Newsway Valve Company (NSW) mavharuvhu anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana dzepombi, anogona kuita zvinotevera zvinodiwa pombi mavharuvhu

1. Cheka uye usunungure svikiro

Iri ndiro basa rinonyanya kukosha revhavha. Kazhinji, valve ine nzira yakananga-kuyerera inosarudzwa, uye kuyerera kwayo kunopesana kuduku.

Mavharuvhu akavharwa pasi (Globe mavharuvhu, Plunger mavharuvhu) haawanzo shandiswa nekuda kwemavharuvhu awo anoyerera uye akakwira kuyerera kwekudzivirira kupfuura mamwe mavharuvhu. Apo kupikisa kwepamusoro kunobvumirwa, valve yakavharwa inogona kushandiswa.

2. Control flow

Kazhinji, vharuvhu iri nyore kugadzirisa kuyerera inosarudzwa sekutonga kuyerera. Ivhavha yekuvhara yakadzika (yakadai seaglobe valve) inokodzera chinangwa ichi nekuti saizi yechigaro chayo inoenderana nekurova kwenhengo inovhara.

Rotary mavharuvhu (Plug mavharuvhu, butterfly valves, bhora mavharuvhu) uye flex-body mavharuvhu (pinch mavharuvhu, diaphragm mavharuvhu) anogonawo kushandiswa throttling control, asi anowanzo shanda chete mukati mechikamu chidiki chemadhayamita evharuvhu.

Ivhavhavha yegedhi inoshandisa gedhi rakaita sedhisiki kuita kuchinjika-kucheka mafambiro kune denderedzwa revharu chigaro kuvhura. Inogona kudzora kuyerera zvakanaka chete kana iri pedyo nenzvimbo yakavharwa, saka kazhinji haishandiswe pakuyerera kwekudzora.

3. Kudzokera shure uye shunting

Zvinoenderana nezvinodiwa zvekudzosera kumashure uye shunting, rudzi urwu rwevharuvhu runogona kuve nematanho matatu kana anopfuura. Plug mavharuvhu uye3 nzira bhora mavharuvhudzakanyanya kukodzera chinangwa ichi. Naizvozvo, mavharuvhu mazhinji anoshandiswa kudzosera kumashure nekuparadzanisa kuyerera anosarudza imwe yeaya mavharuvhu.

Asi mune zvimwe zviitiko, mamwe marudzi emavharuvhu anogona zvakare kushandiswa kudzoreredza uye shunting chero maviri kana anopfuura mavharuvhu akanyatsobatanidzwa kune mumwe nemumwe.

4. Pakati nepakati nezvidimbu zvakaturikwa

Kana pane zvakaturikwa zvimedu mukati, inonyanya kukodzera kushandisa vheji ine mhedzisiro yekupukuta painotsvedza yenhengo yekuvhara pamwe chete nechiso chekuvhara.

Kana kuseri uye mberi kufamba kwenhengo yekuvhara kuchigaro chevharuvhu kwakamira, inogona kubata zvimedu. Naizvozvo, vharuvhu iyi inongokodzera zvekutanga zvakachena midhiya kunze kwekunge iyo yekuvharisa pamusoro pezvinhu ichibvumira kuti zvimedu zvipinzwe. Mavharuvhu ebhora uye mavharuvhu epuragi ane mhedzisiro yekupukuta pachisimbiso chepamusoro panguva yekuvhura nekuvhara maitiro, saka akakodzera kushandiswa mune midhiya ine yakaturikwa zvimedu.
