Kune mhando dzakawanda dzedhisiki revharuvhu reshavishavizvichienderana nekushandiswa kwemavharuvhu emabhuruvhu, saizi dzakajairika dzevharuvhu yemabhuruvhu dzinobva kuDN50-DN600, saka tichaisa madhisiki emavharuvhu zvichienderana nehukuru hunoshandiswa nguva dzose.
1.Dhisiki yeValve yeNylon Coated
Kupfapfaidza nenylon inzira yakajairika yekuputira pamusoro iyo inopfapfaidza zvidimbu zvenylon muchimiro chemvura pamusoro pe substrate uye inoumba firimu renylon rakasimba uye rinogara kwenguva refu mushure mekusimba. Kupfapfaidza nenylon kune mashandisirwo akawanda uye mamiriro ekushandisa, heano mamwe emashandisirwo akajairika:
- Dziviriro inodzivirira ngura: Kuvhara kwenaironi kunogona kushandiswa sekudzivirira pamusoro pesimbi. Naironi ine zvinhu zviri nani zvinodzivirira ngura, inogona kuparadzanisa simbi nekunze kwemvura, zvichiita kuti vharuvhu irambe ichirarama kwenguva refu.
- Deredza kukweshana: Nylon ine hunhu huri nani hwekuderedza kukweshana, inogona kuderedza nyore nyore kukweshana pakati pechigaro chevharuvhu nedhisiki.
- Inodzivirira kupfeka: Nylon ine simba rakanaka rekudzivirira kupera, inogona kuderedza kukwenya kwepamusoro pediski.
2.PTFE Lining Valve Disc
- Hainamati: Pamusoro pedhisiki rePTFE panenge pakatsetseka uye hapanamati, zvinogona kuderedza zvinonamira kubva pazvipingamupinyi zviri pakati nepakati.
- Kuramba ngura: PTFE ine simba rakanaka rekudzivirira ngura, inonzi Mambo wepurasitiki nekuda kwehunhu hwayo hunoshamisa hwekudzivirira ngura, inogona kutsungirira akawanda masimbi ane acid uye alkali.
- Kusashanda kwemakemikari: PTFE ikusashanda kwemakemikari akawanda. Inogona kuramba ngura yemakemikari mazhinji.
- Haipfeki: Kunyangwe PTFE iri chinhu chakapfava, asi ine simba rakanaka rinodzivirira kupera kana tichienzanisa nedzimwe simbi dzakafanana nepurasitiki. Dhisiki ine PTFE pamusoro inogara kwenguva refu nekuda kwehunhu hwayo.
3.Dhisiki yeAruminiyamu yeBronze Valve
Aruminiyamu bronze imhando yemhangura inowanzo kuve nearuminiyamu, mhangura nezvimwe zvinhu zvakaita semanganese, iron uye zinc. Ine mabhenefiti akawanda anoita kuti ishandiswe zvakanyanya mumabasa akasiyana-siyana.
- Kudzivirira ngura zvakanaka: Aruminiyamu bronze ine simba guru rekudzivirira ngura, kunyanya mumvura yegungwa nemumvura ine munyu. Izvi zvinoita kuti ive chinhu chinoshandiswa zvakanyanya mumabasa ekugadzira ngarava dzegungwa nedzekunze kwenyika dzakadai semapropeller engarava, mavharuvhu nemapombi.
4.Nickel Plate Butterfly Valve Disc
- Hunhu hwekudzivirira ngura: Nickel plate inogona kudzivirira pamusoro pe ductile iron disc kubva mukuora kubva pakushanda.
- Kuomarara: Ne nickel plate, pamusoro pe DI disc unogona kuomarara kupfuura kare. Inogona kubatsira kuramba diski kubva pakushanda kwepakati.
5. Dhisiki yeRubber Lining Valve
- Kushanda zvakanaka kwekuvhara: Dhisiki ine rabha ichaita zvakanaka kwazvo pakuvharisa kana tichienzanisa nedhisiki resimbi, uye ichapa zvinhu zvinovimbika zvekuvhara. Inobatsira vharuvhu kudzivirira kubuda kwemvura.
6.Dhisiki yeVharuvhuti Inoyerera Zvikuru
- Dhizaini yakakosha yedhisiki inoyerera nekukurumidza inopa mashandiro akanaka ekuyerera. Zvichienderana neshavu yayo yakakosha uye saizi dzakarurama, inoderedza kuramba uye kuderera kwekumanikidzwa kwemidziyo inoshanda, uye inowana kuyerera kwakanyanya.
