Peko ma rwinyo man yore mi gengu pa butterfly valves man gate valves

Valve mediri ku gwoko man timo tic ma jumiyo i kare moko mi tic, man tic mi gwoko wel pa parameter ma jumiyo i kind kare ma juketho julwongo ni failure-free. Ka tic pa valve utur, ebi bedu A malfunction bi timere.

1. Pong pa sanduku

Eni ubedo thenge madit mi ngwec, ringo, pii, man pii, man pol kare juneno i factory.

The lembe ma nyayu pii ma wok kud i sanduku mi pong piny utiye ma e:

①Jam piny ne epe ku kero pa lyethu, lyethu man tegu pa piny ma jutiyo kudu;

②Yore mi pongu piny epe, asaga ka juketho piny ceke i spiral, ecopu nyayu pii ma mol;

③Kite ma tic ku cuma nyo rwom pa valve stem epe, nyo ovality utiye, nyo nicks utiye;

④Valve stem ubedo ku vur, nyo rusted pi bedo ma epe ku gwok i polo;

⑤The valve stem is bent;

⑥Packing ne jutiyo kudu pi kare malac man dong uti;

⑦Operation ne tek mandha.

Yore mi jwigo pii ma wok kud i packing utiye:

① Yer pa fillers maber;

②Pong i yo maber;

Ka valve stem epe, umitu juyike nyo julok, man rwom pare umaku obed ▽5, man ma pire tek uloyu, umaku ubed ▽8 nyo malu, man epe ku peko mange;

④ Tim yore mi gwoko kwo peri pi jwigo nyai, man ma nyai umitu julok;

⑤Bending pa valve stem umaku juyik nyo judwoko manyen;

⑥I ngei ma jutiyo kudu pi kare moko, umitu julok;

⑦Tic ucikere ni bedu maber, yabo moth man cego moth pi jwigo aloka loka pa lyethu nyoke ret ma nyai.

2. Cwalo pa piny ma cego

Pol kare, pii ma wok kud i sanduku mi pong piny julwonge niya pii ma woko, man thenge ma cego julwonge niya pii ma iye. Cwalo pa piny ma juku, i kind valve, epe yot ni nwangu.

Lwiny pa piny ma juketho i iye jupoko i dul aryo: acel ubedo pii pa piny ma juketho i iye, man mukende ubedo pii pa theng cing.

Lembe ma nyayu pii ma mol utiye:

①Kabedo ma juketho i iye piny epe maber;

②The sealing ring ok rwate maber ku valve seat man valve disc;

③Kit ma valve disc ku valve stem utiye kudu epe;

④The valve stem is bent and twisted, kara ma malu man ma piny ma juketho i iye kud ubed ikindgi;

⑤Cwiri pio pio, kabedo ma juketho i iye epe maber nyo dong unyothere pi kare malac;

⑥ yero piny maber ongo, ecopu ciro ngo lyethu pa piny;

Ti ku globe valve man gate valve calu regulating valve. Kabedo ma juketho i iye piny copo ciro ngo nyai pa piny ma mol pio pio;

⑧Jam moko bibedo ngic moth moth ingey valve cego, kara kabedo ma juketho i iye bi nen ni slits, man erosion de bi timere;

⑨Threaded connection jutiyu kudu ikind piny moko ma jukubo ku valve seat man valve disc, ma yot ni kelo tung tung pa oxygen concentration battery man corrode loose;

⑩Valve copo bedu ngo maber pi bedo pa piny ma reco calo welding slag, rust, dust, nyo piny moko ma tiyo ku cuma i yub mi yubu piny ma podho piny man juku valve core.

Lembe mi gengu two utiye:

①Mapodi itiyo kudu, umitu ipim pressure man leak maber, man inwang leakage mi thenge mi sealing nyo the root of sealing ring, man ingeye iti kude ingey timo tic;

②Umitere ni neno con ka dul matung tung pa valve utiye maber. Kud iti ku valve ma valve stem utur nyo utur nyo valve disc ku valve stem gi makore ngo maber;

③Valve ucikere ni cego matek, ungo ku tego. Ka inwango nya rwom pa piny ma juketho i iye piny eca ber ongo nyo piny moko utiye ma ucungo, umitu iyabe pio pio pi kare manok kara piny ma jucwalo uwok woko, man ijuke maber;

④Ka ibe yero valve, ungo kende kende kero pa valve, ento bende kero pa piny ma juketho i iye umitu ipar;

Nimakere ku kit pa valve man tic kudu maber, piny ma mitere ni dwoko rwom pa pii ucikere ni tiyo ku regulating valve;

⑥Pi lembe ma medium ubedo ma ngic man tung tung mi lyethu ubedo malac ingey cego valve, valve umaku ju cego matek ingey cego;

7Ka kom pa valve, valve disc man sealing ring gicokiri ku thread, PTFE tape copo bedu calu packing ikind thread, kara kud ubed ku gap;

⑧Filter ucikere ni medu in kore pa valve pi valve ma copo podho i lum.

