摘要： 1,188,153. Valves. M. H. GROVE, and J. M. E. GROVE, [trading as M. & J. ENG. CO.]. 4 May, 1967 [9 May, 1966], No. 20705/67. Heading F2V. Leakage past the upstream seat of a gate valve 10 is detected by closing switch 47 at remote station 37 to vent the interior of the valve 10 through valve 38, and then closing the latter and closing switch 46 such that any rise in the internal pressure is sensed at 39 and indicated at 44. Valve 38 may be replaced by a three-way three-position valve (51) which can connect the interior of valve 10 to exhaust or to the inlet duct or to neither of these. The gate valve seats (Fig. 5) comprise a nylon ring 73 mounted in a groove in a spring- loaded carrier ring 74. Ring 73 carries a softer ring 76 and a seal ring 77.

摘要： 1,222,529. Valves. M. H. GROVE, and J. M. E. GROVE, [trading as M. & J. DEVELOPMENT CO.]. 23 Oct., 1968 [30 Oct., 1967], No. 50233/68. Heading F2V. . A valve comprises sealing means 18 in the form of an annular rigid seat member 21 carried by the body 10 and sealed therewith (as at 29), the member 21 having a surface adjacent a valve working surface, an annular recess housing a ring of non-metallic resilient material 39 (e.g. nylon) having a face disposed to contact the valve working surface, and an annulus of non-metallic material 52, more resilient than the material 39 (e.g. rubber). The valve is provided with aligned fluid passages 11 and a gate 13 with a port 14. Surrounding each passage 11 is the annular member 21 carrying on its inner periphery circumferentially spaced springs 31. The springs are partially compressed by an inner ring 33. Preparatory to an assembly operation, it is desirable to heat and soften the nylon ring 39 by immersion into boiling water. After a suitable semi-fluid bonding cement is applied to the recess, the ring 52 is snapped over the inner surface of the recess. The nylon ring is forced into the recess and machined together with the ring 52 for engagement with an adjacent gate 13.

摘要： 1,219,726. Valves. M. H. GROVE, and J. M. EMERY, [trading as M. & J. DEVELOPMENT CO.]. 5 May, 1969 [7 May, 1968], No. 22786/69. Heading F2V. Leakage of fluid past the seals in a gate valve is detected by venting the upper part of the valve chamber for a predetermined time after the valve has closed, and then detecting any rise in pressure in the chamber. Pressureresponsive switch 22 and solenoid operated valve 21 communicate with the chamber through pipe 24 which extends through chamber wall 26. Timer 23 has a heated bi-metallic strip element 32 which operates change-over switch 34, and a switch 36 is closed automatically when the gate valve closes. In operation, closure of contacts 36 initially establishes circuits through element 32 and the solenoid of valve 21 which is thereby opened. After a time determined by element 32, switch 34 de-energises the solenoid and establishes a supply through line 45 to the contacts of switch 22 so that in the event of a pressure build up in the chamber, an indicator lamp 57 is energized through line 47 and circuit blocks 56, 52. A switch 61 shunted across switch 36 enables the apparatus to be cycled without moving the gate. Sixteen valves are connected to a common indicator lamp 57 which, with switch 54 closed, lights up for a fault in any of the valves. By opening switch 54 and operating stepping switch 58 the particular valve at fault can be identified. The gate valves are operated by pneumatic cylinders 11 controlled through relay valves 66, 74 and 74. Specification 1,188,153 is referred to.

摘要： 1299695 Valves M H GROVE and J M E GROVE [trading as M & J DEVELOPMENT CO] 19 April 1971 [29 April 1970] 25936/71 Heading F2V A fabricated gate valve body includes end plates 11 welded to sideplates 12 and reinforced by pairs of ribs 26 each of which abuts the respective endplate at 27 and has a central portion 28 welded to the endplate at 29. The ribs 26 of each pair are welded at 33 to slotted tie plates 31 which in turn are welded to the side plates 12. The central portion 28 of each rib 26 is initially spaced from the adjacent endplate 11 so that weld 29 establishes a prestress. Auxiliary ribs 36 can be welded to the tie plates, and C-shaped clamp bars (39) can extend across the sideplates 12 and embrace the edges of the endplates 11, where they are welded in place. The arrangement resists inward and outward deflection of the endplates.

A gate valve comprises a body 11, 14 having mounted thereon a bonnet 18, 21, 23 through which an operating stem 24 for the gate 27 extends, and sealing means including a rigid bushing 34, e.g. of metal, which is so mounted with machined clearances in the bonnet as to permit universal self-aligning movement in relation to the stem. The stem is sealed by 0-rings 38 of relatively hard resilient material such as nylon. The backing is also sealed to the bonnet by an 0-ring 39 which may be of synthetic rubber or other elastomer. As shown, the bonnet includes a plate 18 sealed to the body flange 14 at 41, and a flange 21 sealed at 42. In a modification the seals 39 and 42 are replaced by a seal between the bushing 34 and the plate 18. Sealant is supplied to the stem through a pipe 40. The valve may be manually operated or the part 23 may form the cylinder of a piston actuator.

摘要： Meter-proving method and apparatus for calibrating liquid flow metering devices. It employs a metering pipe or loop through which the flow is diverted. A plug or sphere is launched into the inlet end of the pipe and is propelled through the pipe by the liquid flow during a proving run. A special sphere-launching device is provided to launch the sphere into the inlet end of the metering pipe, and also to retain the sphere after it has cleared the pipe, whereby it is ready for the next prover run. This device is constructed to establish seals between the inlet and outlet ends of the proving pipe during and after a run. Its inner shuttle part is movable between sphere retaining and launching positions, and in both positions line flow occurs directly through the device. The inner shuttle part can be withdrawn for replacement of a sphere. Leak detecting means is associated with the seals of the device to detect any leakage.

摘要： 1,263,854. Temperature compensation in melting. M. H. GROVE and J. M. EMERY [trading as M. & J. DEVELOPMENT CO.]. 7 April, 1970 [11 April, 1969], No. 16327/70. Heading G4H. To compensate for variations in the temperature of a fluid the flow of which is being metered, pulses representing the fluid flow (on conductor 23, (Fig. 1)) after shaping are fed to a gate 32 receiving a reference voltage corresponding to a reference temperature so that negative pulses at the reference voltage and at a rate dependent on the fluid flow are fed to a differential amplifier 37, the amplifier also receiving pulses at the same frequency but at an amplitude dependent on the temperature of the fluid determined by a probe 36. The amplifier output is integrated using an operational amplifier 56 and integrating capacitor 57, subtraction and addition level detectors 41, 42 being operated when the ramp output on conductor 59 reaches predetermined positive or negative levels to operate gates 15, 17, the gates receiving on their other inputs pulses representing fluid flow. Operation of gate 15 results in a pulse being inhibited and operation of gate 17 results in a pulse being added so that the pulse train output at terminal 19 is temperature compensated. After the level detectors are triggered the integrating capacitor is discharged. The gain of amplifier 37 may be adjusted by means of resistor 55 to compensate for different thermal coefficients of expansion of different liquids.
