Ukukhetha iveli yinxalenye ebalulekileyo yoyilo olufanelekileyo kunye nendlela yolondolozo yokufakelwa kunye neenkqubo zesixhobo. Ukuba i-valves echanekileyo ayikhethiwe kwisicelo esithile, iyunithi yomsebenzisi ingavezwa kwi-onrive yenkqubo yegesi engalunganga okanye engaphantsi yegesi, ilixesha elide, kunye nengozi yokhuseleko.
Iivalves zihlala zikhethwe ngexesha loyilo lwenkqubo ekhethekileyo yokulawula irhasi, kwaye kuwo wonke umjikelo wobomi benkqubo, iingcali zihlala zilandelela iindleko ezingcono kunye nezinye izinto ezisebenzisa iindidi ezifanayo zenkqubo esele zikho kwinkqubo.
Ukukhetha i-valves echanekileyo ukusuka ekuqaleni kubaluleke kakhulu ukunceda i-Poyunithi yoMsebenzisi zithintele ukutshintshwa kwangaphambili kwe-veve kamva.
Ungawenza njani ukhetho olufanelekileyo?
Abasebenzi bezobuchwephesha kunye nokuthenga kwiziko lomthengi banokulandela indlela eyisitampu, ethatha ubungakanani be-akhawunti, ubushushu, isicelo, oovimba, uxinzelelo, iziphelo, kunye nokuhanjiswa.
Ukuqwalaselwa ngokupheleleyo kwemeko nganye yokusebenza kunokukhokelela ekukhetheni ivalve efanelekileyo yokusetyenziswa kwinkqubo yegesi ekhethekileyo.
Oku kulandelayo yinkcazo eneenkcukacha malunga nokuba isitampu sifakwe khona kuYilo lweNkqubo eYodwa:
I-01 s-ubungakanani
Ubungakanani bevali bubonisa inqanaba lokuqhuba kwaye kufuneka luhambelane nenqanaba elifunayo okanye elifunekayo lokuhamba kwenkqubo. Ukuhambahamba kwe-Couned (CV) yevalve ivakalisa ubudlelwane phakathi koxinzelelo lwehlathi kwivali kunye nenqanaba lokuhamba elihambelanayo.
Izinto zoyilo lwe-valve ezichaphazela i-CV zibandakanya ubungakanani kunye nejomemeri yendlela yokuhamba; Ubungakanani be-orifice ye-valve buchaphazela ukuntywila. I-orifice, enkulu kakhulu ireyithi yokuhamba. Ii-ofisi ze-ofisi yeendlela ezahlukeneyo zeValve ziyahluka kakhulu; Umzekelo, ivalve yebhola iya kubonelela ngokuchaseneyo nokuhamba, kodwa ivalve enenaliti iya kuthintela okanye inciphise umgangatho wokuhamba. Oku kufanele ukuba kuqwalaselwe kwinkqubo yakho yokhetho.
I-02 T-iqondo lobushushu
Amaqondo obushushu evali aya kunceda ukulawula ubushushu bamajelo osasazo kwinkqubo, kunye namaqondo obushushu asebenzayo osebenzayo kwindawo engqongileyo. Kubalulekile ukuba uqaphele ukuba i-vallve yevaluthi iya kuhlala ihleli okanye itshintshe rhoqo, kwaye ezi meko zinokuchaphazela ukukhetha i-veli okanye irejista enokwenziwa.
Cinga ngokutshintsha kobushushu obunokubangela izinto zokutywina ukuze zikhule kwaye zikho. Ukongeza, iinxalenye zensimbi zinokuphulukana namandla amaqondo aphezulu, ngaloo ndlela kuncitshiswa iireyithi zoxinzelelo, kwaye kuyafuneka ukuqinisekisa ukuba ivalve ivavanywe ngokupheleleyo phantsi kweemeko ezigqithisileyo.
I-03 A-Isicelo
Cinga ngento ekufuneka yenziwe yivali ethile kwinkqubo, kuya kufuneka ukuba iqale okanye iyeke ukuhamba kwemidiya? Lawula amanqanaba okuhamba? Ukulawula indlela yokuhamba? Khusela inkqubo yegesi ekhethekileyo kwi-overprance?
Ukuba nombono ocacileyo wokusetyenziswa kwe-valve kule nkqubo kuya kukukhokela kuhlobo olucacileyo lohlobo lweValve. Thatha ivali yebhola elula ye-BI engumgaqo-nkqubo njengomzekelo, ngelixa i-valves yebhola inokubeka i-veet, i-vilt isetyenziselwe ukuphosa okanye ukulawula ukuhamba, ivalve yakho ye-Inting okanye ivalve yenaliti okanye ivalve yenaliti okanye ivalve yenaliti okanye ivalve yenaliti okanye ivalve yenaliti okanye ivalve yenaliti okanye ivalve yenaliti.
I-04 m - iphakathi
Okanye ukulawula ukuhamba, ivalve ye-valve okanye ivalve yemitha inokuba luhlobo olungcono.
Ingqwalaselo ngononophelo kufuneka inikwe i-fluid iphakathi ngaphakathi kwenkqubo xa izama ukukhetha ivalve efanelekileyo ngokwenza izinto ezifanelekileyo.
