Cov wafer-hom pob pob valve yog lub valve lub valve ntsia nruab nrab ntawm ob qho fleel flanges los ntawm kev siv cov pob tw. Lub pob rotates 90 degrees kom ua tiav nruab nrab ntawm-tawm tswj. Nws cov qauv tsim thiab cov ntawv thov muaj raws li hauv qab no:
1. Cov qauv thiab cov ntsiab cai ua haujlwm
Txoj kev sib txuas
Lub cev lub cev tsis muaj qhov flange thiab clamped ntawm cov yeeb nkab flanges los ntawm kev siv cov pob tw. Cov txheej txheem ntev yog 30% -70% luv dua li tias flange hom pob valve, thiab qhov hnyav yog txo los ntawm 40% -60%.
Kev Siv Hluav Taws Xob
Ncig lossis v-puab los ntawm lub qhov yog qhib hauv nruab nrab ntawm pob. Lub pob valve tau tsav kom tig 90 degrees thiaj li uas lub qhov los ntawm cov raj xa dej (qhib) lossis ntsug (kaw).
Sealing Tsim
Cov khoom lag luam muag cov hom siv PTFE lossis siv cov khoom siv hluav taws xob muaj zog yog welded yog welded nrog nyuaj alloy, ua ke nrog kev ua tiav lub caij nplooj ntoo hlav kom ua tiav ob tog xoom.
Ob chav qauv eccentric txo cov kev sib txhuam tsis yog lub rooj zaum thiab txhim kho lub neej sib khi.
2. Kev faib tawm thiab cov yam ntxwv
Raws li daim ntawv sealing
Cov Hom Mos Ntse: Siv Kub -20 Qib ~ 180 Degree, nruab nrab suav nrog dej, chav, thiab qaug zog kua.
Hard type: qhov kub ua kom nce mus txog 300 degree, haum rau cov viscous media muaj cov lus lossis cov fibers.
Raws li tsav hom phau ntawv hom: Torque me, nruab nrog kov lossis gearbox.
Pneumatic / Electric Hom: Kev sib koom tes ua hauj lwm, tuaj yeem paub tsis siv neeg kho thiab chaw taws teeb.
Cov Qauv Tshwj Xeeb Ultra-Luv Hom: Tus qauv sib tw ntev, haum rau kev teeb tsa kev teeb tsa nrog qee qhov chaw tsawg.
Txuas v-hom pob valve: lub pob los ntawm lub qhov yog v-puab, nrog tawm kev cai ntws kev ua haujlwm.
3. Kev ua haujlwm tsis tau
| Tus yam ntxwv | Parameter ntau / piav qhia |
|---|---|
| Nominal siab | PD1.0 ~ 2.5MPA (Chav Kawm Class150) |
| Siv tau kub | -29℃~ 300℃(nyob ntawm cov khoom sealing) |
| Muaj Feem Loo | Dej, roj, roj nkev, kua qaub thiab alkali daws, fiber ntau slurry, thiab lwm yam. |
| Kev ua kom theem | Ansi B16.104 Cov Kawm VI (xoom |
4. Daim ntawv thov teb
Kev Lag Luam thiab Kev Lag Luam: LNG Tsheb Thauj Mus Los, Kev Lag Luam Txuas Pipeline Txiav, Reactor Mag Zog Kev Tswj.
Muaj Automation: Mill Pulp Flunion cov cai, zaub mov noj tswj kev tu vaj tse.
Kev tiv thaiv ib puag ncig cov khoom: Dej phwj tuaj kho mob, khib roj rov qab ntaus ntawv.
5. Xaiv cov ntsiab lus
Media compatibility: stainless hlau valve lub cev + hastelloy foob yog qhov yuav tsum muaj rau cov corrosive.
Qhov chaw teeb tsa: Ultra-Luv los yog nyias tsim qauv yog cov chaw nyob hauv nqaim.
Kev ua haujlwm ntau: Hnav-resistant hlau foob yuav tsum tau teeb tsa rau high-zaus qhib thiab kaw cov scenarios.
