Abstract
The utility model relates to a connection sleeve which is used to connect a circulating pipe between two or more than two solar energy heat-collectors, in particular to a pipeline flexible connection sleeve which is convenient to be installed and disassembled, belonging to a fittings field of the solar energy heat-collector. The utility model is characterized in that the connection sleeve is a casing pipe which has an inner diameter larger than an outer diameter of the circulating pipe of the solar energy heat-collector, at lease a circle of grooves are opened on two ends of an inner wall of the casing pipe, an elastic sealing ring is embedded into each groove. Namely, a pair of silica sealing rings with U shaped structures are embedded into the grooves of the inner wall on two ends of the connection casing pipe. Two silica sealing rings are clung to the grooves of the casing pipe and the outer wall of the circulating pipe which is to be connected by self-bulging effect, the structure can slide relatively to the circulating pipe, and the bulging force can be increased with the increase of internal pressure of liquid. Not only The connection structure of the utility model is simple, the installation and disassembly is convenient and rapid, and expansion by heating and contraction by cooling can be compensated automatically, but also the sealing force can be self increased with the increase of water pressure in the circulating pipe.
Description
Technical field
The utility model relates to a kind of pipeline flexible adapter sleeve that is used to connect the adapter sleeve, particularly a kind of conveniently assemble and disassemble of circulation pipe between two or the two above solar thermal collectors.Belong to solar thermal collector and use the accessory field.
Background technology
At present, the connection of circulation pipe between the known solar thermal collector, no matter be the connection of circulation pipe between flat plate collector, or the connection of circulation pipe between the vacuum tube collector connecting pipe, mostly adopt flange connection, sebific duct connected mode and the traditional loose joint three kinds of modes that are threaded.Flange connection needs by hand circulation mouth of pipe flange to be formed flange in advance, could clamp rubber cushion with flange plate again could connect, manual flange generally can only be at the good metal of plasticity such as aluminium, copper, and effects such as sealing, outward appearance are subject to operator's technical ability and can not guarantee reliable and stable quality of connection.The sebific duct connected mode is directly to block sebific duct or tie up sebific duct with iron wire with clamp, because solar thermal collector is to place outdoor use, there is high-temperature-hot-water in the circulation pipe for a long time, and the effect of the cold alternation that is heated, very difficult being prone to through the cold alternating action that is heated of sebific duct, clamp and iron wire leaked, and the user is not easy to discover and seize immediately the situation of leaking.The loose joint connected mode needs one section silking of tapping on circulation pipe in advance, twines with flax silk or the raw material band sealing again, installs cumbersomely, connects equally with flange, because be hard connection, be difficult to expanding with heat and contract with cold of bucking-out system and be easy to generate drainage, and installation is inconvenient.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that existing technology exists, and invents a kind of flexible connecting device that can be used for directly connecting circulation pipe between solar thermal collector.
Between the utility model solar thermal collector circulation pipe with flexibly connecting the cover technical scheme that technical problem adopted solution feature be: adapter sleeve is the sleeve pipe (3) of an internal diameter greater than solar thermal collector circulation pipe (1,5) external diameter, sleeve pipe (3) inwall two ends at least respectively have a circle groove (6), are embedded with an elastic seal ring (2) in each groove (6).
Sleeve pipe (3) inwall institute's recessing (6) be shaped as flute profile, swallow-tail form, rectangle or triangular tooth, every circle groove (6) is ring-shaped continuous or discontinuous ring-type.
Elastic seal ring (2) has an elasticity lip (7) in being at least, β angle of angle between two hypotenuses of each elasticity lip (7).
Elastic seal ring (2) global shape that has elasticity lip (7) takes the shape of the letter U, π shape, rectangle, inverted V-shaped or L shaped.
Elastic seal ring (2) adopts silica gel, rubber elastic material.
Each elastic seal ring (2) is inlaid in the shape at the setting-in position in groove (6) inwall and the form fit of groove (6) inwall.
The utility model sleeve pipe (3) can be to adopt hard material to make, also can adopt flexible material to make.
Elastic seal ring (2,4) adopts silica gel, rubber elastomeric material to make.
Elasticity lip (7) on each elastic seal ring (2,4) but one or more, shape can be for various, but have the β angle best, can allow elastic force carry out to predetermined angular like this.
Operation principle: the utility model adapter sleeve is the sleeve pipe (3) of an internal diameter greater than solar thermal collector circulation pipe (1,5) external diameter, at least respectively has a circle groove (6) at sleeve pipe (3) inwall two ends.An elastic seal ring of setting-in (2) in advance in each groove (6), each elastic seal ring (2) are inlaid in the shape and the form fit at the setting-in position in groove (6) inwall.During use, in sleeve pipe (3) inwall two ends grooves (6), place earlier an elastic seal ring (2 separately, 4), elastic seal ring (2) is inlaid in groove (6) inwall, again respectively with the right two sections circulation pipes (1 of a first from left, 5) be pushed in the sleeve pipe (3), because elastic seal ring (2,4) an elasticity lip (7) is arranged, push circulation pipe (1,5) time, elasticity lip (7) hypotenuse at contact circulation pipe () outer wall place all can be extruded and distortion occur, the β angle can allow elasticity lip (7) distortion easier, elasticity lip (7) elastic force that hypotenuse produced makes hypotenuse compress circulation pipe (1,5), elastic seal ring (2,4) inner ring is close to circulation pipe (1,5) outer surface, thereby seal up solar thermal collector circulation pipe (1,5) water channel reaches the purpose that flexibly connects circulation pipe and sealing recirculated water.
The beneficial effects of the utility model are: syndeton is not only simple in structure, the dress folding is convenient and swift, can compensate automatically and expand with heat and contract with cold, and sealing force can also increase voluntarily with the increase of circulation inner pipe water pressure.Can be when connecting the circulation pipe at two ends, sealed circulation system reliably, the negative effect of expanding with heat and contract with cold and producing of self compensating system, and simple in structure, easy for installation.
