(1) Thevalavusichigwira ntchito.
Matenda a shuga ndi zifukwa zake ndi izi:
1. Palibe gwero la gasi. ④ mpweya gwero lalikulu chitoliro kutayikira.
2. Gwero la mpweya, palibe chizindikiro.① DCS linanena bungwe cholakwika, ② kusokoneza chingwe chingwe; ③ cholakwika cha malo;
3. Malo alibe mpweya.① Sefa yotsekeka; ② kuthamanga kwa valve kulephera ③ kutayikira kwa chitoliro kapena kutsekeka.
4. Choyikapo chili ndi gwero la gasi ndipo sichimatulutsa. Mphuno yatsekedwa.
5. Signal, osachitapo kanthu.① Kore ndi mpando wokhazikika, ② tsinde lopindika kapena losweka; ③ mpando pachimake achisanu kapena coke chipika dothi; ④ actuator masika dzimbiri chifukwa ntchito yaitali; ⑤ valavu kasupe wosweka kapena diaphragm kuonongeka; ⑥ valavu solenoid kulephera; ⑦ tsinde lokhazikika.
(2) Ntchito ya valve ndi yosakhazikika.
Zowopsa ndi zoyambitsa zake ndi izi:
1. Kuthamanga kosakhazikika kwa mpweya. Kulephera kwa ma valve opanikizika.
2. Kuthamanga kwa siginecha sikukhazikika.① PID magawo owongolera; ② zotulutsa zowongolera ndizosakhazikika; ③ mawaya ndi omasuka.
3. Kuthamanga kwa gwero la mpweya ndikokhazikika, ndipo kukakamiza kwa siginecha nakonso kumakhala kokhazikika, koma machitidwe a valavu yowongolera akadali osakhazikika.① Kulakwitsa kwa malo; ② linanena bungwe chitoliro ndi mzere kutayikira; ③ actuator ndi yolimba kwambiri; kukaniza kwakukulu mu ④ kuyenda kwa tsinde; ⑤ Mkhalidwe wogwirira ntchito ndi wosakhazikika, momwe zilili pano sizikugwirizana ndi kusankha; ⑥ diaphragm kapena kasupe wasweka; ⑦ mutu wa silinda kapena nembanemba ukutuluka; ⑧ valavu mkati mwawonongeka; ⑨ malo oyezera ndi osakhazikika.
(3) Kugwedezeka kwa vavu.
Zowopsa ndi zoyambitsa zake ndi izi:
1. Vavu yowongolera imanjenjemera pamlingo uliwonse wotsegulira.① Thandizo losakhazikika; gwero la kugwedera pafupi ②; ③ spool ndi tchire; kukomoka kwambiri.
2. Vavu yowongolera imanjenjemera pafupi ndi malo otsekedwa.① Vavu yowongolera ndi yayikulu ndipo imagwiritsidwa ntchito potsegula pang'ono; ② valavu yokhala ndi mpando umodzi siyenera kugwira ntchito.
(4) Zochita za valve zimachedwa.
Zochitika ndi zomwe zimayambitsa kukhumudwa ndi izi:
Tsinde la valavu limakhala losawoneka bwino panthawi yobwereza.① Kutsekeka kwa bondi mu valavu; ② PTFE kulongedza kuwonongeka kuumitsa kapena graphite kulongedza lubricating mafuta youma; ③ kulongedza ndi kothina kwambiri, kukana kukangana kumawonjezeka; ④ kukana kwakukulu chifukwa cha tsinde la valve siwowongoka; ⑤ mphamvu ya silinda si yayikulu mokwanira, silinda kapena gwero la gasi; ⑥ ntchito kusintha chikhalidwe; ⑦ vuto la masika; ⑧ kulephera kwa malo.
(5) Kuchulukira kwa valve kumawonjezeka.
Zifukwa za kutayikira ndi motere:
1. Voliyumu yayikulu yotayikira pomwe valavu yatsekedwa kwathunthu.① Pakatikati pa valve yatha, kutayikira kwamkati kumakhala kwakukulu, ② valavu sisinthidwa ndikutsekedwa; ③ ziro zamakina sizisinthidwa.
2. Vavu sangathe kufika pamalo otsekedwa kwathunthu.① Kusiyana kwapakati papakati ndi kwakukulu kwambiri, torque ya actuator ndi yaying'ono kwambiri, mphamvu ya mpweya sikwanira, ndipo valavu sinatseke; pali zinthu zakunja mu ② vavu; ③ tchire ndi kuphika; mkati mwa ④ valavu yawonongeka.
(6) Otaya chosinthika osiyanasiyana ndi ang'onoang'ono.
Chifukwa chakuthupi: Pakatikati pa valavu kapena mpando wa vavu umakhala wocheperako, kotero kuti kutsegula kwabwinoko kumakulirakulira.
Malingaliro a kampani Tanggu Water Seal Valve Co., Ltd., ndi matekinoloje zotanuka mpando valavu kuthandiza mabizinesi, mankhwala ndi mpando zotanukavalavu ya butterfly, valavu ya butterfly, valavu yamagulugufe awiri,valavu yamagulugufe awiri a flange eccentric, valve balance, wafervalavu yoyendera mbale ziwirindi zina zotero. Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
