He aha ka plug valve?

1. Hōʻikeʻike

Plug valve ʻo kahi hapa o ka quarter-huliʻana i ka nui o ka valve i hoʻohana nuiʻia no ka hoʻokaʻawaleʻana, ', a me kekahi mau lā i hala ma nā'ōnaehanaʻoihanaʻoihana.

ʻO kāna hoʻolālā maʻalahi-kahi cylindrical a iʻole ka cylidrical a iʻole cylical plug i loko o kahi kino valve, ʻO ka hāʻule haʻahaʻa haʻahaʻa, a me ka reliability.

Ka hoʻomaopopoʻana i kāna mau loina, mea waiwai, Nā Manaʻo Metrics, a he mea pono nā noi o kaʻenehana no ke kohoʻana i ka Valve kūpono no ke kaomi kiʻekiʻe, abrasive, a iʻole nā ​​lawelawe i hoʻopaʻaʻia.

2. He aha ka plug valve?

A plug valve he hapa nui o ka hapanui, ', a me kekahi mau lā.

ʻO ke kumu aʻoaʻo e pili ana i keʻano o ke kumu cylindrical a iʻole plug plug i komo i loko o kahi kino valve, nā mea e huli ai i keʻano o ke awa i loko me ka paila no ke kaheʻole a iʻole e poloka i ka pauku.

ʻO kēia mechantim robustism e hiki ai i ka rapid 90 ° hana, hāʻawi aku i nā pono a me ka hilinaʻi i nā noi koʻikoʻi.

Nā hiʻohiʻona pale

• Ka hana-huli-huli
  Hana wikiwiki (maʻamau 90 °) - kūpono no ka hoʻokaʻawaleʻana, Pono nā hana a me nā noi e loaʻa ai nā noi ma luna o / hana hana.
• Mālu, ʻO ke ala ākea haʻahaʻa haʻahaʻa
  Hāʻawi ka piha piha piha; hoʻemiʻia i nā koho koho koho balota Closed.
• Nā hoʻonohonoho Port Port
  ʻelua-, ʻekolu- a heʻehā mau alaʻehā eʻaeʻia eʻaeʻia, Hoʻohui, ʻO ka pīhoihoi a me ka paʻakikī paʻakikī me kaʻole o nā valle he nui.
• E hōʻailona ana
  I loaʻa me Metal-to-metal Noho nā noho no nā lawelawe kiʻekiʻe / abrasive, paniʻia (PTFE / RPPFE, elastomers) noho no nā wahi bubble-pani paʻa a me ka haʻahaʻa haʻahaʻa, Oole lubricated 'ōnaehana e hoʻolōʻihi i ke ola noho i loko o ka lepo lepoʻole.

3. ʻO ka papa inoa o nā vacves nunui e ka hoʻolālāʻana

ʻO nā mea kanu Blug e kauʻia ma luna Nā Hoʻolālā Hoʻohuiʻana, keʻano hōʻailona, a me ke kahe ana.

Ke hoʻomaopopo nei i kēia mau papa e kōkua i nāʻenehana e koho i ka Valve kūpono no ke kaomi, keka ao, Holo, a me nā koi lawelawe.

E pili ana i keʻano plug

Ma muli o ke hoʻonohonohoʻana i ka waihona

E pili ana i ka hoʻolālāʻana

4. Nā mea nui a me nā mea waiwai o ka plug valve

ʻO ka hana o ka valve, durability, a me ka kūpono no nā noi kiko'ī e hilinaʻi ana i kāna nā'āpana a me nā lako.

ʻO kēlā me kēia'āpana e hoʻohālikelikeʻia me ka ikaika, keka ao, Kuupuiawi, a me ka erosion aʻo ka hanaʻana i ka hana maikaʻi a me ka hoʻokaʻawaleʻana i ka nohoʻana.

