Parallel Slide Gate Valve: Gwaro Rekupedzisira reZvimiro, Mhando & Mashandisirwo

Chii chinonzi Parallel Slide Gate Valve

Parallel Slide Gate Valve ivharuvhu inotsvedza inodzora kuvhura/kuvhara kuburikidza nemadiski egedhi akafanana. Chikamu chayo chekuvharira (gate disc) chine nzvimbo dzakakwenenzverwa uye dzakati sandara dzinobatana zvakasimba nechigaro, dzinoshandiswa zvakanyanya kudzima kana kubatanidza kuyerera kwemagetsi.

Nheyo yekushanda

Vharuvhu yegedhi rinotenderera rinotenderera rinoshandisa chimiro chedhisiki mbiri. Nzira yekufambisa inofambisa gedhi yakatwasuka kuti ivhure/ivhare nzira yemvura. Gedhi rine bhora rakaenzana nedhayamita yemukati yepombi. Kutenderera vhiri reruoko kana kuvhura actuator kunosimudza/kudzikisa tsinde negedhi. Kana bhora regedhi rakabatana nepaipi, mvura inoyerera (vharuvhu inovhurika). Kana gedhi ravhara nzira yemvura (bhora rakadzoserwa mukamuri revharuvhu), vharuvhu rinovhara.

Zvikamu Zvikuru zveParallel Slide Gate Valve

Valve Muviri & Gedhi Disc

Muviri wacho wakagadzirwa kana kugadzirwa nesimbi yekabhoni, simbi isingatsvi, nezvimwewo, une madhisiki egedhi akafanana. Dhizaini yemadhisiki maviri inovandudza kuvharwa. Kufamba kwemadhisiki akamira kunodzora kuyerera.

Hunde & Kuisa Chisimbiso

Hunde yacho (simbi isina ngura/simbi isina ngura) inobatanidza negedhi kuburikidza neshinda. Zvikamu zvekuvhara zvinosanganisira zvigaro zvesimbi zvine mativi akasimba, PTFE, kana graphite rings zvinovimbisa kuvhara kwemativi maviri.

Muchina wekutyaira

MaActuator anotevedzera mitemo yeAPI 6D, anotsigira mashandiro emaoko, emagetsi, kana emhepo. Pane sarudzo dzisingaputike.

Chisimbiso Chekuvaka

Ine zvigaro zvinoyangarara zvine pre-loading kuti zvivharwe nemativi maviri. Zvinhu: graphite yakasimbiswa, PTFE.

Zvimwe Zvikamu Zvakakosha

Joke Sleeve: Aluminium bronze inoderedza torque yekushanda.

Mhete Yechigaro: Yakasungirirwa kuti igare iri nyore kugadzirisa.

Mavharuvhu eGedhi reSiridhi Rinofefeterwa Nemhepo kana kuti Risina Kufefeterwa Nemhepo

Kusiyana kukuru kuri muchimiro, mashandiro, uye mashandisirwo. Mavharuvhu ane mhepo ane buri rekuderedza kumanikidzwa, kupinza vhu, uye dziviriro yezvigaro mumapaipi marefu. Mavharuvhu asina mhepo anokodzera masisitimu akavharwa asina zvinodiwa zvekuvhara vhuru.

Kusiyana Kwemaumbirwo Uye Mashandiro

• Dhizaini yeMaburi Emhepo:

Yakavhurika:Buri (rakaenzana nehukuru hwepamusoro) mudhisiki repasi. Rakavhurika zvizere = buri rinoenderana nechigaro chekuderedza kuyerera/kumanikidzwa.

Isina Kuburitsa Mamhepo:Hapana buri. Mugero wechigaro unoiswa pachena kana wakavhurika.

• Dziviriro yeChisimbiso:

Yakavhurika:Buri rinodzivirira zvigaro kubva mukukukurwa kwenzvimbo dzakananga, zvichiita kuti hupenyu hurambe huchireba.

Isina Kuburitsa Mamhepo:Zvigaro zvinogona kukweshera kana zvakavhurika; kuvimbika kwakaderera.

Maitiro Ekushandisa

Zvakanakira Kushanda

•Kuderedza Kumanikidzwa: Kunoburitsa mweya wekumanikidzwa kwemugomba uri pamusoro pemvura, zvichidzivirira kumanikidzwa kwakanyanya kubva pakupararira kwenzvimbo.

•Kushanda Nesimba Kwemvura: Kuderera kwesimba remhepo kwakaderera nenzira yakatsetseka yekuyerera kwemvura (yakanakira mafuta asina kucheneswa, gasi rechisikigo).

•Kugadzirisa: Kugadzira nguruve kunobvisa marara epombi, zvichideredza nguva yekushanda.

Zvimiro zveMaumbirwo

•Chisimbiso: Zvisimbiso zveO-ring + zvigaro zvinoyangarara zvakatoiswa kare zvinogonesa kuvharwa kwemativi maviri. Torque yekushanda yakaderera ne50% pane mavharuvhu akajairwa.

•Maumbirwo Ekuisa Packing: Kuisa pack yega kunoda kugadziriswa kushoma. Kushanda kwakareruka uye kuvharwa kwakavimbika. Kuisa mafuta ekuwedzera kunoita kuti pasave nekubuda mvura.

