Cov yeeb nkab fittings yog cov cuab yeej sib txuas ntawm cov kav dej, ua cov ntsiab lus sib txuas ntawm cov khoom thiab cov kav dej. Lawv ua lub luag haujlwm tseem ceeb hauv cov yeeb nkab fittings thiab yog ib qho ntawm ob lub ntsiab ntawm cov kav dej hydraulic. Cov yeeb nkab fittings yog siv rau kev sib txuas ncaj nraim hauv cov twj paj nruag, thiab lwm yam, nrog rau txoj kev sib txuas nrog rau lub qhov (socket) welding lossis threaded txuas. Lawv feem ntau yog siv nyob rau hauv me me - txoj kab uas hla, qis - cov kav dej siab, hauv cov cheeb tsam uas xav tau kev sib dhos thiab sib cais, lossis rau kev hloov kho zaum kawg hauv cov kav dej siv threaded fittings. Cov qauv txheej txheem nyiam yog hlau-rau- hlau tiv thaiv kev sib khi; gasket sealing qauv feem ntau yog siv rau hauv cov kav dej thauj dej, roj, cua, thiab lwm yam, thiab yog ua los ntawm cov hlau cam khwb cia hlau. Tsis tas li ntawd, kev siv cov kev xav tau thiab tus nqi kuj yog qhov tseem ceeb rau kev txiav txim siab thaum xaiv fittings.
Muaj ntau ntau hom yeeb nkab fittings, feem ntau muab faib ua cov yeeb nkab fittings thiab hloov tau yooj yim hose fittings. Raws li txoj kev sib txuas ntawm kev sib txuas ntawm cov yeeb nkab thiab cov yeeb nkab, cov yeeb nkab fittings muaj xws li flared, compression, thiab welded hom, hose flexible hose fittings feem ntau crimped hose fittings.
Txoj kev sib txuas ntawm cov kav dej thiab cov yeeb nkab fittings hauv hydraulic systems kuj txawv; tus ntsia hlau- kawg ntawm cov yeeb nkab siv cov xov txuas. Tapered threads, nruj nrog lawv lub khob hliav qab -zoo li tus qauv thiab sealing nrog cov ntaub ntawv zoo li PTFE, feem ntau yog siv nyob rau hauv qis - mus rau nruab nrab - hydraulic systems. Cov xov zoo muaj kev sib khi zoo heev thiab feem ntau siv rau hauv siab - lub zog siab, tab sis yuav tsum tau siv cov tshuab ntxhua khaub ncaws los yog O-rings rau kawg- ntsej muag sealing; Qee zaum tooj liab washers kuj siv. Lawv tsim nyog rau kev sib txuas cov kav dej nrog cov phab ntsa tuab. Lawv cov khoom tseem ceeb muaj xws li lub cev haum, cov yeeb nkab txuas, thiab cov txiv ntoo. Hauv kev siv, lub cev haum yog muab tso rau hauv lub hom phiaj, thiab cov tshuab ntxhua khaub ncaws tau hais los saum no yog siv los kaw lub ntsej muag kawg. Roj hmab foob yog siv ntawm lub cev haum thiab cov yeeb nkab txuas; Qee lub sij hawm ib lub raj kheej kheej kuj tseem siv tau.
Vim hais tias cov yeeb nkab fittings yog detachable kev twb kev txuas cov ntsiab lus, nyob rau hauv tas li ntawd mus ntsib raws li cov kev xav tau xws li ruaj khov kev twb kev txuas, muaj zog sealing, tsim nyog loj, tsis tshua muaj siab poob, thiab zoo processability, lawv yuav tsum tau yooj yim rau assemble thiab disassemble. Yog li ntawd, tsis txhob kwv yees cov yeeb nkab me me no, vim tias lawv yog qhov tseem ceeb rau tag nrho cov hydraulic system.
