Qhov tseem ceeb sib txawv ntawmib - phajthiabob - phaj check li qublies feem ntau nyob rau hauv lawv cov qauv tsim thiab cov dej ua tau zoo.
Tib - phaj kos li qubsiv ib qho, ib qho kev sib txuas ntawm lub voj voog uas tig ib ncig ntawm lub caj npab rocker rau qhib thiab kaw. Thaum yooj yim nyob rau hauv cov qauv, nrog tsawg qhov chaw thiab yooj yim txij nkawm, lub valve disc muaj ib tug loj loj, yuav tsum tau ib tug ntau dua nruab nrab ndlwg tus nqi rau startup thiab exhibiting tseem ceeb inertia thaum kaw, ua rau nws nquag mus rauj dej.
Muab ob npaug rau- phaj kos li qub, ntawm qhov tod tes, muaj ob lub symmetrical semi-paj valve discs txuas nrog lub ncej. Lawv tuaj yeem qhib thiab kaw ntawm nws tus kheej lossis ib txhij. Qhov ob -disc qauv tso cai rau kev qhib thiab kaw nrawm dua, ua kom ntseeg tau tias qhib txawm tias qis qis. Lub sijhawm kaw yog 30% luv dua ib zaug - phaj li qub, txo cov dej siab siab rauj siab. Tsis tas li ntawd, kev ywj pheej sealing tsim ntawm ob lub discs ua rau muaj kev ntxhov siab ntau dua thiab hnav tsawg dua. Ua ke nrog ib qho nyuaj alloy sealing nto thiab lub caij nplooj ntoos hlav- pab qauv, qhov no ua rau lub neej ntev kev pab cuam, ua tau raws li qhov yuav tsum tau sealing txawm tias tom qab 500,000 qhib thiab kaw lub voj voog.

Cov lus sib piv: Ib Phaj vs. Dual Phaj Check Valve
| Sib piv Dimension | Ib Plate Check Valve (Wafer) | Dual Phaj Check Valve (Wafer) |
| Tus Qauv Tsim | Muaj ib lub voj voog ib ncig uas pivots eccentrically qhib. | Muaj ob daim hlau semicircular hinged rau ntawm tus pin hauv nruab nrab. |
| Txoj Cai Kev Ua Haujlwm | Media siab thawb lub phaj nkaus xwb qhib; cia siab rau lub ntiajteb txawj nqus los yog backpressure kaw. | Siab thawb cov phiaj qhib; feem ntaucaij nplooj ntoos hlav- pabrau qhov zoo kaw. |
| Flow Area | Loj. Muab txoj kev uas yuav luag tsis muaj kev cuam tshuam thaum qhib tag nrho. | Me me me. Lub hauv paus tus pin thiab kev txhawb nqa ncej nyob qee qhov chaw hauv txoj kev ntws. |
| Flow Resistance | Tsawg. Tsawg siab poob rau hauv txoj haujlwm qhib tag nrho. | Nruab nrab. Me ntsis siab dua ib phaj, tab sis superior rau cov tsoos nqa check li qub. |
| Dej rauj tswj | pluag. Kev mus ncig ntev thiab hnyav disc feem ntau ua rau nrov nrovslammingthiab hydraulic shocks. | Zoo heev. Caij nplooj ntoos hlav- pab kaw nrawm ua rau nws ua tau"Tsis yog-Slam"tsim, zoo suppressing dej rauj. |
| Installation Orientation | Feem ntauKab rov tav. Kev teeb tsa ntsug tsuas yog txwv rau sab saud nkaus xwb (feem ntau tsis ruaj khov). | Kab rov tav, ntsug, lossis inclined. Caij nplooj ntoos hlav-kev pab kaw ua rau nws muaj ntau yam. |
| Nyhav & Loj | Lub teeb yuag nrog ultra- lub ntsej muag luv - mus rau - ntsej muag (Wafer) qhov ntev. | Lub teeb heev & Compact. Feem ntau sib dua li ib lub phaj valve ntawm tib qhov loj. |
| Muaj Qhov Loj | Feem ntau siv rau DN 50 - DN600 (2" txog 24"). | Nyiam rauLoj Lojdaim ntawv thov (txog DN2000+ / 80"). |
| Sealing Performance | Nruab nrab. Cia siab rau ib qho - phaj nruab nrab; nquag hnav tsis sib xws thaum muaj kev kub ntxhov. | Zoo. Dual daim hlau muab kev sib npaug ntawm lub zog thiab kev sib cuag nrog lub rooj zaum. |
| Cracking siab | qis. | Me ntsis siab dua (yuav tsum kov yeej lub caij nplooj ntoos hlav nro). |
| nyuaj | Yooj yim. Tsawg qhov chaw, yooj yim khaws cia. | Siab dua. Muaj cov springs, washers, thiab precision pob khawm. |
| Nqi / Nqe Point | qis (rau me me mus rau nruab nrab diameters). | Siab dua (vim precision springs thiab dual{0}} phaj machining). |

FAQ
Dab tsi yog cov txiaj ntsig ntawm kev siv ob lub tshev valve?
Ob chav kos li qub ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv dej kev ncaj ncees hauv ntau daim ntawv thov. Cov valve no tshwj xeeb tsim los rautiv thaiv kev rov qab los thiab kev sib kis, kom ntseeg tau tias cov dej haus tsis muaj paug. Lawv txoj haujlwm txhim khu kev qha yog qhov tseem ceeb hauv kev tswj xyuas cov dej huv huv.
Koj yuav siv ib daim tshev valve qhov twg?
Altecnic ib leeg kos li qub yog siv los tiv thaiv kev pheej hmoo ntawm rov qab thiab rov qab siphonage paug hauvcov tsev nyob hauv tsev, pej xeem thiab cov tsev lag luam.
Dab tsi yog qhov lifespan ntawm ob daim tshev valve?
Nws yog ib qho tseem ceeb uas yuav tsum tau muaj cov khoom siv roj hmab tshiab txhua tsib xyoos lossis ntau xyoo, tab sis qhov seem ntawm ob - kuaj lub valve tuaj yeem siv sijhawm ntev heev, muaj peev xwm.tshaj 20 xyoo, nrog kev tu kom zoo. Tab sis tus tiv thaiv rov qab tuaj yeem xav tau kev kho ntxov lossis hloov pauv rau ntau yam, tshwj xeeb yog dej tsis zoo.
