3. Ball Valve
Ball valve ucaku kud i plug valve. Thenge pare mi yabo man mi cego ubedo dul, man dul ne lokore 90° i thenge pa valve stem mi nwangu yub mi yabo man cego. Ball valve jutiyo kudu pol kare ikum pipelines pi poko, poko, man loko yo ma pii mol kudu. Ball valve ma juyike ku V-shaped opening de utiye ku tic maber mi jwigo pii.
TWS valve factory miyo resilient seated wafer butterfly valve YD37A1X3-16Q, Double flanged concentric butterfly valveD34B1X3-16Q, Double flanged eccentric butterfly valve according to Ser.13 or series 14, BS5163/F4/F5 /ANSI CL150 rubber seated gate valve, Y-strainer, balancing valve, back flow preventer.
3.1 Ber:
Etiye ku rwom ma piny uloyu (ma romo 0).
② Calu ecopo bedu ngo i saa mi tic (ka lubricant epe), ecopu bedu maber i kum piny ma nyai man pii ma nyai.
③ Ecopu ketho cinge ikum rwom ma malu pa pressure man temperature.
Ecopu yabo man cego nyathotho. Sawa mi yabo man mi cego pa ot moko utiye 0.05 ku 0.1 seconds kende, ma nyutho nia ecopu tiyo kudu i yub mi test bench. Ka ibe yabo man i cego valve pio pio, epe ku adwogi marac ikare mi tic.
⑤ The spherical closing part copo bedo kende kende i kabedo mi boundary.
6-- Jam tic ma jutiyo kudu ucungo maber iwi valve.
Q6 Ka valve oyabere man cego, kabedo ma juketho i iye sphere man valve seat jupoko kud i kind piny. Pieno, piny ma mol kud i valve ku ngwec ma tek bi kelo ngo nyai pa kabedo ma juketho i iye.
⑧ Etiye ku yik ma nyap man pek ma yot. Ecopu bedu ni yore maber loyo mi yubu valve pi piny ma lyeth pare nok.
Thevalvekum utiye marom. Mapire tek pi dul pa valve ma welded, ecopu ciro peko ma aa kud i pipeline.
⑩ Thenge mi cego copo ciro tung tung mi pressure ma malu ikare mi cego.
⑪ Ball valve ku kum valve ma weld maber ecopu bedu ma juyiko piny, ma gwoko piny ma iye pa valve kud i lyethu. Kwo pare ma malu copo tundo oro 30, ma weko ebedo valve maber loyo pi pipelines mi oil man natural gas.
3.2 Peko:
① Ma pire tekvalvepiny ma juketho i kom kom ma juketho i ball valve ubedo polytetrafluoroethylene (PTFE). Etiye piny ma timo ngo ikum piny moko ci man etiye ku kite ma tung tung macalo friction coefficient ma nok, tic maber, kwo ma tek, rwom ma lac mi lyethu, man tic maber mi juku piny. Ento, kit ma PTFE nen kudu, ikinde utiye coefficient ma malu pa nyai, bedo ma ngic, man thermal conductivity ma ber ongo, mito ni yub pa valve seat seal umaku jutim ikum kit ma eni. Pieno, ka piny ma juketho i iye ubedo matek, gen pa piny ma juketho i iye ubedo marac. Bende, rwom pa lyethu pa PTFE utiye piny, man ecopu tiyo kudu kende i lyethu ma piny pa 180°C. Ka lyethu ukadhu wel eni, piny ma jukubo kudu bi doko tidi. Ka waparu pi tic pi kare malac, pol kare jutiyo kudu kende i 120°C.
Tic pare mi cik utiye marac uloyu pa globe valve, asaga pi pneumatic valves (nyoke electric valves.
5. Plug Valve
Plug valve utiye valve ma lokore ma thenge ma juketho i iye utiye i ayi pa plunger. Ka iloko 90°, dhugola ma wok iwi plug juyike ni weco ku nyo poko ku dhugola iwi kum valve, ni kelo yabo nyo cego pa valve. Julwonge bende ni cock, stopcock, nyo rotary gate. Kite pa plug copo bedu cylindrical nyo conical. Tye kit mapol, ikinde utiye kit ma rwinyo, kit ma rwinyo, man kit ma rwinyo angwen. Cik pare urombo ku pa ball valve.
5.1 Ber:
E ber pi tic ma pol kare, ku yabo man cego nyathotho man yot.
② Resistance pa pii utiye nok.
③ Etiye ku kit ma yot, dit ma nok, pek pare yot, man yot ni gwoko.
Etiye ku tic maber mi mako piny.
⑤ Ma juketho ngo cik ikum yore mi ketho piny, yore mi mol pa piny copo bedu ma rwinyo.
⑥ Yeng yeng epe, man dwand utiye piny.
5.2 Peko:
Kabedo ma juketho i iye piny ubedo malac akeca, ma ukelo torque madwong man flexibility ma romo ngo.
⑧ Ka pek pare gire, dit pa diameter pa valve utiye nok.
I tic mandha, ka valve ma dit mitere, reverse plug structure umitu jutii kudu, ma copo nyayu peko ikum sealing effect.
Lembe mukende, icopo bedu agonya ni lok kuduTWS valveot thyeth.
