EZH（彈簧關(guān)閉式）和 EZHSO（彈簧開啟式）系列調(diào)壓器是先導(dǎo)式壓力平衡型軟閥座調(diào)壓器。 這兩種調(diào)壓器用于高壓天然氣輸送/城市門站、大流量分輸系統(tǒng)和發(fā)電廠的氣源供應(yīng)。 它們具有運(yùn)行平穩(wěn)可靠、關(guān)斷嚴(yán)密和使用壽命長等優(yōu)點。廣州奧麗斯特燃?xì)庠O(shè)備有限公司是美國FISHER產(chǎn)品華南區(qū)域（廣東省）艾默生集團(tuán)授權(quán)代理商。2020美國FISHER技術(shù)選型020*叁貳貳0162張S中國費(fèi)希爾調(diào)壓網(wǎng)www.zgfisher.com 【張工15876552411手機(jī)同微XIN】

功能

無大氣排放—利用先導(dǎo)式控制系統(tǒng)將所有氣體排放至下游系統(tǒng)，因此不會將任何有害廢氣排放至空氣中。

氣密切斷—銳利的金屬塞和軟閥座提供氣密切斷，可用于終端系統(tǒng)等需要正壓關(guān)閉的應(yīng)用。

在嚴(yán)酷的工況下具有很長的使用壽命—金屬塞設(shè)計可使顆粒和碎屑偏離軟閥座，提供的顆粒侵蝕阻力，延長使用壽命。

故障模式選項—可以利用 EZHSO 型彈簧開啟式設(shè)計實現(xiàn)**長的正常運(yùn)行時間，利用 EZH 型彈簧關(guān)閉式設(shè)計保護(hù)下游資產(chǎn)。 對很多客戶來說，通過 EZHSO 型調(diào)壓器和 EZH 型監(jiān)測器融合這兩種技術(shù)可以讓這兩種裝置發(fā)揮出**功效。

壓力控制—無論負(fù)載或入口壓力如何變化，都能夠提供穩(wěn)定、的下游壓力控制。

安靜運(yùn)行—Whisper Trim™ 閥籠選件可以降低多達(dá) 8 dBA 的源頭噪聲，因此無需投入大量成本進(jìn)行管路處理，例如絕緣、埋閥和使用只會屏蔽噪聲的外殼。

完整的壓力等級—1500 psig/103 bar 相等的入口和出口壓力等級，更易選擇，無需特殊的啟動或關(guān)閉程序。

集成式快速切斷配置—當(dāng)出現(xiàn)過壓和失壓時，EZHOSX 和 EZHSO-OSX 型通過關(guān)閉氣體停止供氣。

EZH (Spring-to-Close) and EZHSO (Spring-to-Open) Series regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in high pressure natural gas transmission/city gate stations, large capacity distribution systems, and power plant feeds. They provide smooth, reliable operation, tight shutoff and long life.

Features

Absolutely No Atmospheric Bleed—Eliminates nuisance and wasteful bleed gas to atmosphere by utilizing a pilot-operated control system, which bleeds of the gas to the downstream system.

Bubble-Tight Shutoff—A knife-edged metal plug and soft seat provide bubble tight shutoff for use in applications where positive shutoff is required such as dead-end systems.

Long Life in Severe Service Applications—The metal plug design deflects particles and debris away from the soft-seat, which gives excellent particle erosion resistance, prolonging service life.

Failure Mode Options—The Type EZHSO spring-to-open design can be utilized to maximize uptime while the Type EZH spring-to-close design can be utilized to protect downstream assets. For many customers, combining the two technologies with a Type EZHSO worker and Type EZH monitor incorporates the best of both worlds.

Precise Pressure Control—Provi**ble and accurate downstream pressure control regardless of load changes or inlet pressure variations.

Quiet Operation—The Whisper Trim™ Cage option reduces noise by up to 8 dBa at the source, eliminating the need for expensive path treatments such as insulation, buried valves, and enclosures which only mask noise.

Full Pressure Rating—The equal inlet and outlet pressure rating of 1500 psig / 103 bar, which allows easier selection and requires no special startup or shutdown procedures.

Integral Slam Shut Configurations—Types EZHOSX and EZHSO-OSX discontinue gas service by shutting the gas off if there is an overpressure or underpressure condition.
