Description

本発明は、火災感知器による火災検出時に予作動弁を開放して２次側配管に加圧消火用水を供給した後にスプリンクラーヘッドの作動で放水させる消火設備に関する。   The present invention relates to a fire extinguishing equipment that opens a pre-actuating valve when a fire is detected by a fire detector and supplies pressurized fire extinguishing water to a secondary pipe, and then discharges the water by operating a sprinkler head.

従来、スプリンクラーヘッドの破損などによる誤放水を防止する消防設備として予作動式のスプリンクラー設備が知られている。   Conventionally, a pre-actuated sprinkler facility is known as a fire fighting facility that prevents accidental water discharge due to damage to the sprinkler head.

予作動式スプリンクラー設備は、防護区画毎に予作動弁装置を設置しており、予作動弁装置は予作動弁として知られた主弁を備え、通常は主弁を閉駆動して加圧水が供給された１次側とスプリンクラーヘッドを接続した２次側とを切り離している。また、主弁の２次側配管には加圧消火用水を充水するか又は圧縮空気を充填している。   Pre-actuated sprinkler equipment is equipped with a pre-actuating valve device for each protection zone, and the pre-acting valve device is equipped with a main valve known as a pre-actuating valve, which is normally supplied with pressurized water by driving the main valve closed. The primary side thus made is separated from the secondary side to which the sprinkler head is connected. Moreover, the secondary side piping of the main valve is filled with pressurized fire-extinguishing water or filled with compressed air.

予作動弁装置は、予作動弁制御盤で火災感知器による火災発報とスプリンクラーヘッドによる減圧検出の両方を判別した場合、又は火災感知器による火災発報を判別した場合、電動弁を用いた遠隔制御弁の開制御により主弁を開駆動し、スプリンクラーヘッドから消火用水を放水させる。   The pre-actuated valve device uses a motorized valve when both the fire alarm by the fire detector and the pressure reduction detection by the sprinkler head are determined by the pre-actuated valve control panel, or when the fire alarm by the fire sensor is determined. The main valve is opened by the opening control of the remote control valve, and the water for fire extinguishing is discharged from the sprinkler head.

ここで、従来の予作動弁装置に使用する主弁は、ピストンシリンダ機構により弁体を開閉駆動しており、この駆動型式として、減圧開放型と加圧開放型がある。   Here, the main valve used in the conventional pre-actuating valve device drives the valve body to open and close by a piston cylinder mechanism, and there are a decompression release type and a pressure release type as this drive type.

減圧開放型の主弁は、ピストンシリンダ機構のシリンダ室に所定の圧力の加圧水充填することにより弁体を閉位置に駆動して閉鎖しており、一方、シリンダ室の排水による減圧で弁体を開位置に駆動して開放するようにしている。   The decompression open type main valve is closed by driving the valve body to the closed position by filling the cylinder chamber of the piston cylinder mechanism with pressurized water at a predetermined pressure, while the valve body is closed by the decompression by drainage of the cylinder chamber. It is opened by driving to the open position.

また、加圧開放型の主弁は、ピストンシリンダ機構のシリンダ室を排水側に開放した状態で弁体を閉位置に駆動して閉鎖しており、一方、シリンダ室に対する１次側の加圧水の供給により弁体を開位置に駆動して開放するようにしている。   Further, the pressure release type main valve is closed by driving the valve body to the closed position with the cylinder chamber of the piston cylinder mechanism opened to the drain side, while the primary side pressurized water with respect to the cylinder chamber is closed. By supplying, the valve body is driven to the open position to be opened.

ところで、予作動弁装置に設けた作動用電動弁は主弁を開閉駆動する遠隔制御弁として機能する重要な機器であり、作動用電動弁が正常に機能する可否かを定期点検や自動試験等により確認しており、作動用電動弁が故障した際には、速やかに新品と交換する作業を必要とする。   By the way, the motor operated valve provided in the pre-actuated valve device is an important device that functions as a remote control valve that opens and closes the main valve. Periodic inspections, automatic tests, etc. check whether the motor operated valve functions normally. Therefore, when the motor-operated valve for operation breaks down, it is necessary to quickly replace it with a new one.

しかしながら、予作動弁装置に減圧駆動型の主弁を設けていた場合、交換のために故障した作動用電動弁を取り外すと、シリンダ室の加圧水が排水され、主弁が開駆動され、２次側に消火用水を充水してしまう。   However, if the pre-actuating valve device is provided with a pressure reducing drive type main valve, removing the malfunctioning motor operated valve for replacement will drain the pressurized water in the cylinder chamber and drive the main valve to open. Fill the side with water for fire extinguishing.

