Chitsauko 1 - Chii chinonzi vharafu yebhora?
A PVC kana polyvinyl chloride bhora vharafu ipurasitiki pa-off valve ine bhora rinotenderera rine buri rinomisa kuyerera kwemvura nekutenderedza bhora kota kutendeuka. Iyo yakasimba zvakanyanya, inodhura-inoshanda uye inogona kushandiswa kudzora kuyerera kwemvura, mweya, makemikari anoparadza, asidhi uye mabhesi. PVC bhora mavharuvhu ane yakanakisa yakaderera tembiricha uye kumanikidza kuramba, asi yakaderera mechanicha simba. Semavharuvhu ese ebhora, mavharuvhu ePVC anomira kuyerera nekutenderedza bhora 90°.

Nheyo yePVC bhora vharafu ibhora rinotenderera, rinonzi bhora rinotenderera. Dzinde riri pamusoro pebhora ndiyo nzira inoshandura bhora, iyo inogona kuitwa nemaoko kana yega, zvichienderana nekugadzirwa kwevhavha. Ivhavha inovhura kana mubato wakaenzana nepombi uye inovhara kana mubato uri perpendicular kune pombi.

PVC mavharuvhu ebhora akagadzirwa nepurasitiki isingabatike uye anogona kumira tembiricha kubva -14°C kusvika -140°C. Ivo vanoshandira zvakawanda zvezvinangwa zvakafanana seyechinyakare bhora mavharuvhu, asi akareruka, compact, nyore kuisa, uye anokwanisa kuchinjika kune akasiyana siyana ekushandisa.

Chitsauko 2 - Mhando dzePVC Ball Valves
Mhando dzakasiyana dzePVC bhora mavharuvhu dzakagadzirirwa kusangana nemashandisirwo chaiwo. Iwo akakamurwa nehuwandu hwezviteshi, rudzi rwechigaro, gungano remuviri, ndima dzebhora uye saizi yebore. Chinhu chekusarudza pakusarudza rudzi rwevhavha yebhora ndiyo inoshandiswa, iyo inotarirwa nekumanikidzwa, ukuru, kutonhora, nhamba yezvikepe zvinodiwa, kupera kwekugadzirisa uye kugadzirisa.

PVC bhora mavharuvhu anogadzirwa kubva kuvinyl, iyo thermoplastic zvinhu inoshandura zvimiro zvemuviri kana ichipisa kana kutonhora. Kufanana nese thermoplastics, PVC ipurasitiki ine hushamwari hwezvakatipoteredza inogona kunyungudutswa uye kuumbwa patsva kakawanda. Pamusoro pekushandiswa mukugadzirwa kwePVC bhora mavharuvhu, PVC inoshandiswawo zvakanyanya mukugadzirwa kwepombi.

otomatiki vharafu
Otomatiki PVC bhora vharafu inogona kuva maviri-nzira kana matatu-nzira. Ivo vane pneumatic kana yemagetsi actuator inogona kudzorwa nemaoko neremote control kana kuve nechirimo michina. Self-actuated PVC bhora mavharuvhu akagadzirirwa kukonzeresa bhora pavharuvhu kuti rivhure kana kuvhara kuti risunungure kana kumisa kuyerera kwenhau uye rinogona kushandiswa kune dzakasiyana siyana media kubva kumvura kusvika gasi nemafuta.

Tarisa vharafu
PVC bhora cheki mavharuvhu anoshandiswa uko kuyerera kwemashure kunogona kukuvadza sisitimu kana kukonzera kusvibiswa kwefiltration uye kupomba system. Iwo otomatiki bhora vharafu inobvisa kudzvanywa muhurongwa. PVC cheki mavharuvhu matrunnions anovhara nekumanikidza kana kudzvanywa kwasvika pane imwe nhanho. Ivo vanoshandiswa mukugadzira makemikari, kurapwa kwemvura uye makemikari kutonhora maitiro. Kusiyana nemavharuvhu ePVC, cheki mavharuvhu haana dzinde kana mubato uye ari nyore mukuvaka.

Flanged PVC Ball Valve
Chinhu chakasarudzika cheiyo flanged PVC bhora vharafu ndiyo nzira yekubatanidza yayo, ndiko kuti, iyo flange. Vane kuyerera kwepamusoro nekuti ivo vanowanzozara yakazara. Flanged PVC bhora mavharuvhu anowanikwa aine maviri, matatu kana mana zviteshi, akareruka uye ari nyore kuisa. Ukobvu hweflange hunosiyana zvichienderana nekumanikidzwa kwakaiswa. PVC flanged bhora mavharuvhu anoshandisa adhesive glue kana mabhaudhi ane gaskets.

Inoyangarara PVC Bhora Vvhavha
Iine PVC bhora vharafu inoyangarara, bhora rinomiswa mumvura uye rinobatwa panzvimbo nechigaro chevharuvhu chakamanikidzwa. Iyo shaft yakasungirirwa kumusoro kwebhora, uye chikamu chechina chemubato chinopa nzvimbo yakatsetseka kubva pakavhurika kusvika pakavharwa. Bhora parinotendeuka, rinodzvanywa pachigaro charo, richimisa kuyerera. Bhora rinoyangarara mumutumbi wevharuvhu, nokudaro zita revhavha.

Yakazara Bore PVC Bhora Vvhavha
Kuti uwane mavharuvhu ebhora ePVC akazara, kuvhura mubhora kunofanana nedhayamita yepombi. Nemhaka yokuti gomba riri muvharuvhu rakaenzana nepombi, kana vheji yakazaruka, kuyerera kwepakati hakubvumirwi uye hapana kudonha kwekumanikidza kwemhando ipi zvayo. Mavharuvhu ebhora akazara ePVC anoonekwa semavharuvhu ekudzoreredza masisitimu anoda kudonha kwepasi uye kuyerera kwakanyanya coefficients.

Manually Operated Valve
Pakati pemhando dzakasiyana dzePVC bhora mavharuvhu, manyorero ekushandisa ndiyo yakapusa uye yakanyanya nyore kushandisa. Vhura nzira mbiri dzePVC bhora nekufambisa mubato wakafanana nepombi. Kuti uvhare valve, fambisa mubato perpendicular kune pombi. Kuvhura kana kuvhara valve kunoda chikamu chechina chemubato mune chero nzira.
