Munguva pfupi yapfuura, ndakavhiringika neshinda dzakasiyana zvinodiwa mumifananidzo yevatengi vakasiyana.Kuti ndione misiyano, ndakawana ruzivo rwakakodzera uye ndakapfupisa senge pazasi:
Pipe tambo: inonyanya kushandiswa pakubatanidza pombi, iyo yemukati nekunze shinda inogona kusimba, ine yakatwasuka chubhu uye cone chubhu maviri akatsanangurwa.
Yakajairika pombi tambo inonyanya kusanganisira zvinotevera: NPT, PT, G zvichingodaro.
1.NPT thread: American standard 60 degree tapered pipe thread
NPT: zita rakazara iNational Pipe Thread, YeyeUS standard 60 degree tapered pombi shinda, inoshandiswa muNorth America, kuwana GB / T12716-1991.
2.PT(BSPT) thread: European and Commonwealth 55 degree yakavharwa koni thread
PT(BSPT): zita rakazara ndiBritish Standard Pipe Thread, ndeye 55 madhigirii akavharidzirwa koni shinda, ndeyemhuri yeWyeth tambo, inoshandiswa muEurope neCommonwealth nyika, inowanzoshandiswa muindasitiri yemvura uye gasi pombi, taper 1:16, yekuwana GB. / T7306-2000.
G shinda: 55 dhigirii isina-shinda yekuisa chisimbiso pombi shinda
G ndeye 55 dhigirii isina-shinda yakasungwa sealing chubhu shinda, imhuri yeWyeth.Yakanyorwa saG, zvinoreva shinda yecylindrical.GB / T7307-2001.
Musiyano uripo pakati pemetric threads neinch threads:
Tambo dzemetric dzinomiririrwa nepitch, nepo US-inch shinda dzinomiririrwa nenhamba yeshinda pa inch;
Metric shinda iri equilateral 60 madhigirii zino mhando, padiki shinda iri isosceles 55 madhigirii mazino mhando, American shinda nokuda chiuno 60 madhigirii zino mhando.
Tambo dzemetric mumayuniti emetric (eg mm), shinda dzakagadzirwa neAmerica neBritish mumainch unit (eg inch)
Kana paine rumwe ruzivo rwandisina kutaura, kana paine chikanganiso, ndizivisei.
Isu tiri makore gumi nemashanu zviitiko zveCNC machining zvikamu mugadziri, padyo neShanghai.Kana iwe uine RFQ inoda rutsigiro, BATA nesu kuti tiwane mahara quote.
