Ngesikhathi senqubo yokukhiqiza amakhemikhali e-petrochemicals, inani elikhulu lezinto ezibolayo ezifana nama-acid, ama-alkali, usawoti, njll. liyavezwa. Ama-valve alwa nokugqwala angalawula ngempumelelo ukuhamba kwezinto ezibolayo kulezi zindawo, aqinisekise inqubekela phambili ebushelelezi yenqubo yokukhiqiza.

Ama-valve okulwa nokugqwala nawo asetshenziswa kabanzi embonini yamakhemikhali amalahle, ikakhulukazi ukulawula ukugeleza kwemidiya ehlukahlukene yokugqwala nokuqinisekisa ukusebenza okuvamile kwemishini yokukhiqiza.

Embonini yemithi, ama-valve okulwa nokugqwala asetshenziswa ukulawula ukuthuthwa kwemithi ehlukahlukene kanye nemidiya egqwalisayo, okuqinisekisa ikhwalithi yemithi kanye nezidingo zokuhlanzeka kwenqubo yokukhiqiza.

Embonini yokudla neziphuzo, ama-valve okulwa nokugqwala asetshenziswa ukulawula ukuthuthwa kwezinto zokusetshenziswa ezihlukahlukene zoketshezi kanye nemikhiqizo, okuqinisekisa inhlanzeko kanye nekhwalithi yemikhiqizo.

Emkhakheni wokuvikelwa kwemvelo, ama-valve okulwa nokugqwala asetshenziselwa ukwelapha izinhlobo ezahlukene zamanzi amdaka, igesi yokukhipha ugesi, kanye nemfucuza eqinile, okuqinisekisa ukuzinza nokusebenza kahle kwenqubo yokwelapha.

Emishinini yokuhlanza, ama-valve okulwa nokugqwala asetshenziswa ukulawula ukugeleza kwesisombululo sokuhlanza, okuqinisekisa umphumela wokuhlanza nokuqina kwemishini.

Amavalvu ezimboni adlala indima ebalulekile embonini kawoyela negesi, eqinisekisa ukusebenza okuphephile nokusebenza kahle kuyo yonke imikhakha ephezulu, ephakathi, kanye neyaphansi. Lawa mavalvu alawula ukugeleza kukawoyela, igesi, kanye nolunye uketshezi, agcina amazinga okucindezela, futhi ahlinzeke ngokuhlukaniswa kwamapayipi, izindawo zokuhlanza kanye nezindawo zokucubungula.

Ama-valve ayizingxenye ezibalulekile ezinhlelweni zomusi ukulawula ukugeleza, ingcindezi, kanye nokushisa komusi ezisetshenziswa ezimbonini ezahlukahlukene. Aqinisekisa ukuphepha, ukusebenza kahle, kanye nokusebenza kahle kakhulu ezitshalweni zikagesi, ezindaweni zokukhiqiza, kanye nezinhlelo zokushisa.

Amavalvu ensimbi ahlanganisiwe adlala indima ebalulekile ekusakazweni kwamanzi kanye nezinhlelo zokuphathwa kwamanzi angcolile ngenxa yokuqina kwawo, amandla, kanye nokusebenza kahle kwezindleko. Lawa mavalvu avame ukusetshenziswa kumanethiwekhi okuphakelwa kwamanzi kamasipala, izinhlelo zokunisela, izinqubo zamanzi ezimbonini, kanye nezindawo zokuhlanza indle.

Amavalvu okulwa nokugqwala adlala indima ebalulekile ezimbonini lapho amakhemikhali aqinile, usawoti omningi, amazinga okushisa aphezulu, kanye nezindawo ezinolaka kungonakalisa amavalvu ajwayelekile. Lawa mavalvu akhethekile aklanyelwe ukumelana nokugqwala, ukubola, kanye nokugqwala kwamakhemikhali, ukuqinisekisa ukusebenza kwesikhathi eside kanye nokuphepha ezisetshenziswa ezibalulekile.
