Description

Whirl compensator

Technical field

This utility model relates to compensator technical field, particularly relates to a kind of whirl compensator。

Background technology

The heat distribution pipeline of conveying steam is big because of built-in medium temperature height, pressure, therefore more many greatly than the thermal deformation of regular industrial pipe network generation and blind plate thrust。The professional being engaged in thermal technology all knows, the blind plate thrust produced when heat distribution pipeline runs has very strong destructiveness, according to safety code at heat distribution pipeline interdependent node place configuring pipes compensation device and support, to absorb or to compensate thermal deformation。The configurable pipe line compensating device of heat distribution pipeline carrying steam when prior art has various structures pattern, the evidence combination property most preferably whirl compensator of market sale achievement in recent years。It is equal coupling pipe that the obvious architectural feature of whirl compensator is into and out mouthful pipeline, and thickness of pipe wall presses the accessible setting of pressure-bearing grade, and two ends pipeline can rotate against, it is most important that can move towards matched group synthesis joint connection structure according to heat distribution pipeline。Rotary joint connection structure is bigger than the degree of freedom of other structure compensation device, compensation dosage is bigger, displacement is more flexible。In view of said structure advantage, whirl compensator is just widely applied in the heat distribution pipeline of conveying steam。Although current commercial goods whirl compensator brand is different, specification not etc., but basic structure is identical, meets the supporting requirement of heat distribution pipeline all to some extent。, it is not enough that the whirl compensator of prior art also exposes two aspects in the application, one be transmission medium temperature more than 150 DEG C and design pressure more than 6MPa time sealing property be remarkably decreased；Two is that seal receptacle by welding forming would be likely to occur fault, there is potential safety hazard when running under high temperature and high pressure condition。

Utility model content

The technical problems to be solved in the utility model is: be not added with to solve whirl compensator sealing property of the prior art, runs the problem that there is potential safety hazard under high temperature and high pressure condition, and this utility model provides a kind of whirl compensator to solve the problems referred to above。

This utility model solves its technical problem and be the technical scheme is that a kind of whirl compensator, including shell, interior pipe, reducer pipe and gland, described shell coaxial sleeve is located at outside said inner tube, the left end of described shell and described reducer pipe are connected as a single entity, right-hand member is connected to ring flange, the inwall of described shell has the first boss, the outer wall of said inner tube has the second boss, the described inwall of the first boss and the outer wall of said inner tube fit tightly, the left surface of described first boss is first conical surface, the outer wall of described second boss and the inwall of described shell fit tightly, the right flank of described second boss is second conical surface, described first conical surface and second conical surface fit tightly and are provided with anti-vibration ring between them, the inwall of the right flank of described first boss and described shell forms seam, described seam is filled in equipped with filler, the right side of described filler is provided with sealing ring, described gland is connected by multiple axial nut and described ring flange are fixing, and described gland acts against on described sealing ring, described shell circumferentially offers 4 ~ 20 radial direction through hole, on described shell, corresponding each described radial direction through hole is further fixed on 4 ~ 20 filler pipes, described filler pipe connects with radial direction through hole, the end of described filler pipe is provided with plug screw。

As preferably, the tapering of described first conical surface and second conical surface is identical, is 60 ° ~ 90 °。

As preferably, the outer wall of said inner tube being coated with one layer of Cr, the thickness of coating is 0.02 ~ 0.04mm。

As preferably, described filler is graphite, and the material of described anti-vibration ring is soft graphite。

The beneficial effects of the utility model are, the end face that this whirl compensator shell matches with interior pipe is hard conical surface sealing structure, simple in construction, making are easily, it is that the taper shaft of a kind of identical tapering matches with tapered hole structure, there is centering and self-compensating effect, sealing pair rotates under stable environment, accomplish that faying face indifference is worn and torn, conical surface sealing structure is made to have non-maintaining function, add and between interior pipe and seal receptacle, be provided with conventional shaft sealing, this kind of conical surface sealing structure is compact, reasonable, good sealing effect, it is possible to remain intact sealing property for a long time。
