1. Isakhiwo se-valve yesango
Isakhiwo somzimba we-valve yesango sinquma ukuxhumana phakathi kwe-valve yomzimba kanye nepayipi, umzimba we-valve kanye nebhonethi.Mayelana nezindlela zokukhiqiza, kukhona ukuphonsa, ukubumba, ukuthungatha, ukuthungatha i-casting kanye ne-tube sheet welding.
Ngokuvamile, ngokucatshangelwa kwezomnotho, amavalvu anobubanzi obuncane obulingana noma obungaphezu kuka-50mm ayaphonswa, futhi lawo anobubanzi obuncane obungaphansi kuka-50mm ayakhiwa.Kodwa-ke, ngokuthuthukiswa kobuchwepheshe besimanje bokubunjwa nokubunjwa, lo mkhawulo unqanyulwe kancane kancane.Ama-valve akhiwe athuthukile afinyelela kumadayimitha amakhulu, kuyilapho ama-valve asakazwa kancane kancane athuthukela kuma-diameter amancane.Noma yiluphi uhlobo lomzimba we-valve yesango lungafojwa noma lwakhiwe, kuye ngezidingo zomsebenzisi kanye nezindlela zokukhiqiza eziphethwe umenzi.
2. Indlela yokugeleza yomzimba we-valve yesango
Umzila wokugeleza womzimba we-valve wesango ungahlukaniswa ngezinhlobo ezimbili: uhlobo olugcwele lwe-bore kanye nohlobo oluncishisiwe lwe-bore.Ububanzi bomzila wokugeleza ngokuyisisekelo bufana nobubanzi obujwayelekile be-valve, okuwuhlobo lobubanzi obugcwele;ububanzi bomzila wokugeleza buncane kunobubanzi obujwayelekile be-valve, okubizwa ngokuthi uhlobo lobubanzi obuncishisiwe.Kunezinhlobo ezimbili zomumo oncishisiwe wobubanzi: ukuncishiswa kobubanzi obufanayo kanye nokwehliswa kobubanzi obufanayo bemali.Isiteshi sokugeleza esimise okwe-taper siwuhlobo lokwehliswa kobubanzi obungafanani.I-aperture yokuphela kwe-inlet yalolu hlobo lwe-valve ngokuyisisekelo ifana nobubanzi begama, bese kancane kancane iyancipha kuze kube yilapho isihlalo se-valve sincishiswa sibe sincane.
Ukusetshenziswa kwesiteshi sokugeleza sobubanzi obuncishisiwe (kungakhathaliseki ukuthi ukuncishiswa kwe-tapered-shaped-shaped non-uniform diameter noma ukunciphisa ububanzi obufanayo), inzuzo yayo ukuthi i-valve yokucaciswa okufanayo inganciphisa ubukhulu besango, ukuvulwa nokuvala. amandla kanye nomzuzu;ukungahambi kahle ukuthi ukumelana nokugeleza kuyanda kanye nokucindezela Ukunciphisa kanye nokusetshenziswa kwamandla kuyanda, ngakho-ke i-shrinkage cavity akufanele ibe nkulu kakhulu.Ukuze kuncishiswe i-tapered diameter yeshubhu, isilinganiso sobubanzi bangaphakathi besihlalo se-valve kuya kububanzi obujwayelekile buvame ukuba ngu-0.8~0.95.Kumavalvu anobubanzi obuncishisiwe anobubanzi obuncane obungaphansi kuka-250mm, ububanzi bangaphakathi besihlalo sevalvu ngokuvamile buphansi ngesinyathelo esisodwa kunobubanzi obungajwayelekile;kumavalvu anobubanzi obuncishisiwe anobubanzi obuncane obulingana noma obungaphezu kuka-300mm, ububanzi bangaphakathi besihlalo sevalvu ngokuvamile buphansi kunobubanzi obujwayelekile ngezinyathelo ezimbili.
I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
