Abstract

The invention belongs to the field of energy conversion control, and relates to a sealing reversing valve which comprises a cylinder body, a reversing piston assembly and an executing mechanism. A pressure boosting hole is formed in the cylinder body, and a pressure relief groove is formed in the reversing piston assembly. According to the sealing reversing valve, the water pressure inside a waterpressure cylinder is boosted in advance through the pressure boosting hole, a low-pressure inlet check valve is slowly closed, and the problem of quick knocking of the low-pressure inlet check valveis solved, and the service life of the check valve is prolonged; high-pressure water flow in the water pressure cylinder is depressurized in advance through the pressure relief groove, water hammeringcaused when large-flow high-pressure concentrated water makes instant contact with low-pressure concentrated water is avoided, equipment vibration is avoided, and equipment operation noise is lowered. The invention further relates to an energy conversion device comprising the sealing reversing valve.

Description

technical field [0001] The invention belongs to the technical field of energy conversion control, and in particular relates to a sealed reversing valve and an energy conversion device. Background technique [0002] As we all know, reverse osmosis membrane separation technology is a separation technology that utilizes the difference in selective permeation performance of each component in the mixture to separate, purify, concentrate and reduce. Reverse osmosis is a membrane separation method that uses pressure difference as the driving force to separate the solvent from the solution. It applies pressure to the feed liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will go against the direction of natural penetration. For reverse osmosis, the permeated solvent is obtained on the low-pressure side of the membrane, that is, the permeate, and the concentrated solution is obtained on the high-pressure side, that is, the concentrate. ...
