安全閥是啟閉件受外力作用下處于常閉狀態，當設備或管道內的介質壓力升高超過規定值時，通過向系統外排放介質來防止管道或設備內介質壓力超過規定數值的特殊閥門。安全閥屬于自動閥類，主要用于井口壓力容器和管道管線上，控制壓力不超過規定值，對人身安全和設備運行起重要保護作用。
2017年3月20日-22日，一家專門生產井口安全閥與驅動器的高科技企業——賽科（深圳）能源設備有限公司 Safoco China（以下簡稱“賽科能源”展位號：W1582）將在北京·中國國際展覽中心（新館）舉行的cippe2017第十七屆中國國際石油石化技術裝備展覽會亮相，向專業觀眾展示其專業優秀的安全閥與自動化井口控制等設備。
FRV簡介：
Safoco壓裂安全閥（FRV）結合了創新技術與有良好信譽的安全性于一體，這個FRV是市場上第一個以全通徑、不間斷提供泄壓流體等特性的安全閥。它可實現迅速泄壓，防止給閥門造成磨損和破壞，同時其配備了Safoco的安全自動監控儀器（SAMI）可以保持壓裂作業的網上在線操作，FRV被Safoco智能的技術所控制，能讓使用者通過數字化錄入出油管線的壓力、記錄和監控活動并且遠程操作閥門；手輪驅動器的功能性和幾個報警裝置提供了額外的安全性； F R V整套設備包括：15000 PSI API 閥門、API促動器、2 "，3 " 或者4 "1502高壓接頭和備用電池；配備的Safoco的液壓驅動器被設計為當安全閥情況最緊急時，允許閥門中的壓力來協助驅動器釋壓，以便在更高壓時能更迅速地打開閥門泄壓。
FRV1和FRV-2
Safoco’s Fracturing Relief Valve (FRV) combine sinnovative technology with reputable safety. The FRV is the first relief valveon the market featuring full bore, un-interrupted flow relief. This allows for immediaterelief, prevents wear and tear to the valve, while also keeping fracturing operationsonline. The FRV is controlled by Safoco’s smart technology, allowing the userto digitally enter flow line relief pressure, record and monitor activity, and operatevalves remotely. Manual override functionality and several alert features provideadditional safety. The FRV features: 15,000 PSI API valve; API actuator; 2”,3”, or 4” 1502 Hammer Union connections, and battery back-up.
Safoco’s Safety Automated MonitoringInstrument (SAMI) allows for the monitoring and operation of an actuated valveonsite. The SAMI is able to provide alarm notifications and remote verificationof both the safety system and valve integrity on a regular basis.
The Safoco Hydraulic Actuated Valveutilizes wellhead safety valve technology and applies it to the hydraulicfracturing industry. The hydraulic actuator is designed to allow the pressurein the valve to assist in the relieving process and open the valve quicker athigher pressures, when the relief valve is most critical.
SAMI簡介：
SAMI是一套自足自動緊急關閉系統，配備氣動/液動驅動器，應用于井口閥門和管道 ESD 閥門設備；其使用低功耗微處理器監控各種壓力、溫度和其它信號，控制閥門驅動。還可通過人機界面實現遠程控制這些命令。它使用一種數據采集和監測控制（SCADA）協議跟已存在數據結構或Safoco數據庫-ESD 閥門系統通信。在極其偏遠地區使用銥衛星系統、蜂窩通訊系統或現有的遠程終端設備（RTU）與SCADA實現通信；SAMI 可適應于各種井口和管道傳感器，包括壓力、溫度、液面、電子砂探針、硫化氫探測器、火警、閥位傳感器等；其定期監測和檢查自身電量，當低電量時它會關閉 ESD 閥門并發送警報，該控制系統通常配備太陽能和/或風力發電系統，Safoco使用特定的太陽能電池一般使用3-5年。
SAMI1和SAMI-2
The SAMI system (Safety Automated Monitoring Instrument) is a self-contained autonomous emergency shutdown system for wellheadvalves and pipeline ESD valve applications when equipped with pneumatic orhydraulic actuators.
The SAMI achieves this by using very lowpower microprocessors to monitor a variety of pressures, temperatures, and othersignals to control valve actuation. These commands can be controlled remotelyvia HMI. If there is not an alarm, the SAMI can close and open an emergencyshut-down valve remotely to verify the integrity of the ESD system.
The SAMI uses a SCADA (Supervisory Controland Data Acquisition) protocol to communicate to either an existing datainfrastructure or to SAFOCO’s data warehouse – ESD Valve Scape. Communicationis accomplished through Iridium Satellite systems in extremely remote areas,cellular communication systems, or existing RTU (Remote Terminal Units) SCADA systemswhere available.
The SAMI controller is flexible in its input and output structure to accommodate a variety of wellhead and pipelinesensors. This includes multiple pressures, temperatures, fluid levels, electronicsand probes, H2S detectors, fire alarms, valve position sensors, and a number of internal functional and diagnostic inputs – such as battery monitoring,hydraulic levels sensors, and hydraulic or pneumatic pressure sensors, dependingon the type of valve actuation. The SAMI continuously monitors its own condition by checking its battery level. SAMI will close the ESD valves andsend an alarm in case of the battery falling below safe levels.
The SAMI control system is typically supplied with a solar and/or wind generator charging systems sized to suit thesystem parameters and the environmental conditions of installation. SAFOCO Inc.uses specific duty solar batteries, having typical battery life of 3-5 years.
