摘要： A water hammering prevention device including an outer box defining a flow path having an inlet, an outlet and a drain port in a midstream section thereof. An inner tube member has a diaphragm on its periphery dividing the inside of the outer box into an upstream section, and an area consisting of a midstream section and a downstream section of the flow path. A relief valve is provided and is caple of moving toward or away from a valve seat located on the periphery of a valve port provided between the midstream section and the downstream section. A check valve is provided inside the inner tube member to prevent fluid from flowing backward from the downstream side, and to discharge pressurized fluid generated by water hammering to the outside via the drain port.

摘要： A reverse flow prevention apparatus is provided so as to drastically decrease pressure loss without installing an independent pressure regulator mechanism therein. With the reverse flow prevention apparatus, a flow path running along a straight line is provided in an outer box, and is partitioned by a diaphragm into an upstream region, and the downstream of a midstream region. An inner cylindrical body is provided at the center of the diaphragm, integrally therewith, so as to fit slidably into the upstream region of the outer box, an escape valve is provided on the downstream side of the inner cylindrical body in such a way as to be able to freely open and close a valve port provided between the midstream region and the downstream region while the escape valve is energized towards valve opening by the urging of an escape valve spring, and first and second check valves are provided inside the inner cylindrical body and the downstream region of the outer box, respectively. An effective diameter of the diaphragm and a diameter of a valve seat of the escape valve are set substantially at an equal value while a spring load of a first check valve spring and that of the escape valve spring are set such that a pressure of the midstream region is maintained always lower by a predetermined value than a pressure on the upstream side.

摘要： A reverse flow prevention apparatus 1 comprises a housing 2 with two check valves 5, 6 in series, an inner body 3 displaceably mounted upstream of check valve 6 which provides the housing for check valve 5 and cooperates with housing 2 to form the valve member of an escape valve 4 whose outlet is a drain 10 positioned between the check valves wherein a spring 19 urges escape valve 4 into an open position and a diaphragm 17 connects inner body 3 to housing 2. The inner body can be cylindrical. The effective diameters of diaphragm 17 and escape valve seat 14 are equal and the tension of springs 19, 30 are set so that the pressure between check valves 5, 6 is lower than upstream of valve 5. Inner body 3 may slide against housing 3 in an area 15 provided with equally spaced, circumferential, recessed grooves 16 and may be coated with a non-stick coating. Valve members 36 may be substantially mushroom shaped. Inner body 3 may have a tapered end 39. External linkings 11, 11a, 11b, opened by ball valves 12, 12a, 12b, may be provided to all three sections 9a, 9b, 9c of the apparatus 1.

摘要： To discharge, along with drainage, all of the foreign matter mixed in water to be supplied regardless of whether the water to be supplied is clean water or recycled wastewater without using a built-in strainer. [Solution Means] In a ball tap 1, a valving element 3 includes a valve part 10 provided with a contact projection part 9 that can come into close contact with a valve seat 7 when the valving element 3 is closed, and a flange part 11 having a circular ring shape in plan view which continues downward from the rim of the valve part 10 and is slidable like a piston in the secondary side flow passage 5, and the left and right half circumferences of the upper surface of the flange part 11 have bilaterally symmetrical shapes curved downward in arch shapes, and the left and right lower limit portions of the upper surface of the flange part are set so as to be positioned at the same heights as those of the lower end edges of drainage ports 8 formed to expand on the left and right of a secondary side flow passage 5 or slightly higher than the lower end edges when the valving element 3 is fully opened.
