Abstract
The utility model discloses an air duct compensator, which comprises two sets of suited sleeve and a nonmetallic ring around the joint of above-mentioned sleeve. Heat insulating layer is arranged in the annular cavity shaped by the nonmetallic ring and external surface of two sleeves, which is characterized in that the drain on nonmetallic ring. In addition, the drain is connected with airtight layer of extended drain pipe. Drain pipe besides drain is corrugated flexible pipe. The utility model has the advantages that the nonmetallic ring has drain, which is connected with sealing device of extended drain pipe, thus discharging moisture absorbing on heat insulating layer of compensator, avoiding compensator erosion by acid water and prolonging compensator' s service life.
Description
Technical field
The utility model relates to ingress, absorption tower bore than the compensator of using on the large pipeline, especially relates to a kind of air channel compensator.
Background technique
Be arranged in the non-metal compensator on the big pipeline of ingress, absorption tower bore, because the medium of line transportation is hot blast, hot vapour, in running, thermal-protective coating in the compensator can adsorb moisture in the medium and water of condensation, and the horizontal length of compensator is long and quality is softer, the water of absorption is the acid water after the desulfurization again, so long-time pocket water of compensator, can make compensator bear unnecessary additional load and suffer the erosion of acid water, influence the using effect and the life-span of compensator.
The model utility content
The purpose of this utility model is to provide a kind of air channel compensator that can in time the moisture of absorption be derived outside the compensator.
For achieving the above object, the utility model can be taked following technical proposals:
Air channel described in the utility model compensator, it comprises that part is sleeved on two sleeve pipes together, and stuffing box gland is contained in the nonmetal astragal of described two sleeve pipe outer circumferential face jointings, in the ring cavity that nonmetal astragal and two sleeve pipe outer circumferential faces surround, be provided with thermal-protective coating, it is characterized in that: on described nonmetal astragal, offer drain port, described drain port is communicated with the drain pipe sealing that extension is provided with, and the drain pipe at close drain port place is corrugated flexible pipe.
Described drain pipe is connected on the nonmetal astragal by the inside and outside liner plate consistent with nonmetal astragal radian.
Advantage of the present utility model is to offer drain port on the nonmetal astragal, described drain port is communicated with the drain pipe sealing that extension is provided with, the moisture that is adsorbed on like this on the compensator thermal-protective coating can in time be discharged by drain pipe, avoided the erosion of acid water to compensator, prolonged the working life of compensator, can be set to one or more according to the diameter drain port of pipeline in the use; Drain pipe near the drain port place is corrugated flexible pipe, has guaranteed the proper functioning that neither can influence compensator that moves of drain water piping, can not influence the life-span of compensator again.This kind air channel compensator structure is simple, and drain water piping can be embedded in the wall of absorption tower, also can be according to the field condition setting.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, air channel described in the utility model compensator, it comprises that part is sleeved on two sleeve pipes 1,2 together, and stuffing box gland is contained in the nonmetal astragal 3 of described two sleeve pipes, 1,2 outer circumferential face jointings, is provided with thermal-protective coating 4 in the ring cavity that nonmetal astragal 3 and two sleeve pipes, 1,2 outer circumferential faces surround.Offer drain port 5 on described nonmetal astragal 3, described drain port 5 is communicated with drain pipe 6 sealings that extension is provided with, and the drain pipe 6 at close drain port 5 places is corrugated flexible pipe 7.For drain pipe 6 firmly is connected with nonmetal astragal 3, drain pipe 6 is connected mutually by the inside and outside liner plate 8,9 consistent with nonmetal astragal 3 radians.
