Abstract

The utility model provides an electromagnetic pulse valve, comprising a first valve body, a second valve body, a third valve body, a first diaphragm, a second diaphragm, a valve cover and an electromagnetic valve. The valve is divided into a first air chamber, a second air chamber and a third air chamber by the first diaphragm and the second diaphragm. The electromagnetic impulse valve is mainly used for blowing and ash cleaning systems. The high pressure air in the third air chamber, the second air chamber and the first air chamber is exhausted into atmosphere in turn by the working of the electromagnetic valve; therefore, the second diaphragm and the first diaphragm are driven in turn to move, the blowing process is finished. The electromagnetic impulse valve has large pressure, the blowing time is 0. 1 second or so every time, and the service lives of the diaphragms are long.

Description

Electromagnetic impulse valve

Technical field

The utility model relates to a kind of electromagnetic impulse valve.

Background technique

In the prior art, for the winding-up that solves single-iris electromagnetic impulse valve hypotony, problems such as flow is too little, usually will two diaphragms be set in the electromagnetic impulse valve, wherein a principal oscillation diaphragm is sealed the air outlet, close together and form a less air chamber between the moving core of another control diaphragm and a solenoid valve, when solenoid valve is opened, moving core is picked up, stingy indoor high-pressure air is discharged from controlling in the hole on the diaphragm, control diaphragm then and be lifted, drive the principal oscillation diaphragm again, to finish the process of jetting deashing.Though this electromagnetic impulse valve is bigger slightly than the electromagnetic impulse valve pressure of single-iris, its pressure still has only 5-7kg/cm ², winding-up tolerance is still lower, and the winding-up effect is good inadequately.

Summary of the invention

The utility model purpose provides a kind of electromagnetic impulse valve, and it overcomes the deficiencies in the prior art, has bigger pressure and winding-up tolerance.

For achieving the above object, the technical solution adopted in the utility model is: a kind of electromagnetic impulse valve, the primary diaphragm that comprises first valve body with suction port and air outlet, second valve body that the underpart is connected with described first valve body, described first valve body and second valve body are separated, the valve gap that is positioned at second valve body top, described primary diaphragm is provided with first gas port.The described primary diaphragm and first valve body form first air chamber, and the described primary diaphragm and second valve body form second air chamber.Described primary diaphragm is sealed the air outlet, and is provided with first spring between the primary diaphragm and second valve body.Be connected with solenoid valve on the described valve gap, have the core of deciding and moving core in the described solenoid valve, describedly decide to be provided with the 3rd spring between core and the moving core.Be provided with the 3rd valve body between described second valve body and the valve gap, be provided with secondary diaphragm between described second valve body and the 3rd valve body.Have first exhaust port on described second valve body, described secondary diaphragm is sealed first exhaust port, and described secondary diaphragm is provided with second gas port, is provided with second spring between described secondary diaphragm and described the 3rd valve body.Form the 4th air chamber between described secondary diaphragm and described second valve body, form the 3rd air chamber between described secondary diaphragm and described the 3rd valve body.Have second exhaust port on described the 3rd valve body, described moving core is sealed described second exhaust port.

Because technique scheme utilization, the utility model compared with prior art has following advantage: be provided with the 3rd valve body between second valve body and valve gap, and secondary diaphragm separates second valve body and the 3rd valve body, have second exhaust port on the 3rd valve body, this second exhaust port is sealed by the moving core of solenoid valve.When solenoid valve was opened, moving core was picked up, and the high-pressure air in the 3rd air chamber can be discharged to the atmosphere from second exhaust port immediately, and secondary diaphragm and primary diaphragm are lifted successively then, thereby finish the process of winding-up.This electromagnetic impulse valve not only jetting pressure is big, and winding-up tolerance is very big, and speed is very fast.
