Abstract
The utility model relates to pipeline thermal compensator products, in particular to a stuffing box type compensator. The stuffing box type compensator comprises a telescopic sleeve (1) and a fixed pipe sleeve (2) and is characterized in that a stuffing box (3) is arranged between the telescopic sleeve (1) and the fixed pipe sleeve (2), and the telescopic sleeve can linearly move in a reciprocating mode relative to the fixed pipe sleeve, so that the axial thermal expansion amount of a pipe is absorbed. The stuffing box type compensator is simple in structure, large in compensation amount, good in sealing performance, capable of enabling stuffing to be replaceable, convenient to install and overhaul, low in manufacturing cost and capable of being widely used in industrial heat distribution pipelines and civil heat distribution pipelines.
Description
Technical field
The utility model relates to a kind of pipe thermal compensation device product, particularly a kind of stuffing box expansion joint.
Background technique
Pipeline or equipment and material expand with heat and contract with cold, the restriction if the amount of expanding with heat and contract with cold suffers restraints, and pipeline or device interior will produce thermal stress, also claim 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 or equipment.And industrial production is usually carried out under high temperature or low temperature, temperature difference stress is quite large.When thermal stress exceeds certain allowable stress range, pipeline or equipment will destroy, impact safety in production.
Therefore,, for guaranteeing the stable and safe operation under hot state or cold state of pipeline or equipment, be necessary to insert the device that can absorb the amount of expanding with heat and contract with cold, i.e. a thermal expansion compensator in pipeline or equipment.
Model utility content
The purpose of this utility model is to provide a kind of stuffing box expansion joint of energy extraction duct thermal expansion amount.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of stuffing box expansion joint, comprise telescopic tube (1), fixing pipe box (2), it is characterized in that at telescopic tube and fixedly between pipe box, be provided with stuffing box (3), telescopic tube can move as reciprocating linear relative to fixing pipe box, with extraction duct axial thermal expansion amount.
Stuffing box expansion joint of the present utility model, described telescopic tube (1) left end is provided with flange plate (4), and right-hand member is provided with support ring (5).
Described fixedly pipe box (2) inside is provided with filler baffle ring (6), and right-hand member is provided with flange plate (7).
Described stuffing box (3) is further set to saturated with motor oil and scribbles the asbestos fake of plumbago, with filler flange (8), press-fits in described telescopic tube, fixedly between pipe box and filler baffle ring.
Compared with prior art, the utlity model has following features and beneficial effect: described telescopic tube (1) and be fixedly provided with stuffing box (3) between pipe box (2), telescopic tube can move as reciprocating linear relative to fixing pipe box, with extraction duct axial thermal expansion amount.This compensator structure is simple, and compensation rate is large, and sealability is better, and filler is replaceable, and installation and repairing is convenient, and cost is low, can be widely used in industry and civilian heat distribution pipeline.
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:
, described telescopic tube (1) left end is fixedly connected with to flange plate (4), right-hand member flange processes support ring (5).By described fixedly pipe box (2) interior welds filler baffle ring (6), right-hand member is fixedly connected with flange plate (7).Described telescopic tube (1) right-hand member is inserted to the fixedly middle appropriate location of pipe box (2), with filler flange (8), stuffing box (3) is press-fited in described telescopic tube, fixedly between pipe box and filler baffle ring.Described telescopic tube right-hand member has support ring, so can not depart from described fixedly pipe box.
Claims (4)
1. a stuffing box expansion joint, comprises telescopic tube (1), and fixedly pipe box (2), is characterized in that at telescopic tube and fixedly between pipe box, be provided with stuffing box (3).
2. stuffing box expansion joint as claimed in claim 1, is characterized in that: described telescopic tube (1) left end is provided with flange plate (4), and right-hand member is provided with support ring (5).
