Isingeniso sesakhiwo se-ball valve

I-ball valve iwuhlobo oluvamile lwe-valve, isakhiwo sayo silula futhi sinamandla, sisetshenziswa kabanzi ezinhlelweni ezahlukahlukene zamapayipi amanzi. Okulandelayo incazelo eningiliziwe yesakhiwo se-ball valve:

Okokuqala, izingxenye eziyinhloko

I-ball valve ikakhulukazi iqukethe izingxenye ezilandelayo:

1. I-Sphere: Njengento yokuvala, i-sphere ivame ukuba yindilinga futhi iyindilinga, futhi kwakhiwa isiteshi phakathi ukulawula ukuvulwa kwepayipi ngokujikeleza i-sphere. Izinto zebhola zihlukahlukene, ezivame ukusetshenziswa njengensimbi engagqwali, ithusi, insimbi ephonswe, njll., ukuze zivumelane nezimo zokusebenza ezahlukene kanye nezidingo zemidiya.

2. Isihlalo: Isihlalo siyindlela yokubeka ibhola, ngokuvamile eyenziwe ngezinto zensimbi, ipulasitiki noma izinto ezinwebekayo. Isihlalo sisika umsele ebusweni obuyindilinga bebhola, bese ibhola lijikeleza nesihlalo ukuze lenze uphawu lokuvimbela ukuvuza kwemidiya.

3. Isiqu sevalvu: Isiqu sevalvu yi-shaft edlula phakathi nendawo yesphere, uhlangothi olulodwa luxhunywe kwisphere, kanti olunye uhlangothi luxhunywe kwindlela yokusebenza. Ngokuzungeza noma ukusunduza kwendlela yokusebenza, isiqu sevalvu siqhuba ibhola ukuze lijikeleze futhi libone ukuvulwa nokuvalwa kwepayipi.

4. Indlela yokusebenza: kufaka phakathi indlela yokusebenza ngesandla kanye nendlela yokusebenza ngokuzenzakalelayo. Indlela yokusebenza ngesandla ivame ukwakhiwa yisibambo, igiya, njll., elawula ukunyakaza kwebhola ngokuzungeza ngesandla noma ngokusunduza; Indlela yokusebenza ngokuzenzakalelayo ingafaka injini kagesi, indlela yokusebenza ngomoya, njll., elawula ukunyakaza kwebhola ngezibonakaliso zikagesi noma zomfutho womoya.

5. Umzimba wevalvu: Umzimba wevalvu uyigobolondo levalvu yebhola, esetshenziselwa ukufaka ibhola, isihlalo nezinye izingxenye, futhi inikeze umzila wokugeleza ophakathi nendawo. Ukwakheka komzimba wevalvu kuvame ukubheka ingcindezi kanye nokushisa kwesikhala kanye nokusebenza kokuvala kwevalvu.

Okwesibili, isimiso sokusebenza

Isimiso sokusebenza sevalvu yebhola silula kakhulu: ivalvu iyavulwa futhi ivalwe ngokujikelezisa ibhola ngama-degree angu-90. Uma ibhola lijikeleziswa lihambisana nobuso bokuvala besihlalo sevalvu, i-medium ingadlula ngaphandle kokuvinjelwa ngesikhala esiphakathi kwebhola nesihlalo sevalvu; Uma ibhola lijikeleziswa liqonde ngqo ebusweni bokuvala besihlalo sevalvu, ukugeleza kwe-medium kuyanqanyulwa. Lo mklamo wenza ivalvu yebhola ibe nokuvulwa nokuvalwa okusheshayo, ukusebenza kahle kokuvala, ukumelana nokuguguleka njalo njalo.

Okwesithathu, ukuhlukaniswa ngezigaba

Ngokwezindinganiso ezahlukene zokuhlukaniswa, ama-ball valve angahlukaniswa ngezinhlobo ezahlukene:

1. Ukuhlukaniswa ngesakhiwo: ivalvu yebhola entantayo kanye nevalvu yebhola egxilile. Ibhola levalvu yebhola entantayo lizohamba ngaphansi kwengcindezi ye-medium ukuze lenze uphawu; Indawo yebhola levalvu yebhola egxilile igxilile, futhi ukuvalwa kufezwa ngokuhambisa isihlalo.

2. Ihlukaniswe ngemodi yokushayela: ivalvu yebhola ephathwa ngesandla, ivalvu yebhola kagesi kanye nevalvu yebhola eqhutshwa ngomoya, njll. Ivalvu yebhola ephathwa ngesandla ngokusebenzisa ukusebenza ngesandla kwesibambo ukulawula ukuvulwa nokuvalwa kwevalvu; Ivalvu yebhola kagesi kanye nevalvu yebhola eqhutshwa umoya ziqhuba ukunyakaza kwevalvu ngogesi kanye nomoya ocindezelwe ngokulandelana.

3. Ngokwesigaba sezinto zokuvala: ivalvu yebhola yokuvala ethambile kanye nevalvu yebhola yokuvala eqinile. Ivalvu yebhola yokuvala ethambile esebenzisa izinto ezithambile zerabha noma i-polytetrafluoroethylene njengezivalo; Amavalvu ebhola yokuvala eqinile asebenzisa izinto zensimbi njengezivalo ukuze azivumelanise nezimo ezinzima njengokushisa okuphezulu kanye nokucindezela okuphezulu.

4. Ngokusebenzisa ukuhlukaniswa okuphakathi: ivalvu yebhola lamanzi, ivalvu yebhola lomusi, ivalvu yebhola legesi kanye nevalvu yebhola le-asidi ne-alkali. Izinhlobo ezahlukene zamavalvu ebhola zifanelekela imidiya ehlukene kanye nezimo zokusebenza ukuqinisekisa ukusebenza okuvamile kanye nokuphila isikhathi eside kwevalvu.

5. Ihlukaniswe ngemodi yokuxhuma: ivalvu yebhola yohlobo lweflange, ivalvu yebhola yohlobo lwesandwich, ivalvu yebhola yohlobo lwentambo kanye nezinye izindlela zokuxhuma ukuze zivumelane nezidingo zokufakwa kwezinhlelo ezahlukene zamapayipi.

Ngamafuphi, ukwakheka kwesakhiwo sevalvu yebhola kunengqondo futhi kunamandla, okungahlangabezana nezidingo zokulawula zezinhlelo ezahlukene zamapayipi oketshezi. Ekukhetheni nasekusebenziseni amavalvu ebhola, kuyadingeka ukukhetha uhlobo olufanele kanye nencazelo ngokuya ngezimo zokusebenza ezithile kanye nezidingo eziphakathi ukuqinisekisa ukusebenza okuvamile kanye nokuphila kwesikhathi eside kwevalvu.