このため作動用電動弁の交換作業が終了して動作を確認した後に、主弁のシリンダ室に1次側から消火用水を加圧充填して閉駆動して設備運用状態に戻す必要があり、作動用電動弁を交換をした後の復旧に手間と時間がかかる問題がある。   For this reason, after the operation of exchanging the electric motor valve for operation is completed and the operation is confirmed, it is necessary to pressurize and fill the cylinder chamber of the main valve with fire-extinguishing water from the primary side and drive it closed to return to the equipment operation state. There is a problem that it takes time and effort to recover after replacing the electric valve for operation.

また、予作動弁制御盤は多数の防護区画に設置した予作動弁装置の監視制御を行っており、作動用電動弁を交換するために故障した作動用電動弁を取り外すと、予作動弁制御盤で断線が検出されて断線警報が不必要に出力される問題がある。   In addition, the pre-operating valve control panel monitors and controls the pre-operating valve devices installed in a number of protective compartments, and if the malfunctioning electric valve is removed to replace the operating electric valve, the pre-operating valve control panel There is a problem that a disconnection is detected on the panel and a disconnection alarm is output unnecessarily.

また、作動用電動弁の交換作業中に、その防護区画で火災が発生した場合、予作動弁制御盤は、交換作業中の作動用電動弁に開制御信号を送って動作させようとし、例えば取り外している信号線に駆動電圧が印加されることで、短絡事故を起こしたり、作業員が感電するといった不足の事態を招く恐れもある。   In addition, when a fire occurs in the protection zone during the operation of replacing the motor operated valve, the pre-actuated valve control panel attempts to operate by sending an open control signal to the motor operated valve being replaced, for example, When the drive voltage is applied to the signal line that is being removed, there may be a short-circuit accident or a shortage such as an electric shock from an operator.

本発明は、弁部が常時充水されている作動用電動弁を交換する場合に起きる主弁の開駆動や監視制御の異常を未然に防止可能とする消火設備を提供することを目的とする。   It is an object of the present invention to provide a fire extinguishing facility that can prevent an abnormality in driving and monitoring control of a main valve that occurs when a motor-operated valve whose valve portion is constantly filled is replaced. .

In a fire extinguisher equipped with an electric valve, an electric valve is provided between the operating motor valve and the cylinder chamber of the main valve, and the control unit closes the electric valve when an operation stop signal of the operating motor valve is detected. As a result, the motorized valve is closed and closed by remote control of the control unit prior to replacement, so that even if the malfunctioning motorized valve is removed, the pressurized water in the cylinder chamber will not be drained.

Here, since the manual start valve is connected in parallel with the series connection of the motor operated valve and the motor operated valve or in parallel with the motor operated valve, in particular, the series connection of the motor operated valve and the operated motor operated valve When a manual start valve is connected in parallel, the main valve can be driven to open by draining from the cylinder chamber by opening the manual start valve even when the operating motor valve is being replaced. In the event that a fire breaks out in the protection zone during the replacement of the motorized valve, the fire can be extinguished by sprinkling water from the sprinkler head operated by opening the manual start valve on the pre-actuating valve device side.

（火災検出による電動弁の閉制御禁止による効果）
また、制御部は、火災感知器により火災を検出した場合に、電動弁の開制御を禁止するようにしたため、火災による作動用電動弁の開制御により主弁を確実に開駆動してスプリンクラーヘッドから加圧消火用水を散水して消火可能とする。
(Effect of prohibiting closed control of motorized valve due to fire detection)
In addition, when the fire is detected by the fire detector, the control unit prohibits the open control of the motorized valve. Fire water can be extinguished by sprinkling pressurized fire extinguishing water.

Therefore, by closing the motorized valve as an on-site operation prior to replacement, the pressurized water in the cylinder chamber will not be drained even if the malfunctioning motorized valve is removed. Therefore, it is possible to reliably prevent the malfunction of opening the main valve, thereby making it unnecessary to perform recovery work for the malfunction of opening, and to reduce the burden of replacing the actuating electric valve.

（手動起動弁の接続による効果）
ここで、仕切弁と作動用電動弁との直列接続と並列に、又は作動用電動弁と並列に、手動起動弁を接続するようにしたため、特に仕切弁と作動用電動弁との直列接続と並列に手動起動弁を接続している場合には、作動用電動弁の交換中であっても、手動起動弁を開操作することでシリンダ室からの排水により主弁を開駆動可能とし、作動用電動弁の交換中に、その防護区画で、万一、火災が発生した場合に、予作動弁装置側の手動起動弁の開操作で作動したスプリンクラーヘッドかの散水による消火を可能とする。 (Effects of connecting a manual start valve)
Here, since the manual start valve is connected in parallel with the series connection of the gate valve and the motor operated valve or in parallel with the motor operated valve, in particular, the series connection of the gate valve and the motor operated valve When a manual start valve is connected in parallel, the main valve can be driven to open by draining from the cylinder chamber by opening the manual start valve even when the operating motor valve is being replaced. In the event that a fire breaks out in the protective compartment during the replacement of the motorized valve, the sprinkler head that was activated by opening the manual start valve on the pre-actuating valve device can be extinguished by watering.

