摘要： The invention has its object to radically resolve an untapped technical issue in a non-water hammering check valve device, in which a valve disc, a valve seat and a surrounding flow passage are configured such that the valve disc is substantially seated on the valve seat at the time when input to a pump is shut off and a discharge flow in the flow passage loses inertia to stop, and to provide a reasonable non-water hammering check valve device of a simple and clear construction which suffers a small resistance loss of a valve at the time of a predetermined maximum flow rate, can readily accommodate an abrupt change in a flow state without delay in valve closing operation and provides a uniform and close seating on the valve seat at the time of valve seating to prevent water hammering. In the non-water hammering check valve device, a valve disc (4) is connected to an arm portion (5) through a valve disc support shaft (6) with a required freedom of swinging, and the arm portion (5) is connected to a valve body (1) through an arm support shaft (7). At the time of valve opening, the valve disc (4) is caused by an additional acting force, which turns the valve disc (4) about the valve disc support shalt (6), to be floatingly supported in the flow passage while an upstream end (4a) of the valve disc and an upstream end (5a) of the arm portion preferentially abut against each other all the time. At the time of valve closing, a downstream end (4b) of the valve disc preferentially abuts against a valve seat (3), and in a subsequent valve seating stroke, the entire surface of the valve disc (4) comes into uniform and close contact with the valve seat (3) to prevent water hammering caused by counterflow.

摘要： A self-sucking centrifugal pump capable of displaying excellent self-sucking and pumping performance without changing the shape of a volute type centrifugal pump which already has a nearly perfect shape. The basic principle of a self-suction operation in which a gas-water mixture is pumped by a vortex current generated in a vane wheel by circulating self-sucking water by utilizing the characteristics of larger and smaller volute chambers formed in an outer circumferential portion of the vane wheel is clearly disclosed in Japanese Patent Publication No. 3039/1953 entitled "Double Volute Chamber Type Centrifugal Pump". In a conventional centrifugal pump of this kind, those skilled in the art were intent on supporting a tail portion of a whirlwind type hollow, which occurs due to a self-suction swirl current for the gas-water centrifugal separation, on a limited part, and could not solve the new derivative technical problems. The present invention has first solved the technical problems definitely by forming in an upper portion of a self-suction water separating chamber e a helical guide flow passage F extending in the direction in which a rising part of a liquid surface occurring due to the centrifugal force of a self-section swirl current is wound down; forming in a bottom portion E of the separating chamber e a wind-out flow passage d extending in the direction in which an outer circumferential portion of the self-suction swirl current is introduced preferentially into a larger volute chamber v2; and forming in a cylindrical wall surface at a lower portion of the separating chamber e a helical guide flow passage G extending in the direction in which an outer circumferential portion of the self-suction swirl current is introduced preferentially into the larger volute chamber v2, the present invention having obtained a self-section type centrifugal pump capable of sending a set current advantageous for a subsequent stage to the same stage.

摘要： The present invention provides a high-performance, economically advantageous filter device of a simple, rational construction capable of easily removing foreign matters deposited on a screen and discharging the foreign matters removed from the screen by either manual operation or automatic operation using actuators A self-gush-cleaning filter device comprises a filter casing (1) provided with an inlet passage (a) and an outlet passage (d), a screen (11) disposed within the filter casing (1) so as to slide along the inner surface of the filter casing (1) in the flowing direction of a fluid, a foreign matter ejecting opening (15) being formed between the screen (11) and the inlet passage (a), a drive shaft (4) for driving the screen (11), a screen driving unit (3) for driving the drive shaft (4) so as to move the screen (11) quickly in a downstream direction in which the fluid flows from the inlet passage (a) toward the outlet passage (d) and to move the same slowly in an upstream direction opposite the downstream direction, and an outlet shutoff valve (14) disposed in the outlet passage (d) of the filter casing (1). The screen driving unit (3) is actuated after closing the outlet shutoff valve (14) to move the screen (11). When the screen (11) is moved quickly in the downstream direction, the fluid gushes from the downstream side through the screen (11) into the upstream side, and the foreign matters deposited on the screen (11) are removed from the screen (11) by the force of the gushing fluid.

摘要： The invention provides a reasonable, non-water hammering check valve device which radically dissolves a technical problem unsolved in conventional, non-water hammering check valves, is simple and precise in construction to provide less valve resistance loss at a predetermined maximum flow-rate, and in which, when input to a pump is cut off, a valve disc can readily respond to rapid status changes in flow to be free of delay in valve closing movement, and when flow in a flow passage in a direction of discharge loses inertia to stop, the valve disc substantially comes into contact with the valve seat and gently contacts with the valve seat at that time to prevent water hammering and impulsive sounds. In the check valve device, the single-lobe valve disc and the valve seat are constructed so as to easily follow up movements of passing fluid, the valve disc is connected to a braking device through a linear movement transmitting mechanism, and the braking device and the movement transmitting mechanism are constructed to entirely eliminate influences such as braking and friction on actuating portions and sealing portions which cause deceleration of valve closing movement during a period from the valve closing starting by the valve disc to immediately before valve seating, whereby gentle braking is limitedly effected in a short period from immediately before valve seating to the valve seating to prevent water hammering and impulsive noise at the time of valve seating. Further, timing of valve seating can be adjusted by means of a braking start position adjusting portion, a bypass adjusting valve of the braking device, adjustment of biasing forces of a valve closing biasing member and the like.
