Ukuhlelwa okuphambili kunye neemeko zenkonzo ze-valve

Ukutywinwa kweValve yinto ebalulekileyo yevali yonke, injongo yayo yeyona nto iphambili kukuthintela ukuvuza,ivalveIsihlalo sokutywina sikwabizwa ngokuba yi-ring yokutywina, ngumbutho onxibelelana ngokuthe ngqo kunye ne-Pipeliel kwipayipile kwaye uthintele iphakathi ukusuka kwi-intanethi. Xa ivalve isetyenziswa, kukho imithombo yeendaba ezahlukeneyo kumbhobho, onjengolwelo, igesi, ioyile, i-Sorrossion, kunye namatywina eevalves ezahlukeneyo zisetyenziswa kwiindawo ezahlukeneyo.

I-TWSValveKukhumbuza ukuba izixhobo zetywina ze-valve zinokwahlulwa zibe ziindidi ezimbini, ezizezi zentsimbi kunye nezinto ezingesosinyithi. Amatywina angaqhelekanga asetyenziswa ngokubanzi kwimibhobho kubushushu obuqhelekileyo kunye noxinzelelo, ngelixa amatywina entsimbi enoluhlu olubanzi lwezicelo kwaye unokusetyenziswa kubushushu obuphezulu. uxinzelelo oluphezulu.

1. Irabha ye-syntiction

Irabha ye-Syntiction ilunge ngakumbi kunerabha yendalo malunga nokuxhathisa kweoyile, ukuxhathisa kobushushu kunye nokunganyangeki. Ngokubanzi, ubushushu bokusebenza kwerabha ye-synthetic ye-t≤I-150°C, irabha yendalo ngu-t≤60°C, kunye nerabha isetyenziselwa ukutywina kwe-valves, i-valve yesango, i-dialves, iivalves, iivalves, i-valves, i-valves kunye nezinye iivalves ngoxinzelelo lwePN≤I-1mPA.

I-2. Nylon

I-NYLOLO ineempawu zolungelelwaniso oluncinci nolungelelwaniso oluhle kunye nokunganyangeki. I-NYLOLO isetyenziselwa i-valves yebhola kunye ne-globe valves kunye neqondo lobushushu t≤90°C kunye noxinzelelo olufanelekileyo pn≤I-32MPA.

3. Ipolytetrafluorororororoothylene

I-PTFe isetyenziswa kakhulu kwi-valves, i-valve yesango, i-valves, njl. Njl.≤232°C kunye noxinzelelo olufanelekileyo pn≤6.4MPA.

I-4. I-iron yentsimbi

Isinyithi sentsimbi sisetyenziselwa i-valve yesango, i-valves, i-valves, njl. Njl.≤I-100°C, uxinzelelo olufanelekileyo pn≤I-1.6MPA, igesi kunye neoyile.

I-5. I-Babbitt Alloty

I-Babbitt Alloty isetyenziselwa i-Ammonia Globe Hlobe enamaqondo obushushu T-70 ~ 150℃kunye noxinzelelo olufanelekileyo pn≤I-2.5PA.

I-6. Ubhedu

Izixhobo ezisetyenziswayo ze-noppersts zolawulo zi-6-6-3 tin no-Bronze kunye ne-58-2-2. Ubhedu Alloty unesichaso esihle kwaye ulungele amanzi kunye ne-steam ngeqondo lobushushu t≤200℃kunye noxinzelelo olufanelekileyo pn≤I-1.6MPA. Ihlala isetyenziswa ngamasango e-valves, i-valve valves, i-valves, iplanga, njl.

I-7. I-Chrome Stainess

Amabakala asetyenziswe ngentsimbi ye-chromium engacacanga abayi-2CR13 ne-3CR13, ecinyiwe, kwaye inomvuzo, kwaye ixhathise kakuhle. Ihlala isetyenziswa kwii-valves zamanzi, i-Steam kunye nepetroleum ngeqondo lobushushu t≤I-450℃kunye noxinzelelo olufanelekileyo pn≤I-32MPA.

I-8. I-Chrome-Nickel-Titanium yentsimbi

Inqanaba eliqhelekileyo le-chromium-tikel-titanium le-tikel-titanium i-1CR18NI9TI, ethi ixhathise i-corosions elungileyo, ukumelana nobushushu kunye nokuxhathisa ubushushu. Ilungele i-Steam kunye nezinye iindaba kunye nobushushu t≤I-600°C kunye noxinzelelo olufanelekileyo pn≤I-6.4MPA, kwaye isetyenziselwa i-globe valve, i-valve yebhola, njl.

I-9. Ukulima intsimbi

Inqanaba eliqhelekileyo elisetyenziswa ngentsimbi yentsimbi ngo-38Craela, olunokuxhathisa ngokuchasayo kunye nokungaxhathisi okukrakra emva kokucamagushela. Ihlala isetyenziswa kwi-valve yesango lesikhululo samandla kunye neqondo lobushushu t≤I-540℃kunye noxinzelelo olufanelekileyo pn≤I-10PA.

10. Ukukhupha

Ukukhuthaza ngokuthe ngqo inkqubo yokutywina kwi-veli ye-valve okanye umzimba we-div, emva koko wenze ukuqhubela phambili unyango. Umhlaba wokutywina unesiphethi esihle sokunyangwa. Ngesikhululo samandla esivuthiweyo.

Xa iveni isetyenziswa, imicimbi efanele ithathelwe ingqalelo yile ilandelayo:

I-1. Ukusebenza kwetywina kweveli kufuneka kuvavanywe ukuqinisekisa ukusebenza kwalo.

2. Jonga ukuba umphezulu wokutywina kwevalve unxibe, kwaye ulungise okanye ukuba uyibuyisele ngokwemeko.