（作動用電動弁交換中の断線監視解除、開制御禁止、注意警報による効果）
また、作動用電動弁の交換を開始する場合に運用停止位置に操作する運用停止スイッチを設け、制御部は、運用停止スイッチによる運用停止操作の入力を検出した場合に、交換する作動用電動弁の断線監視の禁止、交換する作動用電動弁を設けた防護区画の火災検出又は火災検出と減圧検出を判別した場合の作動用電動弁の開制御の禁止、及び運用停止スイッチが運用停止位置にあることを示す注意警報を行うようにしたため、作動用電動弁の交換作業に先立ち制御部の運用停止スイッチを運用停止位置に操作しておくことで、作動用電動弁を取り外しても断線警報は不必要に出力されず，また、作動用電動弁を交換している防護区画で火災が発生しても交換中の作動用電動弁に開制御信号が不必要に出力されることを確実に防止可能とし、更に、運用停止スイッチが運用停止位置にあることを示す注意警報として、スイッチ注意灯の作動と所定時間毎の音響警報の出力することで、作動用電動弁が交換作業中にあることが分かり、また、交換作業が終了した後の運用停止スイッチの戻し忘れを防止可能とする。 (Effects of disconnection monitoring cancellation, open control prohibition, caution alarm during motor valve replacement for operation)

A terminal test valve 28 is provided on the terminal side of the branch pipe 22, and its secondary side is connected to the drain pipe 32 via the orifice 30.

［予作動弁装置の構成］
図２は交換用電動弁を設けた予作動弁装置の実施形態を示した説明図である。図２に示すように、予作動弁装置２４は予作動弁として機能する減圧開放型の主弁４２を備えている。主弁４２の１次側には手動操作により開閉する制御弁４０を設け、ポンプ設備から分岐配管２２により加圧消火用水の供給を受けている。主弁４２の２次側の分岐配管２２は防護区画に引き出され、そこに閉鎖型のスプリンクラーヘッド２６を接続している。 [Configuration of pre-actuated valve device]
FIG. 2 is an explanatory view showing an embodiment of a pre-acting valve device provided with a replacement electric valve. As shown in FIG. 2, the pre-actuating valve device 24 includes a decompression-release type main valve 42 that functions as a pre-acting valve. A control valve 40 that is manually opened and closed is provided on the primary side of the main valve 42, and is supplied with pressurized fire-extinguishing water through the branch pipe 22 from the pump equipment. The branch pipe 22 on the secondary side of the main valve 42 is drawn out to a protection section, and a closed sprinkler head 26 is connected thereto.

主弁４２は通常状態で閉鎖しており、その２次側の分岐配管２２には充水弁５６を開いて１次側から供給した加圧水を充填している。   The main valve 42 is closed in a normal state, and the secondary branch pipe 22 is filled with pressurized water supplied from the primary side by opening the water filling valve 56.

主弁４２は開閉駆動機構として、シリンダ室４４の中に弁体を兼ねたピストン４６を、リターンスプリング４８を介して摺動自在に配置したピストンシリンダ機構を設けている。設備の使用を開始する場合や火災鎮火に対し設備を復旧する場合、シリンダ室４４に１次側の加圧水を、仕切弁６８、オリフィス７０、逆止弁７２を通る経路で充水し、シリンダ室４４の圧力を所定圧力に保つことでピストン４６をストロークして弁座４５に押し当てて弁閉鎖状態としている。   The main valve 42 is provided with a piston cylinder mechanism in which a piston 46 that also serves as a valve body is slidably disposed via a return spring 48 in a cylinder chamber 44 as an opening / closing drive mechanism. When starting the use of the equipment or when restoring the equipment against fire extinguishing, the pressurized water on the primary side is filled in the cylinder chamber 44 through a route passing through the gate valve 68, the orifice 70, and the check valve 72, and the cylinder chamber is filled. By maintaining the pressure of 44 at a predetermined pressure, the piston 46 is stroked and pressed against the valve seat 45 so that the valve is closed.

