Uninzi lweelokhwe zethu zineentsimbi ezintle kwimikhono

Iivalve zezinto ezikhethekileyo zibhekiselele kwiivalvu ezenziwe ngezinto ezikhethekileyo ukuhlangabezana neempawu zokumelana nobushushu obuphezulu, ukuxhathisa kwe-corrosion, ukumelana nokunxiba, kunye nezinye iimeko zokusebenza. Ngenxa yendima ebalulekileyo edlalwa ngama-valve kwintsimi yoshishino, ukukhethwa kwezinto ze-valve kuchaphazela ngokuthe ngqo ubomi benkonzo kunye nokusebenza okuqhelekileyo kwee-valve. Kukho iintlobo ngeentlobo zeevalvu zesixhobo esikhethekileyo, ezihlelwe ngokwemathiriyeli yomzimba wevalvu:

(1) Iivalvu zemathiriyeli engeyiyo isinyithi njengeevaluvu zeceramic, iivalvu zefiberglass kunye neevalvu zeplastiki.

(2) Iivalvu zensimbi ezifana neevalvu zealloy copper, iivalve zealluminiyam, iivalve zealloy lead, iMonel alloy valves, iivalve zentsimbi ephantsi, kunye neevalve zentsimbi ephezulu.

(3) Iivalvu ezinomzimba wesinyithi ezifana neevalvu ezinomgca welothe, iivalvu zeplastiki ezinemigca, kunye neevalvu ezinomgca we-enamel.

Iivalve ezikhethekileyo eziveliswa yi-BOLON zenziwe ngezinto zetsimbi. Ihlelwa ngokwenjongo kwaye isebenza ngolu hlobo lulandelayo:

(1) Isetyenziselwa ukunqumla okanye ukudibanisa ukuhamba kwemidiya. Kubandakanywa iivalvu zesango, iivalvu zeglowubhu, iivalve zediaphragm, iivalve zebhola, iivalve zeplagi, iivalvu zebhabhathane, iivalve zeplunger, iivalve zeplagi yebhola, iivalve zesixhobo senaliti, njl.

(2) Isetyenziselwa ukulawula izinga lokuhamba, uxinzelelo, njl njl. Kubandakanya iivalve zokulawula, iivalve ze-throttle, iivalve zokunciphisa uxinzelelo, njl.

(3) Isetyenziselwa ukuthintela imidiya ukuba ibuye. Kubandakanya iivalvu zokutshekisha zezakhiwo ezahlukeneyo.

(4)Isetyenziselwa ukwahlula, ukusasaza, okanye ukuxuba imidiya. Kubandakanya iivalve zokusasaza kunye neevalve zokuhambisa zezakhiwo ezahlukeneyo.

Indlela yokukhetha izinto ezifanelekileyo zevalve

Ukukhetha izixhobo zevalve ezifanelekileyo kufuna ukuqwalaselwa kwezinto ezahlukeneyo ezifana nendawo yokusebenza, indawo yokusebenza, ubushushu bokusebenza, kunye noxinzelelo. Ngokubanzi, xa ukhetha izixhobo ezikhethekileyo zevalve, la manqaku alandelayo kufuneka aqatshelwe:

1. Ukukhethwa okusekelwe kwi-medium yokusebenza: Izixhobo ze-valve ezahlukeneyo ziyakwazi ukumelana neendaba ezahlukeneyo, kunye nezinto ezihambelanayo kufuneka zikhethwe ngokweempawu zeendaba.

2. Ukukhethwa ngokusekelwe kwiqondo lokushisa elisebenzayo kunye noxinzelelo: Kuyimfuneko ukukhetha izixhobo ze-valve ngokusekelwe kwizinto ezifana nokushisa okusebenzayo kunye noxinzelelo lokuqinisekisa ukuba i-valve inokusebenza ngokuqhelekileyo.

3. Ukuqwalasela iimeko zoqoqosho: Izixhobo ezikhethekileyo zevalve zinamaxabiso ahlukeneyo, kwaye kuyimfuneko ukuqwalasela ngokubanzi izinto zoqoqosho ukukhetha izinto ezifanelekileyo.

Izilumkiso zokusebenzisa izixhobo ezikhethekileyo zevalvu

1. Xa usebenzisa, kuyimfuneko ukuphepha impembelelo yomthwalo kunye nokungcangcazela, kunye nokuphepha ukungqubana kwendawo yezinto;

2. Iinkqubo zokusebenza ezisemgangathweni kufuneka zilandelwe ngexesha lokugcinwa kunye nokugcinwa ukuze kugwenywe ukusetyenziswa kwezinto ezinobungozi ezifana ne-acids kunye ne-alkali;

3. Ngaphambi kokusebenzisa izixhobo ezikhethekileyo zevalve, uhlolo olubanzi kunye novavanyo lomgangatho luyafuneka ukuze kuqinisekiswe ukuba izixhobo ziyahlangabezana neemfuno;

4. Ngethuba lokusetyenziswa, kuyimfuneko ukujonga rhoqo imeko kunye nokusebenza kwezixhobo ezikhethekileyo ze-valve.

Izixhobo ezikhethekileyo zevalvu zibalulekile ekugcineni ukusebenza kwevalvu eqhelekileyo, kwaye ukukhetha izixhobo ezikhethekileyo zevalvu kubalulekile ekuphuculeni ubomi benkonzo yesivalo kunye nokhuseleko. Xa usebenzisa izinto ezikhethekileyo ze-valve, kuyimfuneko ukunikela ingqalelo ekusebenzeni okukhuselekileyo kunye nokugcinwa okufanelekileyo.
