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
The invention belongs to energy-saving field of pneumatic, relate to a kind of gas tank that can be used for multiple pressure gas circuit simultaneously.
Background technique
Gas tank is an element important in the pneumatic system, and its effect mainly is elimination pressure pulsation, stores a certain amount of pressurized air, can solve the contradiction of interior gas consumption of short time greater than the source of the gas air demand on the one hand; Can when interrupting, air feed keep the air feed of short time on the other hand, so that take measures to guarantee the safety of pneumatic equipment.So gas tank is widely used in pneumatic system and pneumatic equipment.
Popularization along with pneumatic power-saving technology, push air supply method and be widely used in current industrial field, because the existence of the gas circuit of different pressures, making needs the same equipment or a plurality of gas tanks of workshop needs of different pressures, so increase the space that equipment occupies, be unfavorable for the application of industry spot.At this situation, the multi-pressure shared type gas tank that the present invention proposes can be used for the gas circuit of multiple pressure simultaneously, greatly reduces the space that pneumatic equipment occupies, and this gas tank is flexible for installation, easy to use, simple in structure in addition, helps the popularization of industry spot.
Summary of the invention
The objective of the invention is: provide a kind of simple in structure, cost is low, flexible for installation, easy to use, the gas tank that can be used for multiple pressure gas circuit simultaneously.
Technological scheme of the present invention is:
1. the working principle of multi-pressure shared type gas tank
The gas tank stored-gas is supplied with by high-pressure air source, and is connected with variant pressure circuit by each pressure-supplementing valve.When each low tension loop pressure was lower than its setting pressure, gas tank from trend low tension loop tonifying Qi, and simultaneously for the high tension loop air feed, had reduced each low pressure gas circuit pressure pulsation by pressure-supplementing valve.
Advantage of the present invention is: simple in structure, cost is low, flexible for installation, easy to use, can avoid using a plurality of gas tanks to make, reduce device space occupancy volume, help the popularization at industrial energy saving scene.

Embodiment
Below the present invention is further illustrated.
Fig. 1 is the multi-pressure shared type gas tank structural drawing, gas tank among the figure (1) has a plurality of relief openings, in gas tank (1) series connection and the high-pressure gas circuit, be connected with pressure-supplementing valve (2) between gas tank (1) and the low pressure gas circuit, when the difference of gas tank exhaust port pressure and low tension loop pressure during less than a certain setting value, this pressure-supplementing valve (2) is closed fully, does not have air to flow through; The difference of gas tank (1) exhaust port pressure and low pressure gas circuit pressure is during greater than a certain setting value, and this pressure-supplementing valve (2) is opened, and transfers big valve opening automatically, the air supply low tension loop A/B in the gas tank.Thereby reduced low tension loop pressure pulsation.
2. the setting principle of pressure-supplementing valve pressure
Fig. 2 is the pressure-supplementing valve structural drawing, the pressure of rotation regulator bolts (1) setting spring A (2), spring A (2) promotes baffle plate (4) closes a mouth, one cavity pressure acts on the top of piston (5), promotion valve shaft (7) makes spool (8) move downward valve port and opens, and pressurized air just flows into second side from first side.The second side gas pressure is in the below of piston (5), and when a cavity pressure and two cavity pressures balance each other, this moment, the second side outlet pressure was a setting pressure.When second side pressure raises, act on the piston (5) differential pressure upwards, promote valve shaft (7) spool (8) valve port that moves upward reduced gradually, during more than or equal to setting pressure, spool (8) is closed fully until the pressure of second side.Rotation regulator bolts (1) can regulate pressure-supplementing valve setting pressure.
Claims (2)
1, gas tank of a kind of usefulness is the method for a plurality of different pressures loop ftercompction simultaneously, and it is characterized in that: the gas tank stored-gas is supplied with by high-pressure air source, and is connected with variant pressure circuit by each pressure-supplementing valve.When each low tension loop pressure was lower than its setting pressure, gas tank from trend low tension loop tonifying Qi, and simultaneously for the high tension loop air feed, had reduced each low pressure gas circuit pressure pulsation by pressure-supplementing valve.
2, realize right 1 described a kind of pressure-supplementing valve, it is characterized in that: when pressure-supplementing valve second side pressure was lower than setting value, this pressure-supplementing valve was opened valve port automatically, and high-pressure air flows into second side from first side; When second side pressure is equal to or higher than setting pressure, this pressure-supplementing valve self acting stop valve mouth.
