摘要： A check valve construction is provided which includes a housing having a first flow path and a second flow path. Liquid flow is controlled within the first and second flow path by movable plungers having a sealing surface and a plurality of prongs that control the length of movement of the plunger within the housing. One of the plungers permits liquid flow while the other of the plungers prevents liquid flow in response to pressure change within the flow paths.

摘要： A mechanical leak arresting valve (204) is disclosed in which fluid through the valve is limited to a range between a predetermined minimum flow rate and a predetermined maximum flow rate, and where both a small or large downstream leak mechanically causes the valve to lock closed. The present invention uses a locking mechanism triggered by a pressure differential resulting from the downstream leak to block the flow of fluid through the valve (224) until the fluid source upstream is stopped. Reduction of the upstream pressure by the stopping of the fluid source automatically resets the valve without further manipulation.

摘要： A system including a discharge conduit (41) defining a flow passage for establishing fluid communication with liquid from a container. A resilient valve (80) is provided to extend across the discharge flow passage (52). The valve (80) defines a dispensing orifice (84) that opens when pressure on the valve interior side exceeds the pressure on the exterior side by a predetermined amount. A resilient baffle is located upstream of the valve (80). The baffle includes an occlusion member (142) supported by at least one resilient support member (144) which accommodates movement of the occlusion member (142) between a closed position occluding flow into at least a portion of the conduit flow passage when the baffle is subjected to an upstream hydraulic hammer pressure, and biases the occlusion member (142) to an open position permitting flow into the conduit flow passage adjacent the valve (80) when the baffle is not subjected to a hydraulic pressure.

摘要： An inflatable seating pad (10) consists of a hand operated pump (12) integrated within the top surface to inflate the pad with air. The pad (10) has a shut-off connector (6) at one corner which locates and is connected to a pressure relief valve (8). In use, the pad (10) is inflated by pushing upon the hand operated pump (12) to over inflate the pad. The shut-off connector (6) maintains the pressure in the pad (10). To set the pressure to a desired pressure the user actuates the pressure relief valve (pre-set to optimum pressure) to operate the shut-off connector (6) to allow air to exhaust through the pressure relief valve.

摘要： The invention relates to a thermal security device for cutting off gas pipelines, wherein gas transfer is prevented by said safety device when temperature increases in the section of the gas pipeline placed downstream from said security device, especially when connected gas apparatuses are in a closed position. The aim of the invention is to maintain production costs and dimensions at a level as low as possible. The inventive device comprises a check valve which prevents back flow from the gas pipeline which is placed downstream from said device. The inventive device also comprises a pressure sensitive element which is actuated by the pressure in the pipeline placed downstream from said safety device. Said pressure sensitive element is coupled to a cut-off valve in such a way that when pressure increases in the downstream pipeline said valve prevents gas from flowing into the pipeline. The inventive safety device is used to cut off automatically gas pipelines when temperature increases in an unacceptable way in the section of the pipeline which is placed downstream from said safety device.

摘要： By means of an activation pin for a valve connector, which activation pin is designed as a piston (301) with a piston rod (302), moving in the coupling house of the valve connector where the activation pin has a central drilling (303) and a piston valve (304) kept closed by a spring force, the aim is to produce a reliable activation pin which is reliable, cheap, has low aerodynamic drag and thus, is comfortable to use for pumping purposes and provides the shortest possible pumping time. Pursuant to the invention, this is achieved by the fact that one or more channels (303, 321) are defined by the piston rod (302) and/or the piston valve rod (322) in the assembled activation pin which channels (303, 321) are positioned in a mainly longitudinal direction in relation to the centerline (337) of the activation pin, of which the cross section approximately can be defined by at least one closed curve, which can be defined by two unique modular parametrisation Fourier Series expansions, one for each co-ordinate function (A), where (a), (b), 0 /= 0, p ELEMENT N, cp = cos-weighted average values of f(x); dp = sin-weighted average values of f(x); p = representing the order of trigonometrical fineness.

摘要： A multi-use flow control and pressure reducing valve includes an inlet chamber (A), an intermediate chamber (B), and an outlet chamber (C). A hydraulic gate member (3) forms the outlet chamber (C) and controls communication between the intermediate chamber (B) and outlet chamber (C) to control flow of fluid through the valve. The hydraulic gate (3) also establishes a control or actuating chamber (D) for receiving fluid therein to control the position of the hydraulic gate (3). The valve is separable in the axial direction into at least two parts (P1 and P2) for removal, cleaning, or repair with the two parts coupled and held together during use preferably by an easily operated coupling device (11, 12).

摘要： The gas container valve has a valve body (4) with a detachably mounted valve head (5) which by means of a valve spring (6) is pressed against a seat (3) of a bushing (7) screwed into the housing (2) of the gas container valve. The valve body has at its other end a second valve head (8) which when the bushing (7) is unscrewed is pressed against a second valve seat (9) of the valve housing (2) by the valve spring. Thereby, it becomes possible to replace/repair the first valve seat (3) and/or the first valve head (5), while the gas container valve is mounted on a gas container containing gas under pressure.

摘要： A backflow preventor with increased performance, and increased ease of installation is provided. The check valves (12, 14) are configured to assist in redirecting flow along the desired pathway, when they are in the open position. The pathway is designed so that the number of changes of flow direction of the average streamline flow is reduced, preferably being about 180 degrees. The check valves (12, 14) are configured to reduce or eliminate divergent flow around the edges of the valve disks (32, 72). A check valve (12, 14) with a reduced hold-open pressure includes a biasing device, such as a spring (52, 74) directly connected to a pivoting clapper (32, 72) at one end (64, 66) and to the valve body at the other end (66, 64). No intervening pivoting links are used between the spring (52, 74) and the clapper (32, 72). Preferably, the clapper (32, 72) is connected only by being pivoted (43, 43') to the valve body and by the spring (52, 74) connecting it to the valve body.
