Ibikoresho byibanze byashyizweho biza vuba hamwe nikirangantego cya valve hamwe nirangi

Valve gushiraho no guhitamo ubwoko bukwiye (ntabwo ari moderi). Indangagaciro nigice cyingenzi cyimirimo yimikorere ya sisitemu yinzobere mugihe utegura igishushanyo cya PI. Ibiri muri aya mabwiriza byita ku bisabwa muri rusange by’umusaruro n’umutekano. Mugihe ukora igishushanyo mbonera hifashishijwe aya mabwiriza, umunyamwuga wa sisitemu agomba guhitamo ashingiye kumiterere yihariye yumushinga, imiterere yubumenyi bwikirere, ubufatanye hagati yinganda, ibisabwa nibikorwa byamazi, ibiranga amazi, ibisabwa byihariye kubakoresha nubukungu, nibindi. . Aya mabwiriza atangiza kandi ibiranga indangagaciro rusange zinganda nibintu bigomba kwitabwaho muguhitamo indangagaciro mugushushanya
1. Ibiteganijwe birakoreshwa muburyo bwa sisitemu yimiti. Umuyoboro wavuzwe ntabwo urimo valve yumutekano, umutego wamazi, icyitegererezo cyikigereranyo hamwe nigitutu kigabanya umuvuduko, ariko ushizemo imigezi igabanya isahani ya orifite, isahani ihumye nibindi bikoresho bifata imiyoboro ifite imikorere isa na valve, hamwe na valve yaciwe nka rusange izina ryibi bice bya valve. Imikorere ya valve yaciwe ikoreshwa muguhagarika amazi cyangwa gutuma amazi ahindura icyerekezo cyogutemba, ukurikije umusaruro (harimo umusaruro usanzwe, gufungura no gufunga hamwe nakazi kadasanzwe), kubungabunga no gukenera umutekano hamwe na Igenamiterere, ariko no gusuzuma gushyira mu gaciro ubukungu.
Valve gushiraho no guhitamo ubwoko bukwiye (ntabwo ari moderi). Indangagaciro nigice cyingenzi cyimirimo yimikorere ya sisitemu yinzobere mugihe utegura igishushanyo cya PI. Ibiri muri aya mabwiriza byita ku bisabwa muri rusange by’umusaruro n’umutekano. Mugihe ukora igishushanyo mbonera hifashishijwe aya mabwiriza, umunyamwuga wa sisitemu agomba guhitamo ashingiye kumiterere yihariye yumushinga, imiterere yubumenyi bwikirere, ubufatanye hagati yinganda, ibisabwa nibikorwa byamazi, ibiranga amazi, ibisabwa byihariye kubakoresha nubukungu, nibindi. .
Aya mabwiriza yuzuye kandi muri rusange atangiza igenamiterere rya valve murutonde rwateganijwe hamwe nibisabwa birambuye byimiti itandukanye. Reba ibice byibanze byuburyo bwa PI igishushanyo.
Aya mabwiriza kandi yerekana ibiranga indangagaciro rusange zinganda nibintu bigomba kwitabwaho muguhitamo indangagaciro mugushushanya.
2. Gushiraho agaciro
Agaciro gashyizwe kumupaka
Ibikoresho bitunganyirizwa hamwe nibikoresho bisanzwe bigomba gucibwa kumupaka wibihingwa (mubisanzwe imbere yumupaka wibihingwa)
Ikiruhuko cya Valve, usibye mubihe bikurikira:
(1) Sisitemu.
(2) umuyoboro usohora iyo chute isohoka byihutirwa iri hanze yumupaka; Niba indangagaciro zigomba gushyirwaho muribi bihe byombi, kashe yo kuyobora nayo irasabwa gufungura (CSO)
(3) umuyoboro wibikoresho utazatera umugozi nimpanuka.
(4) Umuyoboro wibikoresho utabipimye.
FIG. 2.0.1 ya valve yashyizwe kumupaka
Indangagaciro kumupaka zashyizweho muburyo butandukanye nkuko bigaragara ku gishushanyo cya 2.0.1. Aho (1) ikoreshwa mubikoresho rusange
Gabanya; Mugihe habaye impanuka zumutekano nkumuriro cyangwa impanuka zingenzi zibicuruzwa byatewe numugozi wibikoresho, amasahani ahumye agomba kongerwaho muri FIG. 2.0.1 kugirango wirinde kumeneka kwimbere. (3) na (5) muri FIG. 2.0.1 birakwiriye kumurongo wo hejuru cyangwa kumurongo wohanagura nyuma yo kugaburira. Valve A irashobora kandi gukoreshwa mugusukura, gusukura, gutahura ibimeneka, cyangwa metero yikizamini irashobora gushyirwaho hagati yimibiri yombi ikurikiranye. (5) mu gishushanyo cya 2.0.1 birakurikizwa aho impinduka zumuvuduko zishobora kuba nini kandi cheque valve ikora nkuguhagarika ako kanya.
Gushiraho imizi ya valve
Iyo igikoresho gikeneye gutwarwa kubakoresha barenze umwe, kugirango byoroherezwe kubungabunga cyangwa kuzigama ingufu, kurwanya ubukonje, hiyongereyeho ibikoresho bifatanye
Usibye gukata-valve, guca-valve bita umuzi wumuzi ushyirwa kumuyoboro wishami wegereye umuyoboro munini. Bikunze gukoreshwa muri sisitemu yibikoresho bisanzwe (urugero: umwuka, umwuka uhumanye, azote, nibindi). Igenamiterere rimwe rirakenewe mugihe ibikoresho bitunganijwe bikoreshwa kubakoresha benshi (urugero: solvents). Umuyoboro werekanye ku gishushanyo cya 2.0.2 ni umuzi wa valve. Mubisabwa bizigama ingufu za antifreeze, intera iri hagati yumuzi wa valve nu mucungezi igomba kuba nto ishoboka.
