Problems solved by technology

[0004] However, the pressure difference between the inside and outside of the dynamic sealing structure of the related art is very small. During long-term movement, micro-leakage will occur, which will affect the purity of the ultra-pure gas in the dynamic sealing structure, and then affect the quality of the lamp. If the gas is purified, it needs to consume Lots of energy and raw materials

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the implementation of the present invention is described its structure and working process:

[0018] see Figure 1 to Figure 3 As shown, a dynamic sealing structure is provided with a bottom plate 115, a bushing seat 108 connected with the inner surface of the bottom plate 115, a first O-ring 110 connected with the inner surface of the bottom plate 115 and the bushing seat 108, respectively, The moving shaft 101 inserted through the shaft sleeve seat 108, the first and second oil-free guide sleeves 104, 109 and the first and second Y-shaped sealing rings respectively connected with the shaft sleeve seat 108 and the moving shaft 101 102 and 111 , wherein the first Y-shaped sealing ring 102 is further away from the base plate 115 than the first non-oil-lubricated guide sleeve 104 , and the second Y-shaped sealing ring 111 is closer to the base plate 115 than the second non-oil-lubricated guide sleeve 109 . The dynamic seali...

Abstract

The invention discloses a dynamic seal structure which is provided with a bottom board and also comprises a sleeve pipe seat connected with the inner surface of the bottom board, a first O-shaped seal ring respectively connected with the inner surface of the bottom board and the sleeve pipe seat, a shifting axle penetrating through the sleeve pipe seat and a first oilless lubricating guide sleeve, a second oilless lubricating guide sleeve, a first Y-shaped seal ring and a second Y-shaped seal ring respectively connected with the sleeve pipe seat and the shifting axle. The dynamic seal structure has good sealing.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a dynamic sealing structure. Background technique [0002] The dynamic sealing structure of the related art can be applied to glove boxes in the light manufacturing, lithium battery manufacturing, pharmaceutical and other industries, and includes a plurality of wall panels and a receiving space enclosed by the wall panels, which are accommodated in the receiving space of the dynamic sealing structure. There are ultrapure gases and a number of equipment and instruments. In practical applications, moving parts are installed outside the dynamic sealing structure, such as the cylinder shaft for providing movement, the water jacket shaft for introducing cooling water, etc. [0003] In the dynamic sealing structure of the related art, the moving parts and the wall plate of the dynamic sealing structure must be sealed to ensure the purity of the ultrapure gas in the dynamic sealing structure. ...
