Abstract
The utility model relates to a direct buried type corrugation compensator used for eliminating the pipeline heat expansion of transferring hot fluid, wherein a protective sleeve 3 is arranged at the outer side of a corrugated pipe, one end of the protective sleeve is sealed and welded with a corrugated pipe welding flange 2, and the other end is welded with a baffle ring 8. The baffle ring is provided with a sealing ring pressing cover 11 and a packing pressing cover 14, and a temperature resistant rubber sealing ring 10 and an asbestos packing 12 are arranged in the pressing cover. The contact friction surface of two seals and an expansion joint is a stainless steel sealing barrel 15, and the sealing barrel and the expansion joint 9 are sealed and welded. The corrugated pipe can not be corroded after buried under the ground, and the utility model can compensate heat for a long time.
Description
The utility model relates to a kind of directly buried bellows type expansion joint of carrying hot fluid pipeline thermal expansion that is used to eliminate.
At present, the corrugated expansion joint that the conveying hot fluid pipeline of knowing altogether adopts because of expanding with heat and contract with cold is underground when directly imbedding when being installed in, to implement a concrete Fang Jing in the bellows installation place, corrugated expansion joint is installed in the concrete Fang Jing, prevented that the contoured exterior side that sewage, silt enter corrugated expansion joint from filling up the ripple recess, lost compensating action.The hot fluid pipeline is carried in construction and installation, and not only difficulty of construction is big for additional construction concrete Fang Jing, and investment is high.
The purpose of this utility model provides a kind of directly buried bellows type expansion joint, and it self can prevent that sewage, silt from entering the contoured exterior side of corrugated expansion joint, and the concrete side's well of can constructing is directly imbedded underground, can play the thermal compensation effect muchly.
The purpose of this utility model is to realize like this; in the bellows outside protecting jacket (3) is installed; protecting jacket one end is with bellows welded flange (2) sealing welding; a other end welding baffle ring (8); temperature resistant rubber seal ring (10) [using scope≤150 °] is installed on the baffle ring; seal ring gland (11) and asbestos packing (12) and packing gland (14) are gone up at bellows expansion joint (9) a stainless steel sealing drum (15) sealing drum both sides and the airtight soldering and sealing of expansion joint are installed; when bellows is subjected to force compresses and stretches; asbestos packing and the contact friction on the stainless steel sealing drum of temperature resistant rubber seal ring; to block underground sewage and silt; bellows outside recess is kept clean, can realize the purpose of thermal compensation.
Owing to adopt technique scheme, carry the hot fluid pipeline to adopt the directly buried type ripple to mend
Accompanying drawing is a diagrammatic sketch of the present utility model
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1, be the directly buried bellows type expansion joint erection drawing
Among the figure 1, take over 2, welded flange 3, protecting jacket
4, bellows 5, interior water conservancy diversion cover 6, outer water conservancy diversion cover
7, rotary flange 8, baffle ring 9, expansion joint
10, temperature resistant rubber seal ring 11, seal ring gland
12, asbestos packing 13, bolt 14, packing gland
15, sealing drum 16, press strip
In Fig. 1, adapter (1), welded flange (2), bellows (4), rotary flange (7), expansion joint (9) are welded to each other together, constitute a pressure-tight space and become corrugated expansion joint, when after taking over (1), expansion joint (9) and pipeline welding, carrying hot fluid, just played the thermal compensation effect.Interior water conservancy diversion cover (5), outer water conservancy diversion cover (6) have been the fluid flow guiding effects, and the flow direction that corrugated expansion joint will be noted hot fluid is installed, and be consistent with the product external standard direction of arrow.(2) protecting jacket (3) of burn-oning on welded flange, the protecting jacket the other end baffle ring (8) of mantle fiber of holing in advance of burn-oning is installed in sealing gland (11), temperature resistant rubber seal ring (10) and packing gland (14), asbestos packing (12) on the baffle ring with several bolts (13); At expansion joint (a 9) stainless steel sealing drum of upper sleeve through (15), sealing drum one end and rotary flange (7) welding, the other end is pressed in upward soldering and sealing of expansion joint (9) with press strip (16) cover of stainless steel material, with asbestos packing (12) and temperature resistant rubber seal ring (10) contact friction be the stainless steel sealing drum, thereby not perishable in silt.
Claims (2)
1, a kind of directly buried bellows type expansion joint; protecting jacket, dust ring and stainless steel sealing drum are installed on expansion joint; it is characterized in that: bellows outside protecting jacket (3) one ends and bellows welded flange (2) sealing welding; a other end welding baffle ring (8); adorn two glands (11) (14) on the baffle ring; a gland dress asbestos packing (12), another gland dress temperature resistant rubber seal ring (10).
2, require described directly buried bellows type expansion joint according to right 1, it is characterized in that: be through on the expansion joint (9) with a stainless steel sealing drum (15) cover, the airtight soldering and sealing of sealing drum both sides and expansion joint, two seals part temperature resistant rubber seal ring (10) and asbestos packing (12) and the contact friction of stainless steel sealing drum block underground sewage and silt and enter bellows (4) outside.
