Problems solved by technology
[0003] However, when the current stepping motor is connected with the electromagnetic combination valve for use, the pipeline connection between the two will leak, resulting in liquid leakage, which will cause danger in the long run, and also waste resources extremely. Electromagnetic combination valve In the process of use, there is no corresponding protection device, so it cannot be protected

The invention discloses an electromagnetic combination valve for a stepping motor. The electromagnetic combination valve for the stepping motor comprises a combination valve body, wherein a first pipeis arranged at one end of the combination valve body; a second pipe is arranged at the other end of the combination valve body; a first working opening and a second working opening are successively formed in the upper surface of the combination valve body; the second working opening is formed on one side of the first working opening; and a protective cover sleeves the lower portion of the combination valve body. By the design mode of a fastening device, the two working openings can be connected with external pipelines in a fastened manner, leakage of liquid in the electromagnetic combinationvalve is avoided, and normal use of the electromagnetic combination valve is ensured; and by the design mode of clamped fixation of the protective cover, the electromagnetic combination valve can be protected, a good protecting effect is achieved, the service time of the electromagnetic combination valve is prolonged, and the electromagnetic combination valve is simple in structure, low in manufacturing cost and convenient to popularize.
Description
technical field [0001] The invention relates to the field of electromagnetic combination valves, in particular to an electromagnetic combination valve for a stepping motor. Background technique [0002] Stepping motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main executive element in modern digital program control systems and is widely used. The position only depends on the frequency and pulse number of the pulse signal, and is not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, which is called " Step Angle", its rotation is run step by step at a fixed angle, the angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, the speed and rotation speed of the motor can be controlled by controlling the ...
