Description
Technical Field
The utility model relates to a drinking water pipe connection field, concretely relates to inside and outside rubber seal structure for drinking water pipeline connects.
Background
The existing sealing ring structure cannot be adapted to pipelines with various calibers, is not easy to install and take out, and is not good in sealing performance.
Sealing rings with different sizes are often used for pipelines with different calibers, the friction force between the outer part of the existing sealing ring and a sheath is large, and the coating of the flange is easily cut off to cause corrosion points on a joint.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defects of the prior art, an object of the utility model is to provide an inside and outside rubber seal structure for drinking water pipeline connects.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
the utility model provides an inside and outside rubber seal structure for drinking water pipeline connects, includes:
the first sealing ring and the second sealing ring are detachably mounted together, a first sawtooth end face is arranged on the inner side of the first sealing ring, a second sawtooth end face matched with the first sawtooth end face is arranged on the outer side of the second sealing ring, the inner side of the second sealing ring is a plane, the first sealing ring and the second sealing ring are combined in a positive-negative mode through the first sawtooth end face and the second sawtooth end face,
the outer side of the first sealing ring is provided with a corrugated end face for installing an external sheath in a contact mode.
In a preferred embodiment of the present invention, the first and second sealing rings are ring-shaped sealing rings, and the diameter of the first sealing ring is larger than that of the second sealing ring.
In a preferred embodiment of the invention, the sheath is externally mounted with an annular fastening means, which is adjusted by means of a fastening bolt.
The beneficial effects of the utility model reside in that:
the utility model discloses an installation and replacement more be convenient for when the sawtooth zonulae occludens of interior external seal circle and outside sheath are increased to the inside and outside rubber seal circle structure for drinking water pipeline connects.

Detailed Description
The structure and the working principle of the present invention are further explained by the following drawings:
the inner and outer rubber packing structure 100 for a drinking water pipe joint as shown in fig. 1 to 3 includes packings 110 and 120 detachably mounted together, and the diameter of the packing 110 is greater than that of the packing 120. The inner side 111 of the seal ring 110 is provided with a sawtooth end surface 111a, the outer side 121 of the seal ring 120 is provided with a sawtooth end surface 121a matched with the sawtooth end surface 111a, the inner side 122 of the seal ring 120 is a flat sealing surface 122a, the seal rings 110 and 120 are combined in a positive and negative mode through the sawtooth end surface 111a and the sawtooth end surface 121a matched with the sawtooth end surface 111a,
a corrugated end surface 112a is provided at the outer side 112 of the sealing ring 110 for contact mounting of the outer sheath 200. The jacket exterior 200 is mounted with a ring-shaped fastening means 300, the ring-shaped fastening means 300 being adjusted by fastening bolts 310.
The utility model discloses an intensity that is used for inside and outside rubber seal structure 100 of drinking water pipeline joint reaches more than 10.5Mpa, and compression permanent deformation is less than 20%. The best use quality is achieved by reasonably optimizing various indexes influencing the performance of the sealing ring.
The utility model discloses an inside and outside rubber seal structure 100 for drinking water pipeline connects easily installs, every end only need lock a bolt can, to the pipeline of great bore, take out inlayer sealing washer 120 and can be suitable for.
The corrugated connection of the seal ring 110 and the sheath 200 can avoid friction between the seal ring 110 and the sheath 200, thereby enabling the inner and outer rubber seal ring structures 100 to be better assembled in place, preventing the sheath 200 from cutting off the coating of the flange, and avoiding corrosion spots on the joint. The angle deflection of each segment can be allowed to be 4mm during installation, the relative weight is light, and the pipe end can be easily sleeved and installed.
The utility model discloses an inside and outside rubber seal structure 100 for drinking water pipeline connects accords with NSF 61's drinking water standard through international NSF authentication, and the specialty is used for drinking water pipeline to connect sealed.
