摘要： A valve box (6) comprises a main valve (2) clamped between a pair of pipe flanges fastened with bolts (B,B1) and nuts (N,N1). The connection edge of the pipe flange (F) has an inlet port (7) and exit (8) for pressure fluid, which passes through a space extended upwards from the valve box. A cover flange neck (18) inserted between the bolts adjoining the periphery of pipe flange so that sidewall of the cover flange neck corresponding to each bolt is formed in narrow width.

摘要： A valve assembly uses a pilot valve 3 to operate a main valve 2. A valve body 6 enclosing the main valve 2 is sandwiched between pipe flanges F, F1 secured by nuts and bolts (B, B1, Fig. 3). The valve body 6 is flangeless at its end portions 11, 12 where it abuts the pipe flanges F, F1 and has an inlet 7 and outlet 8 for a pressurized fluid. A flange neck 18 extending upwardly from the valve body 6 has restricted side walls to allow space for the passage of the bolts (B, B1, Fig. 3).

摘要： In the direct-acting valve of the present invention, no flange is formed in the valve box and the piping is achieved by interposing the valve box between pipe flanges. The direct-acting valve of the present invention includes: a driving section 1 that operates by sensing a primary pressure or a secondary pressure; and a valve body 3 communicating with the driving section 1 to open and close a flow path 2. A valve box 4 of the valve is sandwiched between pipe flanges F and F1 tightened by bolts B, B1 ... and nuts N, N1 .... connecting end portions 10 and 11 to be mated with pipe flanges F and F1 that respectively have an inlet and an outlet 6 and 7 of the flow path 2 are made to be flangeless. A cover flange neck 17 is extended upward from the valve box 4 is formed so as to be interposed between the bolts B and B1 which are provided between the pipe flanges F and Fl and adjacent to each other on the circumference of the pipe flanges F and F1.

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.
