Hlukanisa nesakhiwo

Ivalve yebhola yocezu olulodwa iyibhola elihlanganisiwe, indandatho ye-PTFE, nanadi lokukhiya. I-diameter yebhola incane kancane kunaleyo ye-ipayipi, efana ne-valve yebhola ebanzi.

I-valve yebhola eneziqephu ezimbili yakhiwe izingxenye ezimbili, futhi umphumela wokuvala ungcono kunalowo we-valve yebhola elilodwa. Ububanzi bebhola buyafana nobepayipi, futhi kulula ukuqaqa kunevalve yebhola yocezu olulodwa.

I-valve yebhola eneziqephu ezintathu yakhiwe izingxenye ezintathu, ibhonethi nhlangothi zombili kanye nomzimba we-valve ophakathi. I-valve yebhola eneziqephu ezintathu ihlukile kune-valve yebhola eneziqephu ezimbili kanye nesiqephu esisodwai-valve yebholangokuthi kulula ukuhlakaza nokugcina.

Hlukanisa nengcindezi

Ukumelana nokucindezela kwe-valve yebhola lezingxenye ezintathu kuphakeme kakhulu kunaleyo yesiqephu esisodwa kanye nama-valve amabhola amabili. Uhlangothi lwangaphandle lwe-valve yebhola yezingxenye ezintathu eziyinhloko lulungiswa ngamabholithi amane, adlala indima enhle ekubopheni. Umzimba we-valve wokuphonsa oqondile ungafinyelela ingcindezi engu-1000psi≈6.9MPa. Ukuze uthole ingcindezi ephakeme, imizimba yama-valve akhiwe isetshenziswa.

Ngokusho kwesakhiwo se-valve yebhola, ingahlukaniswa ibe:

1. I-valve yebhola entantayo: Ibhola le-valve yebhola liyantanta. Ngaphansi kwesenzo sokucindezela okuphakathi, ibhola lingakhiqiza ukugudluka okuthile futhi licindezele ngokuqinile endaweni yokuvala yokuphela kwe-outlet ukuze kuqinisekiswe ukuthi isiphetho sokuphuma sivaliwe. I-valve yebhola elintantayo inesakhiwo esilula nokusebenza okuhle kokuvala, kodwa umthwalo wendawo yokusebenza ebholeni wonke udluliselwa eringini yokuvala yokuphumayo. Ngakho-ke, kuyadingeka ukucabangela ukuthi impahla yendandatho yokuvala ingamelana nomthwalo wokusebenza we-spherical medium. Lesi sakhiwo sisetshenziswa kabanzi kuma-valve ebhola aphakathi naphansi.

2. I-valve yebhola engashintshi: Ibhola le-valve yebhola ligxilile futhi alinyakazi ngemva kokucindezelwa. I-valve yebhola engashintshi ifakwe isihlalo se-valve esintantayo. Ngemva kokuthola ukucindezela kwe-medium, isihlalo se-valve sizohamba, ukuze indandatho yokuvala igxilwe ngokuqinile ebhola ukuze kuqinisekiswe ukuvala. Ama-Bearings avame ukufakwa ku-shafts ephezulu nangaphansi yebhola, futhi i-torque yokusebenza incane, efanelekile kuma-valve aphezulu kanye nobubanzi obukhulu. Ukuze unciphise i-torque yokusebenza ye-valve yebhola futhi ukwandise ukuthembeka kophawu, i-valve yebhola evalwe ngamafutha yavela. Amafutha okugcoba akhethekile ajovwa phakathi kwezindawo zokuvala ukuze enze ifilimu kawoyela, ethuthukisa ukusebenza kokuvala futhi yehlise itorque yokusebenza, okuyenza ifaneleke kakhulu ukucindezela okuphezulu.I-valve yebholayezinga.

3. I-valve yebhola enwebekayo: Ibhola le-valve yebhola liyanwebeka. I-sphere kanye nendandatho yokuvala isihlalo se-valve zenziwe ngezinto zensimbi, futhi ingcindezi ethile yophawu inkulu kakhulu. Ingcindezi ye-medium ngokwayo ayikwazi ukuhlangabezana nezidingo zokuvala, futhi amandla angaphandle kufanele asetshenziswe. Le valve ifanele ukushisa okuphezulu kanye nemidiya yokucindezela okukhulu. I-elastic sphere yenziwa ngokuvula i-elastic groove engxenyeni engezansi yodonga lwangaphakathi lwendilinga ukuze kutholwe ukunwebeka. Lapho uvala iphaseji, sebenzisa ikhanda elimise okwe-valve lesiqu se-valve ukwandisa ibhola bese ucindezela isihlalo se-valve ukuze uvale. Khulula ikhanda elimise okwe-wedge ngaphambi kokuzungezisa ibhola, futhi ibhola lizobuyela esimweni salo sokuqala, ukuze kube negebe elincane phakathi kwebhola nesihlalo se-valve, okunganciphisa ukungqubuzana kwendawo yokuvala kanye ne-torque yokusebenza.

Ama-valve ebhola angahlukaniswa abe uhlobo oluqondile, uhlobo lwezindlela ezintathu kanye nohlobo lwe-engeli yesokudla ngokuya ngokuma kwesiteshi. Ama-valve amabili okugcina ebhola asetshenziselwa ukusabalalisa okuphakathi nokushintsha isiqondiso sokugeleza kwe-medium.
