Abstract
The utility model relates to a sealing ring of pipelines. The T-type and non-skid rubber seal ring comprises the hard glue and flexible glue. The improvement of the utility model is that the metal slide block is arranged inside the hard glue and the external exposure of the metal slide block is servant and forward along the assembling direction of the pipe socket. When the pipes sockets move outward along the axial direction (pull-out) caused by the crustal movement or other constants, the pipes sockets can stop moving outward along the axial direction by the combined action of the converse saw-teeth of the metal slide block and undertaking pipes sockets to avoid sliding.
Description
The utility model relates to a kind of seal ring, especially relates to a kind of seal ring of pipeline.
At present, ductile iron pipe is widely used in the aqueduct in cities and towns, and being tightly connected basically between the pipeline adopted and slipped into formula (T type) flexible interface seal ring.Though this class cushion rubber can adapt to the certain basis distortion, has certain shock resistance, sealability is also better, and its ability that prevents the pipeline slippage is lower.Because interface can not bear axially loaded.Though in practice of construction, be provided with the foundation pier of opposing axial force in the pipe fitting corner and processed locking trough at pipe fitting socket end, by the effect of retaining trip ring and floor clip, possessed certain anti-slip ability, effect is unsatisfactory.
The purpose of this utility model just is to overcome the defective of existing T RunddichtringO, and a kind of new-type antiskid removing rubber seal ring is provided, and makes it be provided with the metal slide block, thereby has high anti-slip ability.
The purpose of this utility model is realized by following technological scheme:
The anti-slip rubber seal of this T type comprises seal ring ebonite 2, seal ring flexible glue 3, and its improvements are to be provided with metal slide block 1 in the described seal ring ebonite 2, and the exposed parts of metal slide block 1 is zigzag fashion, along pipeline socket installation direction for forward.
The both sides that described metal slide block 1 exposes sawtooth have groove 4.
The sawtooth number of teeth that described metal slide block 1 exposes is at least 2 teeth, and the two-end-point of each sawtooth crown is positioned on the seal ring ebonite 2 inner arc faces; The two-end-point that exposes the built-in sawtooth crown of the opposite side of sawtooth with metal slide block 1 is positioned on the seal ring ebonite 2 outer arc faces; The lower end surface of metal slide block 1 and outer side surface are tangent with the lower end surface and the outer side surface of seal ring ebonite 2 respectively.
Described metal slide block 1 has 4 at least, and the width D of each metal slide block 1 is 10-20mm.
Because this anti-slip rubber seal, be to have increased the metal slide block in the inside of original T type rubber seal, therefore when causing that owing to diastrophism or other factors the pipeline socket moves (being pull-off) vertically, the acting in conjunction of the reverse and pipe fitting joint socket by metal slide block sawtooth, make socket can't produce axially outer moving, thereby reach anti-slip effect.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a generalized section of the present utility model.
See also shown in Figure 1ly, T type rubber seal is divided into ebonite 2 and flexible glue 3 two-part among the figure, is evenly distributed with metal slide block 1 in seal ring ebonite 2, and the exposed parts of metal slide block 1 is a zigzag fashion, along pipeline socket installation direction for forward.On the inner arc face of the both sides of metal slide block 1, seal ring ebonite 2, have groove 4.The sawtooth number of teeth that exposes of metal slide block 1 is at least 2 teeth, and the two-end-point of each crown is positioned on the inner arc face of ebonite 2.With the opposite side of sawtooth that exposes of metal slide block 1 sawtooth being arranged also, be to be built in the seal ring ebonite 2, and the two-end-point of this sawtooth crown is positioned on the seal ring ebonite 2 outer arc faces.The lower end surface of metal slide block 1 and outer side surface are tangent with the lower end surface and the outer side surface of ebonite 2 respectively.The last summit of metal slide block 1 is positioned at seal ring flexible glue 3.The width D of each metal slide block 1 is 10-20mm, according to the pipeline nominal diameter, determines the quantity of slug, but is at least 4.
During as installed, anti-slip rubber seal of the present utility model is installed, just can plays sealing and anti-slip effect at the connection part of pipeline.
