Tung tung mi globe valve ku gate valve, icopo yero nenedi?

Wek wanyuth ango ma utiye tung tung ikum globe valve kuvalve mi dhugola.

01

Ayi

Ka kabedo mi ketho piny utiye nok, bed ma ling ikum lembe ma iyero:

Kuvalve mi dhugolaecopu geno rwom ma rwom pare tiye ikinde ni cego kama jugwoko iye piny, kara ebed ku adwogi maber mi pii ma wok kud i iye. Ka jube yabo man ju cego, valve core man sealing surface pa valve seat gibedo kare ku kare i cing gi man gi nyai ikumgi gigi, pi meno sealing surface bedo yot ni ketho, man kavalve mi dhugolautiye kago ku cego, tung tung mi tegu pa pii ikind kore ku ngeye pa pipeline utiye malac akeca, ma weko kabedo ma jukubo kudu doko tek.

Kite mavalve mi dhugolabibedo matek uloyu globe valve, ni nen, i lembe pa caliber marom, gate valve utiye malo uloyo globe valve, man globe valve utiye bor uloyuvalve mi dhugola. Mi medo,valve mi dhugolajupoko i dul ma ler man dul macol. Valve ma juku timo ngo.

Kite ma etiyo kudu

Ka globe valve oyabere man cego, etiye rising stem, niwacu, ka handwheel utur, handwheel bi loko man bi tingo ku stem. Kuvalve mi dhugolautiye ni loko cing cing ni weko valve stem timo tic mi tingo piny, man kabedo pa cing cing kende udong marom.

Kite ma pii mol kudu tung tung, kuvalves mi dhugolamitu yabu nyo cego, ento globe valves epe. Globe valve utiye ku yore moko ma jukwanu, manvalve mi dhugolaepe ku yore mi donjo man mi wok woko.

Mi medo,valve mi dhugolakende etiye ku lembe aryo: oyabere nyo cego, man kare mi yabo man cego pa gate plate utiye malac, man kare mi yabo man cego utiye malac. Movement stroke pa valve plate pa globe valve utiye nok, man valve plate pa globe valve copo cungu kama moku pi loko pii. Kuvalve mi dhugolaecopu tiyo kudu kende pi poko piny man epe ku tic mange.

Tung tung mi tic

Globe valve ecopu tiyo pi cut-off man pi loko pii. Peko pa globe valve utiye malac, man ebedo tek ni yabo man cego, ento pi bor pa valve plate ku sealing surface utiye nyanok, yabu man closing stroke utiye nyanok.

Pienvalve mi dhugolaecopu bedu ma oyabe man cego kende, ka eyabere, rwom pa pii ma mol i valve body channel utiye 0, ci yabo man cego pavalve mi dhugolabibedo ku tic ma lee, ento jamb dhugola utiye bor ku kama juketho i iye, man kare mi yabo man mi cego ubedo malac.

Kethu man kite ma wotho kudu

Adwogi pavalve mi dhugolayo ma pii mol kudu i yore ario zoo utiye acel, epe ku yeny pa yore mi donjo man yo ma wok kud i iye, man yore copo mol i yore ario zoo. Globe valve umitu juketh i yore ma juketho ku arrow pa kum valve, man cik moko nuti maleng ikum yore mi donjo man mi wok pa globe valve, man yore mi mol pa globe valve juyike nicaku malu ni piny nimakere ku "loko adek" pa valve pa China.

Valve mi juku piny utiye piny man malu woko, man kud woko utiye pipe maleng ma epe i rwom pa phase acel. Kuvalve mi dhugolayore mi mol utiye iwi laini ma lageng. Stroke pavalve mi dhugoladit uloyu pa globe valve.

Ku nen pa rwom pa mol, ka eyabere, rwom pa mol pa gate valve utiye nok, man rwom pa mol pa load stop valve utiye malac. Coefficient mi juku mol pa piny ma rwinyovalve mi dhugolautiye 0.08~0.12, tego mi yabo man mi cego utiye nok, man piny ma iye copo mol i yore aryo. Pek pa mol pa globe valves utiye wang 3-5 pavalves mi dhugola.Yabu man cego mitire ni cego pi nwangu sealing, spool pa globe valve cego zo ka etuc i sealing surface, ci wear pa sealing surface utiye nok akeca, pi rwom ma malu pa kero madit mi medu actuator pa globe valve umaku ibed ma ling ikum torque control mechanism adjustment mechanism.

Yore ario utiye mi ketho globe valve, acel utiye ni medium copo mondo kud ithe spool, berne utiye ni packing epe ku pressure ka valve cego, ma copo medo kwo pa packing, man ecopu loko packing ka pipeline ma ni in kore pa valve utiye i te pressure; Peko utiye nia tego pa valve utiye malac, ma romo wang 1 pa upper flow, axial force pa valve stem utiye malac, man valve stem yot ni guro.

Pieno, yore eni ber kende pi globe valves ma diameter migi nok (DN50 nyo ma piny), man globe valves ma malu pa DN200 tiyo ku piny ma mol kud malu. (Electric globe valves pol kare tiyo ku yore mi mondo kudi malu.) Peko pa yore mi mondo kudi malu utiye tung tung ku yore mi mondo kud piny.

Sealing

Kabedo ma juketho i iye globe valve utiye theng trapezoidal ma nok pa valve core (nen kite ma valve core utiye kudu), ka valve core upoto piny, eromo ku valve closing (ka tung tung mi pressure utiye malac, andha, closure epe, ento check effect epe marac),valve mi dhugolajugwoko ku thenge pa valve core gate plate, tic pa valve ne ber ungo calu globe valve, man valve core copo podho ngo calu globe valve ma rom ku valve closing.
