Specifically, the valve rod 2 includes two guide grooves 202 and a plurality of spacing grooves 201, the guide grooves 202 set up at the standing groove both ends and are the symmetric design, the guide groove 202 cross-section is the T type, a plurality of spacing grooves 201 have been seted up to guide groove 202 internal surface equidistance.
During operation, in the using process, the connecting mechanism 5 can be conveniently used, the position of the limiting block 701 can be adjusted along the guide groove 202, and the adjusting block and the limiting block 701 are matched for use to fix the position of the connecting mechanism 5.
Specifically, the lock housing 803 is made of a soft material.
In operation, the locking shell 803 is made of soft material, so that the locking shell 803 is pressed by the expansion sleeve 601 to expand to a certain extent, thereby reducing the gap between the locking mechanism 8 and the connecting mechanism 5.
Specifically, mating threads 801 are cut in the middle of lock housing 803.
During operation, the matching thread 801 is arranged in the middle of the locking shell 803, so that the matching thread 801 is not influenced in the expansion process of the locking shell 803, and the practicability of the device is improved.
The working principle is as follows: in the using process, firstly, the connecting mechanism 5 is connected with the valve rod 2, in the connecting process, the adjusting rod 502 is pressed by the pressing force to move inwards to press the limiting block 701 by pressing the adjusting rod 502, so that the limiting block 701 moves inwards, in the inward moving process of the limiting block 701, the distance between the limiting mechanisms 7 is reduced, the connecting sleeve 506 connected with the limiting block 701 is installed in the placing groove formed in the valve rod 2, the locking shell 803 is installed in the connecting sleeve 506 before the valve rod 2 is installed on the connecting pipe 4, in the placing process, the locking shell 803 presses the pressing block 704 to drive the limiting block 701 to move, so that the limiting block 701 moves out of the limiting groove 201, then the installed valve rod 2 is installed in the connecting pipe 4, before the valve rod 2 is completely inserted into the connecting pipe 4, observing whether the position of the connecting sleeve 506 is the same as the position of the mounting hole position arranged on the disc plate 3 and the position of the mounting hole position arranged on the connecting pipe 4, if the hole positions have deviation, taking out the valve rod 2, primarily adjusting the position of the connecting mechanism 5 to ensure that the position of the hole arranged on the connecting mechanism 5 is close to the positions of the hole arranged on the disc plate 3 and the hole arranged on the connecting pipe 4, inserting the mounting mechanism 6 into the holes arranged on the connecting pipe 4 and the disc plate 3 until the threaded rod 602 in the mounting mechanism 6 enters the locking shell 803, further adjusting the position of the connecting mechanism 5 when the threaded rod 602 enters the locking shell 803 to ensure that the threaded rod 602 can be matched with the matching thread 801, rotating the locking shaft nut, extruding the locking shell 803 under the action of the threaded rod 602 to ensure that the locking shell 803 is completely mounted in the connecting sleeve 506, and arranging a positioning groove 802 matched with the extruding block 704 in the locking shell 803, the locking shell 803 is squeezed to move inwards, when the locking shell 803 moves to a proper position, the squeezing block 704 enters the positioning groove 802, so that the mounting position of the locking shell 803 is limited, and after the squeezing block 704 moves to the positioning groove 802, the limiting block 701 is driven to move downwards under the action of the squeezing block 704, so that the limiting block 701 enters the limiting groove 201, when the limiting block 701 is limited, the position of the connecting mechanism 5 connected with the limiting block 701 is fixed, in the using process, the locking shaft screw block 606 is screwed, because the locking shaft screw block 606 is connected with the threaded rod 602 through the connecting rod 604, the threaded rod 602 can also rotate in the rotating process of the locking shaft screw block 606, because the threaded rod 602 is matched with the matched thread 801, the locking shaft screw block 606 moves inwards, in the inward moving process of the locking shaft screw block 606, the top block 605 arranged at the bottom of the locking shaft screw block 606 can squeeze the adjusting sleeve 603, under the driving of the adjusting sleeve 603, the squeezing force of the expanding sleeve is squeezed, and when the expanding sleeve 606 moves inwards, the sealing gap of the sealing sleeve 601 can be automatically compensated, and the machining precision of a sealing hole can be caused by the requirement and the machining precision of a split type part can be ensured.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
