Iivalvu ngamahashe okusebenza athuleyo enkqubo yemizi-mveliso emininzi, elawula ukuhamba, uxinzelelo, kunye nokhuseleko kuyo yonke imibhobho kunye nezixhobo. Nangona kunjalo, nangona inkangeleko yazo yomelele, iivalvu ziyakwazi ukuguga kwaye ziwohloke-kaninzi zikhawuleza kunokuba bekulindelwe. Ke, yintoni emisela ukuba ivalve yeshishini inokuhlala ixesha elingakanani kwisicelo sehlabathi lokwenyani?
Makhe sihlolisise izinto ezintlanu eziphambili ezinempembelelo ebalulekileyo kubomi benkonzo yesivalo-kwaye yintoni enokwenziwa ziinjineli nabaqhubi ukuze bandise.
1. Ukuhambelana kwezinto eziphathekayo siSiseko sokuZinza
Esinye sezizathu eziqhelekileyo zokungaphumeleli kwevalve kwangaphambi kwexesha kukungahambelani kwezinto. Xa umzimba wevalve, isihlalo, okanye izitywina zingaxhathisi kumajelo osasazo—inokuba yiasidi, ibrasive, okanye ubushushu obuphezulu—umonakalo uqala ngaphakathi.
Ukukhetha izinto ezifanelekileyo (ezifana nentsimbi engatyiwa, ubhedu, okanye i-alloys ekhethekileyo) ezilungiselelwe indawo ethile yokusebenza kubalulekile. Ukuqonda iimpawu zeekhemikhali kunye neemeko zokusebenza kuqinisekisa ukuba imathiriyeli yevalvu yakho ayiyi konakala, ikhukulise, okanye yonakale ngokuhamba kwexesha.
Ingcebiso: Soloko uvavanya iitshathi zokuhambelana kwemathiriyeli ngexesha lokukhetha ukuqinisekisa ukuqina kwevalvu yexesha elide.
2. Uxinzelelo lokuSebenza kunye noBubushushu obuchaphazela amanqanaba oxinzelelo
Iivalvu ezilungiselelwe umlinganiselo omnye woxinzelelo okanye ubushushu bunokusilela ngokukhawuleza xa zityhalwa ngaphaya kwemida yazo. Uxinzelelo oluphezulu lubangela uxinzelelo lomatshini, ngelixa amaqondo obushushu aphezulu anokuguqula amatywina okanye akhulise amalungu angaphakathi.
Ukwandisa ubomi benkonzo yevalvu, soloko uqinisekisa ukuba iqondo lobushushu bevalve yakho lihambelana nesicelo. Qwalasela imida yokhuseleko kwimisebenzi eneemeko eziguquguqukayo okanye ezihlabayo.
3. Iimpawu zokuhamba kunye nobungakanani beValve Matter ngaphezu kokuba ucinga
Ukulinganisa i-valve engafanelekanga okanye ukhetho lweprofayili ethile yokuhamba (i-laminar, i-turbulent, i-cavitating) inokukhokelela ekugqokeni kwangaphakathi kunye nokungasebenzi kakuhle. Ngokomzekelo, ivalve encinci kakhulu inokusebenza phantsi koxinzelelo oluqhubekayo, ngelixa i-valve enkulu ingenakukwazi ukulawula ukuhamba ngokuchanekileyo.
I-Cavitation kunye nokudanyaza kuyinkxalabo enkulu kwi-high-velocity flows, ebangela ukugoba kunye nokuguguleka kwexesha. Ukukhetha iivalve ezenzelwe iimeko ezinjalo—ezifana neevalvu zeglowubhu zokushukuma—kunokuthintela ukuguga ngokugqithiseleyo.
4. Ukugcinwa rhoqo kunye noMgangatho uchaza uBomi obude
Kwanezona zivalo zomgangatho ophezulu ziya kusilela ngaphambi kwexesha ngaphandle kokuhlolwa okuqhelekileyo, ukuthambisa, nokucoca. Ukwakhiwa kobutyobo, ukuthotywa kwe-gasket, kunye nokunxitywa koomatshini zonke ziinkqubo ezihamba kancinci kancinci ezinokuncitshiswa ngokulungiswa kwangexesha.
Ukuphumeza isicwangciso sogcino lothintelo olubandakanya uvavanyo lwevalvu, ukutshintshwa kwetywina, kunye nokuhlolwa kwe-actuator kuya kubuphucula kakhulu ubomi benkonzo yesivalo.
Ingcebiso: Sebenzisa iisistim zokujonga imeko yevalvu ukulungiselela ugcino oluqikelelweyo ukubamba imiba ngaphambi kokuba inyuke.
5. IiNdlela zoFakelo kunye nokusiNgqongileyo zidla ngokungahoywa
Ufakelo olungalunganga-njengokuqiniswa ngokugqithiseleyo, ukungahambi kakuhle, okanye ukuxhaswa okunganeleyo-kunokubeka uxinzelelo olungalindelekanga kumacandelo e-valve. Ngokufanayo, iindawo ezingaphandle okanye ezonakalisayo zifuna imilinganiselo yokhuseleko efana neengubo okanye izivalo zokugada ekuvezweni.
Ukunyamekela ngexesha lofakelo kunye nokuqwalasela indawo engqongileyo kubalulekile ekufezekiseni amandla apheleleyo evalve yakho.
Yandisa uMsebenzi ngokuKhetha ulwazi
Ukususela ekukhethweni kwezinto ezifanelekileyo ukuya kwiindlela zokulondoloza eziqeqeshekileyo, ukwandisa ubomi benkonzo yevalve kumalunga nokuqonda umjikelo wobomi bonke-ukusuka kuyilo ukuya ekusebenzeni. Ngokunika ingqwalasela kwezi zinto zintlanu zibalulekileyo, abaqhubi bemizi-mveliso banokunciphisa ukusilela okungalindelekanga, ukomeleza ukuthembeka kwenkqubo, kunye neendleko ezisezantsi zokutshintsha.
