The invention provides a fault-guided safe gate valve and a vacuum pipeline with the fault-guided safe gate valve. The fault-guided safe gate valve comprises a base, an opening and closing mechanism,a gate and a counterweight assembly, wherein the opening and closing mechanism is arranged on the base; the gate is connected with the opening and closing mechanism, and the opening and closing mechanism is used for driving the gate to move so as to open and close the vacuum pipeline structure; the counterweight assembly is connected with the gate and is used for providing traction force so as toprevent the gate from falling freely due to faults of the opening and closing mechanism, and the traction force provided by the counterweight assembly is larger than the dead weight of the gate. By applying the fault-guided safe gate valve of the technical scheme, the technical problem of low safety performance of the gate valve for a vacuum pipeline in the prior art is solved.
本发明提供了一种故障导向安全的闸板阀及具有其的真空管道,该故障导向安全的闸板阀包括:基座;开闭机构,开闭机构设置在基座上;闸板,闸板与开闭机构连接,开闭机构用于驱动闸板运动以实现真空管道结构的开闭;配重组件,配重组件与闸板连接,配重组件用于提供牵引力以防止开闭机构故障所导致的闸板自由下落,配重组件所提供的牵引力大于闸板的自重。应用本发明的技术方案,以解决现有技术中用于真空管道的闸板阀的安全性能低的技术问题。
