Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-Figure 2, a kind of division end face sealing device, sealing device be full split type structure, including base 1,
Membranous disc 2, O-ring 3 and cover plate 4, base 1 are connected on cabin wall 19 by stud 6, and membranous disc 2 is slidably socketed in ship axle 18
On, the surface of ship axle 18 is provided with O-ring 3, and O-ring 3 is pressed on the surface of ship axle 18 by membranous disc 2, and base 1 is two halves formula structure,
Connected by bolt 13, straight pin 12 between two parts of base 1, stud 6 has been orderly arranged outside each the first spring washer
7th, the first plain washer 8 and the first nut 9, cover plate 4 is that two halves formula structure uses aluminium alloy, nickel aluminum bronze or stainless steel
Material is made, connected between two parts of cover plate 4 by bolt 13 and straight pin 12, and bolt 13 has been orderly arranged outside each second spring pad
The 14, second plain washer 15 and the second nut 16 are enclosed, membranous disc 2 is that two halves formula structure uses filled-type polytetrafluoroethylene (PTFE), ceramics, high score
Sub- composite is made, and is connected between two parts of membranous disc 2 by attachment screw 17, and first is provided between base 1 and cabin wall 19
Gasket seal 5, is provided with the second gasket seal 10 between base 1 and cover plate 4.
Operation principle：Base 1 is fixed on cabin wall 19 with stud 6, O-ring 3 is pressed on ship axle 18 by membranous disc 2
