摘要： A self-contained system to continuously monitor a mechanism (11) used to control or regulate fluid flow and provide a continuing indication of the status or condition of the monitored mechanism (11). A specific form of the invention employs a low frequency sonic-to-electrical transducer (18) that monitors opening and closing of a disk-type steam trap (11). The detected sonic signal is processed and sent to a microcontroller (30) that is programmed to develop a time-based, baseline data set representative of normal operation of the steam trap (11 )in the environment in which it operates. The baseline data set is compared against the data from on-line operations of the steam trap. As the environment and the steam trap (11) operation change during normal on-line operations, the baseline data set is updated to change with the changing environment and the changing steam trap (11) operation.

摘要： A pressure relief valve (14, 14A) has a reciprocable valve member (34, 34A) for seating on an annular seat face (66, 66A) of a nozzle assembly (38, 38A). The nozzle assembly (38, 38A) has an inner seat ring (40, 40A), a radially outer anchor ring (42, 42A), and a flexible connecting member (44, 44A) extending in a generally radial direction between the outer peripheral surface (64) of the seat ring (40, 40A) and the inner peripheral surface of the anchor ring (42, 42A). Upon seating or reseating of the valve member (34, 34A), seal face (36, 36A) contacts the seat face (66, 66A) of seat ring (40, 40A) and flexible connecting member (44, 44A) flexes upon relative movement of the seat ring (40, 40A) after initial contact of the valve member (34, 34A) against the seat ring (40, 40A) thereby to act as a shock absorber for absorbing impact forces.

摘要： A low pressure recirculation valve for cooling a centrifugal pump. A valve casing (12) having a first chamber (14) with an inlet (18) and a recirculation port (22), and a second chamber (16) with an outlet (20). A multiple piece check valve (36) between the first and second chambers permits flow from the first to the second chamber and prevents flow in the opposite direction. A slidable valve stem (23) is coupled to the check valve and extending through the first chamber moves the check valve from open to closed position. Means (42) coupled to the valve stem biases the slidable valve stem and the check valve toward closed position. A recirculation valve means (31-35-35a) operatively coupled to the valve stem opens and closes said recirculation port, said recirculation valve means opening when said check valve is closed and closing when said check valve is open.

摘要： A fluid pressure safety relief system for a pressure vessel (10) having a main valve member (46) seating on a nozzle ring (38) under a mechanical force of a predetermined amount resulting from a calibrated counterweight (54). An operating rod (55) is connected between the main valve member (46) and a piston (74) having one side in fluid communication with fluid pressure in the pressure vessel (10). A fluid chamber (78) is provided on the other side of piston (74) and a fluid passage (84) from fluid chamber (78) has an outlet at its upper end (86) closely adjacent the nozzle ring (38). Upon unseating of the valve member (46) from the nozzle (38) fluid flows from the fluid chamber (78) to increase the fluid pressure differential across the piston (74) to assist in the movement of the main valve member (46) to an open position.

摘要： A fluid pressure relief system and method for a pressure vessel or tank (10) having a normal vent (16) with a first pilot operated safety valve (18) and an emergency vent (62) having a second pilot operated safety valve (25). A vapor recovery line (20) is connected to relief valve (18) and collected at a vapor storage container (21). A manway (22) on the pressure vessel (10) (shown in Figure 2) defines the emergency vent (62) and a main valve member (66) has a counterweight (74) thereon to urge main valve member (66) to a seated closed position on nozzle (60). The first pilot operated safety valve (18) for the normal vent (16) (is shown in Figure 7) and has a T-shaped body (142) with a main relief valve member (172) at one end of the body (142) mounted for movement in a generally horizontal direction and controlled by a diaphragm (176) at an opposite end of the body (142).

摘要： A throttling valve (10) which prevents the deterioration of valve surfaces. The claimed invention comprises a casing having an inlet conduit (13) for introducing a liquid or gas medium into said valve, a conically expanding outlet (15) conduit for expelling liquid or gas out of said casing, and a valve bore (16) for supporting a retractable valve member (26); annular sealing means (32) situated within said housing between said inlet and outlet ports; and a retractable valve member (26) for opening and closing flow between the inlet and outlet conduits, said valve (26) having a contoured nose (42) which slidingly mates with said sealing means, said nose being contoured to direct the flow toward the center of said outlet conduit, said contour (42) being defined by an exponential equation whereby vaporization and cavitation of said liquid occurs away from the plug and walls of said outlet conduit.

摘要： A rotatable valve closure element (14) carries an elastomeric annular seal (32) with respect to a metallic valve body. An adjustable nut (54) is threaded to the valve body and includes a recess (60) for receiving a lower stem (62) of the valve closure member. One or more interference members (70) are spaced radially between the nut and the lower stem, and permit axial movement of the lower stem and thus the annular seals with respect to the valve body, while enabling the valve closure member to freely rotate during normal use of the valve. According to the method of the present invention, the lower stem is positioned within the recess of the nut, interference members are then fitted therebetween, the subassembly is then connected to the valve body and the shaft end interconnected with the valve closure member, and the closure member and seal are then centered with respect to the valve body by rotating the nut, which is then locked in position with respect to the valve body when the desired axial position has been achieved.
