Umhlahlandlela Wezihlalo Zamavalvu Ebhola: Isikhali Esiyimfihlo Sesivikelo Sakho

Umhlahlandlela Wesihlalo Se-Ball Valve: Imisebenzi, Izinto Ezisetshenziswayo (Isihlalo se-PTFE Nokunye) kanye Nobubanzi Bokushisa | I-Ultimate Seal

Ezweni le-amavalvu ebhola, ukuvala okuphumelelayo kubaluleke kakhulu. Ingqikithi yalo msebenzi obalulekile iyingxenye ebalulekile:Isihlalo se-Ball Valve, ngokuvamile ibizwa ngokuthiIsihlalo SevalvuLeli qhawe elingadunyiswanga liyiqhawe langempela "lokuvala" lenhlangano ye-Ball Valve.

Iyini ngempela isihlalo se-Ball Valve

IIsihlalo se-Ball Valvekuyinto ebalulekile yokuvala ngaphakathi kwe-ivalvu yebholaisakhiwo. Ngokuvamile senziwe ngezinto zensimbi noma ezingezona ezensimbi, sifakwa ngaphakathi komzimba wevalvu. Indima yaso eyinhloko ukwakha isikhombimsebenzisi sokuvala esiqinile nebhola elijikelezayo. Ngokugcina lokhu kuxhumana okuseduze,Isihlalo Sevalvuivumela ivalvu ukuthi ivale noma ilawule ukugeleza koketshezi ngokuthembekile.

Usongo Oluthathu Lwesihlalo Se-Valve: Okungaphezu Kophawu Nje

YesimanjeIzihlalo ze-Ball Valvezinamakhono amangalisayo ngale kokuvala okuyisisekelo:

1. Ukuvala Okuguquguqukayo (I-Shape-Shifter):Njengomcamelo we-memory foam ohambisana nekhanda lakho, i-Valve Seat esezingeni eliphezulu igcina ukuguquguquka kuzo zonke izinga lokushisa eliphakeme (kubhekisela ezindinganisweni ze-ASTM D1710, ngokuvamile -196°C kuya ku-+260°C). Lokhu kuguquguquka kuyivumela ukuthi ikwazi ukukhokhela ngokuzenzakalelayo ukuguguleka okuncane ebusweni bebhola, okuqinisekisa ubuqotho bokuvala isikhathi eside.

2. Umqondisi We-Fluid (Umvikeli):Imiklamo eklanywe ngokukhethekile, njenge-V-port Ball Valve Seats, iqondisa ngenkuthalo indawo egelezayo. Lokhu kugeleza okuqondisiwe kusiza ekuhloleni izindawo zokuvala, kuvimbele ukwakheka kwemfucumfucu noma izinto ezincane ezingalimaza uphawu.

3. Isiphenduli Esiphuthumayo (Ukuphepha Komlilo):Imiklamo ethile yeSihlalo seValve inezici ezivikela umlilo. Uma kwenzeka ukushisa okukhulu (njengomlilo), lezi zihlalo zenzelwe ukusha noma ukwenza i-carbon. Lolu ngqimba olufakwe i-carbon bese lwakha uphawu lwesibili, oluphuthumayo oluvela kunsimbi luye kunsimbi, oluvimbela ukwehluleka okukhulu.

Isayensi Yokuvala: Indlela Isihlalo Sevalvu Esisebenza Ngayo

Ukuvala kwenzeka ngokucindezela okuqondile ngokomzimba. Uma ibhola lijikeleza liye endaweni evaliwe, licindezela ngokuqinile ngokumeleneIsihlalo se-Ball Valve. Lo mfutho ushintsha kancane isihlalo, udale isithiyo esiqinile esivimbela ukuvuza. Amavalvu ebhola ajwayelekile asebenzisa izihlalo ezimbili zamavalvu - esinye esisekungeneni kanye nesinye ohlangothini lokuphuma. Esimweni esivaliwe, lezi zihlalo "ziyagona" ibhola ngempumelelo, zikwazi ukumelana nokucindezela okufika ku-16MPa (ngomuntu ngamunye)Izindinganiso ze-API 6D). Imiklamo ethuthukisiwe, njengezihlalo ze-V-port, ingathuthukisa kakhulu ukuvala ngokusebenzisa amandla okusika alawulwayo asebenza kumidiya.

Amazinga Okushisa Esihlalo Se-Ball Valve: Izinto Ezibalulekile

Imikhawulo yokushisa yokusebenza ye-Isihlalo se-Ball Valvengokuyinhloko kunqunywa ukwakheka kwezinto ezisetshenziswayo. Nansi incazelo yezinto ezisetshenziswa ezivamile zesihlalo kanye nobubanzi bazo obubalulekile bokushisa:

Izihlalo ze-Soft Seal Ball Valve (ezisekelwe ku-Polymer & Elastomer):

•Isihlalo se-PTFE (i-Polytetrafluoroethylene):Ukukhetha okujwayelekile. Izihlalo ze-PTFE zisebenza kahle kakhulu ekumelaneni nokugqwala futhi zisebenza ngokuthembeka phakathi-25°C kuya ku-+150°C. Ngezinhlelo zokusebenza ezidinga ukujikeleza njalo, i-PTFE enziwe ngomshini onembileIzihlalo (ezifinyelela ukubekezelelana okungu-±0.01mm) ezihlanganiswe namabhola aqediwe ngokukhethekile zingaletha imijikelezo engaphezu kuka-100,000 ngaphandle kokuvuza - zihlangabezana nezindinganiso eziqinile ze-ISO 5208 Class VI.

