Problems solved by technology

While these practices are useful in some respects, such as avoiding possible contamination of water or other fluids by the drive lubricant, some essentially external structures have created some pressure imbalance and / or drag relative to the seals or packing, resulting in many High effective operating (gate opening or closing) torque

Embodiment Construction

[0012] Before describing the features of the present invention, certain aspects of a multiport sleeve valve consistent with previous practices will be described. exist figure 1 In its construction, the inlet housing 112 substantially surrounds a generally cylindrical sleeve member 114 having a number of orifices or nozzles 116 through the sleeve wall on an upstream portion thereof. The downstream portion of the sleeve forms fluid communication with the valve outlet 118. An annular valve gate or ring 122 can be sealingly arranged to cover some of the nozzles 116, as shown, and can also be moved in an upstream direction 124 to cover substantially all of the nozzles 116, or downstream direction 126 to open substantially all nozzles 116. When at least some of the nozzles 116 are open, an inlet liquid flow 128 (often at high pressure) is received via the inlet orifice 132 and spreads out around the nose piece 134 . High pressure liquid exits the (low pressure) outlet orifice 118...

Abstract

A sleeve valve is driven by a threaded rod (244) and nut (246).

Description

technical field [0001] The present invention is directed to a type of multi-port sleeve valve that can be used for flow control and pressure dissipation, and is particularly concerned with a reduced length compared to at least some prior constructions. Background technique [0002] Multi-port sleeve valves are used in many applications, including flow control and pressure dissipation applications, such as those requiring the reduction of high inlet pressure to a lower maximum outlet pressure over a relatively wide range of flow rates. For example, multi-port sleeve valves can be used to accommodate flows in the range of 0 to 250 cubic feet per second (cfs) at pressures of approximately 85 pounds per square inch (psi) or greater, and output at pressures up to 12 psi . A description of one type of multi-port sleeve valve can be found, for example, in US Patent No. 4,508,138, issued April 2, 1985, which patent is incorporated herein by reference. Some types of sleeve valves h...
