2 Tsim
2.1 Cov qauv
Cov khoom kaw (nplaim npauj npaim) ntawm npauj npaim valve yog nyob rau hauv nruab nrab ntawm qhov nruab nrab, thiab nws cov kev cuam tshuam ntawm kev khiav hauj lwm yuav tsum tau txiav txim siab hauv qhov tsim.
2.1 Cov qauv
Cov khoom kaw (nplaim npauj npaim) ntawm npauj npaim valve yog nyob rau hauv nruab nrab ntawm qhov nruab nrab, thiab nws cov kev cuam tshuam ntawm kev khiav hauj lwm yuav tsum tau txiav txim siab hauv qhov tsim.
Hais txog tus qauv ntawm tus npauj npaim phaj ntawm qhov loj-inch npauj npaim valve, AWWA C504 (American Water Supply Engineering Association Standard) qhia tias npauj npaim phaj yuav tsum tsis txhob muaj cov kab rov tav, thiab nws cov tuab yuav tsum tsis txhob siab dua 2.25 npaug ntawm txoj kab uas hla ntawm lub phaj npauj npaim. valve qia.
Cov dej nkag los thiab qhov dej tawm ntawm lub phaj npauj npaim yuav tsum tau streamlined.
Cov ntsia hlau sab hauv tuaj yeem tsis tuaj yeem tawm sab nraum lub phaj npauj npaim, thiaj li tsis ua kom cov dej-ntsej muag ntau ntxiv.
2.2 Roj hmab foob

Cov ntsia hlau sab hauv tuaj yeem tsis tuaj yeem tawm sab nraum lub phaj npauj npaim, thiaj li tsis ua kom cov dej-ntsej muag ntau ntxiv.
2.2 Roj hmab foob
Qee lub sij hawm lub neej kev pab cuam ntawm cov roj hmab npauj npaim valve yog luv, uas muaj feem xyuam rau cov roj hmab zoo thiab qhov dav ntawm qhov sealing nto.Lub nplhaib sealing ntawm cov roj hmab-sealed npauj npaim valve yuav tsum tau ua los ntawm cov khoom siv roj hmab zoo, thiab cov txheej txheem yuav tsum tau ua raws li cov txheej txheem compression molding.Lub vulcanization kub yuav tsum tsis txhob arbitrarily nce, thiab lub sij hawm yuav luv luv, txwv tsis pub nws yuav yooj yim ua rau lub sealing nplhaib rau hnub nyoog thiab tawg.Cov hlau sealing nto txuam nrog cov roj hmab sealing nplhaib yuav tsum muaj qhov dav txaus, txwv tsis pub cov roj hmab sealing nplhaib tsis yooj yim rau embedded.Tsis tas li ntawd, cov duab thiab txoj hauj lwm kam rau ua, symmetry, precision, smoothness, thiab elasticity ntawm sealing nplhaib ntawm lub valve lub cev thiab npauj npaim phaj kuj cuam tshuam rau lub neej kev pab cuam ntawm roj hmab sealing nplhaib.
2.2 Kev nruj
Kev nruj yog ib qho teeb meem tseem ceeb hauv kev tsim cov npauj npaim li qub, uas muaj feem xyuam rau cov yam ntxwv xws li daim hlau npauj npaim, lub valve shafts thiab kev sib txuas.

(1) Valve ncej loj Lub valve ncej loj yog teev nyob rau hauv AWWA C504.Yog hais tias qhov loj ntawm lub valve ncej tsis ua raws li qhov yuav tsum tau muaj, tej zaum yuav tsis txaus rigidity, thim rov qab seal to, thiab qhib lub zog loj.Lub zog ntawm cov ncej muaj feem xyuam nrog 1 / EI, uas yog hais tias, txhawm rau txhim kho qhov tawv thiab txo qhov teeb meem deformation, peb yuav tsum pib los ntawm kev nce EI.E yog lub modulus ntawm elasticity.Feem ntau, qhov sib txawv ntawm cov hlau tsis loj, thiab cov khoom xaiv tau muaj kev cuam tshuam me ntsis rau qhov nruj.Kuv yog lub sij hawm ntawm inertia thiab muaj feem xyuam rau seem loj ntawm lub ncej.Qhov loj ntawm lub valve ncej feem ntau yog xam raws li kev sib xyaw ua ke ntawm kev khoov thiab torsion.Nws tsis yog tsuas yog cuam tshuam nrog lub zog torque, tab sis kuj tseem cuam tshuam nrog lub sijhawm khoov.Tshwj xeeb, lub sijhawm khoov ntawm qhov loj-ntev npauj npaim valve yog qhov loj dua li lub zog.
