Yuav ua li cas txheeb xyuas peb hom yeeb nkab xov

Kev tsim kho kev lag luam kua system yog inseparable los ntawm covinstrumentation yeeb nkab fittingsraws li kev sib txuas. Hauv ntau daim ntawv thov xws li ib puag ncig kev kub ntxhov, kev ua haujlwm hnyav lossis kev thauj mus los ntawm cov pa roj-kua, cov duab me me ntawm threaded fittings tuaj yeem pom nyob txhua qhov chaw. Lawv cov kev ua tau zoo heev hauv kev ua haujlwm siab, kev vibration tsis kam thiab sealing pab cov kua dej ua haujlwm zoo dua thiab ruaj khov, ua rau lawv ntseeg tau thiab siv los ntawm ntau tus neeg.

Txhawm rau tsim kom muaj cov kua dej nyab xeeb, lub hauv paus yog xaiv cov xov kom raug. Yog tias koj xav xaiv cov xov zoo, koj yuav tsum txheeb xyuas nws ua ntej.

Hom xov hom Hikelok 

Hom xov hom Hikelok

Muaj ob hom xov uas feem ntau siv los ntawm Hikelok, ib qho yog txuas xov, uas tau muab faib ua M xov thiab UN xov, thiab lwm yam yog cov xov yeeb nkab, uas tau muab faib ua NPT xov, BSPP xov thiab BSPT xov. Daim ntawv no tsuas yog sivcev xovua piv txwv.

Hom yeeb nkab threads

(1) NPT xov(American National Standard Pipe Thread), siv ASME B1 20.1 tus qauv, cov hniav profile kaum sab xis yog 60 °, cov hniav saum toj thiab hauv qab yog nyob rau hauv lub dav hlau xeev, thiab taper ntawm conical xov yog 1 ∶ 16, uas feem ntau hu ua taper xov. .

(2) BSPP xov, sib xws rau G xov (British Standard Parallel Pipe), siv ISO 228-1 tus qauv, tus hniav profile lub kaum sab xis yog 55 °, cov hniav saum toj thiab hauv qab yog arc-puab, thiab cov xov sab hauv thiab sab nraud yog cylindrical yeeb nkab xov, uas yog feem ntau hu ua parallel xov.

(3) BSPT xov, sib xws rau R xov (British general sealing yeeb nkab xov), siv ISO 7-1 tus qauv, tus hniav profile lub kaum sab xis yog 55 °, cov hniav saum toj thiab hauv qab yog ncig arc, thiab taper ntawm conical xov yog 1∶16. Feem ntau hu ua taper xov.

Yuav ua li cas kom paub meej cov specifications ntawm peb cov yeeb nkab threads

Los ntawm cov ntaub ntawv saum toj no, peb tuaj yeem paub tias cov yeeb nkab xov kuj tuaj yeem muab faib ua ob pawg: taper xov thiab cov xov sib txuas. Yog li ntawd, thaum sib txawv xov, peb yuav tsum xub paub qhov txawv seb lawv yog taper xov los yog parallel xov.

Kev txheeb xyuas ua ntej

Kev txiav txim ua ntej tuaj yeem ua raws li seb cov xov puas muaj taper. Siv lub vernier caliper ntsuas lub cheeb ntawm cov lus qhia hniav ntawm thawj, plaub thiab kawg tag nrho xov raws li txoj hauj lwm qhia hauv daim duab hauv qab no. Yog tias txoj kab uas hla maj mam nce lossis txo qis, nws qhia tau tias cov xov muaj taper, uas yog BSPT xov lossis NPT xov hauv cov xov taper. Yog hais tias tag nrho cov diameters yog tib yam, nws qhia tau hais tias cov xov tsis muaj taper thiab yog ib tug tib yam xov BSPP xov.

Kev lees paub ntxiv

Muaj tsuas yog ib qho BSPP xov rau cov xov sib txuas, yog li nws yuav tsum tau ua kom paub qhov txawv ntxiv seb nws yog BSPT xov lossis NPT xov hauv cov xov conical.

Hniav profile angle ntsuas: txiav txim raws li tus hniav profile kaum sab xis, BSPT xov nrog ib tug hniav profile kaum sab xis ntawm 55 ° thiab NPT xov nrog ib tug hniav profile kaum sab xis ntawm 60 °.

BSPT Xov NPT Xov

Saib ntawm cov hniav zoo li: txiav txim raws li cov duab ntawm cov hniav saum toj thiab hauv qab hniav. BSPT xov yog nyob rau sab saum toj thiab puag ncig hauv qab, thiab NPT xov yog nyob rau sab saum toj thiab tiaj tus.

Kev txiav txim zaum kawg

Ob lub cuab yeej hauv qab no yuav tsum tau ua kom paub tseeb tias hom xov.

Txoj Kev 1: siv cov xov ntsuas thiab xaiv cov xov xov sib txuas rau kev pom zoo zaum kawg. Cov xov ntsuas yog zoo kawg nkaus screwed nrog lub xov gauge. Yog hais tias qhov sib thooj xov gauge soj ntsuam cov cai dhau, cov xov specification yog qhov tseeb specification ntawm cov ntsuas xov.

Txoj Kev 2: siv cov hniav ntsuas thiab xaiv cov hniav ntsuas sib xyaw kom sib piv kom txog thaum lub ntsuas hniav haum zoo kawg nkaus nrog cov xov ntsuas, ces cov xov xov yog qhov tseeb ntawm cov xov ntsuas.

Ntxiv nrog rau cov txheej txheem saum toj no, peb tseem tuaj yeem tshawb xyuas cov qauv xov sib txuas ntawm peb cov xov tom qab ntsuas cov xov kab kab uas hla nrog vernier caliper thiab txiav txim siab cov xov taper thiab cov xov sib txuas, thiab tshawb xyuas cov xov tshwj xeeb nrog tib cov xov kab uas hla. raws li cov xov ntsuas hauv cov qauv xov rau kev pom zoo ntxiv, tab sis qhov kev txiav txim zaum kawg tseem xav tau kev pab ntawm xov gauge thiab cov hniav ntsuas.

Thaum muas Hikelok yeeb nkab fittings, nws raug nquahu kom nruab thiab siv nws ua ke nrog Hikelok tswj li qub. Koj tuaj yeem xaivkoob valve, pob valve, proportional nyem valve, metering valve, kos valve, valve manifolds, sampling system, thiab lwm yam, thiaj li ua rau kev sib txuas ntawm cov kua dej muaj kev nyab xeeb thiab ua haujlwm zoo.

Yog xav paub ntxiv txog kev txiav txim, thov mus saib qhov kev xaivcatalogsntawmHikelok lub vev xaib official. Yog tias koj muaj lus nug xaiv, thov hu rau Hikelok's 24-teev cov neeg ua haujlwm muag khoom hauv online.
