Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in detail below in with reference to the accompanying drawings and embodiments.

Referring to fig. 1, 2, 3, 4 and 5, the present invention provides high temperature hard seal flange butterfly valve, including a swing rod 1, a lifting rod 2, a swing rod 3, a support ring 4, a latch 5, a valve 6, a connection ring 7 and a fixing device 8, where the middle of the swing rod 1 is rotatably connected to the right side of the lifting rod 2 through a rotation shaft, the top of the swing rod 3 is fixed to the bottom of the swing rod 1, the left side of the support ring 4 is connected to the latch 5 through a screw, the valve 6 is fixed to the lower end of the swing rod 3, the middle of the connection ring 7 is rotatably connected to the swing rod 3, the right side of the connection ring 7 is arc welded to the fixing device 8, the fixing device 8 is composed of a cover body 81, a fixing rod 82, a rotation shaft 83, a connection block 84, a fixing block 85, a slide rail 86, a slide bar 87, a push plate 88 and a bolt 89, the left side of the cover body 81 is arc welded to the push plate 7, the inner side of the fixing rod 82 is rotatably connected to the connection block 84 through the rotation shaft 83, the fixing block 85 is fixed to the left side of the fixing device 82, the slide rail 86 is connected to the.

The number of the fixing rods 82 is two, and the fixing rods are symmetrically arranged, so that the front end pipeline and the rear end pipeline can be well fixed.

Wherein, fixed block 85 thickness is 2cm, and the external pipeline of pressing that can be better is fixed.

The length of the sliding rail 86 is the same as that of the fixing rod 82, and the fixing can be well performed.

Wherein, the slide bar 87 is provided with two and corresponds to the two fixed bars 82 , so that the push plate can be better fixed.

The height of the push plate 88 is the same as the length of the bolt 89, and the push plate can well slide in the cover body.

Wherein, the length of the bolt 89 is two thirds of the length of the cover body 81, and the bolt can well rotate in the cover body.

The cover 81 is made of stainless steel.