• I-PCTFE (i-Polychlorotrifluoroethylene):Ilungele izinsizakalo ze-cryogenic. Isebenza kahle kusukela-196°C kuya ku-+100°C.

• I-RPTFE (i-PTFE Eqinisiwe):Ithuthukisiwe ukuze ihlale isikhathi eside futhi ikwazi ukumelana namazinga okushisa aphezulu. Uhla olufanele:-25°C kuya ku-+195°C, kuhle kakhulu ekusetshenzisweni kwe-high cycle.

• I-PPL (i-Polyphenylene):Umdlali oqinile we-steam. Sebenzisa ngaphakathi-25°C kuya ku-+180°C.

• I-Viton® (i-FKM Fluoroelastomer):Idume ngokumelana namakhemikhali kanye nekhono lokushisa elibanzi (-18°C kuya ku-+150°CSebenzisa ngokucophelela ngomusi/amanzi.

• I-Silicone (VMQ):Inikeza ukufinyelela okuphezulu kakhulu ekushiseni kanye nokungangeni kwamakhemikhali (-100°C kuya ku-+300°C), ngokuvamile kudinga ukwelashwa ngemva kokwelashwa ukuze kutholakale amandla afanele.

• I-Buna-N (Irabha ye-Nitrile – NBR):Inketho eguquguqukayo nengabizi yamanzi, uwoyela, kanye namafutha (-18°C kuya ku-+100°C). Ukumelana okuhle nokuklwebheka.

• I-EPDM (i-Ethylene Propylene Diene Monomer):Kuhle kakhulu ekumelaneni ne-ozone, ekushiseni kwesimo sezulu, kanye nasekusetshenzisweni kwe-HVAC (-28°C kuya ku-+120°CGwema ama-hydrocarbon.

• I-MOC / MOG (Ama-PTFE Composites Agcwele Ikhabhoni):Inikeza ukuzinza okuthuthukisiwe kanye nokumelana nokuguguleka. I-MOC/MOG ivame ukuba nobubanzi obuhlukahlukene-15°C kuya ku-+195°C.

• I-MOM (i-PTFE Egcwele Ikhabhoni Eguquliwe):Kwenzelwe ukugqokwa, ububanzi-15°C kuya ku-+150°C.

• I-PA6 / I-PA66 (Inayiloni):Kuhle ekucindezelweni nasekugugeni (-25°C kuya ku-+65°C).

• I-POM (i-Acetal):Amandla aphezulu nokuqina (-45°C kuya ku-+110°C).

• HLOLA (i-Polyetheretherketone):I-polymer ephezulu esebenza kahle kakhulu. Izinga lokushisa elimangalisayo (-50°C kuya ku-+260°C), ingcindezi, ukuguguleka, kanye nokumelana namakhemikhali. Imelana kakhulu ne-hydrolysis (amanzi ashisayo/umusi).

Izihlalo ze-Hard Seal Ball Valve (Esekelwe ku-Metal & Alloy):

• Insimbi Engagqwali + I-Tungsten Carbide:Isixazululo esiqinile samazinga okushisa aphezulu (-40°C kuya ku-+450°C).

• I-Hard Alloy (isb, i-Stellite) + Ni55/Ni60:Ukuguguleka okuphezulu kanye nokumelana nokushisa okukhulu (-40°C kuya ku-+540°C).

• I-Alloy Yokushisa Okuphezulu (isib., i-Inconel, i-Hastelloy) + i-STL:Yenzelwe izinsizakalo ezinzima kakhulu (-40°C kuya ku-+800°C).

Ukucatshangelwa Okubalulekile:Izinto ezibalwe ngenhla zimelela izinketho ezivamile.Isihlalo se-Ball Valveukukhetha kumele kusekelwe ku-izimo zokusebenza ezithile(izinga lokushisa, ingcindezi, isilinganiso, imvamisa yomjikelezo, njll.) yesicelo ngasinye. Kukhona ezinye izinto eziningi ezikhethekile ukuze kuhlangatshezwane nezidingo ezihlukile ngale nje kokushisa. Njalo xhumana nabakhiqizi bama-valve ukuze uthole izincomo zezinto eziqondile ezenzelwe uhlelo lwakho. IlungeloIsihlalo Sevalvukubalulekileivalvu yebholaukusebenza kanye nokuphila isikhathi eside.