Igishushanyo 2.0.2 Igishushanyo mbonera cyo gushiraho imizi ya valve
Imiyoboro yimizi igomba gushyirwaho kumiyoboro yose yishami yimiyoboro isanzwe yibikoresho byimiti kugirango birinde umuntu
Kwangirika kwa Valve bitera ibihingwa cyangwa ibihingwa guhagarika.
Imiyoboro y'amazi hamwe no hejuru, ndetse no ku gihingwa kimwe cyangwa ibikoresho bimwe, iyo umuyoboro w'ishami urenze uburebure runaka, ugomba no kongeramo valve umuzi kugirango ugabanye agace kapfuye, kugabanya gukoresha ingufu, kwirinda gukonja.
Ibikoresho bibiri cyangwa byinshi byifashishwa byamazi bigomba kugenwa hakurikijwe akamaro ko kubyaza umusaruro umuzi wamazi.
Umuzi wumuzi wumuyoboro wibikoresho bisanzwe ushyirwaho numuhanga wumuyoboro mugushushanya imiterere, kandi sisitemu yimikorere ikeneye kugenzura niba ishami rikwiye. Kandi umuzi wa valve ugaragara kubintu rusange PI igishushanyo (igishushanyo mbonera).
Kabiri
Gazi ya peteroli yanduye, yaka, uburozi nigiciro cyinshi nibindi byangirika cyane, nka acide ikomeye, soda ya caustic kandi bifite ibisabwa byihariye (nkumunuko unuka wateje umwanda mwinshi ibidukikije) ikigega giciriritse, n'umurongo hepfo kugeza hepfo ibindi bikoresho, ntaho bitaniye nibindi bikoresho bya valve na valve ebyiri bigomba gushyirwaho murukurikirane (valve ebyiri), Kimwe murimwe kigomba gukubitwa hejuru ya tank. Iyo ubushobozi bwo kubika ububiko bunini cyangwa kure, valve nibyiza kugenzura kure. Kugabanya umubare wa valve, komatanya imiyoboro myinshi kumugaragaro umwe nkuko bigaragara muri FIG. 2.0.3–1 niba ibikorwa byemewe.
Umuyoboro wamazi wibikoresho birimo itangazamakuru ryavuzwe haruguru nabyo bizaba ari valve ebyiri, nkuko bigaragara ku gishushanyo cya 2.0.3-1.

2. Uburyo bwo gushyira akamenyetso
1. Shyira ahagaragara ibirimo
JB / T 106-2004. T 12220-1989. Indangagaciro zifite icyerekezo cyerekezo zigomba gushyirwaho ikimenyetso cyo hagati yimyambi.
2. Uburyo bwo gushyira akamenyetso
GB / T. (casting) bizashyirwaho ikimenyetso kumubiri wa valve. Kuri valve ifite ubunini bwizina buri munsi ya DN50, ibimenyetso bine byavuzwe haruguru bizashyirwa kumurongo wa valve cyangwa icyapa nkuko byagenwe nuwabishizeho. Iyo umuvuduko wizina wikimenyetso cyo gutoranya umubiri wa valve ushyizwe munsi yubunini bwizina, igitutu cyizina ntigishobora gushyirwaho kode "PN".
GB / T.
Niba nta ngingo zidasanzwe ziri muri GB / T 12220-1989, ingingo 7 - 19 mumeza yavuzwe haruguru nibimenyetso byubushake bwo gukoresha kubisabwa. Shyira ikimenyetso kumubiri cyangwa icyapa nkuko bisabwa.
GB / T 12220-1989 iteganya ko niba ingano yintoki ari nini bihagije, intoki zigomba guhabwa umwambi werekana icyerekezo cyo gufunga valve cyangwa inyandiko yongeyeho "kuzimya".
JB / T 106-2004: umubiri wa valve ukoresheje guta cyangwa gupfa uburyo bwo guta, ikirango cyacyo kigomba gutabwa cyangwa gupfa gutabwa kumubiri wa valve icyarimwe. Iyo imiterere yumubiri ipfa uburyo bwo guhimba, ikirango cyayo usibye umubiri icyarimwe bipfa guhimba cyangwa gupfa guta, birashobora kandi gushyirwaho ikimenyetso kumubiri hakoreshejwe uburyo bwo gushushanya. Iyo imiterere yumubiri wa valve itunganijwe muguhimba, umuyoboro wibyuma cyangwa icyuma kizunguruka cyo gusudira, ikirango cyacyo usibye gushiraho uburyo bwo gushushanya, ariko kandi birashobora gukoreshwa mubundi buryo butagira ingaruka kumikorere yumubiri wa valve. .
Shyira akamenyetso hamwe nubunini
LJB / T 106-2004 amabwiriza: gushira akamenyetso kubirimo, bigomba gushyirwaho ikimenyetso kumubiri byoroshye kubona ibice. Ibimenyetso bigomba kwerekanwa uko bishoboka kwose mumyanya yo hagati yumurongo wa perpendicular.
