Abstract

The utility model relates to a double layered, thermal insulation and rain-proof type chimney which comprises an inner layer cylinder which consists of an inner layer cylinder 1 and inner layer cylinder 2; at least one end of the inner layer cylinder has a flange, while at least one end of the inner layer cylinder 2 has an groove type flange which is fastened with the flange; an outer socket cylinder is formed of a plurality of outer layer cylinder 1 and outer layer cylinder 2; at least one tail wall of the outer layer cylinder 1 has a ring-shaped inward groove, and at least one tail wall of the outer layer cylinder 2 has a ring-shaped double groove; a ring lathe dog is inserted in the inward groove of an inner socket cylinder 1 and the outer layer cylinder 2; a supporting ring and an thermal insulating layer are arranged between the inner socket cylinder and the outer socket cylinder; the chimney has favorable thermal insulating performance and can be dismounted and also can guard against rain.

Description

A kind of double-layer heat insulation rain-proof type chimney

Technical field

The utility model relates to a kind of double-layer heat insulation rain-proof type chimney.

Background technology

At present, existing chimney is most of, and the former insulating power is poor for individual layer iron sheet or cement are built into, the easy condensation and dewfall of flue gas, and the stupid pick of latter's structure, installation period is long, can not change, and therefore, is necessary to provide a kind of novel chimney.

Summary of the invention

The purpose of this utility model provides a kind of double-layer heat insulation rain-proof type chimney, and this chimney is good heat insulating not only, can change, and can prevent that again rainwater infiltrates.

For achieving the above object, the utility model is taked following design scheme: this double-layer heat insulation rain-proof type chimney, it comprises: the internal layer tube that many groups are made up of internal layer tube I, internal layer tube II, described internal layer tube I has at least an end that one flange is arranged, internal layer tube II has at least an end that one groove shaped flange is arranged, and flange and groove shaped flange interlock; The outer sleeve that many groups are made up of outer tube I, outer tube II, described outer tube I has at least inwardly groove of an annular is arranged on the rear wall, outer tube II has at least an annular dual-cavity is arranged on the rear wall, one concaves in the dual-cavity, one outside recessed, on the inside groove of outer sleeve I, outer tube II, insert a ring clip, support ring and insulation layer are arranged between inner sleeve and outer sleeve.

Advantage of the present utility model: good heat insulating, compact conformation, processing, easy to use, because an outer tube II has dual-cavity, thereby the rainwater that oozes under the cooperation place, top, can drop down onto outside the pipe along the water storage mouth of groove.

The specific embodiment

As shown in Figure 1,1 is internal layer tube I, 4 is internal layer tube II, there is a flange internal layer tube I end, and there is a groove shaped flange end of internal layer tube II, and internal layer tube I, internal layer tube II buckle into flange that mode cooperates in the groove of flange, 2 is outer tube I, 7 is outer tube II, and inwardly groove of annular is arranged on its ectomesoderm tube I rear wall, on the outer wall of outer tube II an annular dual-cavity is arranged; One of them is outwards recessed, one concave, in the groove that inside groove and the outer tube II of outer tube I concave, insert ring clip 3, between internal layer tube and outer tube, support ring 5 is arranged, and between internal layer tube and outer tube, be placed with heat insulating material, and become insulation layer 10, a water storage mouth 6 is arranged among the figure, pass through hoop junction plate 11 at ring clip 3, so that its clamping.

Can have a plurality of screws 9 that hold out against to hold out against on the flange that above-mentioned internal layer tube I, internal layer tube II are interlocked, each holds out against screw and U-shaped pressure strip 8 with threaded engagement.

This chimney is made up of a plurality of internal layer tubes, outer tube, and each internal layer tube is made up of an internal layer tube I, internal layer tube II, and each outer tube is made up of an outer tube I, outer tube II.If all there is flange at internal layer tube I both ends, the both ends structure of internal layer tube II is the groove shaped flange so.Also can be that end of internal layer tube I is that end of groove shaped flange is for being flange.As for outer tube I and outer tube II tail structure, can be two afterbody same structures equally, also can be different structure, cooperatively interact as long as realize.

Claims

1, a kind of double-layer heat insulation rain-proof type chimney, it is characterized in that comprising: the internal layer tube that many groups are made up of internal layer tube I, internal layer tube II, described internal layer tube I has at least an end that one flange is arranged, and internal layer tube II has at least an end that one groove shaped flange is arranged, and flange and groove shaped flange interlock; The outer sleeve that many groups are made up of outer tube I, outer tube II, described outer tube I has at least inwardly groove of an annular is arranged on the rear wall, outer tube II has at least an annular dual-cavity is arranged on the rear wall, in the dual-cavity one concave, one outside recessed, on the inside groove of outer sleeve I, outer tube II, insert a ring clip, support ring and insulation layer are arranged between inner sleeve and outer sleeve.

2, double-layer heat insulation rain-proof type chimney according to claim 1 is characterized in that: have a plurality of screws that hold out against to hold out against on the flange that described internal layer tube I, internal layer tube II interlock, each holds out against spiral shell and pressure strip with the threaded engagement U-shaped.
