PVC SADDLE SHAMS yog qhov tseem ceeb fittings rau cov yeeb nkab ceg sib txuas, thiab lawv lub siab tsis kam cuam tshuam ncaj qha cuam tshuam kev nyab xeeb system. Cov Txheeb Xyuas muaj kwv yees tias kwv yees li 30% ntawm cov yeeb nkab to kev sib tsoo yog tshwm sim los ntawm cov fittings tsis txaus. Yog li ntawd, tshawb xyuas cov txheej txheem kev ua kom muaj feem cuam tshuam rau cov kev ua tau zoo no tuav cov khoom muaj nqis uas tseem ceeb.
I. Cov Qauv Tseem Ceeb thiab Qauv Ua Haujlwm
1.1 Cov Txheej Txheem Yooj Yim
A PVC SADDOW CDRO TAMPMas muaj cov ntu hauv qab no:
Eeb puag: Ib feem hauv kev sib cuag nrog lub yeeb nkab loj, feem ntau tsim nrog semicircular lossis eeb {0} Tus kab nkhaus nkhaus kom haum rau sab nraud ntawm cov yeeb nkab loj.
Chaw nres nkoj ceg chaw nres nkoj: Qhov hluav taws xob rau kev sib txuas cov kav dej ceg, feem ntau yog ua rau cov qauv threed los yog qauv.
Clamping Mechanism: Ib qho cuab yeej siv los kho lub eeb yeem rau lub yeeb nkab tseem ceeb, feem ntau muaj nyob rau hauv ob hom: Bolt {{free wedge {{} tsau.
SOLDING KOOM TES: Feem ntau muaj los ntawm EPDM roj hmab seuing nplhaib, nyob rau ntawm thaj chaw tiv tauj ntawm lub eeb thiab lub ntsiab yeeb nkab kom ntseeg tau tias kev sib khi ua tau zoo.
Qhov Cuab Lub Zog Tus Qauv: Qee qhov siab - lub siab shaddle clams yog tsim nrog kev txhawb nqa cov kab ke lossis cov kab hlau kom txhim kho cov zog tag nrho thiab kav ntev.
1.2 Tus Qauv Ua Haujlwm thiab Txoj Kev Sib Txuas
Tus txheej txheem ua haujlwm ntawm lub tshuab kaw tshuab clamp yog raws li kev sib koom tes clamping thiab kev sib koom tes sib txuas. Nws cov txheej txheem ua haujlwm yooj yim yog raws li hauv qab no:
Cov Txheej Txheem Txheej Txheem: Ua ntej, tho ib lub qhov yeeb nkab, tom qab ntawd haum lub eeb hauv qab, thiab ruaj ntseg lub eeb ntxab rau cov yeeb nkab siv lub tshuab clamping.
Sealing Mechaism: Raws li qhov kev txiav txim ntawm clamping quab yuam sab hauv lub eeb cdle yog compressed clamp thiab lub ntsiab yeeb nkab, sib sau kev sib khi ntawm kev sib khi.
Ncau ceg: Lub ceg yeeb nkab txuas nrog los ntawm cov ceg chaw nres nkoj ntawm lub eeb clamp los tsim cov yeeb nkab ua tiav.
Raws li kev clamping,PVC SADDLE SHAMSfeem ntau muab faib ua ob hom:
Bolt -} clamped hom: Siv Bolts thiab txiv ntoo kom txhim kho lub eeb kom haum rau lub ntsiab yeeb nkab, nrog clamping yuam kho los ntawm kev tswj lub bolt torque.
Ii. Cov Txheej Txheem Tseem Ceeb Cuam Tshuam
2.1 Cov Khoom Siv Lub Cev Thiab Phab Ntsa Thickness
Ntaub ntawv:
PVC {- u (unplasticized polyvinyl chloside (tab sis kuj muaj zog (compressive muaj zog: 40-55 mpa).
Impact-Modified PVC: Improves toughness and impact resistance by adding impact modifiers, suitable for high-pressure environments.
PVCO (Biaxially Oriented Polyvinyl chloride): Kev siv zog txhim kho cov tshuab tshwj xeeb uas los ntawm kev ua haujlwm tshwj xeeb thiab kev nqus khoom zoo dua li siv PVC dog dig.
