Clamp Txuas: Ib daim ntawv sib txuas uas clamps lub valve thiab ob xaus ntawm cov yeeb nkab ua ke nrog bolts.
Threaded Kev sib txuas:
Feem ntau siv rau cov npoo me me, nws yog txoj kev txuas yooj yim.
Muaj ob qho xwm txheej:
1. Ncaj Nraim: Siv cov xov sab hauv thiab sab nraud kom ncaj qha txuas cov nyhuv sib khi. Txhawm rau kom ntseeg tau tias kev sib txuas tsis xau, cov roj txhuas, hemp thiab polytetrafluoroethylene nyoos cov kab xev feem ntau yog siv rau txhaws; Polytetrafluoroethylene nyoos daim kab xev yog nce dav siv. Cov khoom siv no muaj cov nyhuv sib khi tau zoo heev thiab kev ua haujlwm zoo corrosion. Nws yooj yim dua rau kev siv thiab khaws cia. Thaum disassembling, nws tuaj yeem raug tshem tawm kiag li vim tias nws yog tus tsis nplaum ua yeeb yaj kiab, uas yog qhov zoo dua li cov roj txhuas thiab hemp.
2. Kev tuav ncaj qha: lub zog ntawm zawm ntawm cov xov yog kis tau rau lub gasket ntawm ob lub dav hlau, cia lub gasket mus ua lub luag haujlwm sib khi.
Flange kev twb kev txuas: Qhov feem ntau siv daim ntawv sib txuas hauv li qub.
According to the shape of the joint surface, it can be divided into the following types: 1. Concave and convex type: The working pressure is high, and medium-hard gaskets can be used 2. Trapezoidal groove type: used for valves with a working pressure of>=64 kg/cm2, or high-temperature valves. Siv cov hlau me me hlau ua pa roj av . 3. tus nplaig nplaig thiab zawj hom hauv cov xov xwm corrosive, nrog rau cov nyhuv zoo. Gaskets nrog cov khoom siv yas loj dua tuaj yeem siv, siv rau cov roj hmab uas yooj yim: siv rau cov khoom siv flooter tshiab: siv rau cov kev ua haujlwm tshiab2Cov. Lub gasket yog lo ntsiab muag zoo nkauj thiab ua los ntawm cov hlau.
Ferrule kev txuas: Ferrule kev sib txuas daim ntawv, uas tau saws hauv cov cheeb tsam uas muaj valve khoom hauv Suav teb.
Nws cov kev sib txuas thiab cov cai khi yog: thaum cov txiv ntoo tau nruj, yog li ntawd nws cov hniav rov qab nrog lub cev sab hauv lub cev, yog li nws tuaj yeem tiv thaiv kev to taub. Qhov zoo ntawm daim ntawv sib txuas no yog: 1. Nws yog ib qho yooj yim rau nruab ntawm qhov siab . 1. kev ua precision qis; 2. Me me, lub teeb yuag, cov qauv yooj yim, yooj yim rau disassemble thiab sib sau ua ke; 3. Muaj ntau yam ntaub ntawv tuaj yeem xaiv, haum rau kev tiv thaiv corrosion; 4. Lub zog kev sib txuas, tuaj yeem tiv thaiv siab (1000 kg / cm / CM2), kub siab (650 degree) thiab cuam tshuam kev ntsuas
Taub qab vuam txuas: txoj kev sib txuas uas ncaj qha rau Welds lub pob valve thiab xa cov raj xa dej ua ke.
Sab hauv kev sib txuas ntawm tus kheej: qhov no yog daim ntawv sib txuas uas siv nruab nrab siab rau kev zawm hniav rau tus kheej. Nws lub nplhaib sib khi tau ntsia nyob rau sab hauv lub khob hliav qab, sib sau ib lub kaum sab xis nrog ib sab ntsib qhov nruab nrab. Qhov nruab nrab siab yog kis tau rau sab hauv lub khob hliav thiab tom qab ntawd rau lub nplhaib sib khi. Ntawm lub khob hliav qab saum npoo ntawm ib qho lub kaum sab xis, ob lub zog sib xyaw ua ke, ib qho yog sib npaug ntawm txoj kab nruab nrab thiab sab nraud yog nias ntawm phab ntsa sab hauv ntawm lub cev hauv lub cev. Qhov kawg ntawm kev sib zog tiv thaiv yog tus kheej nruj zog quab yuam. Qhov ntau dua qhov nruab nrab siab nruab nrab, ntau dua tus kheej-zawm quab yuam quab yuam. Yog li ntawd, daim ntawv sib txuas no yog qhov haum rau cov kev ntsuas siab li qub. Nws txuag tau ntau cov ntaub ntawv thiab Manpower piv rau Flange kev sib txuas, thiab tsuas yog siv qee qhov kev ntseeg tau ua ntej kom nws muaj peev xwm tso tau thaum lub siab nyob hauv lub valve tsis yog siab. Li qub tau ua rau siv tus kheej-zawm cov hauv paus ntsiab lus yog feem ntau cov kev ntsuas siab.
Clamp Txuas: Haum rau cov khoom siv qis uas nquag disassembled. Nws tsuas yog xav tau ob lub bolts los nruab nws, uas yog txoj kev sib txuas sai.
Muaj ntau hom kev sib txuas ntawm valve, xws li qee qhov me me uas tsis tas yuav raug muab tshem tawm yog welded rau yeeb nkab; Qee qhov tsis yog xim hlau siv siv kev sib txuas, thiab lwm yam. Yuav tsum kho lawv raws li cov xwm txheej tshwj xeeb.
Lwm Cov Khoom Siv
Muaj li qub thiab cov yeeb nkab fittings, uas yog siv nyob rau hauv kev sib txuas pipeline lossis tswj cov tshuab. Li qub thiab cov yeeb nkab fittings tsis tuaj yeem muaj nyob ntawm nws tus kheej, tab sis txuam nrog sib. Li qub thiab cov yeeb nkab fittings yog ua los ntawm cov hlau thiab hlau steel thiab stainless hlau, raws li zoo li pvc lossis lwm yam ntaub ntawv. Nyob rau hauv xyoo tsis ntev los no, nrog kev txhim kho ntawm tib neeg cov txheej txheem muaj nyob, qhov kev thov rau cov khoom noj uas tsis yog nce ntxiv. Yog li ntawd, nws tau ua rau txoj kev loj hlob ntawm cov zaub mov txias, yog li cov stainless hlau huv lub valve thiab cov yeeb nkab fittings thiab cov nrov dua.
