Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figures 1-3: a suspension type anti-seismic structure for a valve comprises a valve sleeve 1, a supporting plate 2 and a frame plate 3; the support plate 3 is connected to a building through a stand column 32, a clamping groove 33 is formed in the upper surface of the support plate 3 along the length direction of the support plate, through openings are formed in two ends of the clamping groove 33 in the length direction, the supporting plate 2 is erected on the bottom surface of the clamping groove 33 along the length direction of the clamping groove 33, hanging ends 23 at two ends of the supporting plate 2 are arranged in a suspended mode through the through openings of the clamping groove 33, the hanging ends 23 are connected to two ends of the valve sleeve 1 in the horizontal direction through cables 11, and the valve sleeve 1 is sleeved on the periphery of the valve body; the valve body hangs through valve barrel 1 and establishes, and frame plate 3 lug connection is in the building, and when the building produced vibrations, vibrations transmission to frame plate 3 back, frame plate 3 took place the displacement with fagging 2 and makes vibrations offset, owing to hang valve barrel 1 and valve body through hawser 11 during fagging 2 displacement to avoid the valve body to produce the displacement, make its influence that receives vibrations fall to minimumly.

Two ends of the valve sleeve 1 in the horizontal direction are respectively provided with a suspension plate 12, and the horizontal height of the suspension plate 12 is higher than the horizontal height of the axis of the valve sleeve 1; the upper surface of the suspension plate 12 is provided with a first hanging ring 121, the hanging end 23 is provided with a second hanging ring 21, and two ends of the cable 11 are respectively connected with the first hanging ring 121 and the second hanging ring 21; the gravity center of the valve body is lowered by improving the horizontal height of the suspension plate 12, the stability of the valve body is improved, and when one end of the mooring rope 11 vibrates through the first hanging ring 121 and the second hanging ring 21, most of vibration energy is absorbed by friction generated by the rings, so that the other end of the mooring rope 11 is kept in a stable state.

The lower surface of the hanging end 23 is provided with a limiting plate 22, and the limiting plate 22 corresponds to two ends of the frame plate 3 in the length direction; when frame plate 3 receives the building influence to produce vibrations, the displacement can take place for frame plate 3 for fagging 2, and limiting plate 22 can carry on spacingly to the displacement scope of fagging 2, avoids fagging 2 displacement too big to lead to the focus skew to lead to valve barrel 1 both ends atress unbalanced.

A spring 221 is arranged on one side of the limiting plate 22 facing the frame plate 3, the spring 221 corresponds to the frame plate 3, and a guard plate 222 is arranged at the connecting position of the spring 221 and the limiting plate 22.
