Abstract
A rubber seal ring for PVC-M pipe joint belongs to the water supply and drainage pipe technical field and is used for solving the problem of bad sealing caused by deformation of pipe. The technical proposal is that: the rubber seal ring consists of a hard supporting ring and an elastic seal ring which are stacked closely, wherein, the size of the hard supporting ring is 30-50 percent of that of the whole rubber seal ring. The utility model is further provided with the hard supporting ring based on a common rubber seal ring, the hard supporting ring made of polyethylene (PE) or polypropylene (PP) mainly has the function of supporting a pipe port, thereby effectively preventing the rubber ring from being overturned and at the same time reducing resistance during assembly. In addition, the seal ring is provided with seal barbs to improve sealing performance. The utility model which has the advantages of safe and reliable use, easy connection and good sealing performance can be assembled manually or be assembled on the production line during pipe manufacture.
Description
Technical field
The utility model relates to a kind of tubing Sealing, and particularly the O-ring seal that use the joint between the pvc pipe road belongs to plumbing tubing technical field.
Background technique
Continuous development along with science and technology, new material, new process have obtained development and application in succession in each field, continue to bring out at various new material pipelines and modification pipeline aspect the plastics water supply and sewerage pipeline, such as: add the polyvinyl chloride pipeline (PVC-M) that modified additive obtains, this plastic pipe is when having advantages such as former polyvinyl chloride pipeline is in light weight, anticorrosive, intensity is high, easy to connect, toughness enhancing, shock resistance are improved, the wall thickness of pipeline greatly reduces, and reduced pipeline production and user cost, improved the Safety performance of pipeline.But, after reducing wall thickness, toughness strengthens, influenced by environmental temperature, tubing is easy to shrink distortion, and like this, originally the rubber seal cushion rubber of matching used with it one hardness is easy to leak when tubing is out of shape, no longer suitable, be necessary that therefore material and the structure of improving O-ring seal make it adapt to the variation of tubing material.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of can effectively avoiding to be out of shape the O-ring seal that is used for the PVC-M pipeline junction that causes leakage because of tubing.
The alleged problem of the utility model solves with following technical proposals:
A kind of O-ring seal that is used for the PVC-M pipeline junction, its specialization is: it is made up of the rigid support circle 2 and the elastic seal ring 3 of mutual stacked driving fit, and described rigid support circle body is long-pending to be 30%～50% of integral sealing cushion rubber volume.
The above-mentioned O-ring seal that is used for the PVC-M pipeline junction, the inwall place of described elastic seal ring is provided with sealing pawl 3-1, and sealing pawl true dip direction is opposite with rigid support circle side, and described elastic packing ring outer wall place is provided with sealing tooth 3--2.
The above-mentioned O-ring seal that is used for the PVC-M pipeline junction, described elastic seal ring end are provided with Y shape sealing lip limit 3-3.
The utility model improves traditional integrative-structure O-ring seal at the PVC-M pipeline problem that causes leakage that easily deforms, on the basis of rubber seal, set up the rigid support circle, described bracing ring volume is 30%～50% of a whole O-ring seal volume, it adopts polyethylene (PE) or polypropylene (PP) material, hardness is 85 ± 5 ° of Shao Shi, main plaing a part supported pipe end, can prevent effectively that cushion rubber from knocking over, and reduces the installation resistance simultaneously.In addition, the sealing pawl is set on the seal ring, has improved sealing effect.The utility model can be installed by hand, online in the lump installation in the time of also can producing with tubing.Through on probation, receive satisfied effect.The utlity model has advantages such as safe and reliable, easy to connect, good sealing effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model scheme of installation.
The label of each parts is in the accompanying drawing: 1. O-ring seal; 2. rigid support circle; 3. elastic seal ring; 3-1. sealing pawl; 3-2. sealing tooth; 3-3.Y shape sealing lip limit; 4.PVC-M pipeline; 5. bellmouth groove.
Embodiment
Referring to Fig. 1, the utility model and conventional seals circle difference are that it is made up of the rigid support circle 2 and the elastic seal ring 3 of mutual stacked driving fit (can be made of one), and the rigid support circle body is long-pending to be integral sealing cushion rubber 30%～50%.The rigid support circle adopts polyethylene (PE) or polypropylene (PP) material, and hardness is 85 ± 5 ° of Shao Shi, and it mainly plays a part to support pipe end, can prevent effectively that cushion rubber from knocking over, and reduces simultaneously resistance is installed.The elastic seal ring part adopts thermoplastic elastomer (TPE) (TPV), and hardness is 55 ± 5 ° of Shao Shi.The composite co-extruding technology is adopted in the production of O-ring seal, and then by compression molding, perhaps first die casting goes out bracing ring, composite die casted elastic seal ring again, i.e. and secondary die cast can also adopt two injector head notes altogether simultaneously, one-time formed method.
For effectively preventing to leak, be provided with sealing pawl 3-1 at the inwall place of elastic seal ring, sealing pawl true dip direction is opposite with rigid support circle side, and elastic packing ring outer wall place is provided with sealing tooth 3-2.The elastic seal ring end is provided with Y shape sealing lip limit 3-3.
When the utility model is installed, online in the lump installation in the time of also can producing with tubing in the bellmouth groove 5 of direction shown in Figure 2 with its PVC-M pipeline 4 of packing into, can be installed by hand.
Claims (3)
1. O-ring seal that is used for the PVC-M pipeline junction, it is characterized in that: it is made up of the rigid support circle (2) and the elastic seal ring (3) of mutual stacked driving fit, and described rigid support circle body is long-pending to be integral sealing cushion rubber 30%～50%.
2. the O-ring seal that is used for the PVC-M pipeline junction according to claim 1, it is characterized in that: the inwall place of described elastic seal ring is provided with sealing pawl (3-1), sealing pawl true dip direction is opposite with rigid support circle side, and described elastic packing ring outer wall place is provided with sealing tooth (3-2).
3. the O-ring seal that is used for the PVC-M pipeline junction according to claim 1 and 2 is characterized in that: described elastic seal ring end is provided with Y shape sealing lip limit (3-3).
