Segmented isolation valve for pneumatic conveying system

The invention relates to a segmented isolation valve mounted on the lower back of the elevated guide rail segment, in which a plug (2) is inserted through a flange (4) into a housing (3) hinged to the elevated guide rail (1) and can be quickly connected and disconnected. And the shell (3) is provided with a rainwater runoff box (5). A segmented isolation valve comprises a plug (2) mounted in a housing (3), which is secured to an elevated rail by means of a flange (4) for quick connection and disconnection. The plug (2) is driven by a linear drive (6), the rod of which exerts a force on the engagement piece (7). And the joint piece (7) is pivoted above the plug (2) and is positioned below the frame (8) hinged with the shell base (3). The closing position locking cam (9) is automatically moved by a spring (10) in order to mechanically lock the assembly. The safety lock pin (11) is driven by a release solenoid (12). 本发明涉及一种安装于所述高架导轨段的下背部的分段隔离阀，其中插塞(2)通过法兰(4)插入与高架导轨(1)铰接的壳体(3)，可快速连接和断开。壳体(3)安装有雨水径流箱(5)。分段隔离阀包括安装在
