Kuvwuntauzya bubotu abubi bwamisyobo yosanwe yamavalvu 2

3. Bbola lya Valve

Ibbola lya vvalavu lyakasanduka kuzwa ku vvalavu lya pulagi. Cibeela chakwe chakujalula akujala nchibbola, mpawo bbola lilazungaana 90° kuzinguluka ntalisyo ya valve stem kuti lizuzikizye makanze aakujalula akujala. Ibbola lyavalvu lilabelesyegwa kapati mumapayipi kutyola, kwaabila, akucinca nzila yakuzuza kwachintu. Ibbola lyavalvu lyakabambilwa kuti lijalulwe mbuli V alimwi lilaa mulimo mubotu wakulanganya kweenda kwamaanzi.

Fakitali ya TWS valve ilapa vvalavu yabutterfly YD37A1X3-16Q, Double flanged concentric butterfly valveD34B1X3-16Q, Ivalvu iijisi mababa obile kweendelanya a Ser.13 naa series 14, BS5163/F4/F5 /ANSI CL150 vvalavu iikkede aamulyango wa raba, Y-strainer, vvalavu yakubamba, ilesya kuzwa musule.

3.1 Bubotu:

Ilijisi nguzu zyakukazya kuzuza zili munsi kapati (aasika ku 0).

Mbwaanga tachikonzyi kujatikizyigwa muchiindi chakubeleka (kunyina mafuta), chilakonzya kubelesegwa kabotu kuzintu zikonzya kubola azintu zitabiliki kapati.

ilakonzya kuzuzikizya kujala koonse mukati kakusinikizyigwa kupati akupya.

ilakonzya kujalula akujala chakufwambaana. Chiindi chakujalula akujala zimwi zintu zili buyo a 0.05 kusikila ku 0.1 masekondi, ikusinizya kuti zilakonzya kubelesegwa mumabbokesi aakusunka. Notujalula akujala vvalavu chakufwambaana, kunyina ntenda muchiindi chakubeleka.

Cibeela chakujala chakali mbuli bbola chilakonzya kulibikka aawo mpaali kumunyinza.

⑥-- Chibelesyo chibelesegwa chilijalilidwe kabotu aavalvu.

Mubuzyo⑦ Eelyo vvalavu nolijalukide akujalwa, busena bwakujala bbola achuuno cha vvalavu zilaandaanizyigwa kuzwa aakati. Aboobo, chintu chili akati-akati chiinda mumulyango chakufwambaana tachikonzyi kweeta kubola kwabusena bwakujala.

⑧ Chili abupange bupati alimwi chilemu pe. Chilakonzya kwaambwa kuti ninzila iili kabotu yakubamba mavwili muzibelesyo zitakwe kupya kapati.

Ivvalavumubili ulikozyenye. Ikapati aatala amubili wavalvu, ulakonzya kuliyumya kukukataazikana kuzwa kumupayipi.

Cibeela chakujala chilakonzya kuliyumya mukwiimpana kwakusinikizyigwa kupati muchiindi chakujala.

⑪ Ibbola lya bbola lijisi mubili wa valve uuzwide ulakonzya kuzikkwa ansi, akukwabilila zibeela zyamukati zya valve kuti zitanyonyooki. Buumi bwayo bwakubeleka bulakonzya kusika myaaka iili 30, akupa kuti ibe ntalisyo mbotu kapati yamapaipi aamafuta aamuwo.

3.2 Zibi:

Chipativvalavuchintu chakujala chibbula cha ball valve nchintu cha polytetrafluoroethylene (PTFE). Tachikwe nguzu kuzintu zyoonse zyamakemikalu mpawo chili abube buzulide mbuli bbivwe lisyoonto, kubeleka kabotu, kutachembaala, kupya kupati, akubeleka kabotu kwakujala. Nokuba boobo, bube bwa PTFE, kubikkilizya akuvwunguluka kupati, kulimvwa kutontola, akutontola kutali kabotu, kuyandika kuti bupange bwachikwabilizyo cha valve bweelede kuchitwa kuzinguluka bube oobu. Aboobo, eelyo zintu zyakujala noziyuma, kusyomeka kwakujala kulanyonganizyigwa. Kwiindawo, zyeelelo zyakukazya kupya kwa PTFE zili munsi, mpo zilakonzya kubelesegwa biyo muchiindi chakupya munsi aa 180°C. Eelyo kupya kwainda mweelwe ooyu, zintu zyakujala zilachembaala. Twalanga kubelesya kwachiindi chilamfu, kanjikanji chibelesegwa biyo a 120°C.

② Kubeleka kwayo kwabweendelezi nkubyaabi kwiinda kwa globe valve, ikapati kuma valve aamuwo (naa ma valve aamagesi.

5. Pulagi Valve

Ipulagi valve yaamba valve iizunguluka oomo chibeela chakujala chili muchimo che plunger. Kwiinda mukuzungaanya 90°, nzila iijulidwe aa pulagi ilachitwa kuti ijatane naa kwaandaanizyigwa kuzwa kumulyango uujalukide amubili wa vvalavu, kuzuzikizya kujalulwa naa kujalwa kwa vvalavu. Alimwi wiitwa kuti nkumba, nkomo, naakuti mulyango uuzunguluka. Bupange bwa pulagi bulakonzya kuba mbuli bbola naa mbuli kkoni. Kuli misyobo myiingi yayo, kubikkilizya amusyobo uululamika, musyobo uutola nzila zyotatwe, anzila zyone. Njiisyo yayo ilikozyene ayeyo ya ball valve.

5.1 Bubotu:

Chili kabotu kubelesegwa chiindi chiingi, akujula akujala chakufwambaana mpawo chakufwambaana.

Ikukazyigwa kwamaanzi nkusyoonto.

③ Chili abupange buuba, bupati buniini, chili abulemu buniini, mpawo nchuubauba kubamba.

Chili amulimu mubotu wakujala.

Kakwiina kulesyegwa anzila yakubikka, nzila yakuzuza kwachintu ilakonzya kuba yakulisalila.

Kunyina kuzungaana, mpawo muzuzumo uli munsi.

5.2 Zibi:

Busena bwakujala mbupati loko, mpawo eezi zipa kuti kube nguzu zyiingi loko akubula nguzu zyakuzungaana.

⑧ Kakuli kujatikizyigwa abulemu bwayo, bupati bwabwaanda bwavalvu buli munsi.

Mukubelesya kwini, ikuti naa kuyandika vvalavu mpati, kweelede kubelesyegwa nzila yakujokela musyule, eeyo iikonzya kunyonganya kujala.

Majwi manji, ulakonzya kutuminana kakunyina kubbadalwaTWS valvebusena bwamabbindawuko.
