Problems solved by technology

[0002] At present, the volumetric compressor equipment with air valve is widely used. As the wearing part of the compressor, the air valve has higher requirements on the air valve in some high-speed and high-pressure applications, especially in aerospace, aviation, and navigation. It is used on mobile equipment such as vehicles and vehicles, which requires not only small size and light weight, but also high efficiency and reliability; by increasing the operating speed, the volume and weight can be reduced, but its efficiency and reliability are reduced, which requires the improvement of these equipment. The valve structure makes it develop towards a small and compact structure; therefore, the improvement of the air valve is very necessary

Embodiment 1

[0018] Implementation example 1, see figure 1 , the valve plate 1, the spring inclined sleeve 2, the spring 3, the inclined column 4 and the valve lift limiter 5 are arranged in sequence. The included angle between the inclined column 3 and the vertical direction is 0°~90°; the spring inclined sleeve 2 and the inclined column 4 should ensure the same angle. The spring 3 is arranged on the inclined column 4 between the spring slanted sleeve 2 and the valve lift limiter 5 ; the valve lift limiter 5 is fixed on the inclined column 4 . The movement of the valve plate 1 is constrained by the inclined guide rail 4, so that the valve plate is opened and closed along the inclined guide rail when subjected to gas force and spring force. The valve plate moves along the inclined column 4, and the inclination angle of the guide hole corresponding to the inclined column 4 on the valve plate should be consistent with the inclination angle of the inclined column. The thickness and quality o...

Embodiment 2

[0023] Implementation example 2, see figure 2 , the valve plate 6, the valve stand 7, the spring 8, the cover plate 9 and the bolt 10 are arranged in sequence. The two ends of the valve plate 6 are placed in the left and right valve frames 7, and the guide rails in the valve frame 7 replace the inclined columns, which restrict the movement of the valve plate; the angle between the guide rails in the valve frame 7 and the vertical direction It is 0°~90°, which restricts the movement direction of the valve plate; the spring 8 is arranged in the spring hole of the valve table frame 7; the inclination angle of the spring hole is consistent with the inclination angle of the guide rail. The cover plate 9 is arranged on the upper surface of the valve frame 7 for compressing the spring and fixing the valve frame, and the bolts 8 are arranged in the bolt holes of the valve frame 7 . The guide rail of 7 in the valve bench constrains the movement direction of the valve plate, and the i...

Abstract

The invention discloses a plate valve for a reciprocating compressor. The plate valve comprises spring inclined sleeves, springs, inclined columns and valve piece lift limiters which are arranged sequentially. The included angle of the inclined columns and the vertical direction is 0 degree-90 degrees. When the pressure in an air cylinder is smaller than the pressure of an exhaust cavity, a valve piece is static, and at this moment, the springs press the valve piece on a valve plate to achieve a sealing function. When pressure in the air cylinder is larger than the pressure of the exhaust cavity, the valve piece moves along the inclined columns under the action of gas force and spring force. According to the plate valve, by means of inclining motion of the valve piece, when the valve piece is opened, an exhaust opening is opened directly, so that the through flow area of an air valve is increased, and exhaust resistance loss and exhaust noise of the compressor are reduced. Meanwhile, the stress state of the air valve is improved, abrasion is reduced, and the life of the valve piece is prolonged.
