Compressed air regulating valve

Abstract

The compressed air regulating valve is provided with an initial air pressure air inlet K from a high-pressure air storage chamber; the high-pressure air enters an air outlet M leading to the preheating buffer air tank through an air pressure adjusting valve Q; the size of the air pressure regulating valve Q is controlled by driving a flat piston connecting rod G and a lifting regulating valve tongue J to move up and down along a grooved rail P through a piston E under constant regulating air pressure C from the preheating buffer air tank; the lifting size of the valve flap depends on the constant spring F; working gas in a spring cavity R is used for breathing through a piston breathing opening H; the air inlet K and the air outlet M are connected with the reinforcing rib O and the transverse flange I through a vertical flange L or P; and D is a piston sealing ring. According to the working process of the compressed air regulating valve, when compressed air enters the preheating buffer air tank through the inlet K and the inlet M, decompression air branched from the buffer air tank generates constant pressure on the piston and overcomes the constant spring to enable the valve flap to move downwards along the groove-shaped rail, the larger the initial air pressure is, the smaller the regulating valve is closed, and otherwise, the larger the regulating valve is closed. Therefore, the air pressure of the preheating buffer air tank is not changed, and the stable power generation of the generator can be ensured only by using the constant air pressure (as shown in the figure).

Description

[0001] Technical Field: This invention relates to a compressed air regulating valve, specifically a key component for compressed air energy storage systems. Previous regulating valves were not designed for compressed air energy storage systems and were unsuitable for high-pressure output and large-scale use. This invention addresses this problem.

[0002] Background: Currently, the commonly known energy storage methods include gravity energy storage, battery energy storage, water storage energy storage, hydrogen energy storage, etc. However, all of the above methods have different drawbacks and shortcomings to varying degrees. Therefore, in terms of investment, environmental protection, construction, durability, storage capacity, speed stability, safety, efficiency, full utilization of existing caves, and operation and maintenance, gravity compressed air energy storage is the best choice.

[0003] Therefore, the compressed air regulating valve aims to provide energy storage and speed stabilization for power generation equipment, especially wind power generation equipment, thereby improving power generation capacity, storage capacity, and power generation stability. It also stores energy during off-peak hours (low electricity consumption) to reduce waste, create a green and environmentally friendly environment, reduce smog, and reduce the spread of disease.

[0004] Summary of the invention: The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a method for releasing the originally large and unstable compressed gas uniformly and at a constant speed through the present technology, thereby driving the generator to generate electricity at a constant speed and with a delayed time.

[0005] The specific technical solution of this compressed air regulating valve is: there is an initial air pressure inlet K from the high-pressure air storage chamber; the high-pressure air enters the air outlet M leading to the preheating buffer gas tank through the air pressure regulating valve Q; and the size of the air pressure regulating valve is controlled by the constant regulating air pressure C from the preheating buffer gas tank through the piston E, which drives the flat piston connecting rod G and the lifting regulating valve tongue J to move up and down along the groove track P; and the lifting size of the valve tongue also depends on the constant spring F; the working gas in the spring chamber R is to breathe through the piston breathing port H; the air inlet K and the air outlet M and the reinforcing rib O and the horizontal flange I are all connected by the vertical flange L; D is the piston sealing ring.

[0006] The working process of this compressed air regulating valve is: when the compressed air enters the preheating buffer gas tank through the inlets K and M, the reduced pressure air branched out from the buffer gas tank generates a constant pressure on the piston, and overcomes the constant spring to make the valve tongue move downward along the groove track. The greater the initial air pressure, the smaller the regulating valve is closed, and vice versa, to ensure that the air pressure in the preheating buffer gas tank remains unchanged. Only with this constant air pressure can the generator generate electricity stably (as shown in the figures).

[0007] The beneficial effects of the present invention are: 1. No matter how the initial air pressure changes, the output air pressure remains unchanged within a certain controllable range. 2. The structure is more scientific and reasonable, more practical and novel.

The diagram includes an initial pressure inlet valve K; a pressure regulating valve Q; an outlet valve M; a pressure regulating inlet port C; a piston E; a spring F; a piston connecting rod G and a valve tongue J; a horizontal flange I; a vertical flange L and a reinforcing rib O; a breathing port H; a piston cavity R; and a groove P.

[0009] Specific implementation: The present invention is further described below with reference to the accompanying drawings.

[0010] As shown in the figure, the main problem with this compressed air regulating valve is that the initial high-pressure air needs to enter the buffer tank after passing through the air pressure regulating valve. The compressed air distributed by the buffer tank then acts on the piston and valve tongue, which in turn limits the initial air pressure. The higher the initial air pressure, the smaller the air pressure regulating valve, and vice versa. In this way, a constant output air pressure is achieved.
