Embodiment 1
[0048] Such as figure 1 and figure 2 The buffer and vibration damping assembly of the vacuum slide valve with guide ring shown includes a valve body 2, a valve plate 17 located in the valve body 2, and a guide ring 12. The valve body 2 also includes a valve connected to the valve plate 17. The frame 1 and the guide ring 12 are connected to the bottom of the frame 1; the bottom of the guide ring 12 is provided with a first buffer mechanism, and the frame 1 and the guide ring 12 are connected through a second buffer mechanism;
[0049] The first buffer mechanism includes a buffer block 11 located at the bottom of the guide ring 12 , and a first elastic member 10 is arranged between the buffer block 11 and the guide ring 12 .
[0050] The second buffer mechanism comprises a frame connecting plate 14, on which the frame connecting plate 14 offers a guide ring connection hole 13, and the long axis of the guide ring connection hole 13 is parallel to the connection line between the...
Embodiment 2
[0060] The buffer and damping assembly of the vacuum gate valve with guide ring, on the basis of embodiment 1, such as Figure 4 , Figure 5 As shown, it also includes a third buffer mechanism and a fourth buffer mechanism;
[0061] The third buffer mechanism: including the flexible buffer 18 arranged on the side of the valve plate 17 facing the inner wall of the valve body 2, when the valve plate 17 is closed, the third buffer mechanism makes the flexible buffer 18 be squeezed between the valve plate 17 and the valve body between 2. The third buffer mechanism also includes a valve plate wheel 16 installed on the valve plate 17, a connecting plate 6 whose two ends are respectively hinged on the frame 1 and the valve plate 17, and also includes a boss 22 arranged on the inner side wall of the valve body 2, and The arc-shaped groove 23 on the inner side wall of the valve body 2 matches the valve plate wheel 16; the valve plate wheel 16 and the arc-shaped groove 23 are all loca...
Embodiment 3
[0072]In this embodiment, the cushioning and vibration reduction method of the vacuum gate valve with guide ring is applied to the vacuum gate valve with guide ring in the supersonic flow channel of a certain equipment. The external dimension of the vacuum gate valve is 3200mm×900mm ×2100mm, made of stainless steel, driven by cylinder.
[0073] A guide ring 12, a frame 1, a valve plate 17, etc. are installed in the valve body 2 of the vacuum plug-in valve. The top of the guide ring 12 is equipped with a guide ring connecting shaft 9. 13 is connected with the frame connecting plate 14; the frame connecting shaft 8 is installed on the lower part of the frame 1, and is connected with the frame connecting plate 14 by inserting into the frame connecting hole 15 on the frame connecting plate 14, and the bottom of the guide ring 12 is connected with a butterfly spring. The end of the spring is connected with a buffer block 11;
[0074] Valve plate wheel 16 is equipped with at frame ...
