Abstract
The utility model provides a flexible waterproof sleeve pipe comprising a water pipeline(1), a first and second sleeve pipe(2) (3), and a flexible rubber seal sleeve(4) compactly arranged between a ring flange on the outer annulus surface of the second sleeve pipe(3) end and the ring flange on the outer annulus surface of the water pipeline(1) end by a pressure plate (7), (6) and a bolt(5). The flexible rubber seal sleeve (4) presents ladder and cylinder form in axial as a whole, having a simple structure, an anti-ground subsidence property and a good seal performance, providing an avoidance of confining the pipe in a tight grasp.
Description
Technical field
The utility model relates to the anti-structure of leaking of passing the wall aqueduct, and is especially relevant with the flexible seals of soft waterproof casing.
Background technique
Usually, soft waterproof casing is used between two ponds or between pond and extraneous the connection.Because the sleeve pipe that in the wall in pond, embeds and pass between the aqueduct of this sleeve pipe certain clearance is arranged, this gap should be able to guarantee heat expansion or the shrinkage that aqueduct occurred in summer or winter, or setting of ground cause along sleeve pipe axially or displacement radially.For realizing above-mentioned displacement and anti-leaking, in soft waterproof casing, use rubber o-ring to seal and realize flexibly connecting.But because of this soft waterproof casing complex structure, the installation specification height, and the axial and radial displacement of aqueduct is little, can not satisfy actual requirement of engineering.For example passing the sleeve pipe that embeds DN300 in the wall with the aqueduct of DN250 is example, the radial direction gap is (309 millimeters-273 millimeters) ÷ 2=18 millimeter between the internal diameter in its bassoon and the external diameter of tubule, and the gap at place, location has only (281 millimeters-273 millimeters) ÷ 2=4 millimeter.During again because of usefulness O RunddichtringO sealing, stagnant water effect was bad when the O RunddichtringO was eccentric, and the offset of its permission is that displacement amount generally only is ± 1.5 millimeters.And when in fact being communicated with between two ponds, because of the pond size, depth difference, the setting of ground amount is also different, thereby the aqueduct radial displacement that causes is very big, considerably beyond ± 1.5 millimeters, can cause pipeline stuck thus, pipe wall a large amount of infiltrations of breaking when serious.In sum, soft waterproof casing of the prior art as can be known is complex structure not only, the installation specification height, and the flexible displacement amount that rubber o-ring provides is little, has been not suitable for actual requirement of engineering.
The model utility content
In order to eliminate the problem that exists in the above-mentioned existing soft waterproof casing technology, the utility model provides a kind of simple in structure, easy for installation, big soft waterproof casing of good, the flexible displacement amount of water-proof performance.
In order to achieve the above object, the utility model provides a kind of soft waterproof casing, it comprises the 1st sleeve pipe, the 2nd sleeve pipe and aqueduct, external peripheral surface at a port of the 1st sleeve pipe external port inner peripheral surface and aqueduct utilizes the flange plate fixing seal, between the bottom of the bottom of the inner peripheral surface of the inner port of the 1st sleeve pipe and aqueduct external peripheral surface, support is set, this support is fixed on this aqueduct, compresses by platen and bolt between the flange plate on the external peripheral surface of the external port of flange plate on the external peripheral surface of the another port of aqueduct and the 2nd sleeve pipe the rubber flexible stuffing box gland is installed.
Wherein being preferably described rubber flexible stuffing box gland is made of interior, domestic and abroad glue-line, hangings lay, and integral body is the ladder tubular vertically, a collar flange respectively is set on its two-port external peripheral surface, the uniform bolt hole that is provided with on the collar flange on the little end of diameter embeds reinforcing ring in the flange on the big end of diameter.
The advantage of soft waterproof casing described in the utility model is that easy for installation, flexible displacement amount is big, adaptation foundation settlement performance is good, can not cause pipeline stuck, and its good seal performance, waterproof is reliable.
Description of drawings
Fig. 1 is the sectional view of soft waterproof casing of the present utility model.
Embodiment
Fig. 1 is the sectional view of the utility model soft waterproof casing, comprising: aqueduct (1), the 1st sleeve pipe (2), the 2nd sleeve pipe (3), fixing seal flange plate (10), support (9) and rubber flexible stuffing box gland (4) and platen (6) (7).Wherein, fixing seal has flange plate (10) to be fixed between the inner peripheral surface of external port of the external peripheral surface of port of aqueduct (1) and the 1st sleeve pipe (2), support (9) is set in the 1st sleeve pipe (2), but be fixed on the external peripheral surface of aqueduct (1), the length of this support (9) is 1/3 or 1/4 of its circumference.Utilize bolt (5) and platen (7) (6) rubber flexible stuffing box gland (4) to be fastened on the flange plate on the external peripheral surface of another port of flange plate on the external peripheral surface of external port of the 2nd sleeve pipe (3) and aqueduct (1).The number that is arranged on the flange plate on the 1st, 2 sleeve pipes is relevant with the thickness of pool wall, but only less 1 flange plate will respectively be set at the two-port place of each sleeve pipe.Rubber flexible stuffing box gland (4) integral body vertically is the ladder tubular, and on the external peripheral surface of its two-port flange is set respectively, can embed reinforcing ring (8) in the big flange of diameter.Described rubber flexible stuffing box gland (4) is made after vulcanizing by interior, domestic and abroad glue-line, hangings lay, reinforcing ring parts-mouldings such as (8).
The advantage of soft waterproof casing of the present utility model is that adaptation settlement of foundation performance easy for installation is good, can not make Become pipeline stuck, and its good seal performance, waterproof is reliable. Use rubber flexible sealing shroud of the present utility model After, can pass with the aqueduct of DN250 the sleeve pipe that embeds the DN350 in the pool wall, at this moment bassoon Internal diameter and the external diameter of tubule between the radial direction gap be (359 millimeters-273 millimeters) ÷ 2=43 millimeter. Its gap that is decided to be the place also is 43 millimeters, and this gap is sealed by the rubber flexible sealing shroud entirely, its radial displacement Amount can reach the gap partly, is ± 22 millimeters.
Claims (2)
