Gate valve ubedo valve ma pol, ma jutiyo kudu lee, ma jutiyo kudu lee i gwoko pii, metallurgy man tic mange, tic pare mapol ungiyure i soko, TWS i kite maber man tic mi temo man tic mi pimo pi oro madwong, man ikum nwangu gate valves utiye ku sayusac moko, ento bende ikum tic ku gate valves, peko man lembe mukende mapol timo sayusac maber.
Nimakere ku kit ma tung tung pa gate valves, gate valves jupoko gi i dul aryo: wedge type man parallel type.
Gate plate pa wedge gate valve utiye wedge-shaped, man kabedo mi cego utiye i dyere pa channel, man wedge ma ni ikind gate plate ku valve seat jutiyu kudu pi ketho sealing (closing). Wedge plate copo bedu dhugola acel nyo dhugola aryo.
Kabedo ma juketho i iye parallel gate valve utiye parallel ku wadi man perpendicular ku center line pa channel, ma jupoko i dul aryo: ku man ma epe ku yore mi yabo. Otiye ram ario ku yore mi juku, ka ram ucidhi piny, wedge pa ram aryo ma rwate ucungo iwi valve seat ku inclined plane, flow channel jupoko, ka ram ucungo man oyabere, wedge jupoko kud i kum ram mating surface, ram utingo malu nitundo i bor moko, man wedge jugwoko malu ku boss iwi ram. Ka ram umondo i kom valve i thenge ario ma tung tung, tego pa pii jutiyo kudu pi diyo ram iwi kum valve i thenge mi wok pa valve ni juku pii.
Nimakere ku wotho matung tung pa valve stem ka dhugola oyabe man cego, gate valves jupoko i dul aryo: rising stem gate valves man concealed stem gate valves. Valve stem man gate pa rising stem gate valve ucungo man podho i sawa acel ka jube yabo nyo ju cego; ka valve mi dhugola mi stem ma ungire oyabere nyo cego, valve stem kende re ma lokore, man dongo man podho pa valve stem copo nen ungo, man valve plate dongo nyo podho. Ber pa rising stem gate valve utiye nia bor pa channel opening copo bedu nimakere ku rising height pa valve stem, ento bor pa valve copo bedu ma nok. Ka inen cing cing nyo cing cing, lok cing cing nyo cing cing yo yo pa sawa mi cego valve.

02. Wedge gate valve
Wedge gate valve application occasions: i kit valve matung tung, gate valve ubedo acel ma jutiyo kudu lee, etiye maber kende pi yabo nyo cego, ecopu bedu ngo pi loko man throttling.
Wedge gate valves pol kare jutiyu kudu ikabedu ma cik moko ope ikum dit pa valve, man kite ma jutiyo kudu utiye matek. Ku lapor, piny ma jutiyo kudu ma lyethu man ma tek mito nia juketh piny ma juketho i iye pi kare malac.
Pol kare, tic ku pressure ma malu, pressure ma malu (tug tung madit pa pressure), pressure ma piny (tug tung pa pressure ma nok), dwand ma nok, cavitation man vaporization, high temperature medium, low temperature (cryogen), wedge gate valve juyero. Ku lapor, jutiyo kudu lee i tic mi kero pa mac, yiko petroleum, tic mi petrochemical, tic mi oil i nam, tic mi pii man tic mi yiku pii ma rac i gedo mi adhura, man tic mi kemikol.
Cik mi yero:

(6) Ka ecopu yabe nyo cego, man ecopu bedu ngo pi yiko man throttling, wedge gate valve copu bedu.
3. Peko ma rwinyo man gwoko
01. Peko ma rwinyo man the lembe ma nyayu gate valves
I ngei tic ku gate valve, peko ma e piny eni pol kare timere pi lyethu ma rwinyo, tegu, lyethu man wotho pa piny acel acel.
(1) Leakage: Tye kit aryo, niwacu leakage ma woko man leakage ma iye. Cwir ma wok woko pa valve julwonge ni cwir, man cwir utiye pol kare i stuffing boxes man flange connections.
The lembe ma nyayu pii ma wok kud i sanduku mi pong piny: kit nyo ber pa piny ma juketho i iye urombo ngo ku piny ma mitere; Aging packing nyoke stem wear; Gland pa packing ma gony Abrasion iwi kor yen.
The lembe ma nyayu pii ma wok kud i flange: piny nyo dit pa gasket uromo ngo ku piny ma mitere; Ber pa tic pa flange sealing surface; ketho cing ikum bolts ma rwate ngo maber; Piping ne juyike ngo maber, ma ukelo pek madwong ikum kabedo ne.
The lembe ma nyayu pii ma wok kud i valve: Cwiny ma wok kud i cego pa valve ubedo pii ma wok kud i iye, ma wok kud i nyoth pa valve nyoke theng cing ma ucungo.
(1) Corrosion pol kare wok ikum corrosion pa kama juketho iye valve, valve cover, valve stem man flange. Nyoth utiye pi tic pa piny ma iye, ento bende pi wodhu pa ions kud i filler man gasket.
