Description

Technical Field

[0001] This application relates to the technical field of special gas transportation, and more particularly, to a forced gas supply system. Background Art

[0002] In the prior art, there are usually two gas supply methods between a special gas supply device (such as a gas cylinder) and a gas-using device. One is the electric gas supply method. Generally, a solenoid valve, a shuttle valve, and a pneumatic valve are sequentially connected between the gas cylinder and the gas-using device. Specifically, the solenoid valve is automatically controlled by a controller (PLC) and can drive the opening and closing of the pneumatic valve via the shuttle valve to supply gas to the gas-using device. The other is the manual gas supply method (also known as forced gas supply). Generally, a manual valve is added between the gas cylinder and the shuttle valve corresponding to the solenoid valve (that is, the manual valve and the solenoid valve are distributed in parallel) so that when the electric gas supply method fails, forced gas supply can be performed by operating the manual valve.

[0003] However, since the gas storage capacity of a single gas cylinder is limited, after the gas storage is exhausted, the gas cylinder usually needs to be replaced. In order to ensure the normal operation of the gas-using device during the gas cylinder replacement process, usually two gas cylinders are set to supply gas to one electrical device, and two parallel electric gas supply pipelines and two parallel manual gas supply pipelines are set at the same time so that both gas supply methods have alternative routes. Specifically, for the two parallel electric gas supply pipelines, generally, an electric gas supply pipeline is set between each gas cylinder and the gas-using device; for the two parallel manual gas supply pipelines, generally, the two gas cylinders are connected to the same gas supply main pipe and then connected to two parallel gas supply branch pipes through adapters. Each gas supply branch pipe is controlled by a manual valve and is connected to the corresponding shuttle valve. Among them, since most of the functional devices in the two gas supply methods are concentratedly installed on the panel, and in addition, the corresponding pipelines need to be laid out, it has become a major problem currently faced on how to reasonably arrange a large number of functional devices on the panel. Summary of the Utility Model

[0004] The purpose of this application is to provide a forced gas supply system, which can effectively solve the problem of how to reasonably arrange a large number of functional devices on the panel.

[0005] The embodiments of this application are implemented as follows:

[0006] An embodiment of the present application provides a forced air supply system, which includes two air sources, a faceplate, a manual air supply unit, and two electric air supply units. The manual air supply unit includes a main air supply pipe and two air supply branch pipes. One end of the main air supply pipe is connected to the two air sources, and the other end is respectively connected to one end of the two air supply branch pipes through a three-way valve. Each air supply branch pipe is provided with a manual valve, and the manual valves are fixed on the faceplate. The two manual valves are adjacent and arranged side by side along a first preset direction. One end of each air supply branch pipe far from the three-way valve is respectively connected to the corresponding shuttle valve; each electric air supply unit is connected between the corresponding air source and the shuttle valve.

One end of the main air supply pipe is connected to the two air sources, and the other end is respectively connected to one end of the two air supply branch pipes through a three-way valve. Each air supply branch pipe is provided with a manual valve, and one end of each air supply branch pipe far from the three-way valve is respectively connected to the corresponding shuttle valve, that is, there are two manually distributed parallel air supply pipelines. Among them, the two manual valves are adjacent and arranged side by side along a first preset direction.

[0008] In some alternative embodiments, the three-way valve is a T-shaped three-way valve.

At the same time, it can also improve the fluidity of the gas during transportation; in addition, in the first preset direction, the other air outlet of the T-shaped three-way valve is also set to face one side of the other manual valve, and this setting can make the bending degree of the air supply branch pipe between the T-shaped three-way valve and the manual valve smaller, thus facilitating the installation of this section of pipeline.

[0013] In the above technical solution, the two air inlets of the shuttle valve are respectively arranged at both ends in the second preset direction, which facilitates a shuttle valve to communicate with its corresponding solenoid valve and manual valve at the same time (the air outlet directions of the solenoid valve and the manual valve are usually set in opposite directions).

[0014] In some alternative embodiments, in each air supply branch pipe, the manual valve is communicated with a plurality of shuttle valves through a first adapter.

[0015] In the above technical solution, a plurality of shuttle valves are arranged in each air supply branch pipe, so as to control multiple gas-using devices by one manual valve at the same time. Compared with each shuttle valve being correspondingly provided with a manual valve, the workload can be reduced, and at the same time, the structure of the faceplate can be simplified.

[0016] In some alternative embodiments, in the first preset direction, a plurality of shuttle valves are arranged side by side at intervals.

[0020] In some alternative embodiments, a second adapter is further arranged in each air supply branch pipe. The second adapter is located between the manual valve and the first adapter. The air inlet of the second adapter is communicated with the air outlet of the manual valve. The first air outlet of the second adapter is communicated with the air inlet of the first adapter, and the second air outlet of the second adapter is communicated with a pneumatic display.

