Abstract: A tapered rotary feed valve is manufactured or refurbished for use in feeding materials into a high temperature environment, so as to reduce the time and expense of break-in operation, by shaping the tapered bore of the valve body at ambient temperature to have greater clearance around the rotor in a sector of the valve body that is cooler when the valve is at stable operating temperature. As a result, when the valve first reaches operating temperature after being manufactured or refurbished the rotor and the bore of the valve body nearly fit and can quickly wear in to fit each other closely.
Abstract translation: 锥形旋转进给阀在制造或翻新中用于将材料输送到高温环境中，以便通过在阀门环境温度下成形阀体的锥孔以使其具有更大的间隙，从而减少打入操作的时间和费用 在阀体处于稳定的工作温度时，在阀体的一个扇区内的转子处于较冷的状态。 结果，当阀门在制造或翻新之后首先达到工作温度时，转子和阀体的孔几乎适合并且可以快速地磨损以便彼此紧密配合。
