【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、水や燃料等の液体を圧送する液体圧送装置に関するものである。 The present invention relates to relates to a liquid pumping device for pumping liquids such as water and fuel. 本発明の液体圧送装置は、蒸気使用装置で発生した復水を一旦集め、 Liquid pumping apparatus of the present invention, once collected condensate generated in the steam-using apparatus,
この復水をボイラ―や廃熱利用装置に送る装置として特に適するものである。 Those particularly suitable as a device for feeding in and the waste heat utilization device - this condensate boiler.

【0002】 [0002]

【従来の技術】蒸気使用装置で凝縮して発生した復水は、まだ相当の熱量を有していることが多く、そのためエネルギ―の有効活用のため、液体圧送装置を用いて復水を回収し、この復水をボイラ―や廃熱利用装置に送って廃熱を有効利用する復水回収システムが広く普及している。 Condensate generated by condensation of the Prior Art Steam used device is often still has a quantity of heat equivalent, therefore energy - for effective utilization of the recovered condensate using a liquid pumping device and, the condensate boiler - and waste heat utilization device or send condensate recovery system for effective utilization of waste heat are widely used.

【0003】復水回収システムに利用される液体圧送装置は、復水を一旦密閉容器内に回収し、更に切替え弁を切り換えて密閉容器内に蒸気等の高圧の作動流体を導入し、この作動流体の圧力によって密閉容器内の復水を強制的に排出するものであり、通常比較的低圧の復水を高圧のボイラ―等へ圧送するものである。 [0003] The condensate collected liquid pumping apparatus system is utilized, condensate once collected in a sealed vessel, introducing a high-pressure working fluid such as steam to further the sealed container by switching the switching valve, the operating is intended to forcibly discharge the condensate within the closed vessel by the pressure of the fluid, typically a relatively low pressure condensate high pressure boiler - is intended for pumping the like.

【0004】蒸気使用装置の種類によっては、その一次側圧力と二次側圧力が絶えず変化して、一次側圧力が二次側圧力よりも高くなる場合もある。 [0004] Depending on the type of steam-using apparatus, the primary side pressure and constantly change the secondary pressure, in some cases the primary pressure is higher than the secondary pressure.

【0005】従来の液体圧送装置としては、例えば特開平5−263992号公報に示されたものがある。 [0005] As a conventional liquid pumping device, there is one example disclosed in JP-A-5-263992. これは、蒸気使用装置の一次側圧力が二次側圧力より高くなっても蒸気の漏洩が生じないように、復水溜り室が所定の低水位のときに還元口すなわち圧送液体排出口を閉じ、水位の上昇により圧送液体排出口を開く弁手段をフロ―トに連結したものである。 This is because, as the inlet pressure of the steam-using device leakage steam does not occur even higher than the secondary pressure, condensate reservoir closes the reducing port ie pumping liquid outlet when the predetermined low water level the pumping liquid discharge open mouth valve means flows by the rise in the water level - is the concatenation bets. 弁手段を連結したことにより、一次側圧力が二次側圧力より高くなっても、復水が溜ってフロ―トが上昇しないと弁手段が開弁せず、従って、蒸気の漏洩を防止することができるものである。 By concatenation of the valve means, even if the primary pressure becomes higher than the secondary pressure, condensate is accumulated flow - DOO If does not rise valve means does not open, thus preventing steam leakage it is what it is.

【0006】 [0006]

【発明が解決しようとする課題】上記従来技術の液体圧送装置は、圧力変化による蒸気の漏洩を防止することができるものであるが、一旦密閉容器内に回収した復水を排出するときに素早く排出できないという問題点があった。 THE INVENTION to be solved INVENTION The above prior art liquid pumping device is quickly when it is capable of preventing the leakage of steam due to pressure changes, for discharging the condensate collected once sealed container there is a problem that can not be discharged. これは、復水排出によってフロ―トが降下するときに、フロ―トの降下にほぼ比例して弁手段が閉弁方向に変位し、弁手段の開度が絞られていくためである。 This flow by condensate water discharge - when bets drops, flow - displaced is substantially proportional to the valve means bets descent in the closing direction, in order to gradually narrowed the opening of the valve means.

【0007】フロ―トの降下にほぼ比例して弁手段が閉弁方向に変位すると、弁手段の開度即ち密閉容器内と圧送液体排出口との間の流路が絞られてしまうので、効率良く液体を圧送することができなくなるのである。 [0007] flow - the City of substantially proportional to the valve means to drop is displaced in the closing direction, since the flow path between the opening i.e. closed vessel and pumping liquid outlet valve means will be throttled, efficiently than it becomes impossible for pumping liquid.

【0008】本発明は、従来技術の上記した問題点に注目し、復水排出による密閉容器内の水位の低下に対して、弁手段が全開に近い状態を長く維持できるようにすることである。 [0008] The present invention focuses on the above-mentioned problems of the prior art, with respect to lowering of the water level in the closed container by condensate water discharge is that the valve means to be able to maintain long state close to the full open .

【0009】 [0009]
