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 ...

Abstract

The invention discloses a buffering and damping assembly of a vacuum plug-in valve with a guide ring and a buffering and damping method thereof, comprising a valve body, a valve plate located in the valve body, and a guide ring; frame, the guide ring is connected to the bottom of the frame; the bottom of the guide ring is provided with a first buffer mechanism, and the frame and the guide ring are connected through a second buffer mechanism; when the valve plate is closed, the guide ring and When the inner wall of the valve contacts, the first buffer mechanism is used to buffer the impact of the guide ring on the valve body, and the second buffer mechanism is used to temporarily separate the frame from the guide ring. The invention provides a buffer and vibration damping assembly of a vacuum gate valve with a guide ring and a buffer and damping method thereof, so as to solve the problem in the prior art that the closing process of the vacuum gate valve with a guide ring cannot be buffered and damped , to achieve the purpose of meeting the vibration reduction requirements of large vacuum gate valves with guide rings.

Description

technical field [0001] The invention relates to the field of vacuum plug-in valves, in particular to a buffer and vibration-damping component of a vacuum plug-in valve with a guide ring and a buffer and vibration-damping method thereof. Background technique [0002] Before the supersonic flow field is established, the vacuum flapper valve needs to be installed between the vacuum chamber and the external atmospheric environment to cut off the vacuum chamber at the front end of the vacuum flapper valve and the external atmospheric environment; quickly open the vacuum flapper when the supersonic flow field is established The valve connects the front and rear parts of the vacuum valve to form a supersonic airflow channel with good flow field quality. This requires the vacuum gate valve to have the ability to isolate the vacuum environment from the atmospheric environment when it is closed, and to have the ability to communicate with the air flow channel when it is opened.
