DL Sentinel Hom CH Reset Safety Valve

Lub NOV Hom CH rov pib dua kev nyab xeeb valve siv qhov kev tsim kho tshuab / hydraulic siab tshaj plaws kom ua tiav "tsis siv neeg rov pib dua" muaj nuj nqi yam tsis muaj kev cuam tshuam los ntawm phau ntawv, uas ua rau nws yooj yim dua li ib txwm siv - lub sij hawm siab nyem.

Tsis siv neeg rov pib dua mechanism: goodbye rau tus pin shear (H3)

Lub siab nyem mechanism ntawm Hom CH valve yog raws li qhov sib npaug ntawm qhov system hydraulic siab thiab cov khoom siv rov ua haujlwm sab hauv.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm: Lub hydraulic siab nyob rau hauv lub kaw lus ncaj qha ua rau lub pob thiab valve lub rooj zaum mechanism 1. Thaum lub kaw lus siab qis dua tus nqi teev, lub pob tseem nyob hauv txoj hauj lwm los tiv thaiv cov dej ntws.

Kev ua kom muaj kev ntxhov siab: Thaum lub raj xa dej siab tshaj qhov preset tus nqi, tus kheej kheej pib tawm ntawm lub rooj zaum valve (unseat), thiab cov kua dej ntau dhau los ntawm lub qhov hluav taws xob.

Rov pib dua: Tom qab lub siab nyem, Hom CH valve yog tus kheej - rov pib dua 1. Lub caij nplooj ntoos hlav disc tau teeb tsa hauv lub valve. Thaum lub overpressure raug tshem tawm, lub disc caij nplooj ntoos hlav mechanism tuaj yeem xyuas kom meej tias lub valve sai sai rov qab mus rau lub rooj zaum thiab foob, thiab rov qab mus rau lub xeev ua haujlwm.

Tsis siv neeg tsim: Thaum ntxov Retsco Titan Class "CH" valve (uas yog siv) siv lub siab sib npaug chamber (siab sib npaug chamber) rau throttle kua los ntawm qhov chaw nres nkoj piston kom ua tiav hydraulic buffering, yog li smoothing qhib lub suab ntawm lub piston.

Sib piv nrog cov cuab yeej siv tshuaj tua kab mob (H3)

Ib txwm shear pin (Shear Pin) los yog rupture disc (Rupture Disc) kev nyab xeeb li qub yuav tsum manually hloov cov khoom puas tom qab siab nyem, thaum lub tsis siv neeg rov pib feature ntawm hom CH valve ncaj qha tshem tawm qhov mob taw tes.

Chav kawm siab thiab bore range (H3)

NOV txoj kab ntawm lub siab nyem li qub npog cov kev xav tau siab tshaj plaws hauv kev lag luam roj thiab roj.

Hom CH series ntsig txog siab ntau:

Titan C / B Series: Kev ntsuas siab ntawm 400 psi txog 5000 psi.

Titan RX Series: Kev ntsuas siab ntau ntawm 2,000 psi txog 8,000 psi.

Anson ™ siab siab valve (tus qauv kev pabcuam): ua haujlwm siab txog 20,000 psi (Fig 2002).

Anson ™ siab siab valve (nrog rau kev pabcuam sulfur): ua haujlwm siab txog 15,000 psi (Daim duab 2202).

Qhov ntau thiab tsawg: Lub NOV siab - cov khoom siv hluav taws xob muaj xws li fittings tsim rau 20,000 psi kev pabcuam. Daim duab 2202 qhia tau hais tias cov hammering specifications feem ntau npog 2 ", 3", thiab 4 "qhov ntau thiab tsawg.

Khoom specification thiab adaptability rau hnyav ua hauj lwm tej yam kev mob (H3)

Hom CH li qub yog tsim los ntawm siab- cov ntaub ntawv ua tau zoo kom ntseeg tau tias muaj kev ntseeg siab hauv cov dej siab thiab corrosive (xws li sulfur- muaj H₂S ib puag ncig).

Valve lub cev khoom: feem ntau yog ua los ntawm forged steel, tuaj yeem ua raws li API 6A specifications. Siab siab li qub xav tau cov ntaub ntawv qib kev lag luam nrog lub zog tensile zoo thiab lub zog tawm los, xws li cov hlau tsis muaj steel, carbon hlau lossis cov hlau tshwj xeeb.

