摘要： Provision of an abnormality detection and suppression system for a valve apparatus, which is capable of detecting abnormal states such as leakage through valve seats or a gland/packing assembly and coping with the abnormality while ensuring protection for the valve apparatus by controlling a driving unit for a valve stem on the basis of information as detected, by means of a vibration sensor, a temperature sensor and a strain sensor are disposed internally of a valve stem 4 at a portion thereof which lies outside of a valve casing of the valve apparatus. When vibration of the valve stem brought abut by leakage through valve seats is detected by the vibration sensor in a fully closed state of the valve apparatus, a valve body thereof is driven further in the valve closing direction by a driving unit 13 controlled by a control unit, both being disposed externally of the valve casing, until the leakage and thus the vibrations disappear while monitoring simultaneously a load applied to the stem by the strain sensor. On the other hand, when a temperature change of the stem is detected by the temperature sensor in the fully open state of the valve apparatus, the control unit decides that the temperature change is due to leakage through a gland/packing assembly 12 of the valve apparatus to thereby control the driving unit so that the stem is driven to move the valve body in the valve opening direction while monitoring simultaneously a load applied to the stem until the change in the temperature is canceled out.

摘要： The known traveling steel pipe cutting machine of a milling type, which cuts a pipe while traveling in synchronism with a pipe manufacturing speed, is improved so as to facilitate the calculation of positional loci and the control of a milling cutter, to increase a rigidity of the machine and a life of the cutter, and to also make it possible to cut even a pipe having an asymmetric cross-sectional shape under the same set of operating conditions. A plurality of cutter heads each include a milling cutter, and are each supported and linearly fed in biaxial directions by respective guides and feed drive motors. A clamping device is positioned in the proximity of the milling cutters for holding and fixing the pipe. The cutter heads and the clamping device are disposed on a traveling truck. The machine is also provided with a control device for rotationally controlling the feed drive motors for moving the cutter heads on the basis of input data representative of cutting conditions such as a shape and dimensions of the pipe.
