Standby fastening structure arranged on gate groove of high-pressure gate valve type gate
The invention discloses a standby fastening structure arranged on a high-pressure gate valve type gate groove, a sealing cover plate is arranged at the top of the gate groove, a gate groove connecting flange is arranged on the gate groove, and the gate groove connecting flange and the sealing cover plate are fixed through a plurality of connecting bolts; the standby fastening structure comprises a plurality of connecting assemblies, and each connecting assembly comprises a U-shaped block and a puller bolt. The U-shaped block comprises a U-shaped block upper limb, a U-shaped block vertical limb body and a U-shaped block lower limb, an internal thread through hole is formed in the U-shaped block upper limb, and the puller bolt is connected with the internal thread through hole in a threaded fit mode and abuts against the sealing cover plate; a boss is arranged on the upper surface of the U-shaped block lower limb and extends towards the lower surface of the U-shaped block upper limb, the edge of the door groove connecting flange and the edge of the sealing cover plate are arranged between the boss and the U-shaped block upper limb, and the upper surface of the boss is parallel to and abuts against the lower surface of the door groove connecting flange. When the connecting bolt fails, the standby fastening structure can replace the connecting function of the failed bolt, and early warning of accidents is achieved.
本发明公开了一种设置在高压闸阀式闸门门槽上的备用紧固结构，闸门门槽顶部设有密封盖板，闸门门槽上设有门槽连接法兰，门槽连接法兰与密封盖板之间通过多个连接螺栓进行固定；备用紧固结构包括多个连接组件，连接组件包括U型块和顶紧螺栓；U型块包括U型块上肢、U型块竖直肢身和U型块下肢，U型块上肢上设有内螺纹通孔，顶紧螺栓与该内螺纹通孔通过螺纹配合连接，并与密封盖板相抵接；U型块下肢上表面上设有凸台，凸台向U型块上肢下表面的方向延伸，门槽连接法兰和密封盖板的边缘设置在凸台和U型块上肢之间，凸台上表面与门槽连接法兰下表面平行且相抵接。当连接螺栓失效时，该备用紧固结构能替代失效螺栓的连接功能，预警事故发生。
