Peko ma pol kare time ki yoo me gengo ne i kom butterfly valves ki gate valves

Gin ma ki lwongo ni valve ni mede ki gwoko ki tyeko jami ma mite i kare me tic mo, ki tic me gwoko wel ma kimiyo i kin kare ma ki moko ni ki lwongo ni failure-free. Ka tic pa valve ni obale, obi bedo ni tic marac obi time.

1. Bok ma opong ki pii

Man aye gin ma pire tek ma mako ngwec, ngwec, mol, ki mol, ki pol kare ki neno i factori.

Gin ma oweko pii ni okati ki i bok ma ki keto iye jami ni tye kit man:

Jami ma ki tiyo kwede ni pe rwate ki rwom me lyeto, lyeto ki teko pa gin ma ki tiyo kwede;

②Yoo me pongo ni pi tye kakare, tutwale ka ki keto gin ni weny i yoo ma ki lwongo ni spiral, twero kelo pii ma mol;

③Kit ma ki tiyo kwede ki jami ma ki lwongo ni valve stem ni pe romo, onyo tye ki ovality, onyo tye nicks;

Gin ma ki lwongo ni valve stem ni tye ki buru, onyo obale pien pe ki gwoko ne i yamo ma oyabe;

⑤Gin ma ki lwongo ni valve ni tye ma otur;

Gin ma ki keto i bok ni dong ki tiyo kwede pi kare malac ki dong oti woko;

Tic ni tye ki gero madwong.

Yo me kwanyo pii ma mol ki i packing tye:

Yero maber pa jami ma ki keto iye;

②Pong i yoo ma opore;

Ka dul kom ma ki lwongo ni valve stem ni pe opore, omyera ki yub onyo ki lok, ki rwom me kome omyera obed maromo ▽5, ki ma piire tek loyo, omyera obed ▽8 onyo ma kato, ki pe tye peko mo keken;

Kwany yoo me gwoke me gengo buru, ki ma dong obale omyera ki lok gii;

⑤Bending pa valve stem omyera ki lok onyo ki lok manyen;

⑥I nge tic ki jami ma ki keto i bok ni pi kare mo, omyera ki lok;

⑦Tic ni omyera obed ma ocung matek, oyabe mot mot ki umu mot mot me gengo alokaloka me lyeto oyoto onyo peko ma tye i kin piny.

2. Cwer pa jami ma ki juku

Pol kare, pii ma aa ki i bok ma ki keto iye jami ni ki lwongo ni pii ma aa ki woko, ki dul ma ki juku ki lwongo ni pii ma aa ki iye. Cwer pa jami ma ki umu, i kin valve, pe yot me nongo ne.

Cwer pa jami ma ki umu ni ki poko ne i dul aryo: acel obedo cwer pa gin ma ki umu kwede, ki mukene obedo cwer pa tyen gin ma ki umu iye.

Gin ma kelo pii ma mol tye:

①Ka ma ki umu iye jami ni pe ki buru maber;

Gin ma ki lwongo ni sealing ring ni pe rwate ki valve seat ki valve disc;

Kubbe ma tye i kin valve disc ki valve stem pe tek;

Gin ma ki lwongo ni valve stem ni ki guro ki ki guro, wek dul ma malo ki piny ma ki juku ni pe obed i kin gii;

Cwalo oyotoyot tutwal, kama ki umu iye ni pe tye maber onyo dong obale pi kare malac;

6 yero jami ma pi opore, pe twero diyo cwiny i kom jami ma tye i kin piny;

Tii ki globe valve ki gate valve ma calo regulating valve. Kabedo ma ki umu iye ni pe twero diyo peko me pii ma mol oyotoyot;

⑧Jami mogo obi doko ngiic mot mot ingee ki umu valve ni, wek kama ki umu iye ni obi nen ma obale, ki buru bene obi time;

⑨Threaded connection ki tiyo kwede i kin jami mogo ma ki umu ki valve seat ki valve disc, ma yot me kelo apoka poka i kom oxygen concentration battery ki corrode loose;

⑩Valve ni pe kitwero umu matek pien tye iye jami ma calo jami ma ki lwongo ni welding slag, rust, dust, onyo jami ma ki tiyo kwede i yub me yubu jami ma poto piny ki gengo valve core.

Yoo me gengo two ni tye:

①Mapwod pi itiyo kwede, omyera i temo rwom me teko ki pii ma mol, ki nong pii ma mol ki i kom gin ma ki umu kwede onyo i kom gin ma ki umu kwede, ki ingeye iti kwede inge tic kwede;

②Mitte me neno con ka dul ma pat pat me valve ni tye maber. Pe iti ki valve ma valve stem ni tye ma otur onyo ma otur onyo valve disc ki valve stem ni pe gikubbe maber;

③Valve omyera ki umu matek, ento pi tek tek. Ka inongo ni rwate i kin jami ma ki umu ni pe ber onyo tye gin mo ma gengo, omyera i oyabe cut cut pi kare manok wek jami ma obale ni okati woko, ki dong i umu ne maber;

④Ka itye ka yero valve, pi tek pa kom valve keken, ento bene tek pa jami ma ki umu omyera ki tam iye;

Malube ki kit ma ki yubu kwede valve ki tic kwede maber, jami ma mite me loko mol omyera oti ki valve ma loyo;

⑥Pi kare ma piny ni ngiic ki apoka poka me lyeto dit inge cego valve, valve omyera ki umu matek inge juku ne;

7Ka kom pa valve, valve disc ki sealing ring gikubbe ki thread, PTFE tape ki tiyo kwede me keto i kin thread ni, wek pe obed ki apoka poka;

8Myero ki med filter i nyim valve pi valve ma twero poto i pii.

