Detailed Description

The invention will be further described with reference to the following figures and examples: as shown in fig. 1 and 2, the electromagnetic switching valve for an oxygen generator is provided with an inseparable valve body 11, and integrates a plurality of electromagnetic valves required by the oxygen generator.

One end face of the valve body is provided with a fixed disc 13 which is used for being spliced with an oxygenerator adsorption tower cover in a sealing mode, a pair of two-position three-way valves are arranged in the valve body 11, and a pair of air inlet ports 1, a pair of breathing ports 2 and a pair of nitrogen discharge ports 3 of the pair of two-position three-way valves are all arranged on the fixed disc 13 and are used for being connected with a pair of air inlets, a pair of sieve barrel openings and a pair of nitrogen discharge ports of the oxygenerator adsorption tower cover in a sealing mode. Oxygenerator adsorption tower lid is the gas circuit control core of molecular sieve formula double tower oxygenerator, controls the oxygenerator admit air, arrange nitrogen and double tower and switch, and traditional oxygenerator adsorption tower lid gas circuit is complicated, and control is loaded down with trivial details, obtains simplifying the back at oxygenerator own gas circuit, can carry out integration transformation, improves production efficiency by a wide margin.

As shown in fig. 2, a pair of air inlet interfaces 1, a pair of breathing interfaces 2 and a pair of nitrogen discharging interfaces 3 are arranged in a centralized and compact manner, symmetrically arranged on the fixed disc 13 and butted with an air path interface of an adsorption tower cover of an oxygen generator. The fixing plate 13 has a transverse dimension exceeding the transverse width of the valve body so that fastening holes 12 for screw connection are symmetrically distributed in the fixing plate 13 around all ports. The fastening nails are symmetrically distributed, so that each interface can be hermetically connected and cannot leak gas under the high pressure of compressed gas.

Air inlet interface 1, breathing interface 2 and nitrogen discharging interface 3 all are equipped with sealed chimb 15, and sealed chimb 15 covers the interface butt joint with the adsorption tower of oxygenerator, a pair of two-position three-way valve passes through the sealed interval of division wall 10, and the inlet channel 4 of intercommunication passes through division wall 10 in a pair of air inlet interface 1 and keeps apart, and a pair of air inlet interface 1 is kept apart with the external world by the common sealed chimb 15 of round to and be connected with a pair of air inlet of oxygenerator adsorption tower lid by the common sealed chimb 15 of round.
