Iivalvu zebhabhathane kunye neevalvu zesango kwiimeko ezahlukeneyo zokusebenza

Iivalvu zesango kunyeiivalvu zebhabhathaneEzi zilungelelanisiweyo zisetyenziswa ukudlala indima yokutshintsha, ukulawula ukuhamba kwamanzi. Kakade ke, kusekho indlela kwinkqubo yokukhetha iivalvu zebhabhathane kunye neevalvu zesango.

Ixabiso elifanayo levalvu yesango liphezulu kunexabiso levalvu yebhabhathane. Kodwa ukususela ekusetyenzisweni kweminyaka elishumi edlulileyo, ukusilela kwevalvu yebhabhathane kuphezulu kunevalvu yesango, ngoko ke kwiimeko ezivumayo, ukusetyenziswa kwevalvu yesango kwandiswa kufanelekile ukuqwalaselwa.

Umahluko phakathi kwevalvu yebhabhathane nokusetyenziswa kwevalvu yesango:

Ngokuhambelana nendima yevalvu yesango kunye nevalvu yebhabhathane kunye nokusetyenziswa kwevalvu, ukumelana nokuhamba kwevalvu yesango kuncinci, ukusebenza kakuhle kokutywinwa, kuba ipleyiti yevalvu yesango kunye nokuhamba kwemidiya yi-engile ethe nkqo, ukuba ivalvu yesango kwiswitshi yevalvu ayikho endaweni yayo, imidiya kwipleyiti yevalvu ikhuhla ukuze ipleyiti yevalvu ingcangcazele, kulula kakhulu ukuyikhanyisa kumonakalo wetywina yevalvu yesango.

Ipleyiti yebhabhathane eqhutywa yi-valve stem, ukuba ijikwe ngama-90°, iya kukwazi ukugqiba ukuvula nokuvala. Tshintsha i-engile yokuphambuka kwepleyiti yebhabhathane, unokulawula ukuhamba kwemidiya.

Ukusetyenziswa kweemeko kunye nemidiya: ivalvu yebhabhathane ifanelekile kwi-furnace, igesi, igesi yendalo, igesi yepetroleum enyibilikisiweyo, igesi yesixeko, umoya oshushu nobandayo, ukunyibilikisa iikhemikhali kunye nokuveliswa kombane kunye nokukhuselwa kokusingqongileyo, ukubonelela ngamanzi kunye nemibhobho yokwakha kunye nezinye iinkqubo zobunjineli zokuthutha iintlobo ngeentlobo zemidiya yolwelo ebolayo, engabolayo kwipayipi, esetyenziselwa ukulawula nokunciphisa ukuhamba kwemidiya.

Ivalvu yesangolilungu lokuvula nokuvala kwesango, ulwalathiso lokuhamba kwesango luthe nkqo kwicala lolwelo, ivalvu yesango ingasetyenziselwa kuphela ukuvula ngokupheleleyo nokuvala ngokupheleleyo, musa ukusebenzisa kwiiparameter zomnyango kwaye zahlukile. Phucula ubuchule bayo, yenza i-engile yomphezulu wokutywina ekucutshungulweni kokuphambuka, eli sango libizwa ngokuba yi-elastic gate.

Xa ivalvu yesango ivaliwe, umphezulu wokutywina unokuxhomekeka kuphela kuxinzelelo oluphakathi ukuze utywine, oko kukuthi, uxhomekeke kuphela kuxinzelelo oluphakathi oluya kuba ngumphezulu wokutywina wesango kwelinye icala lesihlalo ukuqinisekisa ukuba umphezulu wokutywina womphezulu wokutywina, ozitywina ngokwawo. Uninzi lwevalvu yesango lusetyenziselwa ukunyanzelisa ukutywina, oko kukuthi, xa ivalvu ivaliwe, ukuxhomekeka kumandla angaphandle ukunyanzelisa isango kwisihlalo sevalvu ukuqinisekisa ukuba umphezulu wokutywina wokutywina uyaxhomekeke.

Intshukumo: isango levalvu yesango elinesiqu sevalvu sokuhamba okuthe tye, okwaziwa ngokubaivalvu yesango lesiqu esinyukayoI-Gate valve stem nut kwi-gate, ukujikeleza kwe-handwheel kuqhuba ukujikeleza kwe-valve stem, ukuze i-gate lift, le valve ibizwa ngokuba yi-ivalvu yesango le-nrs.
