Problems solved by technology

[0002] Solenoid valves are the key actuators in the widely used automation control technology in the current manufacturing field. At present, the miniature solenoid valves on the market can be divided into several categories according to their working principle, structure and manufacturing process: direct-acting solenoid valves valve, direct-acting solenoid valve, and guide solenoid valve. These three types of solenoid valves currently on the market all have large volume, complex structure, irregular structure, small flow capacity, large working current, easy heating of the coil, and cannot be used for a long time. time work issues

Abstract

The invention discloses an embedded negative pressure solenoid valve for a milk liquid metering device and its working method. The spool has a mounting hole on the spool, and the spring is installed on the spool through the mounting hole. The valve body includes power leads, invisible air inlets, and coils. The power leads are set on the side of the valve body, the invisible air inlets are set on the bottom of the valve body, and the coils are set between the valve body and the valve core and are attached to the cylindrical track. . Both the top and the bottom of the spool are provided with installation grooves, and top and bottom soft plugs are respectively installed in the installation grooves. The two sides of the spool are provided with vertical and relatively established track air passages. The invention has the advantages of simple structure, small volume, regular appearance, easy installation and built-in, fast response speed of the solenoid valve, and the design of the track gas circuit makes it possible to take away a large part of the heat generated by the coil when the negative pressure flows through the track gas circuit, thereby increasing Coil life and overall product life.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to an embedded negative pressure solenoid valve for a milk liquid metering device and a working method thereof. Background technique [0002] Solenoid valve is the key executive element in the automation control technology widely used in the current manufacturing field. At present, the miniature solenoid valves on the market can be divided into several categories according to the working principle, structure and manufacturing process: direct acting solenoid Valves, direct-acting solenoid valves, and guided solenoid valves, these three types of solenoid valves currently on the market all have large volume, complex structure, irregular structure, small flow capacity, large working current, easy heating of the coil, and cannot be used for a long time. time work etc. [0003] With the rapid development of modern pastures, especially the rapid development of pasture metering devices, higher requireme...
