Yintoni ivalve?
Isivingco sisixhobo esisebenza ngoomatshini esilawula ukuhamba kunye noxinzelelo kwinkqubo okanye kwinkqubo. Zizinto ezisisiseko zenkqubo yemibhobho yokuhambisa ulwelo, igesi, umphunga, udaka, njl.
Nikezela ngeentlobo ezahlukeneyo zezivalo: ivalve yesango, ivelufa yokumisa, iplagi yevali, ivelufa yebhola, ivelufa yamabhabhathane, ivelufa yokujonga, ivalufa yovalo, ivelufa yempintshi, ivelufa yokuhambisa uxinzelelo, ivelufa yolawulo, njlnjl. Kukho iimodeli ezininzi zohlobo ngalunye, nganye inezinto ezahlukeneyo imisebenzi kunye nemisebenzi. Ezinye iivelufa ziyazisebenza, ngelixa ezinye zisebenza ngesandla okanye ngee-actuator okanye i-pneumatic okanye i-hydraulic.
Imisebenzi yesivalo yile:
yima kwaye uqale inkqubo
ukunciphisa okanye ukwandisa ukuhamba
ulawulo ulwalathiso
lawula ukuhamba okanye inkqubo yoxinzelelo
Inkqubo yokubhobhoza ukukhupha uxinzelelo oluthile
Zininzi uyilo lwevalve, iintlobo kunye neemodeli, ezinoluhlu olubanzi lwezicelo zeshishini. Yonke idibana nomsebenzi omnye okanye ngaphezulu echazwe apha ngasentla. Ivaluva zizinto ezibizayo, kubalulekile ukucacisa ivelufa echanekileyo yomsebenzi, kwaye ivelufa kufuneka yenziwe ngezinto ezichanekileyo kulwelo lonyango.
Nokuba luhlobo luni, zonke iivevithi zinezi zinto zilandelayo: umzimba, ibhonethi, itrim (izinto zangaphakathi), iactuator kunye nokupakisha. Izinto ezisisiseko zevalvu zibonisiwe kulo mzobo ungezantsi.
Ivelufa sisixhobo esisetyenziselwa ukulawula ulwalathiso, uxinzelelo kunye nokuhamba kolwelo kwinkqubo yolwelo. Sisisixhobo esenza ukuba ukuhamba (ulwelo, igesi, umgubo) kuphume okanye kuyeke kumbhobho nakwizixhobo kwaye kungalawula ukuhamba kwayo.
Ivalve yinxalenye yolawulo kwinkqubo yokuhamba kolwelo lombhobho, esetyenziselwa ukutshintsha icandelo lesitishi kunye nolwalathiso lokuhamba okuphakathi. Inemisebenzi yokuphambukisa, ukunqunyulwa, ukujija, ukujonga, ukukhupha okanye ukukhulula uxinzelelo. Zininzi iintlobo kunye nokubalulwa kwezivalo zolawulo lwamanzi, ukusuka kwivevter yokumisa elula ukuya kwinkqubo yolawulo oluzenzekelayo. Ububanzi begama levalve luvela kwivelufa yesixhobo esincinci kakhulu ukuya kumbhobho wevali yombhobho enobubanzi obufikelela kwi-10m. Ingasetyenziselwa ukulawula ukuhamba kwamanzi, umphunga, ioyile, igesi, udaka, imithombo yeendaba etshabalalisayo, isinyithi esingamanzi kunye nolwelo olunemitha yeathom. Uxinzelelo olusebenzayo lwevalve luvela kwi-0.0013mpa ukuya kwi-1000MPa, kwaye ubushushu obusebenzayo bungavela kwi-c-270 ukuya kwi-1430 ℃.
Ivalve inokulawulwa ziindidi zeendlela zokudlulisela, ezinje ngemanyuwali, umbane, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electromagnetic, i-electro-hydraulic, i-pneumatic, i-spur gear, i-bevel gear drive, njl. iimfuno, okanye ivule ngokulula okanye ivale ngaphandle kokuxhomekeka kumqondiso woluvo. Ivelufa ixhomekeke ekuqhubeni okanye kwindlela ezenzekelayo yokwenza ukuba iindawo zokuvula nokuvala zihambe ziye ezantsi, zityibilike, zijike okanye zijikeleze, ukuze utshintshe ubungakanani bendawo yejelo layo ukuze uqonde umsebenzi wayo.
