Hlukanisa nesakhiwo

Ivalve yebhola yocezu olulodwa iyibhola elihlanganisiwe, indandatho ye-PTFE, nanadi lokukhiya.I-diameter yebhola incane kakhulu kunepayipi, 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.Iziqephu ezintathui-valve yebholayehlukile ku-valve yebhola eneziqephu ezimbili kanye ne-valve yebhola yesiqephu esisodwa ngoba kulula ukuyiqaqa nokuyinakekela.

Hlukanisa nengcindezi

Ukumelana nokucindezela kohlobo lwezicucu ezintathu kuphakeme kakhulu kunokwengxenye eyodwa kanye nezingcezu ezimbiliama-valve ebhola.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 kanye nokusebenza kahle kokuvala, kodwa umthwalo wendilinga ephethe i-interface yokusebenza wonke udluliselwa eringini yokuvala, ngakho-ke kuyadingeka ukucabangela ukuthi impahla yokuvala indandatho ingamelana yini nomthwalo wokusebenza i-sphere 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.Ngemuva kokucindezela kwe-medium, isihlalo se-valve siyanyakaza, ukuze indandatho yokuvala icindezelwe ngokuqinile ebholeni ukuze kuqinisekiswe ukuvalwa.Ama-bearings avame ukufakwa ku-shafts ephezulu nangaphansi ye-sphere, futhi i-torque yokusebenza incane, efanelekile kuma-valve aphezulu kanye nobubanzi obukhulu.Ukuze kuncishiswe i-torque yokusebenza ye-valve yebhola futhi kwandiswe ukuthembeka kophawu, ama-valve ebhola avalwe ngamafutha avele.Amafutha okugcoba akhethekile ajovwe phakathi kwezindawo zokuvala ukuze enze ifilimu kawoyela, ethuthukisa ukusebenza kokuvala futhi yehlise itorque yokusebenza, okuyenza ifaneleke kakhulu ukucindezela okuphezulu.I-valve yebhola ye-caliber.

3. I-valve yebhola enwebekayo: Ibhola le-valve yebhola liyanwebeka.Kokubili ibhola nendandatho yokuvala isihlalo se-valve zenziwe ngezinto zensimbi, futhi ingcindezi ethile yokubeka uphawu inkulu kakhulu.Ingcindezi ye-medium ngokwayo ayikwazi ukuhlangabezana nezidingo zokuvala, futhi amandla angaphandle kufanele asetshenziswe.Le valve ifanele ukushisa okuphezulu kanye nemidiya yokucindezela okuphezulu.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 indilinga, futhi imbulunga izobuyela esimweni sayo sasekuqaleni, ukuze kube negebe elincane phakathi kwendilinga kanye nesihlalo sevalvu, okunganciphisa ukungqubuzana kwendawo yokuvala kanye netorque esebenzayo.

Ama-valve ebhola angahlukaniswa abe uhlobo oluqondile, uhlobo lwezindlela ezintathu kanye nohlobo lwe-engeli yesokudla ngokuya ngokuma kwesiteshi.Okokugcinaama-valve amabili ebholaasetshenziselwa ukusabalalisa i-medium futhi aguqule isiqondiso sokugeleza kwe-medium.
