It should be understood that the first and second screw holes 10a, 10a may be structural features of the valve body 10 and the self-sealing bonnet 20, respectively, or may be improvements of the present application to achieve removal.
Referring to fig. 1, fig. 1 shows a valve self-sealing bonnet 20 removal device comprising a mounting plate 1, a plurality of guide rods 2, a plurality of connecting rods 3 and a plurality of telescopic mechanisms 4. The guide rods 2 are respectively in threaded connection with the first screw holes 10a, and the guide rods 2 are also respectively arranged on the mounting plate 1 in a penetrating manner and are in sliding fit with the mounting plate 1. The plurality of connecting rods 3 are used for being connected with the plurality of second screw holes in a threaded mode respectively, and the plurality of connecting rods 3 are also used for being connected with the mounting plate 1 respectively. The plurality of telescopic mechanisms 4 are arranged between the mounting plate 1 and the valve body 10 at intervals, and the plurality of telescopic mechanisms 4 can synchronously extend and retract so as to enable the mounting plate 1 to move in a direction away from the valve body 10. Specifically, the mounting plate 1 is connected with the self-sealing valve cover 20 through the connecting rod 3, and can drive the self-sealing valve cover 20 to be separated from the valve body 10 under the action of the telescopic mechanism 4. And in the process, the guide rod 2 can guide the mounting plate 1, so that the problems of dead locking and damage caused by pulling and deviation of the self-sealing valve cover 20 are avoided.
In some examples, the mounting plate 1 has a plurality of first through holes 1a penetrating through its thickness, the plurality of first through holes 1a corresponding to the plurality of first screw holes 10a, the plurality of first through holes 1a for penetrating the plurality of guide bars 2. In this case, the guide bar 2 can be slidably engaged with the mounting plate 1, thereby realizing the guiding action of the guide bar 2 on the mounting plate 1.
In some examples, the mounting plate 1 has a plurality of second through holes through its thickness, the plurality of second through holes corresponding to the plurality of second screw holes, the plurality of second through holes for threading the plurality of connecting rods 3.
