Kunyangwe kusarudzwa kwenzira yekubatanidza pakati pevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharuvhavhavhavhavhavhavha vhevhisi kana mbombo ya vhurereli i ṱanganedzani nga ha vhuya vhu ⁇ i tshi ṱuṱuwedza musidzana we vhezheni ye vharuu vha tshi shumisa,ho vhuya,ku vhuya nahone. Nzira dzekubatanidza vharuvhu dzakajairwa dzinosanganisira: kubatanidza flange, wafer connection, butt welding connection, threaded connection, ferrule connection, clamp connection, self-sealing connection uye mamwe mafomu ekubatanidza.
A. Flange kubatana
Flange yekubatanidza ndeyeflanged butterfly valveine maflange kumagumo ese emuviri wevharuvhu, ayo anowirirana nemaflange ari papombi, uye anoiswa mupombi nekusunga maflange. Flange yekubatanidza ndiyo inonyanya kushandiswa yekubatanidza fomu mumavharuvhu. Flanges yakakamurwa kuita convex surface (RF), flat surface (FF), convex uye concave surface (MF), nezvimwewo.
B. Wafer connection
Ivhavha inoiswa pakati pemaflange maviri, uye muviri wevhavha yewafer butterfly valvekazhinji ine buri rekumisa kuti ribatsire kugadzwa nekuisa.
C. Solder connection
(1) Butt welding connection: Migumo yese yemuviri wevharuvhu inogadziridzwa kuita butt welding grooves zvinoenderana nezvinodiwa butt welding, inoenderana newelding grooves yepombi, uye inonamirwa papombi newelding.
(2) Socket welding yekubatanidza: Migumo yese yevhavhavha inogadziriswa zvinoenderana nezvinodiwa zvesocket welding, uye yakabatana nepombi ne socket welding.
D. Kubatana kwe thread
Treaded connections inzira iri nyore yekubatanidza uye inowanzoshandiswa kune mavharuvhu madiki. Muviri wevharuvhu unogadziriswa zvichienderana neshinda yega yega, uye kune marudzi maviri eshinda yemukati uye yekunze. Inopindirana neshinda papombi. Kune mhando mbiri dzekubatanidza kune threaded:
(1) Kuisa chisimbiso chakananga: Idzo shinda dzemukati nekunze dzinotamba zvakananga basa rekuisa chisimbiso. Kuti ive nechokwadi chekuti chinongedzo hachibvire, chinowanzozadzwa nemafuta ekutungamirira, thread hemp uye PTFE raw material tepi; pakati peiyo PTFE mbishi tepi inoshandiswa zvakanyanya; chinyorwa ichi chine yakanaka corrosion resistance uye yakanakisa yekuisa chisimbiso. Zviri nyore kushandisa uye kuchengeta. Pakuparadzanisa, inogona kubviswa zvachose nokuti ifirimu isina kunamatira, iyo iri nani kudarika mafuta ekutungamirira uye thread hemp.
(2) Kuisa chisimbiso chisina kunanga: simba rekusimbisa shinda rinoendeswa kune gasket pakati pezvikepe zviviri, kuitira kuti gasket iite basa rekuvhara.
E. ferrule connection
Kubatana kweferrule kwakangogadzirwa munyika yangu mumakore achangopfuura. Kubatana kwayo uye chisimbiso musimboti ndewekuti kana nati yakasimbiswa, iyo ferrule inoiswa pasi pekumanikidzwa, zvekuti mupendero weiyo ferrule unoruma mumadziro ekunze epombi, uye iyo yekunze koni pamusoro peiyo ferrule yakabatana nejoini pasi. pressure. Mukati memuviri uri padhuze nepamusoro petapered, saka kuvuza kunogona kudzivirirwa zvakavimbika. Zvakadai semavharuvhu emidziyo. Zvakanakira iyi fomu yekubatanidza ndezvi:
(1) Saizi diki, huremu huremu, chimiro chakareruka, nyore disassembly uye kusangana;
(2) Simba rekubatanidza rakasimba, kushandiswa kwakasiyana-siyana, kupikisa kwepamusoro (1000 kg / cm 2), kupisa kwepamusoro (650 ° C) uye kuvhunduka uye kudengenyeka;
(3) Zvinhu zvakasiyana-siyana zvinogona kusarudzwa, zvakakodzera anti-corrosion;
(4) Zvinodiwa zvekugadzira machina hazvina kukwirira;
(5) Yakanakira kuiswa kwepamusoro-soro.
Parizvino, fomu rekubatanidza ferrule rakagamuchirwa mune zvimwe zvidiki-diameter valve zvigadzirwa munyika yangu.
F. Grooved connection
Iyi inzira yekubatanidza inokurumidza, inongoda mabhaudhi maviri, uyethe grooved end butterfly valveinokodzera kudzvinyirira kwakadererabutterfly valvesizvo zvinowanzo patsanurwa. zvakadai semavharuvhu ehutsanana.
G. Internal self-tightening connection
Mafomu ese ekubatanidza ari pamusoro anoshandisa simba rekunze kudzikamisa kudzvanywa kwepakati kuti uwane chisimbiso. Inotevera inotsanangura iyo yekuzvisimbisa yekubatanidza fomu uchishandisa yepakati pressure.
Ring yaro yekuisa chisimbiso inoiswa mukati makoni uye inoita imwe kona nedivi rakatarisa pakati. Kudzvinyirirwa kwepakati kunoendeswa kune yemukati cone uye ipapo kune chisimbiso mhete. Pamusoro pekoni yeimwe kona, maviri echikamu masimba anogadzirwa, imwe ine Iyo yepakati mutsara wevharuvhu muviri wakafanana nekunze, uye imwe inotsikirirwa kumadziro emukati emuviri wevhavha. Simba rekupedzisira ndiro simba rinozvisimbisa. Kuwanda kwesimba repakati, ndiko kukura kwesimba rekuzvisimbisa. Nokudaro, iyi fomu yekubatanidza inokodzera mavharuvhu makuru.
Inofananidzwa nekubatana kweflange, inochengetedza zvinhu zvakawanda uye simba revanhu, asi inodawo imwe preload, kuitira kuti inogona kushandiswa zvakavimbika kana kudzvinyirirwa kwevhavha kusina kukwirira. Mavharuvhu akagadzirwa uchishandisa musimboti wekuzvisimbisa-kusimbisa chisimbiso kazhinji mavharuvhu ekumanikidza.
Kune nzira dzakawanda dzekubatanidza valve, semuenzaniso, mamwe mavharuvhu madiki asingade kubviswa ane welded nemapombi; mamwe mavharuvhu asiri esimbi anobatanidzwa nezvigadziko uye zvichingodaro. Vashandisi vevharuvhu vanofanirwa kurapwa zvinoenderana nemamiriro chaiwo.
Cherechedza:
(1) Nzira dzose dzekubatanidza dzinofanira kureva zviyero zvinoenderana uye kujekesa zviyero zvekudzivirira valve yakasarudzwa kubva pakuiswa.
(2) Kazhinji, pombi hombe-dhayamita nevharuvhu zvakabatanidzwa neflange, uye diki-dhayamita pombi nevharuvhu zvakabatanidzwa neshinda.
