Abstract

1,126,701. Valves. SWACO Inc. 28 April, 1966 [6 May, 1965], No. 18752/66. Heading F2V [Also in Division G3] A throttle for the flow of mud from an oil well has a casing 11, Fig. 1, housing a cylinder 22 of resilient material e.g. rubber or neoprene, with a through passage 21 in alignment with the flow piping 15, 27. The ends of the cylinder 22 are banded to an abutment 20 and a piston 23, the latter housing a tube 30 which passes through a packing gland 31 in a fixed partition 25. Fluid introduced into a space 33 between the partition 25 and the piston 23 causes axial compression of the cylinder 22 and the crosssection of passage 21 is reduced and takes the form of two chokes in series. The cylinder is made longer than necessary to take account of erosion or abrasion. The piston may be actuated by a hand-wheel incorporating a nut coacting with a threaded axial tube connected to the piston; the threaded tube through which the mud flows passes into a separate casing with grooves that prevent rotation but facilitate axial movement of the tube. In another form, the cylinder 79, Fig. 6A, has one end banded to a tube 84 threaded to the piston 85 and the tube 84 encloses a ceramic liner 86 ; a similar liner 88 is disposed within the tube 87 extending from the piston 85. An anti-friction metal sleeve 89 is located between the casing 71 and a part 79<SP>1</SP> of the cylinder 79 which surrounds the tube 84. Means are provided to facilitate renewal of the liner 86 without the use of a wrench. The sleeve 89 may be integral with the piston and the tube 84 extends over a small part only of the length of the liner 86.
