Iivalvu zentsimbi engagqwali zilungele kakhulu ukusetyenziswa kwiipayipi ezibolayo kunye neepayipi zomphunga. Zineempawu zokuxhathisa ukugqwala, ukumelana nobushushu obuphezulu kunye nokuxhathisa uxinzelelo oluphezulu. Zisetyenziswa ngokubanzi kwiipayipi ezibolayo kwizityalo zeekhemikhali, kunye neepayipi zamanzi empompini okanye kwizityalo zokutya. Iivalvu zentsimbi yekhabhoni azinakumelana nokugqwala kwaye zingasetyenziswa kuphela kwiipayipi eziphakathi ezingagqwaliyo ezifana nomphunga, ioyile, amanzi, njl. Ixabiso leevalvu zentsimbi yekhabhoni liphantsi kakhulu kunelentsimbi engagqwaliyo, ngoko ke ngokubanzi akukho mphunga ubolayo kunye neminye imibhobho esetyenziswayo. Intsimbi yekhabhoni iyasetyenziswa, kwaye iivalvu zentsimbi engagqwali kunye nezinye izinto zisetyenziselwa ukugqwala. Oku kulandelayo yinkcazo emfutshane yokukhethwa kwesicelo sevalvu yesango lentsimbi engagqwaliyo kunye ne-valvu yesango lentsimbi yekhabhoni yiValve yeNSW:
1 Yintoni unobangela wokuvuza kwevalvu yentsimbi yekhabhoni
Ivalvu yesango lentsimbi yekhabhoni yivalvu yemizi-mveliso, esetyenziswa kakhulu kwi-petroleum, iikhemikhali, izitishi zamandla kunye neminye imimandla. Inezibonelelo zokwenza izinto ngokuzenzekelayo, kulula ukuyisebenzisa, kunye nobomi benkonzo ende, kodwa xa isetyenziswa
Ngexesha lenkqubo, ngenxa yempembelelo yayo okanye izinto zangaphandle, ivalvu yesango lentsimbi yekhabhoni iya kuvuza. Ngoko ke, yintoni isizathu sokuvuza kwevalvu yesango lentsimbi yekhabhoni? Amanqaku aphambili ngala alandelayo.
izizathu eziqhelekileyo.
1. Ukuchaneka okuphantsi kokucubungula kweringi yokutywina emile okwe-wedge kukhokelela ekuvuzeni kwangaphakathi kwevalufa yesango lentsimbi yekhabhoni. Logama nje ivalufa yesango yophawu olukhulu ikhethiwe, umgangatho weendawo ezingasetyenziswayo uhlala ungcono, ukuze ukuchaneka kokucubungula kweringi yokutywina kungabi phantsi.
1. Iimeko zokusebenza ezingazinzanga kunye nemveliso zikhokelela ekuvuthweni kwangaphakathi kwevalvu yesango. Ivalvu yesango ineemfuno eziphezulu kwindawo yokusebenza. Ukuba imeko yoxinzelelo kunye nobushushu ayizinzanga kwaye uluhlu lotshintsho lukhulu kakhulu, uxinzelelo lwempembelelo kwiringi yokutywina luya kuba lukhulu, nto leyo elula kakhulu. Ukuguquka kwenzeka, okukhokelela ekugqibeleni ekuvuthweni kwevalvu.
3. Umgangatho ophantsi wokugcinwa kwevalvu ukhokelela ekuvuzeni kwangaphakathi kwevalvu yesango. Abanye abasebenzi abayicoci indawo yokutywina yeringi yokutywina xa belungisa ivalvu. Ukubakho kokungcola kuya kuchaphazela ukusebenza kwevalvu. Ekuhambeni kwexesha, indawo yokutywina iya kukrweleka, nto leyo eya kukhokelela ekuvuzeni kwevalvu.
4. Isangqa sokutywina esimile njengomhlwa sekhaka sibangela ukuba ivalvu yesango ivuza ixesha elide. Phantsi kwempembelelo yesixhobo, isangqa sokutywina siyabola lula. Ukuba umhlwa ufikelela kwinqanaba elithile, isangqa sokutywina siya kuxelwa, ukuze ivalvu ivuze.
