Chitsauko 1 - Chii chinonzi vharuvhu yebhora?
Vharuvhu yebhora yePVC kana polyvinyl chloride ivharuvhu yepurasitiki inodzima ine bhora rinotenderera rine buri rinomisa kuyerera kwemvura nekutenderedza bhora kota yekutenderera. Inogara kwenguva refu, haidhuri zvakanyanya uye inogona kushandiswa kudzora kuyerera kwemvura, mhepo, makemikari anoparadza, acids uye mabhesi. Vharuvhu yebhora yePVC ine tembiricha yakaderera uye inodzivirira kumanikidzwa, asi ine simba shoma remakanika. Kufanana nemavharuvhu ese ebhora, mavharuvhu ebhora ePVC anomisa kuyerera nekutenderedza bhora 90°.

Pakati pevharuvhu yebhora rePVC ibhora rinotenderera, rinonzi bhora rinotenderera. Hunde iri pamusoro pebhora ndiyo nzira inotenderedza bhora, izvo zvinogona kuitwa nemaoko kana otomatiki, zvichienderana nekugadzirwa kwevharuvhu. Vharuvhu rinovhurika kana mubato wakaenzana nepombi uye rinovhara kana mubato wakatarisana nepombi.

Vharuvhu yebhora yePVC

Mavharuvhu ebhora ePVC akagadzirwa nepurasitiki isingatsvi uye anogona kutsungirira tembiricha kubva -14°C kusvika -140°C. Anoshanda zvakafanana nemavharuvhu ebhora echinyakare, asi akareruka, madiki, ari nyore kuisa, uye anokwanisa kuchinjika kune akasiyana mashandisirwo.

Chitsauko 2 - Mhando dzemavharuvhu ebhora ePVC
Mhando dzakasiyana dzemavharuvhu ebhora ePVC dzakagadzirirwa kusangana nezvinodiwa. Dzinorongwa nenhamba yemaports, rudzi rwechigaro, body assembly, nzira dzebhora uye saizi yebhore. Chinhu chinosarudza pakusarudza rudzi rwevharuvhu yebhora ndiko kushandiswa, uko kunotsanangurwa nekumanikidzwa, saizi, tembiricha, nhamba yemaports anodiwa, end fittings uye configuration.

Mavharuvhu ebhora ePVC anogadzirwa nevinyl, chinhu chinogadzirwa nethermoplastic chinochinja hunhu hwemuviri kana chapiswa kana kutonhodzwa. Kufanana nethermoplastics dzese, PVC ipurasitiki isingakuvadzi nharaunda inogona kunyungudutswa nekugadziriswazve kakawanda. Kuwedzera pakushandiswa mukugadzira mavharuvhu ebhora ePVC, PVC inoshandiswawo zvakanyanya mukugadzira mapaipi.

PVC bhora vharuvhu mhando
vharuvhu otomatiki
Vharuvhu yebhora yePVC inongoerekana yagadzirwa inogona kuva nemativi maviri kana matatu. Ine actuator yepneumatic kana yemagetsi inogona kudzorwa nemaoko ne remote control kana kuti ine spring mechanism. Mavharuvhu ebhora ePVC anozvishandira ega akagadzirwa kuti atange bhora riri pavharuvhu kuti rivhurike kana kuvhara kuti riburitse kana kumisa kufamba kwemagetsi uye anogona kushandiswa kune akasiyana-siyana emagetsi kubva mumvura kusvika kugasi nemafuta.

Vharuvhu yebhora yePVC inofambiswa nemhepo

Tarisa vharuvhu
Mavharuvhu ekuongorora bhora ePVC anoshandiswa apo kuyerera kwemvura kumashure kunogona kukanganisa sisitimu kana kukonzera kusvibiswa kwesisitimu yekusefa nekupomba. Ivharuvhu yebhora inongoerekana yaita otomatiki inoderedza kumanikidzwa musisitimu. Mavharuvhu ekuongorora ePVC ma trunnions anovhara nekumanikidzwa kana kumanikidzwa kwasvika padanho rakati. Anoshandiswa mukugadzirisa makemikari, kugadzirisa mvura uye kutonhora kwemakemikari. Kusiyana nemavharuvhu ePVC akajairika, mavharuvhu ekuongorora haana hunde kana mubato uye ari nyore kuvaka.

Flanged PVC Ball Valve
Chinhu chinoshamisa chevharuvhu yebhora yePVC ine flange inzira yayo yekubatanidza, kureva flange. Ine kuyerera kwakanyanya nekuti inowanzova yakazara. Mavharuvhu ebhora ePVC ane flange anowanikwa ane maports maviri, matatu kana mana, akareruka uye ari nyore kuisa. Ukobvu hweflange hunosiyana zvichienderana nekumanikidzwa kwainoshandiswa. Mavharuvhu ebhora ePVC ane flange anoshandisa glue inonamira kana mabhoti ane magaskets.

Inoyangarara PVC Ball Valve
Nevharuvhu yebhora yePVC inoyangarara, bhora rinorembera mumvura uye rinobatwa panzvimbo yaro nechigaro chevharuvhu chakamanikidzwa. Shaft inosungirirwa pamusoro pebhora, uye kota yekutenderera kwemubato inoita kuti pave nenzvimbo yakatsetseka kubva pakavhurika kusvika pakavharika. Bhora parinotenderera, rinodzvanywa pachigaro charo, zvichimisa kuyerera. Bhora rinoyangarara mumuviri wevharuvhu, ndosaka zita revharuvhu.

Yakazara Bore PVC Ball Valve
Kune mavharuvhu ebhora ePVC ane chiboore chakazara, gomba riri mubhora rinoenderana nedhayamita yepombi. Nekuti gomba riri muvharuvhu rakaenzana nepaipi, kana vharuvhu yakavhurika, kuyerera kwepakati hakudzoreki uye hapana kudonha kwekumanikidzwa kwerudzi rupi zvarwo. Mavharuvhu ebhora ePVC ane chiboore chakazara anoonekwa semavharuvhu ekudzoreredza masisitimu anoda kudonha kwekumanikidzwa kwakaderera uye ma coefficients ekuyerera kwepamusoro.

Valve Inoshandiswa Nemaoko
Pakati pemhando dzakasiyana dzemavharuvhu ebhora ePVC, kushanda nemaoko ndiko kuri nyore uye kuri nyore kushandisa. Vhura vharuvhu yebhora yePVC ine mativi maviri nekufambisa mubato wakaenzana nepaipi. Kuti uvhare vharuvhu, fambisa mubato wakatarisana nepaipi. Kuvhura kana kuvhara vharuvhu kunoda kutenderera kwemubato nehafu yemativi ese.
