Ni lembe pa tic pa sealing element mi turo man mako, yub man poko, poko man rubu piny i valvpassage, kabedo mi sealing pol kare bedo ku lyethu, nyai, man rwinyo pa piny, ma weko ebedo yot ni nyayu ret.
Wec ma pire tek:the sealing surface;corrosion;erosion;wear
Tye the lembe aryo ma nyayu ret ikum piny ma jugwoko: ret pa dhanu man ret pa piny. Peko pa dhanu wok pi lembe moko calo yiku marac, yiku, yero piny ma jutiyo kudu, ketho marac, tic marac, man gwoko. Peko ma wok kud i ngom utiye rwinyu man rwinyu pa valve i tic pare man etiye pi nyai man nyai pa piny ma juketho i iye.
The lembe ma nyayu ret ikum piny ma juketho i iye copo bedu ma e:
Ber pa tic ku jam tic ma ber ongo: Eni nyuthiri i peko macalo tur, vur, man piny ma juketho i kum piny ma juketho i iye. Eni wok ikum yero marac pa welding man heat treatment, man tic marac ikare mi welding man heat treatment. Tek pa piny ma jukubo kudu utiye malo nyo piny akeca pi yero piny maber ongo nyo tic ku lyethu maber ongo. Tek pa piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny ma juketho i iye piny. Eyo, lembe mi yiku piny de utiye i lembe eni.
Peko ma wok kud i yero man tic marac: Eni nenre i timo marac mi yerovalves nimakere ku kite tic, tiyu ku valve mi cego calu valve mi juku, ma kelo kero madwong ikare mi cego, cego pio pio, nyo cego ma rwinyo ngo, ma kelo nyai man rwinyu iwi kabedo mi cego. Kethu piny marac man gwoko piny marac nyayu tic marac pa piny ma jugwoko, ma nyayuvalveni timo tic ku two man nyayu peko i kum kabedo ma juketho i iye.
Chemical corrosion of the medium: Medium ma ucungu ikum sealing surface timo chemical reacts ku sealing surface manangu eketho ngo current, ma nyayu sealing surface. Electrochemical corrosion, rwate ikind piny ma juketho i iye, rwate ikind piny ma juketho i iye ku piny ma juketho i iye manvalvekum, man bende tung tung mi rwom man oxygen ma nwang i iye, zo nyayu tung tung, ma nyayu lyethu pa electrochemical man nyayu ret pa anode-side sealing surface.
Nyoth pa piny: Eni utiye adwogi pa rwinyu, nyai, man nyai pa piny ma juketho i iye ka piny ube mol. I rwom moku, piny ma nyap ma mol i pii ucungo iwi piny ma juketho i iye, man nyayu peko i kabedo ne. Piny ma mol pio pio loko kabedo ma juketho i iye, man nyayu peko i kabedo ne. Ka piny ma ikin piny eca udore man edoko pii, bubbles ucweru man ucwalu piny ma juketho i iye, ma kelo peko i kabedo ne. Dikiri pa nyai pa piny man nyai pa kemikol pa piny ma nyayu nyai pa piny ma juketho i iye.
Peko mi cuma: Kabedo ma juketho i iye piny bibedo ma nyai, ma nyai, man ma nyai i saa mi yabo man cego. Atoms ma ni ikind piny aryo ma jukubo gi wok ikindgi i thenge mi lyethu man tegu, ma kelo adhesion phenomenon. Ka piny ario ma juketho i iye giwotho ikumgi gigi, kabedo ma gicungo i iye bedo yot ni poko. Ka roughness pa sealing surface ubedo malo, nwango lembe eni copo timere. Ka valve cego, valve disc bi goyo man bi diyo piny ma juketho i iye, ma bi kelo peko nyoke nyai i kum piny ma juketho i iye.
Peko mi olo: Kabedo ma juketho i iye piny eca bedo ku pek ma loko loko ikare ma jutiyo kudu pi kare malac, ma nyayu olo man kelo tur man delamination. Rubber ku plastic gibedo macol ingey tic kudu pi kare malac, ma weko tic migi doko nok. Kud i nyang ikum lembe ma malu ma nyayu ret ikum dhugola, jucopo neno ni pi medo ber pa dhugola pa valve, piny ma jutiyo kudu pi juku dhugola, kit dhugola maber, man yore mi timo tic umaku juyer.
TWS valve ma tiyo kurubber seated butterfly valve, Gate valve, Y-strainer, valve mi rwom, Wafe check valve, ni medo mukende.
