Description

Technical Field

[0001] This utility model relates to the field of pneumatic component technology, and in particular to a multifunctional integrated valve. Background Technology

[0002] Valves are one of the most common components in the pneumatic field, mainly used to control fluids. Especially in the laser technology industry, valve components play a crucial role. In laser cutting equipment, valve components are used to control the cutting gas path. For example, a two-position two-way solenoid valve is used to control the on / off of cutting gases such as oxygen and nitrogen. These valve components are usually connected by pipelines. The conventional design is to preset the gas pressure at the gas inlet end of the gas path, and the valve component, such as a two-position two-way solenoid valve, controls the on / off state, and the gas is directly output to the gas outlet end. In this case, the two-position two-way solenoid valve acts as a switch to control the on / off state of the gas path. A single two-position two-way valve can only realize the on / off control of a single gas pressure path. If it is necessary to switch between different gas pressures (such as 0.8MPa nitrogen for cutting stainless steel and 0.3MPa oxygen for carbon steel), an independent gas path must be configured for each gas pressure. Under multiple gas pressure requirements, the number of gas paths increases with the types of gas pressures. For example, three gas pressures require three sets of independent gas paths. This not only leads to redundant and intertwined pipelines and a large space occupation, but also greatly increases the difficulty and complexity of operation during actual assembly. Therefore, it is necessary to improve this design. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a multi-functional integrated valve with a simple and reasonable structure and convenient operation. It has two gas supply channels, which users can choose as needed. When channel A is selected, the gas is output to the outlet after being pressure regulated by an electric proportional valve, and the gas pressure value can be dynamically adjusted. When channel B is selected, the gas goes directly to the outlet, simplifying the gas supply process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The inlet of the two-position two-way solenoid valve B is connected to the inlet B, and the outlet of the two-position two-way solenoid valve B is connected to the inlet of the one-way valve B. The outlet of the one-way valve B is connected to the outlet.

[0006] Furthermore, the valve body includes a first valve body and a second valve body, the first valve body and the second valve body are fixedly connected, the first valve body is provided with the air inlet A and the air inlet B, the second valve body is provided with the air outlet, the two-position two-way solenoid valve A, the electro-proportional valve and the two-position two-way solenoid valve B are all provided in the first valve body, and the one-way valve A and the one-way valve B are both provided in the second valve body.

[0007] Furthermore, the first valve body is also provided with an air inlet C and an air inlet D. The air inlet C is connected to the air outlet through the A-channel, and the air inlet D is connected to the air outlet through the B-channel.

[0008] Furthermore, a first plug is provided on the air inlet C, which is used to seal the air inlet C, and a second plug is provided on the air inlet D, which is used to seal the air inlet D.

[0009] Furthermore, the A-channel includes a first air path and a second air path. The first air path is disposed within a first valve body, and the second air path is disposed within a second valve body. The inlet end of the first air path is connected to an inlet A or an inlet C. The outlet end of the first air path is connected to the inlet end of the second air path via an electro-proportional valve. The outlet end of the second air path is connected to an outlet. The first air path is provided with the two-position two-way solenoid valve A, and the second air path is provided with the one-way valve A.

[0010] Furthermore, the first valve body is provided with an air outlet A, and the second valve body is provided with an air inlet A. The air outlet end of the first air passage is connected to the air outlet A, and the air inlet end of the second air passage is connected to the air inlet A.

[0011] Furthermore, the air outlet A is connected to the electro-proportional valve via a first air passage connection block, and the electro-proportional valve is connected to the air inlet A via a second air passage connection block.

[0012] Furthermore, the B-channel includes a third air path and a fourth air path.

[0014] Furthermore, the air outlet B and the air inlet B are connected by a third air passage connecting block.

[0015] The beneficial effects of this utility model are as follows: The multi-functional integrated valve of this utility model has two internal air supply channels, which users can flexibly choose according to actual needs. These two air supply channels are channel A and channel B, and each channel can be controlled independently. When the user selects channel A for air supply, the compressed gas passes through an electro-proportional valve, which regulates the pressure before flowing out to the outlet. This allows for precise and stepless adjustment of gas pressure (or flow rate), rather than simple on / off control. In actual operation, the user can adjust the air pressure as needed through the electro-proportional valve to achieve dynamic adjustment of the air pressure value. Under multiple air pressure requirements, the user does not need to set up and arrange multiple independent air paths. The adjustment function of the electro-proportional valve can efficiently and conveniently meet various air pressure requirements. When the user selects channel B for air supply, the compressed gas does not pass through the electro-proportional valve but flows directly out of the outlet, simplifying the air supply process.

[0016] In addition, a one-way valve A is installed at the outlet end of channel A, and a one-way valve B is installed at the outlet end of channel B. When the gas outlet is supplied in reverse, a seal can be achieved, thereby preventing the gas from flowing back. Attached Figure Description

[0033] The electro-proportional valve 152 is a device that uses electrical signals to control gas pressure and flow. It has the advantages of stepless adjustment, remote control, high precision, and strong stability. The electro-proportional valve 152 is prior art. Its structure and working principle can be found in Chinese patent application (publication number: CN207064793U) and Chinese patent application (publication number: CN119267626A). Since the basic structure / principle of the electro-proportional valve 152 has been disclosed in the prior art, it will not be described in detail here.

The two-position two-way solenoid valve is existing technology. The basic structure / principle of the two-position two-way solenoid valve has been disclosed in the existing technology, so it will not be described in detail here.

[0039] The multifunctional integrated valve described in this utility model has two internal air supply channels, which users can flexibly choose according to their actual needs. These two air supply channels are channel A and channel B, and each channel can be controlled independently. When the user selects channel A for air supply, the compressed gas passes through the electro-proportional valve 152, and flows out to the outlet 21 after pressure regulation by the electro-proportional valve 152. This allows for precise and stepless adjustment of gas pressure (or flow rate), rather than simple on / off control. When the user selects channel B for air supply, the compressed gas does not pass through the electro-proportional valve 152 but flows directly out of the outlet 21, simplifying the air supply process.

[0040] In addition, a one-way valve A241 is installed in the gas outlet channel A and a one-way valve B251 is installed in the gas outlet channel B. When gas is supplied in reverse at the outlet end, it can be sealed by the one-way valve to prevent gas backflow and protect the independence of the gas at the outlet end.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
