Abstract:
A fluid dispenser system is disclosed that can have a plurality of dispensers, each having a valve. Each valve can be connectable in series with another valve. The dispenser system can include a manifold permitting passage of a common fluid therethrough. Any of the valves connected to two adjacent valves can be removable without removing either of the valves to which it is connected. The common fluid can have a fluid pressure associated therewith. The fluid pressure can generate a tension force for pushing two adjacent valves apart and thereby lock the valves into a series connection. A method of removing a valve from a series of valves comprises stopping flow of the common fluid through the manifold, thereby releasing the tension force. The valve intended to be removed can be rotated, and thus removed with respect to the valve intended to be left in the series connection.
Abstract:
Disclosed is a fluid path network (100) comprising plural fluid paths (110) interconnected by plural nodal chambers (120), three or more of said plural paths opening into each of said chambers, and said chambers being adapted the accept a removable fluid path modifying insert (130/140/150 Figs 3a-3c). The network is employed in a chromatography system described herein.
Abstract:
A refrigerant valve arrangement (1) is shown comprising a housing (2) having an inlet (3) and an outlet (4) and defining a main flow direction (5) a first valve having a first valve axis (11), and a second valve having a second valve axis (17). Such a refrigerant valve arrangement should have a low pressure drop between inlet and outlet. To this end said first valve axis (11) encloses a first angle (a) smaller than 90° with said main flow direction (5) and/or said second valve axis (17) encloses a second angle (β) larger than 90° with said main flow direction (5).

Abstract:
Provided is a combined valve block for controlling a fluid in which flow path grooves and cross grooves of a flow path plate and an adjustment path are separately manufactured for different flows of the fluid and a distance between flows is minimized by combining and assembling a flow rate plate, the flow path plate, and the adjustment path, thereby minimizing a dead volume of the fluid that occurs in a distance between valves and achieving smooth flows.
Abstract:
A valve body (100, 100', 100") for safety valves adapted to adjust a pressure in a tank of fluid, the valve body defining a cavity (105) inside the valve body is proposed. The valve body comprises: a plurality of openings (110a, 110b, 110c, 110d) provided in the valve body (100) to allow accessing the internal cavity of the valve body, at least two openings (110a, 110b, 110c, 110d) of said plurality of openings being provided on the valve body in such a way to lie on substantially parallel planes one with respect to the other, and a plurality of mechanical coupling portions (120a, 120b, 120c, 120d). Each mechanical coupling portion is provided in correspondence of a respective one of said at least two openings of the valve body, and each mechanical coupling portion is adapted to couple with a corresponding coupling portion of a further valve body.
Abstract:
A coupling valve (1) has two parts (2, 3) each having a fluid conduit (5, 21) and a valve closure disc (6, 8). The discs (6, 8) are on shafts (7, 9), each being at is 45° to its respective shaft. The valve discs (6, 8) and their shafts (7, 9) are lined, as are all fluid-contacting surfaces. The discs (6, 8) are configured to press together when the parts (2, 3) are coupled and to move together between closed and open valve positions. The movement is by rotation of one (7) of the shafts as a master shaft, drive being transferred to the other disc (8) by virtue of a friction fit under a compression load applied by a coupling mechanism (15). An O-ring (60) assists the dry seal between the valve discs (6, 8).
Abstract:
Device for limiting or keeping constant a quantity of fluid flowing therethrough, comprising: a housing which comprises a front chamber and a rear chamber; a partition arranged in the housing and provided with two or more openings; and a flow limiting element arranged in one or both openings, the flow limiting element comprises the following: a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate -like valve element which is mounted in the housing and which can substantially close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening, wherein the valve element is fixed on one side and the valve element can move resiliently on the opposite side in the direction of the valve seat. Mould for producing one or more injection-moulded products, wherein at least a part of the mould is movable and adjustable from the outer side such that the size and/or the shape of the mould cavity is adjustable. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough, comprising: a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate -like valve element which is mounted in the housing and which can substantially close the throughflow opening by resilient movement in the direction of a valve seat arranged adjacency of the throughflow opening in the housing, wherein the valve element is fixed on one side and the valve element can move resiliently on the opposite side in the direction of the valve seat.
