Pressure reducing valve for gas
摘要：
A pressure reducing valve for gas in which a valve mechanism (20) is housed within a body (16, 16') formed by joining two, that is, first and second body members (18,19,19',19'), wherein
a groove (110,133,134) is provided in at least one of joining faces of the body members (18,19;18',19'), the groove (110,133,134) forming a housing chamber (132) for housing heating means (131) or a heating medium passage (109) through which a heating medium flows, the first body member (18, 18') has an insertion hole (25) coaxially housing the valve mechanism (20), a circular cross-section fitting projection (18a) projectingly provided integrally with the first body member (18,18') so as to be coaxial with the insertion hole (25) is her metically fitted into a fitting hole (80) of the second body member (19,19'), and
that the heating medium passage (109) or the housing chamber (132) is disposed at substantially the same position as the valve seat (58) in a direction along an axis of the valve body (59).
摘要（中）：

一种用于气体的减压阀，其中阀机构（20）容纳在通过接合两个即第一和第二主体构件（18,19,19'，19'）形成的主体（16,16'）内， 其特征在于，在所述本体构件（18,19; 18'，19'）的至少一个接合面中设置有槽（110,133,134），所述槽（110,133,134）形成用于容纳加热装置（131）的容纳室（132） 或加热介质流过的加热介质通道（109），第一本体构件（18,18'）具有同轴地容纳阀机构（20）的插入孔（25），圆形的横截面嵌合突起（18a） 与第一本体构件（18,18'）一体地设置成与插入孔（25）同轴的方法是将其与第二本体构件（19,19'）的嵌合孔（80）配合， 并且加热介质通道（109）或容纳室（132）在与阀体（59）的轴线方向大致相同的位置处设置 ）。
