[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] The double pressure valve is a component with two input ports and one output port. In the working of the double pressure valve, the two input ports (usually marked as A and B) can access different pressure gases, and the output port (usually marked as C) will output the gas according to the gas pressure of the input port and the setting of the valve. The following is the output situation under different conditions:

[0023] 1, the pressure of input ports A and B is the same

[0024] If the gas pressure of the two input ports is the same, the pressure of the output port will also be basically equal to the pressure of the input port. In this case, the double pressure valve is in a balanced state, and the pressure of the output gas will not change significantly.

[0025] 2, the pressure of input port A is higher than that of input port B

[0026] If the design of the double pressure valve is to prefer the high pressure source (for example, when the valve is designed to open at the high pressure input port A), then the output port C will output the pressure close to that of the input port A;

[0027] If the valve control logic is set to prefer to use low pressure gas, the output port may be reduced to the pressure of input port B.

[0028] 3, the pressure of input port B is higher than that of input port A

[0029] If the double pressure valve prefers the high pressure source, then the output port C will output the pressure close to that of the input port B;

[0030] If the valve is designed to prefer low pressure gas, the output port may output the pressure close to that of the input port A.

[0031] The following embodiment of the article illustrates the design of a dual-pressure valve that prioritizes a high-pressure source. That is, when the pressure at input port A is higher than that at input port B, output port C will output a pressure close to that at input port A.

[0032] Example 1:

[0033] like Figure 1 As shown, a pipeline system includes a dual-pressure valve 1 and a connecting pipe 2, both ends of which are respectively connected to the two inlet ports of the dual-pressure valve 1. A pressure supply pipe 3 is connected to the connecting pipe 2, which splits the connecting pipe 2 into a first pipe 201 and a second pipe 202. When a medium (gas or oil) is supplied to the pressure supply pipe 3, the medium flows to the two inlet ports of the dual-pressure valve 1 through the first pipe 201 and the second pipe 202 respectively. Furthermore, a pressure-requiring element 4 is provided on the second pipe 202. The medium in the second pipe 202 can be diverted to the pressure-requiring element 4 for its operation. With the pressure-requiring element 4, the medium in the first pipe 201 and the second pipe 202 are at different pressures, thereby achieving different pressures of the medium supplied to the two inlet ports of the dual-pressure valve 1. The outlet port of the dual-pressure valve 1 is then opened to output the medium from the first pipe 201.

[0034] Taking gas as the medium, in the above system, an air compressor delivers gas at a certain pressure (e.g., 0.5 MPa) to the pressure supply line 3. At this time, the gas in the first line 201 is supplied to one inlet of the dual-pressure valve 1, and the gas in the second line 202 is supplied in a split manner to the other inlet of the dual-pressure valve 1 and the pressurized component 4. During this process, the pressurized component 4 will operate first. Then, the output of the dual-pressure valve 1 will deliver gas with a pressure close to that in the first line 201. This gas can be used for other pressurized components (cylinders, etc.) to enable their subsequent operation. Through the above design, this invention can achieve sequential activation of corresponding pipelines without the aid of a PLC or other controller, resulting in good performance and a low failure rate.

[0035] It should be noted that the pressure-requiring component 4 in this embodiment can be any pressure-requiring component in the prior art, and its type and specifications are not limited in this document.

[0036] Example 2:

[0037] The difference between the embodiment and the embodiment one is that the embodiment applies the pressing part 4 concretely, specifically, the pressing part 4 comprises the air control valve 401 and the first air cylinder 402, the air control valve 401 is connected to the second pipeline 202 through an input port and an output port, and the two interfaces of the first air cylinder 402 are communicated with the second pipeline 202 and the other output port of the air control valve 401. In normal use, the gas discharged through the pressure supply pipeline 3 is sequentially delivered to the second pipeline 202 and the air control valve 401, the second pipeline 202 connected with the air control valve 401 will shunt the gas to the input port of the double pressure valve 1 and the interface of the first air cylinder 402, and then the gas in the interface of the first air cylinder 402 can drive the piston rod to extend correspondingly, for example, the first air cylinder 402 can be regarded as a positioning air cylinder, and the action of the positioning air cylinder can position the product; then the output port of the double pressure valve 1 is opened, and the working pipeline 5 is connected to the output port, and a plurality of working parts 6 are arranged on the working pipeline 5, and the working part 6 can be a third air cylinder, and then the third air cylinder can be regarded as a clamping air cylinder, and the action of the clamping air cylinder can clamp the product.

[0038] Further, the embodiment can further comprise the foot valve 403 and the first electromagnetic valve 404 connected to the second pipeline 202 and used for controlling the air control valve 401, and the foot valve 403 and the first electromagnetic valve 404 can facilitate the staff to control the air control valve 401 better. It should be noted that the air control valve 401 can also be replaced equivalently according to the actual application scene, and the electrical connection between the foot valve 403, the first electromagnetic valve 404 and the air control valve 401 is a conventional technical means, and the details are not described herein to avoid complicated writing.

[0039] Embodiment three:

[0040] On the basis of the embodiment two, the pressing part 4 further comprises the second electromagnetic valve 405 and a plurality of second air cylinders 406, the second electromagnetic valve 405 is connected to the second pipeline 202 and used for controlling the action of the plurality of second air cylinders 406. It should be noted that the connection between the second electromagnetic valve 405 and the second air cylinder 406 is a conventional technical means, and the details are not described herein to avoid complicated writing.

[0041] The above describes one embodiment of the utility model in detail, but the content described can only be the preferred embodiment of the utility model, and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement within the application range of the utility model should still belong to the patent coverage range of the utility model.
