  • Patent number: 9719686
    Abstract: A flow control device has a duct section with a plurality of damper blocking elements, each having a major plane. The damper blocking elements are pivotably connected to the duct section and movable in a range that is limited to ensure that, when the duct section is mounted in a preferred orientation, the damper blocking element major planes always form an angle of at least 45 degrees from the horizontal throughout the range. The range is such that the plurality of damper blocking elements can selectively close and open the duct. The blocking elements can completely close the duct, for example, to block natural convection.

    Abstract: The present invention relates to an anti-shake flow-limiting cutoff valve, comprising a flow stop valve, a cutoff valve and a check structure. Said flow stop valve comprises a valve body, a valve seat, a piston and a biasing component. The check structure is arranged downstream said flow stop valve to prevent fluid from flowing back. In case of a sudden excessive water flow, the flow stop valve is closed under impact of excessive water pressure to block the water flow. At this time, since the liquid flow in the pipeline is suddenly blocked, the liquid flow remaining in a pipeline downstream the flow stop valve tends to form a reverse flow to impact the flow stop valve, thus shaking the flow stop valve, which may further lead to insufficient close or damage of the flow stop valve.

    Abstract: A major challenge for the general use of “lab-on-a-chip” (LOAC) systems and point-of-care (POC) devices has been the generally complex and need for sophisticated peripheral equipment, such that it is more difficult than anticipated to implement low cost, robust and portable LOAC/POC solutions. It would be beneficial for chemical, medical, healthcare, and environmental applications to provide designs for inexpensive LOAC/POC solutions compatible with miniaturization and mass production, and are potentially portable, using compact possibly hand-held instruments, using reusable or disposable detectors. Embodiments of the invention address improved circuit elements for self-powered self-regulating microfluidic circuits including programmable retention valves, programmable trigger valves, enhanced capillary pumps, and flow resonators.

  • Publication number: 20140151465
    Abstract: A spraying device is provided that includes a cartridge containing a first fluid, the cartridge being removably connected to a sprayer body. The cartridge is oriented such that gravity exerts a downward force on the first fluid. The sprayer body includes a conduit for receiving a second fluid. A valve is coupled to the conduit. The valve allows the second fluid to flow through the valve, thus creating a Venturi vacuum that draws the first fluid out of the cartridge and into the valve to enable the first and second fluids to mix and form an outlet stream. An orifice meters a predetermined amount of the first fluid into the valve to achieve a predetermined ratio of the first fluid to the second fluid. The outlet stream is then dispensed from a spray nozzle.

  • Publication number: 20140144525
    Abstract: The present invention provides an improved pressure relief valve comprising a tubular main body with a pressure relief perforation, a pressure adjustor with an anti-leakage rubber and an anti-reverse member; wherein the main body further comprises air inlet and outlet, a channel between the inlet and outlet and with a through-hole penetrating the main body. The pressure adjustor is mounted on the through-hole and the anti-reverse member is mounted on the outlet. As the inlet is connected to an air pump and the outlet is connected to a filling-article, a pressure value is preset with the pressure adjustor such that when the filling-article reaches the preset pressure value, the anti-reverse member engages the channel to move the anti-leakage rubber of the pressure adjustor upward and the air is released from the pressure release perforation in order to stably maintain the filling-article at an air-filling state within the preset pressure value.

    Abstract: An apparatus for rinsing inverted chemical containers includes two main assemblies, namely a gravity flow valve assembly and a rinse adapter assembly. The gravity flow assembly is inserted into the throat of the container. The rinse adapter assembly is detachably secured to the throat of the inverted container. When the rinse adapter assembly is attached to the throat of the container, the rinse tube of the rinse adapter assembly extends upwardly through the gravity flow valve assembly and into the interior of the container. Rinsing fluid, such as water, is supplied to the rinse tube which sprays the rinsing fluid onto the interior of the container to rinse the chemical residue from the interior of the container. The apparatus may also be used to dilute the liquid chemical in the container so that the diluted chemical will more freely drain from the container.
