Air supply valve for filling chemical protective clothing with air

Abstract

The present invention relates to an air supply valve for filling chemical protective clothing with air. The present invention comprises: a valve body which includes a first flow path for receiving air of an air tank and a second flow path for receiving air of an air supply unit, has a discharge flow path connected with the first flow path and the second flow path so as to discharge the air of the flow paths, and fills the inside of the chemical protective clothing with the air by supplying, to the inside of the chemical protective clothing, the air discharged from the discharge flow path in the state where the valve body is fixed to the clothing; a socket for supplying the air of the air supply unit to the second flow path of the valve body; and a transfer switch for selectively switching a circulation path of the air by connecting the first flow path or the second flow path of the valve body with the discharging flow path in an alternating state. The present invention can selectively and conveniently switch the circulation path of the air according to the connected location of the air supply member since the first flow path and the second flow path of the valve body are alternately switchd through the transfer switch so as to be connected with the discharge flow path.

Description

technical field [0001] The invention relates to an air supply valve for inflating chemical protective clothing. More specifically, the gas of the gas cylinder is filled inside the chemical protective clothing, or the gas of the gas supplier arranged outside the chemical protective clothing is injected into the chemical protective clothing. Air supply valve inside the chemical protective suit. Background technique [0002] Generally speaking, chemical protective clothing is made of chemical-resistant fabrics and used in biochemical areas or industrial sites contaminated by harmful chemicals. [0003] Such chemical protective clothing 1 is, for example figure 1 As shown, in order to protect the body from harmful chemicals in a sealed state, a structure that covers the entire body is manufactured. [0004] Accordingly, the wearer receives the gas supplied from the gas cylinder after wearing the chemical protective suit 1 with the gas cylinder not shown in the figure. At this...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned general gas supply valve 2 only receives the gas supplied by the gas cylinder, so there is a problem that the active time is restricted, especially the gas of the gas cylinder is used to inflate the inside of the chemical protective clothing 1, so the use of the gas cylinder is significantly shortened. a matter of time