Phab Ntsa Thickness:
Thaum lub phab ntsa tuab ntawm lub taub hau tu siab nce los ntawm 3 hli mus rau 5 hli, lub siab tsis kam ntawm lub eeb yeem tuaj yeem txhim kho los ntawm 40%.
Lub phab ntsa tuab ntawm cov ceg chaw pov thawj yuav tsum tau 20 -}}}}}}}} dua li ntawd ntawm lub teeb cig los txhim kho nws lub peev xwm tiv thaiv.
Raws li Astm cov qauv, rau kev nyuaj pob zeb nrog lub ntsej muaj ib lub nroog me (DN) tsawg dua 110mm, qhov tsawg kawg nkaus phab ntsa tuab yuav tsum tsis pub tsawg tshaj 3.2mm; Rau cov neeg uas muaj DN ntawm 110mm thiab 315mm, qhov tsawg kawg nkaus phab ntsa tuab yuav tsum tsis pub tsawg tshaj li 4.5mm.
2.2 Clamping Mechanism
Clamping yuam:
Nws yuav tsum tau compress cov nplhaib sib khi los ntawm 20-30% kom ua tiav kev sib khi tau zoo. Tshaj 80% ntawm cov khoom siv cov txiaj ntsig zoo yuav ua rau muaj kev cuam tshuam yooj yim.
Ib plaub - point bolt clamping tsim tau los ntawm kwv yees li ntawm clamping kev faib tawm, vim tias nws muab cov kev faib tawm tshiab.
Hom:
Bolt -} clamped hom: Tso cai rau kev kho clamping coriling thiab yog tsim rau cov kav dej ntawm ntau qhov diameters, tab sis muaj kev faib tsis ncaj (nquag rau kev ntxhov siab ".
Npoo -} Cov Hom Tsha: Cov nta tau yooj yim installation thiab tus neeg muaj zog sib npaug, nrog rau ib lub zog loj ntawm lub kaum sab xis ntawm 15-20 degras, tab sis nws cov kev kaw lub zog yog qhov nyuaj rau kev tswj hwm thiab yuav tsum tau siab tsim kev cim.
Clamp -} clamped hom: Muaj kev faib tawm cov zog uas muaj zog thiab tsim nyog rau loj {0} tus qauv ntawm cov kav dej uas hla dhau 10% siab dua li lub pob taws kub {}} clamped hom).
2.3 Cov qauv khaws cia
Sealing nplhaib:
EPDM (ethylene diene monomer) Roj hmab: Muaj cov huab cua zoo tsis kam, thiab siv tshuaj lom neeg thiab cov tshuaj pov tseg (siab txog li 1.6 MPa ntawm chav tsev kub).
Roj hmab Silicone: cov khoom pov thawj siab zoo heev {{degree tsis kam (tswj elasticity (tswj elasticity ntawm -50℃ntawm -50 degree) tab sis tsis tshua muaj tshuaj tiv thaiv corrosion dua epdm.
Cov lus pom zoo: EPDM sealing rings nrog lub hardness ntawm 60-7: ntug dej hiav txwv (sib npaug kev sib tw ua tau zoo thiab txo qis kev puas tsuaj rau lub pvc nto).
Fuam Groove:
Qhov tob: 70-80% ntawm kev sib khi ntiv nplhaib lub taub (kom paub tseeb tias ib qho 20-30% compression tus nqi).
Dav: 10 {- dua li 15% loj dua li cov nplhaib sib khi lub hau (kom tsis txhob muaj cov nplhaib sib khi).
Txoj Haujlwm: Nyob ntawm qhov siab - siab sab ntawm kev sib tiv tauj saum npoo ntawm lub eeb thiab cov yeeb nkab loj (rau txoj kev sib khi hauv nruab nrab).
III. Xaus thiab Outlook
Los ntawm kev tshawb nrhiav nruam thiab kev tsim kho tshiab, lub siab tsis kam thiab tag nrho kev ua tau zoo ntawmPVC SADDLE SHAMSYuav ua kom zoo dua qub, muab cov muaj zog tuaj yeem lav rau kev nyab xeeb thiab txhim khu kev qha ntawm kev nyab xeeb ntawm ntau cov yeeb nkab.
