Embodiment 1

[0035] please combine Figure 1 to Figure 8 As shown, a sliding vane ventilator gas pressure flow control valve of the present invention includes a gas distribution cylinder, a gas distribution fixing piece, and a gas distribution sliding piece, wherein,

[0036] The gas distribution cylinder is a cylinder with a hollow cylindrical structure with one end open and the other end semi-open. The left and right ends of the gas distribution cylinder are respectively wound with several electromagnetic coils, including the left electromagnetic coil and the right electromagnetic coil. There is a blocking piece inside the gas distribution cylinder. The structure of the blocking piece just matches the shape of the opening at the left end of the air distribution cylinder;

[0037] The gas distribution fixing piece is a rectangular sheet structure, and the gas distribution fixing piece is provided with a left air distribution hole and a right air distribution hole;

[0038] The air distri...

Embodiment 2

[0052] See Figure 9 As shown, in this embodiment, the basic structure of the gas pressure and flow control valve of the sliding vane ventilator is the same as that of Embodiment 1, the difference is that the air distribution cylinder in this embodiment is a fully closed structure at both ends, and it is equipped with The side of the gas cylinder is provided with a breathing connecting pipe 1000, a high-pressure gas connecting pipe 2000 and an ambient atmosphere connecting pipe 3000. The shape of the gas distribution hole and the left and right gas distribution holes can be circular, oval, square, rhombus or other arbitrary shapes, and can be adjusted according to different The above-mentioned different structures and shapes can also achieve the technical effect as in the first embodiment. Since the specific implementation is the same as that in the first embodiment, details are not repeated here.

Abstract

The invention discloses a gas pressure flow control valve of a sliding-sheet type respirator, and a working principle of the gas pressure flow control valve. The left and right ends of a gas distribution cylinder are respectively provided with a plurality of solenoids in a winding manner. The interior of the gas distribution cylinder is provided with a blocking sheet. A gas-distribution fixed sheet is in a rectangular sheet structure. The center of a gas-distribution sliding sheet is provided with a gas distribution hole. The gas-distribution fixed sheet is fixed in the gas distribution cylinder, and cooperates with the blocking sheet, thereby enabling the interior of the gas distribution cylinder to be divided into a first gas chamber, a second gas chamber, and a third gas chamber. The gas-distribution sliding sheet can be slidingly installed with the gas-distribution fixed sheet, and the gas distribution hole on the gas-distribution sliding sheet achieves the sealing and opening of left and right gas distribution holes on the gas-distribution fixed sheet, so as to achieve that a control valve controls gas pressure flow. Through the interaction of solenoids with a magnet, the position of the gas-distribution sliding sheet is adjusted. The difference in coincidence areas between sliding sheet openings and the gas distribution holes determines the opening and closing degrees. The control valve can adjust the intensity of flow and pressure of air entering into a patient.

Description

technical field [0001] The invention relates to the technical field of a ventilator, in particular to a sliding vane ventilator gas pressure flow control valve and its working principle. Background technique [0002] With the improvement of living standards and the advancement of science and technology, ventilators have entered the homes of ordinary people from hospitals. Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity; its mechanism of action is to assist or control the patient's autonomous Respiratory exercise, in order to achieve gas exchange in the lungs, reduce the power consumption of human respiratory muscles, and facilitate the recovery of respiratory function, it can also be called a mechanical ventilator clinically. Clinically, ventilators are used to treat various diseases such as chronic o...
