5.
Two 2 mutual horizontal symmetrical of low level bellows settings, flange 5, low level are welded in each 2 side of low level bellows Bellows 2 by flange 5 is used to that, to having the technically demanding various pumps of displacement, vibration, valve to connect, axis can be made to the device Compensation to, lateral both direction.
Low level bellows 2 is circle, and ripple 6 is equipped on low level bellows 2, and ripple 6 is specially around low level bellows 2 The corrugation lobes at edge specifically use austenitic stainless steel material or select other materials to be made according to actual demand, have There is an excellent flexibility, corrosion resistance, heat-resisting quantity (- 235 DEG C~+450 DEG C), barotolerance (up to 32MPa) can be Any direction can be attached in low level bellows 2, to temperature-compensating and absorb vibration, reduction noise, change medium Conveying direction, the mechanical displacement etc. for eliminating pipeline enclosure or pipeline and equipment room.
First pull rod 3 is separately connected the flange 1 of both sides, and is connect with the upper surface of each low level bellows 2, when having When temperature gradient, two low level bellowss 2 will produce axial displacement, since pipe bent position will produce the bending of certain curvature, and One pull rod 3 can limit 2 bending degree of low level bellows.
High-order bellows 4 is connect with the upper surface of two 2 one end of low level bellows respectively, also, its top is higher than this Two low level bellowss 2, and bottom maintains an equal level with the two low level bellowss 2, is for decomposing stress in low level bellows 2 In the case of, decompose 2 jiaos of phases of low level bellows or remaining direction displacement.
Second pull rod 5, is bending radius proximal end, the flange 1 of difference horizontal connection both sides, and with high-order bellows 4 Lower surface connection.
By the setting of above structure, when generating curvature at low level bellows 2, due to the first pull rod 3 and the second pull rod 5 Limitation, in the upside of high-order bellows 4, i.e., distal end generates angular displacement, and device integrally keeps stable, will not make whole wave Line pipe such as is unlikely to produce fracture at the safety problems.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its Equivalent thereof.
