Combined installation electromagnetic jet valve

Abstract

The invention relates to a combined installation electromagnetic jet valve, which comprises a main valve, a pilot valve and an aerial socket, wherein the main valve comprises a jet valve seat block, a main valve cylinder body, a piston seat, a main valve spring, a sealing body, a screw plug, a piston and a sealing ring; the pilot valve is arranged in the jet valve seat block and comprises a pilot valve spring, a seal cover, a discharge plug, a pilot head, a soft seal, a dynamic magnetic core, a nut, an electromagnet, a main valve cylinder body screw and a seal cover screw; and the piston in the main valve moves in the main valve cylinder body so as to realize opening and closing of a main valve oil port, and the pilot valve arranged in the jet valve seat block controls the position of the dynamic magnetic core in the pilot valve through the charge condition of the electromagnet so as to realize control of the switching of the oil port and further control the motion of the piston in the corresponding main valve. The jet valve realizes switching of the main valve through on and off of the electromagnet of the pilot valve, does not need to compress air, avoids the problem caused by use of compressed air drive, improves the response speed, has high combined installation integration degree, and effectively promotes the installation efficiency.

Description

technical field [0001] The invention relates to a spray valve, in particular to a spray valve used as a process lubricating cooling system on a nonferrous metal processing plate, strip and foil rolling mill. Background technique [0002] Usually the injection valve is installed in the injection beam box, according to the application, the driving element of the valve can move between the open and closed positions. [0003] At present, diaphragm jet valves or cylinder jet valves are commonly used in non-ferrous metal processing strip and foil rolling mills. From a structural point of view, the diaphragm jet valve relies on the movement of the diaphragm to realize the switch and seal, and the cylinder type jet valve relies on the movement of the piston to realize the switch and seal. Both forms need to be driven by compressed air. Due to the long transmission and discharge time of the compressed air pressure, the response speed of the injection valve is slow, and the compresse...

AI Technical Summary

Problems solved by technology

Due to the long transmission and discharge time of the compressed air pressure, the response speed of the injection valve is slow, and the compressed air pipeline needs to be well sealed. If the air leaks, it will directly cause the injection valve to fail.

For the diaphragm injection valve, if the diaphragm is not tightly sealed or damaged, rolling oil will escape into the compressed air and enter the electromagnetic air valve with the compressed air, causing the electromagnetic air valve to not work normally
