Ukubaluleka

Amavalvu adlala indima ebalulekile ezimbonini kusukela kuwoyela negesi kuya kumapayipi amapayipi nezinhlelo zokufudumeza. Lawa madivaysi amancane alawula ukugeleza koketshezi namagesi, aqinisekisa ukusebenza kahle nokuphepha. Kodwa-ke, ama-valve ngezinye izikhathi angaba nzima ukufinyelela noma ukusebenza ngenxa yendawo noma umklamo wawo. Kulokhu, aisandiso se-valvekungene ukudlala. Kulesi sihloko, sizohlola ukubaluleka kwezandiso zama-valve, izinhlobo zazo ezihlukene, kanye nokusetshenziswa kwazo ezimbonini ezahlukene.

Izandiso zamavalvu ziyithuluzi elibalulekile elenza kube lula ukusebenza nokugcina ama-valve ezindaweni okunzima ukufinyelela kuzo. Banweba isibambo se-valve noma indlela yokulawula, ivumele ukuthi isetshenziswe futhi ilawulwe kude. Izandiso zevalvu zivame ukusetshenziswa lapho i-valve igqitshwe ngaphansi komhlaba, ngemuva kwesivimbelo, noma isebenza ngaphansi kwezinga lokushisa eliphezulu, ingcindezi, noma izimo eziyingozi.

Uhlobo

Kunezinhlobo ezahlukene zezandiso zama-valve emakethe namuhla. Olunye uhlobo oludumile isandiso se-valve stem, esivame ukusetshenziswa kuma-valve atholakala emigodini ejulile noma egqitshwe ngaphansi komhlaba. Leziizandisongokuvamile zenziwa ngezinto ezihlala isikhathi eside njengensimbi engagqwali noma ithusi ukuze zimelane nezimo zemvelo ezinzima. Banikeza ukuxhumana okuqinile phakathi kwesiqu se-valve nesibambo sokusebenza esingaphezulu komhlaba ukuze kusebenze nokulawula kalula.

Olunye uhlobo lwesandiso se-valve isandiso sesondo lesandla. Lezi zandiso zisetshenziselwa ukunweba ukufinyelela noma ukuphakama kwesondo lesandla, okuvumela ukusebenza kahle kwama-valve atholakala ezindaweni ezivalekile noma ezindaweni ezikude. Avame ukusetshenziswa ezimbonini ezifana nokuhlanza amanzi, ukukhiqizwa kwamandla kanye nokucubungula kwamakhemikhali, lapho lawa ma-valve angase afakwe ezindaweni ezingafinyeleleki.

Ngaphezu kwezandiso ze-stem kanye nesondo lesandla, kukhona futhi izandiso zama-lever, ezilungele ama-valve adinga ukuhamba ngamabhayisikili njalo noma atholakala ezindaweni eziyingozi. Izandiso ze-Lever zinikeza ingalo ye-lever enwetshiwe ukuze kukhuphuke amandla nokusebenza okushelelayo. Angafakwa ngokushesha futhi asuswe lapho kudingeka, awenze abe yisixazululo esiguquguqukayo sezimboni ezihlukahlukene.

Ukusebenzisa

Izandiso ze-valve zisetshenziswa kabanzi ezimbonini ezahlukahlukene. Isibonelo, emkhakheni kawoyela negesi, izandiso zamavalvu zisetshenziswa kumavalvu atholakala ezindaweni ezikude ezisogwini noma ezingasogwini. Lezi zandiso zenza abaqhubi bakwazi ukulawula ukugeleza koketshezi noma amagesi, kuqinisekiswe ukusebenza okuphephile nokusebenza kahle kwamapayipi noma izindawo zokukhiqiza. Ngokufanayo, embonini yamanzi namanzi angcolile, izandiso zamavalvu zihlomula ama-valve afakwe kuma-vault angaphansi komhlaba, emigodini noma emakamelweni angaphansi kwamanzi, okwenza kube lula ukuwanakekela nokuwalungisa.

Izandiso zama-valve nazo zisetshenziswa kabanzi embonini ye-HVAC (yokushisa, yokufaka umoya omncane kanye ne-air conditioning). Ama-valve esistimu ye-HVAC ngokuvamile atholakala ezindaweni ezincane noma ezingajwayelekile, okwenza ukusebenza kwawo kube inselele. Izandiso zamavalvu zenza le nqubo ibe lula ngokwandisa ukufinyelela kwesibambo se-valve ukuze kulungiswe nokulawula kalula. Futhi zenza ochwepheshe bakwazi ukwenza ukunakekelwa okujwayelekile ngaphandle kokuphazamisa lonke uhlelo.

Isiphetho

Kafushane, izandiso zama-valve ziyithuluzi elibalulekile lezimboni lapho ama-valve okunzima ukufinyelela khona noma ukusebenza. Benza lula ukugcinwa, ukulungiswa kanye nokusebenza kwamavalvu ezindaweni okunzima ukufinyelela kuzo ngokwandisa ukufinyelela kwesibambo se-valve noma indlela yokulawula. Izinhlobo ezahlukene zezandiso ze-valve stem, izandiso ze-handwheel kanye nezandiso ze-lever ziyatholakala ukuze zinikeze izixazululo ezifanele zezimboni ezihlukahlukene kanye nezinhlelo zokusebenza. Kungakhathaliseki ukuthi ku-oyela negesi, ukwelashwa kwamanzi noma i-HVAC, izandiso zama-valve ziqinisekisa ukusebenza kahle nokuphila isikhathi eside kwama-valve abalulekile.

Izandiso zama-valve nazo zisetshenziswa kabanzi embonini ye-HVAC (yokushisa, yokufaka umoya omncane kanye ne-air conditioning).
