摘要： PROBLEM TO BE SOLVED: To provide a ball valve capable of certainly relieving a fluid pressure abnormally raised in a cavity, retaining the pressure in the cavity to a normal value and being not restricted in a pressure loading direction with respect to a ball valve element.
SOLUTION: In the ball valve, the ball valve element 6 having a penetration hole 5 is stored in the cavity 4 provided with a pair of seal rings 3, 3 formed on a flow passage 2 in the valve body 1 and opposed in an axial direction. A relief hole 7 for connecting the flow passage 2 with the penetration hole 5 is provided on the ball valve element 6 in the valve-closed state of the flow passage 2, and a relief valve 10 is provided on the relief hole 7. When the fluid pressure P in the cavity 4 is higher than a set pressure P
0 of the relief valve, the relief valve 10 is opened to relieve the fluid pressure P in the cavity 4 by releasing the fluid to the flow passage 2.

摘要： PROBLEM TO BE SOLVED: To prevent condensation from occurring in a valve actuator.
SOLUTION: A cylinder 4 incorporates a piston 5 linked to a valve 1 to be urged in a constant direction by a spring 16, and to be slid against the spring 16 in the reverse direction by compressed air conveyed from a compressed-air inlet 6a. When a solenoid valve 11 allows compressed air inlets 4a, 6a in the cylinder 4 to communicate with a compressed air source 18, a return pipe 22 connected to a discharge ports 4b, 6b in the cylinder 4 is shut off. When the solenoid valve 11 allows communication between the compressed air inlets 4a, 6a in the cylinder 4 and the compressed air source 18 to shut off, the return pipe 22 to communicate with the compressed air inlet 4a, 6a.

摘要： PROBLEM TO BE SOLVED: To provide an emergency cutoff valve capable of stopping a valve element at an opening between a fully opened state and a fully closed state in an opening at a degree not causing troubles in the operation of equipment, and preventing a situation where, due to an unintentional human erroneous operation during inspection, a valve becomes fully closed and a pipeline is stopped. SOLUTION: In this emergency cutoff valve, by engaging/disengaging a stopper member 27 with an engagement groove 25 provided in a rotator 24 fixed to a valve shaft 7 for closing a valve main body 1, rotation of the valve shaft 7 is regulated, and the opening of the valve main body 1 is restricted so that the opening does not become less than a predetermined value. By operation of an operation confirming means 28 for confirming that the stopper member 27 moved to an engagement position, an inspection operation of a valve drive means is allowed. An interlock means 43 is provided for disabling an inspection operation of the valve drive means at the time of non-operation of the operation confirming means 28. COPYRIGHT: (C)2007,JPO&INPIT
