Rocker-arm membrane valve

Abstract

The invention discloses a rocker-arm membrane valve. According to the interior of the rocker-arm membrane valve, a traditional solenoid electromagnet is designed to be a novel beating electromagnet suitable for the membrane valve, and a traditional fulcrum located at the center of a valve body is changed to be arranged at the right end of an armature frame at the lower end; and a contact point ofan armature and a rocker arm is right located at the force-arm far end of the rocker arm, so that the shaft shifting design is not needed, the size of the electromagnet can be better reduced, and thestructure is more compact. The beating electromagnet is adopted, the armature is separated from an electromagnetic coil, so that reducing of the thickness of the electromagnet is facilitated, and theeffect of the ultra-thin design of the electromagnet valve is prominent; the position of an air gap of the electromagnet is changed to the edge from the middle, so that the value is naturally increased, and the suction of the electromagnet of the electromagnetic valve is improved; and meanwhile, the response speed is increased, the power of the electromagnetic valve can be reduced, and the volumeof the electromagnetic valve is reduced.

【Technical field】 [0001] The invention belongs to the technical field of fluid control, and in particular relates to a rocker-arm diaphragm valve. 【Background technique】 [0002] Most of the structures of the existing rocker diaphragm valves are as follows: figure 1 As shown in the figure, using a solenoid electromagnet, the central axis of the electromagnet and the central axis of the valve body are staggered by a certain distance, and the armature moves vertically on the central axis of the electromagnet. The solenoid electromagnet needs to move with the valve body. The shaft design makes the electromagnetic suction directly act on the unilateral force arm, and the solenoid valve is not compact in structure and has a large volume. Moreover, the motion transmission between the electromagnet and the rubber diaphragm is relatively complicated, and the frictional resistance is large.

Problems solved by technology

[0002] Most of the structures of the existing rocker diaphragm valves are as follows: figure 1 As shown in the figure, using a solenoid electromagnet, the central axis of the electromagnet and the central axis of the valve body are staggered by a certain distance, and the armature moves vertically on the central axis of the electromagnet. The solenoid electromagnet needs to move with the valve body. The shaft design makes the electromagnetic suction directly act on the unilateral force arm. The structure of the solenoid valve is not compact and the volume is large.

Moreover, the motion transmission between the electromagnet and the rubber diaphragm is relatively complicated, and the frictional resistance is large. The electromagnetic suction force generated by the electromagnet cannot be efficiently used for the effective sealing of the solenoid valve, so the power consumption of the solenoid valve is relatively high.
