Iyini i-valve yebhola yensimbi engagqwali?
1. Isimiso sokusebenza se-valve yebhola yensimbi engagqwali
I-valve yebhola yensimbi engagqwali wuhlobo olusha lwevalvu esetshenziswa kabanzi. Umgomo wokusebenza we-valve yebhola yensimbi engagqwali ukuzungezisa umgogodla we-valve ukwenza i-valve ingavimbeki noma ivinjwe. Ama-valve ebhola ensimbi angenasici kulula ukuwashintsha, amancane ngosayizi, angenziwa abe ngamadayimitha amakhulu, abe nokubeka uphawu okuthembekile, isakhiwo esilula, nokugcinwa kalula. Indawo yokuvala kanye nendawo eyindilinga ihlala isesimweni esivaliwe futhi ayiguguleka kalula yi-medium. Zisetshenziswa kabanzi ezimbonini ezahlukahlukene.
I-valve yebhola yensimbi engagqwali idinga kuphela ukujikeleziswa ngamadigri angama-90 kanye netorque encane ejikelezayo ukuze ivaleke ngokuqinile. I-valve yomzimba we-valve elingana ngokuphelele inikeza indlela yokugeleza eqondile enokumelana okuncane kwe-medium. Isici esiyinhloko se-valve yebhola ukuthi inesakhiwo esihlangene futhi kulula ukuyisebenzisa nokuyigcina. Ama-valve ebhola ensimbi engagqwali angasetshenziswa ukulawula ukugeleza kwezinhlobo ezihlukahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya eyonakalisayo ehlukahlukene, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya ekhipha imisebe. Umzimba we-valve yebhola ungahlanganiswa noma uhlanganiswe.
2. Ukuhlukaniswa kwama-valve ebhola ensimbi engagqwali
Ukuhlukaniswa ngokwamandla:
Insimbi engagqwali i-pneumatic ball valve, i-stainless steel electric ball valve, i-stainless steel manual ball valve.
Ukuhlukaniswa ngokwezinto ezibonakalayo:
304 insimbi engagqwali ibhola valve, 316L insimbi engagqwali valvu ibhola, 321 insimbi engagqwali valvu ibhola, njll.
Kuhlukaniswa ngokwesakhiwo:
(1) Ivalve yebhola entantayo - ibhola levalvu yebhola liyantanta. Ngaphansi kwesenzo sokucindezela okuphakathi, ibhola lingakhiqiza ukugudluka okuthile bese licindezela endaweni yokuvala yokuphela kwe-outlet ukuze kuqinisekiswe ukuvalwa kokuphela kwe-outlet. I-valve yebhola elintantayo inesakhiwo esilula kanye nokusebenza kahle kokuvala, kodwa wonke umthwalo wendawo yokusebenza ebholeni udluliselwa endandatho yokuvala yokuphuma. Ngakho-ke, kuyadingeka ukucabangela ukuthi indandatho yokuvala ingakwazi ukumelana nomthwalo wokusebenza we-ball medium. Lesi sakhiwo sisetshenziswa kabanzi kuma-valve ebhola aphakathi naphansi.
(2) I-valve yebhola engashintshi: Ibhola le-valve yebhola ligxilile futhi alinyakazi ngemva kokucindezelwa. Ibhola elingashintshi kanye namavalvu ebhola wonke anezihlalo zamavalvu ezintantayo. Ngemva kokuba ngaphansi kwengcindezi ephakathi, isihlalo se-valve siyanyakaza, okwenza indandatho yokuvala icindezele ngokuqinile ebholeni ukuze kuqinisekiswe ukuvaleka. Ama-Bearings avame ukufakwa ku-shafts engaphezulu nangaphansi yebhola, ene-torque encane yokusebenza, futhi ifaneleka ku-high-pressure kanye nama-valve-diameter amakhulu. Ukuze kuncishiswe i-torque yokusebenza ye-valve yebhola futhi ukwandise ukuthembeka kophawu, i-valve yebhola evalwe ngamafutha iye yavela. Amafutha okugcoba akhethekile ajojowe phakathi kwezindawo zokuvala ukuze enze ifilimu yamafutha, engagcini nje ukuthuthukisa ukubekwa uphawu, kodwa futhi inciphisa i-torque yokusebenza futhi ifaneleka kakhulu. I-valve yebhola ye-diameter enkulu yokucindezela okuphezulu.
(3) I-valve yebhola enwebekayo: Ibhola le-valve yebhola liyanwebeka. Indandatho yokuvala isihlalo sebhola ne-valve zombili zenziwe ngezinto zensimbi, futhi ingcindezi ethile yokuvala inkulu kakhulu. Ingcindezi ye-medium ngokwayo ayikwazi ukuhlangabezana nezidingo zokuvala, futhi amandla angaphandle kufanele asetshenziswe. Lolu hlobo lwe-valve lufanele ukushisa okuphezulu kanye nemidiya yokucindezela okukhulu. I-elastic sphere ithola ukunwebeka ngokuvula i-elastic groove ekugcineni okungaphansi kodonga lwangaphakathi lwendilinga. Lapho uvala isiteshi, sebenzisa ikhanda elimise okwe-valve lesiqu se-valve ukwandisa ibhola futhi ucindezele isihlalo se-valve ukuze ufinyelele uphawu. Khulula ikhanda elimise okwentshinyela ngaphambi kokuphendula ibhola, futhi ibhola lizobuyela esimweni salo sasekuqaleni, lishiye igebe elincane phakathi kwebhola nesihlalo sevalvu, okunganciphisa ukungqubuzana endaweni evalayo kanye netorque yokusebenza.
Ukuhlukaniswa ngokwendawo yesiteshi:
Ama-valve ebhola angahlukaniswa abe ama-valve ebhola ensimbi engenasici aqonde phakathi, ama-valve ensimbi engenasici enezinhlangothi ezintathu kanye nama-valve ensimbi engenasici ane-engeli yesokudla ngokuya ngezindawo zawo zesiteshi. Phakathi kwawo, ama-valve ebhola lensimbi engenasici enezinhlangothi ezintathu ahlanganisa i-valve yebhola yensimbi engenasici enomumo ongu-T enezimbobo ezintathu kanye ne-valve yensimbi engenasici enomumo ongu-L. I-valve yensimbi engenasici emise okwe-T enezinhlangothi ezintathu ingaxhuma amapayipi amathathu e-orthogonal elinye nelinye futhi inqume umzila wesithathu ukuze iphambukise futhi ihlanganise ukugeleza. Ivalvu yensimbi engenasici enomumo ongu-L ingakwazi ukuxhuma amapayipi amabili ahambisanayo, futhi ayikwazi ukugcina ukuxhuma kwepayipi lesithathu ngesikhathi esifanayo. Idlala indima yokusabalalisa kuphela.
Kuhlukaniswe ngokokwakheka:
I-valve yebhola yensimbi engagqwali eneziqephu ezimbili, ivalvu yebhola yensimbi engenasici eneziqephu ezintathu.
