Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

In the following description, a lot of specific details have been set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways that are different from those described here, and those skilled in the art can do so without violating the connotation of the utility model. Under the circumstances, similar promotion is done, so the utility model is not limited by the specific embodiments disclosed below.

Secondly, the utility model is described in detail in conjunction with the schematic diagram. When describing the embodiment of the utility model in detail, for the convenience of explanation, the section view showing the structure of the device will not be partially enlarged according to the general scale, and the schematic diagram is only an example, which is here The protection scope of the utility model should not be limited. In addition, the three-dimensional space dimensions of length, width and height should be included in actual production.

As shown in Figures 1 to 3, the utility model includes an opening and closing valve body 1, the upper part of the valve body 1 communicates with an exhaust device 2, and the exhaust device includes an exhaust chamber 21, a buoy 22 and a sealer , the exhaust cavity 21 communicates with the inside of the valve body 1, the top of the exhaust cavity 21 is provided with an exhaust port, the sealer seals the exhaust port, and the buoy 22 is arranged on the exhaust port. The inside of the cavity 21 is connected with the sealer. The opening and closing valve is a gate valve.

The top of the buoy 22 is connected to one end of the connecting rod, and the other end of the connecting rod is connected to the lower part of the sealer, and the sealer includes a seal support 23, a return device 24 and a seal seat with a central through hole 25.
