压力释放阀说明书中英
压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等，用来保护油箱。
当油浸式变压器在运行中出现故障时，由于线圈过热，使一部分变压器油汽化，变压器油箱中压力迅速增加，这时压力释放阀在2ms内迅速动作，释放压力，保护油箱不致变形或爆裂。油箱内的压力再升高而达到开启压力时，压力释放阀应再次动作，直到油箱内的压力降到正常值。由于压力释放阀动作后能可靠关闭，油箱外的水和空气不能进入油箱，变压器内部不会受大气污染。
The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ reference.

1.Application andperformance
Pressure release valves play avital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture?Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremelyrapid build-up of gaseous pressure?If mounting this type pressure release device on the oil-tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.

For prolonged exposure to concentrated brines, or strong mineral acids, consider the severe service coating.Severe Service CoatingFor situations demanding the highest corrosion resis-tance, consider the severe service coating.the body of the marsh hawk is coated with a red Fusion Bond epoxy (FBe) for resistance to mineral acids,(including sulphuric and hydrochloric acids up to 15%) high-chloride ion solutions (including alumi-num chloride, potassium chloride and brine) as well as many other petrochemicals.the marsh hawk internals are coated in a proprietary black PFa (teFLOn) providing the same excellent fluo-ropolymer chemical resistance as the FBe above.series 4000 marsh hawk trv with manual relief Optionseries 4000 marsh hawk trv with hard anodizationseries 4000 marsh hawk trv with severe service coatingO P T I O N S A N D AC C E S S O R I E S (C O N T I N U E D )S E A L C O N F I G U R AT I O N A N D M AT E R I A L S the series 4000 marsh hawk combines the pressure and vacuum valve in an innovative design that requires only one shared gasket.to improve valve sealing performance, gaskets are factory coated with a pliable silane-based sealant. an optional oil-based sealant for use in sour gas applica-tions is also available. Both sealants are available in small packages for maintenance and reapplication.hawkeye offers three material options for the pressure / vacuum seal, beyond the standard Fkm (viton®) seal.• For applications where sealing is the first priority and the vent is not expected to operate often and has low set pressures (under 4 ozsi), eFkm (sponge viton®) can be supplied.• For higher temperature, minimally freezing conditions and acid service FePm (aflas®) is available.• For extreme applications FFkm (kalrez®) is also available.the use of ePDm seals in any hawkeye vent is contra-indicated due to its unsuitability in common petrochem-ical applications.hawkeye does not offer or recommend using solid fluoropolymer (PtFe, PFa, FeP, etc.), nor expanded flu-ropolymer (gOre-tex®) as a gasket material and any venting device. although the material may be chemi-cally suitable, the harder crystalline polymer structure of these materials impedes sealing at the typically low interfacial pressures found in the marsh hawk, as well as other low-pressure (i.e. <15 psi) vents.GENE R A L FLU OROEL A STOM E R CHEM ICA L C OM PATI BI LI T Y¹FKM / VI TON N.B.¹ THIS CHART I S F OR R EFE REN CE ONLY.

The minimum pressure drop is obtained when the pilot valve is also de-energized . The total pressure drop through the venting 2-way valve and pipework is additive to the pressure at P . While the valve is vented the system pressure cannot be controlled via the proportional solenoid . This control feature is frequently used during off-load periods in machine cycle times . If lower off-load system pressures are required then additional full flow unloading valves are recommended, e .g . Vickers™ CV series cartridge valves .

For effective protection the user electrical cabinet, the valve subplate or manifold and the cable screens should be connected to efficient ground points. The metal 7 pin connector part no. 934939 should be used for the integral amplifier. In all cases both valve and cable should be kept as far away as possible from any sources of electromagnetic radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. Difficult environ-ments could mean that extra screening may be necessary to avoid the interfer-ence. It is important to connect the 0V lines as shown above. The multi-core cable should have at least two screens to separate the demand signal and monitor output from the power lines. The enable line to pin C should be outside the screen which contains the demand signal cables.User Panel shellKB..

压力释放阀PRESSURE RELEASE VALVE使用说明书OPERATION INSTRUCTION明远电器设备SHENYANG MINGYUAN ELECTRIC EQUIPMENT CO., Ltd.本说明书适用于我公司生产的系列变压器用压力释放阀，阐述其用途、性能、规格、技术参数、使用及安装，供用户参考。
The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ reference.1. 压力释放阀用途和性能压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等，用来保护油箱。
当油浸式变压器在运行中出现故障时，由于线圈过热，使一部分变压器油汽化，变压器油箱中压力迅速增加，这时压力释放阀在2ms迅速动作，释放压力，保护油箱不致变形或爆裂。
油箱的压力再升高而达到开启压力时，压力释放阀应再次动作，直到油箱的压力降到正常值。
由于压力释放阀动作后能可靠关闭，油箱外的水和空气不能进入油箱，变压器部不会受大气污染。
1.Application and performancePressure release valves play a vital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture? Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremely rapid build-up of gaseous pressure? If mounting this type pressure release device on the oil-tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.2．型号、规格及基本参数Type, specification and technical parameters2.1 型号的含义 Meaning of typeY S F□—□ / □□□特殊环境代号（Special environment）带机械信号标“J”（“J”：mechanical signal）带信号开关标“K”（“K”：electrical signal）两者都带标“KJ”（“KJ”：Both with signal）喷油有效口径（Caliber of oil-gushing tube）mm开启压力（Opening pressure）kPa设计序号（Design serial number）阀（valve）释放（release）压力（pressure）注：特殊环境代号 note: special environment:TA: 干热带地区 dry tropicTH: 湿热带地区 humid tropicT: 干、湿热带地区 dry、humid tropic例：YSF16-55/130KKJT开启压力为55kPa，喷油口径为φ130mm，带电信号、机械信号。
