Description
Technical field
The utility model relates to a kind of sleeve compensator.Thermal expansion for eliminating concentrated supply of heating in the city pipeline is flexible and reverse.
Background technique
Concentrated supply of heating in the city is exactly from city central heat source, and with steam or hot water for medium, supply life and productions is hot through heating network to the user in the whole city or wherein a certain area, also claiming district heating, is an Infrastructure of urban energy construction.Due to heat supply pipeline because steam or hot water circulation can make the factors such as the error in pipeline heat expansion and installation process, can cause pipeline extension and torsion, serious meeting makes pipeline arch upward, breaks, and causes huge personal injury and loss.
Before the utility model is made, normally increase bellows or material filling type compensator (as shown in Figure 1, Figure 2) in the duct, the thermal expansion eliminating pipeline by the free-extension that is flexible or material filling type compensator of bellows is flexible and reverse.But bellows easily ftractures, working life is shorter, and material filling type compensator needs regular replenishment filler, and therefore these two kinds of forms all need to increase maintenance well in underground situations in pipes, add engineering cost and also add maintenance cost simultaneously.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of concentrated supply of heating in the city pipe sleeve compensator can eliminated thermal expansion of pipeline and stretch and can be non-maintaining.
The purpose of this utility model is achieved in that a kind of concentrated supply of heating in the city pipe sleeve compensator, comprise adjustable pipe assembly, fixed tube assembly and positioning component, adjustable pipe assembly left end is connected with under ground piping, and it is freely movable that right-hand member is plugged in fixed tube assembly; Fixed tube assembly right-hand member and anchor block directly, arrange a groove in fixed tube assembly inner edge, are equipped with axle Y in groove
xshape seal ring, formation first seals, and twice the one O type circle is increased on this groove left side, formation second seals, described positioning component is arranged on adjustable pipe assembly outer rim, arranges a step in addition in adjustable pipe assembly left side outer rim, and positioning component left end is arranged to " ┏ " type draw ring structure, and set up the 2nd O type circle in " ┏ " type draw ring inner edge, form three seals.
The utility model concentrated supply of heating in the city pipe sleeve compensator, between twice the one O type circle, direct back-up ring separates.
The utility model concentrated supply of heating in the city pipe sleeve compensator, the L-type flange on positioning component is connected with stud and nut with between the flange on fixed tube assembly,
The beneficial effects of the utility model are:
The utility model by arranging axle Y between fixed tube assembly and adjustable pipe assembly
xshape seal ring, comes the gap between air-tight movable pipe assembly and fixed tube assembly with pressure own in pipeline, makes to ensure when mutually sliding both it not reveal.And at axle Y
xthe shape seal ring left side increases twice the one O type circle, directly separates with teflon back-up ring between twice the one O type circle, and by setting up the 2nd O type circle in positioning component inner edge, in order to keep out underground sediment, prevents silt from flowing into sleeve compensator primary seal (axle Y
xshape seal ring), damage axle Y
xshape seal ring.
Utility model works performance safety is reliable, long service life, freedom from repairs, exempts to establish underground to keep in repair well, and also without the need to increasing filler etc., reliability is high, good economy performance.Reduce pipe-line construction cost simultaneously.Decrease engineering cost.

Embodiment
See Fig. 3 ~ 4, Fig. 3 is the utility model concentrated supply of heating in the city pipe sleeve compensator structure schematic diagram.Fig. 4 is II enlarged view of Fig. 3.As can be seen from Fig. 3 and Fig. 4, the utility model concentrated supply of heating in the city pipe sleeve compensator, comprise adjustable pipe assembly 1, fixed tube assembly 5 and positioning component 2, adjustable pipe assembly 1 left end is connected with under ground piping, it is freely movable that right-hand member is plugged in fixed tube assembly 5, fixed tube assembly 5 right-hand member and anchor block directly, arrange a groove in fixed tube assembly 5 inner edge, are equipped with axle Y in groove
xshape seal ring 4, forms first sealing, comes the gap between air-tight movable pipe assembly and fixed tube assembly.And twice the one O type circle 3 is increased on this groove left side, make it form second sealing, and directly separate with back-up ring 9 between twice the one O type circle 3, prevent adhesion between two the one O type circles 3 to lose efficacy.Positioning component 2 is arranged on adjustable pipe assembly 1 outer rim, L-type flange on positioning component 2 is connected with stud 6 and nut 7 with between the flange on fixed tube assembly 5, stud 6 and nut 7 extrude twice the one O type circle 3, increase sealing effect, positioning component 2 prevents pipe laying from meeting cold events, sleeve compensator is caused to come off, in addition a step is set in adjustable pipe assembly 1 left side outer rim, positioning component 2 left end is arranged to " ┏ " type draw ring structure, thus serve anti-slip effect, and set up the 2nd O type circle 8 in " ┏ " type draw ring inner edge, form three seals, in order to keep out underground sediment, prevent silt from flowing into sleeve compensator primary seal (axle Y
xshape seal ring 4), damage axle Y
xshape seal ring 4, increases the working life of gasket seal.Thus ensure the stability of sleeve expansion joint in heat supply pipeline uses.
