Abstract
A seal mechanism of low pressure tube connector relates to a connecting end of a pipe 1 and a connecting end of the pipe 2 which is connected with the pipe 1. The utility model is characterized in that a loop groove 4 is excavated at the connecting end of the pipe 2, and an O-type seal ring 3 is arranged inside the loop groove 4; the upmost outside diameter of the connecting end of the pipe 2 is smaller than the inner diameter of the connecting end of the pipe 1; the outside diameter of the O-type seal ring 3 is larger than the inner diameter of the connecting end of the pipe 1; a bell mouthed opening 5 is arranged at the inner wall of the connecting end of the pipe 1 near the port; therefore, the installation is convenient.
Description
One, technical field
The utility model belongs to pipe coupling, particularly about the sealing configuration of pipe coupling.
Two, background technique
More common seal for pipe joints structure is plane sealing or thread seal, these complex structures, and volume is big, belongs to hard connection, and therefore process complexity when installing/dismounting is had relatively high expectations to plane, screw thread.This model utility is simple in structure, and volume is little, belongs to flexibly connect, and can guarantee sealing effect, assembles easy.
Three, summary of the invention
The purpose of this utility model provides the low pressure pipe joint sealing structure that a kind of new structure is simple, assembling is easy.
Design proposal of the present utility model is:
A kind of low pressure pipe joint sealing structure, relate to the connecting end of a pipeline and the connecting end of another root pipeline that is connected with this pipeline, the connecting end that it is characterized in that a pipeline is provided with circular groove, be with O-ring seals in the circular groove, and: the maximum outside diameter of the connecting end of this pipeline is slightly less than the internal diameter of the connecting end of another root pipeline; The external diameter of O-ring seals is slightly larger than the internal diameter of the connecting end of another root pipeline.
Further scheme is that the connecting end inwall of last pipeline is a horn mouth near the port.
The utility model content is a kind of low pressure pipeline sealing configuration with O-ring seals.Advantage is that sealing effect is good, and design of part is simple.
Four, accompanying drawing and explanation
Fig. 1: embodiment's of the present utility model structural representation
Five, implementation
As Fig. 1, a kind of low pressure pipe joint sealing structure, relate to the connecting end of pipeline 1 and the connecting end of the pipeline 2 that is connected with pipeline 1, the connecting end that it is characterized in that pipeline 2 is provided with circular groove 4, be with O-ring seals 3 in the circular groove 4, and: the maximum outside diameter of the connecting end of pipeline 2 is slightly less than the internal diameter of the connecting end of pipeline 1; The external diameter of O-ring seals 3 is slightly larger than the internal diameter of the connecting end of pipeline 1.
The close port of the connecting end inwall of pipeline 1 is for also being designed to horn mouth 5, so that install.
Further specify as follows: the O RunddichtringO 3 of corresponding specification is inserted in the annular groove of pipeline 2 ends, seal ring 3 can not come off in free state, limit the position of seal ring 3 on pipeline 2 simultaneously, the pipeline 2 that will have seal ring 3 is loaded in the tube chamber of the pipeline 1 of being with horn mouth 5, because seal ring 3 materials are rubber, have resiliently deformable, therefore can adapt to the variation of tube chamber internal pressure, and after selecting corrosion-resistant, aging-resistant rubber material for use, more can guarantee sealing effect.
The connecting end inwall of pipeline 1 also has ring-shaped step among Fig. 1, and pipeline 2 ends are positioned on the step, to reduce fluid resistance.
Claims (2)
1, a kind of low pressure pipe joint sealing structure relates to the connecting end of pipeline (1) and the connecting end of the pipeline (2) that is connected with pipeline (1), it is characterized in that the connecting end of pipeline (2) is provided with circular groove (4), is with O-ring seals (3) in the circular groove (4), and:
