Description

Technical Field

[0001] This utility model relates to the field of gas control technology, specifically to a gas control device and generator for a multi-fuel generator. Background Technology

[0002] Multi-fuel generator sets on the market generally use natural gas or liquefied petroleum gas (LPG) as fuel. Due to significant fluctuations in gas stability, a pressure regulating valve is required between the gas source and the reciprocating internal combustion engine-driven generator set for stabilization. Furthermore, to facilitate quick and easy adjustment of the gas flow rate, a gas flow switch is typically installed between the pressure regulating valve and the generator set. This setup not only increases the overall installation cost but also, because both the pressure regulating valve and the gas flow switch are separately connected within the generator set, increases the number of connection points on the internal piping, significantly increasing the risk of gas leakage during operation. Therefore, it fails to meet user requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a gas control device and a generator for a multi-fuel generator. When applied to a multi-fuel generator, the gas control device can efficiently and simply adjust the flow rate of different gases.

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

[0005] In the first aspect, a gas control device for a multi-fuel generator is proposed, including a pressure regulating valve, a solenoid valve, and a fuel selection mechanism;

[0006] The pressure regulating valve has an integrally formed pressure regulating valve base on its outer shell, and the pressure regulating valve base is configured as a three-way structure; the air inlet of the pressure regulating valve is connected to the gas supply unit, and its air outlet is connected to the first channel of the pressure regulating valve base; the second channel of the pressure regulating valve base is sealed to an air outlet connector, and the second channel and the first channel are connected to form a gas passage inside the pressure regulating valve base; the solenoid valve is located outside the air inlet of the pressure regulating valve and is used to receive control signals to open or close the air inlet of the pressure regulating valve;

[0007] The fuel selection mechanism includes a fuel selection unit and a flow regulating valve core, the flow regulating valve core being connected to the fuel selection unit; the fuel selection unit is partially sealed within the third channel of the pressure regulating valve base, used to indicate the gas type available to the multi-fuel generator and determine the gas type currently selected by the multi-fuel generator; the flow regulating valve core is disposed within the gas passage of the pressure regulating valve base, used to regulate the gas flow rate delivered to the engine according to the gas type currently selected by the multi-fuel generator determined by the fuel selection unit.

[0008] Furthermore, the fuel selection unit is fixedly and sealed to the third channel of the pressure regulating valve base;

[0009] The fuel selection unit is configured as a flow selection knob, which has a degree of freedom to rotate about its axis within the third channel. When the flow selection knob is rotated, it drives the flow regulating valve core to change position within the gas channel, thereby changing the radial dimension of the gas channel to adjust the flow rate.

[0010] Furthermore, the first and second channels formed within the pressure regulating valve base are both connected to the third channel, which is configured as a cylindrical channel.

[0011] Furthermore, the portion of the flow regulating valve core located within the gas passage is configured as a rectangular plate structure coaxial with the cylindrical passage. The radial dimension of the rectangular plate structure is adapted to the diameter of the cylindrical passage, and several vent holes are provided on the surface of the rectangular plate structure. When the flow selection knob is rotated within the third passage, it drives the rectangular plate structure to rotate within the gas passage, thereby adjusting the flow rate at the gas outlet of the gas passage.

[0012] Furthermore, the end of the flow selection knob furthest from the pressure regulating valve base is configured as the flow selection knob.

[0013] Furthermore, the rotation angle range of the flow selection knob on the pressure regulating valve base is 0 to 90°;

[0014] When the rotation angle of the flow selection knob is 0, the surface of the rectangular plate structure is perpendicular to the axial direction of the gas passage, and the gas is delivered to the engine through the vent hole on the rectangular plate structure.

[0015] When the flow rate selection knob is rotated at 90°, the surface of the rectangular plate structure is parallel to the axial direction of the gas passage, and the gas is delivered to the engine through the channel formed between the wall of the gas passage and the surface of the rectangular plate structure.

[0016] Secondly, a multi-fuel generator is proposed, wherein the gas pipeline of the multi-fuel generator is equipped with the aforementioned gas control device for multi-fuel generators.

[0017] As can be seen from the above technical solutions, the technical solutions of this utility model have achieved the following beneficial effects:

[0018] This utility model discloses a gas control device and generator for a multi-fuel generator. The gas control device for the multi-fuel generator includes a pressure regulating valve, a solenoid valve, and a fuel selection mechanism.

A second channel of the pressure regulating valve base is sealed to an outlet connector, and the second channel and the first channel are interconnected to form a gas passage inside the pressure regulating valve base. The solenoid valve is located outside the inlet of the pressure regulating valve and is used to receive control signals to open or close the inlet of the pressure regulating valve.

The fuel selection unit is used to determine the gas type currently selected by the multi-fuel generator, and the flow regulating valve core is located inside the gas passage to regulate the gas flow. This gas control device, when applied to a multi-fuel generator, can select gas type and conveniently and efficiently adjust the gas flow. Furthermore, the gas control device integrates gas on / off control, resulting in a higher overall integration level.

