安全閥是啟閉件受外力作用下處于常閉狀態(tài)，當(dāng)設(shè)備或管道內(nèi)的介質(zhì)壓力升高超過(guò)規(guī)定值時(shí)，通過(guò)向系統(tǒng)外排放介質(zhì)來(lái)防止管道或設(shè)備內(nèi)介質(zhì)壓力超過(guò)規(guī)定數(shù)值的特殊閥門。安全閥屬于自動(dòng)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(guò)規(guī)定值，對(duì)人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。

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.

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.
