Anti-choke pressure disc valve and pulverized coal pressurizing and feeding unit

Abstract

The utility model discloses a kind of anti-choke disc valve and coal powder pressurization and feeding unit, it is related to coal chemical equipment field, anti-choke disc valve includes disc valve body and pressure transmitter.In coal powder pressurization and feeding unit, first anti-choke valve and second anti-choke valve are connected by first tee pipe, first tee pipe is also connected the first end of first balance pipe, the second end of first balance pipe is connected the inner chamber of coal powder lock hopper, second tee pipe is also connected the first end of second balance pipe, the second end of second balance pipe is connected the inner chamber of coal powder lock hopper, first high pressure regulating valve and second high pressure regulating valve are connected by third tee pipe, third tee pipe is also connected the first end of third balance pipe, the second end of third balance pipe is connected the inner chamber of coal powder lock hopper.Anti-choke disc valve can monitor the internal pressure of the cavity of disc valve body in real time, and timely find choke problem.First balance pipe, second balance pipe and third balance pipe can smoothly discharge the leakage pressure in each valve, ensure that each valve can be normally opened and closed.
