Ivalvu yokukhupha umoya wekhwalithi ephezulu

Ihlathululo:

Ivalvu yokukhipha umoya ngejubane elikhulu ehlanganisiweko ihlanganiswe neengcenye ezimbili zevalvu yomoya ye-diaphragm enomfutho omkhulu kanye nevalvu yokungena nokukhipha umfutho ophansi, Inemisebenzi yokukhipha nokungenisa.
Ivalvu yokukhupha umoya we-diaphragm enegandelelo eliphezulu ikhipha ngokuzenzakalelayo umoya omncani obuthelelwe ngaphakathi kwephayiphi lokha iphayiphi nayiphasi kwengcindezi.
Ivalvu yokuthatha nokukhipha umoya onomfutho ophasi ayikwazi ukukhipha umoya ngaphakathi kwepayipi kwaphela lokha iphayiphu enganalitho nayizaliswe ngamanzi, kodwana nalokha iphayiphu nayithululwa namkha nakunomfutho omumbi, njengaphasi kobujamo bokuhlukaniswa kwekholomu yamanzi, izokuvuleka ngokuzenzakalelako bese ingene epayipini ukuqeda umfutho omumbi.

Iimfuneko zokusebenza:

I-valve yokukhipha umoya onomfutho ophasi (umhlobo othambileko + othambileko) i-ekzosi ekulu iqinisekisa bona umoya ungena begodu uphume ngezinga eliphezulu lokugeleza komoya okukhishwa ngebelo elikhulu, ngitjho nokugeleza komoya okukhulu okuhlanganiswe nenkungu yamanzi, angeze yavala i-port ye-ekzosi kusengaphambili.
Nanyana kunini, inqobo nje nangabe umfutho wangaphakathi wesistimu ungaphasi komfutho womkhathi, ngokwesibonelo, lokha nakwenzeka ukuhlukaniswa kwekholomu yamanzi, ivalvu yomoya izokuvuleka khonokho umoya ungene erherhweni ukukhandela ukukhiqizwa kwe-vacuum erherhweni. Ngesikhathi esifanako, ukuthatha umoya ngesikhathi lokha irherho nalithulula kungarhabisa ibelo lokuthulula. Ingaphezulu levalvu yokukhipha ifakwe ipuleti elwisana nokucasula ukwenza bona ikambiso yokukhipha ibe bushelelezi, okungakhandela ukutjhuguluka komfutho nofana ezinye izinto ezibhubhisako.
Ivalvu yokukhipha umoya onomfutho ophezulu ingakhupha umoya obuthelele eendaweni eziphezulu erherhweni ngesikhathi lapho irherho lingaphansi kwengcindezi ukugwema izehlakalo ezilandelako ezingabangela umonakalo erherhweni: ukuvala komoya nofana ukuvaleka komoya.
Ukwandisa ukulahlekelwa yihloko kwesistimu kwehlisa izinga lokugeleza begodu ngitjho nasezimweni ezimbi khulu kungaholela ekuphazamisekeni okupheleleko kokulethwa kwe-fluid. Khulisa umonakalo we-cavitation, ukurhabisa ukugqwala kweengcenye zensimbi, ukwandisa ukutjhuguluka komfutho erherhweni, ukwandisa amaphutha wemitjhini yokulinganisa, nokuqhuma kwegesi. Thuthukisa ukusebenza kuhle kokuphakelwa kwamanzi ekusebenzeni kwamapayipi.

Umthethomgomo wokusebenza:

Ikambiso yokusebenza kwevalvu yomoya ehlanganisiweko lokha ipayipi enganalitho nayizaliswa ngamanzi:
1. Dlulisa umoya ngaphakathi kwepayipi ukwenza bona ukugcwaliswa kwamanzi kuragele phambili kuhle.
.
3. Umoya okhutjhwe emanzini ngesikhathi senqubo yokulethwa kwamanzi uzakubuthelelwa endaweni ephezulu yesistimu, okutjho bona, ku-valve yomoya ukuthatha indawo yamanzi wekuthomeni emzimbeni we-valve.
.
5. Ngemva kokuthi umoya ukhutjhwe, amanzi angena ngaphakathi kwevalvu yokukhipha ummoya ene-pressure ephezulu godu, iphapha ibholo elintantako, bese ivala indawo yokukhipha ummoya.
Lokha ihlelo nalisebenzako, amagadango angenhla ama-3, 4, 5 azokuragela phambili nokujikeleza
Ikambiso yokusebenza kwevalvu yomoya ehlanganisiweko lokha umfutho ohlelweni uphasi nomfutho womkhathi (okukhiqiza umfutho ongasimuhle):
1. Ibholo elintantako yevalvu yokuthatha nokukhipha umfutho ophasi izokwehla khonokho ukuvula iimbobo zokuthatha nokukhipha.
2. Umoya ungena erherhweni ukusuka lapha ukuqeda umfutho omumbi begodu uvikele irherho.
