Yini okufanele siyicabangele ukukhetha i-valve yebhola ye-PVC

Umhlahlandlela wokukhetha i-valve yebhola lepulasitiki

Kukhona i-UPVC, i-CPVC, i-PPH, i-PVDF, i-FRPP impahla ye-plastic ball valves enkampanini yethu oyikhethayo.

Ama-valve e-Plastic Ball asebenza kahle ekushiseni okuphansi, ukucindezela okuphezulu kanye noketshezi oluphezulu lwe-viscosity. Bangakwazi ukuphatha imidiya ngezinhlayiya eziqinile ezimisiwe, kanye nezinto eziyimpuphu ne-granular ezisekelwe ezintweni zokuvala.

Ivalvu yebhola egcwele isiteshi ayakhelwe ukulawula ukugeleza, kodwa ilungele ukuvulwa nokuvala ngokushesha ukuze kube lula ukuvala kuvalwe izimo eziphuthumayo. Ama-valve amabhola asetshenziswa kangcono kumapayipi adinga ukuvalwa okuqinile, imigudu emincane, ukuvulwa nokuvala ngokushesha, umehluko wengcindezi ephezulu, umsindo ophansi, i-gasification, i-torque encane, nokumelana noketshezi okuncane.

Amavalvu ePlastiki Amabhola alungele izinhlelo zokusebenza ezidinga ukwakhiwa okungasindi, ukuvala ingcindezi ephansi nokuphathwa kwendawo edlayo. Futhi zisebenza kahle kakhulu ekuphatheni imidiya ye-cryogenic kanye nepholile ngokujulile. Kuzinhlelo nemishini ephatha imidiya ye-cryogenic, kunconywa ukusebenzisa ama-valve ebhola e-cryogenic anesembozo se-valve.

Inani elikhulu lamandla liyadingeka ukuze kusetshenziswe i-valve enkulu yebhola yobubanzi. Kumavalvu ebhola anobubanzi obungu-DN≥200mm, kuyanconywa ukuthi usebenzise igiya lezikelemu. Ama-valve ebhola angaguquki afanele ububanzi obukhulu kanye nezicelo zokucindezela okukhulu. Ukwengeza, ama-valve amabhola kumapayipi asetshenziselwa ukuthutha izinto ezinobuthi kakhulu noma ezivuthayo kufanele abe nokwakhiwa okungashi kanye ne-antistatic.

I-valve yebhola engaguquki iyi-valve elawula ukuvuleka nokuvalwa kwe-valve ngokuzungezisa ibhola ngaphakathi kwe-valve. Kukhona imbobo phakathi nendawo futhi ingazungeziswa ngo-90°. Ububanzi bembobo edlulayo bulingana noma buncane kunobubanzi bepayipi. Lapho ibhola lizungeza i-90 °, kokubili i-inlet kanye ne-outlet yepayipi imbozwe yibhola, ivala ngokuphumelelayo i-valve futhi inqamule ukugeleza koketshezi.

Uma i-valve yebhola ye-PVC izungeziswa ngo-90° ukuya emuva, kokubili indawo yokungena nokuphuma kwepayipi kuyavela, okuvumela uketshezi ukuba ludlule kuvalvu. Ama-valve e-PVC Ball angazungeza ngama-engeli ahlukene ukuze alawule ukugeleza koketshezi. Ama-valve amabhola angashintshi avame ukusetshenziswa kumapayipi ajwayelekile athutha uketshezi olunjengamanzi, uwoyela, umusi, njll.

Singakhetha kanjani ama-valve ebhola? Yini okufanele siyicabangele ukukhetha i-valve yebhola ye-PVC?

1, Izinto:

Impahla yezingxenye ze-valve yebhola kumele ihambisane noketshezi, ngokuvamile i-UPVC, i-CPVC, i-PPH, i-PVDF nezinye izinto zepulasitiki. Ngasikhathi sinye, ngokuya ngezidingo zangempela zohlelo, khetha ama-valve ebhola ahlukene wezinga lokucindezela.

