Lever type one-way solenoid valve for high-pressure oil pump

Abstract

The invention discloses a lever type one-way solenoid valve for a high-pressure oil pump, and relates to the field of high-pressure oil pump accessory equipment. The one-way solenoid valve comprises apipe, wherein a second shell is fixed at the upper end of the pipe, a first shell is fixed to the upper end of the second shell, a fixed core is arranged in the first shell, coils are arranged at thetwo ends of the fixed core, a valve rod is fixed at the lower end of the fixed core, a first connecting rod is fixed at the lower end of the valve rod, the lower end of the first connecting rod penetrates through the second shell and extends into the second shell, a pin is arranged at the lower end of the first connecting rod, the rear end of the pin penetrates through the first connecting rod and is rotationally connected with a cross rod, the left end of the cross rod is fixedly provided with to a second connecting rod, the lower end of the second connecting rod penetrates through the second shell and extends into the pipe, the lower end of the second connecting rod is fixedly provided with a guide valve, the lower side of the guide valve is provided with a connecting cover, the guide valve extends into the connecting cover, and the lower end of the connecting cover is fixed to the upper surface of a main valve. According to the solenoid valve, the flow resistance of a large-caliberpipeline is convenient, the electric quantity is reduced, the service life of the solenoid valve is prolonged, and the solenoid valve is suitable for popularization.

Description

technical field [0001] The invention relates to the field of accessories for high-pressure oil pumps, in particular to a lever-type one-way solenoid valve for high-pressure oil pumps. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic force. It is an automatic basic component used to control fluid. Conventional solenoid valve generally pulls the movable iron core to move or reset by electromagnetic force. There is a seal on the movable iron core to directly control the main valve. We know that solenoid valves of different calibers are under different pressures. The larger the caliber, the higher the pressure, the greater the force required to move the movable iron core. This force is generated by the electromagnetic force of the electromagnetic coil. Therefore, in this case, the power or volume of the electromagnetic coil is required to be larger, which is not conducive to the compact design of the electromagnetic valve. ...

[0002] Solenoid valve is an industrial equipment controlled by electromagnetic force. It is an automatic basic component used to control fluid. Conventional solenoid valve generally pulls the movable iron core to move or reset by electromagnetic force. There is a seal on the movable iron core to directly control the main valve. We know that solenoid valves of different calibers are under different pressures. The larger the caliber, the higher the pressure, the greater the force required to move the movable iron core. This force is generated by the electromagnetic force of the electromagnetic coil. Therefore, in this case, the power or volume of the electromagnetic coil is required to be larger, which is not conducive to the exquisite design of the electromagnetic valve.

[0003] Existing one-way solenoid valves for high-pressure oil pumps do not need a lever structure, so that they can only block the flow of pipelines with small oil volumes, and relatively large pipelines are usually matched with larger solenoid valves, which also consume less power. increase, the resistance will also increase, resulting in a decrease in the life of the battery valve, therefore, we propose a lever-type one-way solenoid valve for high-pressure oil pumps to solve the above problems
