Abstract
The utility model provides a plastic pipeline compensator, includes a sleeve pipe, a pair of sealing device and a pair of flexible pipe, a pair of flexible pipe is inserted in the sheathed tube both ends of establishing respectively slidable, a pair of sealing device nestification respectively between sleeve and a pair of flexible pipe, this compensator simple structure, sealing performance are good, flexible, can play the compensation under the condition of plastic pipeline expend with heat and contract with cold, guarantee plastic pipeline's safe handling, and use simple to operate, cost are low, have filled the blank in the aspect of domestic plastic pipeline compensator design and manufacturing.
Description
The utility model relates to a kind of compensator, particularly a kind of compensator that is used for plastic lined piping.
As everyone knows, the installation of plastic lined piping is all carried out under room temperature or normal temperature, and the pipeline that is acted upon by temperature changes can elongate or shorten, and its thermal expansion coefficient is 10 times of metallic material.Because the Young's modulus of plastics is very little, if therefore expansive force and contractile force surpass its allowable stress, plastic lined piping will wreck.
The purpose of this utility model just provides a kind of compensator that is used for plastic lined piping, to overcome the damage problem that plastic lined piping causes because of expanding with heat and contract with cold, whenever keeps at a certain distance away in plastic lined piping a compensator is installed, and guarantees the safe handling of plastic lined piping.
The purpose of this utility model realizes by following design:
A kind of plastic lined piping compensator comprises a sleeve pipe, a pair of seal arrangement and a pair of telescopic pipe, and described a pair of telescopic pipe is plugged in respectively in the two ends of described sleeve pipe slidably, and described a pair of seal arrangement is nested in respectively between described tube and a pair of telescopic pipe.
Plastic lined piping compensator structure of the present utility model is simple, good seal performance, flexibly flexible, under the situation that plastic lined piping expands with heat and contract with cold, can play compensating action, guarantee the safety effect of plastic lined piping, and easy to install and use, cost is low, has filled up the blank of domestic plastic lined piping design of Compensator manufacture view.
With reference to the accompanying drawings, the structure characteristic to most preferred embodiment of the present utility model is described further:
Fig. 1 is the structural representation of a kind of plastic lined piping compensator of the present utility model.
Referring to Fig. 1, a kind of plastic lined piping compensator of the present utility model comprises a sleeve pipe 1, this sleeve pipe can by two-part 1 ', 1 " form, a pair of seal arrangement 2,2 ' and a pair of telescopic pipe 3,3 '.Sleeve pipe 1 ', 1 " a relative end have outward flange 4,4 ' and by one group of bolt 5 fixedly connected.Sleeve pipe 1 ', 1 " the middle part have respectively an inside annular projection 6,6 '; a pair of telescopic pipe 3,3 ' respectively be plugged in slidably its corresponding sleeve pipe 1 ', 1 " in, and telescopic pipe 3,3 ' a relative end have respectively two outside annular projections 7,7 ', can be pulled outwardly when extending limit position with sleeve pipe 1 ', 1 " on projection 6,6 ' engage; in order to avoid telescopic pipe 3,3 ' deviate from sleeve pipe 1 ', 1 " and cause the leakage of pipeline, simultaneously, telescopic pipe 3,3 ' the outside end (not shown) that is connected with plastic lined piping respectively.In addition, a pair of seal arrangement 2,2 ' respectively be nested in a pair of sleeve 1 ', 1 " and a pair of telescopic pipe 3,3 ' between; sealing device 2,2 ' respectively comprises a seal ring 8(8 '), a packing ring 9(9 ') and a gland 10(10 '); gland 10(10 ' wherein) be connected with sleeve pipe 1 ' (the other end 11(11 ' of 1 ")), for example fixedly connected with one group of bolt 12, so that regulate sealing by a pair of flange.Seal arrangement 2,2 ' also can only be made of a pair of seal ring.
During use, in the middle of the plastic lined piping that whenever keeps at a certain distance away (being about 20 meters), a compensator can be installed, when the plastic lined piping of two sections connections is heated and extends, telescopic pipe 3,3 ' just in the middle of it in compensator to sleeve pipe 1 ', 1 " in bounce back; and when plastic lined piping is caught a cold contraction; the telescopic pipe 3,3 ' then in the compensator to sleeve pipe 1 ', 1 " outside stretch out, play compensating action.
Claims (3)
1, a kind of plastic lined piping compensator, it is characterized in that, comprise a sleeve pipe, a pair of seal arrangement and a pair of telescopic pipe, described a pair of telescopic pipe is plugged in respectively in the two ends of described sleeve pipe slidably, and described a pair of seal arrangement is nested in respectively between described sleeve pipe and a pair of telescopic pipe.
2, plastic lined piping compensator as claimed in claim 1, it is characterized in that, described sleeve pipe comprises two-part, the relative end of these two-part has outward flange and is bolted to connection, the two-part middle part of described sleeve pipe has an inside annular projection respectively, and the end that described a pair of telescopic pipe is relative has two outside annular projections respectively.
3, plastic lined piping compensator as claimed in claim 1 or 2 is characterized in that, described seal arrangement comprises a seal ring, a packing ring and a gland, and described gland is fixedlyed connected with the other end of described sleeve pipe.
