Abstract

The invention discloses an electric reversing control valve for oxygen production and a control method. The electric reversing control valve for oxygen production comprises a valve seat, a sealing mechanism and a gear driving mechanism. The valve seat is divided into four sealing cavities including two public cavities, a vacuum cavity and a pressure cavity. The sealing mechanism is composed of a guide rail, a rack, a sealing seat and a sealing ring. The gear driving mechanism is composed of a driving wheel and two driven wheel assemblies, and the driving wheel is connected with a driving motor through a key. The driven wheel assemblies of the gear driving mechanism are driven by the driving wheel to rotate in the opposite directions, so that the rack of the sealing mechanism is driven to linearly move in the opposite directions. And the sealing seat of the sealing mechanism is connected with the rack and does linear motion in different directions along with the rack, so that the pressure cavity / vacuum cavity is communicated with the different public cavities, the switching of the working states of the control valve is realized, and the vacuum and pressure can be exchanged and output.

Description

technical field [0001] The invention relates to the technical field of oxygen production equipment, in particular to an electric reversing control valve for oxygen production and a control method. Background technique [0002] Molecular sieve oxygen production refers to the separation and production of oxygen from air at room temperature by using the adsorption characteristics of molecular sieves. In this process, it is usually necessary to alternately send air to the adsorption tower and extract vacuum, which requires a control valve to realize the conversion operation. In the prior art, a plurality of two-way control valves are often used in combination, and PLC control programs are used to control the valve action. The structure is complex and the control is cumbersome. Contents of the invention [0003] The object of the present invention is to provide an electric reversing control valve for oxygen production, which not only can realize the reversing quickly and smooth...