3. Peko me tingo gin ma ki lwongo ni valve

Gin ma oweko valve stem lifting ni pe tiyo maber tye:

Gin ma ki lwongo ni thread ni obale pi tic ma okato kare;

peke pa moo onyo moo ma obale;

③Gin ma ki lwongo ni valve ni tye ma otur ki owire;

④Gin ma ki keto i kom piny ni pe romo;

Kit ma ki diyo kwede pe tye kakare, ki ka ma ki camo ni tek tutwal;

⑥Nut ma ki lwongo ni valve stem ni tye ma ocung;

Yero jami ma pi opore, me labolle, gin ma ki lwongo ni valve stem ki valve stem nut ni ki yubu ki jami acel, ma yot me camo;

Gin ma ki lwongo ni thread ni obale ki gin ma tye i kin gii (ma nyutu valve ma tye ki dark stem valve onyo valve ma tye ki stem nut piny);

⑨Valve ma tye ki yamo ma oyabe ni pe ki gwok, ki gin ma ki lwongo ni valve stem thread ni ki umu ki buru ki kweyo, onyo ki buru ki kot, ngiico, ngiico ki pee.

Yoo me gengo:

① Tic maber, pi i dii ka itye ka cego, pi i oo i kom gin ma ki lwongo ni dead center ma malo ka itye ka yabo, lok cing tyen acel onyo aryo inge yabo ma romo weko dul ma malo pa gin ma ki lwongo ni thread ni umu, wek pe ki diyo gin ma ki lwongo ni valve stem malo me rwate;

②Nen kit ma moo tye kwede kare ki kare ki gwoko kit ma moo ni tye kwede;

③Kur iyab ki umu gin ma ki lwongo ni valve ki gin ma ki lwongo ni lever mabor. Lutic ma gi ngeyo tic ki gin ma ki lwongo ni lever ma cok omyera gu gwok teko ma mite me gengo tur pa valve stem (ma nyutu ni valve ma ki kubbe ki handwheel ki valve stem);

Medo rwom me tic onyo yubu me rwate ki gin ma mite;

Jami ni omyera obed ma tek ki balo ki rwate ki rwom me lyeto me tic ki jami mukene me tic;

Gin ma ki lwongo ni valve stem nut omyera pe ki yub ki gin acel ki valve stem;

Ka itye ka tic ki jami ma ki yubu ki plastik calo gin ma ki lwongo ni valve stem nut, teko ne omyera ki nen, pi teko ne maber keken ki teko ne manok, ento bene peko me teko ne, ka teko ne pe romo, pi iti kwede;

⑧Gin ma gwoko kom valve omyera ki med i kom valve ma tye ki yamo ma oyabe;

⑨Pi valve ma oyabe maber, lok cinge kare ki kare me gengo valve stem ni pe obale.

4. Mukene

Gasket leakage:

Gin ma pire tek tye ni en pe tek i kom buru ki pe rwate ki rwom me lyeto ki rwom me tic; ki alokaloka me lyeto pa valve me lyeto ma malo.

Tii ki gaskets ma rwate ki kit me tic. Nen ka jami ma ki tiyo kwede me gasket ni ber pi valve manyen. Ka pe opore, omyera ki lok ne. Pi valve ma tye ki lyeto ma malo, juku bolt ni i kare me tic kwede.

Kom valve ma otur:

Pol kare bino pi ngiico. Ka piny ngiic, gin ma ki lwongo ni valve ni omyera obed ki gin ma gengo lyeto ki jami ma gengo lyeto. Ka kumeno ku, pii ma tye i valve ki pipeline ma kubu omyera ki kwany woko inge juku tic (ka tye gin ma ki keto i te valve, ki twero yabo gin ni me kato woko).

Gin ma ki lwongo ni handwheel ma obale:

Okelo pi turo onyo tic matek pa gin ma ki lwongo ni long lever. Ki twero gengo ne ka ngat ma tye ka tic kwede ki dano mukene ma tye ki miti ni gu keto cwiny gi iye.

Gin ma ki lwongo ni packing gland ni otur:

Teko ma pe rom ka ki diyo jami, onyo gland ma obale (pol kare ki yubu ki nyonyo). Dii gin ma ki keto ni, lok gin ma ki lwongo ni screw ni ma rwate, ki pi i lok. Ka itye ka yubu jami, pi myero iket cwinyi i kom jami ma dit ki ma pire tek keken, ento bene iket cwinyi i kom jami mukene ma calo gland, ka kumeno obi balo tic kwede.

Kubbe ma tye i kin gin ma ki lwongo ni valve stem ki valve plate ni obale woko:

Gin ma ki lwongo ni gate valve ni tiyo ki yoo mapol me kubbe i kin wic ma ki lwongo ni rectangular me valve stem ki T-shaped groove pa gate, ki T-shaped groove ni pol kare pe ki tiyo kwede, ki dong rectangular head pa valve stem ni rweny oyotoyot. Ma loyo ki i dul ma yubu jami me cobo peko. Ento, latic twero yubu dul ma nen calo T me miyo bedo ki rwom ma lapiny.

Doggola me doggola aryo ni pe twero diyo umu ne matek:

Teko pa doggola aryo ni ki kelo ki i kom dul ma malo ni. Pi jami mogo ma ki lwongo ni gate valves, dul ma malo ni ki yubu ki jami ma pe ber (ma ki yubu ki nyonyo ma rwom ne lapiny), ki obi rweny onyo tur cut cut ingee tic kwede. Gin ma ki lwongo ni wedge ma malo ni tye gin matidi, ki jami ma ki tiyo kwede ni pe dwong. Ngat ma tiyo kwede twero yubu ne ki nyonyo ma ki lwongo ni carbon steel ki loko nyonyo macon ni.
