Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
Example one
As shown in fig. 1-5, the downhole valve opening and closing device provided by the present embodiment includes a main rod 1, a valve fixing disk 2 is connected to the bottom of the main rod 1, the valve fixing disk includes a disk 21, a square plug 5 is fixedly connected to the top of the disk 21, and a fixing column 22 is fixedly connected to the bottom of the disk 21, and is used for clamping the valve.
The top of mobile jib 1 is connected with dwang 3, for the convenience of staff's grip, is equipped with anti-skidding line 4 on the 3 outer walls of dwang.
The main rod 1 can be a square tube, and the square plug 5 is inserted into an inner cavity at the bottom of the main rod 1 in a matching way; the wall of the main rod 1 is provided with a through hole 9; a groove 6 is formed in the wall of the square plug 5, an inserting rod 8 is arranged in the groove 6 in a sliding mode, the inserting rod 8 is integrally cylindrical, one end of the inserting rod 8 is connected with a spring 7, the other end of the spring 7 is connected with the wall of the groove 6, and the other end of the inserting rod 8 penetrates through a through hole 9 and extends to the outside of the wall of the main rod 1.
The specific working process is as follows:
when the device is used, the inserting rod 8 is pressed, the spring 7 is pressed, and the inserting rod 8 enters the groove; then the square plug 5 is inserted into the main rod 1, and along with the movement of the square plug 5, when the inserted bar 8 moves to the position of the through hole 9, the inserted bar 8 is inserted into the through hole 9 under the elastic force action of the spring 7, so that the square plug 5 is fixed; when the valve fixed disk 2 of phase adaptation is changed according to the valve of difference, press down inserted bar 8, make inserted bar 8 remove and enter into 1 inside cavity of mobile jib, then with square plug 5 move down can, break away from in 1 from the mobile jib completely to square plug 5, accomplish the dismantlement, then change the installation with the valve fixed disk 2 of phase adaptation can.
Therefore, the valve fixing disc 2 is clamped in the main rod 1 by the square plug 5 through the square plug 5, the inserting rod 8 and the spring 7; the inserting rod 8 is inserted into a through hole 9 in the wall of the main rod 1 to limit the position of the valve fixing disc 2 and prevent the valve fixing disc from falling off from the bottom of the main rod 1; the device abandons threaded connection, is convenient to disassemble and assemble, and adopts a clamping mode, so that the problem that the whole tool is scrapped because the threaded connection is easy to generate a 'thread slipping' phenomenon and cannot be used or disassembled is effectively solved; in addition, because of having the arris on the square plug 5, no matter corotation or reversal, all can effectively carry out the joint cooperation with the mobile jib, drive the valve rotation, can not appear becoming flexible, effectively solve threaded connection between valve fixed disk 2 and the mobile jib 1 and appear becoming flexible and lead to valve fixed disk 2 to twist off from mobile jib 1, can't accomplish the problem of opening and close work.
Example two
With reference to fig. 1 to 5, the other mechanisms of the downhole valve opening and closing device provided in this embodiment are the same as those of the first embodiment, except that the square plug 5 is further provided with a chute 11, the chute 11 is communicated with the groove 6, the chute 11 is slidably connected with a sliding plate 10, the sliding plate 10 is fixedly connected with the inserted link 8, and the sliding plate 10 and the inserted link 8 can be integrally molded and manufactured during machining. By using the sliding plate 10, the friction can be reduced and a certain limiting effect can be provided, so that the phenomenon that the gap between the inserted rod 8 and the groove 6 is too large and large swing occurs in the moving process is prevented, and the inserted rod 8 can move stably.
In addition, when dismantling, in the cavity that makes the inserted bar 8 get into mobile jib 1 for the convenience, that one end that spring 7 was kept away from to inserted bar 8 can be the wedge setting, when using, draws square plug 5 downwards when pressing inserted bar 8, can conveniently make the inserted bar 8 retract in the mobile jib 1 cavity, and then convenient to detach valve fixed disk 2, labour saving and time saving, it is more convenient to operate.
While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