主弁４２の開放は作動用電動弁５０により行う。作動用電動弁５０はシリンダ室４４をドレイン（排水）に接続する経路に設けており、通常は閉鎖している。作動用電動弁５０には例えばリミットスイッチを用いた開閉検出器５２を設け、全開又は全閉を検出可能としている。また、作動用電動弁５０と並列に手動起動弁５４を接続し、手動起動弁５４を開操作することで、現場での主弁４２の開閉駆動を可能としている。
The main valve 42 is opened by the motor operated valve 50 for operation. The motor-operated valve 50 is provided in a path connecting the cylinder chamber 44 to a drain (drainage) and is normally closed. An open / close detector 52 using, for example, a limit switch is provided in the operating motor operated valve 50 so that full open or full close can be detected. Further, the manual start valve 54 is connected in parallel with the electric motor for operation 50, and the manual start valve 54 is opened, so that the main valve 42 can be opened and closed on site.

２次側の分岐配管２２に接続しているスプリンクラーヘッド２６が火災による熱気流を受けて開放すると、開放したスプリンクラーヘッド２６からの放水を開始する。このとき主弁４２の２次側に設けている減圧検出器６０によりスプリンクラーヘッド２６の作動による減圧を検出し、減圧検出信号を図１の予作動弁制御盤３６に送って主弁４２の作動を表示させる。   When the sprinkler head 26 connected to the branch pipe 22 on the secondary side receives a thermal air current due to a fire and opens, water discharge from the opened sprinkler head 26 is started. At this time, the decompression detector 60 provided on the secondary side of the main valve 42 detects the decompression due to the operation of the sprinkler head 26 and sends the decompression detection signal to the pre-actuated valve control panel 36 in FIG. Is displayed.

図１に示した予作動弁制御盤３６は、例えば防護区画に設置した火災感知器３５による火災検出と減圧検出器６０による減圧検出を判別した場合、作動用電動弁５０に開制御信号を中継器３４を介して送って開制御する。   The pre-actuated valve control panel 36 shown in FIG. 1 relays an open control signal to the actuating motor-operated valve 50 when, for example, a fire detection by the fire detector 35 installed in the protection section and a decompression detection by the decompression detector 60 are determined. It is sent through the device 34 to control the opening.

作動用電動弁５０を開制御すると、シリンダ室４４の加圧水が開放した作動用電動弁５０を通って排水され、シリンダ室４４の圧力が減圧し、１次側からの押圧をピストン４６が受けてリターンスプリング４８に抗してストロークし、主弁４２を開駆動し、開放したスプリンクラーヘッド２６に加圧消火用水を送って放水させる。   When the actuation motor valve 50 is controlled to open, the pressurized water in the cylinder chamber 44 is drained through the opened actuation valve 50, the pressure in the cylinder chamber 44 is reduced, and the piston 46 receives pressure from the primary side. Stroke is performed against the return spring 48, the main valve 42 is driven to open, and the fire-extinguishing water is sent to the opened sprinkler head 26 for discharge.

またスプリンクラーヘッド２６が開放して放水を開始すると、その１次側の分岐配管２２を介して給水本管１６の圧力が低下し、この減圧を図１の圧力タンク１８に設けている圧力スイッチ２０で検出して、ポンプ制御盤１４が消火ポンプ１０を始動して継続的に加圧水を供給して放水する。
Further, when the sprinkler head 26 is opened and water discharge is started, the pressure of the water supply main pipe 16 is reduced through the branch pipe 22 on the primary side, and the pressure switch 20 provided in the pressure tank 18 of FIG. , The pump control panel 14 starts the fire pump 10 and continuously supplies pressurized water to discharge water.

また、主弁４２の開放による２次側への流水は流水検出器６２で検出する。流水検出器６２に対しては、主弁４２の弁座４５の弁体シート面に開口した開口穴からの配管を接続し、オリフィス６４及び逆止弁６６を介してドレイン側に接続している。   Further, the flowing water to the secondary side due to the opening of the main valve 42 is detected by the flowing water detector 62. To the flowing water detector 62, a pipe from an opening hole opened in the valve body seat surface of the valve seat 45 of the main valve 42 is connected, and connected to the drain side through the orifice 64 and the check valve 66. .