5. Umzimba wevalvu unesiphako. Ukuba umzimba wevalvu uneengxaki ezifana neembobo, ukugqunywa kweslag, imingxunya, imingxuma yesanti, njl.njl., ivalvu yesango inokuba nokuvuza kwangaphandle ngexesha lokusetyenziswa.
Ngamafutshane, ukuvuza kwevalvu yesango lentsimbi yekhabhoni yingxaki eqhelekileyo. Ukuba kukho ukuvuza, kuya kubeka emngciphekweni ukhuseleko lwezixhobo kunye nabasebenzi, ngoko ke kuyimfuneko ukufumanisa unobangela kunye nokusombulula ingxaki ngexesha elifanelekileyo.
4 Indlela yokukhetha ivalvu yentsimbi engagqwali ethembekileyo
Ngokungafaniyo nevalvu yebhola eqhelekileyo ye-pneumatic, ivalvu yebhabhathane yombane kunye nezinye izixhobo zevalvu, ukuveliswa kwesango akufuneki kulungise ukuhamba kolwelo olomileyo, kodwa kusebenza njengevuleke ngokupheleleyo kwaye kunqunyulwe ngokupheleleyo kwipayipi.
Kusetyenziswa isango lokutshintsha. Ngoko ke kukho iivalvu ezininzi zesango zentsimbi engagqwaliyo ezithengiswayo, yeyiphi imveliso ethembekileyo ngakumbi? Iimpawu zeevalvu zesango zentsimbi engagqwaliyo
Intsimbi engagqwaliyo yenziwe ngentsimbi engagqwaliyo. Intsimbi engagqwaliyo yomgangatho ophezulu kunye nezinye izinto ezisetyenziswayo ukulungisa umphezulu kunye nokucima kunye nokulungisa izinto zenza intsimbi engagqwali ibe yinxalenye elungileyo yokulwa nokugqwala kunye nomgangatho olungileyo.
Ukukrala, kuhlala ixesha elide. Ke ngoko, ivalvu yesango lentsimbi engagqwaliyo idla ngokusetyenziselwa ukulawula ukuhamba kweekhemikhali, kwaye ukutywina kwayo okuhle kunye nokumelana nokugqwala kwenza kube nzima ukukhukuliseka nokuhlanjwa yi-medium.
Ubushushu obuphezulu kunye noxinzelelo oluphezulu umntu unokuqinisekisa ukusebenza kakuhle kokutywina. Yeyiphi ivalvu yesango yentsimbi engagqwaliyo engcono
Kuthiwa ivalvu yesango lentsimbi engagqwaliyo sisixhobo sevalvu yemizi-mveliso, kodwa eneneni ingqwalasela eninzi. Umzekelo, ukuba ukhetho lwevalvu yesango alulunganga, iingozi ezingalindelekanga zinokwenzeka, ngoko ke musa
Ivalvu yesango lentsimbi engagqwaliyo kufuneka ivavanywe uxinzelelo ngaphambi kokuba iphume kumzi-mveliso. Xa uthenga ivalvu, umthengi kufuneka amisele uluhlu loxinzelelo olufunekayo ukuze ivalvu ilunyamezele kwangaphambili ukuze akhethe imodeli kunye neenkcukacha ezifanelekileyo.
Abavelisi abaqhelekileyo bangqongqo kwaye bachanekile ngakumbi kuvavanyo loxinzelelo, nokuba ngumgangatho wevalvu, ubomi benkonzo, ukusebenza kakuhle kweendleko, okanye ukusebenza kokhuseleko.
Kubaluleke kakhulu ukukhetha umenzi oqhelekileyo nothembekileyo, kwaye iimveliso zabavelisi abaqhelekileyo (i-NSW Valve) zikhuselekile ngakumbi.
Umthengi ngamnye uneemfuno ezahlukeneyo zeevalvu zesango zentsimbi engagqwaliyo eyomileyo. Ngokuphathelele ixabiso, umgangatho kunye nokukhuselwa kophawu, abavelisi abahlukeneyo ngamanye amaxesha banomahluko ocacileyo. Ke ngoko, ukhetho lwabavelisi kufuneka luqwalasele izinto ezahlukeneyo.
