Zusammenfassung:A valve. The utility model relates to motor component technology field in particular to motor valve technology field. The technical scheme for resolving the mentioned problems is as follows: the valve includes a bar and a valve at the end which are connected and provided a order-round at the joint. The bimetal valve is made from 5Cr21Mn9NI4N which is high temperature, erosion and collision resistant; the lower end of the bar is made of 4Cr9SI2 which provides high strength, high hardness and good plastic and surface hardness after heat treatment. The performance of the two materials can respectively adapt to the working environment so as to prolong durability of the valve.