主弁４２がピストン４６のストロークにより開放すると、弁座４５からピストン４６が離れることで、流水検出器６２への配管に１次側の加圧水を供給し、これによって所定時間の遅延タイマ分継続して水圧が加わったときに流水検出器６２が作動し、流水検出信号を図１の予作動弁制御盤３６に出力して放水表示を行う。このとき流水検出器６２に加わる加圧水はオリフィス６４及び逆止弁６６を通って排水側に流れる。   When the main valve 42 is opened by the stroke of the piston 46, the piston 46 is separated from the valve seat 45, whereby the primary pressurized water is supplied to the piping to the flowing water detector 62, and this continues for a predetermined delay timer. When the water pressure is applied, the water flow detector 62 is operated, and a water flow detection signal is output to the pre-actuated valve control panel 36 of FIG. 1 to display the water discharge. At this time, the pressurized water applied to the flowing water detector 62 flows through the orifice 64 and the check valve 66 to the drain side.

（交換用電動弁の設置）
図２に示す予作動弁装置２４にあっては、作動用電動弁５０と主弁４２のシリンダ室４４を結ぶ配管に交換用電動弁７４を設け、中継器３４を介して図１に示した予作動弁制御盤３６からの信号線を接続している。交換用電動弁７４は通常は開放しており、作動用電動弁５０が故障して交換する際に、図１の予作動弁制御盤３６での操作に基づく閉制御信号を受けて閉制御し、故障した作動用電動弁５０を新品と交換するために取り外しても、シリンダ室４４の加圧水が作動用電動弁５０を取り外した配管部分から排出されて閉駆動されることを阻止する。 (Installation of replacement electric valve)
In the pre-actuating valve device 24 shown in FIG. 2, a replacement electric valve 74 is provided in the pipe connecting the electric motor valve 50 for operation and the cylinder chamber 44 of the main valve 42, and the electric valve 74 shown in FIG. The signal line from the pre-actuated valve control panel 36 is connected. The replacement motor-operated valve 74 is normally open. When the motor-operated valve 50 is replaced due to a failure, the replacement motor-operated valve 74 is closed by receiving a close control signal based on the operation of the pre-actuated valve control panel 36 in FIG. Even if the malfunctioning motor-operated valve 50 is removed for replacement with a new one, the pressurized water in the cylinder chamber 44 is prevented from being discharged from the pipe portion from which the motor-operated valve 50 is removed and driven to close.

また、交換用電動弁７４には例えばリミットスイッチを用いた開閉検出器７６を設け、全開又は全閉を検出可能としている。   In addition, the replacement electric valve 74 is provided with an open / close detector 76 using a limit switch, for example, so that full open or full close can be detected.

また、交換用電動弁７４と作動用電動弁５０の直列接続に対し手動起動弁５４を並列接続しており、交換用電動弁７４を閉制御した状態で故障した作動用電動弁５０を取り外した状態であっても、必要に応じて手動起動弁５４を開操作することで、シリンダ室４４の加圧水を排水して主弁４２を開駆動可能としている。   Further, the manual start valve 54 is connected in parallel to the series connection of the replacement motor valve 74 and the actuation motor valve 50, and the malfunctioning motor valve 50 is removed while the replacement motor valve 74 is closed. Even in the state, by opening the manual start valve 54 as necessary, the pressurized water in the cylinder chamber 44 can be drained and the main valve 42 can be driven to open.

（予作動弁制御盤の制御機能）
予作動弁制御盤３６の制御部１００は、例えばダブルインターロック制御として、防護区画Ａ１〜Ａｎ毎に、火災感知器３５による火災検出と減圧検出器６０による減圧検出の両方を判別した場合に、予作動弁装置２４に設けた作動用電動弁５０に開制御信号を出力して遠隔的に開制御し、これに伴い予作動弁として機能する主弁４２を開駆動し、スプリンクラーヘッド２６の開放作動に伴う加圧消火用水の放水を可能とする制御を行う。 (Control function of pre-actuated valve control panel)
When the control unit 100 of the pre-actuated valve control panel 36 determines both fire detection by the fire detector 35 and decompression detection by the decompression detector 60 for each of the protection sections A1 to An, for example, as double interlock control, An open control signal is output to the motor operated valve 50 provided in the pre-actuating valve device 24 to remotely control the opening, and the main valve 42 functioning as a pre-acting valve is driven to open, and the sprinkler head 26 is opened. Control to enable water discharge for pressurized fire extinguishing with operation.

また、制御部１００は、別の制御として、火災感知器３５による火災検出ができない障害検出、例えば伝送障害、断線、短絡、運用停止、商用電源断などの障害検出と減圧検出器６０による減圧検出の両方を判別した場合に、作動用電動弁５０に開制御信号を出力して開制御し、これにより主弁４２を開駆動し、スプリンクラーヘッド２６の開放動作に伴う加圧消火用水の放水を可能とする制御を行う。   In addition, as another control, the control unit 100 detects a failure that cannot be detected by the fire detector 35, for example, a failure detection such as a transmission failure, disconnection, short circuit, operation stop, or commercial power supply disconnection, and a decompression detection by the decompression detector 60.