Qinisekisa ukuba imithombo yeendaba iyahambelana nezinto ezenza umzimba wevali, isihlalo, kunye ne-squar, kunye nezinto ezithambileyo zerhasi. Ukusilela ukwenza oko kunokukhokelela ekucocekeni, ukutshisa okanye ukuqhekeka, okunokubeka umngcipheko wokhuseleko kunye neengxaki zemveliso kunye neengxaki zokhuseleko kwiCandelo loMsebenzisi.
Njengamaqondo obushushu, indawo apho i-valve isetyenziswe khona kufuneka ithathelwe ingqalelo. Ngaba iyasebenza kwindawo elawulwa yemozulu, umzekelo ngaphakathi kwesityalo okanye kwindawo evaliweyo? Okanye ngaba isetyenziswa ngaphandle, ivezwe kwimiba yemozulu enjengokukhanya kwelanga, imvula, ikhephu kunye nokugcwala kwamaqondo obushushu ngexesha elide? Ii-valvers kunye nezinto zabo ziyafumaneka kuluhlu olubanzi lwezixhobo. Khumbula ukukhetha ivalve efanelekileyo ngokunxulumene nale micimbi ingentla kwendalo kunye nemozulu ukuze kwandise ubomi benkonzo kunye nokusebenza kwevalve.
I-05 p - uxinzelelo
Uxinzelelo lolunye luqwalaselo olubalulekileyo xa ukhetha ivalve.
Zimbini iintlobo zoxinzelelo:
1. Uxinzelelo olusebenzayo: Uxinzelelo oluqhelekileyo lokusebenza kwinkqubo.
2. Uxinzelelo loyilo: Ubungakanani bomgangatho ophezulu wevalve; Ungaze udlule kulo uxinzelelo loyilo lwayo nayiphi na icandelo lenkqubo yegesi ngaphandle kwemeko yovavanyo olawulwayo.
Umda woxinzelelo wenkqubo yegesi ekhethekileyo isekwe kwicandelo layo eliphantsi elingaphantsi-ukuthemba le nto xa ukhetha ivalve. Uxinzelelo kunye neqondo lokushisa lenkqubo ephakathi linefuthe elibonakalayo kwintsebenzo yecandelo. IiValvu ozikhethileyo kufuneka zikwazi ukumelana noxinzelelo kwaye zisebenze ngaphezulu koluhlu lwamaqondo obushushu kunye noxinzelelo xa kufuneka njalo. Yila, ukukhetha izinto ezibonakalayo kunye nokuqinisekiswa ngawo onke amabakala aphezulu kwi-valve yokusebenza. Kukwabalulekile ukukhumbula ukuba uxinzelelo kunye neqondo lobushushu linempembelelo ebonakalayo omnye komnye.
I-06 e-Uqhagamshelo lokuphela
Iivalve ziza neentlobo ezahlukeneyo zonxibelelwano ezahlukeneyo. Ezi zinokuba zezona zinto zibalulekileyo ze-tube, imibhobho yepayi, iflethi yombhobho, i-weld iphela njlnjl. Nangona ingenzi ngokwesiko levali, ukhetho lokuphela lubalulekile kulwakhiwo lwevali kunye nesakhono sokugcina inkqubo etywiniweyo. Ukuqinisekisa ukuba unxibelelwano lokugqibela lulungele uxinzelelo lwenkqubo kunye nobushushu, kwaye bungobukhulu obufanelekileyo kunye nezinto ezibonakalayo, unxibelelwano olufanelekileyo lunokwenza lula ufakelo lwe-leak kunye nokuphepha amanqaku abongezelelweyo.
I-07 D-Ukuhanjiswa
Okokugqibela, eyokuba uyithathele ingqalelo yonke le nto ingentla kwaye ukhethe iValve efanelekileyo yesicelo sakho, njengakweyiphi na enye into, ukuhanjiswa kwexesha kunye nokubonelelwa okuthembekileyo kubalulekile ukugcina inkqubo ekhethekileyo yegesi ebaleka kwaye isebenze ngokufanelekileyo. Njengenyathelo lokugqibela kule ndlela isitampu, kukho isidingo sokuthatha amandla omthengisi, amandla abo okufezekisa ibango xa ufuna ukusebenza nawe ukuba uqonde iimfuno zenkqubo yakho.
Oku kungasentla yindlela ye-stampde equlunqwe nguWhekly (Afklok), siyakholelwa ukuba ngala manyathelo angasentla, iyunithi yomsebenzisi iya kuba nokuqonda okungcono kwendlela yokukhetha ivalve efanelekileyo. Ukuba unayo nayiphi na imibuzo, uWofy (Afklok) Wamkelekile kakhulu kwimibuzo yakho.
I-Wfyy (Afklok) kwicandelo lezicelo zegesi ezikhethekileyo zeminyaka elishumi elinesithathu, ishishini lesicelo legesi liqhelene kakhulu, kwaye sizimisele ukubonelela ngowona mgangatho wokubonelela, i-SIRTE YENKCAZO YOKUGQIBELA YOKUGQIBELA I-STINATE YENKONZO YABASEBENZI.
