Ukuhlelwa kwevalve yepneumaticivalveiimfuno zezinto ezinempembelelo
A, iindidi eziphambili zevalve yepneumatic:
1) Ivalve yokulawula yohlobo lwe-v-umoya
2) Ivalve yokuqhawula i-o-type ye-pneumatic
3) torsion cylinder valve
4) Ivalve yebhabhathane ye-electromagnetic induction pneumatic butterfly
5) inkqubo yokuqhuba i-pneumatic butterfly valve
6) Ivalve yokulawula umbane
Ezimbini, umoya we-v-uhlobo lwevalve elawulayo:
Usetyenziso oluphambili kunye neempawu
A, eyona nto isetyenziswayo yi-bevel rotary structure, yona kunye ne-valve locator exhasa isicelo sezibonelelo, inokugqiba ulungelelwaniso lomlinganiselo; Undoqo wevalve yohlobo lwe-V ilungele zonke iintlobo zeendawo zohlengahlengiso, ezinomlinganiso omkhulu wokuhamba kwe-coefficient, umlinganiselo ohlengahlengiswayo, umphumo wokutywina ulungile kakhulu, iimpawu zohlengahlengiso olubuthathaka, ubungakanani obuncinci, ukufakela ukuxoka okuthe nkqo. Ilungele ukulawula imiphunga, umphunga, ulwelo kunye nezinye izinto.
B, iimpawu: sisakhiwo esijikelezayo se-bevel, esakhiwe nge-v-shaped oil circuit plate, i-actuator ye-pneumatic, i-locator kunye nezinye izincedisi; Kukho iimpawu ezifanayo zangaphambili zokuqukuqela komlinganiselo wekhulu; Ubume obujikelezayo obuphindwe kabini, i-torque eqhubayo incinci, ngokuchaneka okulungileyo kunye nesantya sokufakelwa kwamagnetic; Ubuchule bokusika obugqwesileyo.
I-C, i-pneumatic piston rod actuator yoxinzelelo lomoya njengesixhobo samandla, ngokutsho kwe-piston intonga yokuqina komzimba ukukhuthaza ingalo esongwayo ukuba iqhube i-90 degrees yokujikeleza, ukuze ivalve ivuleke kwaye ivale ngokupheleleyo. Iqukethe: ukulungiswa kwebholiti ye-anchor, i-actuator yezindlu, uhlobo lwengalo egobileyo, umkhono we-cylinder, i-cylinder shaft, intonga ye-piston, i-crankshaft, i-universal shaft.
D, umsebenzi wevalve yokulawula uhlobo lwe-pneumatic yevalve yokulawula ehamba phambili yi-actuator kunye nombutho olawulayo. I-actuator yicandelo lamandla okuqhuba levalve elawulayo, eyenza amandla okuqhuba ahambelanayo ngokobukhulu boxinzelelo lwesignali yedatha yokukhohlisa ukukhuthaza ukulungiswa kokuma kombutho. Ipleyiti yesekethe yeoyile licandelo elilawulayo levalve yokulawula umoya. Ikwachukumisa into elawulayo ukulungelelanisa ukuhamba okupheleleyo kolwelo.
Izinto eziphembelela iimfuno zevalvu
Izinto eziphembelela iimfuno zevalvu
Ukususela ngoJanuwari ukuya kuJuni ngo-2013, i-Wenzhou, indawo yokuvelisa i-valve engundoqo e-China, imveliso yevalve yangaphandle i-8109 iibhetshi, ngokukhula konyaka-ngonyaka we-0.61%, i-quota yokuthumela ngaphandle kwe-260 yezigidi zeedola, ukwehla konyaka-ngonyaka. of 2.98%, ukwehla okuqhubekayo, kwaye ngo-2012, 1-6 Wenzhou valve ukuthunyelwa quota kunyuke ukuya 42%, umsantsa ebalulekileyo phakathi kwamaqela amabini data.
Ivalve efunwa yimekobume yoqoqosho lwehlabathi iyingozi enkulu, intsimi yevalvu yaseTshayina kufuneka izolile, iphucule isakhono sabo sokungenisa nokuthumela ngaphandle kunye nonxibelelwano olusemngciphekweni worhwebo, ngakumbi iimfuno ezisezantsi ngokwentelekiso zobugcisa bemveliso yevalufa eqhelekileyo, ebandakanyeka kwiinkampani ezininzi, imveliso yehomogeneity ingaphezulu. nzulu, imveliso egqithisileyo, inqanaba lengeniso elinciphayo, Iinkampani ezininzi zeevalvu zisekelwe ekwandiseni ukuthunyelwa kwempahla kumazwe angaphandle ukuze zikwazi ukuphila, umlinganiselo wexabiso lokuthumela ngaphandle ivalufa ngokukhula ngokuthe ngcembe.
