The adapter tube 11 of the embodiment of the application can be customized according to the pipeline of a user, and the installation of process pipelines with different specifications can be realized. When in installation, the user pipeline is butt welded at the two ends of the connecting pipe 11, so that the user pipeline is not required to be perforated, and the site construction is convenient.

As shown in fig. 1, the end of the valve body 5 away from the base 12 is connected to the drive assembly 2, and a feed hole 52 and a mounting hole 51 sealed with the outer wall of the valve stem 3 are provided in the valve body 5. The drive assembly 2 is drivingly connected to the end of the valve stem 3 outside the valve body 5 and is configured to urge the valve stem 3 to slide within the mounting bore 51 to cause the valve stem 3 to block or unblock the feed bore 52. In practice, the movement of the valve stem 3 may be controlled by rotating the drive assembly 2. When the valve rod 3 moves downwards, the valve is opened, and the feeding hole 111 is communicated with the production pipeline, so that the functions of emptying materials of the process pipeline, purging the pipeline, cleaning the pipeline and the like can be realized.

In one implementation of the present embodiment, the drive assembly 2 includes a handwheel 21, a nut 22, a strut 23, and a bearing seat 24. The nut 22 is sleeved on the end of the valve rod 3, which is positioned outside the valve body 5. The hand wheel 21 is sleeved at the end of the nut 22. The plurality of struts 23 are circumferentially disposed at one end of the valve body 5 away from the base 12, and one end of the struts 23 away from the valve body 5 is connected to the bearing seat 24. The bearing seat 24 is sleeved on the nut 22, and a thrust bearing 25 is arranged in a cavity formed between the bearing seat 24 and the nut 22. The movement mode of the titanium material discharging valve is a straight travel. The hand wheel 21 is rotated anticlockwise, the valve is opened, the valve rod 3 moves downwards, and the feeding hole 111 is communicated with a user pipeline, so that the functions of emptying, purging, cleaning and the like of pipeline materials can be realized. Specifically, in the embodiment of the application, by arranging the bearing seat 24 and the thrust bearing 25, the nut 22 is driven to rotate by rotating the hand wheel 21, and the rotation moment of the hand wheel 21 is transmitted to the thrust bearing 25, so that the operation moment is reduced, and an operator can save more labor when rotating the hand wheel 21.

The guide groove 911 is matched with the support rod 23 to ensure that the guide plate 91 can slide on the support rod 23 along with the valve rod 3 when the valve rod 3 moves up and down.

Specifically, since the guide plate 91 is fixed to the valve stem 3, the guide plate 91 moves together with the valve stem 3. Because the support rod 23 is clamped in the guide groove 911, and the support rod 23 is fixed, the support rod 23 can limit the valve rod 3 while guiding the guide plate 91, so that the angular displacement of the valve rod 3 is limited, the valve rod 3 is prevented from rotating, and the valve rod 3 is ensured to move up and down along a straight line. In practice, the guide plate 91 is fixed to the valve stem 3 by means of a pin connection. Specifically, the guide plate 91 and the valve stem 3 are connected by a taper pin. Of course, the guide plate 91 of the embodiment of the present application may be fixed to the valve stem 3 by bolting or the like. In comparison, the pin is easy to install, has reliable self-locking performance and has high positioning accuracy.