(2) Kev sib koom ua ke ntawm lub qhov taub Qhov qub ntawm AWWA C504 qhia tias tus npauj npaim valve ncej yog qhov ncaj.Tom qab xyoo 1980, nws tau hais tias nws tuaj yeem ua rau ob lub luv luv.Raws li AWWA C504 thiab GB12238, embedded ntev ntawm ncej thiab qhov yuav tsum yog 1.5d.Qhov sib txawv (C tus nqi) ntawm ntug ntawm lub valve lub cev thiab qhov kawg ntawm lub phaj npauj npaim nyob rau hauv axial dimension ntawm Japanese npauj npaim valve yog teev, uas feem ntau muaj feem xyuam rau qhov loj ntawm txoj kab uas hla, uas yog nyob nruab nrab ntawm 25 thiab 45 hli. , uas yog txhawm rau txo qhov kev ncua deb ntawm cov ncej txhawb nqa (C tus nqi), yog li txo lub sijhawm khoov thiab deformation ntawm cov ncej.
(3) Npauj npaim phaj qauv Cov qauv ntawm lub phaj npauj npaim muaj kev sib raug zoo nrog cov rigidity, yog li ntxiv rau cov phaj tiaj tiaj, nws feem ntau yog ua rau hauv lub lauj kaub los yog lub truss duab.Nyob rau hauv luv luv, nws yog ua kom lub sij hawm ntawm inertia ntawm seem kom rigidity.
(4) Valve lub cev qauv tseem muaj teeb meem nruj hauv kev tsim ntawm lub cev loj-inch npauj npaim valve lub cev.Feem ntau, muaj cov nplhaib ribs thiab cross ribs.Qhov tseeb, tus ntoo khaub lig tav tsuas yog nce qhov kev ruaj ntseg thiab yuav tsum tsis txhob ntau dhau.Cov tseem ceeb yog cov nplhaib ribs.Yog tias koj tuaj yeem ntxiv ∩-zoo li tus tav, nws yuav muaj txiaj ntsig zoo dua rau kev nruj, tab sis muaj teeb meem ntawm kev tsim khoom tsis zoo.
2.3 Tus kheej lubricating bearings
Feem ntau los yog tag nrho cov nruab nrab siab ntawm lub phaj npauj npaim (rov qab) yog kis mus rau cov kabmob los ntawm cov ncej, yog li cov kabmob ua lub luag haujlwm tseem ceeb heev.Qee qhov txawv teb chaws npauj npaim li qub yog lub teeb thiab siv tau, thiab cov khoom siv me me tuaj yeem tig nrog ib tus ntiv tes, thaum qee qhov npauj npaim li qub yog hnyav.Ntxiv rau qhov coaxiality, symmetry, kev ua tiav, tiav thiab qhov zoo ntawm cov ntim khoom, nws yog ib qho tseem ceeb heev yog lub lubrication ntawm lub tes tsho khoom.AWWA C504 tus qauv qhia tias lub tes tsho los yog cov kabmob ntsia tau rau hauv lub cev lub cev yuav tsum yog cov khoom siv lubricating tus kheej, thiab lub tes tsho ncej muaj qhov teeb meem ntawm kev sib txhuam thiab lubrication, thiab corrosion tsis kam.Yog tsis muaj lub tes tsho, txawm tias lub valve ncej yog stainless hlau, lub valve lub cev muaj xeb thiab adhesion teeb meem.Kev siv cov bushings tuaj yeem ua rau kom muaj zog.