[0022] In some alternative embodiments, the second air outlet of the second adapter is connected to an auxiliary pipeline, the auxiliary pipeline is connected to the pneumatic display through a third adapter, and the third adapter is also connected to a pneumatic-electric converter.

[0023] In the above technical solution, the second air outlet of the second adapter is connected to an auxiliary pipeline, and an air-electric converter is additionally provided through the third adapter, which can give an alarm when an abnormal situation occurs in the gas transmission at the manual valve, thereby improving the air supply safety.

[0036] The following specifically describes a forced air supply system of the present application.

[0037] Refer to Figure 1 and Figure 2 and, an embodiment of the present application provides a forced air supply system 10, including two air sources 100, a faceplate 200, a manual air supply unit 300, and two electric air supply units 500. The manual air supply unit 300 includes an air supply main pipe 310 and two air supply branch pipes 330. One end of the air supply main pipe 310 is connected to the two air sources 100, and the other end is respectively connected to one end of the two air supply branch pipes 330 through a three-way valve 320. Each air supply branch pipe 330 is provided with a manual valve 331, and the manual valve 331 is fixed on the faceplate 200. The two manual valves 331 are adjacent and arranged side by side along a first preset direction a. One end of each air supply branch pipe 330 far from the three-way valve 320 is respectively connected to a corresponding shuttle valve 400; each electric air supply unit 500 is connected between the corresponding air source 100 and the shuttle valve 400.

[0038] It should be noted that the air outlet of the shuttle valve 400 is used to be connected to a pneumatic valve, and the pneumatic valve is used to be connected to the air inlet of the air supply device; the electric air supply unit 500 generally refers to a solenoid valve and its corresponding controller.

[0039] In the present application, the forced air supply system 10 includes two air sources 100, a faceplate 200, a manual air supply unit 300, and two electric air supply units 500. Specifically, there are two electric air supply units 500, and each electric air supply unit 500 is connected between the corresponding air source 100 and the shuttle valve 400, that is, there are two automatically parallel distributed air supply pipelines; the manual air supply unit 300 includes an air supply main pipe 310 and two air supply branch pipes 330. One end of the air supply main pipe 310 is connected to the two air sources 100, and the other end is respectively connected to one end of the two air supply branch pipes 330 through a three-way valve 320. Each air supply branch pipe 330 is provided with a manual valve 331, and one end of each air supply branch pipe 330 far from the three-way valve 320 is respectively connected to a corresponding shuttle valve 400, that is, there are two manually parallel distributed air supply pipelines. Among them, the two manual valves 331 are adjacent and arranged side by side along the first preset direction a. Compared with the installation form where the two are far apart and there are other functional devices between them, the installation form provided by the embodiment of the present application makes the two close enough and the arrangement is relatively regular, so as to facilitate connecting the two to the three-way valve 320 at the same time, having the advantage of a relatively reasonable layout.

[0040] It should be noted that the specific form of the three-way valve 320 is not limited and can be set according to the conventional selection in the art.

[0041] Refer to Figure 2, as an example, the three-way valve 320 is a T-shaped three-way valve 320. The axis line of the air outlet of the T-shaped three-way valve 320 in the second preset direction b is the same as the axis line of the air inlet of one of the manual valves 331; and in the first preset direction a, the other air outlet of the T-shaped three-way valve 320 faces one side of the other manual valve 331, and the second preset direction b is perpendicular to the first preset direction a.

[0042] In this embodiment, the three-way valve 320 adopts a T-shaped three-way valve 320 and sets the axis line of the air outlet of the T-shaped three-way valve 320 in the second preset direction b to be the same as the axis line of the air inlet of one of the manual valves 331, so that the air supply branch pipe 330 between the T-shaped three-way valve 320 and this manual valve 331 is straight, thus facilitating the installation of this section of pipeline. At the same time, it can also improve the fluidity of the gas during transportation; in addition, in the first preset direction a, the other air outlet of the T-shaped three-way valve 320 is also set to face one side of the other manual valve 331, and this setting can make the bending degree of the air supply branch pipe 330 between the T-shaped three-way valve 320 and this manual valve 331 smaller, thus facilitating the installation of this section of pipeline.

[0043] Refer to Figure 2 , as an example, in the first preset direction a, the two manual valves 331 are symmetrically distributed on the face plate 200.

[0044] In this embodiment, the two manual valves 331 are symmetrically distributed on the face plate 200 so that the overall structure of the face plate 200 is more regular.

[0045] In other possible embodiments, the two manual valves 331 can also be set in an asymmetric distribution form.

