Zvakanakira uye zvakaipira kusarudzwa kwegedhi valve

Pakati pemhando dzakasiyana-siyana dzevhavha,gedhi mavharuvhundiwo anonyanya kushandiswa.Varuvhu (gedhi) zvinoreva vharuvhu ine ndiro yegedhi inofamba ichienda kwakatwasuka kweakisi yechaneli.Inonyanya kushandiswa kucheka svikiro pane pombi, kureva, kuvhurika zvakakwana kana kuvharwa zvizere.Kazhinji, mavharuvhu emagedhi haagone kushandiswa sekupuruzira.Inogona kushandiswa kwepamusoro tembiricha uye yakanyanya kudzvanywa, uye inogona kushandiswa kune akasiyana siyana midhiya.Mavharuvhu egedhi haawanzo shandiswa mumapaipi anotakura madhaka uye zvinwiwa zveviscous.

Ivhavha yegedhi ine zvinotevera zvakanakira:

1. Kuramba kwemvura kudiki;

2. Torque inodiwa pakuvhura nekuvhara idiki;

3. Inogona kushandiswa pane ring network pipeline apo iyo yepakati inoyerera mumativi maviri, kureva, kuyerera kwepakati hakubvumirwi;

4. Kana yakanyatsozaruka, kukukurwa kwenzvimbo yekuvharisa nesvikiro rekushanda idiki pane yevharuvhu;

5. Chimiro chacho chiri nyore uye nzira yekugadzira iri nani;

6. Kureba kwechimiro kuduku.

Nokuti mavharuvhu emagedhi ane zvakawanda zvakanakira, anoshandiswa zvakanyanya.Kazhinji, pombi ine saizi yezita ≥ DN50 inoshandiswa semudziyo wekucheka pakati, uye kunyangwe pane mamwe madiki-diameter mapaipi (akadai seDN15~DN40), mamwe mavharuvhu egedhi achiri akachengetwa.

Mavharuvhu egedhi anewo zvimwe zvisingabatsiri, kunyanya:

1. Izvo zviyero zvose uye kureba kwekuvhura zvakakura, uye nzvimbo inodiwa yekuisa zvakare yakakura.

2. Panguva yekuvhura nekuvhara, pane kukakavara pakati pezvisimbiso zvekuvhara, uye kupfeka kwakakura, uye zviri nyore kukonzera scratches.

3. Kazhinji, mavhavha emagedhi ane maviri ekuvhara chisimbiso, izvo zvinowedzera mamwe matambudziko pakugadzirisa, kugaya nekugadzirisa.

4. Nguva yekuvhura nekuvhara yakareba.
