Hydraulic wedge ọnụ ụzọ ámá valve DN400 PN25

1. Nkọwa na atụmatụ isi

A Hydraulic Wedge Gate Valve bụ valvụ ngagharị kwụ n'ahịrị ebe a na-ebuli ma ọ bụ wedata diski nwere ụdị wedge site na onye na-arụ ọrụ hydraulic iji chịkwaa nrutu nke mmiri.

Ihe ndị dị mkpa maka nha na klaasị a:

• Nhazi zuru oke: dayameta dị n'ime ya dabara na ọkpọkọ (DN400), na-ebute oke nrụgide dị ala mgbe emepere nke ọma ma na-enye ohere maka pig pig.
• Ntugharị Bidirectional: Kwesịrị ekwesị maka ịgbanye n'akụkụ ọ bụla.
• Stem na-ebili: Ụkwụ na-ebili ka valvụ meghere, na-enye ihe ngosi doro anya nke ọnọdụ valvụ ahụ.
• Metal-to-Metal Sealing: A na-ejikarị wedge na mgbanaka oche nwere ihu siri ike (dịka ọmụmaatụ, ya na Stelite) maka mbuze na iyi nguzogide.
• Mwube siri ike: Ezubere ijikwa nrụgide dị elu na ike, na-ebute ahụ dị arọ na nke na-adịgide adịgide, na-esitekarị na nkedo ma ọ bụ nchara arụpụtara.

2. Isi ihe

1. Ahụ: Isi ihe nwere nrụgide, nke a na-esi na Carbon Steel (WCB) ma ọ bụ igwe anaghị agba nchara (CF8M/316SS). Ngwunye flanged (dịka, PN25/ASME B16.5 Klas 150) bụ ọkọlọtọ maka DN400.
2. Bonnet: Na-agbanye n'ahụ ahụ, na-arụ ụlọ ahụ ma na-enye oke nrụgide. Ọtụtụ mgbe, a na-eji bonnet gbatịa eme ihe maka mkpuchi mkpuchi.
3. Wedge (Ọnụ Ụzọ Ámá): Akụkụ akara akara. Maka PN25, weji na-agbanwe agbanwe na-adịkarị. Ọ nwere mkpụkpụ ma ọ bụ uzo n'akụkụ gburugburu ya nke na-enye ohere ka wedge gbanwee ntakịrị, na-eme ka akara aka na-akwụ ụgwọ maka obere mgbanwe na nhazi oche n'ihi mgbasawanye ọkụ ma ọ bụ nrụgide ọkpọkọ.
4. Stem: Ogwe eriri nwere ike dị elu (dịka ọmụmaatụ, SS420 ma ọ bụ 17-4PH igwe anaghị agba nchara) nke na-ebufe ike site na onye na-eme ihe gaa na wedge.
5. Mgbanaka oche: mgbanaka nwere ihu siri ike apịara ma ọ bụ gbado ya n'ime ahụ nke weji na-emechi ya. Ha na-emepụta ihe mgbochi siri ike.
6. Mbukota: Akara (na-emekarị graphite maka oke okpomọkụ) gburugburu azuokokoosisi, dị n'ime igbe nri, iji gbochie ntanye na gburugburu ebe obibi.
7. Hydraulic Actuator: Ụdị piston ma ọ bụ scotch yoke actuator kwadoro site na nrụgide hydraulic (ọkachamma mmanụ). Ọ na-enye oke ike / mkpali achọrọ iji rụọ ọrụ nnukwu valvụ DN400 megide nrụgide dị iche iche.

3. Ụkpụrụ Ọrụ

• Imeghe: A na-ebufe mmiri mmiri hydraulic n'ime ihe na-eme ihe, na-ebugharị piston. A na-atụgharị mmegharị a ka ọ bụrụ yoke rotary (scotch yoke) ma ọ bụ linear (piston linear) nke na-atụgharị valvụ ahụ. Ụkwụ ahụ na-abanye n'ime eriri ahụ, na-ebuli ya kpamkpam n'ime bonnet, na-egbochi ụzọ mgbaba.
• Mmechi: A na-ebufe mmiri mmiri hydraulic n'akụkụ nke ọzọ nke onye na-eme ihe, na-atụgharị mmegharị ahụ. Ụkwụ ahụ na-agbagharị ma na-akwada wedge ahụ n'ime ebe a na-emechi emechi, ebe a na-agbanye ya na mgbanaka oche abụọ ahụ, na-emepụta akara.

Ihe dị mkpa: Emebere valvụ a maka ịnọpụ iche (meghere nke ọma ma ọ bụ mechie kpamkpam). E kwesịghị iji ya mee ihe maka nkwụsịtụ ma ọ bụ nchịkwa mmiri, n'ihi na nke a ga-eme ka ịma jijiji, cavitation, na mmebi ngwa ngwa nke wedge na oche.

4. Ngwa a na-ahụkarị

N'ihi nha ya na ọkwa nrụgide ya, a na-eji valvụ a na-achọ ngwa mmepụta ihe:

• Mbufe mmiri & isi ihe nkesa: ikewapụ akụkụ nke nnukwu pipeline.
• Osisi ọkụ: Sistemụ mmiri jụrụ oyi, ahịrị mmiri nri.
• Mmiri Usoro mmepụta ihe: Nnukwu ụlọ ọrụ mmepụta ihe.
• Osisi Desalination: Elu-nrụgide reverse osmosis (RO) ahịrị.
• Ngwuputa Ngwuputa na Ngwuputa Ngwuputa: pipeline slurry (ya na nhọrọ ihe kwesiri ekwesi).

5. Uru na ọghọm

6. Ihe dị mkpa maka nhọrọ na ojiji

• Nhọrọ ihe: Dakọtara ihe ahụ / wedge / oche (WCB, WC6, CF8M, wdg) na ọrụ mmiri (mmiri, corrosivity, okpomọkụ).
• Njikọ njedebe: Gbaa mbọ hụ na ụkpụrụ flange na chere ihu (RF, RTJ) dakọtara na pipeline.
• Ngalaba Ike Hydraulic (HPU): valvụ ahụ chọrọ HPU dị iche iji mepụta nrụgide hydraulic. Tụlee ọsọ ọrụ achọrọ, nrụgide, na njikwa (mpaghara/ime obodo).
• Ọnọdụ ọdịda ọdịda: Enwere ike ịkọwa onye na-eme ihe dị ka Fail-Open (FO), Fail-Closed (FC), ma ọ bụ ọdịda-in-Last-Position (FL) dabere na ihe nchekwa chọrọ.
• Valve By-Pass: Maka ngwa nrụgide dị elu, a na-etinyekarị obere valvụ gafere (dịka ọmụmaatụ, DN50) iji mee ka nrụgide gafee wedge ahụ tupu imeghe valvụ isi, na-ebelata ike ọrụ achọrọ.

Na nchịkọta, Hydraulic Wedge Gate Valve DN400 PN25 bụ nnukwu ọrụ na-arụ ọrụ nke ọma, nke na-arụ ọrụ dị arọ maka ịkwụsị kpamkpam ma ọ bụ malite na-asọpụta mmiri na nnukwu ọkpọkọ dị elu. Ọrụ hydraulic ya na-eme ka ọ dabara maka ebe dịpụrụ adịpụ ma ọ bụ akpaaka dị oke mkpa.