5. Nā hiʻohiʻona a me nāʻano hydraulic

ʻO ka hopena kahe (Cv) - nā'āpana maʻamau

• Nā mea kanu liʻiliʻi e hoʻopiliʻia (¼ - 1) Hiki paha Cv ~ 0.1-5.
• Nā hana maʻamau maʻamau (2-6) laulā maʻamau CV ~ 5-200 Ke hilinaʻi nei i ka hoʻolālā port (piha piha. hōʻemiʻia ke kiʻi).
• ʻO nā Vimeter nui nui (8+) hiki ke hoʻokō i nā waiwai CV kiʻekiʻe, Hoʻohālikelike i nā kumu balota a pinepine pinepine i nā valbe clobe no ka nui like.

Kaomiʻana a me ka'ā'īʻana

• Hoʻolālāʻia nā Vlug Vilves i hoʻolālāʻia no ma luna Oole Keʻaiʻai hoʻokaumi.
  ʻOiai hiki iā lākou ke hoʻohanaʻia no ka'ā'ī, ʻo lākou Kūpono loa Ma mua o nā huaʻala o ka honua no nā modula no ka pauʻana o nā mea ola nonlinear.
• Ka hoʻonuiʻana o ka pume me ka kahe a hoʻemi i ka nui o ka awa; Pono ke lawelawe kiʻekiʻe ΔP kiʻekiʻe (ʻO ka hana lehulehu a iʻole ka hōʻemiʻana i nā plugs) e pale aku ai i ka walaʻau.

6. Nā hui me nā papa hana a me nā papa

7. Ke kaʻina hana hana o ka plug valve

Ka hanaʻana o nā vag blue e hoʻopili pololei Kauhi, machining, Kāhea, a me ka ho'āʻoʻana No ka hōʻoia i ka Durability, Ke hele wāwae nei, a hilinaʻi i ka hana ma lalo o nā kūlanaʻoihana likeʻole.

Ke kalaʻana a iʻole ke kalaʻana i ke kino a me ka plug

Ka'ōpū kino a plug Hoʻokumu i ka hana o ka hana o ke kumu plug. Hiki iā lākou ke hanaʻia ma o:

• Sand cread: Maʻamau no ka medium- i nā mea nui nui. Hāʻawi i kahi kūpono i nā geomet paʻakikī, e komo pū me nā kino bort, aʻaeʻia nā hiʻohiʻona i hāʻawiʻia e like me ke kākoʻo o Trunnion.
  ʻO ka laweʻana i ka hana wela wela wela e hōʻemi i ke kaumaha kūlohelohe.
• Hoʻolei kālā (Nalowale-wax): Hāʻawi i nā meaʻokoʻaʻokoʻa a me nā papa hana kūpono, Kūpono no ka pololei a iʻole nā ​​mea liʻiliʻi a iʻole nā ​​mea i loaʻa i nā mea paʻa paʻa.
• Kākau: Hana hewa, nā mea kiʻekiʻe kiʻekiʻe no nā noi kiʻekiʻe a iʻole nā ​​noi koʻikoʻi. Ua liʻiliʻi nā Valves i nā leo a me nā mea hōʻeha maikaʻi loa, He kūpono no API 6d pipeline kūwaho.

Mīkini pololei

Ma hope o ka hoʻoleiʻana a iʻole ke kalaʻana, nā'āpana i lalo Cnc a me ka machining manual E hoʻokō i nā mea hana kūpono a me ka neʻeʻana o ka papa:

• Plug busing a me ke kauʻana: E hōʻoia i ka plug i huliʻole i ka mālamaʻana i kahi sila paʻa e kū'ē i ka noho.
• Noho machiʻi: ʻO nā nohona a me nā noho nohoʻole i hanaʻia i nā mea i hoʻopaʻaʻia i nā'āpana micron-pae.
• ʻO kaʻokoʻaʻo Port: Koʻikoʻi no nā valle-bort.
• Hoʻopau ʻili: Paulapu, Kāleka, a iʻole ka hoʻolimalimaʻana i ka friction, pale aku i ka galling, a hoʻomaikaʻi hou i nā kūlana kiʻekiʻe lōʻihi.

