Abstract
The utility model discloses a corrugated expansion joint special for an abrasion-resistant high-temperature furnace slag pipeline. The corrugated expansion joint comprises a corrugated pipe, an inlet end pipe, an outlet end pipe, a protective sleeve fixedly connected to the inner wall of the inlet end pipe and provided with a horn mouth towards an inlet, and thermal insulation materials installed in a cavity between the protective sleeve and the corrugated pipe in a plugged mode, wherein the axial length of the protective sleeve is longer than that of the corrugated pipe. A wearing ring is arranged on the horn mouth of the protective sleeve, the wearing ring is shaped like a turnup horn mouth and is fixedly connected to the inner wall of the horn mouth of the sleeve, and an abrasion-resistant metal layer is arranged on the inner surface of the wearing ring. A check ring is fixedly connected to the outer wall of a port at the other end of the protective sleeve, and the outer wall of the check ring is in clearance fit with an inner hole of the outlet end pipe. According to the corrugated expansion joint, the thermal insulation materials between the protective sleeve and the corrugated pipe cannot lose, and furnace slag cannot enter the cavity between the protective sleeve and the corrugated pipe, so the corrugated pipe is effectively protected; and the wearing ring is arranged in the front of the protective sleeve, so abrasion of the inner wall of the protective sleeve can be obviously reduced, and service life of the corrugated expansion joint is remarkably prolonged.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of corrugated pipe for pipeline compensator.
Background technique
The high temperature furnace slag ash that the blast furnace of steel-making usefulness, the coke oven that coking is used are discharged, usually adopt airtight pipeline to discharge, it is the safe operation of guaranteeing pipeline in the engineering, many arrange in pipeline that corrugated expansion joint absorbs or the axial displacement of compensation pipes, because the high temperature furnace slag ash that the blast furnace of steel-making usefulness, the coke oven that coking is used are discharged is solid granular, and temperature is high, not only very easily gall thinner bellows, and bellows is in easily inefficacy under the high temperature for a long time, prior art has increased sheathed casing in inner chamber, the slag ash that can avoid the flowing bellows that directly weares and teares; Plug dress thermal-protective material in the cavity of sheathed casing and bellows, with the transmission to bellows of the heat that reduces the high temperature furnace slag ash, prolong the working life of bellows, but prior art still exists deficiency: mobile high temperature furnace slag ash is the wearing and tearing sheathed casing directly, sheathed casing is quick-wearing very, and the working life of corrugated expansion joint is still limited; Thermal-protective material between sheathed casing and the bellows can run off the gap between sheathed casing and end pipe, thereby affect effect of heat insulation, slag ash can enter the gap between the pipe from sheathed casing and end in the cavity between sheathed casing and the bellows, affects the compensate function of corrugated expansion joint.
Summary of the invention
The utility model is for the deficiencies in the prior art, proposes a kind of simple and reasonable for structurely, can significantly reduce the sheathed casing wearing and tearing; Can significantly reduce sheathed casing and the gap of end between the pipe, not allow the thermal-protective material between sheathed casing and the bellows run off, also not allow slag ash enter abrasion resistant type high temperature furnace slag ash pipeline special use corrugated expansion joint in the cavity of sheathed casing and bellows.
The utility model is achieved through the following technical solutions technical goal.
The special-purpose corrugated expansion joint of abrasion resistant type high temperature furnace slag ash pipeline, it comprises the horn mouth thermal-protective material that plug fills in the cavity between sheathed casing, sheathed casing and the bellows of import that is fixedly connected with on bellows, entrance point pipe, outlet end pipe, the entrance point inner tube wall, and the axial length of sheathed casing is than ripple pipe range; Its improvements are: the horn mouth place at described sheathed casing arranges wearing ring, and described wearing ring is the flange bell mouth shape, and the bell-mouthed inwall that it is fixedly connected on sleeve pipe is provided with the antifriction metal (AFM) layer at the wearing ring internal surface; Port outer wall at the described sheathed casing the other end is fixedly connected with back-up ring, described back-up ring outer wall and outlet end pipe orifice Spielpassung; Described back-up ring outer wall and outlet end pipe orifice matching gap are 0.6～0.9mm.
The utility model compared with prior art has following good effect:
1. wearing ring is set before sheathed casing, can effectively reduces slag ash to the wearing and tearing of sheathed casing, significantly improve the working life of compensator.
2. the gap between back-up ring and the outlet end pipe is very little; do not allow the thermal-protective material between sheathed casing and the bellows run off; do not allow slag ash enter in the cavity between sheathed casing and the bellows yet; effectively protect bellows, also avoided slag ash to enter the compensate function that cavity between sheathed casing and the bellows affects compensator.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
The special-purpose corrugated expansion joint of abrasion resistant type high temperature furnace slag ash pipeline shown in the drawings, it comprises the horn mouth thermal-protective material 5 that plug fills in the cavity between sheathed casing 4, sheathed casing 4 and the bellows 3 of import that is fixedly connected with on bellows 3, entrance point pipe 1, outlet end pipe 7, entrance point pipe 1 inwall, and the axial length of sheathed casing 4 is longer than bellows 3; Horn mouth place at sheathed casing 4 arranges wearing ring 2, and wearing ring 2 is the flange bell mouth shape, and it is fixedly connected on the bell-mouthed inwall of sleeve pipe 4, is provided with the antifriction metal (AFM) layer at wearing ring 2 internal surfaces; Port outer wall at sheathed casing 4 the other ends is fixedly connected with back-up ring 6, back-up ring 6 outer walls and outlet end pipe 7 endoporus Spielpassung, and in the present embodiment, back-up ring wearing ring 6 outer walls and outlet end pipe 7 endoporus matching gaps are 0.7mm.
The utility model is because the matching gap between back-up ring 6 and the outlet end pipe 7 is very little, do not allow the thermal-protective material 5 between sheathed casing 4 and the bellows 3 run off, do not allow slag ash enter in the cavity between sheathed casing 4 and the bellows 3 yet, effectively protect bellows 3, also avoided slag ash to enter the compensate function that cavity between sheathed casing 4 and the bellows 3 affects compensator; Wearing ring 2 is set before the sheathed casing 4, can significantly reduces the wearing and tearing of sheathed casing 4 inwalls, prolonged more than one times the working life of corrugated expansion joint.
