Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides a technical solution: the utility model provides a manual locking lever of preventer, including connecting portion 1, the one end of connecting portion 1 is equipped with the fixed connecting seat 2 of valve looks joint with the preventer in the petroleum well, the other end fixedly connected with of connecting portion 1 is hand wheel 3, extend to the derrick of petroleum well outside the locking operation of preventer through connecting portion 1, make things convenient for the scene to operate more, locate fixed mounting at the center of hand wheel 3 and have count table 4, count table 4 is used for carrying out the technique to the number of turns of turning of hand wheel 3, the preventer carries out the in-process of manual locking through the count of count table 4, the control of the locking angle of assurance to preventer is accurate.
Connecting portion 1 includes first connecting shaft 11 and second connecting shaft 12, the looks remote end of first connecting shaft 11 and second connecting shaft 12 is connected through first universal joint 13, the other end of first connecting shaft 11 is connected with connecting seat 2 through second universal joint 14, the other end and the handle wheel 3 fixed connection of second connecting shaft 12, can make connecting portion 1 be applicable to more service environment through setting up first universal joint 13 and second universal joint 14, can make first universal joint 13 and second universal joint 14 bend according to the distance outside the derrick of preventer, thereby make connecting portion 1 and preventer to the distance phase-match outside the derrick, can carry out better operation to connecting seat 2 through connecting portion 1.
