Abstract
The utility model relates to an O-ring seal used at a joint of PVC (polyvinyl chloride) pipelines. The O-ring seal comprises a rubber ring body and is characterized in that a narrow hole is formed in the middle of the rubber ring body, and sealing inverted teeth are formed on the inner wall of the rubber ring body. The O-ring seal provided by the utility model has the characteristics of simple structure, reliability in sealing, convenience in installation and disassembly and material conservation.
Description
Technical field
The utility model relates to the pvc pipe material Sealing in the plumbing tubing technical field, especially a kind of O-ring seal that is used for joint, pvc pipe road.
Background technique
Along with progress of science and technology and The development in society and economy, continue to bring out at various new material pipelines and modification pipeline aspect the plastics water supply and sewerage pipeline.The plastics water supply and sewerage pipeline is in light weight because of having, corrosion-resistant, the intensity advantages of higher, obtains application more and more widely.At present, the sealing of joint, pvc pipe road is adopted cushion rubber extrusion-deformation, makes cushion rubber and the tight applying of pvc pipe material inside and outside wall and plays seal action.The decrement of this kind sealing configuration and cushion rubber has great relation, and decrement is big more, and sealability is good more.Yet decrement is big more, and installing/dismounting is effort more.Therefore, the exploitation sealability is better, easy installation and removal, and the O-ring seal of saving material seems very necessary.
The model utility content
The utility model technical problem to be solved provides a kind of O-ring seal that is used for joint, pvc pipe road that seals reliable, easy installation and removal, saving material.
For addressing the above problem, the described a kind of O-ring seal that is used for joint, pvc pipe road of the utility model comprises the cushion rubber body, and it is characterized in that: the centre of said cushion rubber body is provided with cylindrical void, and its inwall is provided with the sealing pawl.
Said cylindrical void is positioned at the centre of said cushion rubber body, and is uniformly distributed along the circumference.
Said sealing pawl is provided with two-layer, and its true dip direction is towards big end.
The utility model compared with prior art has the following advantages:
1, because the utility model is provided with cylindrical void in the middle of the cushion rubber body, therefore, when the pvc pipe road connects; The cushion rubber inboard is expanded outwardly, and the extruding cylindrical void has reduced the installation resistance; Need not very big thrust can put piping erection in place, thereby reaches the purpose of easy installation and removal.
2, because the utility model is provided with cylindrical void in the middle of cushion rubber, when the pipeline water flowing, cylindrical void inside also is full of water; Along with manifold pressure increases, hydraulic pressure also increases in the cylindrical void, and rubber seal is expanded; Fit tightly with tube wall, therefore, pipeline pressure is big more; It is tight more to fit, and sealability is good more, thereby reaches the reliable sealing purpose.
3, because the utility model is provided with pawl in the cushion rubber inboard, therefore, can effectively stop leakage.
4, because the utility model is provided with cylindrical void in the cushion rubber inboard, therefore, compare, save material about 15%～20% with solid cushion rubber.
5, the utility model is simple in structure, easy uses.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the plan view of the utility model.
Fig. 2 is the plan view of the utility model.
Among the figure: 1-cylindrical void 2-seals pawl.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of O-ring seal that is used for joint, pvc pipe road comprises the cushion rubber body, and the centre of cushion rubber body is provided with cylindrical void 1, and its inwall is provided with sealing pawl 2.
Wherein: cylindrical void 1 is positioned at the centre of cushion rubber body, and is uniformly distributed along the circumference.Sealing pawl 2 is provided with two-layer, and its true dip direction is towards big end.
Claims (3)
1. an O-ring seal that is used for joint, pvc pipe road comprises the cushion rubber body, it is characterized in that: the centre of said cushion rubber body is provided with cylindrical void (1), and its inwall is provided with sealing pawl (2).
