Abstract
The utility model discloses a socket joint formula pipeline mechanical sealed rubber ring for the flexible interface, including bulb, supporter, the hardness of bulb is less than the hardness of supporter, recess on the interior anchor ring of supporter certainly the supporter end is to being close to the one end of bulb is deepened gradually. The utility model discloses socket joint formula pipeline sealed rubber ring for interface, simple to operate, sealed effectual.
Description
Technical field
This utility model is related to a kind of sealing ring, in particulars relate to a kind of mechanical flexibility interface sealing of socket type pipeline
Cushion rubber.
Background technology
Ductile iron pipe is water supply and sewage work common pipe materials, and interface is broadly divided into slide-in type flexible interface according to connected mode
With mechanical flexibility interface, wherein K-type interface is modal mechanical flexibility interface, and size shape and the parameter of K-type interface are disclosed
It is embodied in GB/T 13295-2008 standards.The O-ring seal hardness requirement of K-type interface is low, and O-ring seal is generally all softer, and
And the support body portion of O-ring seal is consistent with bulb part hardness.When K-type bulb bell and spigot fit clearance is less, due to propping up
Support body part is softer, is compressed, heaps in installation process, it is impossible to ensure bulb part is pushed, is pressed into place, so as to cause ball
There is the insufficient situation of compression in head point, when inner pipe water pressure is higher, may cause interface leak seal failure.
Utility model content
The purpose of this utility model is to provide a kind of Spigot-and-socket pipe joint O-ring seal, and which is easy for installation, sealing effect
It is really good.
To achieve these goals, technical solution of the present utility model is：A kind of mechanical flexibility of socket type pipeline
Interface O-ring seal, including bulb, supporter, the hardness of the bulb are mutually inserted less than the hardness of the supporter
Supporter storehouse and bulb storehouse are provided between socket together and bellmouth, T bolt passes through bellmouth and differential and can make differential
Move to bellmouth direction, the pressure tongue on the differential is withstood supporter and presses tongue end face to be contacted with the compression face of the supporter,
The bulb is located in bulb storehouse, and the supporter is located in the supporter storehouse.
The mechanical flexibility interface O-ring seal of this utility model socket type pipeline, wherein, the shore hardness of the bulb
For 50 °～70 °.
The mechanical flexibility interface O-ring seal of this utility model socket type pipeline, wherein, the shore of the supporter is hard
Spend for 75 °～95 °.
The mechanical flexibility interface O-ring seal of this utility model socket type pipeline, wherein, the inner ring surface of the supporter
On groove from the supporter end to gradually deepening near one end of the bulb.
After using such scheme, compared with prior art due to this utility model Spigot-and-socket pipe joint O-ring seal ball
Hardness of the hardness of head less than supporter, when installing O-ring seal, supporter is difficult to be compressed due to hardness height, can guarantee that bulb
It is installed in place, it is to avoid leakage occurs when hydraulic pressure is higher caused by bulb is not in place, and supporter is clear-cut in installation process,
It is easy to recognize the position of O-ring seal, installs more convenient；Bulb hardness is relatively low, it is ensured that bulb can be sufficient filling with bulb storehouse,
Make sealing effectiveness more preferable.

Specific embodiment
As shown in figure 1, the mechanical flexibility interface O-ring seal of this utility model socket type pipeline, including bulb 11,
Support body 12, the hardness of bulb 11 are less than the hardness of supporter 12, and the shore hardness of bulb 11 is 50 °～70 °, Shao of supporter 12
Family name's hardness is 75 °～95 °, and 12 end of groove self-supporter on the inner ring surface 121 of supporter 12 is near one end of bulb 11
Gradually deepen.
As shown in Figure 2 and Figure 3, during installation, socket 21 is inserted in bellmouth 22, T bolt 23 passes through bellmouth 22 and differential
24, by tightening the hex-head nut 25 on T bolt 23 so that differential 24 is moved to 22 direction of bellmouth, on differential 24
Pressure tongue withstands supporter 12, and pressure tongue end face is contacted with the compression face of supporter 12, so that T bolt 23 and turret head spiral shell
Female 25 torsion is converted to installing force, supporter 12 is progressively headed in supporter storehouse 31, due to the shore hardness of supporter 12
For 75 °～95 °, during heading into, compression is difficult, supporter 12 can easily determine installation site, work as support
Body 12 is completely into after in supporter storehouse 31, it can be ensured that bulb 11 is entered in bulb storehouse 32.Due to supporter inner ring surface 121
On 12 end of groove self-supporter to gradually deepening near one end of bulb 11, when cushion rubber is installed, it is easier to by glue
Circle pushes to socket end, thus installation process is simpler, meanwhile, the hardness of bulb 11 installs resistance less than the hardness of supporter 12
Power reduces, and bulb can be more satisfactory filling with bulb storehouse 32.
Embodiment described above is only that preferred implementation of the present utility model is described, not new to this practicality
The scope of type is defined, on the premise of without departing from this utility model design spirit, this area ordinary skill technical staff couple
Various modifications and improvement that the technical solution of the utility model is made, all should fall into what claims of the present utility model determined
In protection domain.
