Mavharuvhu ebhora ari pakati peanonyanya kushandiswa mavharuvhu mumaindasitiri nedzimba masisitimu ekuvimbika kwawo, kusimba, uye nyore kushanda. Ichi chinyorwa chinoongorora kuti chii chinonzi bhora vharafu, zvikamu zvaro zvakakosha (muviri, bhora, chigaro), kupatsanura, kudzvanywa uye saizi zviyero, uye actuation nzira. Kunyangwe iwe uri injinjini, nyanzvi yekutenga zvinhu, kana DIY anofarira, gwara iri richakubatsira kuti unzwisise nzira yekusarudza vharafu yebhora yakakodzera pane zvaunoda.
Chii chinonzi Ball Valve
A bhora vharafuivharuvhu yekota inoshandisa buri, bhora rakapwanyika, uye rinotenderera kudzora kuyerera kwemvura. Kana chibore chebhora chaenderana nepombi, mvura inoyerera yakasununguka; kutenderedza bhora 90 madhigirii kunovharira kuyerera zvachose. Dhizaini yaro yakapusa inovimbisa kukurumidza kushanda, kushoma kudonha, uye kuenderana nemvura, oiri, gasi, uye corrosive media.
Zvikamu Zvikuru zveBhora Varuvha
1. Bhora Valve Muviri
Thebhora vharafu muvirindiro goko rekunze rinogara zvinhu zvemukati. Inowanzo gadzirwa nezvinhu zvakasimba sesimbi isina tsvina, ndarira, kana PVC, zvichienderana nekushandiswa. Dhizaini yemuviri inotaridza kudzvanywa kwevhavha uye mhando yekubatanidza (yakarukwa, yakapepetwa, kana wafer).
2. Bhora Valve Bhora
Thebhora vharafu bhoraibhora rinotenderera rine bore (gomba) nepakati paro. Iyo inowanzo chrome-yakaputirwa kana yakaputirwa nezvinhu zvakaita sePTFE kuderedza kukweshera uye kuramba ngura. Iyo bhora chaiyo machining inovimbisa kuvharika kwakasimba uye kushanda kwakatsetseka.
3. Ball Valve Seat
Thebhora vharafu chigarochinhu chakaita serin'i chinoumba chisimbiso pakati pebhora nemuviri. Zvigaro zvinowanzogadzirwa nemidziyo yakapfava sePTFE kana yakasimbiswa thermoplastics kuti ive nechokwadi chekuvuza-kusaita basa, kunyangwe pasi pekumanikidzwa kwakanyanya.
Mhando dzeBhora mavharuvhu Kubva paKubatanidza Siira
1. Threaded Ball Valve
A threaded bhora vharafuine shinda dzechirume kana dzechikadzi kumagumo ayo, ichibvumira kuisirwa kwakananga-kuiswa mumapaipi. Ideal for low-pressure housing systems (semuenzaniso, pombi dzemvura, HVAC), mavharuvhu aya anodhura uye ari nyore kuisa pasina welding.
Applications:
- Mvura yekugara
- Gasi mitsetse
- Diki-mwero maindasitiri masisitimu
2. Flanged Ball Valve
A flanged bhora vharafuine mativi ane mativi akavharirwa kune mapaipi flanges. Aya mavharuvhu anobata yakakwirira-kumanikidza uye yakakura-dhayamita masisitimu, achipa nyore kugadzirisa uye disassembly. Gaskets pakati peflange inovimbisa yakachengeteka, inovuza-isina kubatana.
Applications:
- Oiri uye gasi mapaipi
- Chemical processing plant
- Mvura yekurapa zvivako
3. Wafer Ball Valve
A wafer bhora vharafu(kana kuti *clamp-style ball valve*) inoiswa sandwich pakati pemapipeline flanges uchishandisa mabhaudhi. Akabatana uye akareruka, mavharuvhu aya anoenderana nenzvimbo-inomanikidzirwa masisitimu asi anoshaya magumo ekubatanidza, achitsamira pakumanikidzwa kweflange yekuisa chisimbiso.
