Ivalve njengesixhobo sizalelwe amawaka eminyaka

Ivalvesisixhobo esisetyenzisiweyo kusulelo kunye nolawulo lwegesi kunye nolwelo ubuncinci iminyaka eliwaka yembali.

Okwangoku, kwinkqubo yemibhobho ye-fluid, ivalve elawulayo yinto yokulawula, kwaye umsebenzi wayo ophambili kukuhlula izixhobo kunye nenkqubo yombhobho, zilawula ukuhamba, ukulungisa i-backflow, ilawula kwaye ikhuphe uvavanyo. Kuba kubaluleke kakhulu ukukhetha eyona valve efanelekileyo yenkqubo ye-pipeline, kubaluleke kakhulu ukuqonda iimpawu zevali kunye namanyathelo kunye nokukhetha ivalve.

Uxinzelelo olufanelekileyo lwe-valve

Uxinzelelo oluthile lwevali lubhekisa kuloyilo olunxulumene namandla amacandelo amacandelo, oko kukuthi, luxinzelelo oluvumelekileyo lwevalve kwi-valve. Uxinzelelo lomsebenzi alufani, ke, uxinzelelo oluthile yiparamitha elixhomekeke kwimiba yevali kwaye inxulumene nobushushu obuvumelekileyo bokusebenza kunye noxinzelelo olusebenzayo lwezinto ezibonakalayo.

Ivali yinkqubo ejikelezileyo yokujikeleza okanye inkqubo yoxinzelelo, esetyenziselwa ukulungisa ukuhamba okanye uxinzelelo lwendawo. Eminye imisebenzi ibandakanya ukuva okanye ukutshintshela kwimithombo yeendaba, ukulawula, ukutshintsha kweendaba zokuhamba kweendaba, ukuthintela ukubuyela umva kweMithombo yeendaba, kunye nokulawula okanye uxinzelelo.

Le misebenzi iphunyezwa ngokuhlengahlengisa imeko ye-valve. Olu hlengahlengiso lunokwenziwa ngesandla okanye ngokuzenzekelayo. Umsebenzi wencwadi ukwabandakanya ukusebenza kwento yokulawula ngesandla idrive. Iivalve ezisebenza ngesandla zibizwa ngokuba zii-valves. Ivali ethintela i-backflow ibizwa ngokuba yivalve yokujonga; Lowo ulawula uxinzelelo loncedo ubizwa ngokuba yivalve okanye ivalve yoncedo loKhuseleko.

Ukuza kuthi ga ngoku, i-veli ishishini likwazile ukuvelisa uluhlu olupheleleyo lweI-valves yesangoI-Gloves, i-Globe Valves, i-valve yeplani, i-valve yebhola, i-valves, i-valves, i-valves, iivalves, iivila zokhuseleko, imigibe yokuvalwa kwamava engxamisekileyo. Iimveliso zeVolve eziindidi ezili-12, ngaphezulu kwe-3000 yeemodeli, kunye neenkcazo ezingaphezulu kwe-4000; Olona xinzelelo luphezulu lokusebenza yi-600MPA, ubuncinci be-Diaceter eyi-5350mm, ubushushu obuninzi bokusebenza bungama-1200℃, ubuncinci obunobuncinci bokusebenza bukhona -196℃.

Nika ingqalelo ekukhetheni iveli:

1. Ukwenzela ukunciphisa umhlaba ubunzulu bobunzulu bombhobho,ivalve yebhabhathaneIkhethwe ngokubanzi kumbhobho wobubanzi obuncinci; Eyona nto iphosakeleyo kwivalve yebhabhathane kukuba ipleyiti yebhabhathane ithatha icandelo elithile lamanzi, olonyusa ilahleko ethile yentloko;

I-2. Iivalves eziqhelekileyo zibandakanyaI-Butterfly Valves, I-valves yesango, I-valve yebhola kunye neeplanga, njl njl.

3. Ukuphosa kunye nokulungiswa kweevali zebhola kunye neevali zeplagi kunzima kwaye kuyabiza, kwaye zihlala zilungele imibhobho encinci yedayam. Ivalve yebhola kunye ne-plug valve igcina izibonelelo zevalve yamasango, ukunyangwa kwamanzi amancinci, ukutywinwa okuqinisekileyo, isenzo esiguqulweyo, ukusebenza kakuhle kunye nokugcinwa kakuhle. I-valve yeplagi ikwanedini eliqingqiweyo, kodwa icandelo eligqithileyo lamanzi ayisiyo isangqa esigqibeleleyo.

4. Ukuba ayinampembelelo encinci kubunzulu bomhlaba owukhumbulo, zama ukukhetha ivalve yesango; ukuphakama kwe-qualve yesango lombane yesango elikhulu eliphezulu lesango ichaphazela ubunzulu bomhlaba we-pipeling, kunye nobude besango esikhulu se-diameter eqhubekayo eqhubekayo ngumbhobho kwaye ichaphazela ilungiselelo leminye imibhobho;

I-5. Kwiminyaka yakutshanje, ngenxa yokuphuculwa kwetekhnoloji yokuphosa, ukusetyenziswa kwesanti ye-resen kunokuphepha okanye ukunciphisa ukulungiswa kwendlela, ukuze kuncitshiswe iindleko, ukuze kuncitshiswe iindleko zebhotile enkulu kuko ekuthinjweni. Ngokuphathelele umda we-Deariber of Paraber, kufuneka ithathelwe ingqalelo kwaye yahlulwe ngokwemeko ethile.
