Standard nozzle kwarara mita
Amfani da misali nozzle a matsayin cutter sassa
Standard nozzle kuma aka sani da ISA1932 nozzle, tare da high zafin jiki da kuma matsin lamba juriya, tasiri juriya, tsawon aiki rayuwa, m kewayon, ma'auni daidaito da kuma high halaye, dace da wutar lantarki tashar high zafin jiki da kuma matsin lamba tururi, zafi cibiyar sadarwa bututu, high gudun kwarara kwarara ma'auni. Standard nozzle da aka tsara da kuma masana'antu bisa ga ƙasa misali GB / T2624-93, da kuma gwaji bisa ga ƙasa misali JJG640-94. Babu buƙatar daidaitawa na halitta.