Applications:
- Chikafu uye chinwiwa kugadzirisa
- Compact HVAC masisitimu
- Low-pressure hydraulic systems
Ball Valve Zvikamu neKugadzira
1. Inoyangarara Bharavhavha
Bhora rinobatwa panzvimbo nezvigaro zviviri uye rinoyangarara zvishoma pasi pekumanikidzwa. Inokodzera mavharuvhu madiki kusvika epakati-kati, dhizaini iyi inodhura-inoshanda asi inogona kunetsekana nekukwira-kumanikidza kwepamusoro.
2. Trunnion Ball Valve
Bhora rinosungirirwa ne trunnion (pivot) mashandiro, kuderedza kushanda torque uye kubata yakakwirira kumanikidza. Inowanikwa mumafuta uye gasi mapaipi.
3. Yakazara Port vs. Yakaderedzwa Port
- Yakazara Port Ball Valve: Bore rinoenderana nedhayamita yepombi, kuderedza kuyerera kwekuyerera.
- Yakaderedzwa Port Ball Valve: Bore idiki, inoderedza saizi yevharuvhu uye mutengo asi kuwedzera kudonha kwekumanikidza.
Ball Valve Pressure Ratings uye saizi
Pressure Ratings
Mavharuvhu ebhora akayerwa zvichibva pakumanikidzwa kwawo kwakanyanya kubvumidzwa (semuenzaniso, ANSI Kirasi 150, 300, 600). Makirasi epamusoro anoratidza kudzvinyirira kukuru. Semuyenzaniso:
- Kirasi 150: 285 PSI pa100°F
- Kirasi 600: 1,440 PSI pa100°F
Zvinhu Zvinokonzera Kudzvinyirira Kugona:
- Simba rezvinhu
- Chigaro uye chisimbiso kuvimbika
-Kubatanidza mhando (flanged mavharuvhu anobata akakwira kudzvinyirirwa)
Size Standards
Saizi yevharuvhu yebhora inotangira pa¼ inch (yekushandiswa kwekugara) kusvika pamusoro pe48 inches (mapaipi emaindasitiri). Zviyero zvakajairika zvinosanganisira:
- NPT (National Pipe Thread): For threaded mavharuvhu.
- ASME B16.10: Yezviyero zvakatarisana.
- ASME B16.5: For flanged mavharuvhu.
Ball Valve Actuation Nzira
1. Manual Actuation
Inoshanda kuburikidza nelever kana handwheel. Zvakanakisa kune mavharuvhu madiki kana masisitimu anoda kusawanzogadziriswa.
2. Pneumatic Actuation
Inoshandisa mhepo yakamanikidzwa kuita otomatiki kushanda kwevharuvhu. Yakanakira nzvimbo dziri kure kana dzine njodzi.
3. Electric Actuation
Inofambiswa nemagetsi emagetsi, ichigonesa kubatanidzwa nekutonga masisitimu eiyo chaiyo yekuyerera manejimendi.
Maitiro Ekusarudza Iyo Yakakodzera Bhora Valve
1. Media Compatibility: Ita shuwa zvinhu (muviri, bhora, chigaro) ramba ngura kubva mumvura.
2. Kumanikidza uye Tembiricha: Matanidza chiyero chevharuvhu kune zvinodiwa nehurongwa.
3. Connection Type: Sarudza yakarukwa, yakachinjika, kana wafer zvichienderana nekugadzirwa kwepombi.
4. Port Size: Sarudza mavharuvhu akazara echiteshi chepamusoro-kuyerera masisitimu.
5. Actuation: Otomatiki kana kugadzirisa kazhinji kana kudzora kure kuchidikanwa.
Mhedziso
Mavharuvhu ebhora anochinja-chinja, akasimba, uye akakosha pakudzora kuyerera kwemvura mumaindasitiri. Kunzwisisa zvikamu zvavo-bhora vharafu muviri, bhora,uyechigaro-pamwe nemhando dzakadaithreaded, flanged,uyewaferbhora mavharuvhu, inovimbisa optimal system performance. Nekufunga kumanikidza kuyerwa, saizi, uye maitiro ekuita, unogona kusarudza vharafu inosangana nezvido zvako zvekushanda. Gara uchidyidzana nemugadziri ane mukurumbira kuti uvimbise mhando uye kutevedzera zviyero zveindasitiri.
