Description
Technical field
The invention belongs to expansion joint technical field, be specifically related to a kind of T-shaped straight-through type pressure balanced expansion joint flexibly connecting that has.
Background technique
Metal corrugated pipe expansion joint is that be heated in modern times pipe network and equipment carries out one of critical component of thermal compensation, has the effect of bit shift compensation, vibration and noise reducing and sealing; Be widely used at present on the equipment such as heating pipeline, craft piping, machine, pump and pressurized container of each industrial department such as metallurgy, oil refining, petrochemical industry, electric power (thermoelectricity, water power and nuclear power), heat supply network, boats and ships, building, cement, aerospace and machinery.
Fig. 1 is the pipeline schematic diagram with equipment and bellows expansion joint in prior art, and the Axial Thermal displacement that bellows expansion joint is used between canceller 1 and fixed bearing 15 is set between equipment 1 and fixed bearing 15; Work bellows 4 one end of bellows expansion joint are connected with equipment 1 by pipeline, and the other end is connected with fixed bearing 15 by pipeline 2.Due to the structural feature of work bellows itself, in the time having pressure in pipeline, work bellows can produce pressure thrust to the two ends at coupled place, fixed bearing 15 can bear the pressure thrust of work bellows, and can directly act on equipment with the pressure thrust of equipment connection end, when serious, can damage equipment, cause serious consequence.
Summary of the invention
For solving the problems of the technologies described above, the object of the invention is to propose a kind of T-shaped straight-through type pressure balanced expansion joint flexibly connecting that has.
The present invention adopts following technological scheme for completing above-mentioned purpose:
Have the T-shaped straight-through type pressure balanced expansion joint flexibly connecting, work bellows one end of described expansion joint is by pipeline and equipment connection, and the other end is connected with fixed bearing by pipeline; Between work bellows and fixed bearing, balance bellows is set; Described balance bellows is communicated with and vertical setting with work bellows; Be provided with articulated link mechanism; Described articulated link mechanism includes hinge plate I, hinge plate II, connecting plate and pulley assembly; The middle part of described connecting plate is fixed on pipeline by seat board, and the two ends of connecting plate are hinged with hinge plate I, hinge plate II respectively; Connecting firmly on the pipeline between work bellows and equipment of hinge plate I; Described hinge plate II arranges perpendicular to hinge plate I, hinge plate II connect firmly the end at balance bellows; Described pulley assembly includes wire rope and pulley; One end of described wire rope is connected with hinge plate I, and the other end of wire rope is walked around pulley and is connected with hinge plate II; The length of cable being connected with hinge plate I is perpendicular to the length of cable being connected with hinge plate II; Angle between angle between elongation line and the connecting plate of described hinge plate I, elongation line and the connecting plate of described hinge plate II equates and is 45 °; In the time that pipeline internal medium has pressure, work bellows and balance bellows produce identical pressure thrust separately simultaneously, and the pressure thrust of work bellows and balance bellows is that bellows equivalent area and pipeline internal medium pressure are long-pending; Articulated link mechanism is set on pipeline, rotate transmission of pressure thrust by lever, band movable pulley component motion, the pressure thrust can complete equilibrium work bellows producing, avoid making equipment to bear the pressure thrust of work bellows, reduce the stressed of pipeline and support; In addition, in the time having temperature in pipeline, work bellows can absorb the thermal stretching amount of pipeline between work bellows and equipment; Like this, can realize work bellows expansion joint axially or compensation ability, can guarantee again pressure thrust that work bellows produces do not act on its connection device on, thereby the Security that improves equipment.
The present invention proposes a kind ofly has a T-shaped straight-through type pressure balanced expansion joint flexibly connecting, balance bellows is set on pipeline, and articulated link mechanism and pulley assembly be set on pipeline, the pressure thrust equivalence that utilizes mechanics lever principle that work bellows is produced equipment passes to balance bellows, has eliminated the pressure thrust suffered with work bellows coupling end equipment; Avoid, because equipment bears the device damage that the pressure thrust of work bellows causes, having reduced the stressed of pipeline and support; In addition, the present invention also can be set to external pressure or interior laminated structure according to dielectric property or compensation ability, and the structure that two groups of work bellowss also can be set is carried out compensate for lateral displacement, further optimizes pipeline and arranges, cost-saving.
