Problems solved by technology

[0003] With the promotion of pneumatic energy-saving technology, the press air supply method is widely used in today's industrial fields. Due to the existence of air circuits with different pressures, the same equipment or workshop that requires different pressures requires multiple air tanks, which increases the space occupied by the equipment. , not conducive to the application of industrial field

Embodiment Construction

[0014] The present invention will be further described below.

[0015] figure 1 It is a structural diagram of a multi-pressure shared gas tank. In the figure, the gas tank (1) has multiple exhaust ports. The gas tank (1) is connected in series with the high-pressure gas circuit. Valve (2) is connected, when the difference between the pressure at the exhaust port of the gas tank and the pressure of the low-pressure circuit is less than a certain set value, the supplementary pressure valve (2) is completely closed, and no air flows through; the exhaust port of the gas tank (1) When the difference between the pressure and the pressure of the low-pressure air circuit is greater than a certain set value, the pressure supplement valve (2) is opened, and the opening of the valve is automatically enlarged, and the air in the gas tank is supplied to the low-pressure circuit A / B. Thereby reducing the pressure pulsation of the low pressure circuit.

Abstract

The invention belongs to the field of pneumatic system energy conservation and achieves a gas tank which can be applied to various pressure gas paths at the same time. The content of the invention mainly relates to a method for supplementing pressure for various different pressure loops at the same time by using one gas tank. The multi-pressure air path shared type gas tank is different from the conventional gas tank, the storage gas in the gas tank and is supplied by a high-pressure gas source and is connected with different pressure loops through each pressure supplementing valve. When the pressure of each low-pressure loop is lower than the set pressure, the gas tank automatically supplements gas to the low-pressure loops through the pressure supplementing valve, and supplements gas to the high-pressure loop at the same time so that the pressure pulsation of each low-pressure loop is reduced. The gas tank has the advantages of simple structure, low cost, flexible mounting and convenient use, and is advantageous for wide application in the field of pneumatic energy conservation.

Description

[0001] The invention belongs to the field of energy saving of pneumatic systems, and relates to an air tank which can be used in multiple pressure air circuits at the same time. Background technique [0002] The air tank is an important component in the pneumatic system. Its function is mainly to eliminate pressure pulsation and store a certain amount of compressed air. On the one hand, it can solve the contradiction that the air consumption is greater than the air supply in a short period of time; In the event of interruption, maintain a short-term air supply in order to take measures to ensure the safety of pneumatic equipment. Therefore, air tanks are widely used in pneumatic systems and pneumatic equipment. [0003] With the promotion of pneumatic energy-saving technology, the press air supply method is widely used in today's industrial fields. Due to the existence of air circuits with different pressures, the same equipment or workshop that requires different pressures re...
