Abstract
The utility model relates to a pipeline sealing structure, which comprises two butt pipe connectors and thimbles sleeved on the pipe connectors. The pipe connectors are provided with grooves, the grooves are provided with arc-shaped water expansion rubber rings inside. The upper surface and the lower surface of the arc-shaped water expansion rubber ring are arc-shaped and protrude in the same direction. The utility model is provided with the arc-shaped water expansion rubber ring, which, on one hand, makes use of the arc structure of the rubber ring to reduce the width and the height of the groove while ensuring the sealing performance so as to reduce the material waste for arranging groove for the pipe connector and on the other hand, makes use of the water expansion of the rubber ring, realizing that the sealing performance of the pipeline can also be ensured in use, even though the height and the width of the groove is very small. The utility model can be used as sealing structure for an embedded pipe or a top pipe and has a wide applicable prospect.

The rubber seal of circular cross-section or elliptic cross-section is generally adopted in the sealing of existing pipeline, in order to improve sealing effect, need rubber seal to have certain sectional area, therefore, the pipe joint or the collar just need be offered bigger groove for can effective ccontaining rubber seal.Bigger and dark groove has reduced the net sectional area of the pipe joint or the collar on the one hand on the pipe joint or the collar, in order to guarantee its mechanical property, must increase the length and the thickness of the pipe joint or the collar, therefore can cause the waste of material, increased the complexity of installation process on the other hand, need auxiliary implement, install loaded down with trivial details.
The model utility content
The purpose of this utility model provides a kind of seal for pipe joints structure, effectively solves defectives such as needing auxiliary implement when existing seal for pipe joints structure causes waste of material and installation.
To achieve these goals, the utility model provides a kind of seal for pipe joints structure, comprise being two pipe joints that dock shape and being set in the collar on the described pipe joint, offer groove on the described pipe joint, be provided with arc hydro-expansive rubber circle in the described groove.
The upper surface of described arc hydro-expansive rubber circle and lower surface are protruding in the same way arc shape.
The width of described arc hydro-expansive rubber circle is less than the width 2mm～3mm of described groove.
The height of described arc hydro-expansive rubber circle is greater than the height 3mm～5mm of described groove.
To achieve these goals, the utility model also provides a kind of seal for pipe joints structure, comprise being two pipe joints that dock shape and being set in the collar on the described pipe joint, offer groove on the described collar, be provided with arc hydro-expansive rubber circle in the described groove.
The upper surface of described arc hydro-expansive rubber circle and lower surface are protruding in the same way arc shape.
The width of described arc hydro-expansive rubber circle is greater than the width 2mm～3mm of described groove.
The height of described arc hydro-expansive rubber circle is greater than the height 3mm～5mm of described groove.
The utility model proposes a kind of seal for pipe joints structure of new structure, on the pipe joint or the collar, offer groove, arc hydro-expansive rubber circle is set in the groove, utilize the characteristics of rubber ring arcuate structure on the one hand, at the width and the height that guarantee that the sealability prerequisite descends and hangs down groove, and then reduce pipe joint because of offering the waste of material that groove causes, utilize the characteristics of rubber ring water-swellable on the other hand, even realized the width of groove and highly very little, also can in use guarantee the sealability of pipeline, simultaneously, do not need the compression ratio stipulated during installation, just can install without auxiliary implement.The utility model can be used for the sealing configuration of pipe laying or push pipe, is with a wide range of applications.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