3. Valve stem lift failure

The lembe ma nyayu ret pa valve stem utiye:

①Thread ne unyothere pi tic ma lee;

② bedo mbe pa moo nyo moo ma rwinyo;

③The valve stem is bent and twisted;

④Ajiki pa wi ngom epe;

⑤ Fit tolerance utiye marac, man bite utiye matek akeca;

⑥The valve stem nut is inclined;

⑦ Yero piny ma ber ongo, calu, valve stem man valve stem nut juyike ku piny acel, ma yot ni camu;

⑧Thread ubedo corroded ku medium (ma nyutho valve ku stem valve macol nyo valve ku stem nut piny);

⑨Valve ma wok iwi yamu epe ku gwok, man valve stem thread upong ku buru man lum, nyo unyai ku koth, ngico, ngico man pee.

Yore mi gengu:

① Tic maber, kud iket tek ka ibe cego, kud i tuc i thenge ma malu ka ibe yabo, lok handwheel wang acel nyo aryo ingey yabo ma romo ketho thenge ma malu pa thread cego, kara kud ijuk piny ma i iye ni cwalu valve stem malu ni turo;

②Nen kite ma moo tiyo kudu kare ku kare man bed ku moo maber;

③Kud iyab man cego valve ku lever mabor. Jurutic ma gingeyo tic ku lever ma nok umaku gi gwok kero migi maber pi gwoko valve stem (ma nyutho valve ma ucungo iwi handwheel man valve stem);

④Medu ber pa tic nyoke yiko piny ni rombu ku lembe ma jukwanu;

⑤Jam tic ucikere ni bedu ma tek man ma rwinyo ku lyethu pa tic man lembe mukende mi tic;

⑥Nut pa valve stem ucikere ngo ni bedu ku piny marom ku valve stem;

Ka itiyo ku plastik calu valve stem nut, tego ucikere ni nen, ungo kende kende bedo maber pa corrosion man friction coefficient ma nok, ento bende peko pa tego, ka tego epe, kud iti kudu;

⑧Gam ma gwoko valve stem umaku juketh i valve ma yamo wok;

⑨Pi valve ma oyabere, lok handwheel kare ku kare mi juku valve stem kud ucwir.

4. Mukende

Gasket leakage:

The lembe madit utiye nia ecopo ngo ni rwinyo man ecopo ngo ni rwinyo ku lyethu man tegu pa tic; man aloka loka pa lyethu pa valve mi lyethu ma malu.

Ti ku gaskets maber pi tic. Nen ka piny ma jutiyo kudu pi gasket ber pi valve manyen. Ka epe, umitu julok. Pi valve ma lyethu tek, jwigo bolts kendu ikare ma itiyo kudu.

Kum valve ma otur:

Pol kare piny ma wok kud i ngico. Ka piny ngic, valve umaku obed ku jam gwoko lyethu man yore mi lubo lyethu. Ka epe, pii ma ni i valve man pipeline ma rwate kudu umaku juwodh woko ingey juku tic (ka plug utiye piny pa valve, plug ne jucopo yabu pi woth).

Handwheel ma unyothere:

Ma nyayu ret nyoke tic matek pa lever mabor. Ecopu bedu maber tek jara tic man dhanu mukende ma gitiye ku peko gi bedo moth.

Gland pa packing utur:

Teko ma rom ungo ka jube diyo piny, nyo gland ma rac (ma pol kare cast iron). Dii packing, lok screw marom, man kud idok piny. Ka ibe yubu piny, umitu kud iket cwinyi ikum piny madongo man ma pire tek kende, ento iketh cwinyi ikum piny ma pire tek calu gland, tek epe ebi nyayu peko i tic.

Ribu pa valve stem ku valve plate uthum:

Gate valve tiyo ku yore madwong mi rwate ikind wi valve ma nen calu T-shaped pa gate, man T-shaped groove saa moko jutiyu kudu ngo, pi meno wi rectangular pa valve stem rwinyo pio pio. Mandha ne kud i thenge mi yubu piny. Ento, jatic copo timo T-shaped groove mi weko ebed mayom.

Dhugola pa double gate valve copo diyo ngo dhugola matek:

Peko pa dhugola ario eca wok kud i wi wedge. Pi valve moko mi dhugola, wi wedge ma malu utiye ku piny ma ber ongo (cast iron ma rwom pare piny), man ebitur nyo etur ndhundhu ingey tic kudu. Wedge ma malu ubedo piny ma nok, man piny ma jutiyo kudu epe. Ngati ma tiyo kudu copo yike ku carbon steel man elok cast iron macon.
