Koj xav tau lub valve rau cov kab kev lag luam lossis cov kab tshuaj lom neeg, tab sis koj tsis paub tseeb tias cov yas puas tuaj yeem tswj tau qhov siab. Kev xaiv lub valve tsis raug tuaj yeem ua rau muaj kev xau txaus ntshai, lub sijhawm tsis ua haujlwm kim heev, thiab muaj xwm txheej kev nyab xeeb loj.

Lub pob valve PP zoo, zoo li peb cov qauv Pntek, muaj qhov ntsuas siab PN16. Qhov no txhais tau tias nws tuaj yeem tswj tau 16 bar (kwv yees li 235 PSI) ntawm qhov kub thiab txias hauv chav. Qhov tseem ceeb, lub peev xwm no txo ​​qis thaum qhov kub ntawm cov kua dej nce siab.

Thaum kuv tham nrog cov neeg koom tes zoo li Eric Lim hauv Malaysia, qhov ntsuas siab tsis yog ib tus lej xwb; nws yog hais txog kev nyab xeeb thiab kev ntseeg siab. Nws lub tuam txhab muab cov haujlwm thoob plaws sab hnub tuaj Asia, thiab lawv yuav tsum paub tias cov khoom uas lawv muag yuav tsis ua tsis tiav. Qhov ntsuas siab ntawm lub valve yog qhov pib, tab sis qhov kev txawj ntse tiag tiag yog nyob rau hauv kev nkag siab tias nws ua li cas hauv qab lub ntiaj teb tiag tiag. Kev paub no yog qhov sib cais kev lag luam yooj yim thiab kev koom tes tiag tiag, thiab nws yog qhov peb tsom mus rau ntawm Pntek.

Qhov ntsuas siab ntawm lub pob valve yog dab tsi?

Koj pom cov lus zoo li CLASS 150, PN16, thiab CWP ntawm cov ntawv qhia txog cov ntaub ntawv thiab koj xav tias koj tsis meej pem. Qhov kev tsis meej pem no tuaj yeem ua rau koj yuam kev xaj lub valve tsis raug, ua rau lub kaw lus tsis muaj kev nyab xeeb rau koj tus neeg siv khoom.

Ib qho ntsuas siab qhia koj tias qhov siab tshaj plaws uas lub valve tuaj yeem tswj tau ntawm qhov kub tshwj xeeb. Cov qauv sib txawv xws li PN (European), Class (American), thiab CWP (General) siv, yog li koj yuav tsum paub tias koj tab tom saib lub kaw lus twg.

Cia peb piav qhia cov lus no kom meej vim nws yooj yim dua li nws zoo li. Qhov ntsuas siab yog qhov tseem ceeb tshaj plaws rau kev nyab xeeb rau txhua lub valve. Txawm li cas los xij, ntau qhov chaw ntawm lub ntiaj teb thiab ntau yam kev lag luam siv cov txheej txheem sib txawv, uas tuaj yeem ua rau tsis meej pem. Rau cov kav dej yas, koj feem ntau yuav pomPNkev ntsuas. "PN" sawv cev rauKev Tshaj Tawm Nomination, uas yog lus Fab Kis rau Nominal Pressure. Nws qhia txog qhov siab tshaj plaws hauvlub bartias cov khoom no tuaj yeem tiv taus qhov kub thiab txias hauv chav tsev (20 ° C). Lwm qhov kev ntsuas feem ntau yogCWP, lossis Kev Ua Haujlwm Txias Siab. Qhov no zoo ib yam li PN, qhia koj qhov siab tshaj plaws rau qhov kub thiab txias. Rau cov twj siv hauv kev lag luam lossis hlau, koj yuav pom ib qhoChav Kawmqhov ntsuas (piv txwv li, Chav Kawm 150, Chav Kawm 300), uas yog tus qauv Asmeskas (ANSI) uas txhais cov kev txwv siab thoob plaws ntau qhov kub thiab txias. Rau peb txoj haujlwm, kev tsom mus rau PN yog qhov tseem ceeb.

Cov Txheej Txheem Ntsuas Siab

Qhov ntsuas siab rau cov khoom siv polypropylene yog dab tsi?

Koj tau lees tias koj lub valve yog lawm, tab sis cov khoom siv txuas nws ne? Ib lub kaw lus tsuas muaj zog npaum li nws cov khoom tsis muaj zog tshaj plaws, thiab qhov sib txuas tsis sib xws tuaj yeem ua rau muaj kev puas tsuaj loj.

Cov khoom siv polypropylene kuj raug ntsuas siv lub kaw lus PN, feem ntau yog PN10 lossis PN16. Rau lub kaw lus txhim khu kev qha, qhov ntsuas siab ntawm koj cov khoom siv thiab cov kav dej yuav tsum sib npaug lossis ntau dua qhov ntsuas ntawm koj cov li qub.

Kuv ib txwm ceeb toom Eric Lim tias lub valve tsis ua haujlwm ib leeg. Koj tab tom tsim ib qholub kaw lusYog tias koj nruab ib lub pob valve PN16 uas muaj zog tab sis txuas nws nrogPN10 cov khoom siv, koj lub kaw lus tag nrho lub zog ua haujlwm siab tshaj plaws tam sim no tsuas yog PN10 (10 bar). Qhov tsis muaj zog tshaj plaws qhia txog lub zog ntawm tag nrho cov saw hlau. Qhov no yog vim li cas peb thiaj ua kom peb PntekPP pob valveyog PN16 khov kho. Qhov no muab lub hauv paus ruaj khov, tab sis nws yog qhov tseem ceeb heev uas yuav tsum tau txuas nrog PN16 cov kav dej thiab cov khoom siv kom tswj tau qhov muaj peev xwm siab thoob plaws hauv kab. Qhov tseem ceeb tshaj plaws, tshwj xeeb tshaj yog nrogcov thermoplasticszoo li polypropylene, yog qhov kub. Thaum cov kua kub dua, cov khoom siv yuav mos dua, thiab nws lub peev xwm tuav qhov siab poob qis heev. Qhov no hu ua 'derating', thiab koj yuav tsum ua raws li cov lus qhia ntawm cov chaw tsim khoom.daim ntawv qhia txog qhov siab-kubua haujlwm kom muaj kev nyab xeeb.

