Ivalve yebhola yeJIS

Ivalve yethu yebhola ye-JIS yenziwe ngokungqongqo ngokwemigangatho yemizi-mveliso yaseJapan enemilinganiselo ekhethekileyo kunye noxinzelelo. Lukhetho lobuchwephesha kuzo zonke iiprojekthi zemibhobho ekumgangatho we-JIS kunye neeprojekthi zaselwandle, ngelixa iivalvu ze-ANSI/ASME zisebenza kwiinkqubo zoshishino zaseNtshona.

Zonke iivalvu zethu zebhola ezidadayo ezidadayo ziveliswa kumgca opheleleyo kunye neemfuno ezisemgangathweni we-JIS. Ibonisa ukutywinwa okuqinileyo okuthembekileyo kunye nokusebenza okugudileyo, okuguquguqukayo ngaphandle kwentshukumo ebambekayo. Iqinisekisa ukuhamba kolwelo oluzinzileyo, iyenza ibe lukhetho oluqhelekileyo nolufanelekileyo lolwakhiwo lweenqanawa, ubunjineli baselwandle kunye nazo zonke iiprojekthi zemibhobho yemizi-mveliso esemgangathweni ye-JIS.

Sivelisa zonke iivalve zebhola ze-JIS kunye nokuhamba komsebenzi osemgangathweni kwaye sihlolisise ngokupheleleyo iyunithi nganye ngaphambi kokuthunyelwa. Sinikezela nge-OEM kunye ne-ODM ngokwezifiso ukuze zihambelane neemfuno zeprojekthi ezahlukeneyo. Ngomgangatho ongaguqukiyo kunye nomgangatho ongqongqo wokuphunyezwa, iivalvu zethu ze-JIS ziqondwa kakuhle ngabathengi behlabathi.

Iimpawu eziphambili

Umahluko phakathi kwe-JIS kunye ne-ANSI/ASME iiValuvu zeBhola

1. Umgangatho kunye neNkqubo yeYunithi

I-JIS imele iMigangatho yoShishino lwaseJapan. Isebenzisa iiyunithi zemetric, ikakhulu ibhekisa kwi-JIS B2071 kunye ne-JIS B2220. Iiklasi zayo zoxinzelelo ziyi-10K, i-20K, i-30K kunye ne-40K, esetyenziswa ngokubanzi kwiiprojekthi zasekhaya zaseJapan kunye neeprojekthi zaselwandle.

I-ANSI/ASME yinkqubo eqhelekileyo yaseMelika. Isebenza iiyunithi zobukhosi kwaye ilandela ASME B16.5 kunye ASME B16.34. Iiklasi zayo zoxinzelelo ziyiKlasi ye-150, i-300 kunye ne-600, eyaziwayo kwiiprojekthi zemibhobho yaseYurophu naseMelika.Amanqanaba oxinzelelo yiKlasi ye-150, i-300, i-600, esetyenziswa ngokubanzi kwiinkqubo zoshishino zaseMelika naseYurophu.

2. Flange & Dimension Difference

Iivalvu zebhola ze-JIS zineesayizi ezikhethekileyo ze-metric flange, imingxuma yebholiti embalwa kunye nedayamitha emincinci yomngxuma. Isakhiwo sobuso beflange sisodwa. Iiflange ze-ANSI/ASME zisebenzisa imigangatho edityanisiweyo yedimensional yeeprojekthi zemibhobho yaseNtshona jikelele.

3. Ukusebenza kunye nokuGxininisa kuYilo

Iivalvu zethu zebhola ze-JIS zixinene. Zitywina kakuhle kuxinzelelo oluphantsi, zilungele iinqanawa kunye nemibhobho yepetrochemical esemgangathweni ye-JIS.

I-ANSI / ASME inokuthatha uxinzelelo oluphezulu kunye nokusetyenziswa okunzima, okukhulu kwiikhemikhali ezinkulu kunye neoli kunye nemibhobho yegesi.

4. Iimeko zesicelo

Iivalvu zebhola ze-JIS zisetyenziswa ikakhulu kwimigca yemveliso esemgangathweni yaseJapan, iindawo zeenqanawa, izibonelelo zaselwandle kunye neeprojekthi zentsebenziswano zase-Asia-mpuma. Iivalvu ze-ANSI/ASME zilawula iiprojekthi zemibhobho yemizi-mveliso yaseYurophu, yaseMelika neyamazwe ngamazwe.

5. Iqondo lobushushu kunye noHlengahlengiso lweMeko yokuSebenza

Iivalvu zebhola ze-JIS zisebenza kakuhle kwiindawo eziqhelekileyo zobushushu obuphantsi kunye obuphakathi. Bagcina itywina eliqinileyo ngokuzinzileyo kusetyenziso lwaselwandle nakwimizi-mveliso ngokubanzi.

Iivalvu zebhola ze-ANSI/ASME zibamba amaqondo obushushu aphezulu kakhulu kunye neemeko zokusebenza ezinzima. Zilungele ubushushu obuphezulu be-steam kunye nokuthutha ioli enzima.

6. Ufakelo kunye noLondolozo

Iivalvu zebhola ze-JIS zinokwakheka okulula, okuxineneyo. Ziyakhawuleza ukufaneleka kwaye kulula ukuzithatha ukuze zigcinwe. Iinxalenye zikwafikeleleka ukuba zithathe indawo yeeprojekthi ezisemgangathweni we-JIS. Iivalvu ze-ANSI/ASME zinesakhiwo somzimba esityebileyo kunye nezincedisi ezomelele ngakumbi, ezifuna ugcino olusemgangathweni olusemgangathweni, olufaneleke ngakumbi kwiiprojekthi zemizi-mveliso ezithatha indawo ezihlala ixesha elide.
