Claims (1)
並列接続し、該副管と主管との下流側合流点に切換弁を
配置してなる流体流量の測定装置に於いて、該切換弁の
流体吐出口の下端に、副管側から主管側への流路の切換
えに際しバルブウエートの上昇により副管側流路が遮断
された後、前記流体吐出口の開口を所定時間だけ遅延さ
せるバルブウエートの上昇方向に向って延長された壁面
を形成すると共に、該バルブウエートの主管側に面する
底面積を副管側に面するその上面の面積よりも広く形成
したことを特徴とする副管付き流量メータの切換弁。In a fluid flow rate measuring device, a sub-pipe connected to a sub-meter and a main pipe connected to a parent meter are connected in parallel, and a switching valve is disposed at the downstream confluence of the sub-pipe and the main pipe. At the lower end of the fluid outlet of the valve, when switching the flow path from the auxiliary pipe side to the main pipe side, the opening of the fluid outlet is delayed for a predetermined period of time after the auxiliary pipe side flow path is blocked due to a rise in the valve weight. A sub-wall comprising a wall extending in the upward direction of the valve weight, and a bottom area of the valve weight facing the main pipe side being larger than an area of the top surface thereof facing the sub-pipe side. Switching valve for flow meter with tube.