Sour Service (SAS):

Rau qhov hnyav ib puag ncig uas muaj leej faj (H₂S), NOV muaj NACE MR0175-ua raws li li qub xws li Fig 2202 Acid Gas Service Valve, uas ua haujlwm ntawm qhov siab txog li 15,000 psi. NACE MR0175 tus qauv tsim cov kev cai nruj rau cov ntaub ntawv zoo li cov nickel alloys thiab tshwj xeeb stainless hlau los tiv thaiv sulfide kev nyuaj siab corrosion tawg hauv H₂S ib puag ncig.

Valve internals / seals: Rau cov ntawv thov tseem ceeb uas yuav tsum tau muaj qhov kub thiab txias thiab tiv thaiv corrosion, tshwj xeeb npib tsib xee alloys xws li Inconel, Hastelloy, los yog Monel yog siv los ua valve internals. Kev xaiv cov ntsaws ruaj ruaj yuav nyob ntawm qhov kub thiab txias thiab tshuaj lom neeg cov kev xav tau kom tau raws li cov neeg siv khoom xav tau thoob plaws ntau yam dej ua haujlwm.

Kev tsim cov txheej txheem ntawm kev kub siab li qub tsom rau kev txhim kho cov kav ntev thiab kev ntseeg siab ntawm cov khoom, tshwj xeeb tshaj yog nyob rau hauv kev hnav siab thiab siab sib txawv.

Lub hauv paus tsim khoom: Lub cev tseem ceeb ntawm lub valve yog forged steel, uas muaj cov khoom siv zoo dua qub thiab kev ua haujlwm sab hauv kev ncaj ncees dua li cov khoom cam khwb cia, thiab tuaj yeem tiv taus siab.

Kev siv thev naus laus zis ntxiv rau saum npoo: txhawm rau txhawm rau txhawm rau txhawm rau hnav tsis kam ntawm qhov tseem ceeb hauv lub valve xws li lub rooj zaum thiab lub pob nyob rau hauv kev kub ceev dej scouring, cov txheej txheem hauv qab no feem ntau siv:

Stellite (Stellite) cladding: Stellite yog cobalt raws li alloy paub rau nws zoo heev hnav tsis kam, corrosion kuj thiab kub stability.

Tungsten Carbide Txheej: Cov txheej txheem no yog tsim los ntawm High-Oxygen Fuel (HVOF) txau tshuab, uas tso cov khoom carbide mus rau qhov chaw sib khi ntawm kev kub ceev. Cov txheej txheem tsim cov txheej txheem muaj zog nrog tshwj xeeb adhesion, hardness (txog 1400 HV), thiab porosity tsawg. Cov khoom no ua rau muaj txiaj ntsig zoo rau kev tiv thaiv kev yaig thiab kev hnav, ua kom muaj kev pab cuam lub neej nyob rau hauv siab - cov kua dej erosive.

Lub NOV Hom CH rov pib dua kev nyab xeeb valve yog lub hauv paus tseem ceeb ntawm kev pabcuam roj av siab thiab tsim nyog rau kev ua haujlwm uas muaj kev nyab xeeb thiab txuas ntxiv siab heev.

• Fracturing / Stimulation: Hauv cov ntawv thov xws li shale gas, kev kub siab tawg twj tso kua mis tsheb thauj khoom siv siab heev rau txoj kab khiav 1. Hom CH valve ua raws li qhov kawg kev nyab xeeb thaiv kev tiv thaiv lub twj tso kua mis thiab cov kab ntws los ntawm kev kub siab tam sim ntawd.
• Pressure Controlling Drilling (MPD): Hom CH valve yog siv nyob rau hauv lub siab tswj qhov drilling system los tiv thaiv kev raug mob los ntawm kev tso siab, thiab nws cov yam ntxwv rov qab sai sai pab txo tag nrho tsis yog - lub sij hawm tsim khoom (NPT) ntawm drilling.
• Acidizing thiab cementing: Cov haujlwm no suav nrog cov kua dej corrosive thiab cov twj tso kua mis siab, thiab cov li qub yuav tsum tau tiv thaiv cov xov xwm nyuaj, qhov twg Hom CH's corrosion kuj plays lub luag haujlwm tseem ceeb.
• Kev tiv thaiv kev nyab xeeb ntawm lub taub hau: siv los tiv thaiv tsob ntoo Christmas, ntsuas qhov sib cais thiab cov yeeb nkab hanger system los ntawm kev hloov pauv siab thaum lub sij hawm siv los yog ntau lawm kom ntseeg tau tias kev ncaj ncees ntawm tag nrho cov kab ke.