Lub pob valve tuav tau pes tsawg psi?

Koj tsuas xav tau ib lo lus teb yooj yim hauv PSI xwb, tab sis cov lus qhia feem ntau yog "bar" lossis "PN". Kev hloov pauv sai sai hauv koj lub taub hau yog qhov txaus ntshai thaum kev nyab xeeb thiab kev ua haujlwm ntawm cov khoom siv tseem ceeb.

Qhov no txawv ntau heev, txij li 150 PSI rau qee cov yas valve mus txog ntau tshaj 10,000 PSI rau cov hlau siab tshwj xeeb. Txhawm rau nrhiav PSI, hloov los ntawm PN qhov ntsuas: 1 bar yog kwv yees li 14.5 PSI.

Tsis muaj ib lo lus teb rau lo lus nug no, yog vim li cas nws thiaj li tseem ceeb heev uas yuav tsum xyuas seb lub valve twg koj siv. Cov khoom siv (PP, PVC, Tooj dag, Stainless Steel), qhov loj me, thiab kev tsim qauv txhua yam hloov cov lus teb. Txawm li cas los xij, peb tuaj yeem ua rau nws yooj yim heev rau peb cov khoom. Peb lub PntekPP pob valveyog ntsuas PN16. Kev hloov pauv yooj yim, thiab txhua tus neeg hauv koj pab neeg yuav tsum paub nws: tsuas yog muab tus nqi bar los ntawm 14.5. Yog li, qhov ntsuas PN16 txhais tau tias lub valve tuaj yeem tuav 16 bar ntawm qhov siab. Txhawm rau nrhiav PSI, koj xam: 16 bar x 14.5 PSI / bar = 232 PSI. Peb feem ntau puag ncig qhov no rau235 PSIrau tus lej meej thiab muaj kev nyab xeeb. Qhov no yog qhov ntsuas ntawm qhov kub thiab txias ib puag ncig. Yog tias koj tus neeg siv khoom hauv Kuala Lumpur khiav dej ntawm 60 ° C (140 ° F) los ntawm kab, qhov ntsuas 235 PSI ntawd tsis siv tau lawm. Lub siab nyab xeeb yuav qis dua, raws li qhia ntawmderating nkhaus.

Kev Hloov Pauv PN rau PSI Feem Ntau

Kev Ntsuas PN	Siab hauv Bar	Siab hauv PSI (kwv yees li)
PN10	10 bar	145 PSI
PN16	16 bar	235 PSI
PN20	20 bar	290 PSI
PN25	25 bar	362 PSI

Lub pob valve PP yog dab tsi?

Koj pom PVC thiab CPVC li qub nyob txhua qhov chaw, yog li koj xav paub tias vim li cas koj yuav tsum xav txog PP. Yog tsis paub txog cov txiaj ntsig tshwj xeeb ntawm polypropylene txhais tau tias koj yuav plam qhov kev daws teeb meem zoo tshaj plaws rau koj tus neeg siv khoom.

Lub pob valve PP yog lub valve uas tig ib feem plaub ua los ntawm polypropylene, ib yam thermoplastic uas muaj nqis rau nws txoj kev tiv thaiv tshuaj lom neeg zoo kawg nkaus. Nws yog ib qho kev xaiv ruaj khov, tsis hnyav, thiab pheej yig rau kev tswj cov kua dej uas yuav ua rau cov valve hlau puas tsuaj.

Lub zog loj ntawm Polypropylene yog nws txoj kev tiv taus tshuaj lom neeg. Nws sawv zoo nkauj tiv taus ntau yam kua qaub, cov hauv paus, ntsev, thiab cov tshuaj lom neeg hauv kev lag luam. Qhov no ua rau nws yog cov khoom siv mus rau hauv kev lag luam xws li kev ua tshuaj lom neeg, kev kho dej, thiab kev ua liaj ua teb. Ntawm Pntek, peb pom lub peev xwm thiab txiav txim siab ua kom zoo tshaj plaws. Peb tau tsim peb tus kheejPP Compression Pob Valveraws li kev tsim pwm tshwj xeeb, patented. Qhov no muab rau peb tag nrho kev tswj hwm qhov zoo thiab kev ua tau zoo. Ib qho tseem ceeb yog peb txoj kev cog lus rau aPN16 qib rau txhua qhov loj me, txij li qhov me tshaj plaws mus rau qhov loj tshaj plaws. Qhov no tsis tshua muaj nyob hauv kev ua lag luam, tab sis peb ntseeg tias kev nyab xeeb thiab qhov zoo yuav tsum sib xws. Qhov no yog qhov laj thawj tseem ceeb uas peb cov li qub yog cov neeg muag khoom zoo tshaj plaws hauv kev lag luam thoob plaws sab hnub tuaj Asia, Middle East, thiab South America. Lawv muab kev daws teeb meem txhim khu kev qha thiab pheej yig rau kev tswj cov tshuaj lom neeg thiab dej kom muaj kev nyab xeeb.
