Compared with prior art, the beneficial effects of the invention are as follows：
The present invention overcomes the deficiencies in the prior art, can be effectively improved and reduce motion structure gas leakage during the motion
The problem of, and then the yields of product is improved, reduce the cost of product.
Description of the drawings
Fig. 1 is a kind of schematic diagram of the movable sealing structure of high-voltage circuitbreaker.
Specific implementation mode
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
The present invention is a kind of movable sealing structure of high-voltage circuitbreaker, as shown in Figure 1 comprising external shell 1, sealing flange
2,3, two combined seal rings of the first O-ring seal and guide ring 7.External shell 1, sealing flange 2 are that aluminum machine adds part.
External shell 1 is sleeved on sealing flange 2 on transmission shaft 8, and sealing flange 2 is fixed on external shell by bolt 9
On body 1, the first O-ring seal 3 is placed among external shell 1 and sealing flange 2, is made, prevents of ethylene propylene diene rubber
Gas is revealed under static state, and annular groove, the first O-ring seal are equipped with the junction of external shell 1 on sealing flange 2
3 in annular groove.Between 8 three of external shell 1, sealing flange 2 and transmission shaft be equipped with first group of combined seal ring, first
The structure type of group combined seal ring is second O-ring seal 4 made of the package ethylene propylene diene rubber of lip-shaped sealed ring 10
And formed, which is the integrated design, and can not split, and is main sealing element, can play good
Good sealing and cushioning effect.Be additionally provided between external shell 1 and transmission shaft 8 second group positioned at 7 side of guide ring combine it is close
The structure type of seal, two groups of combined seal rings is that side compression is bored in the third O-ring seal 5 made of ethylene propylene diene rubber
Shape sealing ring 6 and formed, most important sealing element.Between external shell 1 and transmission shaft 8, sealing flange 2 and transmission shaft 8 it
Between connected by guide ring 7, make transmission shaft 8 in a circumferential direction to sealing ring (i.e. first group of combined seal ring and second group
Combined seal ring) pressure it is identical, be effectively improved and reduce situations such as motion structure generates eccentric wear during the motion.
The material of guide ring 7 is polytetrafluoroethylene (PTFE) material, and capable of preventing transmission shaft 8, direct friction, protection are outer during exercise with external shell 1
Portion's shell 1 is not damaged with transmission shaft 8.
On sealing flange 2 on external shell 1 be located at 8 three of external shell 1, sealing flange 2 and transmission shaft junction
Equipped with the groove to match with first group of combined seal ring；It is equipped with and second group of group with the junction of transmission shaft 8 on external shell 1
Close the groove that sealing ring matches.
It is connect with transmission shaft 8 on the side that is connect with transmission shaft 8 on first group of combined seal ring, second group of combined seal ring
Side be hard texture rubber, i.e. lip-shaped sealed ring 10 and conical seal ring 6 is the rubber of hard texture.
Due to the hard texture of lip-shaped sealed ring 10, assembly is difficult, therefore is pacified by using the form that sealing flange 2 compresses
Dress；Due to the hard texture of conical seal ring 6, therefore, it is necessary to could be mounted on transmission shaft 8 after being heated.Guide ring 7 be for
Prevent transmission shaft 8 eccentric.
