    摘要： A coating that is configured for use on parts of a control valve. The configurations may incorporate various material layers, preferably that form a layered structure on a base or substrate (for example, an Inconel body). In one implementation, the layered structure can be arranged as “stacked” individual layers that exhibit different concentrations or ratios of materials, including by example tungsten carbide and nickel alloy. The concentration of tungsten carbide may increase from an innermost layer to an outer most layer. This feature can extend service life of the parts, particularly when in use with highly-erosive process fluids, like particle-entrained fluids commonly found in hydrocracking or refining operations. Manufacture of the layered structure on the parts may require use of additive manufacturing technology in order to deposit layers of material of varying composition and thickness on the unique fluted design contemplated herein.

    摘要： Provide is a relief valve in which the flexibility of an attaching position is higher than a conventional relief valve. In the relief valve of the present invention, a discharge hole for discharging a fluid is arranged on a side surface of a cylindrical portion which protrudes from an end surface of a head portion in a bolt-type valve body. A direction change member which changes a direction in which the discharge hole is open to an arbitrary direction is provided. In this way, the relief valve is attached to a fluid device, and then with the direction change member, it is possible to direct the fluid discharge direction to a desired direction, and accordingly, the flexibility of the attaching position of the relief valve is enhanced as compared with the conventional relief valve.

    摘要： A shut-off member of a pressure reducing valve of a pressure regulator device, such as a diaphragm-type first stage for scuba diving, includes an enlarged head connected to a shaft and cooperating with a valve seat that separates a chamber supplied with high pressure gas from a chamber in which gas is at a lower pressure. The enlarged head and an end section of predetermined length of the shaft, connected to the enlarged head, are seamlessly coated with at least one layer of elastomeric material. Such coating of elastomeric material is limited to an end portion of the shaft connected to the enlarged head and the coated shaft portion is entirely contained in the high-pressure chamber in any operating position of the shut-off member.

    摘要： This valve is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid. The valve includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal, a hollow body inside which the blocking member is mobile and which defines at least one bore for receiving the journal, and a bearing disposed around each journal and inside the bore of the body enabling support of the journal and guidance thereof in rotation relative to the bore, thereby centering the journal. The valve further includes a device for immobilizing and sealing for maintenance the journal relative to the body of the valve. This immobilization device is disposed on the same side of the bearing as the internal volume of the hollow body and is maneuverable via the bearing to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal in the bore and vice versa.

    摘要： Cooking appliance having an external control panel equipped with one or more regulating valves, where the rotary regulator organ is equipped with various peripheral openings for supplying a flow Q. For the supply of one or another type of gas, NG or LPG, either the control knob or a bezel disk in the external panel are interchangeable on the appliance, being chosen between two different available units, one and the other permitting two different angular position limits A2, A3 of the regulator organ or the supply of a constant flow Qmin through one or another opening with calibrated sections, respectively for NG or LP gas. An appendix in the control knob guided in a slide groove on the control panel of the appliance, or a tongue on the bezel disk stopping the rotation of the control knob, determines the travel limit A2 for the supply of Qmin of NG.

    摘要： A conical rotary valve for chromatographic applications is provided, including a valve stator, a valve rotor, a drive adaptor and a pair of stoppers each mounted to the stator. The drive adaptor is rotatable and coupled to the valve rotor for transmitting a rotating force thereto. The drive adaptor has a body and a pair of radial arms projecting from the body radially outward from the axis of rotation on opposite sides thereof. Each of the pair of radial arms is movable along a respective arcuate travelling course with respect to the stator. The stoppers are each positioned to obstruct one of the radial arms at an end of the corresponding travelling course. The stoppers are positioned to simultaneously engage the radial arms, thereby balancing the reaction forces created within the valve when the radial arms reach the ends of their travelling courses.
