従来、定流量の流量を調節するためには、高価な流量調
節可能の定流量弁もしくは高価な可変式定流量ポンプを
使用しなければならなかった。Conventionally, in order to adjust the flow rate of a constant flow rate, an expensive constant flow valve capable of adjusting the flow rate or an expensive variable constant flow pump must be used.
この考案は、圧力容器の圧力変動に関係なく定流量で流
量調節が可能となる、低コストの可変式定流量給液装置
を提供することを目的としたものである。The purpose of this invention is to provide a low-cost variable constant flow rate liquid supply device that can adjust the flow rate at a constant rate regardless of pressure fluctuations in a pressure vessel.
以下、この考案の実施例を図面にもとづいて説明すると
、定流量ポンプ１と圧力容器２との間の給液管３に給液
用流量調節弁４が設けられている。Hereinafter, an embodiment of this invention will be described based on the drawings. A liquid supply flow control valve 4 is provided in a liquid supply pipe 3 between a constant flow pump 1 and a pressure vessel 2.
定流量ポンプ１と給液用流量調節弁４との間の給液管３

パス用流量調節弁６及び気液分離器７が設けられている
。Liquid supply pipe 3 between constant flow pump 1 and liquid supply flow control valve 4
A bypass pipe 5 is branched from the bypass pipe 5, and this bypass pipe 5 is provided with a bypass flow rate control valve 6 and a gas-liquid separator 7.
上記バイパス用流量調節弁６と気液分離器７との間のバ
イパス管５に圧力容器２からの気体加圧管８が接続され
ている。A gas pressurizing pipe 8 from the pressure vessel 2 is connected to the bypass pipe 5 between the bypass flow control valve 6 and the gas-liquid separator 7.
図中９，１０は逆止弁、１１は気体出口管である。In the figure, 9 and 10 are check valves, and 11 is a gas outlet pipe.
給液用流量調節弁４とバイパス用流量調節弁６の入口側
は給液管３にて定流量ポンプに連通しており、前記両調
節弁４，６の出口側は、給液用流量調節弁４が給液管３
にて、バイパス用流量調節弁６がバイパス管５と気体加
圧管８にて、圧力容器２に連通しているので、両調節弁
の出入口の圧力及び圧力差（即ち流量比）は常に等しく
なっている。The inlet sides of the liquid supply flow rate control valve 4 and the bypass flow rate control valve 6 are connected to a constant flow pump via the liquid supply pipe 3, and the outlet sides of both the control valves 4 and 6 are connected to the liquid supply flow rate control valve 6. Valve 4 is liquid supply pipe 3
Since the bypass flow control valve 6 communicates with the pressure vessel 2 through the bypass pipe 5 and the gas pressurization pipe 8, the pressure and pressure difference (i.e., flow rate ratio) at the inlet and outlet of both control valves are always equal. ing.
従って、両調節弁４，６にて、両流量の割合を設定して
おけば、圧力容器の圧力変動にかかわらず、所定の流量
を圧力容器に給液することができる。Therefore, by setting the ratio of both flow rates in both control valves 4 and 6, a predetermined flow rate can be supplied to the pressure vessel regardless of pressure fluctuations in the pressure vessel.
なお、気液分離器７からのバイパス液は排出しても良い
し、また、定流量ポンプサクション側の液体タンク（図
示せず）に回収してもよい。The bypass liquid from the gas-liquid separator 7 may be discharged or may be collected into a liquid tank (not shown) on the suction side of the constant flow pump.
本考案は以上のように構成されているので、圧力容器の
圧力変動に関係なく圧力容器に常に一定量の給液を行う
ことができ、しかも、圧力容器への給液必要量に変更を
生じた場合にも、両調節弁の開度を調節するだけで給液
量を容易に変更させることができる可変式定流量給液装
置とすることができる。Since the present invention is configured as described above, it is possible to always supply a constant amount of liquid to the pressure vessel regardless of pressure fluctuations in the pressure vessel, and moreover, it is possible to always supply a constant amount of liquid to the pressure vessel without changing the amount of liquid required to be supplied to the pressure vessel. Even in such a case, it is possible to provide a variable constant flow liquid supply device in which the amount of liquid supplied can be easily changed by simply adjusting the opening degrees of both control valves.
