Yintoni ivalve yebhabhathane?

IIbhotile yebhabhathaneyakhiwe eUnited States nge-1930s. Yaziswa eJapan ngo-1950s kwaye yayingasetyenziswanga ngokubanzi eJapan de kube ngu-1960. Khange ithandwa kwilizwe lam kude kube ngama-1970. Iimpawu eziphambili zeValve zebhabhathane zezi: I-Torque encinci, indawo encinci yokufakelwa kunye nobunzima bokukhanya. Ukuthatha i-DN1000 njengomzekelo,Ibhotile yebhabhathaneimalunga ne-2t, ngelixaI-Palve yesangoimalunga ne-3.5t. IIbhotile yebhabhathaneKulula ukudibanisa izixhobo ezahlukeneyo ze-drive kwaye kukho ukuqina okuhle kunye nokuthembeka. I-vally yebhabhathane etywiniweyo yebhulethi kukuba xa isetyenziselwa ukuqaqamba, i-cavication iyakwenzeka ngenxa yokusetyenziswa okungalunganga, kubangela isitulo serabha ukuba siphose kwaye sonakaliswe. Ke ngoko, indlela yokukhetha ngokuchanekileyo kuxhomekeka kwiimeko zomsebenzi. Ubudlelwane phakathi kokuvulwa kwevalve yebhabhathane kwaye ireyithi yokuhamba ihambelana ngokusisiseko. Ukuba isetyenziselwa ukulawula inqanaba lokuhamba, iimpawu zalo zokuhamba ezinxulumene ngokusondeleyo nokunganyangeki kwendlela yokuhamba. Umzekelo, ukuba i-valiber caliber kunye nefom yemibhobho emibini iyafana, kodwa ilahleko ye-Pipenel Elahlekileyo yahlukile, umgangatho wokuhamba kwevali uya kwahluka kakhulu. Ukuba ivalve ikwimo ye-ampling enkulu ye-ampling, i-cavication ithathelwe ukuba ibe senzeka ngasemva kweplate ye-valve, enokwenzakalisa ivalve. Isetyenziswa rhoqo ngaphandle kwe-15 °. XaIbhotile yebhabhathaneKukuvulwa okumbindi ophakathi, imilo yokuvula eyenziwa ngumzimba wevalve kunye nesiphelo sangaphambili seplate yebhabhathane igxile kwi-vall, kwaye amazwe ahlukeneyo enziwa kumacala omabini. Isiphelo sangaphambili seplate yebhabhathane kwelinye icala lihamba kwicala lokuhamba kwamanzi, kwaye elinye icala lihamba kwicala lokuhamba kwamanzi. Ke ngoko, i-veli ibhulukhwe kunye neplate ye-valve kwelinye icala lenza i-nozzle-ivule ivumba, kwaye elinye icala liyafana nokuvuleka komngxunya. Icala le-nozzle linenqanaba lokuhamba ngokukhawuleza okukhulu kunecala lokuhamba kwamadini, kwaye uxinzelelo olubi luya kwenziwa phantsi kwevalve kwi-tendettle kwicala lokuhlambela, kwaye itywina lerabha lihlala liwela. I-torque esebenzayo yeIbhotile yebhabhathaneiyahluka ngenxa yokuvuleka okwahlukileyo kunye nokuvula kunye nokuvala ivalve. I-torque iveliswe ngumahluko phakathi kweentloko ezingaphezulu zebhabhathane eziphezulu zebhabhathane, ngakumbi ivalve enkulu yedabi, ngenxa yobunzulu bamanzi, ayinakutyeshelwa. Ukongeza, xa i-elbow ifakwe kwindawo yokungena kwivalve, ukuhamba kwekhefu, kwaye itota iya kukhula. Xa ivalve ikwindawo yokuvula ephakathi, indlela yokusebenza kufuneka ibe kukuzilalela ngenxa yesenzo sokuhamba kwamanzi.

