Vharuvhu yegedhi reHydraulic wedge DN400 PN25

1. Tsananguro uye Zvinhu Zvikuru

Vharuvhu yeHydraulic Wedge Gate ivharuvhu yekufamba ine mutsara apo dhisiki (gedhi) rakaita sewedge rinosimudzwa kana kudzikiswa ne hydraulic actuator kudzora kuyerera kwemvura.

Zvinhu Zvikuru zvehukuru uhwu nekirasi iyi:

• Dhizaini yeBore Rakazara: Dhayamita yemukati inoenderana nepombi (DN400), zvichikonzera kudzikira kwedzvinyiriro kwakaderera zvikuru kana yakavhurika zvizere uye zvichibvumira kukwira kwepombi.
• Kuyerera kwenzira mbiri: Kwakakodzera kuyerera kwenzira mbiri.
• Hunde Inokwira: Hunde inokwira sezvo vharuvhu inovhurwa, zvichiratidza zvakajeka nzvimbo yevharuvhu.
• Kuvhara Simbi: Kazhinji inoshandisa mhete dzechigaro dzakaomarara (semuenzaniso, neStellite) kuti dzisaparare uye dzisaparare.
• Kuvaka Kwakasimba: Kwakagadzirwa kuti kugone kudzvinyirirwa zvakanyanya, zvichikonzera muviri unorema uye wakasimba, kazhinji wakagadzirwa nesimbi yakaumbwa kana yakagadzirwa.

2. Zvikamu Zvikuru

1. Muviri: Chimiro chikuru chine simba rekumanikidzwa, chinowanzogadzirwa neCarbon Steel (WCB) kana Stainless Steel (CF8M/316SS). Migumo yakakombama (semuenzaniso, PN25/ASME B16.5 Class 150) ndiyo yakajairika yeDN400.
2. Bhoniti: Yakasungirirwa pabhaudhi, inochengetedza hunde uye inopa muganhu wekumanikidzwa. Kazhinji bhoniti refu rinoshandiswa kudzivirira kupisa.
3. Wedge (Gedhi): Chikamu chekiyi yekuvhara. Kune PN25, Flexible Wedge yakajairika. Ine kucheka kana goko rakatenderedza miganhu yayo rinobvumira wedge kugonya zvishoma, zvichivandudza kuvharwa uye zvichitsiva shanduko diki pakurongeka kwechigaro nekuda kwekuwedzera kwekupisa kana kumanikidzwa kwepombi.
4. Hunde: Mugodhi une shinda yakasimba (semuenzaniso, SS420 kana 17-4PH Stainless Steel) unotumira simba kubva kuactuator kuenda ku wedge.
5. Mhete dzeChigaro: Mhete dzakasimba dzakadzvanywa kana kusungirirwa mumuviri unovhara wedge. Dzinoita kuti dzivharwe zvakasimba.
6. Kurongedza: Chisimbiso (kazhinji girafiti yekupisa kwakanyanya) chakakomberedza hunde, chiri mubhokisi rekuputira, kudzivirira kubuda kwemvura munzvimbo.
7. Hydraulic Actuator: Chishandiso chepiston kana kuti scotch yoke chinofambiswa ne hydraulic pressure (kazhinji mafuta). Chinopa torque/thrust yakakwira inodiwa kuti vharuvhu hombe yeDN400 ishande ichirwisa high differential pressure.

3. Nheyo yekushanda

• Kuvhura: Mvura yeHydraulic inoiswa mu actuator, ichifambisa piston. Kufamba uku kunoshandurwa kuita kufamba kwe rotary (scotch yoke) kana linear (linear piston) kunotenderera tsinde yevharuvhu. Tsinde rinopinda mu wedge, richiisimudza zvachose mubhoneti, risingavharidzi nzira yekuyerera.
• Kuvhara: Mvura ye hydraulic inonamirwa kune rimwe divi re actuator, ichidzosera kumashure kufamba. Dumbu rinotenderera uye rinosundira wedge pasi panzvimbo yakavharwa, uko rinodzvanywa zvakasimba pamaringi maviri echigaro, zvichiita kuti pave nechisimbiso.

Zvakakosha: Vharuvhu iyi yakagadzirirwa kuvharwa (yakavhurika zvizere kana kuvharwa zvizere). Haifanirwe kushandiswa kudzora kuyerera kwemvura, sezvo izvi zvichikonzera kudedera, kuvhurika kwemukati, uye kukurumidza kudonha kwechikamu chezvigaro.

4. Mashandisirwo Akajairika

Nekuda kwehukuru hwayo uye kumanikidzwa kwayo, vharuvhu iyi inoshandiswa mumaindasitiri anoda kushanda zvakanyanya:

• Mapombi Ekufambisa Mvura Nekugovera: Kuparadzanisa zvikamu zvemapaipi makuru.
• Mafekitori emagetsi: Masisitimu emvura anotonhodza, mitsetse yemvura inoyerera.
• Mvura yeMaindasitiri: Mafekitori makuru emaindasitiri.
• Miti yekubvisa munyu: Mitsetse ye reverse osmosis (RO) ine simba guru.
• Kuchera nekugadzira zvicherwa: Mapaipi eSlurry (ane sarudzo yakakodzera yezvinhu).

5. Zvakanakira Nezvakaipa

6. Zvinhu Zvakakosha Kufunga Nezvekusarudza Nekushandisa

• Sarudzo Yezvinhu: Gadzirai zvinhu zvemuviri/wedge/zvigaro (WCB, WC6, CF8M, nezvimwewo) zvichienderana nesevhisi yemvura (mvura, ngura, tembiricha).
• Kubatana Kwemagumo: Iva nechokwadi chekuti mwero weflange uye kutarisa (RF, RTJ) zvinoenderana nepaipi.
• Hydraulic Power Unit (HPU): Vharuvhu inoda HPU yakasiyana kuti igadzire hydraulic pressure. Funga nezvekumhanya kunodiwa pakushanda, pressure, uye control (yemuno/iri kure).
• Nzira Yakachengeteka Yekutadza: Chinokonzeresa chinogona kutaurwa sekuti Fail-Open (FO), Fail-Closed (FC), kana Fail-in-Last-Position (FL) zvichienderana nezvinodiwa zvekuchengetedza.
• Vharuvhu Inopinda Nesimba: Pakushandisa simba rine simba rakawanda, vharuvhu diki (semuenzaniso, DN50) inowanzoiswa kuti ienzanise simba riri pakati pevharuvhu huru isati yavhurwa, zvichideredza simba rinodiwa rekushanda.

Muchidimbu, Hydraulic Wedge Gate Valve DN400 PN25 ibasa guru, rinorema rekumisa kana kutanga kuyerera kwemvura mumapaipi makuru ane simba guru. Kushanda kwayo kwe hydraulic kunoita kuti ive yakakodzera nzvimbo dziri kure kana dzinozvishandira dzega.
