Detailed Description
The invention is further described with reference to the following figures and examples.
This novel structure of adjusting and fixed butterfly valve butterfly plate position. As shown in fig. 2, the valve comprises a lower valve rod 7, an adjusting screw 13, a pressure plate 9, an end cover 12 and a locking nut 14.
In the structure for adjusting and fixing the position of the butterfly plate of the butterfly valve, as shown in fig. 3, an upper space 71 for installing the adjusting screw 13 and a bottom space 72 for installing the pressure plate 9 are arranged at the end part of the lower valve rod 7; threaded holes 73 are provided for attaching and securing the pressure plate 9.
As shown in FIG. 4, the adjusting screw 13 is provided with a boss 131 which is matched with the upper space 71 at the end part of the lower valve rod 7; threads 132 are provided to mate with the end cap threads 121 and the lock nut threads 141; flat potential 133 is provided to match the adjustment tool.
In the structure for adjusting and fixing the position of the butterfly plate of the butterfly valve, as shown in fig. 5, the pressure plate 9 is provided with a screw hole 92 which is matched with the threaded hole 73 of the lower valve rod; and a mounting hole 91 matched with the excircle of the adjusting screw is arranged.
In the structure for adjusting and fixing the position of the butterfly plate of the butterfly valve, as shown in fig. 2, the adjusting screw 13 is installed in the lower valve rod space 71, and the adjusting screw 13 is fixed at the end of the lower valve rod 7 through the pressure plate 9 and the screw 8.
In the structure for adjusting and fixing the position of the butterfly plate of the butterfly valve, as shown in fig. 6, the end cover 12 is provided with threads 121 which are matched with the threads 132 of the adjusting screw; as shown in fig. 2, is fixed to the end flange of the valve body 10 by screws 11.
As shown in fig. 7, the lock nut 14 is provided with a lock nut thread 141 matching with the adjusting screw thread 132, and a protection space 142 for protecting the adjusting screw; as shown in fig. 2, the lock nut 14 is screwed on the adjusting screw 13 and presses on the end cap 12, and the protection space 142 protects the head of the adjusting screw 13.
According to the structure for adjusting and fixing the position of the butterfly plate of the butterfly valve, the function of adjusting the position of the butterfly plate of the butterfly valve is realized as follows: as shown in fig. 1, the upper valve rod 3 is connected with the butterfly plate 5 through a pin 4, and the lower valve rod 7 is connected with the butterfly plate 5 through a pin 6, so that the upper valve rod 3, the butterfly plate 5 and the lower valve rod 7 form an integral structure; when leakage occurs at the lower opening position 2, a special tool (such as a hand wheel) is sleeved at the position of the flat potential 133 of the adjusting screw exposed out of the end cover 12, the special tool rotates clockwise, and the adjusting screw 13 drags the whole structure to move downwards to realize fine adjustment of the position of the butterfly plate 5; when leakage occurs at the upper opening position 2, the butterfly plate rotates anticlockwise, the adjusting screw 13 pushes the whole structure to move upwards, and the position of the butterfly plate is finely adjusted to meet the sealing requirement.
As described above, in the structure for adjusting and fixing the position of the butterfly plate of the butterfly valve, the function of fixing the position of the butterfly plate 5 of the butterfly valve is realized by: after the position of the butterfly plate 5 is finely adjusted in place, the special tool is taken down, as long as the adjusting screw 13 is not rotated any more, the adjusting screw thread 132 and the thread 121 matched with the end cover play a position locking function, and the position of the butterfly plate 5 cannot move; at the threaded portion of the adjusting screw, where the end cap 12 is exposed, the lock nut 14 is tightened and pressed against the end cap 12, thereby further fixing the position of the butterfly plate 5, and the protective space 142 protects the head of the adjusting screw 13.
