Ukuhlelwa kweeValve ezinkulu zeBhola: Isikhokelo esibanzi

Xa kufikwa kwiinkqubo zokulawula amanzi,I-valves yebholaziphakathi kwezona zinto zinokuthenjwa neziguquguqukayo. Amandla abo okusingatha uxinzelelo oluphezulu kunye nosetyenziso lwamaqondo obushushu obenza ukuba babe nakho kumashishini. Eli nqaku libonisaUkuhlelwa kweeValves ezinkulu zeBig, iintlobo zazo, kunye nokuqwalaselwa okuphambili xa kufunwa ukusuka kwithemba elithembekileyoUmenzi weValve PalveokanyeUmboneleli eTshayina.

Yintoni ivali yebhola

A ivalve yebholayi-valve yekota esebenzisa umngxunya, onesifo, kunye nebhola epivo yokulawula ukuhamba kwamanzi. Xa ivalve ivulekile, umngxunya webhola uhambelana nombhobho, uvumela ulwelo ukuba ludlule. Xa ivaliwe, ibhola ijikeleza i-90 degrees ukuba ithintele ukuhamba. Uyilo lwayo olulula luqinisekisa ukuqina, ukuvuza okuncinci, kunye nokusebenza kwemali.

Ubungakanani beebhotile ezinkulu zeBhola, ngokwesiqhelo zichazwa njengezona zine-intshi ezingama-40 i-intshi (DN1000) okanye enkulu, zibanzi, ziyinjini yezicelo ze-oyile kunye negesi, ukuqhubela kwamachiza, kunye nemveliso yamandla, kunye nemveliso yamanzi, kunye nemveliso yamandla, kunye nombane.

I-valve yebhola: izinto eziphambili

Ukuqonda i-anatomy yeivalve yebholaKubalulekile ukukhetha uhlobo olufanelekileyo lweemfuno zakho:

1. Umzimba: Zihlala izinto zangaphakathi; Izinto eziqhelekileyo ziqokelela intsimbi engenasibala, i-iron yentsimbi, kunye nentsimbi yekhabhoni.
2. IbholaInqanaba elijikelezayo elinomkhonto olawula ukuhamba.
3. Izihlalo: Yenza itywina phakathi kwebhola nomzimba.
4. Isiqu: Inxibelelanisa i-acturator kwibhola yokujikeleza.
5. Isenzo semali: I-Lever Lever, igiya, okanye inkqubo ezenzekelayo (umbane / pneumatic).

KubaUbungakanani beBhola yeBhola enkulu, ukwakhiwa kombane kunye nokuqiniswa kokutywina kubalulekile ukumelana neengcinezelo ezigqithisileyo kunye namaxabiso okuhamba.

Iindidi zeValve zebhola: Ukwahlulahlulwa ngokusekwe kuyilo

I-valves ivisi ihlelwa kwiindidi ezininzi ngokusekwe kuyilo lwabo kunye nokusebenza kwayo:

I-valve yebhola yebhola

-Ibhola inqunyanyisiwe zizitulo, ezifanelekileyo ukuba ubukhulu bubekho.
-Iindleko ezisebenzayo kodwa zilungele iUbungakanani beBhola yeBhola enkulungenxa yeemfuno eziphezulu zetota.

I-Trinanion inyuka i-valve yebhola

-Ibhola ikhutshiwe yi-trunnion (i-pivot), ukunciphisa i-torque esebenzayo.
-Khetha iUbungakanani beBhola yeBhola enkulukwii-oyile eziphezulu zeoyile kunye negesi.

I-bore egcweleyo

- Iphelile: I-Diamere yebhola ihambelana nomgaqo, ukunciphisa uxinzelelo.
- IncitshisiweIbhola encinci encinci, ilungele iinkqubo ezixineneyo.

I-Potli-Port Polve yeBhola yePort

- Yenza amazibuko amaninzi okutshintsha, asetyenziswe kwiinkqubo zokuhambisa ezintsonkothileyo.

I-calve ye-calisity ezele

-Enzelwe ukuthintela ukungena kwamanzi kwibhola, kubaluleke kakhulu kwizicelo zococeko okanye zoncedo.

Kutheni ukhetha i-valve enkulu yebhola

Ubungakanani beBhola yeBhola enkuluzibalulekile:

- Iinkqubo eziPhezulu zokuhamba: Ukulawulwa ngokufanelekileyo kwemithanga enkulu ye-falls okanye igesi.
- Ukuqina: Yakhiwe ukujongana nemithombo yeendaba yokuphambuka okanye eyongamileyo.
- Ulawulo oluchanekileyo: Qinisekisa ukuvalwa okuthembekileyo kwizicelo ezibalulekileyo.

Ukukhetha umenzi we-valve onokuthenjwa

Xa ukhunjulwaUbungakanani beBhola yeBhola enkulu, ndisebenzisana nenye ephikayoUmzi mveliso we-valve yebholaokanyeUmboneleli eTshayinainika izibonelelo njengokhuphiswanoixabiso, Ukuzaliseka ngokwezifiso, kunye nokubambelela kwiMigangatho yeHlabathi (API, i-ANI, iso). Izinto eziphambili ekufuneka ziqwalaselwe:

1. Umgangatho wezinto ezibonakalayo: Qinisekisa i-valves ye-valves ye-alrosion ye-irrosion.
2. Iziqinisekiso: Jonga i-ISO 9001, API 6D, okanye amanqaku.
3. Ukwenza ngokwezifiso: Khetha abavelisi ababonelela ngezisombululo ezijolise kwiimfuno zomsebenzi ezodwa zokusebenza.
4. Inkxaso yentengiso yasemva kwentengiso: Iwaranti, uncedo lobuchwephesha, kunye nenxalenye yokufumaneka kwendawo.

I-China ihlala ingumhlaba wehlabathiUkwenza i-valve ye-valve, kunye nabathengisi bedibanisa itekhnoloji yokusebenza kunye nokusebenza kweendleko.

Ukuqukumbela

UkusukaI-valve edadayoukuya emsebenzini okukhuluI-Trinanion inkanyezi, ukuqonda ukwahlulahlulaUbungakanani beBhola yeBhola enkuluiqinisekisa ukhetho olufanelekileyo lwezicelo zophuhliso. Nokuba uyibeka phambiliixabiso, ukuqina, okanye ukuchaneka, ukusebenzisana ne-ane ethembekileyoI-China Ibhola yeVenkile yeVenkileIziqinisekiso sokufikelela kwizisombululo zomsebenzi ophezulu.

Amashishini afuna ukulawulwa kokuhamba okuthembekileyo, ukutyala imali kumgangathoUbungakanani beBhola yeBhola enkuluukusuka kwiqinisekisiweyoumvelisisisigqibo sobuchule esiphucula ukusebenza ngokukuko nokhuseleko.
