Lub kaw lus ntsiag to yog lub valve tsis siv neeg uas tswj qhov qhib thiab kaw ntawm lub valve disc raws li cov kev taw qhia ntawm qhov nruab nrab ntws, tso cai rau unidirectional ntws thiab tiv thaiv rov qab. Nws cov qauv tsim ua tiav kev ua haujlwm ntsiag to los ntawm kev ua haujlwm sab hauv ntws channel thiab luv luv -stroke valve disc:
Forward Flow: Nruab nrab siab thawb lub valve disc qhib, tso cai rau cov kua dej ntws zoo raws li cov channel streamlined nrog tsawg kawg nkaus poob.
Rov qab Flow: Lub valve disc kaw sai sai nyob rau hauv nws tus kheej qhov hnyav, qhov rov qab siab ntawm nruab nrab, thiab lub caij nplooj ntoos hlav quab yuam, thaiv kev thim rov qab thiab zam lub suab nrov los ntawm lub valve disc cuam tshuam hauv cov khoom qub.
Core Structural Advantages
Kev ua tau zoo nyob ntsiag to: Los ntawm kev txhim kho cov qauv (xws li qeeb - kaw lub valve disc thiab mos- cov ntaub ntawv foob), suab nrov yog tswj ntawm 20-40dB (ze rau ib puag ncig hauv tsev qiv ntawv), qis dua li 30-60dB ntawm cov khoom siv tshuaj xyuas ib txwm muaj. Haum rau suab nrov-sensitive scenarios:
Cov Khoom Siv Hauv Tsev: Tsis txhob muaj suab nrov cuam tshuam los ntawm kev tso quav tso quav, lub tshuab ntxhua khaub ncaws, thiab lwm yam.
Kev Kho Mob thiab Chaw Ua Haujlwm: Cov chav tsev kho mob, chav kuaj, thiab cov tshuab cua txias hauv nruab nrab hauv cov tsev ua haujlwm yuav tsum muaj qhov chaw nyob ntsiag to.
Siab -Kev Tiv Thaiv Backflow thiab Kev Tiv Thaiv Kab Mob
Teb ceev ceev: Lub valve disc ua rau kaw thaum pib ntawm qhov rov qab, tiv thaiv siab - cov xov xwm siab los ntawm kev cuam tshuam lub twj tso kua mis lub cev, cov khoom siv hluav taws xob, thiab lwm yam khoom siv.
Stable Sealing: Rubber or PTFE soft-seal valve seats reduce the risk of leakage, suitable for water supply, drainage, HVAC, and other systems with high sealing requirements.
Kev txuag hluav taws xob thiab Flow Resistance Optimization: Txoj kev ncaj nraim - los ntawm kev tsim channel ntws txo qhov nruab nrab ndlwg kuj coefficient los ntawm 30% -50%, txo cov twj siv zog los ntawm 10% -20%, thaum ua kom ruaj khov ntws nrawm, tsis txhob muaj kev hloov pauv siab, thiab txuas ntxiv lub neej ntawm cov kav dej thiab cov khoom siv.
Installation Flexibility thiab Adaptability
Free Angle Installation: tuaj yeem ntsia tau kab rov tav, ntsug (nruab nrab ntws mus rau sab saud), lossis ntawm lub kaum sab xis, haum rau qhov chaw - txwv qhov xwm txheej xws li cov kav dej hauv tsev thiab cov khoom siv chav.
Kev Pabcuam Dav Dav: Cov khoom lag luam paub tab muaj los ntawm DN15 (hauv tsev) mus rau DN600 (kev lag luam), ua tau raws li qhov xav tau ntawm txhua yam los ntawm kev siv dej hauv tsev mus rau kev lag luam.
Daim ntawv thov scenarios thiab xaiv cov lus pom zoo
Siv tau Scenarios
Tsawg- Ib puag ncig suab nrov: Cov khoom siv dej hauv tsev, tsev kho mob, tsev so, chaw ua haujlwm hauv nruab nrab cua txias tshuab. Cov kab ke uas muaj lub zog siab - txuag cov kev xav tau: cov khoom siv dej thiab cov kav dej, HVAC, thiab cov kav dej tiv thaiv hluav taws. Txo cov dej tsis kam ua kom qis zog noj.
Cov txheej txheem huv huv: Cov xov xwm tsis muaj qhov tsis huv, xws li dej kais dej, dej huv huv, thiab dej txias zoo tib yam.
High-temperature/highly corrosive environments: Conventional products are temperature resistant from -10℃ to 120℃, but cannot be used in steam systems (>150 degree) los yog muaj zog acid / alkali media (xws li hydrochloric acid thiab sodium hydroxide tov).
Cov xov xwm uas muaj cov impurities: av nkos, xeb, vuam slag, thiab lwm yam, tuaj yeem ua rau lub pob valve yooj yim los yog sealing nto hnav, yuav tsum tau siv lub lim.
Tsawg- qhov kub thiab txias: Hauv qab -10 degree, roj hmab seals harden, thiab qeeb-kaw mechanism yuav khov, ua rau foob tsis ua hauj lwm los yog suab nrov rebound.
Loj - txoj kab uas hla, siab - cov tshuab ua haujlwm siab: Cov khoom siv saum toj no DN200 tau txo cov suab nrov vim yog cov xov xwm loj thiab qhov nrawm nrawm, yuav tsum tau ua kom yooj yim hydraulic qeeb- kaw tshuab, nce nqi ntau.
Cov kev xaiv tseem ceeb:
Khoom siv: Stainless hlau lossis hlau alloy rau kev cob qhia tshuaj; tshav kub-resistant alloy steel rau siab-kub cov kav dej.
Flow thiab Pressure: Txiav txim siab qhov nominal txoj kab uas hla raws li cov kav dej ntws ntws kom tsis txhob muaj qhov nrawm nrawm lossis qeeb qeeb; lub nominal siab yuav tsum siab tshaj los yog sib npaug rau qhov system khiav hauj lwm siab.
Kev Txhim Kho thiab Kev Kho: Xaiv kab rov tav, ntsug, lossis inclined installation txoj kev raws li cov raj xa dej; Thaum qhov chaw muaj tsawg, ua qhov tseem ceeb ntawm wafer- hom kev sib txuas lossis cov valves compact.
