Cov txheej txheem teeb tsa ntawm cov tshev valve yog dab tsi?

Txoj kev teeb tsa ntawm lub valve feem ntau yog txiav txim siab raws li hom valve, cov kev cai tshwj xeeb ntawm cov kav dej, thiab qhov chaw teeb tsa. Hauv qab no yog ntau txoj kev teeb tsa valve:

Ua ntej, kev teeb tsa kab rov tav

1. Cov kev cai dav dav: Feem ntau cov qhov ntsuas qhov (check valves), xws li cov qhov ntsuas qhov (swing check valves) thiab cov qhov ntsuas qhov (pipe check valves), feem ntau yuav tsum tau teeb tsa kab rov tav. Thaum teeb tsa, xyuas kom meej tias lub valve disc nyob saum cov yeeb nkab kom lub valve disc tuaj yeem qhib tau zoo thaum cov kua dej ntws mus tom ntej, thiab lub valve disc tuaj yeem kaw tau sai thaum cov dej ntws rov qab.

2. Cov kauj ruam teeb tsa:

Ua ntej kev teeb tsa, xyuas seb qhov tsos thiab sab hauv ntawm lub valve puas zoo thiab xyuas kom meej tias lub disc tuaj yeem qhib thiab kaw tau yooj yim.

Ntxuav cov khoom tsis huv thiab cov av sab hauv thiab sab nraud ntawm lub yeeb nkab kom ntseeg tau tias qhov kev ua haujlwm sealing thiab lub neej ua haujlwm ntawm lub valve.

Muab lub qhov ntsuas cua tso rau hauv qhov chaw teeb tsa uas tau teem tseg thiab siv cov cuab yeej xws li lub wrench los khi nws. Siv cov sealant kom raug rau ntawm lub nplhaib sib khi kom ntseeg tau tias kev ua haujlwm ntawm kev sib khi.

Tig rau ntawm qhov chaw kua dej thiab xyuas seb qhov xwm txheej ua haujlwm ntawm lub qhov ntsuas valve puas ua haujlwm kom ntseeg tau tias lub disc tau qhib thiab kaw kom raug.

Qhov thib ob, kev teeb tsa ntsug

1. Hom kev siv: Qee cov khoom siv kuaj xyuas tshwj xeeb uas tsim los, xws li cov khoom siv kuaj xyuas nqa, yuav xav tau kev teeb tsa ntsug. Lub disc ntawm hom khoom siv kuaj xyuas no feem ntau txav mus rau saum thiab nqis ntawm lub axis, yog li kev teeb tsa ntsug ua kom ntseeg tau tias lub disc txav mus los zoo.

2. Cov kauj ruam teeb tsa:

Nws tseem yog qhov tsim nyog los xyuas qhov tsos thiab sab hauv ntawm lub valve ua ntej kev teeb tsa.

Tom qab ntxuav cov yeeb nkab tas, muab lub qhov ntsuas cua tso rau hauv cov yeeb nkab thiab siv cov cuab yeej tsim nyog los kho nws.

Xyuas kom tseeb tias cov kua nkag thiab tawm yog qhov tseeb kom tsis txhob muaj kev nyem lossis kev puas tsuaj rau lub disc.

Qhov thib peb, cov txheej txheem teeb tsa tshwj xeeb

1. Clamp check valve: Lub check valve no feem ntau yog ntsia nruab nrab ntawm ob lub flanges, tsim rau cov sijhawm uas xav tau kev teeb tsa sai thiab kev rhuav tshem. Thaum teeb tsa, nws yuav tsum nco ntsoov tias qhov kev taw qhia ntawm clamp check valve hla mus yog sib xws nrog qhov kev taw qhia ntawm cov kua dej, thiab xyuas kom meej tias nws ruaj khov ntsia rau ntawm cov kav dej.

2. Kev teeb tsa vuam: Qee zaum, xws li cov kav dej siab lossis kub siab, tej zaum yuav tsum tau vuam lub qhov valve rau lub yeeb nkab. Kev teeb tsa no xav tau cov txheej txheem vuam nruj thiab kev tswj xyuas zoo kom ntseeg tau tias qhov nruj thiab kev nyab xeeb ntawm lub qhov valve.

Qhov thib plaub, kev ceev faj txog kev teeb tsa

1. Kev Taw Qhia: Thaum txhim kho lub qhov ntsuas valve, xyuas kom meej tias qhov kev taw qhia qhib ntawm lub disc valve yog sib xws nrog cov kev taw qhia ntws ib txwm ntawm cov kua dej. Yog tias qhov kev taw qhia teeb tsa tsis raug, lub qhov ntsuas valve yuav tsis ua haujlwm zoo.

2. Kev Ruaj Khoov: Yuav tsum xyuas kom meej tias lub valve kaw ruaj khov thaum lub sijhawm teeb tsa. Rau cov valve uas xav tau cov sealant lossis gaskets, teeb tsa raws li cov lus qhia los ntawm cov chaw tsim khoom.

3. Qhov chaw txij nkawm: Thaum txhim kho lub qhov ntsuas cua, yuav tsum xav txog qhov xav tau kev txij nkawm thiab kev kho dua tshiab yav tom ntej. Tseg qhov chaw txaus rau lub qhov rov qab kom nws yooj yim tshem tawm thiab hloov pauv yog tias xav tau.

Thib tsib, xyuas thiab sim tom qab kev teeb tsa

Tom qab kev teeb tsa, cov khoom siv kuaj xyuas yuav tsum tau kuaj xyuas thiab sim tag nrho kom paub tseeb tias lawv tuaj yeem ua haujlwm tau zoo. Koj tuaj yeem ua haujlwm ntawm lub disc ntawm lub valve kuaj xyuas kom paub tseeb tias nws tuaj yeem qhib thiab kaw tau yooj yim. Tib lub sijhawm, qhib qhov chaw kua dej, saib xyuas lub xeev ua haujlwm ntawm lub valve kuaj xyuas nyob rau hauv qhov kev ua ntawm cov kua dej, thiab xyuas kom meej tias lub valve disc tuaj yeem qhib thiab kaw tau zoo.

Hauv kev xaus, txoj kev teeb tsa ntawm lub valve yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb, suav nrog hom valve, qhov yuav tsum tau ua ntawm cov kav dej, thiab qhov chaw teeb tsa. Thaum lub sijhawm teeb tsa, cov lus qhia ntawm cov chaw tsim khoom thiab cov lus qhia txog kev teeb tsa yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias kev ua haujlwm ib txwm thiab kev siv lub valve mus sij hawm ntev.
