Abstract
Description
【発明の詳細な説明】 この発明は気体燃料配管装置に関するものである。[Detailed description of the invention] This invention relates to a gaseous fuel piping system.
従来燃焼装置０１で第１図に示すように気体燃料を燃焼

給側の弁（バーナ弁）０２及び遮蔽弁０３を全閉すると
遮蔽弁０３から弁０２までの間の配管０４に気体燃料が
残留する。In a piping system for burning gaseous fuel in a conventional combustion device 01 as shown in FIG. Gaseous fuel remains in the pipe 04 up to the valve 02.
この場合一般的に残留圧力の方が大気圧よりも高いため
配管０４に取付けられた各種部品や機器から残留気体燃
料が漏洩する。In this case, since the residual pressure is generally higher than the atmospheric pressure, residual gaseous fuel leaks from various parts and equipment attached to the pipe 04.
このリークは残留圧力が高いほど、また残留部容積が大
きいほどリークの可能性も高く、リーク量も大きくなり
、コスト面、安全面ζこ与える影響も大きくなる。The higher the residual pressure and the larger the residual volume, the higher the possibility of leakage, the larger the amount of leakage, and the greater the impact on cost and safety.
この発明は、上記の欠点を解消するため配管内の残留気
体燃料の残圧を必要に応じ減圧させる装置を提供するこ
とを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for reducing the residual pressure of residual gaseous fuel in a pipe as necessary, in order to eliminate the above-mentioned drawbacks.
この発明は気体燃料の残留する配管ζこ圧力スイッチと
その圧力スイッチの信号により作動するベント弁を設け
て配管内の残圧を減圧させる装置に係るものである。This invention relates to an apparatus for reducing the residual pressure in a pipe in which gaseous fuel remains by providing a pressure switch and a vent valve operated by a signal from the pressure switch.

けである。This invention will be explained again with reference to the embodiment shown in FIG. A pressure switch 5 and an exhaust pipe 6 are installed in the pipe line 4 between the shield valve 3 installed on the upstream side of the pipe line 4 for supplying gaseous fuel and the valve 2.2 installed at the inlet of the fuel system. A bed valve 8 is provided in the exhaust pipe 6 via a check valve 7. Valve 2 and pressure switch 5
Signal circuits 10, 11, and 12 are provided between the shield valve 3 and the pressure switch 5, and between the pressure switch 5 and the vent valve 8, respectively.
燃焼装置１を休止し、弁２を全閉し、ついで遮蔽弁３を

管４の残圧を排気五６から逆止弁７を経てベント弁８を
通り開放端９から放出する。When the combustion device 1 is stopped, the valve 2 is fully closed, and the shutoff valve 3 is then fully closed, the pressure switch 5 is activated by the signal from the shutoff valve 3, and the residual pressure in the pipe 4 is set in the pressure switch 5 in advance. When the pressure is higher than a certain level, the pressure switch 5 sends an "open" signal to the vent valve 8, which opens the vent valve 8 and drains the residual pressure in the pipe 4 from the exhaust 56, through the check valve 7, and then to the vent valve 8. It is discharged from the open end 9.
配管４の残圧が圧力スイッチ５にあらかじめ設定された
圧力になれば圧力スイッチ５から「閉」の信号をベン１
−弁８に送りベント弁８を閉じる。When the residual pressure in the pipe 4 reaches the preset pressure in the pressure switch 5, the pressure switch 5 sends a "close" signal to the vent 1.
- Send to valve 8 and close vent valve 8.
圧力スイッチ５に設定する圧力は通常犬猟圧十微用であ
り、また圧力スイッチ５の作動回路は自動と手動の切換
及び緊急作動又は緊急停止の設定を行うことができるも
のとする。The pressure set in the pressure switch 5 is usually sufficient for dog hunting, and the operating circuit of the pressure switch 5 can be switched between automatic and manual modes and can be set for emergency operation or emergency stop.
本発明により配管内の気体燃料残圧を必要に即（７て減
圧さぜることがてきる。According to the present invention, the residual pressure of gaseous fuel in the piping can be immediately reduced as needed.
減圧後の配管内気体燃料残圧を大気圧？こ近いものとす
ることｔこより配管外への気体燃料のリークが防止でき
ると共に配管内への大気のリークも防止できる等の効果
がある。Is the residual pressure of gaseous fuel in the pipe after depressurization atmospheric pressure? By making the pipes close to each other, it is possible to prevent gaseous fuel from leaking out of the piping, and also to prevent atmospheric air from leaking into the piping.
