Valve yeGate reRising Stem vs Non Rising Stem: Kusiyana Kwakakosha & Mashandisirwo Emaindasitiri
Kuronga Magadzirirwo eVharuvhu yeGedhi
Mavharuvhu egedhi anorongwa zvichienderana nekugadzirwa kwehunde:Mavharuvhu eGedhi reSimbi Rinokwira(OS&Y) uye Mavharuvhu Egedhi Asiri Kukwira. Rudzi rumwe nerumwe rune zvakanakira zvakasiyana zvekuvaka kudzora kuyerera kwemvura mumaindasitiri.
Chii chinonzi Rising Stem Gate Valve
Magadzirirwo ehunde anokwira anoisa hunde pamusoro pemuviri wevharuvhu. Kutenderera hunde kunosimudza/kudzikisa gedhi, zvichiita kuti:
Zviratidzo zveChinzvimbo cheMuviri:Kureba kwehunde kunoratidza mamiriro ekuvhura/kuvhara panguva chaiyo.
Kugadzirisa Kuri Nyore: Tambo dzakaratidzwa dzinoita kuti mafuta arambe achinyoroveswa (zvichipa nguva yakareba yekushanda).
Kugara Kwakasimba: Hunde haibatanidzi mvura, yakakodzera kushandiswa kwezvinhu zvinoparadza (semuenzaniso, mafuta, makemikari).
Mashandisirwo: Zvivakwa zvePetrochemical, kurapwa nemvura, kuiswa pamusoro pevhu.
Chii chinonziValve yeGedhi Risingakwiri
Madzinde asingasimuki ane nzungu yemukati iri mukati memuviri wevharuvhu. Kutenderera kunofambisa gedhi uku dzinde richiramba rakamira:
Kushanda Nesimba Munzvimbo: Kureba kwakabatana (kunochengetedza nzvimbo yakatwasuka ye30–50% zvichienzaniswa nemadzinde ari kukwira).
Kuramba Kuora: Dhizaini yakavharwa inodzivirira kubva kuguruva/kukukurwa kwevhu.
Kuchinjika Kwekuisa: Yakanakira nzvimbo dzakamanikana (semuenzaniso, mapaipi, ngarava, masisitimu emakanzuru).
Cherechedza: Shinda dzemukati dzinoda mafuta anozorwa nguva nenguva; zviratidzo zvekuvhura zvakakosha.
Misiyano mikuru: Mavharuvhu eRising Stem Gate vs Non Rising Stem Gate
| Chinhu | Valve yeGedhi reSimbi Richikwira | Valve yeGedhi Risingakwiri |
|---|---|---|
| Dhizaini | Shinda dzetrapezoidal dzakaratidzwa | Shinda dzemukati dzemukati |
| Kufamba kweHunde | Chikwidzo chakamira chine gedhi | Inotenderera panzvimbo |
| Kudiwa Kwenzvimbo | Yakakwirira (1.2x dhayamita yevharuvhu) | Kapfupi |
| Kugadzirisa | Kuisa mafuta zviri nyore uye kuongorora | Zvakaoma; zvinoda kupatsanurwa |
| Hupenyu Hwese (Matenderedzwa) | 100,000+ | ~50,000 |
| Zvakanakira | Kushanda kakawanda, ngura yakawanda | Masisitimu akavharirwa nzvimbo, akavharirwa |
Nhungamiro dzeKushanda & Kusarudza
1. Zvipingamupinyi zveMunda
Mavharuvhu esimbi asingakwiri anoderedza kukwirira ne30–50% kumavharuvhu >DN300.
2. Kuenderana Kwepakati
Zvinonhuwirira zvinoparadza here? Sarudza mavharuvhu anokwira ane SS316L stems (40%+ resistance corrosive).
3. Kuwanda Kwekushanda
Madzinde anokura anogara kwenguva refu kaviri (100k vs. 50k).
4. Dhizaini Yakakosha
- Kusakwira neMakomba Ekutsaudzira:Inoderedza mvura inodonha (kuderera kwesimba remhepo ne15–20%).
- Matavi Anokwira eElastic Seal:Zvisimbiso zvePTFE zvinozadzisa mwero wekubuda kwemvura weANSI Class VI kune masisitimu egasi.
5. Kutevedzera Mitemo:
- Madzinde anokura:API 600 (simba rekudhonza remudzi ≥483 MPa).
- Madzinde asingasimuki:Kuyedzwa kwechisimbiso cheshinda cheISO 7-1.
Mhedziso: Kufananidza Valve neKushandiswa
Mavharuvhu egedhi rinokwira anonyanya kukosha pakuwana nzira yekugadzirisa uye maonero ekuona, nepo mavharuvhu egedhi asina kukwira achibudirira munzvimbo dzakamanikana. Mainjiniya anofanira kuyera zvinotevera:
- Zvinodiwa pakugadzirisa (kuwedzera kwekubatsira kwemuti)
- Nzvimbo yekuisa (haisi tsime rinokwira)
- Zvinodiwa zveMedia & Mashandiro
Gadzirisa masisitimu ekudzora kuyerera kwemvura nhasi nekusarudza dhizaini yemavharuvhu egedhi akakodzera nzvimbo yako yeindasitiri.