[0046] Refer to Figure 2 , as an example, in the second preset direction b, the first air inlet and the second air inlet of the shuttle valve 400 are respectively located at both ends of the shuttle valve 400. The first air inlet of the shuttle valve 400 is used to communicate with the solenoid valve, and the second air inlet of the shuttle valve 400 is communicated with the air outlet of the manual valve 331.

[0047] In this embodiment, the two air inlets of the shuttle valve 400 are respectively arranged at both ends in the second preset direction b, which is convenient for a shuttle valve 400 to communicate with its corresponding solenoid valve and manual valve 331 at the same time (the air outlet directions of the solenoid valve and the manual valve 331 are usually set in opposite directions).

[0048] Refer to Figure 2 and Figure 3 , as an example, in each air supply branch pipe 330, the manual valve 331 is communicated with a plurality of shuttle valves 400 through a first adapter 332.

[0049] In this embodiment, a plurality of shuttle valves 400 are provided in each gas supply branch pipe 330 so that a plurality of gas-consuming equipment can be controlled simultaneously through a manual valve 331. Compared with providing a manual valve 331 corresponding to each shuttle valve 400, this can reduce the workload and simplify the structure of the panel 200.

[0050] It should be noted that when a plurality of shuttle valves 400 are provided in each gas supply branch pipe 330 , a plurality of electric gas supply units 500 are also provided accordingly, that is, in a one-to-one correspondence.

[0051] It should be noted that the specific number of the shuttle valves 400 is not limited and can be adjusted according to actual needs, for example, there can be three.

[0052] In other possible implementations, only one shuttle valve 400 may be provided in each gas supply branch pipe 330 , that is, one manual valve 331 controls one shuttle valve 400 .

[0053] See also Figure 2 As an example, in the first preset direction a, a plurality of shuttle valves 400 are spaced apart and arranged side by side.

[0054] In this embodiment, the plurality of shuttle valves 400 are spaced apart and arranged side by side along the first preset direction a, so that the overall structure of the panel 200 is more regular.

[0055] See also Figure 2 As an example, in the first preset direction a, multiple shuttle valves 400 are located on the side of the corresponding manual valve 331 away from another manual valve 331, and the multiple shuttle valves 400 in the two air supply pipelines are symmetrically distributed on the panel 200.

[0056] In this embodiment, the plurality of shuttle valves 400 in the two gas supply pipelines are symmetrically distributed on the panel 200, so that the panel 200 has the advantage of a more regular overall structure and is also convenient for pipeline installation.

[0057] See also Figure 2 As an example, in the second preset direction b, the axis centerline of the air outlet of the manual valve 331 is the same as the axis centerline of the air inlet of the first adapter 332.

[0058] In this embodiment, in the second preset direction b, the axis line of the air outlet of the manual valve 331 is set to be the same as the axis line of the air inlet of the first adapter 332, so that the gas supply branch pipe 330 between the manual valve 331 and the first adapter 332 is a straight line, thereby facilitating the installation of this section of the pipeline and, at the same time, improving the fluency of the gas during the transportation process.

[0059] See also Figure 2 and Figure 3, as an example, a second adapter 333 is further provided in each air supply branch pipe 330. The second adapter 333 is located between the manual valve 331 and the first adapter 332. The air inlet of the second adapter 333 is communicated with the air outlet of the manual valve 331. The first air outlet of the second adapter 333 is communicated with the air inlet of the first adapter 332, and the second air outlet of the second adapter 333 is communicated with a pneumatic display 350.

[0060] In this embodiment, in each air supply branch pipe 330, a second adapter 333 is added between the manual valve 331 and the first adapter 332, and a pneumatic display 350 is communicated with the second air outlet of the second adapter 333, which can display the gas transmission condition at the manual valve 331 in real time, making the gas on-off at the manual valve 331 visible.

[0061] Refer to Figure 2 and Figure 3 , as an example, the second air outlet of the second adapter 333 is communicated with an auxiliary pipeline 340. The auxiliary pipeline 340 is communicated with the pneumatic display 350 through a third adapter (not shown in the figure), and a pneumatic-electric converter 360 is also communicated with the third adapter.

[0062] In this embodiment, the second air outlet of the second adapter 333 is communicated with the auxiliary pipeline 340, and a pneumatic-electric converter 360 is added through the third adapter in the auxiliary pipeline 340, which can give an alarm when an abnormal situation occurs in the gas transmission at the manual valve 331, thereby improving the air supply safety.

[0063] Refer to Figure 2 , as an example, in the second preset direction b, the axis lines of the air inlets of the first adapter 332 and the second adapter 333 are the same.

[0064] In this embodiment, in the second preset direction b, the axis lines of the air inlets of the first adapter 332 and the second adapter 333 are the same, that is, they are basically on the same straight line, which has the advantage of relatively neat arrangement.
