Insimbi engagqwali yensimbi threaded

Le valve enokwenziwa yensimbi engenasici inendlela yokuxhuma enezintambo, okungukuthi, imicu yangaphakathi noma yangaphandle emikhawulweni yomibili ye-valve ihlanganiswe ndawonye nepayipi elihambisanayo lepayipi ukuze kufinyelelwe ukufakwa ngepayipi. Le ndlela yokuxhumeka akuyona into okulula ukuyifaka kuphela, ngaphandle kwesidingo samathuluzi okuxhumeka okuyinkimbinkimbi noma amakhulu okuxhumeka, kepha elula kakhulu ukuqaqa ngokulungiswa kwamuva noma ukufakwa esikhundleni kwe-valve, futhi kudinga i-wrench ejwayelekile. Ekunikezelweni kwamanzi ekwakheni kanye nama-drainage, ama-hvac, amapayipi amancane wezimboni, nokudla, isiphuzo, amakhambi kanye nezinye izimboni ezinezidingo eziphakeme ezenziwe nguShengshi Huagong, ukuqinisekiswa kwensimbi engenasici, okuzinzile kohlelo lokuqinisekisa uhlelo lwayo oluphephile.

Izinzuzo Zomkhiqizo

(I) ukumelana okuhle kakhulu kokugqwala

Izinto zensimbi ezingenasici zinikeza ukumelana okuhle kwe-valve ukuqiniseka okuhle, okukuvumela ukuthi kusebenze kungenzeka ukuthi zisebenze ezindaweni ezahlukahlukene zabezindaba ezinokhahlo. Embonini yamakhemikhali kanye ne-acids ehlukahlukene ye-acid kanye ne-alkali zivame ukuthuthwa, njenge-sulfuric acid, i-hydrochloric acid, i-sodium hydroxide nezinye izixazululo. Ama-valves enziwe ngezinto ezijwayelekile alimala kalula ngokugqwala, ngenkathi ama-valves angenazinsimbi ahlolwe ngempumelelo angamelana nempumelelo yale mithombo ye-valve yensimbi ephezulu kanye nama-valve ama-valves aphezulu futhi anciphise ukufakwa kwezindleko nezindleko zokugcina ezibangelwa ukugqwala. Embonini yokudla kanye nophuzo, yize ukulungiswa kwe-medium uqobo kuyabuthakathaka, izidingo zokuhlanzeka ziphezulu kakhulu. I-valve yensimbi engenasici ayikwazi ukuvikela kuphela i-backflow ye-lindow, kepha ukwaziswa kwensimbi okungenakuqhathaniswa okungenakuqhathaniswa nakho kungaqinisekiswa ukuthi ukudla neziphuzo ukuthuthwa ngeke kungcoliswe izindinganiso ezibonakalayo ngesikhathi sokuhlanzeka nokuphepha.

(Ii) isakhiwo esilula futhi esilula sokufaka

Indlela yokuxhumeka yentambo yenza ukwakheka kokufakwa kwe-valve yensimbi engagqwali ye-valve compact kakhulu. Uma kuqhathaniswa nama-valve axhumekile e-Flange-axhumekile, ayidingi ama-flanges amakhulu nama-bolts amade wokuxhuma, anciphise kakhulu ubude be-valve. Ezindaweni ezinezikhala ezincanyana ezinjengezakhiwo zepayipi, izinzuzo zalo ezihlelekile zisobala. Ingafakwa kalula esikhaleni esilinganiselwe, kunciphisa umthelela kumapayipi azungezile kanye nesakhiwo semishini. Ngaphezu kwalokho, inqubo yokufaka yokuxhumeka okufakiwe ilula futhi ingasebenza nge-wrench ejwayelekile. Ayikho imishini yokufaka i-welding noma amathuluzi amakhulu okufaka adingekayo, anciphisa ubunzima kanye nezindleko zokufakwa. Lapho i-valve igcinwa noma ifakwe esikhundleni esiteji esizayo, ingasuswa ngokushesha futhi kalula isuswe epayipini, elithuthukisa ukusebenza kahle kokulungisa kanye nokunciphisa umthelela wokulungiswa kwemishini ekukhiqizeni noma ekuphileni.

(Iii) Ukusebenza kokubekwa uphawu okuthembekile

Ukulungiswa okuphezulu okuphezulu phakathi kwe-valve disc kanye nesihlalo se-valve kanye nezindlela zokubopha ezisizayo, ezinjengemishini yokuvala uphawu kwenjoloba, nikeza ukusebenza okuthembekile kokubekwa uphawu kwensimbi engenalutho. Lapho i-valve ivaliwe, i-valve disc icindezelwe ngokuqinile esihlalweni se-valve ngaphansi kwemiphumela emibili yengcindezi yokubuyela emuva yamandla aphakathi nendawo namandla ayo adonsela phansi, yakha indawo enokwethenjelwa ukubekezelela ukuvikela ngokuphumelelayo kokuvuza okuphakathi nendawo. Noma ngaphansi kwezimo zokusebenza kokushintshashintsha kwengcindezi enkulu ohlelweni lwepayipi, isakhiwo sokubopha phakathi kwe-valve disc nesihlalo se-valve singashintsha ngokuzenzakalelayo ingcindezi yokubopha futhi ngaso sonke isikhathi qhubeka nomphumela omuhle wokubopha uphawu. Isibonelo, kwezinye izinqubo zokukhiqiza ezimbonini, ingcindezi ephakathi kwipayipi ingashintshashintsha njalo ngenxa yezinguquko kwinqubo yokukhiqiza. I-valve yensimbi engagqwali i-valve ingalondoloza ngokusheshe i-wap, ivikele ukuphepha okuphakathi, ukuqina kwenqubo yokukhiqiza, nokugwema ukungcoliswa kwemvelo kanye nezingozi zokukhiqiza ezibangelwa ukuvuza okuphakathi.

(Iv) ukusebenza okusebenzayo kokuhlola

I-valve disc design ye-valve yensimbi engenasici ilungiswe kahle futhi impendulo yesenzo iyashesha. Lapho ukuqondiswa kokugeleza kwezinguquko eziphakathi, i-valve disc ingavalwa ngesikhathi esifushane kakhulu, ukusika ngokuphumelelayo isiteshi se-liment Reflux futhi ivikele inani elikhulu le-medium emuva emuva. Ijubane layo lokuvala ngokushesha linganciphisa kakhulu ubungozi bomonakalo kwimishini ohlelweni lwepayipi olubangelwa ukubuyela emuva okuphakathi. Kweminye imigqa yokukhiqiza yezimboni enezidingo eziphakeme kakhulu zokuqhubeka koketshezi okuqhubekayo, njengezimboni zamakhemikhali nezemithi, lapho umgwaqo ugelezela emuva, kungadala imiphumela yenqubo yokukhiqiza nokwehla kwekhwalithi yomkhiqizo. Ukusebenza okusebenzayo kokuhlola kwe-valve yensimbi engenasici kungaqinisekisa ukuthi inqubo yokukhiqiza ayiphazanyiswa yi-backflow ephakathi, iqinisekise ukuqhubeka nokukhiqizwa, ukuthuthukisa ukukhiqiza, futhi kuveze amandla amahle ezomnotho ebhizinisini.
