A valve is locking card for valve rod, its characterized in that: the bolt is positioned in the screw seat and is internally formed with an expanding section, the screw seat is internally provided with a through hole for rotatably mounting the bolt, the through hole is also formed into a matched expanding part corresponding to the position of the bolt expanding section, and the expanding section of the bolt is positioned in the expanding part of the through hole, so that the bolt is limited to rotate only in the screw seat.

In the invention, the metal strip ring is sleeved outside the valve body, the fixed mounting sleeve on the inner side wall of the metal strip is sleeved at the upper end of the valve rod after the rotary handle is removed, so that the upper end of the valve rod is hidden in the mounting sleeve, the strip body of the metal strip where the locking sleeve is positioned is fixed at one side of the valve body, the strip body of the metal strip with the tooth openings penetrates into the locking sleeve, and the threads of the bolt in the locking sleeve are meshed with the tooth openings of the strip body, so that the strip body of the tooth openings is fixed in the locking sleeve. Therefore, the valve rod of the valve can be hidden and locked, and other non-professional personnel can be prevented from operating the valve.

When the valve rod needs to be operated, the connection between the opening at the upper end of the locking sleeve and the plug is broken to pull out the plug, then the screw head is rotated through the screwdriver, the bolt is rotated towards one direction, the rack where the tooth opening is located can be pushed out of the locking sleeve downwards through the threads of the bolt, then the mounting sleeve connected with the metal strip is taken down from the upper end of the valve rod, and the valve rod can be operated to rotate.

When the locking rod needs to be locked again, the mounting sleeve is sleeved with the upper end of the valve rod again, the strip body where the tooth opening is located is plugged into the locking sleeve, then the bolt is rotated towards the other direction, the rack where the tooth opening is located is upwards pushed into the locking sleeve by utilizing the threads of the bolt, and then the locking rod can be locked by plugging and fixing the plug again.

Compared with the prior art, the invention can lock the lock rod of the valve when not needed, so that the upper end of the lock rod of the valve is hidden and cannot be operated, and the valve rod can be conveniently exposed again when needed, thereby avoiding non-professional operators from operating the valve rod and having the advantage of convenient use.
