Hauv cov txheej txheem ua haujlwm, cov xov sib txuas yog cov khoom siv tseem ceeb uas siv los koom nrog cov khoom siv uas tswj cov kua lossis roj hloov pauv. Cov khoom siv no muaj cov helical grooves machined rau ntawm sab nraud (txiv neej) lossis sab hauv (poj niam), ua kom muaj kev sib txuas ruaj ntseg thiab tiv taus qhov xau. Thaum sib koom ua ke, cov xov tsim cov khoom siv sib txuas ruaj khov uas muaj peev xwm tiv taus ntau yam kev ntxhov siab ua haujlwm.
Cov xov sib txuas tsis yog tsuas yog tuav cov khoom ua ke xwb tab sis kuj tiv thaiv kom tsis txhob muaj dej xau. Muaj ob hom xov tseem ceeb: xov sib luag thiab xov taper. Txhua hom sib txawv hauv geometry thiab sealing mechanism.
Xov Sib Npaug
Kuj hu ua xov ncaj, xov sib luag muaj lub cheeb thiab cov qauv xov sib xws raws lawv qhov ntev tag nrho. Cov duab sib xws no ua rau kev sib phim thiab kev teeb tsa yooj yim dua. Txawm li cas los xij, vim tias cov xov tsis taper, nws tsis tsim lub foob los ntawm kev sib zog radial. Hloov chaw, nws yuav vam khom cov khoom siv sib khi - xws li O-ring, gasket, lossis washer - kom tiv thaiv kev xau hauv kev siv siab. Lub luag haujlwm tseem ceeb ntawm cov xov yog los muab lub zog kho tshuab. Qhov kev tsim no ua rau cov xov sib luag zoo rau cov ntawv thov uas xav tau kev sib dhos thiab kev rho tawm ntau zaus, vim tias lub foob hloov tau yooj yim rau kev saib xyuas yam tsis ua rau cov xov puas tsuaj.
Xov Taper
Xov taper yog machined nrog lub maj mam txo txoj kab uas hla, tsim ib daim ntawv conical. Thaum txiv neej thiab poj niam Cheebtsam koom nrog, lub taper tsim ib tug wedging nyhuv uas ua rau kom cov xov sib cuag thiab tsim kom muaj kev cuam tshuam mechanical. Qhov radial compression no tsim ib tug hlau-rau-hlau foob, uas ua rau nruj dua nyob rau hauv siab, ua rau cov xov taper zoo heev nyob rau hauv high-pressure lossis dynamic systems uas muaj roj los yog kua. Lub sealing kev ua tau zoo ntawm cov xov taper zoo dua nrog rau tightening thiab siab nce, tshem tawm qhov xav tau ntxiv seals nyob rau hauv ntau daim ntawv thov.
Kev Xav Txog Kev Xaiv
Cov xov sib luag feem ntau nyiam siv rau hauv cov tshuab uas muaj qhov siab qis lossis qhov twg qhov sib txawv thiab yooj yim ntawm kev saib xyuas tau muab qhov tseem ceeb. Nws yog ib qho tseem ceeb uas yuav tsum xaiv cov gaskets lossis O-rings uas sib xws kom ntseeg tau tias muaj qhov xau.
Cov xov taper zoo heev nyob rau hauv qhov chaw muaj kev kub siab, tshwj xeeb tshaj yog nyob rau hauv hydraulic, pneumatic, lossis cov txheej txheem kua dej. Lawv lub peev xwm kaw tus kheej hauv qab kev kub siab ua rau lawv yog qhov kev xaiv txhim khu kev qha nyob rau hauv cov xwm txheej nyuaj.
Rau kev teeb tsa cov twj paj nruag, cov qauv xov feem ntau suav nrog Metric thiab BSPP (parallel), nrog rau NPT thiab BSPT (tapered). Thaum xaiv hom kev sib txuas, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov xwm txheej ua haujlwm, qib siab, thiab kev sib raug zoo nrog cov kab ke uas twb muaj lawm. Nrog ntau tshaj 20 xyoo ntawm kev paub hauv kev tsim cov twj paj nruag ntsuas,Shanghai Wangyuanmuaj ntau yam xov xaiv rau cov transmitters thiab txhawb kev teeb tsa kev cai rau kev sib txuas ntawm cov txheej txheem. Thov koj xav tiv tauj peb yog tias koj xav paub ntxiv lossis xav tau tshwj xeeb.
