Description

Strap clamp layer combined type chimney breast and connector thereof

The utility model belongs to the civilian chimney breast of worker field, relates to a kind of strap clamp layer combined pipeline and connector thereof.

In the prior art, the civilian chimney breast of worker particularly for the chimney of fuel oils such as all kinds of boilers, air-conditioning direct combustion machine, gas-fired equipment smoke evacuation usefulness, is the brick or individual layer iron sheet goods of cement, and the stupid pick of former structure installation period is long, can not change, and shock strength is low; The latter then insulating power is poor, and the easy condensation and dewfall of flue gas influences smoke exhaust efficiency, and is very big to ambient temperature effect when indoor, oxidation and rusting very easily, and, building supporting use with modern city, both all seem very inharmonious, influence the appearance of the city.

The purpose of this utility model provides a kind of strap clamp layer combined type chimney breast and connector thereof, but filling with insulation material is beneficial to insulation in the interlayer; The segmentation combination is installed, adopt V-type hoop formula syndeton, add the ring cover, quick for installation, be convenient to change, need not any on-the-spot welding, and can be according to the supporting requirement of building plans, the selection of material and color can be used as common pipe in addition and are used for the discharging occasion that various needs carry out things such as flue gas, combustion gas, waste gas, micronic dust.

The utility model specific embodiments is as follows:

Pipeline (or pipe fitting, as follows) 1, have double-decker, inwall 3 is arranged, outer wall 5, the two is by the interlayer 4 of the equal equal thickness of leg 8 formation, and its interface end has the flange 2 and the port of inwall 3 to be fixed together; There is indent annular groove 6 at 1 interface position, outer wall 5 tube roads, and this groove has annular brace limit 7 near pipeline 1 interface end one side, and its maximum gauge is less than the maximum gauge of outer wall 5, guarantee that ring cover 13 is installed after, the whole outer surface smoother of pipeline; 8, three to eight of legs are distributed in each 7 inboard, annular brace limit, and are fixed together with the lateral surface of its medial surface and inwall 3 respectively; V-type hoop 9, annular straight flange 10 with symmetry is connected as a single entity, all claim the ground hoop to be enclosed within on the cylindrical of adjacent two pipeline 1 flanges 2, has the opposite opened interface, two to four groups of dismoutability interfaces that symmetry is promptly arranged on its circumference, interface have closure plate 11 and V-type hoop 9 main body end face flat to be fixed together, and symmetrical supporting bolt hole 12 is arranged on the every closure plate 11, two, fastening with bolt and nut; After " V " type openings of sizes of V-type hoop 9 and height will guarantee that it is enclosed within on a pair of flange 2, by locking its opposite opened interface, two hypotenuses of " V " type opening pressed the interior angle 18 of two flange 2 peripheries respectively; Ring cover 13, there is evenly inside circular fold 14 of circumferential edge at two ends, all cover on the interface position of two adjacent channels 1 with claiming, circular fold 14 sticks into respectively in the annular groove 6, the outer surface of its outer surface and outer wall 5 is level and smooth shape, has the single open-type interface, promptly on its circumference, has only one group of dismoutability interface, also can be the opposite opened interface, two to four groups of dismoutability interfaces that symmetry is promptly arranged on its circumference, interface has closure plate 15 and ring cover 13 main body end face flat to be fixed together, 16, two of symmetrical supporting bolts hole are arranged on the every closure plate 15, select with spiral shell, nut is fastening: when pipeline 1 connects, on the sealing surface of flange 2, be coated with fluid sealant 17, packing sealing 17 in annular groove 6.

With above-mentioned same structural principle, also applicable to noncircular cross section pipeline and connector thereof.

As make the vertical pipe type chimney with thin plate, then need add support column in addition or the rope of towing, or according to wall and add fixed mount; As make transverse tube type and then need carriage, or suspension bracket is fixed.

Usefulness of the present utility model is: quick for installation, be convenient to change, do not need any on-the-spot welding, but filling with insulation material in the interlayer 4 can be inserted encapsulant in the annular groove 6, pipeline integral body comprises that interlayer has sealing, heat-insulation and heat-preservation, and outer surface smoother, and can be according to the requirement of building plans bowl cover, the selection of material and color, the scope of application is wide.
