抄録

For the users of automatic control valves, leakage of the fluid from the gland packing portion has been a problem as main cause of failure. In this research, the measuring method of the radial pressure of the gland packing, which is directly related to the sealing characteristics, is proposed. The semiconductor pressure transducer is attached to the bonnet, and through the grease filled in the hole in the bonnet, the radial pressure was directly measured. First, the validity of the proposed method was confirmed by comparison of the result to the pressure value expected from the strain of the bonnet. Next, this measuring method was applied to the model system. The radial pressure distribution of the piled packing and its dynamic behavior under conditions the stem was driven was successfully observed. Consequently, the method was shown to be useful to observe the radial pressure distribution, especially in dynamic conditions.
