Description

Technical Field

[0001] The utility model relates to the technical field of injection valves, in particular to an independently installed electromagnetic injection valve. Background Art

[0002] In the electronic machinery, medical equipment, high-precision equipment and other industries, jet valves are used to dispense small amounts or small droplets of high-viscosity substances onto substrates or workpieces in a non-contact manner. Such high-viscosity substances generally include flux, solder paste, adhesives, oils, sealing polymers, silicones and other compounds. Usually, such high-viscosity substances will not flow under their own gravity at room temperature. When used, they generally need to be injected into the jet valve, and then dispensed to the substrate or workpiece in small amounts or droplets by the jet valve.

[0003] In this regard, China applied for patent number: CN203540803U, which discloses a spray device, and more particularly, relates to an electromagnetic spray valve. The working principle of the utility model is: the power supply of the electromagnetic drive device is closed, and the electromagnet generates magnetic force when it is energized. The magnetic force attracts the movable seat, forcing the movable seat to move upward, and the striker is fixed to the movable seat, so the movable seat will simultaneously drive the striker to move upward. When the striker moves upward, the channel of the nozzle is opened; at this time, the power supply is disconnected, the magnetic force disappears, and the movable seat moves downward rapidly under the action of the return spring, thereby realizing the extrusion and spraying of the paint. The electromagnetic spray valve is controlled by an electromagnetic drive device, which is easy to operate and has a simple structure. Moreover, this electromagnetic control has the advantages of fast response speed and stable operation. In actual use, the effect is remarkable.

[0004] However, in actual use, the electromagnetic drive device has poor stability and poor limiting effect when installed inside the shell. At the same time, the electromagnetic drive device cannot be independently limited and fixed after installation inside the shell, so it has certain limitations during installation. Therefore, it has become an urgent problem to be solved to perfect and improve the above problems. Utility Model Content