(2) Abrasion: loko piny ma wok iwi ngom nyoke poko piny ma timere ka ram man valve seat gitiye ka ngwec i thenge moko.
02. Gwoko pavalves mi dhugola
(1) Yubu pii ma woko pa valve
Ka ibe diyo packing, gland bolt umaku juketh maber kara gland kud utur man ewek kabedo pi diyo. I saa marom ku diyo pa packing, valve stem umaku julok kara packing ikum valve stem ubed marom, man juku pressure kud utho, kara kud unyoth rotation pa valve stem, umed wear pa packing, man jwigo kwo pa valve. Iwi valve stem utiye abrasive, kara medium ubed yot ni wok woko, man umitu jutim kudu pi kwanyu ret ma ni iwi valve stem ma podi jutiyo kudu ngo.
Pi pii ma wok kud i flange, ka gasket unyothere, umitu julok; Ka piny ma jutiyo kudu pi gasket juyeru ngo maber, piny ma copo rombu ku yeny mi tic umaku juyer; Ka tic maber pa flange sealing surface utiye marac, flange sealing surface umaku juwodhe woko man jutim kendu ikume nitundo ma eromo.
Mi medo, diyo maber pa flange bolts, yubu pa pipe maber, man jwigo peko madwong ikum flange connection zo gikonyo pi juku leakage i flange joint.
(2) Yubu pii ma mol i valve
Yubu pa pii ma mol i iye utiye mi jwigo peko ikum kabedo ma jukubo iye piny man jukubo ku cinge ma unyai ungo (ka ring ma jukuboth kudu ju diyo i valve plate nyoke kom ku thread). Ka kabedo ma juketho i iye juyike iwi valve body man valve plate, epe ku peko mi root man leakage.
Ka kabedo ma juketho i iye unyothere marac, man kabedo ma juketho i iye ubedo ku ring ma juketho i iye, ring macon ucikere ni kwanyu man juketho ring manyen mi ketho cing i iye; Ka kabedo mi juku cing juyike iwi valve, kabedo mi cing ma unyothere umaku juwodhe woko, man ingeye cing cing manyen nyo kabedo ma jutiyo kudu ucikere ni bedo kabedo manyen mi cing. Ka nyai, nyai, nyai, nyai man peko mange ikum piny ma juciko kudu utiye piny pa 0.05mm, jucopo jwigo gi ku nyai.
Ka ring pa seal ucungo-i iye man ucungo, PTFE tape nyo rangi ma tar ma gwai jucopo ketho piny pa valve seat nyoke seal ring groove, man judham i seal ni ketho theng seal ring upong; Ka seal ubedo threaded, PTFE tape nyo rangi matar ucikere ni bedu ikind threads ni juku pii kud ucwal ikind threads.
(3) Yubu pavalvenyal
I kura madit, kum valve man bonnet gibedo ku buru marom, man valve stem pol kare gibedo ku vur. Ka juyubu, juwodh piny ma nyayu lyethu ma kwong, man valve stem ku pitting pits umaku jutim kudu iwi lathe mi jwigo depression, man packing ma tye ku slow-release agent umaku juti kudu kakare, nyo packing umaku juyike ku pii ma leng pi kwanyu ions ma nyayu corrosive effect ikum valve stem i packing.
(4) Yiko pa ret ikum piny ma juketho i iye
I tic kuvalve, kabedo ma juketho i iye umitu jugwoku kud utur, man torque umitu kud ubed malac akeca ka valve cego. Ka kabedo ma juketho i iye ubedo ma nyai, jucopo kwanyu ne ku tiyo ku cinge.
Mir angwen, nwangu pa gate valves
I lembe mi soko ma kawoni man yeny pa jutic, iron gate valves utiye piny madit. Calu janen wi ber pa piny, ikum bedo ku ngec ikum pimo ber pa piny, umitu wabed ku ngec maber ikum piny ne gire.
01. Thelembe mi pimo valves mi dhugola mi cuma
Temo pa iron gate valve ucungo iwi cik mi ngom GB/T12232-2005 "General Valve Flange Connection Iron Gate Valve".
02. Piny mi ngiyo pa valve mi dhugola mi cuma
Ma pire tek uketho i iye: lanyuth, pek pa ot ma nok, pima pa cing, pima pa cing, man mukende mapol, ma rwom pa cing, rwom, temo pa cing ubedo piny ma pire tek mi ngiyo, ento bende piny ma pire tek, ka piny moko utiye ma rwate ngo, jucopo ngiyo gi ni piny ma rwinyo ngo.
I lembe ma nok, ngiyo ber pa piny ubedo piny mapire tek i ngiyo piny, ber pare nenre gire, calu jurutic mi ngiyo piny, umitu wamedara ni medo kero migi gigi, ungo kende ni timo tic maber i ngiyo piny, ento bende ni bedo ku nyang ikum ngiyo piny, kara watim tic maber i ngiyo.