I-China inamakhonkco amanqam amaninzi evalve, kodwa ayinamandla evali. Ngokubanzi, ilizwe lam lingene kwiindawo ezinamagunya evalve zehlabathi, kodwa ngokomgangatho wemveliso, ilizwe lam isekude ukuba linamandla evali. Eli shishini lisenalo uxinzelelo lwemveliso ephantsi, i-R & D ye-R & D ye-R & D i-valves ehambelana neemveliso zokuphela, kunye netekhnoloji yetekhnoloji yokuthengisa ephantsi kumzi-mveliso we-Valve, kunye nentsilelo yorhwebo ngaphandle nangasezorhwebo nokuthumela ngaphandle nangasezorhwebo nokuthengisa ngaphandle nangasezorhwebo nokuthengisa ngaphandle nangazizwe ngaphandle nangazizwe Ngokuqinisekileyo kukho iinkampani ezininzi zeValve ezinokuphila ngokwenene kwintengiso. Nangona kunjalo, ukothusa isantya esiphezulu kumzi-mveliso we-vali kuya kuzisa amathuba amakhulu, kwaye iziphumo zothusa ziya kwenza umsebenzi wentengiso ngakumbi. Indlela eya ekuhlangeneyo yeevalve ezikwi-valves ephezulu "ibuhlungu". Amacandelo asisiseko abe sisithinteli esithintela ukuphuculwa kweshishini lemveliso yelizwe lam ukuya kuphele. Ngexesha leminyaka eli-12 yeminyaka emihlanu, urhulumente uza kuqhubeka nokwandisa indawo yokuhlala izixhobo zokuphela. Apha sikhetha izinto ezininzi eziphambili kwi "Isicwangciso sokumiliselwa" kunye namashishini eValve omele iVove kuhlalutyo olunokwenzeka lokungenisa elizweni. Ukusuka kuhlalutyo, kunokubonwa ukuba ukufakwa kwentsholongwane kumashishini ahlukeneyo ahluka kakhulu, kwaye iiVooves eziphezulu ngokungxamisekileyo zifuna isikhokelo somgaqo-nkqubo kunye nenkxaso yophando.

Umzi mveliso weveli udlala indima ebaluleke kakhulu njengekhonkco elibalulekileyo kumzi-mveliso wokusebenza kwezixhobo kuphuhliso loqoqosho lweSizwe. Kuba inqanaba lemveliso yokwenziwa kwe-valve yeli lizwe lisekude ukusuka kwinqanaba eliphezulu lehlabathi, isitshixo esikhuluivaliNgeparamitha ephezulu, ubushushu obuphezulu kunye noxinzelelo oluphezulu, kunye nenqanaba eliphezulu leyunithi lihlala lixhomekeke kwinkcitho. Umzekelo, uphawu lwe-European olungu-Europe lwaseYurophu luhlala lukhetho oluphambili lweshishini lokufaka isicelo sellove lasekhaya. Ukwenzela ukukhuthaza ukwenziwa kweeValves, emva kokuba iBhunga likaRhulumente likhuphe "izimvo ezininzi zokukhawulezisa ukuvuselelwa kwemveliso yezixhobo", amasebe kaRhulumente afanelekileyo enze uthotho lweemfuno zombuso. I-LED yeKhomishini yeSizwe yoPhuculo kunye noTshintsho, uMbutho woMatshini we-China Dedeneration kunye noMatshini weShishini leShishini leShishini le-China igqityiwe kwaye yakha i-AivalveIsicwangciso sokuqala sezixhobo eziphambili kumacandelo ahambelana nawo, kwaye silungelelaniswe namasebe afanelekileyo amaxesha ngamaxesha. Ngoku indawo yokufakwa kweegelvu isenze imvumelwano kumzi-mveliso we-valve wasekhaya. Ukwamkela ngenkuthalo imigangatho yehlabathi yoyilo lwemveliso; I-Arsurb yeZiko loyilo lwangaphandle Uvavanyo lwemveliso kunye nokuhlolwa kwenkqubo kwenziwa ngokungqinelana nemigangatho yamazwe ngamazwe; ukubamba inkqubo yemveliso yangaphandle kunye nokunamathisela ukubaluleka kuphando kunye nokukhuthaza izinto ezintsha; Chaza iiparamitha zobugcisa kunye neemeko zokusebenza zemveliso engeniswe ngayo iVoodve, njl njl. Ngokukhawulezisa isantya sohlengahlengiso kumzi-mveliso we-valve, umzi-mveliso wexesha elizayo uya kuba kukhuphiswano phakathi kwemveliso yeValve kunye nezokhuseleko neMveliso yeMveliso. Iimveliso ziya kuphuhlisa kwicala letekhnoloji ephezulu, iiparamitha eziphezulu, ukuxhathisa okuqinileyo, kunye nobomi obude. Kuphela kukwahlulelwa kweTekhnoloji kuphela, ukuphuhliswa kweemveliso ezintsha, kunye nenguqu kwezobugcisa kunokwenzeka ukuba itekhnoloji yetekhnoloji yemveliso iphuculwe ngokuthe ngcembe ukuhlangana nesixhobo sefowuni yasekhaya kwaye siqonde ngokupheleleyo ukwenziwa kweevalves. Ngaphantsi kwemeko enkulu yemfuno, ishishini lokwenza i-valve livele leli lizwe liya kubonisa ukuba lingcono lophuhliso.
