Indlela yokukhetha kuhle izinto zokuvala

Ngiziphi ezinye izinto eziqakathekileko ekufuze ziqalwe lokha nawukhetha into efaneleko yokuvala isicelo?

Intengo ehle khulu nemibala efaneleko

Ukutholakala kwamatshwayo

Zoke izinto ezinomthelela erherhweni lokuvala: isib. izinga lokutjhisa, uketshezi kanye nomfutho

Zoke lezi zizinto eziqakathekileko okufanele uzicabangele erherhweni lakho lokuvala. Nangabe zoke izinto ziyaziwa, kuzokuba lula ukukhetha izinto ezifaneleko.

Kodwana okutlhogekako kukuthi izinto kufanele zibe zihlala isikhathi eside. Njeke into yokuthoma okufanele uyicabangisise kusebenza kwezobuchwepheshe. Akhesithome ngesici sokusebenza.

Isikhathi sokuphila kwesistimu kanye neendleko zizinto eziqakathekileko (I-TIanjin Tanggu Water-Seal Valve Co.,ltd) ukucabangela. Zoke izinto zizokuthinta ukusebenza kwesicelo sakho. Kuqakathekile ukucabangela izinto zokuklama ngokuya ngokusetjenziswa. Lokhu kufaka hlangana izinto ezisetjenzisiweko, amajamo we-hardware kanye neenkambo zokukhiqiza. Kunezinto eziphathelene nebhoduluko ekufuze ziqalwe ezifaka hlangana: ukugandeleleka, izinga lokutjhisa, isikhathi, ukuhlanganiswa kanye nemidiya.

i-elastomer

Ama-elastomer adumileko ngokuthamba kwawo okuhle. Akukho enye into enezinga elifanako lokuthamba.

Ezinye izinto ezifana nama-polyurethane nama-thermoplastics zijamelana khulu nokugandeleleka ukudlula ama-elastomer.

Iinsetjenziswa zerabha zingasetjenziswa eensetjenzisweni ezihlukahlukeneko.

Izakhiwo eziqakathekileko zomtjhini zifaka hlangana

ukuthamba

ukuqina

amandla wokudonsa

Ezinye izinto eziqakathekileko zifaka hlangana

•Isethi yokucindezela

•ukujamelana nomtjhiso

•ukutjhuguluka kwezinga lokutjhisa eliphasi

•ukukhambelana kwamakhemikhali

•Ukulwa nokuguga

•ukujamelana nokuguga

Isici esiqakatheke khulu kukuthamba kwezinto zerabha. Akhe sifunde kabanzi ngalokhu.

Ukuthamba kungumphumela wokutjhuguluka. Iinsetjenziswa ezine-elastomeric, ezifana nerabha evulkanisiweko, zizokubuyela esimweni sazo sokuqala nangabe zikhubazekile.

Iinsetjenziswa ezinganamandla, ezifana nerabha engakavulwa, angeze zabuyela ebujameni bazo bokuthoma nangabe zikhubazekile. Ukutjhuguluka (okufanaivalvu yevithamini ye-flange ephindwe kabili) yindlela yokutjhugulula irabha ibe yinto ye-elastomeric.

Ukukhethwa kwama-elastomer kusekelwe khulu ki:

•ububanzi bezinga lokutjhisa lokusebenza

•Ukujamelana noketshezi namagesi

•Ukujamelana nobujamo bezulu, i-ozone kanye nemisebe ye-UV

Ukukhethwa kwama-elastomer kusekelwe khulu ki:

•ububanzi bezinga lokutjhisa lokusebenza

•Ukujamelana noketshezi namagesi

•Ukujamelana nobujamo bezulu, i-ozone kanye nemisebe ye-UV

Izinto ezisithandathu ekufuze ziqalwe lokha nakukhethwa izinto zokuvala ivalvu

Indawo yokuvala yindawo eqakatheke khulu yokusebenzaivalvu, ikhwalithi yendawo yokuvala ithinta ngqo impilo yesevisi yeivalvu, begodu izinto zendawo yokuvala ziyinto eqakathekileko ukuqinisekisa ikhwalithi yendawo yokuvala. Ngalokho-ke, izinto ezilandelako kufanele ziqalwe lokha nakukhethwa into yokuvala ivalvu:

①Ukujamelana nokugqwala. "Ukugqwala" yindlela lapho ingaphezulu lendawo yokuvala lilimala ngaphasi kwesenzo se-medium. Nangabe ubuso bendawo yokuvala bugugile, ukusebenza kokuvala angeze kwaqinisekiswa, njeke into yendawo yokuvala kufanele ingavumi ukugqwala. Ukujamelana nokugqwala kwento kuncike khulu ekwakhiweni kwento kanye nokuzinza kwayo kwamakhemikhali.

②Ukulwa nokurhurhuka. "Ukuklwebheka" kutjho umonakalo obangelwa kutjhayisana kwezinto ngesikhathi sokunyakaza okuhlobeneko kwendawo yokuvala. Umhlobo lo womonakalo nakanjani uzokubangela umonakalo ebusweni bokuvala. Ngalokho-ke, into yokuvala indawo kufanele ibe nezakhiwo ezihle zokulwa nokuklwebheka, khulukhulu amavalvu wesango. Ukujamelana nokuklwebheka kwento kuvamise ukunqunywa zizakhiwo zangaphakathi zento.

③Ukujamelana nokuguguleka. "Ukuguguleka" yindlela yokutjhabalalisa indawo yokuvala lokha umtjhini nawugeleza ngebelo elikhulu. Lolu hlobo lomonakalo lubonakala khulu kumavalvu we-throttle kanye namavalvu wokuphepha asetjenziswa emazingeni womtjhiso aphezulu kanye nemitjhini ephezulu, begodu unomthelela omkhulu ekulinyazweni kokusebenza kokuvala. Ngalokho-ke, ukujamelana nokuguguleka kwehlabathi kungenye yeemfuneko eziqakathekileko zokuvala izinto eziphezulu.

④Kufanele ibe nobunzima obuthileko, begodu ubudisi buzokwehla khulu ngaphasi kwezinga lokutjhisa lokusebenza elibekiweko.

⑤I-coefficient yokunwebeka komgqa wendawo yokuvala kanye nezinto zomzimba kufanele zifane, okuqakatheke khulu esakhiweni sendandatho yokuvala, ukwenzela bona kugwenywe ukugandeleleka okukhulu nokukhululeka emazingeni womtjhiso aphezulu.

⑥Nayisetjenziswa ngaphasi kweemeko eziphezulu zokutjhisa, kufanele kube nokulwisana ne-oksijini okwaneleko, ukujamelana nokudinwa kokutjhisa kanye neendaba zomjikelezo wokutjhisa.

Ngaphasi kobujamo bamanje, kubudisi ukuthola into yokuvala ehlangabezana neemfuneko ezingenhla. Singagxila ekuhlangabezaneni neemfuneko zezinto ezithileko ngokuya ngemihlobo ehlukileko yamavalvu nokusetjenziswa. Ukwenza isibonelo, amavalvu asetjenziswa eendaweni ezinejubane elikhulu kufanele atjheje khulu iimfuneko zokujamelana nokuguguleka kwendawo yokuvala; begodu lokha umkhathi unezinto eziqinileko eziqinileko, kufanele kukhethwe izinto zokuvala ezinobunzima obuphezulu.
