Dual-purpose type gas-valve structure

A dual-purpose type gas-valve structure, comprising a box-body, in which multiple horizontal channels and multiple vertical channels are arranged and connected to each other;

• the box-body comprising a lower portion and an upper portion that are integrally formed as a one-piece block of material,
• wherein the multiple horizontal channels comprise a horizontal gas inlet channel and the multiple vertical channels comprises a vertical gas inlet channel intersecting and connected with the horizontal gas inlet channel, wherein the horizontal gas inlet channel and the vertical gas inlet channel are formed in the lower portion of the one-piece block of material of the box-body, and the horizontal gas inlet channel and the vertical gas inlet channel respectively define a horizontal entrance and a vertical entrance, each of which is adapted to selectively receive one of a high-pressure steel cylinder and a plug to insert therein from outside the box body for detachable connection therewith, such that at least one of the horizontal entrance and the vertical entrance is supplied with high-pressure gas from the high-pressure steel cylinder, or is alternatively blocked by the plug;
• wherein the multiple horizontal channels further comprise a lower-layer horizontal channel and an upper-layer horizontal channel that are formed in the upper portion of the one-piece block of the box-body, wherein the lower-layer horizontal channel forms a high-pressure gas control room that is connected to a passage extending from the connection between the horizontal gas inlet channel and the vertical gas inlet channel to receive the high-pressure gas, an aira gas controller being arranged in the high-pressure gas control room to selectively release the high-pressure gas from the high-pressure gas control room, and wherein the multiple vertical channels further comprise a vertical connection channel that connects between the lower-layer horizontal channel and the upper-layer horizontal channel, and the high-pressure gas released from the high-pressure gas control room flows through the vertical connection channel to the upper-layer horizontal channel that serves as a gas outlet channel from which the high-pressure gas is discharged outside;
• and
• wherein the horizontal gas inlet channel and the vertical gas inlet channel are integrated with the high-pressure gas control room and the gas outlet channel by being all formed in the one-piece block of material of the box-body.
