    Abstract: The present invention concerns a valve (1), a valve closing body (14) and use of a valve (1) and a valve closing body (14) of the type used for injecting dry powder which is mixed with liquid, and where the dry powder is supplied under the liquid surface in a mixing vessel (11) in which a vacuum is typically maintained. The novel feature of a powder valve (1) according to the invention is that a closing body (14) of the valve in the closed position extends through the valve seat (13) of the valve and into the wet environment. It is hereby achieved that when the valve (1) is opened, powder or dust from powder is not deposited on the valve closing body (14). This is in spite of the valve closing body (14) being wet, due to contact with the liquid to which the powder is added. Due to its elongated shape, the valve closing body (14), which in the withdrawn position opens for inflow of powder, has the property that the inflowing powder dries the valve closing body (14) at first and keeps it dry subsequently.

    Abstract: A needle valve that adjusts the flow of liquid fluid and an open/close valve that makes it possible to fully close a flow path of the liquid fluid are accommodated inside a casing of a flow adjusting valve. The needle valve is provided with a reciprocating movement section that adjusts the flow of the liquid fluid by moving a needle valve piece toward and away from the valve seat. The open/close valve is provided with an opening/closing section that utilizes a basal outer surface of the needle valve piece facing the valve seat as a fully-closing valve piece and that reciprocatingly moves the fully-closing valve piece, independently of the reciprocating movement section, between a closed position, where the fully-closing valve piece is in close contact with the valve seat, and an open position, where the fully-closing valve piece is moved away from the valve seat.

  • Patent number: 8727307
    Abstract: A valve has a first duct and a second duct at right angles to the first duct. The first duct opens into a connecting portion of the second duct, defining an intersection that forms a seat for a valve disk that slides in the connecting portion in a direction at right angles to the seat between a closed position and an open position. The connecting portion has two flat walls facing one another and connected by an end wall. The first duct opens onto one of the flat walls. The end wall partially surrounds the valve disk parallel to the a direction of sliding at a distance from an edge of the valve disk that is such that, for the open position, the end wall defines with the edge of the valve disk and the seat a passage.

  • Publication number: 20140103236
    Abstract: Disclosed in the invention is a throttle valve, which comprises two sealing elements whose contact surfaces keep in sealing and matching state, the two sealing elements can move relative to the valve. An inlet (111, 211, 311) and an outlet (121, 221, 321) of the valve are provided on the two sealing elements (11, 21, 31, 12, 22, 32), respectively. A semi-conical adjusting chamber (112, 212, 312, 122, 222, 322) is provided on each of the contact surfaces of the two sealing elements. The sharp ends of the adjusting chambers face to each other and communicate with the inlet and the outlet, respectively. When the contact surfaces of the two semi-conical adjusting chambers overlap at least partly, the two adjusting chambers constitute a passage communicating the inlet with the outlet. The throttle valve can realize greatly proportionally and accurately adjusting, is pressure resistant and wearable, and is suitable for use in slurry delivery pipelines and liquid or other fluid delivery pipelines.

  • Patent number: 8678345
    Abstract: A temperature control system for a gas appliance utilizes an improved variable orifice gas flow modulating valve capable of direct modulation of gas flow through an orifice directly into a gas burner to provide a constantly maintained temperature in an appliance working compartment, as selected by human interface via a temperature selector. An actuator attached to a gas fitting body of the valve provides for linear movement of a metering pin into the taper inside the orifice, accomplishing the variable controlled modulated flow of gas directly into the burner. The actuator is controlled by an input signal from a programmable controller whose output is determined by calculations based on inputs from a temperature selector and a temperature sensor located in the gas appliance working compartment.

  • Patent number: 8662470
    Abstract: A dental syringe may include a replaceable valve cartridge containing one or more valves which may use a seating surface and an opposing seating surface with a relative angle formed between the two surfaces. The relative angle allows for regulation of the flow of fluid. The replaceable valve cartridge may also include a system to remove a residual liquid from a tip of a dental syringe. Additionally, the replaceable valve cartridge may include a seal that prevents bleed-over of fluids. Further, the dental syringe may comprise a tip retention insert which may use either a pair of plates or a plurality of ball bearings to retain the dental syringe tips. An alternate embodiment of a valve may comprise features intended to reduce the force necessary to actuate the valve. A metering screw and/or flow-control groove with increasing depth may control of flow through the valve.

  • Patent number: 8568371
    Abstract: A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet and an outlet, a rigid member movably mounted within the housing, and a resilient member with a sealing portion. The housing also has at least one relief zone that is in fluid communication with the outlet when the valve is in the closed mode. The rigid member may have a proximal end, a distal end, and a flow channel. The relief zone may be radially outward from the sealing portion. The sealing portion may seal the valve and prevent fluid from passing through the valve when in the closed mode.
