Abstract
The invention discloses a rotating compensator which comprises a rotating cylinder, wherein a gland and a sealing seat are arranged on the outer surface of the rotating cylinder; the gland is arranged at the front end of the sealing seat; a pipe nipple is arranged at the front end of the rotating cylinder. According to the invention, internal pressure thrust is not generated, and a centering problem does not exist, so that supports in different directions are not needed to be additionally arranged, and heat expansion and contraction amount is not reserved during heat insulation, as a result, heat loss is lesser.
Description
Technical field
The present invention relates to a kind of compensator, be specifically related to a kind of whirl compensator.
Background technique
Compensator is applicable to pipeline, be applied to pipeline owing to the telescopic variation of expanding with heat and contract with cold and causing, thereby reduce the stress and the active force that acts on valve member or the supporting structure of tube wall, and all there is problems such as can producing interior pressure thrust in general compensator, cause thermal loss larger, affect real work efficient.
Summary of the invention
Goal of the invention: the present invention provides a kind of whirl compensator in order to solve the deficiencies in the prior art.
Technological scheme: a kind of whirl compensator, comprise rotary drum, the rotary drum outer surface is provided with gland and sealing seat, and gland is arranged on the sealing seat front end, and the rotary drum front end is provided with pipe nipple.
As preferably, be bolted between gland and the sealing seat.
As preferably, the overlapping part between gland and the sealing seat is provided with stuffing box packing.
As preferably, the gland front end is provided with steel ball with the joint of rotary drum.
Beneficial effect: the present invention compares with existing technology, does not produce interior pressure thrust, does not have " in looking for " problem, thereby also needn't additionally increase the purpose support, needn't reserve hot extending amount when insulation, thereby thermal loss is less.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with specific embodiment.
Specific embodiment:
A kind of whirl compensator comprises rotary drum 1, and rotary drum 1 outer surface is provided with gland 2 and sealing seat 3, gland 2 is arranged on sealing seat 3 front ends, rotary drum 1 front end is provided with pipe nipple 4, is bolted between gland 2 and the sealing seat 3, and the overlapping part between gland 2 and the sealing seat 3 is provided with stuffing box packing 5.Gland 2 front ends are provided with steel ball 6 with the joint of rotary drum 1.
The present invention does not produce interior pressure thrust, thereby the fixed support at compensator two ends can do very littlely, does not have " in looking for " problem, thereby needn't additionally increase incorgruous support yet; Needn't reserve hot extending amount when insulation, thereby thermal loss is less, reasonably sealing configuration can guarantee not produce leakage so that the wearing and tearing of sealing material and sealing surface are very slight within the longer time.
