It is connected with retaining spring 4 with main body 2, ensures that locating rod 5 can keep down and press against kickboard 12, the one end of kickboard 12 is with being arranged on main body
On kickboard axle 13 connect, kickboard torsion spring 14 is installed on kickboard axle 13, forces kickboard 12 to make 90 degree rotations around kickboard axle 13, it is floating
The upper end of board shaft 13 is provided with the screw for fixing kickboard torsion spring, and screw 15 is provided with screw, and the middle part of main body 2, which is provided with, to be used for
Spring 10 is blocked in limitation kickboard position, and the downside of main body 2 is provided with spring mounting groove, compression spring 9 is provided with spring mounting groove, presses
Stone dead wire 11 is provided with contracting spring 9, stone dead wire 11 hauls the return of kickboard 12, and the other end of stone dead wire 11 is connected with kickboard 12,
The upper end of main body 2 is provided with kickboard sealing 6, and sealing ring 7 is provided between shrouding sealing 6 and main body 2, can be in closely to match somebody with somebody with kickboard 12
Close, play sealing function, the lower end outer end of main body 2 is provided with cushion rubber bumper 1, and the cylindrical twice that are provided with of the upper center of main body 2 are floated
Valve sealing 8.
The kickboard 12 installed in main body 2 is in circular plate type, has two ears to coordinate with kickboard axle 13, can be rotated around kickboard axle 13, when
Drilling fluid from the top down by when, kickboard 12 around axially lower rotating opening, downwards after pressure block spring 10, kickboard torsion spring 14 rotates, and floats
Plate 12 is downward, the downward return in the presence of back stop 4 of locating rod 5, no longer works, when drilling fluid stops flowing downward and flowing to
During refluence, kickboard 12 is in the case where blocking the elastic reaction of spring 10 and kickboard torsion spring 13, while also in stone dead wire 11 and the work of compression spring 9
Under, kickboard 12 is rotated up in, is played sealing function until kickboard 12 contacts with kickboard sealing 6, is completed to open and seal
Process, cushion rubber bumper 1 is in annular shape, and consistent with the neck in main body 2, on the body 2, float valve sealing 8 is in T word rings for set installation
Shape, the dress that matches with the upper end groove of main body 2 is formed with the tooling hole on drilling tool on the body 2 to be sealed, and locating rod 5 is in length
