Abstract
The utility model discloses a slurry filling sealing ring used for being inserted by a cast iron pipeline. A slurry filling pipe is arranged on a hollow rubber ring. A pressurized line layer is arranged on the inner wall of the rubber ring. The slurry filling sealing ring used for being inserted by a cast iron pipeline has the advantages of wide adaptive range, good seal, and good shock resistant performance. The utility model is convenient for a pipeline to be maintained, and is convenient for labor intensity to be lowered.
Description
The utility model relates to a kind of connection seal ring that is used for the socket joint cast-iron pipe.
Generally be installed in the cast-iron pipe of underground water supply and sewage, because of the time of using long, tube wall or tube head junction point easily produce the crack, cause water leakage phenomenon.The method of now normal employing maintenance has lead joint mouth, asbestos cement interface, expanding cement interface and rubber ring interface.The characteristics though these four kinds of methods are had nothing in common with each other also have deficiency.The subject matter that exists in above-mentioned first three methods is that difficulty of construction is big, and expensive high, benefit is low, poor seismic behavior, and also have unsafe factor is splashed as plumbous liquid and to be hurted sb.'s feelings and hand hammer hitter etc., adopt the rubber ring interface method, limit because of being subjected to the pipe fitting model, Applicable scope is little.
The purpose of this utility model is a kind of wide sealing for tubing joints circle of scope that uses of design.
For realizing above-mentioned task, solution of the present utility model is: seal ring is a hollow rubber circle.On the rubber ring circle body, be fixedly installed on an end of slurry injection pipe on the rubber ring inner layer wall and group is one.Pulp-water can be infused in the rubber ring by slurry injection pipe and solidify.
For making rubber ring can bear certain pressure, not fragile, and play the effect of sealing, the inwall of rubber ring is provided with one deck pressure-bearing line layer.
The sealing circle can be made of plastic materials.
The utility model has the advantages that: simple in structure, easy making; Applied widely, safe ready; Sealing, anti-seismic performance is good.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the generalized section that the utility model fills the slurry seal.
As shown in Figure 1, filling the slurry seal ring is a hollow rubber circle (1), and slurry injection pipe (2) one ends are fixedly installed on the inner layer wall of rubber ring (1), and the other end stretches out outside rubber ring (1).Rubber ring (1) inner wall layer wall is provided with netted pressure-bearing line layer (3), this line with stretchability preferably nylon thread make.During use, the slip casting (2) that will fill the slurry seal ring passes from the mouth of pipe (6) on the bellmouth tube wall (4), uses socket pipe fitting (5) supporting to fill the slurry seal ring then.Slip casting machine is injected into slurries in the rubber ring (1), after filling is full, seals the oral area of slurry injection pipe (2) again, because slurries so just can reach the effect of connection pipe fitting and sealing to the extruding of rubber ring.
Claims (3)
1, a kind of slurry seal ring that fills, it is made up of hollow rubber circle and slurry injection pipe, it is characterized in that: an end of slurry injection pipe (2) is fixedly installed on the inner layer wall of rubber ring (1).
2, by the described slurry seal ring that fills of claim 1, it is characterized in that: rubber ring (1) inwall is provided with pressure-bearing line layer (3).
3, by the described slurry seal ring that fills of claim 1, it is characterized in that: the sealing circle can be made of plastic materials.
