Description

Technical Field

[0001] This utility model relates to the field of gas valves, specifically to a new energy energy-saving 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-saving gas valve to address the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new energy energy-saving 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 a connecting pipe at the end away from the outlet, a magnetic valve seat connected to the connecting pipe, the gas valve body communicating with the magnetic valve seat via the connecting pipe, at least three solenoid valves connected in parallel on the top of the valve body, and the outlet located on the side of the magnetic valve seat away from the connecting pipe. 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 by a connecting pipe. The two solenoid valves set in parallel on the top of the valve body can independently control the gas flow at the outlet, 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. It will not wear out and cause changes in gas output under long-term use, which greatly improves the stability of gas supply.

[0007] The aforementioned new energy-saving gas valve can be further configured as follows: the solenoid valve seat has an inlet channel communicating with a connecting pipe and an outlet channel communicating with an outlet hole; the solenoid valve includes a housing, a stationary iron core assembly is provided inside the housing, a coil assembly is provided on the outer periphery of the stationary iron core, a movable iron core assembly is movably provided inside the stationary iron core assembly, a valve body adjusting rod is fixedly provided at the bottom of the movable iron core assembly, mounting columns are symmetrically provided on the solenoid valve seat, and mounting cavities for mounting the valve body adjusting rod are provided inside the mounting columns. The valve body adjusting rod can move axially within the mounting cavity. The outlet channel is axially connected to and communicates with the mounting cavity. The movable iron core assembly and the valve body adjusting rod are fixedly connected by a connecting rod. A conical plug is provided at one end of the valve body adjusting rod facing the connecting rod. A conical air port is provided on one side of the conical plug in the mounting cavity. The movable iron core assembly can drive the conical plug to different positions through the coil assembly, causing the conical air port and the outlet to deliver different amounts of air.

[0008] Using the above technical solution, after the coil assembly on the outer periphery of the stationary iron core is energized, it drives the moving iron core assembly to move axially, which in turn drives the valve body adjusting rod and the conical plug to move axially within the installation cavity. The gas flow rate is controlled by the cooperation between the conical plug and the conical gas port. Different current intensities can adjust the position of the conical plug, thereby changing the gas output of the gas outlet and realizing stepless adjustment of the gas supply.

[0009] The aforementioned new energy energy-saving 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.

[0010] 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.

[0012] 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.

[0013] The aforementioned new energy-saving 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.

[0014] 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.

[0015] The aforementioned new energy energy-saving gas valve can be further configured such that: a strip-shaped fixing plate is provided on one side of the gas valve body, the strip-shaped fixing plate is provided with a dust cover, and the dust cover is provided with a clearance groove at the L-shaped mounting plate and the air inlet valve.

[0016] Using the above technical solution, the strip fixing plate provides support for the dust cover, ensuring that its coverage area effectively protects the key components of the gas valve; the avoidance grooves set at the L-shaped mounting plate and the air inlet valve of the dust cover not only avoid interference with the installation structure, but also reduce the risk of dust and impurities entering the valve body and extend the service life of the equipment.

[0017] The beneficial effects of this utility model are as follows: the magnetic valve seat is connected to the gas valve body through a connecting pipe, and the two solenoid valves set in parallel on the top of the valve body can independently control the gas flow at the outlet. The gas output will not change due to wear during long-term use, which greatly improves the stability of gas supply. Attached Figure Description
