Embodiment
Below in conjunction with attached drawing, the invention will be further described.
As Figure 1-Figure 2, a kind of division end face sealing device, sealing device are full split type structure, including base 1,
Membranous disc 2, O-ring 3 and cover board 4, base 1 are connected on cabin wall 19 by stud 6, and membranous disc 2 is slidably socketed in ship axis 18
On, 18 surface of ship axis is provided with O-ring 3, and O-ring 3 is pressed on 18 surface of ship axis by membranous disc 2, and base 1 is two-half structure,
Connected between two parts of base 1 by bolt 13, straight pin 12, stud 6 has been orderly arranged outside each the first spring washer
7th, the first plain washer 8 and the first nut 9, cover board 4 uses aluminium alloy, nickel aluminum bronze or stainless steel for two-half structure
Material is made, and is connected between two parts of cover board 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 two-half structure using filled-type polytetrafluoroethylene (PTFE), ceramics, high score
Sub- composite material 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 board 4.
Operation principle：The stud 6 of base 1 is fixed on cabin wall 19, O-ring 3 is pressed on ship axis 18 by membranous disc 2
Upper and membranous disc 2 can be rotated synchronously with ship axis 18, and when any cabin water inlet in 19 both sides of cabin wall, the side of membranous disc 2 is in hydraulic pressure
Thrust under be adjacent to 1 another side end face of base, so as to form the sealing friction pair automatism isolation with water-stop
Water is flowed to another cabin.
The utility model has the characteristics that using the above structure：
1st, all parts use two halves split type structure；Compact-sized, small, light weight；
