PROBLEM TO BE SOLVED: To provide a valve gear capable of dispensing with an expensive block joint when a plurality of pipes are assembled to one pipe connection surface of a valve body.SOLUTION: A plurality of refrigerant pipes 17c, 17f are connected to one pipe connection surface 15c of a valve body 15b via a plurality of flange members 21, 22. The flange member 21 has a recessed part 24 formed in a notched shape toward a pipe insertion hole 23 into which the refrigerant pipe 17c is inserted, a protrusion part 25 formed protrusively from the recessed part 24, and a screw insertion hole arranged at the protrusion part 25. The flange member 22 has a pipe insertion hole 27 into which the refrigerant pipe 17f is inserted, a recessed part 28 formed in a notched shape toward the pipe insertion hole 27, a protrusion part 29 formed protrusively from the recessed part 28, and a screw insertion hole arranged at the protrusion part 29. One fixing screw 38 is inserted into both the screw insertion holes which become a continuous state when the recessed part 24 and the protrusion part 29 are combined with each other and the protrusion part 25 and the recessed part 28 are combined with each other, and the flange members 21, 22 are fixed.
【課題】バルブ本体の1つの配管接続面に複数の配管を組み付ける場合において、高価なブロックジョイントを廃止できる弁装置を提供する。【解決手段】バルブ本体15bの1つの配管接続面15cに複数のフランジ部材21,22を介して複数の冷媒配管17c,17fを接続する。フランジ部材21は、冷媒配管17cを挿入する配管挿入孔23に向かって切欠状に形成した凹部24と、凹部24より突出状に形成した凸部25と、凸部25に設けたネジ挿通孔とを備えている。フランジ部材22は、冷媒配管17fを挿入する配管挿入孔27と、配管挿入孔27に向かって切欠状に形成した凹部28と、凹部28より突出状に形成した凸部29と、凸部29に設けたネジ挿通孔とを備えている。凹部24と凸部29とを組み合わせるとともに凸部25と凹部28とを組み合わせると連続状態となる両方のネジ挿通孔に1本の固定ネジ38を挿通し、フランジ部材21,22を固定する。【選択図】図1
