Semugadziri anotungamira wemhando yepamusoro mavharuvhu, ZFA inowanzogashira mibvunzo nezve mutsauko pakati pemhando dzakasiyana dzevharuvhu. Mubvunzo wakajairika ndewekuti: Ndeupi mutsauko pakati peabutterfly valveuye abutterfly cheki vharafu? Kunyange vachigovana mazita akafanana uye vese vachishandisa disc-mhando dhizaini, mabasa avo, mashandisiro, uye mashandisiro akasiyana.
Gwaro iri rinotarisa kusiyana kukuru uku, richitora hunyanzvi hweZFA. Tichabata izvo zvekutanga-sekutsanangura, dhizaini, uye misimboti yekushandisa. Kunyangwe iwe uri mainjiniya, nyanzvi yekutenga zvinhu, kana nyanzvi yeindasitiri, chinyorwa ichi chichakubatsira iwe kuita sarudzo ine ruzivo.
1. Chii chinonzi Butterfly Valve?
Bhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha inotenderedza kota-turn rinonyanya kushandiswa kuyerera kuyerera kana kuzviparadzanisa mumapaipi. Iyo ine disc inotenderera nezve axis yepakati kuvhura kana kuvhara nzira yekuyerera.
1.1 Mashandiro eButterfly Valve
Ivhavha inoshanda nekutenderera disc 90 degrees: yakazaruka zvakakwana, ichibvumira kuyerera kusingabviri, kana kuvharwa, kuvhara nzira yekuyerera. Kutenderera kwechidimbu kunobvumira kupuruzira, zvichiita kuti ive yakakodzera kudzora kuyerera.
1.2 Zvishandiso zvakajairika
- Water Treatment Plants
- HVAC masisitimu
- Chemical Processing
- Chikafu uye Beverage Indasitiri
2. Chii chinonzi Butterfly Check Valve?
A butterfly cheki vharafu, inozivikanwawo sevhavha yekaviri-disc cheki, ivharuvhu isingadzoke kana imwe nzira vharafu inodzivirira kuyerera kwepaipi. Kusiyana neshavishavi mavharuvhu, anoshanda otomatiki pasina ekunze actuation.
2.1 Kushanda Nheyo
Kuyerera kwemberi kunosunda dhisiki kuvhurika, kukunda kushushikana kwechirimo. Kana kuyerera kunomira kana kudzoka, chitubu chinokurumidza kuvhara diski, ichigadzira chisimbiso chakasimba kudzivirira kudzoka. Uku otomatiki kushanda hakudi kupindira kwevanhu.
2.2 Zvishandiso zvakajairika
- Pombi Discharge Lines
- Compressor Systems
- Marine uye Offshore Platform
-Wastewater Management
3. Misiyano Yakakosha Pakati peButterfly Valves uye Butterfly Check mavharuvhu
Nepo vese vachishandisa disc mashini, yavo yakakosha mashandisirwo akasiyana. Heino kuenzanisa-ne-kurutivi:
| Aspect | Butterfly Valve | Butterfly Check Valve |
| Primary Function | Kuyerera kwemitemo uye kuzviparadzanisa nevamwe | Backflow kudzivirira |
| Operation | Manual kana actuated kutenderera | Otomatiki (yakaremerwa muchirimo) |
| Disc Design | Single disc pane shaft | Mahwendefa maviri ane hinges uye zvitubu |
| Flow Direction | Bidirectional (ine chisimbiso chakakodzera) | Unidirectional chete |
| Installation | Wafer, lug, kana flanged | Wafer, lug, kana flanged |
Tafura iyi inoratidza zvikonzero zvekusarudza imwe pane imwe: butterfly mavharuvhu ekudzora, tarisa mavharuvhu ekudzivirira.
6. Nyundo yemvura uye Speed yekupindura
Nyundo yemvura inowanzoitika kana kuyerera kwemvura kunongoerekana kwamira, senge kana vharuvhu ichivharwa nekukurumidza kana pombi inongoerekana yavharwa. Izvi zvinoita kuti simba rekinetic rishandurwe kuita mhepo yekumanikidza inopararira pamwe nepombi. Uku kuvhunduka kunogona kukonzera kuputika kwepombi, kusunungura flange, kana kukuvara kwevharuvhu. Butterfly mavharuvhu uye butterfly cheki mavharuvhu anosiyana mukugona kwavo kubata sando yemvura nekuda kwekugadzira kwavo uye nzira dzekushanda.
6.1 Butterfly mavharuvhu nesando yemvura
Mamhanyiro evhavhavhavhavhavha inovhara zvinoenderana nemashandiro ayo (manual, pneumatic, kana electric). Kuvhara nekukurumidza kunogona kukonzera nyundo yemvura, kunyanya mumasisitimu ane kuyerera kwakanyanya kana kudzvinyirira kwakanyanya. Izvi zvinoda kunyatsotariswa mumapombi masisitimu.
Butterfly mavharuvhu haana kugadzirwa kudzivirira kudzokera shure. Kana paine njodzi yekudzokera kumashure muhurongwa, nyundo yemvura inogona kuwedzeredzwa nekudzokera kumashure.
6.2 Butterfly Tarisa mavharuvhu nesando yemvura
Butterfly cheki mavharuvhu (double-disc cheki mavharuvhu) otomatiki kuvhara uchishandisa chitubu-akatakura kaviri discs kudzivirira backflow. Izvo zvakagadzirirwa kuti zvipindure nekukurumidza kune shanduko mukuyerera kwekutungamira uye kuve nechokwadi chekuvhara ipapo ipapo kana mvura yamira kana kudzosera kumashure, ichidzivirira sisitimu kubva mukukuvadzwa kwekudzoka. Zvisinei, kuvharika uku nokukurumidza kunogona kukonzera sando yemvura.
