Product features of national standard swing check valve
1. Chigadzirwa chacho chine chimiro chinonzwisisika, chisimbiso chakavimbika, kushanda kwakanakisisa uye kutaridzika kwakanaka;
2. Nzvimbo yekuisa chisimbiso yakafukidzwa neCo based cemented carbide, iyo ine zvakanaka kupfeka kusagadzikana, kusaita ngura, kuramba kukwenya uye hupenyu hurefu hwebasa;
3. Yakavakwa mupini shaft chimiro inoderedza kubuda kwekunze uye yakavimbika mukushandiswa;
4. Kana dzvinyiriro yakakura kudarika kana yakaenzana ne 16.0mpa, iyo self tightening chisimbiso chimiro inogamuchirwa mukamuri yepakati yevhavha. Iyo yakakwirira iyo yepakati kudzvanywa iri, zviri nani kuita chisimbiso kuita;
5. Zvinhu uye saizi yeflange uye butt welding end inogona kusarudzwa zvine musoro zvinoenderana nemamiriro chaiwo ekushanda kana zvinodiwa nemushandisi kuti asangane nemhando dzakasiyana dzeinjiniya zvinodiwa.
