Valve ya plug ya manja
✧ Kufotokozera
Valve yamtundu wa plug ndi kapangidwe kake ka valavu ya pulagi komwe pulagi yozungulira kapena yopindika mkati mwa thupi la valavu imagwiritsidwa ntchito kuwongolera kutuluka kwamadzi. Pulagi ili ndi gawo lodulidwa lomwe limagwirizana ndi njira yodutsa pamene ili pa malo otseguka, kulola kuti madzi apite, ndipo akhoza kuzunguliridwa kuti athetseretu kutuluka pamene atsekedwa. -kutha mphamvu, kuchepa kwapang'onopang'ono, ndikugwiritsa ntchito mosiyanasiyana pamagwiritsidwe osiyanasiyana, kuphatikiza njira ndi mafakitale ogwiritsira ntchito zamadzimadzi ndi mpweya. ndi gasi, petrochemical, mankhwala, ndi mafakitale ena ndondomeko chifukwa cha kudalirika ndi luso kusamalira mitundu yosiyanasiyana ya madzimadzi. Mavavuwa amathanso kukhala ndi zinthu monga pulagi yopaka mafuta, kuwongolera kuthamanga, ndi zida zosiyanasiyana zomangira kuti zigwirizane ndi zofunikira zenizeni ndi machitidwe opangira. omasuka kufunsa.
✧ Mawonekedwe a valavu ya pulagi ya mtundu wa Sleeve
1. kapangidwe kazinthuzo ndi kokongola, kusindikiza kodalirika, moyo wautali wosindikiza, magwiridwe antchito apamwamba, kutsanzira mogwirizana ndi njira zokometsera.
2. Kupyolera mu malaya ofewa ndi zitsulo pulagi kusokoneza mgwirizano kuonetsetsa kusindikiza, amphamvu chosinthika.
3. valavu ikhoza kukhazikitsidwa mokwanira, osayendetsedwa ndi njira yoyika; Valve ndi yaying'ono kukula kwake ndipo ilibe zofunikira zapadera pa malo oyika.
4. valavu ikhoza kugwiritsidwa ntchito pakuyenda kwa njira ziwiri, zosavuta kupanga mu mawonekedwe ophatikizika ambiri, zosavuta kuyendetsa kayendedwe ka payipi.
5. pali milomo yachitsulo ya 360 ° yapadera pakati pa manja ndi thupi la valve, yomwe imatha kuteteza bwino ndi kukonza manjawo, kuti asagwedezeke ndi pulagi, ndipo amatha kusindikiza malaya ndi kukhudzana kwa thupi la valve kudalirika kwambiri. ndi khola.
6. pulagi ikazungulira, imakanda malo osindikizira, ikupereka ntchito yodzitchinjiriza, yoyenera pazambiri komanso zosavuta zowonera.
7. valavu alibe patsekeke mkati kudziunjikira sing'anga.
8. valavu ndi yosavuta kupanga mu mawonekedwe oletsa moto.

✧ Pambuyo pa Ntchito Yogulitsa
Ntchito yogulitsa pambuyo pa valve yoyandama yoyandama ndiyofunikira kwambiri, chifukwa nthawi yake yokha komanso yogwira ntchito pambuyo pogulitsa imatha kutsimikizira kuti ikugwira ntchito nthawi yayitali komanso yokhazikika. Zotsatirazi ndi zomwe zili mkati mwa ntchito zogulitsa pambuyo pa mavavu ena oyandama a mpira:
1.Kuyika ndi kutumiza: Ogwira ntchito pambuyo pa malonda adzapita kumaloko kukayika ndi kukonza valve yoyandama ya mpira kuti atsimikizire kuti ikugwira ntchito mokhazikika komanso yokhazikika.
2.Maintenance: Nthawi zonse sungani valavu ya mpira yoyandama kuti muwonetsetse kuti ili bwino kwambiri ndikuchepetsa kulephera.
3.Kuthetsa mavuto: Ngati valavu yoyandama ya mpira ikulephera, ogwira ntchito pambuyo pa malonda adzachitapo kanthu pa nthawi yaifupi kwambiri kuti atsimikizire kugwira ntchito kwake.
4.Kusintha kwazinthu ndi kukonzanso: Poyankha zipangizo zatsopano ndi matekinoloje atsopano omwe akubwera pamsika, ogwira ntchito pambuyo pa malonda adzalimbikitsa mwamsanga kukonzanso ndi kukonzanso njira zothetsera makasitomala kuti awapatse mankhwala abwino a valve.
5. Maphunziro a chidziwitso: Ogwira ntchito pambuyo pa malonda adzapereka maphunziro a chidziwitso cha valve kwa ogwiritsa ntchito kuti apititse patsogolo kasamalidwe ndi kasamalidwe ka ogwiritsa ntchito pogwiritsa ntchito ma valve oyandama. Mwachidule, ntchito yogulitsa pambuyo pa valve yoyandama iyenera kutsimikiziridwa mbali zonse. Ndi njira iyi yokha yomwe ingabweretsere ogwiritsa ntchito bwino ndikugula chitetezo.
