Fire extinguishing agent filling device

Abstract

The invention relates to a fire extinguishing technology and discloses a fire extinguishing agent filling device. The fire extinguishing agent filling device is characterized by comprising a valve core, a valve body provided with a stepped through hole, a connecting rod provided with a central runner, a connecting cap and a connector, wherein the stepped through holes are respectively formed in the connecting cap and the connector; a small taper which is sealed and matched with a small hole of the stepped hole of the valve body is arranged at the front end of the valve core; a large cylinder body which is in threaded connection with a large hole of the stepped hole of the valve body is arranged at the rear end of the valve core; a longitudinal blind hole is formed in the center of the large cylinder body; a transverse hole communicated with the bottom of the longitudinal blind hole is formed in the connected part of the small taper and the large cylinder body; the connecting rod penetrates through the connecting cap; the valve body is in threaded connection with the large hole of the stepped through hole of the connecting cap; one end of the connecting rod is arranged in the longitudinal blind hole of the large cylinder body; the other end of the connecting rod is in threaded connection with the large hole of the stepped through hole of the connector. According to the fire extinguishing agent filling device disclosed by the invention, a filling system in which the connecting rod is matched with the hole of the valve core is designed, and thus the simplicity and convenience in operation are realized; after filling, a filling valve is separated from a tool for filling a fire extinguishing agent, and thus the condition that the fire extinguishing agent leaks due to mistaken operation of personnel is avoided.

Description