When the acceptance of the opening operation is detected, a closing control signal is output to the replacement motor operated valve 74 in the protective section A1 to perform the closing control. As a result, as shown in FIG. 2, even when the malfunctioning motor-operated valve 50 is removed, the pressurized water in the cylinder chamber 44 is not discharged, and the main valve 42 is prevented from being opened.

また、制御部１００は、操作部１０２による防護区画Ａ１を指定した交換用電動弁７４の開操作の受付けを検出したときに、火災感知器３５により火災を検出した場合は、交換用電動弁７４の開制御を禁止する制御を行い、火災検出により作動用電動弁５０を開制御することで主弁４２を確実に開駆動してスプリンクラーヘッド２６からの加圧消火用水の放水を可能とする。
In addition, when the control unit 100 detects acceptance of the opening operation of the replacement motor operated valve 74 that designates the protection zone A1 by the operation unit 102, when the fire is detected by the fire sensor 35 , the replacement motor operated valve 74. The opening control of the motor valve 50 is controlled so as to control the opening of the motor-operated valve 50 by detecting a fire, so that the main valve 42 is reliably driven to open and the sprinkler head 26 can discharge the pressurized fire-extinguishing water.

また、制御部１００は、防護区画Ａ１の作動用電動弁５０の交換に伴い、操作部１０２に設けた運用停止スイッチ１１０による運用停止操作の受付けを検出した場合、表示部１０４に指示してスイッチ注意灯を点灯又は点滅させ、また、警報部１０６に指示して運用停止スイッチ１１０が運用停止位置にあることを示す所定の音声警報又は音響警報を一定時間毎に繰り返し出力させる制御を行う。このため、予作動弁制御盤３６側で担当者は運用停止スイッチ１１０を運用停止位置に操作していることを簡単且つ確実に認識可能となり、作動用電動弁５０の交換作業が終了した場合の運用停止スイッチ１１０の戻し忘れを防止可能とする。   Further, when the control unit 100 detects acceptance of the operation stop operation by the operation stop switch 110 provided in the operation unit 102 in accordance with the replacement of the operation motor operated valve 50 in the protection section A1, the control unit 100 instructs the display unit 104 to switch The warning light is turned on or blinked, and control is performed to repeatedly output a predetermined audio alarm or acoustic alarm indicating that the operation stop switch 110 is in the operation stop position at regular intervals by instructing the alarm unit 106. For this reason, the person in charge on the side of the pre-operating valve control panel 36 can easily and reliably recognize that the operation stop switch 110 has been operated to the operation stop position, and the replacement work of the operating electric valve 50 is completed. It is possible to prevent forgetting to return the operation stop switch 110.

また、制御部１００は、操作部１０２に設けた運用停止スイッチ１１０による運用停止操作の入力を検出した場合、防護区画Ａ１に設けた作動用電動弁５０の断線監視を解除するか、断線を検出しても断線警報を出さないようにする制御を行う。このため、故障した作動用電動弁５０の交換作業で予作動弁制御盤３６からの信号線を取り外して断線状態としても、予作動弁制御盤３６から断線警報が出されることはない。   In addition, when the control unit 100 detects an operation stop operation input by the operation stop switch 110 provided in the operation unit 102, the control unit 100 cancels the disconnection monitoring of the actuation motor operated valve 50 provided in the protection section A1 or detects the disconnection. Even so, control is performed so as not to issue a disconnection alarm. For this reason, even if the signal line from the pre-actuating valve control panel 36 is removed and the disconnection state is caused by exchanging the malfunctioning motor-operated valve 50, a disconnection alarm is not issued from the pre-acting valve control panel 36.

また、制御部１００は、操作部１０２に設けた運用停止スイッチ１１０による運用停止操作の受付けを検出した場合、例えば防護区画Ａ１に設けた火災感知器３５による火災検出と減圧検出器６０による減圧検出の両方を判別しても、作動用電動弁５０に対する開制御信号の出力を禁止する制御を行う。このため作動用電動弁５０の交換作業中に、予作動弁制御盤３６からの信号線に開制御信号の信号電圧を加えることがなく、短絡事故や感電事故を確実に防止可能とする。   When the control unit 100 detects acceptance of the operation stop operation by the operation stop switch 110 provided in the operation unit 102, for example, the fire detection by the fire detector 35 provided in the protection section A1 and the pressure reduction detection by the pressure reduction detector 60 are performed. Even if both are discriminated, the control for prohibiting the output of the open control signal to the motor operated valve 50 is performed. For this reason, it is possible to reliably prevent a short-circuit accident or an electric shock accident without applying the signal voltage of the open control signal to the signal line from the pre-actuating valve control panel 36 during the replacement operation of the electric valve 50 for operation.

