Abstract
Description
Technical Field
[0001] This invention provides an integrated electromagnetic valve for an external counterpulsation gas tank, belonging to the technical field of gas supply and transmission devices. Background Technology
[0002] External counterpulsation (EECP) is a non-invasive treatment that uses external devices to improve blood supply to the heart. It is mainly used for patients with coronary heart disease, angina pectoris, and chronic heart failure. Its principle is to use an inflatable balloon to compress the lower limbs and buttocks during diastole, increasing blood return and cardiac blood supply, thereby improving myocardial ischemia and systemic circulation.
[0003] Currently, the gas supply and delivery system of the existing external counterpulsation system is set up independently. Due to the excessive length and bends in the pipeline, the resistance along the gas delivery path is increased, and there is a phenomenon of gas leakage during the gas delivery process.
[0004] Based on this, the present invention provides an integrated solenoid valve for an external counterpulsation gas tank. Summary of the Invention
[0005] The technical problem solved by this invention is that the external counterpulsation gas supply system is set up independently, and the excessively long and curved pipeline increases the friction resistance during gas delivery, resulting in gas leakage during the gas delivery process.
[0006] To solve the technical problem, the technical solution provided by the present invention is: an integrated external counterpulsation gas tank and solenoid valve, including a gas tank, the gas tank is provided with 3 DN15 internal thread interfaces, the 3 DN15 internal thread interfaces are provided with interconnected solenoid valves, the gas tank (1) is provided with a DN15 short pipe (4) connected to the air compressor interface, with a length of 50mm, and the bottom of the gas tank is provided with a mounting base.
[0007] Furthermore, the gas storage tank is provided with an air hole that communicates with a DN15 internal thread interface. The DN15 internal thread interface is seamlessly welded to the outer wall of the gas storage tank and communicates with the air hole. The diameter of the air hole is 20mm, and the specification size of the DN15 internal thread interface is DN15.
[0008] Furthermore, the gas storage tank has a height of 400-600mm and a length of 600mm, and is installed horizontally; the gas storage tank has a diameter of 300-400mm and a height of 400mm, and is installed vertically.
[0009] Furthermore, the gas storage tank is installed horizontally, with the three DN15 internal thread interfaces arranged in a straight line; the gas storage tank is installed vertically, with the three DN15 internal thread interfaces arranged in a triangular pattern.
[0010] Furthermore, the mounting base is provided with mounting holes.
[0011] The beneficial effects of this invention are as follows: This invention involves opening a hole and welding a DN15 internal threaded pipe fitting on the gas storage tank, and directly installing the solenoid valve on the gas storage tank. Based on the original separate design of the gas storage tank and solenoid valve, this invention can design an integrated design of the gas storage tank and solenoid valve, eliminating the traditional connecting pipe between the solenoid valve and the gas storage tank. This solves the problems of excessively long pipelines causing gas leakage and increased resistance along the gas delivery path, and eliminates gas leakage between gas delivery pipelines.

[0018] The invention will be further described below with reference to the accompanying drawings.
[0019] According to the appendix Figure 1-4 As shown: This invention provides an integrated solenoid valve for an external counterpulsation gas tank, including a gas tank 1. The gas tank 1 has three DN15 internal thread interfaces 2, arranged in a straight line. A solenoid valve 3 is connected to each DN15 internal thread interface 2. The gas tank 1 has an air hole connected to the DN15 internal thread interface 2, with a diameter of 20mm. The DN15 internal thread interface 2 is DN15 in size and is seamlessly welded to the outer wall of the gas tank 1 and connected to the air hole. Specifically, a DN15 internal thread fitting is welded into the gas tank 1, and the solenoid valve 3 is directly installed on the gas tank, solving the problems of air leakage due to excessively long pipelines and increased resistance along the gas delivery path.
[0020] As an optional embodiment, the air tank 1 is provided with a DN15 short pipe 4 with a length of 50mm for connecting to the air compressor interface. The air compressor works to store compressed gas in the air tank 1. The air tank 1 has a height of 400-600mm and a length of 600mm. The air tank 1 is installed horizontally. The diameter of the air tank 1 is 300-400mm. The air tank 1 is installed vertically. The air tank 1 is installed horizontally with a height of 400mm, and the three DN15 internal thread interfaces 2 are arranged in a straight line. The air tank 1 is installed vertically, and the three DN15 internal thread interfaces 2 are arranged in a triangular pattern. By selecting an air tank 1 of a suitable size, the air compressor and the air tank 1 mounting base 5 can be assembled into one unit to save space.
[0021] The air compressor uses existing technology. An air compressor, or air compressor for short, is a device that converts mechanical energy into gas pressure energy. Its core function is to increase the pressure or transport gas by compressing gas. The air compressor works to store compressed gas in the air tank 1. The bottom of the air tank 1 is provided with a mounting base 5. The mounting base 5 is provided with mounting holes for mounting the air tank 1 in a suitable position or on a device by bolts.
[0022] Working principle:
[0023] The air compressor interface pipe 4 is connected to the output end of the air compressor to store compressed gas in the air tank 1. A DN15 internal thread fitting is welded into the air tank 1, and the solenoid valves 3 are directly installed on the air tank. These are the arm airbag inflation / deflation solenoid valve groups, thigh airbag inflation / deflation solenoid valve groups, and calf airbag inflation / deflation solenoid valve groups. This design allows for the integration of the air tank 1 and solenoid valve 3, eliminating the traditional connecting pipe between the solenoid valve 3 and the air tank 1. This solves the problems of excessive pipeline length leading to air leakage and increased resistance along the gas delivery path, prevents air leakage between gas delivery pipelines, and facilitates the inspection, maintenance, and replacement of the solenoid valves. Compared to the traditional method, it requires less installation space and reduces gas loss.
[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
