Imodeli yevalve yaseTshayina: ukuhlangabezana neemfuno ezahlukeneyo zobunjineli, nceda ulwakhiwo lwedolophu lwanamhlanje

Ngokukhawuleza kwenkqubo yokufudukela ezidolophini yaseTshayina, imfuno yolwakhiwo lweziseko zophuhliso olwahlukeneyo iyaqhubeka nokukhula, phakathi kwayo, ivalve yokutshekisha njengenxalenye ebalulekileyo yenkqubo yolwelo lwamanzi, idlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo nozinzo lwenkqubo yehydraulic. I-China, njengesixeko esibalulekileyo semizi-mveliso emantla eTshayina, inabenzi abaninzi ababalaseleyo be-valve yokukhangela, enika ukhetho olutyebileyo lwemodeli yevalve yokukhangela ukwakhiwa kwedolophu eTshayina. Eli nqaku liza kukunika uhlalutyo oluneenkcukacha lweemodeli zevalvu yaseTshayina ukuhlangabezana neemfuno ezahlukeneyo zobunjineli kunye nokunceda ulwakhiwo lwasezidolophini lwanamhlanje.

Isishwankathelo kunye nomsebenzi wevalve yokukhangela

Ivalve yokukhangela, eyaziwa ngokuba yi-valve yokutshekisha, ivalve yokuthintela umva, ivalve ezenzekelayo yokuthintela ukubuyela ngasemva kwendawo. Umgaqo wayo wokusebenza kukuthembela kumahluko oxinzelelo ophakathi ukuvula i-valve, xa i-medium ihamba phambili, i-valve ivula; Xa i-medium ihamba kwelinye icala, i-valve iyavala. I-valve yokukhangela isetyenziswa ngokubanzi kunikezelo lwamanzi, i-drainage, i-petroleum, iikhemikhali, izikhululo zamandla, iinqanawa kunye namanye amacandelo, sisixhobo esibalulekileyo sokuthintela ukubuya kweendaba, ukukhusela izixhobo kunye nokhuseleko lombhobho.

Isibini,China itshekhi valveuhlobo kunye neempawu

1.Ivalve yokujonga ujingi

Ivalve yokukhangela i-Swing sisakhiwo esilula, kulula ukuyivula nokuvala ivalve, ilungele ubukhulu becala elincinci kunye neliphakathi, izicelo zokwahlukana koxinzelelo oluphantsi. Ibonakaliswe ngokungabikho kwe-gap phakathi kwe-disc kunye nesihlalo, esinokuthi sithintele ngokufanelekileyo ukubuyisela umva kwendawo. Kubenzi bevalve yetshekhi yaseTshayina, ivalve yetshekhi yokujingi iyimodeli eqhelekileyo.

2.Phakamisa ivalve yokukhangela

I-valve yokukhangela i-valve i-valve ene-disc phezulu nasezantsi, kwaye inomthamo omkhulu wokuhamba. Ifaneleka ikakhulu kwizicelo ezinomgangatho omkhulu kunye noxinzelelo oluphezulu. Ibonakaliswe ngekhefu phakathi kwediski kunye nesihlalo, xa i-medium ihamba phambili, i-disc iphakama kwaye i-valve ivula; Xa i-medium ihamba ngasemva, i-disc iyancipha kwaye i-valve ivale. Abavelisi bevalufa baseTshayina abanobuchwephesha bokwenza itekhnoloji, benza ukuba ivalve yokukhangela iphakamise ibe ngaphezulu ekusebenzeni.

3. Ivalve yokukhangela engqukuva

Ivalve yokukhangela i-spherical luhlobo lwevalve esebenzisa ibhola njengediski yevalve, eneempawu zokuqukuqela okunamandla kunye nokunxiba okuncinci kwesitulo. Ikakhulu ifanele ubushushu obuphezulu, uxinzelelo oluphezulu, izicelo ezizonakalisayo ezomeleleyo. Abavelisi bevalufa yetshekhi yaseTshayina bathembele kubuchwepheshe bemveliso ephucukileyo, benza ivalve yetshekhi engqukuva izinze kwaye ithembekile ekusebenzeni.

4. Ivalve yokujonga idiski ephindwe kabini

I-valve yokujonga i-disc ephindwe kabini yisakhiwo esineediski ezimbini, kunye ne-torque encinci yokuvula kunye nokuvala, ukusebenza kakuhle kokutywinwa kunye nokunye. Ikakhulu ilungele ukuhanjiswa kwamanzi ezidolophini, i-drainage kunye nolunye umahluko ophantsi woxinzelelo, izicelo ezinkulu zokuhamba. Abavelisi baseTshayina bajonga ivalve ngoyilo lokuphucula, ukuze ivalve yokujonga i-flap ephindwe kabini ukuqinisekisa ukusebenza ngaxeshanye, intle ngakumbi kwaye iyasebenza.

Okwesithathu, ityala lesicelo seImodeli yevalvu yetshekhi yaseTshayinakulwakhiwo lwasezidolophini

1. Iziko likamasipala lokucoca ilindle

Indawo yokucoca ugutyulo lwamanzi amdaka edolophu ithatha ivalve yokujonga i-swing eveliswe lishishini laseTshayina, elithintela ngokufanelekileyo umva we-medium kumbhobho welindle kwaye liqinisekise ukusebenza okuqhelekileyo kwendawo yokucoca ugutyulo.

2. Inkampani yamanzi yesixeko

Kwinkqubo yonikezelo lwamanzi yenkampani yamanzi edolophu, i-valve yokuphakamisa yokukhangela eveliswe yinkampani yaseTshayina isetyenziselwa ukuqinisekisa ukusebenza okukhuselekileyo kunye nokuzinzileyo kwenkqubo yokubonelela ngamanzi kunye nokubonelela ngamanzi okusela aphezulu kuluntu.

Iv. Ukuqukumbela

Isishwankathelo, ngokukhethwa okutyebileyo kweemodeli kunye neempawu ezibalaseleyo zokusebenza, iimodeli ze-valve ze-China zihlangabezana neemfuno ezahlukeneyo zobunjineli kunye nokubonelela ngenkxaso eqinile yokwakhiwa kwezixeko zanamhlanje e-China. Kwixesha elizayo, kunye nenkqubela phambili eqhubekayo yenkqubo yasezidolophini yaseTshayina, ukusetyenziswa kweevalvu zetshekhi kulwakhiwo lwasezidolophini kuya kuba kubanzi ngakumbi, kwaye abavelisi beevalvu zaseTshayina baya kuqhubeka ukudlala indima ebalulekileyo kwaye bafake isandla ngakumbi kulwakhiwo lwasezidolophini lwaseTshayina.