Kodwa ukwandisa ukuthunyelwa kwempahla kumazwe angaphandle ayisiyiyo ingxaki yophuhliso loshishino lwevalvu ye-panacea, kwakhona kunzima ukunqanda ezinye iingxaki ngokujonga ulwazi lwedatha yokuthumela ngaphandle ebukekayo lubonisa ngokucothayo: uninzi lwenkampani yokuthumela ngaphandle kwevalvu yokwandisa ngokwalo isabelo semarike yokuthumela ngaphandle, ukusuka kukhuphiswano lwamaxabiso emarike yaseTshayina, ukhuphiswano lwamaxabiso olubi. iyaqhubeka ukwanda. Iinkampani ezininzi ezincinci kunye neziphakathi zikhuphisana ngexabiso ukuze zifumane ulwazi lomyalelo wamazwe ngamazwe. Nangona kunjalo, amanye amashishini amancinci naphakathi kwixabiso eliphantsi lemveliso ukufumana iiodolo zaphesheya kolwandle, ukuze kulawulwe ngcono iindleko, zihlala zimbi. Ngenxa yoko, iimveliso ezigqityiweyo azifaneleki kwaye ukuthembeka kwekhonkco loshishino lwevalvu yaseTshayina kusengozini. ** Ukoyikeka kukuba ekuhambeni kwexesha, ikhonkco leshishini le-valve yaseTshayina linokuthi lichaphazeleke kukhuseleko lorhwebo kwimarike yehlabathi.
Ngeli nqanaba, ukuthunyelwa kwe-valve kwamanye amazwe kuhlanjululwa kakhulu kwi-DOLLAR, kwaye umngcipheko wezinga lotshintshiselwano olubangelwa uxabiso lwe-RENMINBI nalo longeza amafutha emlilweni. Abanye abavelisi bevalvu abanawo umgangatho wemveliso oqinileyo, umgunyathi kunye ne-shoddy, benzakalisa ingeniso yoshishino olufanayo e-China kunye nomfanekiso webrand yemveliso ye-valve yase-China yokuthumela ngaphandle. Usizi, okubangele ukuba umda we-valve kuthunyelo kumazwe angaphandle uqhubekile ukwehla.
Ukubuyiswa koqoqosho lwehlabathi kufuneka kube yinkqubo ecothayo, iimfuno zevalvu yimekobume yoqoqosho lwehlabathi inkulu ngokwentelekiso, intsimi yevalvu yaseTshayina kufuneka iphendule ngokuzolileyo ukuphucula ukukwazi ukunxibelelana nemingcipheko yokungenisa kunye nokuthengisa ngaphandle, ekwandiseni ukuthengisa ngaphandle kwangaxeshanye. , Kananjalo ayikwazi ukukhulula uxinzelelo kuphuhliso lwemarike yokuthengisa yaseTshayina. Isiseko senkampani sinokwenza uphuculo lwesakhiwo semizi-mveliso, ukuya kwishishini lemveliso yevalvu ephezulu ukuze iqhubele phambili, njenge-oyile ekrwada, izityalo zamandla enyukliya kunye namanye amashishini ophuhliso angundoqo kazwelonke, iivalvu ezisuka kumazwe angaphandle ubungakanani bemarike obunye obunobunye ayinakungahoywa.
Ngokutsho kwezibalo, kwi-2013, iinkampani zevalvu zaseTshayina zadibana noxinzelelo lokuthumela ngaphandle ukwandisa imeko, iinkampani zevalvu kufuneka zomeleze iteknoloji entsha, ukusuka kwinani lilonke logxininiso, ukwandiswa kwesikali soshishino ukunikela ingqalelo ngakumbi ekufuneni umgangatho ogqibeleleyo, iinzuzo zoqoqosho. , kwaye ngenkuthalo ukuphuhlisa imarike yokuthengisa yaseTshayina, ukukhuthaza indlela yophuhliso olufanelekileyo kwintsimi yesivalo saseTshayina. Kwaye ngokuxhomekeke kwiimfuno zobugcisa zezinye iinkampani ezincinci kunye nobukhulu obuphakathi, zinokuthathela ingqalelo ishishini elitsha lokwahlulahlula, njengokufudumeza imfuno yevalvu yokwahlula amanzi, ukuphucula amandla eeprojekthi zobunjineli ezixhasa izibonelelo, ukwandisa ixabiso elongezelelweyo levalve.
Iimveliso zempompo ze-Ze de centrifugal ukuya kwilifti yogutyulo, umatshini wokuphakamisa amabhakethi amdaka, isikhululo sokuphakamisa amanzi amdaka, isikhululo sempompo esihlanganisiweyo, impompo yokunyusa amanzi amdaka, izixhobo zokuphakamisa ugutyulo, impompo yegadi, impompo yejet, impompo ye-centrifugal, isahluli se-slag, impompo yelindle, impompo ephantsi kwamanzi amdaka njengoko isixhobo esikhokelayo sokuphakamisa ugutyulo. Isixhobo ngasinye sokuphakamisa ugutyulo lwenzelwe ukuba lube lula ngakumbi ukufakela, kwaye kwangaxeshanye, kukho isethi epheleleyo yezixhobo ezifunekayo zokufakela. Sinentengiso evakalayo kwi-Intanethi, inokukuzisela iiprojekthi zenkonzo efanelekileyo, eFransi, eYurophu, uninzi lwaseTshayina lunokugqiba owona mgaqo ukufutshane wokuthenga. Izixhobo zokuphakamisa ugutyulo lwe-Ze de zifanelekile kubantu abaqhelekileyo (usapho), i-villa-family eyodwa, igadi, iinkonzo zorhwebo kunye nezinye iziza, zigxininise kwi-villa engaphantsi kombhobho wokukhupha amanzi, i-drainage efanayo emgangathweni, ukunikezelwa kwamanzi okusela ekhaya, ukunkcenkceshela igadi kunye nezinye iingcali. kunye nezixhobo ezisebenzayo ezidibeneyo zothutho lwamanzi kunye nezisombululo!
