Mamiriro ekunze muChina ashanduka kutonhorera, asi mabasa ekugadzira eJinbin Valve Factory achiri kuramba aine shungu. Munguva pfupi yapfuura, fekitori yedu yapedza batch yemirairo ye ductile iron yakapfavachisimbiso mavharuvhu gedhi, izvo zvaiswa pasuru uye kutumirwa kunzvimbo yaienda.

Iyo inoshanda nheyo ye ductile iron soft sealwedge gedhi vharafuinobva pakugadzirwa kwayo kwakakosha uye zvinhu zvinoshandiswa. Chinhu chikuru chevhavha iyi igedhi, iro rakaputirwa murubha rakakosha rose. Panguva yekushanda, hunde yevharuvhu inotenderedzwa kufambisa gedhi kumusoro nekudzika, nekudaro kucheka kana kubatanidza mvura mupombi. Nzvimbo mbiri dzekuvharisa dzegedhi dzinowanzoita chimiro che wedge, uye saizi yekona ye wedge inosiyana zvichienderana neiyo parameter yevhavha. Kana gedhi rakavharwa, zvinhu zverubha zvinonamatira zvakasimba kuchigaro chevharuvhu nekuda kwekushanduka kwe elastic, kuwana chisimbiso uye zero kuvuza.

Iko kushandiswa kweiyo ductile iron zvinhu kunopa yakanaka mechanical zvivakwa uye corrosion resistance, nepo tekinoroji yekuisa chisimbiso yakapfava inovimbisa kuita chisimbiso uye hupenyu hurefu hwebasa revhavha. Mukuwedzera, pasi pemuviri wevhavha ye ductile iron soft sealmavharuvhu egedhi remvurainowanzogadzirwa nepasi rakati sandara kudzivirira kuunganidzwa kwemarara, kuderedza kutadza kwekuvhura nekuvhara, uye kuve nechokwadi chekuyerera kwemvura yakatsetseka. Iyo tsinde yevharuvhu inowanzo gadzirwa ine matatu O-mhete zvisimbiso kuderedza frictional resistance panguva yekuchinja, kuve nechokwadi chekushanda kuri nyore uye hapana kubuda kwemvura.

Mamiriro ekushandisa e ductile iron soft sealresilient gedhi mavharuvhumuhupenyu hwezuva nezuva zvinosanganisira asi hazvigumiri kune zvinotevera zvinhu:

1. Mvura yemvura: Mavharuvhu akavharidzirwa akavharidzirwa anogona kushandiswa munzvimbo dzekugara uye dzekutengesa chivako chemvura yekufambisa mapaipi kudzora kukanganisa uye kubatana kwekuyerera kwemvura, kuve nechokwadi chekuchengetedza uye kuvimbika kweiyo nzira yekupa mvura.

2. Kugadziriswa kwetsvina: Mumaguta ekugadzirisa tsvina yemvura uye masisitimu emvura, mavharuvhu akavharwa akapfava anoshandiswa kudzora nekudzora kuyerera kwetsvina, kudzivirira kubuda kwetsvina, uye kuchengetedza utsanana kwezvakatipoteredza.

3. Kuvaka: Mukuvaka, mavharuvhu akavharwa akapfava egedhi anogona kushandiswa kubatanidza nekubvisa mapaipi enguva pfupi, kufambisa kuyerera kwemvura panguva yekuvaka.

4. Moto kudzivirira sisitimu: Muotomatiki sprinkler yekudzimisa moto system, yakapfava yakavharwa mavharuvhu egedhi anoshandiswa kuvharira uye kutonga chimiro papombi huru kuti ive nechokwadi chekupihwa kwemvura yemoto panguva.

5. Kudiridza kwekurima: Muminda yekudiridza masisitimu, mavharuvhu akavharwa akapfava anogona kushandiswa kudzora kuyerera kwemvura uye nekuwedzera kugona kwekushandisa kwemvura.

6. Zvishandiso zveindasitiri: Mune mamwe maitiro eindasitiri, sekugadzira chikafu, kugadzirwa kwemishonga, nezvimwewo, mavharuvhu akapfava emagedhi anoshandiswa kunyatso kudzora kuyerera kwemvura, kuve nechokwadi chemhando yechigadzirwa uye kuchengetedzwa kwekugadzirwa.

Ductile simbi yakapfava yakavharwa flange gedhi vharafu inogona kuve nechokwadi chekushanda kwakajairwa kwepombi masisitimu uye kuvandudza kuchengetedzeka kweinjiniya, ichivaita iyo yakasarudzika yevharuvhu yemhando mumasisitimu ekudzora mvura. Kana uine chero chaunoda, ndapota taura nesu pazasi uye uchagamuchira mhinduro mukati meawa makumi maviri nemana.
