To propose a decompression valve unit capable of easily connecting a decompression valve unit connected to a vertical pipe and piping on a secondary side of the decompression valve unit, even if those are shifted.SOLUTION: A decompression valve unit 1 is equipped with an inflow pipe 10, a water stop valve 11, and a water stop valve connection mechanism 14 connecting the water stop valve 11 to the inflow pipe 10. A decompression valve unit 1C is equipped with a decompression valve 17 connected to the opposite side to the inflow pipe 10 of the water stop valve 11. A first pipe portion 27 is equipped with an upstream side pipe portion 25 extending in a first axial direction X, a downstream side pipe portion 26 extending coaxially with the upstream side pipe portion 25 on a second direction X2 side of the upstream side pipe portion 25, and a rotary connection mechanism 30 that connects the downstream side pipe portion 26 to the upstream side pipe portion 25 so as to be rotatable about a first axis L1. The water stop valve connection mechanism 14 connects the water stop valve 11 to a second pipe part 22 so as to be rotatable about a second axis L2.SELECTED DRAWING: Figure 1
【課題】立て管に接続された減圧弁ユニットと減圧弁ユニットの二次側の配管とがズレていた場合でも、これらの接続を容易に行うことができる減圧弁ユニットを提案すること。【解決手段】減圧弁ユニット１は、流入管１０と、止水栓１１と、止水栓１１を流入管１０に接続する止水栓接続機構１４と、を備える。また、減圧弁ユニット１Ｃは、止水栓１１の流入管１０とは反対側に接続された減圧弁１７と、を備える。第１管部２７は、第１軸方向Ｘに延びる上流側管部２５と、上流側管部２５の第２方向Ｘ２の側で上流側管部２５と同軸に延びる下流側管部２６と、下流側管部２６を上流側管部２５に対して第１軸Ｌ１回りに回転可能に接続する回転接続機構３０と、を備える。止水栓接続機構１４は、第２管部分２２に対して止水栓１１を第２軸Ｌ２回りに回転可能に接続する。【選択図】図１