•Kugadzirwa kweNzira Yekuyerera: Nzira yekuyerera yakazara yakatwasuka inoderedza kurasikirwa kwekumanikidzwa. Inotsigira kukwira kwepombi.

•Dziviriro: Chivako chakavharwa zvizere kuti chishande mumamiriro ekunze ese.

•Mudziyo Wekuderedza Kumanikidzwa: Unodzivirira kukuvara kwemukati memuviri.

•Kupatsanura:

NeDrive:Maoko, Pneumatic, Magetsi.

Nebasa:Inofefetera, Isina Kufefetera, Nzvimbo yeOiri, Mapaipi, Gasi.

Minda Yekushandisa

→Oiri neGasi: Mainline valves ekutumira gasi risina kucheneswa/rechisikigo (kusvika ku15.0MPa). Inoshandiswa mumasystem ekubvisa gasi nekuchengetedza. Inoenderana neAPI 6D.

→Indasitiri yeMakemikoro: Inodzora zvinhu zvinoparadza (acids, slurry) ichishandisa PTFE/graphite seals.

→Indasitiri yeMagetsi: Inotarisira kuyerera kwemvura inotonhorera/mhepo muzviteshi zvinopisa, zvenyukireya uye zvemvura. Inowedzera kushanda zvakanaka kwesimba.

→Manispa & Zvakatipoteredza: Inodzora mvura/gasi rakasviba muhurongwa hwekuchenesa/kuburitsa mvura. Inoshandiswa mukupa mvura/kudhonza mvura.

→Mamwe Maindasitiri: Kutamiswa kwesimbi kwakachena zvakanyanya (simbi), kupatsanurwa kwemidziyo isina tsvina (mishonga), kudzora mvura yakachena (chikafu).

Zvakanakira & Zvakashata

Zvakanakira

1. Kuramba Kuyerera Kwakaderera: Dhizaini yakatwasuka yakazara ≈ kuramba kwechikamu chepombi pfupi. Kukwanisa kuyerera kwakawanda.

2. Kuvhara Kwakanaka Kwazvo: Madhisiki anovhara kaviri (simbi + zvigaro zvakapfava) anoita kuti avharwe zvakanaka. Anobata kushanduka-shanduka kwedzvinyiriro/tembiricha.

3. Maumbirwo Ari Nyore: Kugadzira & Kugadzirisa Kuri Nyore. Mutengo wakaderera wehupenyu.

4. Kusapfeka Zvigaro: Zvigaro zvakasimba zvinowedzera hupenyu hwebasa kana zvikashandiswa zvinokwenya.

5. Kushandiswa Kwakafara: Inokodzera nzvimbo dzakasiyana-siyana (-196°C cryogenic kusvika +550°C steam) - crude, gasi, acids, slurry.

6. Torque Inoshanda Zvishoma: Kushanda nemaoko nyore nyore.

7. Kuvhara mativi maviri: Kuchengetedza kuti mvura isadonhe.

Zvakashata

1. Hazvishandiswe pakupinza mvura mumhepo: Zvinongoitwa pabasa reKUVHARA/KUDZIMA chete. Kuvhura zvishoma kunokuvadza zvigaro.

2. Kusagona Kudzora Kuyerera Kwemvura: Kudzora kuyerera kwemvura zvinobudirira chete panzvimbo yakavhurika inosvika 50%.

3. Kudedera kweDisiki: Kunowanzo tetepa kana ichivhara ichipesana nekuyerera kwemhepo ine simba/kurema.

Nhungamiro dzeSarudzo

1. Kuenderana kweMedia: Unganidza vharuvhu nemedia. Semuenzaniso:

• Acids/Alkalis → Simbi isina ngura / PTFE-yakafukidzwa.

• Madonhwe emvura anoputika → Dhisiki rakaputirwa neTungsten carbide.

• Basa reCryogenic → Simbisa kusimba kwezvinhu pakupisa kwakaderera.

2. Kumanikidzwa uye Tembiricha: Ita shuwa kuti chiyero chevharuvhu chinofukidza mamiriro ekushanda:

• Kirasi 150: -29°C kusvika 425°C

• Kirasi 600: -196°C kusvika 550°C

• Kirasi 1500: -29°C kusvika 650°C

3. Rudzi rweMaumbirwo:

• Hunde Inokura:Kuti zvikwanise kushandiswa nguva nenguva/kuvhiyiwa kwenguruve.

• Hunde Isina Kukwira:Kune nzvimbo isingawanzo shandiswa/nzvimbo diki.

4. Nzira yekushanda: Mamwe maParameter: Funga nezveCv (kuyerera kwehuwandu), kirasi yekudonha kwemvura, mukana wekugadzirisa, uye zvinodiwa pakushanda.

• Nemaoko: Mavharuvhu madiki kana kuti backup.

• Magetsi/Pneumatic: Mavharuvhu makuru (DN300+).

• Nzvimbo Dzinoputika → Pneumatic/Hydraulic kana kuti magetsi asingaputike.

• Mavharuvhu emaoko: Wedzera gearbox kuti torque yakakwira.
