Abavelisi beValve yentsimbi eyi-10 ephezulu ekufuneka uyazi

Iivalvu zentsimbi ezibunjiweyoziivalvu zeshishini eziqhelekileyo, kwaye igama lazo livela kwinkqubo yokubumba yecandelo lazo eliphambili, umzimba wevalvu. Iivalvu zentsimbi ezibunjiweyo zinokwahlulwa zibeIivalvu zeBhola zeNsimbi eziQhelekileyo, Iivalvu zeSango leNsimbi eyenziweyo, Iivalvu zeGlobe zeNtsimbi eziBunjiweyo, Iivalvu zokujonga zentsimbi eyenziweyonjl., kwaye zinokwahlulwa zibeI-ASTM A105ukubumba,A182, F304, F316, F316L,F22, F91, kunye nezinto ze-F92.

Umgaqo wokwenziwa kweevalvu zentsimbi ezixonxiweyo ulula kakhulu. Ngokuyintloko zifudumeza izinto ezikrwada kubushushu obuphezulu, emva koko zigqume, zinqumle, zigaye nezinye iinkqubo zokwenza imizimba yeevalvu kunye nokulungiswa kweevalvu. Xa kuthelekiswa nezinye iivalvu, iivalvu zentsimbi ezixonxiweyo zinokumelana okuphezulu koxinzelelo kwaye zihlala ixesha elide.

Iimpawu zeevalvu zentsimbi ezibunjiweyo zezi zilandelayo:

Ukusebenza kakuhle kokutywina: Umphezulu wokutywina phakathi kwe-valve trim kunye nesihlalo se-valve yentsimbi eyenziweyo ucutshungulwa ngokusila ngokuchanekileyo, okunokufezekisa isiphumo sokutywina esichanekileyo.

Ukumelana kakuhle koxinzelelo: Ekubeni ibhola kunye nesihlalo sevalvu sevalvu yentsimbi eyenziweyo zicutshungulwa ngokufakelwa kobushushu obuphezulu, zinamandla aphezulu kunye nokumelana noxinzelelo kwaye zinokuhlala zizinzile phantsi koxinzelelo oluphezulu.

Ukumelana nolwelo oluphantsi: Umjelo wokuhamba kwevalvu yentsimbi eyenziweyo awuthintelwanga, nto leyo enokunciphisa ukumelana nolwelo kwaye inciphise ukusetyenziswa kwamandla olwelo.

Ubomi benkonzo ende: Izinto ezikwivalvu yentsimbi eqingqiweyo zicutshungulwa ngokuqingqa okushushu kakhulu, kwaye umgangatho wezinto uzinzile, nto leyo enokuqinisekisa ukusebenza kwayo ixesha elide.

Ukugcinwa lula: Ukusebenza kweswitshi yevalvu yentsimbi eyenziwe ngobumba kulula, kwaye ingavulwa kwaye ivalwe ngokukhawuleza, nto leyo elula ukuyilungisa nokulungisa.

Kukho iinkcukacha ezininzi kunye neemodeli zeevalvu zebhola zentsimbi ezibunjiweyo. Ngokubanzi,I-intshi eyi-1/2(DN15) –4 intshiIimodeli ze-(DN100) zisetyenziswa kakhulu, phakathi kwazoIivalvu zentsimbi ezenziwe nge-intshi eyi-1/2kwayeIivalvu zentsimbi ezibunjiweyo ze-intshi ezi-2zezona zisetyenziswa kakhulu. Kwiimeko ezahlukeneyo zokusetyenziswa kunye neemfuno, ungakhetha imodeli efanelekileyo kunye neenkcukacha ngokwemeko yokwenyani.

Ukusetyenziswa nokugcinwa kweevalvu zentsimbi ezibunjiweyo, la manqaku alandelayo kufuneka aqatshelwe ngokubanzi:

Xa ufaka kwaye usebenzisa iivalvu zentsimbi ezibunjiweyo, kuyimfuneko ukuqinisekisa ukuba indawo kunye nokuphakama kwevalvu kuyahlangabezana neemfuno zokusetyenziswa, kwaye uqinisekise ukuba ufakelo luqinile kwaye luthembekile ukuthintela ukuvuza okanye ukonakala.

Xa uvula kwaye uvala iivalvu zentsimbi ezenziwe ngobumba, kuyimfuneko ukusebenza kancinci ukuze kuthintelwe ukusebenza ngokukhawuleza okanye ngamandla kakhulu okunokubangela umonakalo kwiindawo okanye kuchaphazele ubomi bevalvu.

Kwiivalvu zentsimbi ezibunjiweyo ezingasetyenziswa ixesha elide, kuyimfuneko ukujonga rhoqo ukusebenza kwazo kokutywina kunye nemeko yokusetyenziswa kwazo, kunye nokwenza ulondolozo kunye nononophelo ngexesha elifanelekileyo ukuze kugcinwe iimeko zokusebenza ezilungileyo.

Xa uthenga iivalvu zentsimbi ezibunjiweyo, kuyimfuneko ukukhetha iimpawu kunye nabavelisi abaqhelekileyo, kwaye unike ingqalelo ekujongeni uqinisekiso lomgangatho kunye nemiyalelo yokusebenzisa ukuqinisekisa ukuba uthenga iimveliso zeevalvu ezikumgangatho ophezulu.

Ngamafutshane, njengohlobo oluqhelekileyo lwevalvu,iivalvu zentsimbi ezenziwe ngobuchuleZineendlela ezahlukeneyo zokusetyenziswa kunye nexabiso lokusetyenziswa. Ukuqonda imigaqo yayo yokuvelisa, imigangatho, iimpawu, iintlobo, iimodeli, iinkcukacha, kunye namanyathelo okusebenzisa kuya kunceda ekusebenziseni ngcono nasekugcineni iivalvu zentsimbi ezibunjiweyo kwaye zifezekise ukusebenza kwazo okuzinzileyo kwexesha elide kunye nobomi.
