气体用减压阀
摘要：
本发明提供一种气体用减压阀，该气体用减压阀在中央部开设有与低压通道和低压室连通的阀孔，并且所述阀机构具有能够落座于阀座上的阀芯，该阀座面对与高压通道连通的阀室，所述阀机构的所述阀芯与压动部件连接并且所述阀机构被收纳在主体内，所述压动部件在所述低压通道以及所述低压室的压力下动作，主体(16)由多个强度不同的主体部件(18、19)接合而构成，高压通道(30、64)全部形成于多个主体部件(18、19)中的高强度的主体部件(18)内，低压通道(85、86、94、119)和低压室(83、84、116)的至少一部分形成于多个主体部件(18、19)中的低强度的主体部件(19)内。由此，能够降低气体用减压阀的成本。
摘要（英）：

A pressure reducing valve for gas has a valve mechanism. The valve mechanism has a valve body having a valve hole opened at its center and communicating with a low-pressure path and a low-pressure chamber and can be seated on a valve seat facing a valve chamber communicating with a high-pressure chamber. The valve mechanism is received in a body with the valve body connected to a pressure receiving member operating according to pressure of the low-pressure path and low-pressure chamber. The body (16) is constructed by joining body members (18, 19) having different strength.The entire portionsof high-pressure paths (30, 64) are formed in the body member (18) having higher strength than the body members (19). Some of the low-pressure paths (85, 86, 94, 119) and low-pressure chambers (83, 84, 116) are formed in the body member (19), which has lower strength. The construction reduces costs of the pressure reducing valve.
