Abstract
The invention provides a rotary compensator which comprises a shell, an inner pipe, a reducing pipe and a gland. The inner pipe is coaxially sleeved with the shell. The left end of the shell and the reducing pipe are connected to a whole, and the right end of the shell is connected with a flange plate. A first boss is arranged on the inner wall of the shell. A second boss is arranged on the outer wall of the inner pipe. The inner wall of the first boss is closely attached to the outer wall of the inner pipe. The end face, matched with the inner pipe, of the shell of the rotary compensator is of a hard conical surface sealing structure. The rotary compensator is simple in structure and easy to manufacture, and is of a structure with taper shafts and taper holes with the same taper matched, and centering and self-compensating functions are achieved. A sealing pair rotates in a stable environment, and it is achieved that the combination face is free of different abrasions, so that the conical surface sealing structure achieves the maintenance-free function. A conventional shaft seal is arranged between the inner pipe and a sealing seat, the conical surface sealing structure is compact and reasonable and good in sealing effect, and the complete sealing performance can be kept for a long time.
Description
Technical field
The present invention relates to compensator technical field, particularly relate to a kind of whirl compensator.
Background technique
The heat distribution pipeline of delivering vapor because built-in medium temperature is high, pressure large, therefore the thermal distortion produced than regular industrial pipe network and blind plate thrust many greatly.The professional workforce being engaged in thermal technology all knows, the blind plate thrust produced when heat distribution pipeline runs has very strong destructiveness, according to safety specification at heat distribution pipeline interdependent node place configuring pipes compensation device and support, to absorb or to compensate thermal distortion.Under prior art condition, the configurable pipe line compensating device of the heat distribution pipeline of delivering vapor has various structures pattern, and the evidence of market sale achievement in recent years combination property is it is preferred that whirl compensator.The obvious structure characteristic of whirl compensator is that to import and export pipeline be equal coupling pipe, and thickness of pipe wall is by the accessible setting of pressure-bearing grade, and two ends pipeline can rotate relatively, the most important thing is to move towards matched group synthesis joint connection structure according to heat distribution pipeline.The degrees of freedom of rotary other structure compensation device of joint connection structural rate is large, compensation rate is larger, displacement is more flexible.In view of said structure advantage, whirl compensator is just widely applied in the heat distribution pipeline of delivering vapor.Although current commercial goods whirl compensator brand is different, specification not etc., 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, and one is that transmission medium temperature is greater than sealability when 150 DEG C and design pressure are greater than 6MPa and significantly declines; Two is may there is fault by the sealing seat of welding forming, there is potential safety hazard when running under high temperature and high pressure condition.
Summary of the invention
The technical problem to be solved in the present invention is: do not add to solve whirl compensator sealability of the prior art, runs the problem that there is potential safety hazard, the invention provides a kind of whirl compensator and solve the problems referred to above under high temperature and high pressure condition.
The technical solution adopted for the present invention to solve the technical problems is: a kind of whirl compensator, comprise shell, interior pipe, reducer pipe and gland, described shell coaxial sleeve is located at outside described interior pipe, left end and the described reducer pipe of described shell are connected as a single entity, right-hand member is connected with flange plate, the inwall of described shell has the first boss, the outer wall of described interior pipe has the second boss, the inwall of described first boss and the outer wall of described interior pipe 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 right flank of described first boss and the inwall of described shell form seam, in described seam, plug is equipped with filler, the right side of described filler is provided with seal ring, described gland is fixedly connected with described flange plate by multiple axial nut, and described gland leans on described seal ring, described shell circumferentially offers 4 ~ 20 radial direction through hole, on described shell, corresponding each described radial direction through hole is also fixed with 4 ~ 20 filler pipes, described filler pipe is communicated with radial direction through hole, the end of described filler pipe is provided with plug screw.
As preferably, described first conical surface is identical with the tapering of second conical surface, is 60 ° ~ 90 °.
As preferably, the outer wall of described interior pipe is coated with one deck 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 Expanded graphite.
The invention has the beneficial effects as follows, the end face that this whirl compensator shell matches with interior pipe is hard conical surface sealing structure, structure is simple, making is easy, that a kind of taper shaft of identical tapering matches with tapered hole structure, there is centering and self-compensating effect, sealing pair rotates under stable environment, accomplish that junction plane indifference is worn and torn, conical surface sealing structure is made to have non-maintaining function, add between interior pipe and sealing seat and be provided with conventional shaft sealing, this kind of conical surface sealing structure is compact, reasonable, and good sealing effect can remain intact sealability for a long time.
