Tube xov tsis muaj xov foob
Rau cov uas tsis yog-xov-sealed yeeb nkab threads, ob sab hauv thiab sab nraud threads yog cylindrical yeeb nkab threads. Cov cim cim yog raws li nram no: Xov feature code, dimension code, kam rau ua qib code-roj code, xov feature code yog sawv cev los ntawm G, thiab loj code yog 1/2, 3/4, 1, ... txhais tau tias. Cov xov tooj kam rau ua qib code: Muaj ob qib ntawm cov qhab nia rau cov xov sab nraud, A thiab B, thiab tsis muaj cov cim rau cov xov sab hauv. Thaum cov xov yog sab laug, ntxiv LH ntawm sab nraub qaum, txoj cai-tes xov tsis raug cim nrog cov kev taw qhia ntawm kev sib hloov txoj cai, thaum cov xov sab hauv thiab sab nraud tau sib sau ua ke, cov cim ntawm cov xov sab hauv thiab sab nraud yog sib cais los ntawm slashes. , sab laug sawv cev rau cov xov sab hauv, sab xis sawv cev rau cov xov sab nraud.
Xov-sealed yeeb nkab xov
Muaj ob hom kev sib txuas rau cov yeeb nkab threads kaw nrog xov: conical sab nraud xov, conical internal thread thiab cylindrical internal thread. Muaj ob hom kev sib txuas: conical internal thread thiab conical sab nraud xov, thiab cylindrical internal thread thiab conical sab nraud xov yog matched. Marking: Rc txhais tau tias conical internal thread, Rp txhais tau tias cylindrical internal thread, thiab R txhais tau hais tias conical sab nraud xov. , Qhov loj code yog sawv cev los ntawm 1/2, 3/4, 1, 11/2, ... Thaum cov xov yog sab laug, ntxiv LH, thiab txoj cai-tes threads tsis cim nrog cov kev taw qhia ntawm kev sib hloov code. Thaum cov xov sab hauv thiab sab nraud tau sib sau ua ke, cov cim ntawm cov xov sab hauv thiab sab nraud yog sib cais los ntawm kab pheeb ces kaum, sab laug qhia cov xov sab hauv, thiab sab xis qhia cov xov sab nraud. Piv txwv li, yog hais tias lub cylindrical internal xov yog txuam nrog conical sab nraud xov (sab xis), lub cim yog Rp3/4 / R3 / 4.

Nws yog hais txog lub cylindrical yeeb nkab xov uas nws cov xov tsis kaw. Cov xov tsis-xov kaw cov yeeb nkab feem ntau yog siv hauv dej, roj kav dej, lubrication thiab xaim piping tshuab nrog lub siab qis dua 1.57MPa. Kev kaw cov yeeb nkab xov txhais tau hais tias lub cev threaded muaj lub kaw cov yeeb nkab xov, thiab cov yeeb nkab xov kaw nrog cov xov feem ntau yog siv rau hauv qhov kub thiab txias, kev kub siab thiab lubrication tshuab.
