A diaphragm metering pump diaphragm rupture alarm device
By designing an air-inlet and air-outlet/air-outlet component in the diaphragm metering pump, a diaphragm rupture alarm device is introduced, which solves the problem of existing devices being unable to vent or discharge liquid. This enables timely alarm and media discharge in case of diaphragm rupture, ensuring the safety and reliability of the pump.

Abstract
This utility model discloses a diaphragm rupture alarm device for a diaphragm metering pump, relating to the field of diaphragm rupture alarm technology. The device includes a pressure gauge connected to the first end of a tee via a first double-threaded nut. The second end of the tee is connected to a venting and draining assembly. The third end of the tee is connected to a valve guide sleeve via a second double-threaded nut. The valve guide sleeve has a valve ball guide hole that communicates with the interior of the tee. The valve guide sleeve is connected to an air / liquid inlet assembly, which is connected to the diaphragm metering pump. This invention solves the problem that existing pressure gauge-type alarm devices are inconvenient for implementing venting and draining functions.
