Valve yeButterfly yeKubvisa Katatu

Vharuvhu yeButterfly yeKubvisa Katatu: Ongororo Yechigadzirwa Yakakwana

Chii chinonzi Triple Offset Butterfly Valve

A vharuvhu yeshavishavi ine mativi matatu(TOBV) ivharuvhu yeindasitiri inoshanda zvakanyanya yakagadzirirwa kudzora kuyerera kwemvura nemazvo mukushandiswa kwakaoma. Maitiro ayo akasiyana anoderedza kupera, anovimbisa kuvharwa kwakasimba, uye anoshanda zvinobudirira mumamiriro ekunze ekudziya kwakanyanya uye kumanikidzwa. Kusiyana neyakajairika.mavharuvhu eshavishaviTOBV inoshandisadhizaini ye eccentric katatukubvisa kukweshana pakati pedhisiki nechigaro panguva yekushanda, zvichiita kuti ive yakakodzera mabasa akakosha.

Kunzwisisa Dhizaini ye "Triple Offset"

Izwi rekuti "triple offset" rinoreva ma "geometric offsets" matatu akasiyana mukugadzirwa kwevharuvhu:

1. Kurasikirwa Kwekutanga: Mubato wevharuvhu uri kumashure kwemutsetse wepakati pechigaro, zvichiita kuti dhisiki ikwanise kutenderera isina kubata chigaro.

2. Kurasikirwa Kwechipiri: Mugodhi wacho wakadzikira kubva pakati pepombi, zvichiita kuti pave nekufamba kwakafanana nekamera kuti pave nekushanda zvakanaka.

3. Kurasikirwa Kwechitatu: Nzvimbo yechigaro yakakombama (conical profile), zvichiita kuti pave ne wedging effect inowedzera kuvharika kwevharuvhu painovhara.

Dhizaini iyi inobvisa kukweshana kunotsvedza, inoderedza kupera, uye inovimbisa kusabuda kwemvura kunyangwe mushure mekushandisa kwenguva refu.

Magadzirirwo Akakosha

Saizi dzeVharuvhu

- Rudzi Rwakajairika:2" kusvika 48" (DN50 kusvika DN1200).

Kuongororwa kweDzvinyiriro

- Makirasi eANSI: 150 kusvika 600.

- Kuongororwa kwePN: PN16 kusvika PN100.

- Yakakodzera masisitimu ane simba repamusoro rinosvika 1,450 psi (100 bar).

Mhando dzekubatanidza

- Yakaputirwa:ANSI, DIN, kana JIS standard flanges.

- Wafer/Lug:Dhizaini diki yekuisa nzvimbo shoma.

- Kusundira Matako:Kune masisitimu emapaipi anogara aripo uye akasimba.

Zvinhu

- Muviri/Kuchekwa:Simbi isina ngura (SS316, SS304), simbi mbiri, simbi yekabhoni, Inconel®, Hastelloy®.

- Chigaro:Zvisimbiso zvesimbi zvinogara kwenguva refu kana zvinhu zvakasanganiswa (semuenzaniso, graphite + simbi isingasvibi).

- Dhisiki:Kazhinji yakafukidzwa ne stellite kana ceramic kudzivirira kukwesha.

Mamiriro Ekushanda

- Kureba kweTembiricha:-196°C kusvika 850°C (-320°F kusvika 1,562°F).

- Midhiya:Inoenderana neutsi, mahydrocarbon, makemikari anoparadza, uye mvura dzinopisa.

- Maindasitiri:Oiri negasi, kugadzira magetsi, kugadzirisa makemikari, LNG, uye zvemugungwa.

Mabhenefiti eMavharuvhu EmaButterfly Ane Katatu

1. Kusabuda Kwemvura:Dhizaini ine zvigaro zvesimbi inoenderana neISO 5208 Leakage Class A (inodzvinyirirwa nemabubble).

2. Hupenyu Hurefu hweBasa:Kusakweshana kunoita kuti pasave nekusakara kwakanyanya, kunyangwe mushure mezviuru zvemadenderedzwa.

3. Kugadziriswa Kwakaderera:Hapana mafuta ekuisa kana kutsiva chigaro nguva dzose.

4. Kuchinja-chinja:Inogona kuchinjwa kana tembiricha yakanyanyisa, kumanikidzwa, uye zvinhu zvinoparadza.

Mashandisirwo

- Nzvimbo dzekuchenesa mafuta:Kuparadzanisa uye kutonga mafuta asina kucheneswa, gasi, uye zvigadzirwa zvakanatswa.

- Mafekitori emagetsi:Kubviswa kwemhepo inopfungaira mumaturbine nemaboilers.

- Zvirimwa zveMakemikari:Kubata maasidhi, alkali, uye mvura inokasira.

- Masisitimu eCryogenic:Kuchengetera nekutakura LNG.

Kutevedzera Mutemo & Zvitupa

- Mitemo:API 609, ASME B16.34, ISO 5752.

- Dhizaini Inodzivirira Moto:InotevedzeraAPI 607/API 6FAzvekushandisa zvisingatsvi.

Vharuvhu yemhando ye "triple offset butterfly" inosanganisa mainjiniya ekugadzira zvinhu nemazvo nezvinhu zvakasimba kuti ipe kuvimbika kusingaenzaniswi mumabasa akakosha emaindasitiri. Dhizaini yayo yepamusoro inotarisa zvipingamupinyi zvemavharuvhu echinyakare, zvichiita kuti ive sarudzo inofarirwa kune masisitimu emazuva ano anoshanda zvakanyanya.
