The working principle of the pneumatic valve signal gate

signal brake pneumatic valve is set on the basis of the special manual brake pneumatic valve electrical device, pneumatic valve in addition to the design and manufacture according to the national standard, and according to the pneumatic valve installed in the automatic sprinkler system and use characteristics of stainless steel fine grinding of pneumatic valve stem and special packing seal, easy to maintain and add a unique pneumatic valve stem seal o-rings ( Pour sealing) Structure, which can ensure the long-term in a normally open state, the pneumatic valve pneumatic valve stem leakage, not conducive to install and use in condole top. Working principle of the pneumatic valve:
signal gate electrical device is fully enclosed precision mechanical and electrical box structure, using imported stainless parts and electrical components inside the box, under the wheel unit in operation is not easy to be collision pneumatic valve body of the gland. With micro switch and its driving mechanism, on the pneumatic valve stem in a gear and fixed gear meshing transmission, when rotating the handwheel pneumatic valve open/close brake at the same time, the output signal device and the corresponding brake pneumatic valve open/close position of the 'pass', 'broken' electrical signals.
