摘要： A mechanical shutdown valve for preventing an over pressure condition is described. A valve body has an inlet, an outlet, and a channel extending from the inlet to the outlet. A valve seat and a diaphragm are positioned in the valve body. The diaphragm controls a fluid flow through the valve body. A mesh is coupled to the diaphragm such that the mesh and the diaphragm separate an upstream portion of the channel from a downstream portion of the channel. The mesh extends from the diaphragm to an inner surface of the valve body and limits fluid flow between the diaphragm and the valve body. A spring biases the diaphragm towards the open position. A characteristic of the spring determines a differential pressure threshold between the upstream portion of the channel and a downstream portion of the channel at which the diaphragm engages the valve seat.

摘要： A flow control valve includes a valve body, a control member and a cover. The valve body has a receiving space, a resting face, a stepped face, a positioning groove and a plurality of water outlet holes. The control member is provided with an elastic portion, a sealing portion and an abutting face. When a flow pressure of the fluid is under a normal condition, the elastic portion of the control member is contracted inward, so that the abutting face of the control member is disposed at an open state. When the flow pressure of the fluid is under an abnormal condition, the elastic portion is expanded outward and abuts the stepped face of the valve body, so that the abutting face of the control member abuts the resting face of the valve body, to seal the water outlet holes of the valve body.

摘要： An insertable backflow preventer is presented. The backflow preventer is provided with a cylindrical housing. The housing has a flow transition zone, a proximal orifice/ball seat, a ball with a specific weight that equals or is close to the specific weight of the surrounding fluid, and a distal retaining screen. The housing can have a flange provided on the outside of the housing at one end to facilitate securing the valve in a pipe. The valve is self-cleaning, can be placed in any orientation in a pipe and has low hydraulic head-loss. The valve's unique cost-effective design provides for easy and relative quick installation, eliminates the need to reconfigure existing plumbing, and can be performance tested remotely. Properly installed, it can dramatically improve the security of, for example, potable water sources in a building or other context, and inasmuch as when installed it is not visible, it is tamper proof. The valve can be scaled to any size pipe or tube, and due to its internal flow dynamics is self cleaning. Multiple valves can be installed in series, and balls of varying specific weight can be used in each valve in such a series to allow for contexts where a range of fluids are sent through the same line, or to provide fail-safe operation in the event that contaminants change the specific gravity of the fluid.

摘要： Integrated flow control backflow preventer valve (“IFCBPV”) for new and existing wet- and dry-barrel fire hydrants, with barrel drain assemblies for dry-barrel hydrants, and hydrants equipped with such IFCBPVs, are presented. An exemplary IFCBPV can have a retaining screen comprising equidistant concave radial spokes intersecting at a central ring structure, a freely suspended check ball, and a lower ball seat with a seal. The upper surface of the retaining screen can be affixed to the hydrant's axial shaft, and can thus be used to open and close the hydrant via the ball. Alternatively, the retaining screen can be fixed and the axial shaft provided with a cup on its bottom that mates with the freely suspended ball that is caged between the retaining screen and the ball seat. An exemplary barrel drain assembly can comprise a spring-loaded piston, or alternatively, a check ball design as in the main barrel.

摘要： A forward check valve and a fuel cell system in which fluid control is performed with increased reliability when a highly active fluid is used are structured such that when an edge portion of a cap is joined to an edge portion of a valve housing, a peripheral edge portion of a diaphragm is pushed and sandwiched by a peripheral edge portion of the cap and a placement portion. Further, the diaphragm is formed of rubber. As a result, the peripheral edge portion of the diaphragm is compressed by the peripheral edge portion of the cap and the placement portion, so that the degree of contact at a contact portion between the placement portion and the peripheral edge portion of the diaphragm becomes very high. Consequently, in the forward check valve, joints of the members including a joint of the edge portion of the cap and the edge portion of the valve housing do not contact methanol.

摘要： A compressed-air control device includes at least one first component, and a second component arranged so as to be movable relative to the first component. A molded seal is arranged in a groove of the first component, and is in contact with the second component. A first chamber formed on one side of the molded seal between the first and the second components can be charged with a first pressure, and a second chamber formed on the opposite side of the molded seal between the first and the second components can be charged with a second pressure. The molded seal together with the first component forms at least one overflow valve.

摘要： A method for the production of a valve is provided comprising molding a valve body with a first mold, preloading the valve body with a second mold, molding a sealing portion in an open position onto the valve body, and releasing the preloaded valve body. The sealing portion enters a closed position when the preloaded valve body is released. When the valve is in use, the sealing portion opens when under a fluid pressure, and closes when the pressure is released.

摘要： An air release vent valve used to vent air from a liquid filled pipeline, the air release vent valve having a float valve deployed in a float valve housing extending from the pipeline and a surge suppressing shutter valve deployed in a vent passageway extending from said float valve housing such that said surge suppressing shutter valve is downstream from said float valve. The surge suppressing shutter valve includes an elastic shutter element that is pre-shaped to a normally open position and is configured to gradually deform to a closed position as a velocity of air flowing through said vent passageway increase so as to dampen the force of the closure of air release vent valve and prevent a pressure surge within the pipeline. Once a liquid level in the pipeline reaches the float valve, a float is raised so as to fully closes the vent passageway.

摘要： An expansion tank is disclosed in which a non-return valve is fitted in an outlet port of the expansion tank to limit backflow of coolant into the expansion tank in the event that the pressure in the expansion tank falls below the pressure in a return conduit thereby preventing the expansion tank from filling with coolant. The non-return valve and the expansion tank are formed as a single component and the non-return valve is located in an outlet port of the expansion tank.
