Ingabe zikhona izidingo zokufakwa kokuqondisa kovemvane?

Indlela yokufaka yeuvemvane valves kufanele kunqunywe ngokohlobo lwazo kanye nezimo zokusebenza. Amavalvu ovemvane avale uphawu kabili ngokuvamile awanazo izidingo eziqinile zokuqondisa, kodwa kunezikhombisi-ndlela ezinconyiwe zokufakwa; I-valve yevemvane evalwe ngendlela eyodwa kufanele ifakwe iqonde lapho kukhonjiswa khona umcibisholo, futhi isiqondiso sesiqu se-valve kufanele sigweme ukuya phansi sibheke phezulu ukuze kuqinisekiswe ukusebenza okuphephile nokusebenza kokuvala.

Ama-valve ovemvane ahlukaniswe abe izinhlobo ezimbili: ukuvala uphawu okukabili kanye nokuvala uphawu ngakunye. Okokuqondiswa kabiliizivalo uvemvane, ngokwethiyori ayikho imikhawulo eqinile yokuqondisa ekufakweni, kodwa kunezikhombisi-ndlela ezinconyiwe zokufakwa kubunjiniyela obusebenzayo. Isibonelo, epayipini elivundlile, isiqondiso se-valve singakhethwa ngokulandelana kokuya phezulu, okuvundlile, no-45 ° ukuya phezulu. Le ndlela yokufaka kulula ukuyisebenzisa futhi ingaqinisekisa ukufana kophawu. Kumavalvu ovemvane anobubanzi obukhulu (afana ne-DN500 nangaphezulu), kuyatuswa ukuthi ufake umzimba wevalvu uvundlile kanye ne-actuator ngenhla ukuze ugweme ithonya lesisindo sepuleti le-valve ku-torque. Uma indawo yepayipi iqukethe inzika (njengodaka, isihlabathi, namanzi), kutuswa ukuthi ukugeleza okuphakathi kungene kusukela ohlangothini olungemuva lwepuleti lama-valve ukuze kuncishiswe ukuguga nokwelula ukuphila kwamavalvu.

Ukufakwa kwendlela eyodwa evalwe uphawuizivalo uvemvaneinezidingo ezicacile zokuqondisa. Umzimba we-valve uvamise ukumakwa ngezimpawu zomcibisholo, futhi isiqondiso somcibisholo kufanele sihambisane nesiqondiso sokugeleza kwendawo ephakathi epayipini ngesikhathi sokufakwa, ngaphandle kwalokho kungase kubangele ukwehluleka kophawu noma ukuvuza okumaphakathi.

Womabili ama-valve ovemvane abheke kabili kanye ne-unidirectional unidirectional awavunyelwe ukuthi afakwe aqonde phansi aye ngakuso isiqu se-valve. Uma isiqu se-valve sibheke phansi, indawo yepayipi ingase ivuze esiqwini se-valve, ikakhulukazi lapho ithutha i-asidi, i-alkaline, imidiya ewushevu, ebeka engcupheni ukuphepha komuntu siqu kwabaqhubi. Ngaphezu kwalokho, ukufaka isiqu se-valve phansi kuzokwandisa ubunzima bokusebenza, okudinga ukuthi opharetha aphakamise ikhanda lakhe ukuze asebenze, okungahambisani nomklamo we-ergonomic.

Isikhundla sokufakwa kwamavalve evemvane kufanele kube lula ukusebenza. Isibambo noma isondo lesandla lamavalvu ovemvane okwenziwa ngesandla ngokuvamile liqhele ngamamitha angu-1.2 ukusuka endaweni yokusebenza, cishe ukuya endaweni yesifuba, okwenza ukuvula nokuvala kungabi namandla. Uma i-valve ifakwe phansi, isondo lesandla noma isibambo kufanele sibheke phezulu futhi singatsheki; Uma ifakwe ezindongeni noma ezintweni zokusebenza, shiya indawo yokuma ukuze abashayeli bagweme ukusebenza besezulwini.