なお、制御部１００は、運用停止スイッチ１１０による運用停止操作の入力を検出した場合に交換用電動弁７４を閉制御し、運用停止スイッチ１１０による運用停止解除操作の受付けを検出した場合に交換用電動弁７４を開制御するようにしても良い。   The control unit 100 closes the replacement electric valve 74 when detecting an operation stop operation input by the operation stop switch 110, and replaces when the operation stop release operation is accepted by the operation stop switch 110. The motorized valve 74 may be controlled to be opened.

この制御により、運用停止スイッチ１１０の運用停止位置への操作により交換用電動弁７４を閉制御して、交換作業に伴う主弁４２の開放誤動作を確実に防止し、また、運用停止スイッチ１１０の運用停止解除位置への操作により交換用電動弁７４を開制御し、交換作業の終了に伴う交換用電動弁７４の復旧忘れを防止可能とする。
With this control, the replacement electric valve 74 is controlled to be closed by operating the operation stop switch 110 to the operation stop position, thereby reliably preventing the malfunction of opening the main valve 42 due to the replacement work. The replacement motor-operated valve 74 is controlled to be opened by operating the operation stop release position, so that it is possible to prevent forgetting to restore the replacement motor-operated valve 74 when the replacement work is completed.

（作動用電動弁の交換に伴う制御動作）
図４は作動用電動弁の交換に伴う予作動弁制御盤の監視制御を示したフローチャートである。 (Control action associated with replacement of the motor valve for operation)
FIG. 4 is a flowchart showing the monitoring control of the pre-actuated valve control panel accompanying the replacement of the actuating electric valve.

図４において、予作動弁制御盤３６の制御部１００は、操作部１０２の操作に基づき、ステップＳ１（以下「ステップ」は省略）で、操作部１０２で指定した防護区画の交換用電動弁７４に閉制御信号を出力して閉制御し、開閉検出器７６による閉検出信号を受信した場合に閉制御信号の出力を停止する。   In FIG. 4, the control unit 100 of the pre-actuated valve control panel 36 is based on the operation of the operation unit 102, and in step S <b> 1 (hereinafter, “step” is omitted), the replacement motor valve 74 for the protection section designated by the operation unit 102. When the closing detection signal is received by the opening / closing detector 76, the output of the closing control signal is stopped.

続いてＳ２で運用停止スイッチ１１０のオン操作となる運用停止操作による入力を検出すると、Ｓ３でスイッチ注意灯を点灯し、また、一定間隔で注意警報音の出力を繰り返す。   Subsequently, when an input by an operation stop operation that turns on the operation stop switch 110 is detected in S2, a switch caution light is turned on in S3, and output of a caution alarm sound is repeated at regular intervals.

続いてＳ４で作動用電動弁５０に対する信号線の取り外しで断線を検出し、Ｓ５で交換中の防護区画であることを検出するとＳ６に進んで断線警報を禁止し、一方、交換中の防護区画でなければＳ７に進んで断線警報を出力する。   Subsequently, in S4, disconnection is detected by removing the signal line from the actuating motor operated valve 50, and if it is detected in S5 that the protection zone is being replaced, the process proceeds to S6 and the disconnection alarm is prohibited. Otherwise, the process proceeds to S7 and a disconnection alarm is output.

また、Ｓ８で防護区画の火災検出と減圧検出を判別した場合、Ｓ９で交換中の防護区画であることを検出するとＳ１０に進んで作動用電動弁５０の開制御を禁止し、一方、交換中の防護区画でなければＳ１１に進んで作動用電動弁５０の開制御を行う。   Further, when it is determined in S8 that the fire detection and the decompression detection have been made in the protection section, if it is detected in S9 that the protection section is being replaced, the process proceeds to S10 to prohibit the opening control of the actuating electric valve 50, while the replacement is being performed. If it is not the protection zone, the process proceeds to S11 and the opening control of the motor operated valve 50 is performed.

続いて、Ｓ１２で運用停止スイッチ１１０のオフ操作となる運用停止解除操作の入力を検出すると、作動用電動弁５０の交換作業が完了したと判断してＳ１３に進み、交換用電動弁７４を開制御し、また、Ｓ１４でスイッチ注意灯を消灯すると共に断線警報禁止を解除する復旧処理を行って通常の監視制御に移行する。   Subsequently, when an input of an operation stop release operation that turns off the operation stop switch 110 is detected in S12, it is determined that the replacement operation of the operating motor operated valve 50 is completed, and the process proceeds to S13, where the replacement motor operated valve 74 is opened. In step S14, the switch warning light is turned off and a restoration process for canceling the disconnection alarm prohibition is performed to shift to normal monitoring control.

