Abstract
The utility model relates to a pipe thermocompensator, and particularly discloses a spherical compensator. The spherical compensator comprises a shell (1), a spherical pipe (2), a left connecting pipe (3), a right connecting pipe (4), a seal ring (5), a locating ring (6), a sleeve (7) and a gland (8). The spherical compensator is characterized in that an elastic seal ring and a rigid locating ring are arranged between the shell and the spherical pipe, and the spherical pipe can randomly stretch and bend in a certain scope, so as to absorb the heating displacement of pipelines in all directions. The compensator is simple in structure, small in floor area and large in compensation ability, material saving can be realized, and thrust at pipe end cannot be generated, therefore, the extensive application prospect can be realized in industrial and civil heat distribution pipelines, particularly, three-dimensional displacement-based steam and hot water pipelines adopt the compensator optimally, and a working medium can come in and go out at any end.
Description
Technical field
The utility model relates to a kind of pipe thermal compensation device, is specifically related to a kind of spherical compensator.
Background technique
Heat distribution pipeline is because the temperature difference is expanded with heat and contract with cold, the restriction if the amount of expanding with heat and contract with cold suffers restraints, and for example pipe ends is fixed, and pipe interior will produce thermal stress, also claims temperature difference stress.The size of thermal stress is main relevant with the factors such as the temperature difference, material and geometrical shape of pipeline.And most industry production is often all carried out under high temperature or low temperature, pipeline temperature difference stress is quite large.When thermal stress exceeds certain allowable stress range, pipeline will destroy.
Therefore,, for guaranteeing the stable and safe operation of pipeline under hot state or cold state, be necessary to insert the device that can absorb the amount of expanding with heat and contract with cold, i.e. a manual inflation compensator in pipeline.And the stuffing box expansion joint and the corrugated-type expansion joint compensation ability that adopted are little in the past, and can produce compared with bassoon end thrust after compensation.Stuffing box expansion joint again can only absorption axes to heat displacement amount.
Model utility content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of compensation ability of energy extraction duct all directions heat displacement amount to produce greatly and not the spherical compensator of pipe end thrust.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of spherical compensator, comprise housing (1), bulb tube (2), left adapter (3), right adapter (4), seal ring (5), positioning ring (6), sleeve pipe (7), gland (8), is characterized in that being provided with between described housing and bulb tube elastic seal ring and rigidity positioning ring, the relative housing of bulb tube can stretch at random within the specific limits and curve, with the heat displacement amount of extraction duct all directions.
Spherical compensator of the present utility model, described housing (1) left end inner side is set to ring-shaped lug for the axial limiting of left side seal ring (5), and outside is fixedly connected with left adapter (3), and right-hand member is provided with flange ring; Positioning ring (6) is installed in sleeve pipe (7) both sides that housing lumen shaft arranges to middle part, and left and right seal ring is respectively by left and right positioning ring axial limiting.
Described bulb tube (2) right-hand member is fixedly connected with right adapter (4); Bulb tube is placed in housing (1) inner chamber, and bulb tube outer wall two ends are sealed and matched with positioning ring (6) inner ring Spielpassung, seal ring (5) inner ring respectively; Bulb tube outer wall plating 0.04-0.05 millimeters thick hard chrome, makes to rotate not only wear-resisting safety but also flexible.
Described gland (8) and housing (1) right-hand member endoporus Spielpassung, gland connects and compresses right side seal ring (5) with bolt with respect to housing right side.
Described seal ring (5) is outer for adding the teflon material of copper powder, built-in endless metal skeleton.
Compared with prior art, the utlity model has following features and beneficial effect: between described housing and bulb tube, be provided with elastic seal ring and rigidity positioning ring, the relative housing of bulb tube can stretch at random within the specific limits and curve, with the heat displacement amount of extraction duct all directions.This compensator structure is simple, and floor space is little, saves material, compensation ability is large, does not produce pipe end thrust, in industry and civilian heat distribution pipeline, has broad prospect of application, particularly, to the steam of three direction displacement and the most suitable employing of hot water pipeline, working medium can be come in and gone out by any one end.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
With reference to Figure of description 1, the utility model embodiment further describe into:
A kind of spherical compensator, described housing (1) left end is fixedly connected with left adapter (3), described bulb tube (2) right-hand member is fixedly connected with right adapter (4), by described left side seal ring (5), left positioner ring (6), sleeve pipe (7), bulb tube (2), right positioner ring (6), right side seal ring (5) packs housing (1) inner chamber successively into, bulb tube outer wall two ends respectively with positioning ring (6) inner ring Spielpassung, seal ring (5) inner ring is sealed and matched, by described gland (8) and housing (1) right-hand member endoporus Spielpassung, gland connects and compresses right side seal ring (5) with bolt with respect to housing right side.
