Isisekelo Sokukhetha Ivalvu Nemihlahlandlela I

Namuhla, kunama-valve amaningi kakhulu emakethe. Izinhlobo zama-valve ziyinkimbinkimbi ikakhulukazi, futhi isakhiwo kanye nezinto ezibonakalayo nazo zihlukile. Ukukhethwa kwama-valve kubaluleke kakhulu ekusebenzeni kwesikhathi eside kwedivayisi ezimweni zokusebenza. Ukukhetha okungafanele kwamavalvu kanye nokungazi kahle kwabasebenzisi kungumthombo wezingozi nezinsongo zokuphepha. Kodwa-ke, emphakathini wanamuhla, isidingo semikhiqizo yama-valve siyanda kakhulu embonini. Abasebenzisi kufanele babe nokuqonda okwengeziwe kanye nokuqaphela ulwazi lwamavalvu nezinye izici. Ngokuvamile kunezinhlobo ezimbili zezimpawu zamavalvu, izici zesevisi kanye nezici zesakhiwo. Izici zokusetshenziswa: Inquma ukusebenza okuyinhloko kanye nobubanzi bokusetshenziswa kwe-valve, okuyingxenye yezimpawu ze-valve: izinhlobo zama-valve (ama-valve avaliwe, ama-valve alawulayo, ama-valve okuphepha, njll.); izinhlobo zomkhiqizo (ama-valve esango, ama-globe valves, ama-butterfly valves, ama-ball valves, njll.); izingxenye eziyinhloko ze-valve (umzimba we-valve, ikhava, isiqu, i-disc, i-sealing surface) izinto; Imodi yokudlulisa i-valve, njll. Izici zesakhiwo: Inquma izici zesakhiwo sokufakwa kwe-valve, ukugcinwa kanye nezinye izindlela. Kungokwezici zesakhiwo se-valve: ubude nokuphakama okuphelele kwe-valve, ifomu lokuxhuma ngepayipi (uxhumano lwe-flange, uxhumano lwe-threaded, uxhumano lwe-clamp, uxhumano lwentambo yangaphandle, uxhumano lokuphela kwe-welding, njll.); uhlobo lokubekwa uphawu (indandatho, indandatho enentambo, indawo engaphezulu, i-spray welding, umzimba we-valve); Isakhiwo senduku (induku ejikelezayo, induku yokuphakamisa) njalonjalo.
