摘要： A pump with high performance and cleanability includes a casing having a smaller volute and a larger volute; a space between an outer circumference of an impeller and a starting end of the smaller volute being greater than that of the larger volute, generating a circulating flow of self-priming water from the smaller volute to the larger volute; and a diffusing part of the larger volute being formed into an upright, cylindrical self-priming water separating chamber guiding the self-priming water from the smaller volute to flow in for air-water separation. An inner circumference part of the casing is formed concentric with the outer circumference of the impeller with a predetermined space therebetween; defining members are protrusively disposed on the inner circumference part of the casing so as to define the shapes of the two volutes; and the self-priming water separating chamber is made attachable to and detachable from the casing.

摘要： The present invention is intended to provide a self-priming centrifugal pump with an excellent self-priming and pumping performance without destroying the nearly complete morphology of the volute type centrifugal pump. The principle of self-priming action that circulates self-priming water by the characteristics of a larger volute and a smaller volute formed around the periphery of an impeller to drive out an air-water mixture produced by vortices generated by the impeller is elucidated in the description of "Double Volute Centrifugal Pump" proposed in JP-B No. 28-3039. Efforts have been concentrated on locally supporting the bottom of a tornado-like cavity formed by a whirling current of self-priming water for centrifugally separating air from self-priming water and secondary technical problems accompanying such efforts could not have been solved. The present invention forms a spiral guide passage (F) in an upper part of a self-priming water separating chamber (e) to lower the rising head of a whirling current of self-priming water, forms a curved passage (d) on the bottom (E) of the self-priming water separating chamber (e) so as to direct most part of self-priming water in the outer portion of the whirling current into a larger volute (v2) or forms a spiral guide passage (G) on the lower cylindrical surface of the self-priming water separating chamber (e) so as to direct most part of self-priming water in the outer portion of the whirling current into the larger volute (v2) to solve technical problems in the prior art and to provide a self-priming centrifugal pump capable of supplying water in a straight current to the following process.

摘要： The present invention relates to a controllable constant flow regulating lift valve of a direct-acting automat ic control type that operates on an operating force derived from the condition of a working fluid, such as valve-inlet pressure prevailing in the inlet passage, valve-outlet pressure prevailing in the outlet passage, variation of liquid level on the side of the outlet and so on. The flow regulating valve comprises a flow regulating valve structure and a slide valve structure for automatic flow restriction control. In the controllable constant flow regulating lift valve, axial thrust acting on the spindle of a lift valve type flow regulating valve structure is balanced such that the constant flow regulating lift valve can be operated for constant flow regulation by a very small power. When the flow regulating valve structure and/or the slide valve structure are clogged with soil, sand and dirt, the internal pressure changes to open the clogged valve for automatic cleaning operation so that the soil, sand and dirt are washed away. This constant flow regulating lift valve is suitably applicable to a variety of industrial fields.

摘要： An automatic-control valve device has a main valve unit, and a pilot valve unit for controlling the main valve unit. The pilot valve unit has a pilot valve A which closes when pressure in a downstream passage on the downstream side of the main valve unit increases beyond a predetermined value, a pilot valve B which opens when pressure in the downstream passage increases beyond the predetermined value. The pilot valve A and the pilot valve B are connected in series by passages through a main valve driving pressure chamber in a section between an upstream passage on the upstream side of the main valve unit and the downstream passage, and cooperate to maintain the pressure in the downstream passage at the predetermined valve. A pilot valve C which closes when the pressure difference across an orifice disposed in a passage extending through the main valve unit is greater than a predetermined value is connected in series to a passage extending across the pilot valve A to limit the flow rate of a fluid in the downstream passage to a predetermined value. The respective valve elements of the pilot valve A and the pilot valve B may be held on a single valve stem. The orifice may be of a variable type. The automatic-control valve device may be provided with a valve means placed in a passage extending across the pilot valve A to open and close the passage according to the variation of a liquid level on the downstream side, and a valve means placed in a passage extending across the pilot valve A to close the passage upon the detection of an abnormal condition by an abnormal condition detecting means.

摘要： The present invention is intended to provide an economically advantageous, high-performance water hammer preventing check valve capable of preventing both water hammer and pressure rise under any pipeline conditions when feed of a fluid is stopped and of easily designed and manufactured. The invention provides a water hammer preventing check valve which opens when a fluid is fed forward and closes when the feed of the fluid is stopped to prevent the fluid from reversing. The check valve has a main valve unit and a bypass valve unit disposed in parallel, wherein the main valve unit has a single main valve element capable of opening and closing an opening defined by an inclined main valve seat disposed between an inlet passage and an outlet passage, constantly biased in a valve closing direction, formed in a shape subject to a low form drag and providing a small inertial resistance, and capable of being substantially completely seated on the main valve seat at the moment the velocity of the inertial flow of the fluid in a discharge direction decreases to naught after the supply of the fluid has been stopped; and the bypass valve unit has a bypass valve element capable of linearly moving in opposite directions to open and close an opening defined by a bypass valve seat disposed between the inlet passage and the outlet passage, and linked to a damping device for damping the linear movement of the bypass valve element so that the bypass valve element may gradually close the opening defined by the bypass valve seat after the start of the reverse flow of the fluid.The bypass valve unit may be provided with an opening adjusting mechanism for adjusting the opening of the bypass valve element. The main valve unit may be provided with a valve closing force adjusting mechanism for applying a valve closing force to the main valve element.
