How long is the response time of SMC solenoid valve

Date:2018-04-17 Author: Click:

The response time of the SMC solenoid valve can be as short as several milliseconds, and even the pilot solenoid valve can be controlled within dozens of milliseconds. Due to its self-contained loop, it is more sensitive than other self-controlled valves. The properly designed electromagnetic valve coil power consumption is very low, which is an energy-saving product; It can also be done only by touching the action, automatically maintaining the valve position, usually does not consume electricity at all. Electromagnetic valve shape size small, not only save space, but also light and beautiful. The adjustment precision of electromagnetic valve is limited, and the applicable medium is limited. The SMC solenoid valve usually has only two states of switch. The valve core can only be in two limit positions and can not be continuously adjusted.(There are many new ideas that try to break through, but they are still in the trial stage), so the adjustment accuracy is also limited. The SMC solenoid Valve has high requirements for the cleanliness of the medium, and the granular medium can not be applied. If it is an impurity, it must be filtered first. In addition, viscous media can not be applied, and the viscosity range of media suitable for specific products is relatively narrow. The SMC solenoid Valve has a variety of models and a wide range of uses. Although the electromagnetic Valve has a congenital deficiency, the advantages are still very prominent. Therefore, it is designed into a variety of products to meet various needs and has a wide range of uses. The progress of electromagnetic valve technology is also centered on how to overcome congenital defects and how to better exert its inherent advantages.
First, there are two types of SMC solenoid valves: open and open. The closed type is closed when the power is turned off. When the coil is energized, electromagnetic force is generated, so that the dynamic iron core can overcome the spring force and the static iron core suction directly open the valve. The medium is a path; When the coil is powered off, the electromagnetic force disappears, the moving core is reset under the action of the spring force, and the SMC solenoid valve is directly closed. The valve mouth and medium do not pass. The structure is simple, the action is reliable, and the zero pressure difference and microreal. Work normally under air. The constant opening type is just the opposite. Such as an electromagnetic valve less than φ 6 flow diameter. (Figure 1 is a typical structure diagram) Two, step by step vertical type solenoid valve This valve adopts a single valve and a secondary valve. The main valve and the guide valve step so that the electromagnetic force and pressure difference directly open the main valve. When the coil is energized, an electromagnetic force is generated to allow the moving core and the static core to suck. The guide valve opening and the guide valve opening are located on the main valve opening, and the moving core is connected to the main valve core. At this time, the pressure of the main valve upper cavity is discharged through the guide valve opening. At the same time as the pressure difference and the electric magnetic force, the main valve core is moved upwards to open the main valve medium circulation. When the coil is powered off, the electromagnetic force disappears. At this time, the moving iron core closes the guide valve hole under the action of the weight and spring force. At this time, the medium enters the main valve core cavity in the balance Kongzhong, The upper cavity pressure is increased. At this time, the main valve is closed under the action of spring reset and pressure. The medium is cut off. The structure is reasonable, the action is reliable, and the work is reliable at zero pressure difference. Such as: ZQDF, ZS, 2W, etc..
