Description

Technical Field

[0001] This utility model relates to the field of gas valves, specifically to a new energy gas valve. Background Technology

[0002] The gas valve for new energy vehicles is a gas control device specifically designed for these vehicles. By regulating gas flow and pressure, it ensures the safe and efficient operation of the fuel supply system. Its core functions include precise opening and closing, flow control, pressure regulation, and leakage protection. It typically employs an electric actuator or pneumatic drive, combined with an intelligent control system to achieve real-time response and fault diagnosis. This valve possesses high sealing performance, corrosion resistance, and vibration resistance, adapting to complex vehicle operating conditions while meeting environmental requirements for low emissions and high reliability, providing crucial fuel delivery assurance for the power system of new energy vehicles.

[0003] CN101660466A discloses an automotive gas injection valve. An output gas distribution device is provided at the outlet end of the valve body. This device includes a housing, a gas distribution chamber within the housing, and at least one discharge channel located below and communicating with the gas distribution chamber. The valve body includes a switch for opening and closing the outlet. It also includes an adjustment device for regulating the output flow rate of the outlet. This device includes a plug, a nut, and a lead screw. One end of the lead screw passes through the plug and is threadedly engaged with the nut. The flow rate passes through the outlet and then into the gas distribution chamber. The gas distribution chamber then passes through multiple discharge channels and supplies gas to cylinders, achieving the goal of simultaneously injecting gas from one injection valve to multiple cylinders. This technology uses a lead screw to adjust the output gas volume, which has limited adjustment accuracy, slow adjustment speed, and is susceptible to mechanical wear, leading to adjustment lag or loosening, thus affecting the stability and control accuracy of the gas supply. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a new energy gas valve to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new energy gas valve, comprising a gas valve body, an inlet on one side of the gas valve body, and an outlet on the side of the gas valve body away from the inlet. The gas valve body is characterized by having a connecting hole at the end away from the outlet, a magnetic valve seat connected to the connecting hole, and the gas valve body communicating with the magnetic valve seat through the connecting hole. At least three solenoid valves are connected in parallel on the top of the valve body, and the outlet is located on the side of the magnetic valve seat away from the connecting hole. Each solenoid valve can control the outlet to deliver different gas volumes.

[0006] Using the above technical solution, the solenoid valve seat and the gas valve body are connected through a connection hole. At least three solenoid valves connected in parallel at the top can independently control the gas flow at the outlet. At least three solenoid valves can achieve at least seven different gas outputs to meet different usage needs and achieve energy saving. Using solenoid valves for control avoids the problems of limited adjustment accuracy and slow adjustment speed of traditional screw control. Under long-term use, wear will not cause changes in gas output, which greatly improves the stability of gas supply.

[0007] The aforementioned new energy gas valve can be further configured such that: the solenoid valve seat has an air inlet channel communicating with the connection hole and an air outlet channel communicating with the air outlet hole; the air inlet channel and the air outlet channel are vertically arranged with at least three adjustment channels; the adjustment channels are communicating with the air inlet channel and the air outlet channel; and the solenoid valve can control the air inlet volume in the adjustment channels to cause the air outlet to deliver different air volumes.

[0008] Using the above technical solution, at least three regulating channels are set vertically between the air intake channel and the air outlet channel, realizing multi-level diversion and independent control of the gas flow direction; the solenoid valve regulates the total gas output of the outlet by adjusting the air intake in each channel, so as to meet the gas supply needs under different working conditions.

[0010] Using the above technical solution, the coil assembly on the outer periphery of the stationary iron core generates a magnetic field after being energized, which drives the moving iron core assembly to move axially, thereby causing the valve body adjusting rod to move axially within the adjusting channel, thus realizing multi-stage control of the gas flow rate; different current intensities or pulse signals can adjust the displacement of the moving iron core, thereby changing the gas output of the outlet.

[0011] The aforementioned new energy gas valve can be further configured such that: an air inlet valve is detachably installed on one side of the gas valve body; the air inlet valve includes a connecting part detachably connected to the gas valve body and an air inlet connecting pipe connected to the outside; the air inlet is located on one side of the air inlet connecting pipe; and an opening / closing valve capable of opening or closing the air inlet connecting pipe is provided at the top of the air inlet connecting pipe.

[0012] The above technical solution allows for a detachable connection between the intake valve and the gas valve body, facilitating disassembly and maintenance. The on / off valve at the top of the intake connection pipe can independently control the flow of the external gas source, ensuring safety.

[0013] The aforementioned new energy gas valve can be further configured such that: a connecting protrusion is provided at one end of the gas valve body facing the connecting part; a first sealing gasket is provided between the connecting part and the connecting protrusion; connecting ears are symmetrically provided at both ends of the connecting protrusion and the connecting part; and the connecting ears are provided with fixing holes for fixing the connecting protrusion and the connecting part.

[0014] Using the above technical solution, the connecting protrusion at the end of the gas valve body facing the connecting part is fitted with the connecting part through the first sealing gasket, effectively preventing gas leakage; the symmetrically arranged connecting ears and fixing holes ensure that the intake valve will not loosen due to vibration or pressure impact during installation or maintenance.

[0015] The aforementioned new energy gas valve can be further configured such that: both ends of the gas valve body are provided with mounting blocks, the mounting blocks are equipped with L-shaped mounting plates, the L-shaped mounting plates are detachably connected to the mounting blocks, the vertical surface of the L-shaped mounting plates is provided with a plurality of mounting holes for external installation, and a second sealing gasket is provided between the horizontal surface of the L-shaped mounting plates and the gas valve body.

[0016] With the above technical solution, the mounting blocks at both ends of the gas valve body are detachably connected to the L-shaped mounting plate. The mounting holes on the vertical surface of the L-shaped mounting plate can be directly connected to external equipment. The second sealing gasket between the horizontal surface and the gas valve body effectively prevents gas leakage, ensures system safety, and improves the shock resistance and stability of the gas valve.

[0017] The beneficial effects of this utility model are as follows: the magnetic valve seat and the gas valve body are connected through the connecting hole, and at least three solenoid valves arranged in parallel can independently control the gas flow at the gas outlet. At least three solenoid valves can achieve at least 7 different gas outputs. The gas output will not change due to wear during long-term use, which greatly improves the stability of gas supply.
