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. |
