Abstract
The invention discloses an elastic bulkhead penetration piece for a high-temperature pipeline, and belongs to the technical field of pipeline vibration noise control. The bulkhead penetration piece comprises a welding flange, an inner pipe, a metal corrugated pipe and a threaded flange, the outer circumference of the inner pipe is provided with two radial limiting bosses, a threaded section is machined at the position, at one end, of the outer circumference, and the threaded section starts from the end face of the inner pipe and ends on the step faces of the limiting bosses; the appearance of the metal corrugated pipe is of a spindle-shaped structure, and the inner circumference and the outer circumference of the position where the diameter is maximum are of a plane structure; the two ends of the metal corrugated pipe are welded to the opposite step faces of the two limiting bosses of the inner pipe, one end of the inner pipe is welded to the welding flange, the other end of the inner pipe is connected with the threaded flange through threads, and the position, where the diameter is maximum, of the metal corrugated pipe is welded to a through hole of a bulkhead. The elastic bulkhead piece can solve the vibration isolation problem of bulkhead penetration of the high-temperature pipeline, and meanwhile the requirements for strength, sealing performance, reliability and the like of the bulkhead can be met.
Description
Technical field
The present invention relates to marine pipeline annex, particularly relate to a kind of elasticity crossing cabin part being applied to shipbuilding field, belong to pipeline vibration noise control technique field.
Background technique
For large ship, in system pipeline, there is a large amount of High Temperature High Pressure pipeline, pipeline through bulkhead, deck or cabin cabinet time, in order to keep the maintenance of the intensity of bulkhead, sealing, high temperature high voltage resistant and pipeline, usually adopt the mode of crossing cabin part.Due to the hot properties of High Temperature High Pressure pipeline, common damping material at this temperature heat ageing speed is accelerated, and intensity sharply declines, and cannot adapt to hot properties requirement, therefore pipeline can only by crossing cabin part rigid solder on bulkhead when crossing cabin, and crossing cabin part two ends connect High Temperature High Pressure pipeline.The impulse excitation of this kind of Placement structural pipe wall vibration and flowing medium can be passed to bulkhead, in addition, pipeline all connects machinery, and machinery itself vibrates also can be delivered to bulkhead by the pipeline be connected with bulkhead, has a negative impact to the vibration and noise reducing of boats and ships.
As can be seen here, current high temperature conduit crossing cabin mode better solves structural pipe wall vibration and flowing medium is pulsed to bulkhead problem of transmission, lack a kind of vibration isolation requirement that can meet High Temperature High Pressure pipeline, the elasticity crossing cabin part of the intensity of bulkhead, sealing, reliability requirements can be met again.
Summary of the invention
The invention provides a kind of high temperature conduit elasticity crossing cabin part, the vibration isolation problems of high temperature conduit crossing cabin can be solved, intensity, sealing, the reliability requirements of bulkhead can be met again simultaneously.
A kind of high temperature conduit elasticity crossing cabin part, comprises welded flange, interior pipe, metal bellows and screwed flange;
The outer peripheral surface of described interior pipe is provided with two radial positive stop lug boss, and the outer peripheral surface of one end is processed with thread section, and thread section arises from the end face of interior pipe, terminates in the step surface of positive stop lug boss;
The profile of described metal bellows is spindle-type α-Fe2O3, and the inside and outside circle side face at largest diameter place is plane structure;
Its integrated connection closes: the two ends of metal bellows are welded on the relative step surface of interior pipe two limited steps respectively, one end of interior pipe is welded with welded flange, the other end is threaded with screwed flange, and the largest diameter place of metal bellows welds with the via hole of bulkhead.
Further, in order to ensure the reliability that screwed flange is connected with Internal Pipe Thread, its screw thread coordinated adopts trapezoidal thread;
Further, in order to ensure the weld strength of crossing cabin part, also comprise a welding ring, the inside and outside circle side face of welding ring welds with the largest diameter place of metal bellows and the via hole of bulkhead respectively.
Beneficial effect:
1. being rigidly connected of ship high temperature pipeline and bulkhead is become elasticity and is connected by high temperature conduit of the present invention elasticity crossing cabin part, its anti-vibration performance is better than traditional pipe-line system crossing cabin part, effectively can isolate the transmission of high temperature conduit vibration noise to bulkhead, improve the vibration and noise reducing performance of boats and ships.
2. have employed metal bellows in pipeline elasticity crossing cabin part of the present invention, the high-temperature stability of metal bellows and anti-vibration performance are fully combined, makes crossing cabin part have good reliability and Security.
3. interior pipe two ends of the present invention connecting welding flange and screwed flange respectively, compact overall structure, easy installation and removal, improve the convenience of workman's construction, maintenance.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of high temperature conduit elasticity of the present invention crossing cabin part.
In figure: pipe, 3-metal bellows, 4-welding ring, 5-screwed flange in 1-welded flange, 2-.
Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1, the invention provides a kind of high temperature conduit elasticity crossing cabin part, a kind of high temperature conduit elasticity crossing cabin part, comprises welded flange 1, interior pipe 2, metal bellows 3, welding ring 4 and screwed flange 5;
The outer peripheral surface of described interior pipe 2 is provided with two radial positive stop lug boss, and the outer peripheral surface of one end is processed with thread section, and thread section arises from the end face of interior pipe 2, terminates in the step surface of positive stop lug boss;
The profile of described metal bellows 3 is spindle-type α-Fe2O3, and the inside and outside circle side face at largest diameter place is plane structure;
Its integrated connection closes: the two ends of metal bellows 3 are welded on the relative step surface of interior pipe 2 two limited steps respectively, one end of interior pipe 2 is welded with welded flange 1, the other end is threaded with screwed flange 5, and the inside and outside circle side face of welding ring 4 welds with the largest diameter place of metal bellows 3 and the via hole of bulkhead respectively.
Further, in order to ensure the reliability that screwed flange 5 is threaded with interior pipe 2, its screw thread coordinated adopts trapezoidal thread;
Working principle: during the work of crossing cabin part, the pressure acting on whole crossing cabin part has flowing pressure and separation pressure in pipe, in pipe, flowing pressure is born by interior pipe 2, welded flange 1 and the screwed flange 5 at interior pipe 2 two ends are with bolts with system pipeline, and with sealing gasket sealing, realize the sealing of interior pipe 2 and system pipeline; Separation pressure is born primarily of metal bellows 3, weld strength between interior pipe 2 and welding ring 4, realizes by the elasticity of metal bellows 3 and resistance to high temperature isolation High Temperature High Pressure pipeline being caused to vibration through bulkhead.
