MT-950B

バイパスリリーフ弁
Bypass Relief Valve


液送ポンプにて10K~50K容器等に充填する時、複数の充填器で充填作業を行なっていますが、充填完了で充填器が1台停止、または全充填器が停止する時があります。そのとき、液送ポンプに負担をかけない様に余分の流体をタンクに戻す役目をするのがバイパスリリーフ弁です。
①手動バイパス弁は全充填器の充填量により、液送ポンプの能力が大きく ②バイパスリリーフ弁(MT-950B)で調整できない場合はタンクに常時戻る様に調整をしてください。液送ポンプの能力と充填量との差が少ない場合は②バイパスリリーフ弁だけで使用できます。
 

Bypass Relief Valve is to be used in the operation of the fluid filling of 10K~50K cylinders from the storage tank with added pressure of liquid delivery pump. When one or more of the filling heads stop to discharge (because of any or all of the cylinders are filled up) and the fluid pressure downstream of the pump becomes higher, which condition does overload the pump mechanism and prone to damage it.

Bypass Relief Valve automatically works to send the over- pressured fluid back to the tank to reduce the pressure down to the designed level to protect the pump mechanism.  

Manual operation Bypass Valve helps MT-950B send the overpressured fluid into the bypass line when the liquid delivery pump has the capacity more than that MT-950B alone can regulate, in case Pump discharge capacity is considerably in excess of the total pressure necessary for the filling apparatus.

In case of the pump capacity is matching the fluid filling capacity, automatic Bypass Relief Valve MT-950B alone can serve it.

■バルブサイズ選定方法

(例)

0.5MPaの差圧で、リリーフバルブを使用する場合、ポンプ吐出量が300/min.であり、使用流体がLPGとするならば表より25Aとなる。

(例)

0.4MPaの差圧で、リリーフバルブを使用する場合、ポンプ吐出量が600/min. であり、使用流体の比重が1とするならば、バイパスバルブ吐出量は
 
Q=600x =445/min. となり、表より40Aとなる。

選定におきましては、使用差圧及びポンプ能力が重要な要となりますので、ご不明の点がありましたら、何なりとご相談ください。

■How to Select Correct Size of MT-950B

Ex.1

In case MT-950B is set to work at Differential Pressure of 0.5MPa when Pump Discharge Capacity is 300/min. and Service Fluid is LPG, Size25A is recommended according to the Diagram on the right.

Ex.2

In case MT-950B is set to work at Differential Pressure of 0.4MPa when Pump Discharge Capacity is 600/min. and Specific Gravity of Service Fluid is 1. Discharge Rate of MT-950B shall be:
            Q=600x =445/min.
      Diagram recommends to use Size 40A.

※Working Differential Pressure and Pump Discharge    Capacity are most important factors in selecting Size    of MT-950B. Your inquiry in this connection shall be    quite welcome to us.
