摘要： A double check valve is provided that includes an in-line inlet check valve and an outlet check valve that cooperate to prevent back flow of fluid through the valve. The check valve also includes at least one vent that allows for fluid trapped within the check valve to drain, thereby preventing freezing of the check valve and hydrant to which it is interconnected. The check valve provided omits many superfluous components and thus is smaller and easier to install than check valves of the prior art.

摘要： An actuator system for a fluid playground including a first elongated tubular member defining a first axially extending enclosure and having a first inlet connectable to a fluid source, and a second elongated tubular member positioned within the first tubular member, the second tubular member defining a second axially extending enclosure, and having a second inlet in fluid communication with the first enclosure and an outlet traversing the first tubular member. The outlet is connectable to at least one fluid playground device. A plug element is shaped to removably and sealably close the second inlet of the second tubular member. A resilient member urges the plug element towards sealing engagement with the second tubular member. A pressure exerted on a movable actuating element connected to the plug element causes its displacement away from sealing engagement with the second inlet, thereby allowing fluid flow to the fluid playground device.

摘要： The present invention relates to apparatuses, systems, and methods that manage the flow of fluids, such as, for example, water, through pipes. Specifically, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe when the fluid meets a spring loaded poppet valve, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid. The pressure in front of the poppet valve builds and moves the poppet valve away from a seat allowing the fluid with compressed gas bubbles to flow therefrom, which provides more accurate water meter measurements because less gas is being considered in said measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for managing fluids are further provided.

摘要： A hydraulic control valve actuated by a diaphragm's integral spring whose thicker part acts with greater force to close the diaphragm and plug unit of the valve and whose thinner part may complete the closing motion so that the integral spring may weaken faster than linearly in relation to displacement of the diaphragm and plug unit. A snap seat supporting the plug may include a seat portion and a grip skirt portion integrally joined at an acute angle. A bracket and sliding guide may guide a helical rotor touching an indicator. Movement of the diaphragm and plug unit may rotate the helical rotor and the indicator without the indicator rising out of the valve. The cover may have an internal control passage in communication with a base of the valve to allow the cover to be installed horizontally and vertically conveniently and without disconnecting the control tubing above the valve.

摘要： A compressor lubrication system including a positive displacement pump, a pressure relief valve assembly, and a divider block. The pressure relief valve assembly includes a housing that has an opening to the fluid distribution system and a relief passage. A conduit is connected from the relief passage to a fluid reservoir. The assembly also includes a pressure relief valve that has an open position in which fluid from the fluid distribution system can enter the relief passage, and a closed position in which fluid is prevented from entering the relief passage. A biasing element maintains a biasing force on the pressure relief valve. The pressure relief valve is maintained in the closed position when the biasing force exceeds the fluid force on the pressure relief valve and the pressure relief valve moves into the open position when the fluid force exceeds the biasing force.

摘要： Devices and methods for extracting a beverage from a container, such as a wine bottle. Beverage can be extracted from a container by inserting a needle through a container closure, such as a cork, delivering pressurized gas into the container via the needle, and dispensing beverage from the container via the needle. A pressure regulator may control a pressure of gas introduced into the container, and a lance used to pierce a pressurized gas cylinder may include a leading face arranged to reliably pierce a cylinder closure. The regulator may include valve features to reduce valve chatter or hammering and provide a more reliable pressure seal.
