Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] like Figure 1-3 As shown, the utility model provides a long-life electromagnetic pulse valve, including a coil 1, a pressure plate 5 is arranged at the lower end of the coil 1, an upper cover 7 is arranged at the lower end of the pressure plate 5, screw holes are provided on the top walls of the pressure plate 5 and the upper cover 7, a pressure plate screw 6 is provided on the upper end of the pressure plate 5, a lower body 10 is arranged at the lower end of the upper cover 7, screw holes are provided on the top walls of the upper cover 7 and the lower body 10, and an upper cover screw 8 is provided on the upper end of the upper cover 7.

[0025] Specifically, a label 2 is provided on the front of the coil 1. The advantage is that the label 2 can be used to indicate the name of the item.

[0026] Specifically, the lower end of the coil 1 is provided with a guide column 4, the top wall of the pressure plate 5 is provided with a mounting groove, and the guide column 4 is installed inside the mounting groove of the top wall of the pressure plate 5. The advantage is that the guide column 4 is divided into two parts, the pilot head and the guide column. The function of the pilot head is to resist the airflow when the gas pressure is unloaded. The pilot head is an actuator matched with the solenoid valve and is an important driving component of the solenoid valve. It has a base connected to the valve body and is used to install the static and dynamic iron core components.

[0027] Specifically, a diaphragm 9 is provided at the lower end of the upper cover 7, a lower body 10 is provided at the lower end of the diaphragm 9, and an output port 11 is provided on the bottom wall of the lower body 10. The advantage is that the setting of the diaphragm 9 has fast response and precise control. In the electromagnetic pulse valve, the diaphragm 9 can act quickly after receiving the electrical signal by virtue of its excellent elasticity and fast response ability, so that the valve can complete the opening and closing operation within milliseconds, and realize the precise control of the medium flow. It is also an important role in the dust cleaning system. The quality of the diaphragm 9 directly affects the dust cleaning effect and the service life of the filter bag, and it also has good durability and life.

[0028] Embodiment 2:

[0029] like Figure 1-3As shown, as an improvement to the previous embodiment. Specifically, a retaining spring 3 is arranged at the upper end of the coil 1, a spring is arranged inside the guide column 4, and a spring is arranged between the upper cover 7 and the diaphragm 9. The advantage is that a spring is arranged inside the guide column 4, and the arrangement of the spring inside the guide column 4 closes the pilot hole with the spring force when the power is off, and the inlet pressure quickly passes through the bypass hole to form a pressure difference around the closing valve member, which is low at the bottom and high at the top. The fluid pressure pushes the closing member to move downward, thereby closing the valve.

[0030] When in use, after the utility model is installed, when using the electromagnetic pulse valve body, it is first moved to the working area, and then the external power supply is turned on. At this time, the current inputs a pulse signal to the coil 1 in the electromagnetic pulse valve body through the wire, and the electromagnetic pulse valve body is controlled by the output signal of the pulse injection controller. Relying on the pressure changes of the front air chamber and the rear air chamber inside the electromagnetic pulse valve body, the diaphragm 9 is flexed and deformed to realize the opening and closing of the electromagnetic pulse valve body. The guide column 4 is divided into a pilot and a guide column. A spring is arranged inside the pilot. The setting of the spring inside the guide column 4 closes the pilot hole with the spring force when the power is off. The inlet pressure quickly forms a pressure difference of low down and high up around the closing valve member through the bypass hole. The fluid pressure pushes the closing member to move downward, thereby closing the valve so that the diaphragm 9 is not easily damaged. At the same time, the setting of the pressure plate screw 6 and the upper cover screw 8 is convenient for the user to disassemble and install the replacement device, thereby extending the service life of the electromagnetic pulse valve body. When the electromagnetic pulse valve body is used up, the external power supply can be turned off.
