Ukutywinwa kwangaphakathi kweivalvu yebhabhathane yomgca oqinileyoI-D341X-CL150ixhomekeke ekudibaneni okungenamthungo phakathi kwesihlalo serabha kunyeipleyiti yebhabhathane YD7Z1X-10ZB1, kwaye ivalvu inomsebenzi wokutywina ngeendlela ezimbini. Ukutywinwa kwesiqu sevalvu kuxhomekeke kumphezulu ongqindilili wokutywina wesihlalo serabha kunye neringi yerabha ye-O ukuze kupheliswe unxibelelwano oluthe ngqo phakathi kwesixhobo kunye nesiqu somzimba wevalvu, ukuze kwandiswe ubomi bevalvu ngokusekelwe ekuqinisekiseni ukusebenza kokutywina.
Yonkeivalvu yebhabhathane yotywino oluthambileyoImveliso ephuma kwifektri yethu ivavanyiwe uxinzelelo ukuqinisekisa ukuba ifanelekile ukuphuma kwifektri.
Kwinkqubo yokuthengisa yokwenyani, ukuvuza kwabafanelekileyo kwifektriivalvu yebhabhathane ethambileyo yetywina MD371X3-10QBIimveliso emva kokufakwa kwipayipi ziyenzeka ngamanye amaxesha, kwaye izizathu zokuvuza kunye nendlela yokususa zishwankathelwe ngolu hlobo lulandelayo:
Okokuqala, isitywina sangaphakathi siyavuza.
Izizathu eziphambili:
1. Umbhobho awuzange ucocwe ngaphambi kokuba kufakwe ivalvu yebhabhathane, kwaye emva kokuba kufakwe ivalvu yebhabhathane, ukungcola okuseleyo kumbhobho kwaphela okanye kwavala iringi yokutywina yevalvu yebhabhathane kunye nepleyiti yebhabhathane, nto leyo eyabangela ukuvuza kwetywina.
2. Ngenxa yokuba umphezulu woqhagamshelwano lokutywina wevalvu yebhabhathane ethambileyo uncinci kakhulu, xa igiya le-worm lingalungiswanga endaweni yalo, ipleyiti yebhabhathane kunye nendawo yokuvala ivalvu yebhabhathane azikho endaweni yazo, kwaye kukho ukuphambuka okuncinci. Xa uvavanyo loxinzelelo lwefektri lufanelekile, inani elincinci lokuvuza linokwenzeka xa lifakwe kumbhobho.
3. Emva kokuba ivalvu yebhabhathane ivuza, indawo ayithathi manyathelo afanelekileyo ophando ukuze kuphendulwe kwiimeko ezingxamisekileyo, nto leyo ebangela umonakalo okanye ukuxinana kweendawo zevalvu.
Isisombululo(izisombululo):
1. Umbhobho awucocwanga: ivalvu ivuliwe ngokupheleleyo, umbhobho ucociwe, kwaye ivalvu yebhabhathane ivulwa kwaye ivalwe izihlandlo ezithathu ukuya kwezihlanu ngexesha lenkqubo yokucoca, kwaye ayivalwanga ngokupheleleyo ngeli xesha. Emva kokucoca, ivalvu yebhabhathane ivalwe ngokupheleleyo ukuze kuvavanywe kwaye kulungiswe iingxaki, nto leyo enokususa ingxaki ngokusisiseko.
2. Ukuba ipleyiti yebhabhathane kunye nendawo yokuvala isitywini azikho kwimeko entle: phinda ulungise i-worm gear kwaye ulungise isikrufu esilinganiselweyo seswitshi ye-worm gear ukuze ufumane indawo yokuvala efanelekileyo yevalvu.
3. Ukuba iindawo zonakele: tshintsha iindawo ezingasetyenziswanga okanye uzibuyisele efektri ukuze zilungiswe.
Okwesibini, ukuvuza kobuso beflange okanye uphawu oluphezulu.
Izizathu eziphambili:
1. Ukusilela okanye ukuguga kweringi yesitywina serabha yesitywina esingaphezulu kukhokelela ekuvuthweni kwesitywina esingaphezulu.
2. Uxinzelelo lombhobho ludlula umda woxinzelelo lokutywina ivalvu, nto leyo ebangela ukuvuza kwesitywina esingaphezulu.
3. Xaivalvu yebhabhathaneifakiwe, iziko alilingani, kwaye i-medium ingena kumphezulu woqhagamshelwano phakathi komzimba wevalvu kunye nesihlalo sevalvu, nto leyo ebangela ukuvuza kwicala leflange.
4. I-flange ayikhethwanga okanye ayifakwanga ngokufanelekileyo, nto leyo ebangela ukuvuza komphezulu we-flange.
Isisombululo(izisombululo):
1. Ukusilela okanye ukuguga kweeringi zokutywina zerabha: Iisleeve zevalvu yepolymer zingongezwa ngokongeza okanye ukutshintsha iiringi zokutywina.
2. Uxinzelelo ludlula uxinzelelo oluqhelekileyo lweivalvu yebhabhathane: nciphisa uxinzelelo lombhobho okanye tshintsha uhlobo lwevalvu enokumelana noxinzelelo.
3. Isixhobo singena kumphezulu woqhagamshelwano phakathi komzimba wevalvu kunye nesihlalo sevalvu: lungisa ulungelelwaniso lweembindini wevalvu yebhabhathanekwaye utshixe ibholithi ngokulinganayo.
4. Kucetyiswa ukuba kusetyenziswe i-flange ekhethekileyo ye-butterfly valve ukuze kubanjwe i-soft seal butterfly valve, kwaye akukho gasket yesinyithi ye-flange efunekayo.
