Abstract: PROBLEM TO BE SOLVED: To provide a butterfly valve 1 provided with good sealability as compared with a conventional one.
SOLUTION: A bearing 4 is press-fitted in a through hole 2B in a radial direction of a housing 2 and a seal means 6 is energized toward the bearing 4 by a coil spring 7. A seal means 6 consists of a plate 16 on which the coil spring 7 is abutted and three annular seal member 15 inside thereof. The annular seal member 15 is strongly gripped between the plate 16 and the bearing by elastic force of the coil spring 7.

Abstract: PROBLEM TO BE SOLVED: To prevent easily the water leakage from a packing member at a bearing section with the valve spindle in a valve casing without cutting off the water in the pipeline.
SOLUTION: A preventive device of water leakage of a gate valve etc., is equipped with a valve body and a valve spindle 6, and the leakage of water from the valve spindle 6 is prevented by a packing member 8 and a packing gland 9 that are provided so as to surround the valve spindle 6 at the bearing area of the valve spindle 6. When the water is leaked from the packing member 8, this preventive device of water leakage has moreover the first annular seal member 12 that one end face is contacted closely to the position surrounding the outside of the packing member 8, and an inner circumference face is contacted closely to the packing gland 9 between the valve casing 2 and a packing gland 9; the fixing member 17 that is fixed to the packing gland 9 and faces in a specified distance to the outer circumference face of the valve spindle 6, in the side of valve spindle 6 extended to the outside operation means from the packing gland 9; and the second annular seal member 13 that is installed tightly in the close contact condition, so that an inner circumference face is closely contacted to the outer circumference of the valve spindle 6 against the fixing member 17.

Abstract: PROBLEM TO BE SOLVED: To provide a dispensing head with which a service life of a consumable body packing or the like can be lengthened while high sealability is kept. SOLUTION: The dispensing head 20 includes a body 36 to be attached to a spear valve SV, a plunger 31 which is incorporated into the body 36 so that it can rise/lower, a beverage passage D formed in the plunger 31, and a gas passage G formed between the interior of the body 36 and the exterior of the plunger 31. The body packing 37 which seals a gas passing through the gas passage G is provided between the exterior of the plunger 31 and the interior of the body 36 so that it can rise/lower with respect to the body 36. The plunger 31 is lowered whereby the body packing 37 interposed between the plunger 31 and the spear valve SV comes into tight contact with the spear valve SV.

Abstract: PROBLEM TO BE SOLVED: To provide a gas treating device operated in treating cycle. SOLUTION: A part of cycle is especially a PSA, a TSA or a VSA device provided with one or plural gas treating vessels having an adsorbent, and treatment is attained at lower pressure than atmospheric pressure. Respective vessels are provided with at least one orifice, at least one gas pipe communicated to the orifice and at least one valve arranged at the gas pipe and controlling the gas flow of the gas flowing through the pipe. The valve is provided with a means for operating the valve and a sealing means. The means for maintaining a protective gas atmosphere is arranged around the sealing means and the means for operating the valve, the penetration of a soil harmful to the adsorbent into the treating vessel is prevented, and especially the penetration of the moisture liable to inactivate molecular sieves, that is the adsorbent, so that the protective gas atmosphere may be formed and maintained around these.
