Umehluko Emkhatsini Wevalve Yensimbi Lefoshiwe Nevalve Yensimbi Lephosiwe

I. Inchubo Yekukhicita

Insimbi Lekhohlisiwe Hlola Ivalve Ikhicita I-China:

Yakhiwa ngendlela yekufoja, le steel billet iyashiswa bese kucindzetelwa (njengekushaya ngesando, kukhipha) kuyasetjentiswa kwentela kuyikha, bese kucubungula ngemishini kwentiwa.

Lenchubo yekufoja yenta letinhlavu tensimbi ticwengisiswe futsi sakhiwo sibe sikhulu, ngaphandle kwetici letifana nema pores kanye nekufakwa kwe slag.

Ivalve yensimbi lephosiwe:

Yakhiwa ngendlela yekulahla, insimbi lencibilikile itfululelwa esikhunjini kutsi iphole futsi yakheke, bese iyacubungulwa.

Lenchubo yekulahla ingabanga tinkinga letifana nema pores, imigodzi yekuncipha noma sakhiwo lesingalingani, lesidzinga kwentiwa ncono ngekucubungula lokulandzelako.

II. Timphahla letiphatsekako

Ivalve yensimbi lefakwe:

Emandla lamakhulu: Kufoja kucedza emaphutsa langekhatsi, futsi emandla emshini (kumelana nekucindzeteleka kanye nekumelana nemtselela) ancono kunalawo ekulahlwa.

Kumelana nekucindzeteleka lokuncono: kulungele kucindzeteleka lokusetulu, kushisa lokusetulu noma timo tekusebenta letimbi kakhulu.

Kuvala lokuncono: Lensimbi inekucina lokusetulu futsi akulula kutsi ivute.

Ivalve yensimbi lephosiwe:

Kucina lokuphansi: Lesakhiwo sekulahla singahle sibe netici letincane, kwenta kutsi kube nekudzabuka ngaphansi kwekucindzeteleka lokukhulu.

Tindleko letiphansi: tilungele kukhicita ngebunyenti emavalvu lamise ngendlela leyinkimbinkimbi noma lamakhulu.

III. Isakhiwo & Sisindvo

Ivalve yensimbi lefakwe:

Lesakhiwo silula kakhulu, silingana kakhulu noma sincane ngendlela lesakhiwe ngayo. Sisindvo lesilula (cishe 20% kuya ku 30% silula kunemavalvu ensimbi lephosiwe lenetintfo letifanako).

Baphakeli beValve Yeluvivane Ye-Wafer Yensimbi Lephosiwe eShayina:

Tinhlaka letiyinkimbinkimbi (njengetindlela tekugeleta letimise ngendlela lekhetsekile, imitimba lenemigodzi leminyenti) tingakhicitwa. Sisindvo sikhulu futsi lubondza luvame kuba lukhulu kwentela kwenta kungabi nemandla.

IV. Timo Tekusebenta Letisebentako

Ivalve yensimbi lefakwe:

Tinhlelo letinemfutfo lomkhulu kanye nekushisa lokusetulu: njengetiteshi temandla, timboni te-petrochemical, kanye nemaphayiphi emfutfo lonemfutfo lomkhulu.

Indzawo lephansi yekushisa: njengetinhlelo tagesi yemvelo lesemantini (LNG), insimbi lefojiwe inekucina lokuncono kwekushisa lokuphansi.

Tindzaba letiyingoti: tintfo letinebuthi, letivutsako naletiqhumako (ngenca yekwetsembeka lokusetulu).

I-China Ivalve Hlola I-Swing Yekujikajika:

Timo tekusebenta letivamile letisemkhatsini naletiphansi: njengekuhlantwa kwemanti, emaphayiphi etimboni jikelele, kanye nemphunga lophansi.

Tindzaba letigcobako: Kumelana nekugcoba kungentiwa ncono ngekwengeta tintfo te alloy (njenge valve yensimbi lengagucuki lephosiwe).

Emavalvu lamakhulu lanebubanti: Uma inchubo yekufoja ilinganiselwe, kulahlwa kulungele kakhulu imitimba lemikhulu yemavalvu.

V. Tindleko & Sikhatsi Sekuletsa

Emavalvu ensimbi lakhiwe:Tindleko letisetulu tetintfo letiluhlata, lutjalomali lolubalulekile ekufezeni emadi kanye nemishini. Umjikeleto wekukhicita lotsatsa sikhatsi lesidze, ulungele emacembu lamancane noma tidzingo letisezingeni lelisetulu. Ngalokuvamile emanani eyunithi laphakeme.

Emavalvu ensimbi:Tindleko tesikhunta tiphansi kakhulu, kwenta kutsi tilungele kukhicita ngebunyenti. Umjikeleto wekukhicita mfishane, futsi tindleko tiyancintisana kakhulu.

VI. Emazinga Lavamile Nekumakwa

Ivalve Yekuhlola Yekukhohlakala YaseChina:

Tincazelo: ASTM A105 (insimbi yekhabhoni), A182 (insimbi lengagucuki), njll Lokumaka kuvame kufaka ekhatsi ligama lelitsi “Forged”.

Ivalve yeLisango Lensimbi:

Tincazelo: ASTM A216 (insimbi yekhabhoni), A351 (insimbi lengagucuki), njll Lokumaka kuvame kufaka ekhatsi ligama lelitsi “Cast”.