［交換用仕切弁を用いた予作動弁装置］
図５は交換用仕切弁を設けた予作動弁装置の実施形態を示した説明図である。図５に示すように、本実施形態の予作動弁装置２４は、作動用電動弁５０と主弁４２のシリンダ室４４を結ぶ配管に交換用仕切弁７８を設け、手動操作により開閉可能としている。 [Pre-actuated valve device using replacement gate valve]
FIG. 5 is an explanatory view showing an embodiment of a pre-acting valve device provided with a replacement gate valve. As shown in FIG. 5, the pre-actuating valve device 24 of the present embodiment is provided with a replacement gate valve 78 in a pipe connecting the operating electric valve 50 and the cylinder chamber 44 of the main valve 42 and can be opened and closed by manual operation. .

交換用仕切弁７８は通常は開放位置に操作しており、作動用電動弁５０が故障して交換する際に閉鎖位置に操作し、これにより故障した作動用電動弁５０を新品と交換するために取り外しても、シリンダ室４４の加圧水が作動用電動弁５０を取り外した配管部分から排出されて閉駆動されることを阻止する。   The replacement gate valve 78 is normally operated to the open position, and is operated to the closed position when the operating motor-operated valve 50 is failed and replaced, so that the faulty motor-operated valve 50 is replaced with a new one. Even if it is removed, the pressurized water in the cylinder chamber 44 is prevented from being discharged from the piping part from which the motor operated valve 50 is removed and driven to close.

また、交換用仕切弁７８には例えばリミットスイッチを用いた開閉検出器８０を設け、全開又は全閉を検出し、予作動弁制御盤３６の表示部に開閉状態を表示させている。   The replacement gate valve 78 is provided with an open / close detector 80 using a limit switch, for example, to detect full open or full close, and display the open / closed state on the display unit of the pre-actuated valve control panel 36.

また、交換用仕切弁７８と作動用電動弁５０の直列接続に対し手動起動弁５４を並列接続しており、交換用仕切弁７８を閉操作した状態で故障した作動用電動弁５０を取り外した状態であっても、必要に応じて手動起動弁５４を開操作することで、シリンダ室４４の加圧水を排水して主弁４２を開駆動可能としている。   Further, the manual start valve 54 is connected in parallel with the series connection of the replacement gate valve 78 and the motor operated valve 50, and the faulty motor operated valve 50 is removed while the replacement gate valve 78 is closed. Even in the state, by opening the manual start valve 54 as necessary, the pressurized water in the cylinder chamber 44 can be drained and the main valve 42 can be driven to open.

それ以外の予作動弁装置２４の構成及び機能は図２の実施形態と同じになることから、同じ符号を付してその説明を省略する。   Other configurations and functions of the pre-actuating valve device 24 are the same as those in the embodiment shown in FIG.

また、図３に示した予作動制御盤３６の制御部１００による制御は、交換用電動弁７４の開制御と閉制御を除いた制御機能と同じになる。これに対応して図４の予作動弁制御盤の監視制御を示したフローチャートは、Ｓ１及びＳ１３を除いたと同じ制御となる。   Further, the control by the control unit 100 of the pre-operation control panel 36 shown in FIG. 3 is the same as the control function except for the opening control and the closing control of the replacement electric valve 74. Correspondingly, the flowchart showing the monitoring control of the pre-actuated valve control panel in FIG. 4 is the same control as that except S1 and S13.

このように手動操作により開閉する交換用仕切弁７８を設けたことで、現場での開閉操作となるが、交換用電動弁に比べ、設備構成を簡単にしてコストを低減できる。   By providing the replacement gate valve 78 that can be manually opened and closed in this way, the on-site opening and closing operation is performed. However, compared to the replacement electric valve, the equipment configuration can be simplified and the cost can be reduced.

［本発明の変形例］
（交換用電磁弁）
図２及び図５の実施形態では、モータ駆動により開閉する交換用電動弁７４を用いた場合を例にとっているが、オンオフ的な開閉動作を行う電磁弁を用いるようにしても良い。電磁弁はソレノイドに対する通電により開放し、通電を切ることで閉鎖することができ、モータ駆動を行う電動弁に比べ、コスト的に安価であり、また耐久性も高いといえる。 [Modification of the present invention]
(Replacement solenoid valve)

The solenoid valve can be opened by energizing the solenoid, and can be closed by de-energizing, so that it can be said that it is less expensive and more durable than an electric valve that drives a motor.
