Hydraulic wedge gedhi vharafu DN400 PN25

1. Tsanangudzo uye Zvinhu Zvikuru

A Hydraulic Wedge Gate Valve iine mutsara inofamba vharafu apo dhisiki (gedhi) rakasimudzwa kana kuderedzwa ne hydraulic actuator kudzora kuyerera kwemvura.

Zvinokosha zvehukuru uye kirasi iyi:

• Yakazara Bore Dhizaini: Iyo dhayamita yemukati inofanana nepombi (DN400), zvichikonzera kuderera kwakanyanya kudonha kana yakavhurika zvakazara uye ichibvumira pombi yenguruve.
• Bidirectional Flow: Inokodzera kuyerera mune chero nzira.
• Rising Stem: Hunde inosimuka sezvo vharuvhu inovhurwa, ichipa chiratidzo chakajeka chekuona nzvimbo yevharuvhu.
• Metal-to-Metal Kuisa Chisimbiso: Kazhinji inoshandisa wedge uye mhete dzechigaro dzakaoma-kutarisana (semuenzaniso, neStellite) pakukukurwa uye kusapfeka.
• Kuvaka Kwakasimba: Yakagadzirirwa kubata kumanikidza kwakanyanya uye masimba, zvichikonzera muviri unorema uye wakasimba, kazhinji kubva kukanda kana simbi yekunyepedzera.

2. Zvikamu Zvikuru

1. Muviri: Chimiro chikuru chine dzvinyiriro, chinowanzo gadzirwa kubva kuCarbon Steel (WCB) kana Stainless Steel (CF8M/316SS). Migumo ine mitsetse (semuenzaniso, PN25/ASME B16.5 Kirasi 150) ndeye chiyero cheDN400.
2. Bonnet: Yakasungirirwa kumuviri, inogara hunde uye inopa muganho wekumanikidza. Kazhinji bhoneti yakawedzerwa inoshandiswa kune zvinangwa zvekudzivirira.
3. Wedge (Gedhi): Kiyi yekuisa chisimbiso chikamu. Kune PN25, Flexible Wedge yakajairika. Iyo ine kucheka kana groove yakatenderedza perimeter yayo inobvumira wedge kuchinjika zvishoma, kunatsiridza chisimbiso uye kubhadhara kudiki shanduko mukurongeka kwechigaro nekuda kwekuwedzera kwekupisa kana kushushikana kwepombi.
4. Stem: Iyo yakakwirira-yakasimba yakarukwa shaft (semuenzaniso, SS420 kana 17-4PH Stainless Steel) inoendesa simba kubva kune actuator kuenda kune wedge.
5. Zvindori zveSeat: Mhete dzakaomarara dzakadzvanywa kana kusungirirwa mukati memuviri unovharirwa newedge. Vanogadzira kuvharika kwakasimba.
6. Packing: Chisimbiso (kazhinji graphite yekushisa kwepamusoro) yakatenderedza hunde, iri mubhokisi rekuisa, kudzivirira kuvuza kune zvakatipoteredza.
7. Hydraulic Actuator: Piston-style kana scotch yoke actuator inofambiswa ne hydraulic pressure (kazhinji mafuta). Inopa iyo yakakwira torque / thrust inodiwa kuti ishandise hombe yeDN400 vharafu inopesana nehupamhi hwekusiyanisa kudzvanywa.

3. Kushanda Nheyo

• Kuvhura: Hydraulic fluid inoiswa mukati meiyo actuator, ichifambisa piston. Kufamba uku kunoshandurwa kuita rotary (scotch yoke) kana linear (linear piston) kufamba kunotenderedza hunde yevharuvhu. Dzinde rinopinda muweji, richiisimudza zvachose mubhoneti, isingavharidzi nzira yekuyerera.
• Kuvhara: Hydraulic fluid inotakurwa kune yakatarisana neiyo actuator, ichidzoreredza mafambiro. Dzinde rinotenderera uye rinosaidzira wedge pasi munzvimbo yakavharwa, iyo inotsikirirwa zvakasimba pamarin'i maviri ezvigaro, zvichiita chisimbiso.

Chirevo Chinokosha: Iri vharuvhu rakagadzirirwa kuzviparadzanisa (rakavhurika zvizere kana kuvharwa zvizere). Iyo haifanirwe kushandiswa kupuruzira kana kuyerera kwekudzora, sezvo izvi zvichizokonzera kudengenyeka, cavitation, uye nekukurumidza kukukurwa kweweji uye zvigaro.

4. Typical Applications

Nekuda kwehukuru hwayo uye chiyero chekumanikidza, iyi valve inoshandiswa mukuda maindasitiri maapplication:

• Mvura Yekufambisa & Kugovera Mains: Kuparadzanisa zvikamu zvemapaipi makuru.
• Power Plants: Kutonhora kwemvura masisitimu, mitsetse yemvura yekudyisa.
• Industrial Process Mvura: Zvikuru-zvikuru zveindasitiri.
• Desalination Plants: High-pressure reverse osmosis (RO) mitsetse.
• Migodhi uye Zvicherwa Kugadziriswa: Mapaipi anotsvedza (ane kusarudzwa kwezvinhu zvakakodzera).

5. Zvakanakira uye Zvakaipa

6. Hunhu Hunokosha Pakusarudza uye Kushandisa

• Kusarudzwa Kwezvinhu: Match body/wedge/seat materials (WCB, WC6, CF8M, etc.) kune fluid service (mvura, corrosivity, tembiricha).
• Kugumisa Kubatana: Ita shuwa flange zviyero uye yakatarisana (RF, RTJ) inofananidza pombi.
• Hydraulic Power Unit (HPU): Ivhavha inoda HPU yakasiyana kuti ibudise hydraulic pressure. Funga nezve inodiwa yekushanda kumhanya, kudzvanywa, uye kutonga (yemunharaunda / kure).
• Fail-Safe Mode: The actuator inogona kutaurwa seFail-Open (FO), Fail-Closed (FC), kana Fail-in-Last-Position (FL) zvichienderana nekuchengetedza zvinodiwa.
• By-Pass Valve: Pakushandisa kwepamusoro-kudzvanya, diki by-pass valve (eg, DN50) inowanzoiswa kuti ienzane kudzvanywa kwepakati pechete isati yavhura vharafu huru, ichidzikisa inodiwa yekushandisa torque.

Muchidimbu, Hydraulic Wedge Gate Valve DN400 PN25 ibasa repamusoro-soro, rinorema-basa rekumisa zvachose kana kutanga kuyerera kwemvura mumapaipi makuru, ane simba guru. Kushanda kwayo hydraulic kunoita kuti ive yakakodzera kure kana otomatiki yakakosha yekuzviparadzanisa mapoinzi.