I-PVC iyimpahla yepulasitiki evame ukusetshenziswa, futhi amavalvu enziwe nge-PVC abizwa ngokuthi ama-valve e-PVC. Ama-valve e-PVC awagcini nje ngokuzinza kwamakhemikhali, kodwa futhi abe namandla amahle wemishini nokusebenza kokucubungula. Ama-valve e-PVC afanele ukuthuthwa kwamanzi okushisa aphansi kanye nengcindezi ephansi ekwakheni, imboni yamakhemikhali, i-metallurgy, amandla kagesi nezinye izimboni.

Kumele kuqashelwe ukuthi ama-valve e-PVC anokumelana okuphansi kwezinga lokushisa futhi ngokuvamile awafaneleki ezindaweni zokushisa eziphezulu. Ngaphezu kwalokho, lapho usebenzisa ama-valve e-PVC, kufanele kuqashelwe ukugwema ukungqubuzana nokungqubuzana ukuze kugwenywe ukuphuka futhi kuthinte impilo yayo yesevisi.

I-PVDF iyimpahla yepulasitiki esebenza kahle kakhulu, amavalvu enziwe nge-PVDF abizwa ngokuthi amavalvu e-PVDF. I-PVDF inezinga eliphezulu lokumelana nokugqwala, ukumelana nokushisa nokumelana nokuhuzuka, futhi isetshenziswa kabanzi embonini yamakhemikhali, imithi, imishini neminye imikhakha. Amavalvu e-PVDF anenzuzo yokukwazi ukumelana namazinga okushisa aphansi kakhulu nezingcindezi eziphezulu, futhi akwazi ukumelana nokugqwala kwamakhemikhali asezingeni eliphezulu.

Kumele kuqashelwe ukuthi ama-valve e-PVDF abiza kakhulu, ukucubungula kwawo kunzima kakhulu, udinga ukukhetha imishini yokucubungula ekhethekile yokukhiqiza. Ukwengeza, ekusebenziseni ama-valve e-PVDF kufanele agweme umthelela, ukungqubuzana nokungqubuzana okukhulu, ukuze kugwenywe ukulimala kwe-valve.

2, Izilinganiso Zengcindezi Nezinga Lokushisa:

Qinisekisa ukuthi i-valve yebhola inengcindezi efanele kanye nezilinganiso zokushisa zokusingatha izimo ngaphakathi kwesistimu. Kufanele ikwazi ukumelana nezingcindezi eziphezulu zokusebenza namazinga okushisa ngaphandle kokuphazamisa ukusebenza noma ukuphepha.

3, Qeda uxhumano:

Khetha uxhumano olufanele lokugcina lwe-valve yebhola ngokuvumelana nezidingo zohlelo lwamapayipi. Ngokuya ngezidingo ezithile zohlelo, cabangela izici ezifana nokuxhunywa okunentambo, okune-flanged noma okushiselwe.

4, Izidingo zokulawula ukugeleza:

Nquma izidingo zokulawula ukugeleza kwesistimu, njengokuvula/ukuvala isevisi noma ukuphonseka, bese ukhetha i-valve yebhola enezici zokugeleza ezifanele (isb., ibhobo eligcwele, ibhore elincishisiwe) kanye nendlela yokulawula (isb. Ukwenza ngesandla, okuzenzakalelayo) ukuhlangabezana nezidingo zokusebenza.

5, Ukuthobela kanye Nesitifiketi:

Qinisekisa ukuthi i-valve yebhola ekhethiwe ihlangabezana namazinga afanele embonini kanye nezitifiketi ezifana namazinga e-DIN, ANSI, ASTM kanye ne-ISO ukuze kuqinisekiswe ikhwalithi, ukusebenza nokuphepha.

6, Usayizi kanye Nokucushwa Kwembobo:

Cabangela usayizi we-valve yebhola nokucushwa kwembobo ukuze uqinisekise ukuhambisana nosayizi wepayipi kanye nezidingo zokugeleza zohlelo. Usayizi wevalvu nokucushwa kwembobo kufanele kufane nezidingo ezithile zohlelo lokusebenza.

Ngokucabangela ngokucophelela lezi zici, i-valve yebhola ingakhethwa ehambisana kahle nezidingo ezithile zohlelo lokusebenza, inikeze ukulawulwa kokugeleza okuphumelelayo nokuthembekile ngenkathi kuqinisekisa ukuphepha nokusebenza.
