Abstract
The utility model discloses a large flow intelligent gas pressurization device belonging to the field of industrial gas pressurization technology. The utility model mainly relates to a pressurization device connected in parallel to the pressurization mechanism to realize the large flow pressurization. The high pressure gas produced by the work of the pressurization mechanism group constituted by a plurality of groups of pressurization mechanisms can be input in a gas tank. A magnetic switch is disposed on the terminal point of the piston stroke of the pressurization mechanism. When the piston arrives the terminal point of the piston stroke, the magnetic switch outputs signals to a control device. The control device control the reversing process of a reversing valve, the piston moves in the opposite direction, thereby the impact between the piston and a cylinder can be prevented, and the vibration of the mechanism can be reduced. The pressurization mechanisms can be divided into two groups with the same amount, and can be installed in opposite directions according to the direction of the piston. When the piston moves in opposite directions, the vibration caused by the inertia force can be reduced. The pressurization mechanism group of the pressurization device can be expanded. When the flow is small, the single pressurization mechanism can be connected in parallel to a pneumatic loop expansion port in order to increase the flow. When the flow is large, the single pressurization mechanism can be unloaded to reduce the flow.
Description
Technical field
The invention belongs to energy-saving field of pneumatic, relate to a kind of big flow quantity intelligent gas pressurized device.
Background technique
Gas pressurized device is the key technology of energy-saving field of pneumatic.In pneumatic system, some occasion often needs a small amount of, partial high pressure gas.For example: indivedual or partial devices need be used high pressure in the gas circuit; Because remote gas transmission or gas leakage cause main gas circuit pressure to descend, and can not guarantee the minimum working pressure of Pneumatic actuator; The space is narrow, can not dispose the heavy caliber cylinder, but ouput force must guarantee again, or the like.Solve this type of problem, what adopt usually at present is local supercharge method, and it is to utilize supercharging device to obtain pressurized gas, can save cost, reduce bleed pressure, especially pneumatic system is carried out reducing energy consumption, and its effect is more outstanding.But also there is deficiency in pressure charging valve, and is little such as flow, and especially for pressure ratio when high, this shortcoming is more outstanding.
The present invention is according to the fluctuation of gas pressure in the gas tank, and controller is controlled many booster bodies and worked simultaneously, has characteristics such as output flow is big, vibration is little, noise is low, delivery pressure is adjustable, has the excellent popularization prospect.
The model utility content
The objective of the invention is: a kind of big flow, simple in structure, vibration is little, automaticity is high gas pressurized device exported is provided.
Technological scheme of the present invention is:
1. the booster body group is composed in parallel by a plurality of booster bodies, and all booster bodies are divided into two groups of same number, by piston direction, and reverse the connection;
2. booster body group magnetic switch is installed on the piston stroke terminal point of each booster body, and when piston walked to the stroke end, magnetic switch outputed signal to controller; The switching-over of controller control selector valve; The piston reverses direction motion, when gas pressure in the gas tank surpassed the upper pressure limit of setting, the pressure switch that is installed on the gas tank was exported signal to controller; Controller control selector valve stops switching-over, and the booster body group stops to export pressurized gas; When the gas tank internal pressure was lower than the low pressure limit of setting, pressure switch stopped to export signal, the switching-over of controller control selector valve, and the booster body group continues the output pressurized gas;
3. supercharging device is provided with the spare extension interface, and when the bigger flow of needs, parallel connection inserts booster body.
Description of drawings
Fig. 1 is the structure diagram of high-efficiency and energy-saving gas booster of the present invention.
1---solenoid directional control valve; 2---left magnetic switch; 3---right magnetic switch; 4---one-way valve A; 5---one-way valve B; 6---one-way valve C; 7---one-way valve D; 8---pressure switch; 9---gas tank; 10---controller; 11---booster cavity A; 12---actuator chamber A; 13---actuator chamber B; 14---booster cavity B.
Embodiment:
1. when the pressure of gas in the gas tank (9) was higher than capping, pressure switch (8) outputed signal to controller (10), and controller (10) control solenoid directional control valve (1) stops switching-over, and the booster body group stops to export pressurized gas; The pressure of gas is lower than setting down in limited time in gas tank (9); Pressure switch (8) stops to send signal; Controller (10) control solenoid directional control valve (1) switching-over, booster body group continue the output pressurized gas, thereby realize that the interior gas pressure of gas tank (9) remains in the pressure setting range.
2. first booster body mode of execution described, other booster body mode of execution is identical therewith.Part low-pressure gas can directly get into booster cavity A (11) and booster cavity B (14); Another part low-pressure gas can get into actuator chamber A (12), actuator chamber B (13) through solenoid directional control valve (1); When solenoid directional control valve (1) is put when upper; To atmosphere, low-pressure gas charges into booster cavity A (11), actuator chamber B (13) to the interior gas of actuator chamber A (12) through solenoid directional control valve (1) row, and piston carries out supercharging toward right motion to the gas in the booster cavity B (14); When the pressure of B in the booster cavity (14) gas greater than gas tank (9) in the pressure of gas, the gas in the booster cavity B (14) charges into gas tank through one-way valve D (7).When piston walks to right lateral journey terminal point; Right magnetic switch (3) outputs signal to controller (10), controller (10) control solenoid directional control valve (1) switching-over, and the gas row in the actuator chamber B (13) is to atmosphere; Low-pressure gas charges into actuator chamber A (12), booster cavity B (14); To the gas boosting in the booster cavity A (11), when the pressure of gas in the booster cavity A (11) is higher than the gas pressure in the gas tank (9), the interior gas of booster cavity A (11) charges into gas tank (9) through one-way valve B (5) to piston to left movement.When piston walks to left lateral journey terminal point; Left side magnetic switch (2) outputs signal to controller (10), controller (10) control solenoid directional control valve (1) switching-over, and the interior gas row of actuator chamber A (12) is to atmosphere; Low-pressure gas charges into booster cavity A (11), actuator chamber B (13); Piston moves right, thereby goes round and begins again, and booster body is exported pressurized gas constantly.
Advantage of the present invention is: output flow of the present invention is big, simple in structure, vibration is little, automaticity is high, helps the on-the-spot popularization of industrial energy saving.
