Indima yeValve Evalva kunye nokukhethwa Kwazi-Njani!

Okokuqala, yeyiphi ivalve yokhuseleko

I-valve yokhuseleko loKhuseleko luhlobo lwevalve esetyenziselwa ukukhusela izixhobo zefriji kunye nokhuseleko lwenkqubo, yeyokwazi lokunceda ngokuzenzekelayo. I-Valve eKhuseleko idla ngokudityaniswa komzimba wevalve, ikhava yeValve, iNtwasahlobo, iSpool kunye nezikhokelo. Ukuvula kunye nokuvala kwamalungu kwindawo evaliweyo, xa uxinzelelo lwenkqubo yokufumana izixhobo lungaphezulu kwenkqubo, ukwenzela ukuthintela umbhobho okanye uxinzelelo oluphakathi lungaphezulu kwexabiso elichaziweyo. Ivalve yokhuseleko kwiNkqubo yokufundisa yokudlala indima yokhuseleko yokhuseleko.

Okwesibini, kutheni ufaka i-valves yokhuseleko

I-valve yokhuseleko ikakhulu isetyenziselwa ukukhusela izixhobo zenkuthazo kunye neenqanawa zoxinzelelo (ezinje ngeetanki zokugcina amanzi, i-theks), njl njl. Oku kulandelayo zizizathu ezininzi zokuba kufuneka zifakwe ivala.

1. Ukuthintela ukugqobhoza izixhobo: Xa uxinzelelo ngaphakathi kwezixhobo zefriji okanye inqanawa yoxinzelelo engaphezulu kwexabiso elisetiweyo, ivalve yokhuseleko iya kuvulwa ngokuzenzekelayo ukukhulula izixhobo okanye ukugqobhoza kwenqanawa.

2. Ukukhusela uKhuseleko lwaBasebenzi: Uxinzelelo olugqithisileyo lunokukhokelela kwizixhobo zokuqhushumba okanye ukuvuza, kubangela ukonzakala kumqhubi. Ukufakwa kweeVlanga eKhuseleko zinokunciphisa uxinzelelo ngexesha lokukhusela ukhuseleko lwabasebenzi.

3. Ukuthintela ukungaphumeleli kwenkqubo: Uxinzelelo olugqithisileyo lunokubangela ukonakala kwinkqubo yokwenziwa, njengokuphuphuma kombhobho, ukufaka umonakalo, njl njl. Ukufakwa kwevalve yokhuseleko kunokuphepha ezi ntsizi kwaye zandise ubomi benkonzo yenkqubo.

4. Phuquza iimfuno zomthetho: Ngokwemigaqo efanelekileyo kunye nemigangatho, ezinye izixhobo zefriji kunye neenqanawa zoxinzelelo kufuneka zifakwe kwiivalvu zokhuseleko ukuqinisekisa ukuthotyelwa kweemfuno zokhuseleko.

Okwesithathu, izinto zokukhetha zeValve zokhuseleko zokuqwalasela

Ekukhetheni kweevalo zokhuseleko, ezi zinto zilandelayo kufuneka ziqwalaselwe:

I-1. Izixhobo zohlobo kunye neemeko zokusebenza: Ngokohlobo oluthile lwezixhobo zefriji kunye neemeko zokusebenza, khetha ivalve efanelekileyo yokhuseleko. Umzekelo, amajelo eendaba ezahlukeneyo, amaqondo obushushu asebenzayo kunye neemfuno zoxinzelelo aya kuchaphazela ukukhetha iivasta zokhuseleko.

2. Iimfuno zokuhamba: ngokweemfuno zokuhamba zenkqubo, khetha ivalve efanelekileyo efanelekileyo. Ireyithi yokuqukuqela iphezulu kunye nenqanaba lokuhamba kwenkqubo kufuneka kuthathelwe ingqalelo ukuqinisekisa ukuba ivalve yokhuseleko inokuhlangabezana neemfuno zenkqubo.

3. Uluhlu loxinzelelo lwevalve yokhuseleko: Ngqengqelo yoxinzelelo lwenkqubo, khetha ivalve efanelekileyo yokhuseleko. Ingcinezelo esetiweyo yevalve yokhuseleko kufuneka iphakame kancinci kunoxinzelelo oluninzi lwenkqubo ukuqinisekisa ukuba lingavulwa ngexesha apho inkqubo yenkqubo ifikelele phambili.

4. Izinto zeValve zokhuseleko kunye nokunganyangeki kwe-corrosion: ngokobume bendawo kunye nokungasebenzi, khetha izinto ezifanelekileyo zokhuseleko. Imidiya eyahlukeneyo inokuba nefuthe elibonakalayo kwivalve yokhuseleko, ke kufuneka ukhethe izixhobo ezinganyangekiyo.

5. Isiqinisekiso seValve eKhuseleko kunye neMigangatho yokuthobela: Khetha ivalve yokhuseleko esinokuthotyelwa kunye nokuthotyelwa kwemigangatho efanelekileyo ukuqinisekisa ukuba umgangatho wayo nomsebenzi wakhe othembekileyo.

6. Ukuqwalaselwa kweminye into: Ngokweemfuno ezithile, qwalasela uhlengahlengiso lweValve eKhuseleko, iindlela zokufaka, ulondolozo kunye neemfuno zokulungisa.
