<p>The present invention relates to a gas pressure reducing valve. The gas pressure reducing valve reduces a pressure of a gas supplied from a gas container to a gas consumption device. A pressure reducing space unit connected to a gas container mounting unit and a gas consumption mounting unit is formed in a valve body of the gas pressure reducing valve. A pressure reducing unit is disposed in the pressure reducing space unit. A pressure reducing adjustment hole is disposed on one side of the valve body, and connected to an upper portion of the pressure reducing unit disposed in the pressure reducing space unit. The pressure reducing unit has a guide recess formed inside a cylindrical pressure reducing body thereof. A lower bushing into which an O-ring is inserted is mounted on a lower portion of an inside of the guide recess. A spring inserted into a lower portion of an upper bushing is mounted on the lower bushing. A bushing nut through which the upper bushing penetrates is screw-mounted on an upper portion of the inside of the guide recess. An open/close pin protrudes from a lower portion of the pressure reducing body. A gas inflow hole connected to the inside of the guide recess is formed on the outside of the open/close pin. Accordingly, when a gas device including a portable gas burner is used during the winter, the present invention prevents a reduction or a change in pressure to prevent a reduction in pressure reducing efficiency.</p> |
