Iivalvu zokuvala ezingxamisekileyo (ESDV)

Yintoni iI-ESDVs

Iivalvu zokuvala ngexesha likaxakekaZonke zinomsebenzi wokuvala ngokukhawuleza, ngesakhiwo esilula, impendulo ebukhali, kunye nesenzo esithembekileyo. Ingasasazwa ngokubanziIsetyenziswa kumacandelo emveliso yemizi-mveliso efana nepetroleum, iikhemikhali, kunye ne-metallurgy. Umthombo womoya wevalvu yokusika umoya ufuna umoya ocinezelweyo ohluziweyo, kwaye i-medium ehamba emzimbeni wevalvu kufuneka ibe lulwelo kunye negesi ngaphandle kokungcola kunye namaqhekeza. Uhlu lweevalvu zokuvala umoya: iivalvu eziqhelekileyo zokuvala umoya, iivalvu zokuvala umoya ezikhawulezayo.

Ipharamitha yokusebenza ye-EI-SDV

Ivalvu yokusika i-pneumatic isebenzisa isakhiwo sokuvala esithambileyo, esiyilwe ngokutywina okusebenzayo kunye nokugcinwa kokugcina, kunye ne-torque encinci yokusebenza, umlinganiselo woxinzelelo lokuvala ophakathi, ukutywina okuthembekileyo, isenzo esibucayi, ulawulo olulula lwe-hydraulic ukufikelela kulawulo oluzenzekelayo, kunye nobomi benkonzo ende. Iivalvu zebhola zokusika i-pneumatic zisetyenziswa kakhulu kumashishini afana ne-petroleum, iikhemikhali, i-metallurgy, ukwenza iphepha, amayeza, i-electroplating, njl.

1. Uxinzelelo olusebenzayo: 1.6Mpa ukuya kwi-42.0Mpa;

2. Ubushushu bokusebenza: -196+650 ℃;

3. Iindlela zokuqhuba: ngesandla, izixhobo zemibungu, umoya ohamba emoyeni, umbane;

4. Iindlela zoqhagamshelo: umsonto wangaphakathi, umsonto wangaphandle, iflange, ukuwelda, ukuwelda kwebutt, ukuwelda kwesokhethi, umkhono, iclamp;

5. Imigangatho yokuvelisa: I-GB JB, HG, i-API ANSI esemgangathweni yaseMelika, i-BS esemgangathweni yaseBritane, i-JIS JPI yaseJapan, njl.njl.;

6. Izinto zomzimba wevalvu: ubhedu, isinyithi esixonxiweyo, isinyithi esixonxiweyo, intsimbi yekhabhoni iWCB、WC6、WC9、20#、25#、 Intsimbi eyenziweyo i-A105、F11、F22、 Intsimbi engatyiwayo, 304, 304L, 316, 316L, intsimbi ye-chromium molybdenum, intsimbi enobushushu obuphantsi, intsimbi ye-titanium alloy, njl.

Uhlobo lwe-Pneumatic Actuator lwe-EI-SDV(Iivawubhu Zokuvala Ezingxamisekileyo)

I-Pneumatic Actuator of Emergency Shutdown Valve isebenzisa uhlobo lweScotch Yoke, uhlobo lweGear Rack, uhlobo lwePiston, kunye neDiaphragm, kunye nokusebenza kabini kunye nokubuyela kwentwasahlobo (ukusebenza okukodwa).

1. I-piston ephindwe kabini yohlobo lwegiya, ene-torque enkulu kunye nomthamo omncinci;

2. Isilinda yenziwe ngezinto ze-aluminium, ekhaphukhaphu kwaye inembonakalo entle;

3. Iindlela zokusebenza ngesandla zingafakwa phezulu nasezantsi;

4. Uqhagamshelo lwe-rack kunye ne-pinion lunokulungisa i-engile yokuvula kunye nesantya sokuhamba esilinganisiweyo;

5. Isalathiso sempendulo yesignali ephilayo enokukhethayo kunye nezixhobo ezahlukeneyo ze-actuators ukuze kufezekiswe ukusebenza ngokuzenzekelayo;

6 Uqhagamshelo oluqhelekileyo lwe-IS05211 lubonelela ngokulula kokufakelwa nokutshintshwa kwemveliso;

7. Izikrufu ezilungisekayo kuzo zombini iziphelo zivumela iimveliso ezisemgangathweni ukuba zibe noluhlu olulungisekayo lwe-± 4 ° phakathi kwe-0 ° kunye ne-90 °. Qinisekisa ukuchaneka kokuvumelanisa nevalvu.

Izixhobo zeNewsway Valve Umenzi weemveliso

IUmvelisi weValve waseTshayinaukusukaiTshayina, umzimba weevalvu zayo kunye nezinto zokuhombisa zinokufumaneka ngaphakathiYenziwe ngenkohlisouhlobo kunyeUkuphosauhlobo. Ecaleni kweYenziwe ngentsimbi eshayinayokwayeIntsimbi yeCarbonizinto eziphathekayo, nathiiivalvu zokwenzakwizixhobo ezikhethekileyo ezifana ne-titanium, i-nickel alloys, i-HASTELLOY®*, i-INCOLOY®, i-MONEL®, i-Alloy 20, i-super-duplex, i-corrosion resistant alloys kunye nezixhobo ze-urea grade.