[0033] Currently, multi-fuel generators using two types of gas typically require gas flow regulation during operation. Existing technologies regulate flow by installing manual regulating valves on the gas pipeline or by installing automatic flow control devices on the gas pipeline. However, both methods suffer from issues such as incomplete regulation and high costs. To address these problems, this invention proposes a gas control device for multi-fuel generators. This device integrates gas on / off control and gas flow control, making it more convenient and efficient to use.

[0034] The gas control device and generator for multi-fuel generators disclosed in this utility model will be further described in detail below with reference to the accompanying drawings.

[0035] Combination Figures 1 to 7 As shown, the gas control device for a multi-fuel generator disclosed in this utility model includes a pressure regulating valve 1, a solenoid valve 2, and a fuel selection mechanism 3. The design structure is as follows: a pressure regulating valve base 1.1 is provided on the outer shell of the pressure regulating valve 1, and the pressure regulating valve base 1.1 is configured as a three-way structure; the inlet of the pressure regulating valve 1 is connected to a gas supply unit, such as a gas cylinder, and its outlet is connected to the first channel of the pressure regulating valve base 1.1; a second channel of the pressure regulating valve base 1.1 is sealed to an outlet connector 4, and the second channel and the first channel are connected to form a gas passage inside the pressure regulating valve base 1.1; the solenoid valve 2 is located outside the inlet of the pressure regulating valve 1 and is used to receive control signals to open or close the inlet of the pressure regulating valve 1, i.e., the solenoid valve 2 controls... Gas flow control; the fuel selection mechanism 3 includes a fuel selection unit and a flow regulating valve core 3.2. The flow regulating valve core 3.2 is integrally formed with the fuel selection unit, and they work together to adjust the gas flow. The fuel selection unit is partially sealed in the third channel of the pressure regulating valve base 1.1, and the flow regulating valve core 3.2 is disposed in the gas channel of the pressure regulating valve base 1.1. In use, the fuel selection unit is used to indicate the gas type that the multi-fuel generator can use and to determine the gas type currently selected by the multi-fuel generator. The flow regulating valve core 3.2 is used to adjust the gas flow delivered to the engine according to the gas type currently selected by the multi-fuel generator determined by the fuel selection unit.

[0036] The embodiment connects the fuel selection unit and the flow regulating valve core 3.2 so that the generator can directly adjust the gas passage to the flow rate required for fuel selection when selecting gas, without missing any operations.

[0037] Further integration Figure 1As shown, the fuel selection unit is fixedly and sealed to the third channel of the pressure regulating valve base 1.1. The fuel selection unit is configured as a flow selection knob 3.1, which has a degree of freedom to rotate about its axial direction within the third channel. When the flow selection knob 3.1 rotates, it drives the flow regulating valve core 3.2 to change position within the gas passage, thereby changing the radial dimension of the gas passage to adjust the flow rate. In the illustrated embodiment, the gas passage formed by the first and second channels is an L-shaped passage, meaning that the first and second channels of the pressure regulating valve base 1.1 are not on the same straight line. Optionally, for ease of processing, the first and second channels can be arranged on the same straight line, in which case the gas passage formed is a straight-line passage.

[0038] In the embodiment shown in the attached figure, the first and second channels formed within the pressure regulating valve base 1.1 are both connected to a third channel, which is configured as a cylindrical channel. The portion of the flow regulating valve core 3.2 located within the gas passage is configured as a rectangular plate structure coaxial with the cylindrical channel. The radial dimension of the rectangular plate structure along the cylindrical channel is adapted to the diameter of the cylindrical channel, and the plate surface of the rectangular plate structure is provided with several vent holes 4.1, with at least one vent hole 4.1 in this embodiment. When the flow selection knob 3.1 rotates within the third channel, it drives the rectangular plate structure to rotate within the gas passage, thereby adjusting the flow rate at the gas outlet of the gas passage. Figure 5 and Figure 7 As shown.

[0039] In the diagram, the flow selection knob 3.1 is located at the end of the fuel selection mechanism 3 away from the pressure regulating valve base 1.1, and its rotation angle range on the pressure regulating valve base 1.1 is 0 to 90°. In the illustrated embodiment, a vent hole 4.1 is provided through the center of the rectangular plate structure. Therefore, when the flow selection knob 3.1 rotates to 0°, the surface of the rectangular plate structure is perpendicular to the axial direction of the gas passage, and the gas is delivered to the engine through the vent hole 4.1 on the rectangular plate structure. Figure 7 As shown; when the flow selection knob 3.1 is rotated to 90°, the surface of the circular plate structure is parallel to the axial direction of the gas passage, and the gas is delivered to the engine through the channel formed between the wall of the gas passage and the surface of the rectangular plate structure, as shown. Figure 5As shown. The rotation angle of the flow selection knob 3.1 is set mainly to facilitate the use of multi-fuel generators. In some scenarios, the flow adjustment can be completed by rotating the flow selection knob 3.1 to a certain angle. In the embodiment, 0 and 90° are the minimum and maximum values ​​for flow adjustment under the design of this scheme. In some embodiments, the rectangular plate structure does not have vent holes 4.1 on its surface. The flow can be adjusted directly by its rotation angle in the gas passage, which can also achieve the same technical effect as this scheme.

[0040] The gas control device for multi-fuel generators described above, when used on multi-fuel generators, can simultaneously achieve gas on / off control and gas flow regulation, which is convenient and efficient.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