Paakiki a me ka lole

E hoonui i ka paakiki i abrasive, Kauike, a iʻole ka hoʻoponoponoʻana, ʻO nā plugs a me nā noho paha:

• Paʻakikī loa me Lealea, turmesn carbide, a iʻole nā ​​alloys e pili ana i nā nickel, ka hoʻonuiʻana i ke paleʻana i ke kū'ē a me ke olaʻana i ke ola lawelawe.
• Kauia Me nā papa corrosion-resistant e like me PTFE, ʻO ka hanaʻana o Nickel, a iʻole epoxy.
• Lubricated I nā kumu kūʻai kūikawā e mālama i ka hana haʻahaʻa haʻahaʻa, pale aku i ka galling, a hoʻonui i ke ola hōʻailona, kūikawā ma nā noi Slurry kiʻekiʻe kiʻekiʻe.

Kapua a me ke kūpono

ʻO kaʻaha kanaka he hana kūpono e hoʻomaka ai AliKu, hana maʻalahi, a me ke ana ana:

• Hoʻopiliʻia: E kau pono i ke kino; lubricated inā koiʻia.
• Stem a me ka hoʻonohonohoʻana o ka stunnion: Ua kākoʻoʻia nā kākoʻo a me nā kākoʻo Trunnion e hōʻemi i ka trqueting spique a hoʻopaʻa i nā plugs nui ma lalo o ke kaomi kiʻekiʻe.

FaqS

He aha kaʻokoʻa ma waena o kahi blue butt a me kahi pōpō ball?

Hoʻopili i nā Vilves Vilves i kahi kiʻi cylindrical / taped (ʻO nā mea eccentric e hōʻemi i ka lole), ʻOiai e hoʻohana ana nā kumukūʻai ball i kahi pōpō spherical.

Hoʻopili i nā valves excel i ka frasive / corrostive fell (300% ʻOi aku ka lōʻihi o ke ola ma nā slirries), ʻOiaiʻo nā koho ball ball he cheaper no ka meaʻole-abrasive, nā noi noi kiʻekiʻe.

ʻO ka plug valve valve maikaʻi loa no ka slurries abrasive?

ʻO nā lāʻau uila eccentric e hoʻopili me nā noho kaʻa manu (85-90 HRC) maikaʻi loa.

ʻO ka hoʻolālā eccentric e hāpai i ka plug i ka noho (ʻAʻohe kamaʻilio), a me nā mea e komo ai nā mea lawe aku i nā pale carbide i nā mea i hoʻopaʻaʻia mai nā mea hoʻoponopono-e hoʻolōʻihi i ka ola a hiki i 1-2 mau makahiki. 3-6 mau mahina no nā kumu ball.

Ehia mau manawa e lubricated plug valves?

Quarterly ma lalo o ka lawelawe maʻamau (pono & aila, wai); mahina no nā wai abrasive (mining). ʻO nā'ōnaehana lubricication lobrication (nā mea hao pneuutic) hiki ke hoʻonui i nā intervals i 6-12 mau mahina.

Hiki i nā mea hao ke hoʻopaʻa i nā kiʻekiʻe kiʻekiʻe?

ʻAe. ʻO nā huapalapala i kohoʻia (Lealea 6, HadELy C276) lawelawe a 815 ° C (nā mea kanu manu nula). Nā Valled-Seated Valves (Ptfe) kaupalenaʻia he 260 ° C.

He aha ka papa o ka papa o nā paila plug?

Nā'ōkuhi paʻa i hoʻopaʻaʻia (PTFE / Viton) loaʻa ansi FCI 70-2 Kakau Vi (≤0.00001% leakage) - koʻikoʻi no nā wai momona / brivent.

Loaʻa i nā alaloa ma Metal-noho i loaʻa i ka papa IV (≤0.01% leakage) - kūpono no ka lawelawe kiʻekiʻe kiʻekiʻe.

Pehea wau e hōʻemi ai i nā koi o ka torole no nā lāʻau plug?

E hoʻohana i nā plugs lubricated (Hoʻololi ka kiʻi kiʻi kiʻi-PPFETE-PTFE i ka Friction e 50%); Koho i nā hoʻolālā encleric (E kau ana i ka nohoʻana); E hōʻoia pono i ka hoʻoponopono ponoʻana (Hōʻalo i ka hoʻopaʻaʻana).
