Indilinga ene-eksisi engaguquki ibizwa ngokuthi i-fixed sphere. Ibhola elilungisiwe lisetshenziselwa ikakhulukazi ukucindezela okuphezulu kanye nobubanzi obukhulu. Izici ezimbili ezibaluleke kakhulu zamabhola e-valve ukujikeleza nokuqeda phezulu. Ukuyindilinga kufanele kulawulwe ikakhulukazi endaweni yokuvala uphawu. Siyakwazi ukwenza amabhola e-valve anendilinga ephezulu kakhulu kanye nokubekezelelana kokuqeda okuphezulu.
Yiziphi izinhlobo esingazenzela amabhola e-valve
Amabhola amavalvu antantayo noma ama-trunnion, amabhola aqinile noma angenalutho, amabhola evalve ahlezi phansi noma ensimbi, amabhola anezikhala noma ane-splines, namanye amabhola akhethekile kukho konke ukumiswa noma amabhola aguquliwe noma imininingwane ongayiklama.
Umsebenzi we-sphere ongashintshi:
1. Ukusebenza kwebhola okungashintshi konga umzamo. Ibhola lisekelwa ama-bearings angaphezulu naphansi ukuze kuncishiswe ukungqubuzana nokuqeda i-torque eyeqile ekhiqizwa umthwalo omkhulu wokuvala obangelwa ukwethulwa kwengcindezi yokuphusha ibhola neshidi lokuvala.
2. Ukusebenza kokubekwa uphawu kwebhola elingaguquki kuthembekile. I-PTFE indandatho yokuvala into engezona ezocansi ishumekwe esihlalweni sevalvu yensimbi engagqwali, futhi zombili iziphetho zesihlalo sevalvu yensimbi zineziphethu zokuqinisekisa ukuthi indandatho yokuvala inamandla anele okuqinisa ngaphambilini. Uma indawo yokuvala i-valve igqoke ngesikhathi sokusetshenziswa, i-valve izoqhubeka nokuqinisekisa ukusebenza okuhle kokuvala ngisho nangaphansi kwesenzo sentwasahlobo.
3. Ukuvikelwa komlilo: Ukuze uvimbele indandatho yokuvala ye-PTFE ukuthi ingashi ngenxa yokushisa okungazelelwe noma umlilo, kuzokwenzeka inani elikhulu lokuvuza, okuzobhebhethekisa umlilo, futhi indandatho yokuvala engangeni umlilo ibekwe phakathi kwebhola ne-valve. isihlalo, nendandatho yokuvala ishiswe. Ngalesi sikhathi, ibhola elilungisiwe licindezela ngokushesha indandatho yokuvala isihlalo se-valve ngokumelene nebhola ngaphansi kwesenzo samandla asentwasahlobo, futhi yakha uphawu lwensimbi-yensimbi olunomphumela othile wokuvala. Ukuhlolwa kokumelana nomlilo kuhlangabezana nezidingo zamazinga e-AP16FA kanye ne-API607.
4. Ukunciphisa ukucindezela okuzenzakalelayo: Uma ukucindezela kwendawo egciniwe ku-valve cavity ikhuphuka ngokungavamile futhi idlula amandla okuqinisa ngaphambilini entwasahlobo, isihlalo se-valve siya emuva futhi sisuka ebhola, ngaleyo ndlela idedela ukucindezela ngokuzenzakalelayo. Ngemuva kokuthi ingcindezi ikhululiwe, isihlalo se-valve sizobuya ngokuzenzakalelayo
5. Ukuthuthwa kwamanzi: Hlola ukuthi azikho yini izimbobo zokudonsa amanzi phezulu nangaphansi emzimbeni webhola elingashintshi, nokuthi isihlalo sevalvu siyavuza yini. Ngesikhathi somsebenzi, uma ibhola elihleliwe livuliwe ngokuphelele noma livalwe ngokuphelele, ukucindezela emgodini ophakathi kungakhululwa futhi ukupakisha kungashintshwa ngokuqondile. Ungakwazi ukukhipha i-retentate emgodini ophakathi ukuze unciphise ukungcoliswa kwe-valve nge-medium.
Izicelo:
Amabhola e-Xinzhan valve asetshenziswa kuma-valve ebhola ahlukahlukene asetshenziswa emkhakheni we-petroleum, igesi yemvelo, ukwelashwa kwamanzi, imboni yezokwelapha kanye namakhemikhali, ukushisa, njll.
Izimakethe Ezinkulu:
Russia, South Korea, Canada, United Kingdom, Taiwan, Poland, Denmark, Germany, Finland, Czech Republic, Spain, Italy, India, Brazil, United States, Israel, njll.
Ukupakishwa:
Amabhola e-valve amancane: ibhokisi le-blister, iphepha lepulasitiki, ibhokisi lephepha, ibhokisi lepulangwe le-plywood.
Ukuze uthole amabhola ama-valve amakhulu: isikhwama sebhamuza, ibhokisi lephepha, ibhokisi lepulangwe le-plywood.
Ukuthunyelwa:
ngolwandle, ngomoya, ngesitimela, njll.
Inkokhelo:
ngu-T/T, L/C.
Izinzuzo:
- Ama-oda amasampula noma ama-oda amancane omzila angaba ozikhethela wona
- Izinsiza ezithuthukile
- Uhlelo oluhle lokuphatha ukukhiqiza
- Ithimba lezobuchwepheshe eliqinile
- Amanani entengo anengqondo futhi angabizi
