Problems solved by technology

[0005] However, it is important that the operating system used to open the valve is not used to reduce the valve's efficiency by changing the valve's opening speed or opening period
If by reducing the operating pressure, the overall efficiency of the valve is reduced, the end result of the system will be less satisfactory

Embodiment Construction

[0030] refer to figure 1 -5, poppet valve 10 is shown having a valve body 12 with an inlet side 14 and an outlet side 16 . A valve seat 18 is defined on an end face of the body 12 at its inlet side 14 and is adapted to be engaged by a poppet valve closing member 20 which slides within the body between a closed position and an open position. exist figure 1 In and 3, the valve is shown in its open position.

[0031] The valve body 12 has a generally hollow cylindrical configuration and a flow passage 22 is defined through the valve body connecting the end at 14 and the outlet 16 . When the valve is open, the flow passage 22 is substantially unobstructed, allowing high pressure air or the like to be exhausted from a pressure vessel (not shown) in which the valve is mounted with minimal pressure drop across the valve. The valve is provided on its outer surface with a mounting flange 24 for mounting the valve in place in the manner described in patent application PCT / AU02 / 01716....

Abstract

A valve of the invention includes a valve body having an inlet, an outlet, and a flow passage connecting the inlet and outlet, the inlet, the outlet and the flow passage being in general axial alignment within the valve body. A valve seat surrounds the flow passage and a valve closure member is movable towards and away from the valve seat to close and open the valve respectively. The valve closure member is a poppet-type closure member axially mounted to a stem. The stem has a plurality of pistons spaced apart along the length thereof, and the valve body has a plurality of cylinders fixed relative thereto, the pistons each being slidable in a respective cylinder. The valve closure member is movable by varying the pressure in the cylinders. Preferably each of the cylinders has an outlet port through a wall thereof which is exposed when the closure member has moved towards or into a fully open position, pressure within said cylinders dissipating through those outlet ports when the outlet ports are exposed.

Description

technical field [0001] The present invention relates to a flow control valve that can be opened and closed quickly and by which the timing of the opening cycle can be controlled relatively accurately. The invention will be described with particular reference to a flow control valve for backpulse cleaning of filter elements, but it should be understood that the invention can be used in a wide variety of other applications. Background technique [0002] Applicant's co-pending patent application No. PCT / AU02 / 01716, incorporated herein by reference, describes a poppet valve for reverse pulse cleaning of a filter element using a reverse pulse of relatively low pressure air. Low pressure high volume pulses provide effective cleaning pulses and have a wide range of applications in the filter cleaning industry. The valves described in this specification use high pressure operating fluids to open and close the valves. [0003] The efficiency of a backpulse cleaning system is determ...
