Sisekelo seValve

A ivalvuyintfo yekulawula umugca wemanti. Umsebenti wayo losisekelo kuhlanganisa noma kunciphisa kuhamba kwendandatho yephayiphi, kushintja indlela yekugeleta kwemkhatsi, kulungisa umfutfo kanye nekugeleta kwemkhatsi, kanye nekuvikela kusebenta lokujwayelekile kwephayiphi kanye nemishini.

一Kuhlukaniswa kwemavalvu

Ngekuya kwekusetjentiswa kanye nemsebenti kungahlukaniswa kube:

1. Shut-off valve: nqaba noma uxhume phayiphi medium. Njengekutsi: ivalvu yelisango, ivalvu yemhlaba, ivalvu yelibhola, ivalvu yeluvivane, ivalvu ye-diaphragm, ivalvu yepulagi.

2. Hlola ivalvu: kuvikela umkhatsi losephayiphini kutsi ungageleti emuva.

3. Valve yekusabalalisa: shintja indlela yekugeleza kwemkhatsi, sabalalisa, hlukanisa noma hlanganisa umkhatsi. Njengemavalvu ekusakata, ticupho temfutfo, kanye nemavalvu ebhola letindlela letintsatfu.

4. Valve yekulawula: hlela umfutfo kanye nekugeleza kwe-medium. Njengevalvu yekunciphisa umfutfo, ivalvu yekulawula, ivalvu ye-throttle.

5. Valve yekuphepha: kuvimbela umfutfo losemkhatsini kuledivayisi kutsi ungadluli linani lelibekiwe, futsi unikete kuvikeleka kwekuphepha kwemfutfo lomkhulu.

二. Imikhawulo lesisekelo yeivalvu

1. Ububanzi lobubitwako bevalve (DN).

2. Umfutfo we-valve (PN).

3. Kucindzeteleka kanye nekushisa kwevalve: Uma kushisa lokusebenta kwevalve kwedlula lokushisa kwekubhekisa kwemfutfo weligama, umfutfo wayo lomkhulu wekusebenta kumele uncishiswe ngendlela lefanele.

4. Kuguculwa kweyunithi yekucindzeteleka kwevalve:

5. Indlela lesebentako yeivalvu:

Emavalvu etimboni asetjentiswa kuphethiloli, embonini yemakhemikhali, etinsimbini, emandla agezi, emandla enuzi kanye naletinye timboni. Tindzaba letidlulako tifaka ekhatsi emagesi (umoya, umfutfo, i-ammonia, igesi yemalahle, igesi yaphethiloli, igesi yemvelo, njll); tintfo letimanti (emanti, i-ammonia lesemantini, oyili, ema-esidi, ema-alkali, njll). Letinye tato tiyabola njengetibhamu temshini, kantsi letinye tikhipha imisebe leminyenti.
