Abstract
A backpressure regulator for regulating pressure comprises a conduit for channelling a fluid under pressure, a regulator for exhausting the fluid when pressure setting is exceeded, a valve for opening and closing flow of the fluid in the regulator, and a screw for variably setting force of repulsion by rotation. The upper portion of the valve comprises an embedded permanent magnet. The lower portion of the screw comprises an embedded permanent magnet. The permanent magnet of the valve has opposite orientation to the permanent magnet of the screw so that the outlet of the regulator is normally closed by bias due to magnetic repulsion. The valve slidably opens the outlet of the regulator when internal pressure of the conduit exceeds the force of repulsion set by the screw. This invention relates to backpressure regulators, and the principal use of the invention is for regulating pressure.
Description
Description Title = Backpressure Regulator using Magnetic Repulsion Technical Field = This invention relates to backpressure regulators, more particularly to a backpressure regulator with magnetic repulsion.
Background Art = There are many instances where it would be desirable to be able to provide a backpressure regulator for regulating pressure without a mechanical spring.
= A number of patents disclose various backpressure regulators.
= U.S. Patent 4 874 012 discloses "Magnetic operator flow device". A magnetically operated flow device contains a flow responsive magnetically attractable body within a flow passage defining upstream and downstream directions therein.
The body is movable in upstream and downstream directions in the passage. The passage includes upstream and downstream limit positions to define upstream and downstream limits of movement of the body within the passage. Magnetic means are provided to attract the body against the fluid flow within the passage to the upstream limit position. The body constitutes a drag obstruction to fluid flow through the passage and will, therefore, decouple from its upstream magnetically retained position in the passage and move to the downstream limit position when drag forces (i.e. flow) increase to the design limit value.
= U.S. Patent 5 280 806 discloses "Excess flow valve". An excess flow valve comprising a valve body defining a passage for a flow of fluid therethrough, the passage having an inlet and an outlet for fluid, a magnetically attractable closure member movably located within the passage for movement toward and away from the outlet, a seat located adjacent to the outlet for receiving the closure member. A flow restriction assembly is located in the passage for defining at least two flow paths for fluid along the passage, the flow restriction assembly including a retaining member comprising a permanent magnet for retaining the closure member in one of the flow paths and away from the seat whilst there is a flow rate of fluid through the passage which is less than a predetermined rate, the retaining member releasing the closure member when the flow rate of fluid through the passage equals or exceeds the predetermined rate so that the closure member moves toward the outlet to engage the seat and shut off flow of fluid through the outlet.
= U.S. Patent 6 325 354 discloses "Magnetically-actuated fluid control valve". This disclosure provides a valve which is controlled by a magnetic actuator. More specifically, the actuator is a polarized, magnetic actuator, that is, a magnetic actuator containing both a permanent magnet and an electromagnet. The actuator can be an inexpensive commercial relay having a pivoting armature that pushes a compliant diaphragm against a valve seat to close the valve.
= These prior art arrangements do not have a backpressure regulator for regulating pressure using magnetic repulsion force exerted by embedded permanent magnets in a valve mechanism.
Description of the Invention = It is a primary object of the invention to provide a backpressure regulator for regulating pressure.
= It is another object of the invention to provide a backpressure regulator without a mechanical spring.
= It is another object of the invention to provide a backpressure regulator that uses magnetic repulsion force.
= It is another object of the invention to provide a backpressure regulator that has embedded permanent magnets.
= It is another object of the invention to provide a backpressure regulator that has a unisex magnetic connector.
= A backpressure regulator for regulating pressure comprises a conduit for channelling a fluid under pressure, a regulator for exhausting the fluid when pressure setting is exceeded, a valve for opening and closing flow of the fluid in the regulator, and a screw for variably setting force of repulsion by rotation. The upper portion of the valve comprises an embedded permanent magnet. The lower portion of the screw comprises an embedded permanent magnet. The permanent magnet of the valve has opposite orientation to the permanent magnet of the screw so that the outlet of the regulator is normally closed by bias due to magnetic repulsion. The valve slidably opens the outlet of the regulator when internal pressure of the conduit exceeds the force of repulsion set by the screw.
