Technical Field

[0001] The utility model belongs to the technical field related to hydrogen bottle valves, and particularly relates to an electromagnetic pilot device for an integrated hydrogen bottle valve. Background Technique

[0002] This electromagnetic pilot device is an electromagnetic pilot valve. When the solenoid valve is energized, the moving iron core in the temporal part can be lifted upward under the action of electromagnetic force, opening the processing pilot hole. The air flow first enters from the pilot hole, making the pressure difference inside and outside the valve gradually equal, thus opening the valve.

[0003] However, when the integrated hydrogen bottle valve electromagnetic pilot device is in use, it is very difficult to detect and handle air leakage in a timely manner when it occurs at the connection port position. Therefore, it is very easy to cause gas leakage, resulting in waste of resources and environmental pollution.

[0004] The utility model improves the above problems and particularly relates to an electromagnetic pilot device for an integrated hydrogen bottle valve with automatic air leakage closure. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electromagnetic pilot device for an integrated hydrogen bottle valve, so as to solve the problem that when the integrated hydrogen bottle valve electromagnetic pilot device is in use, it is very difficult to detect and handle air leakage in a timely manner when it occurs at the connection port position.

After the gas enters the connecting outlet pipe, it will enter the inner lateral rubber airbag, causing the inner lateral rubber airbag to expand and making the lower side of the inner lateral rubber airbag closely adhere to the inner side surface of the inner annular groove to block the connecting outlet pipe.

[0009] Preferably, an inlet and outlet column is arranged at the left side position near the upper end of the outer connecting ring. The inlet and outlet column and the connecting outlet pipe are of an integral structure. An external thread is arranged at the outer side position of the inlet and outlet column.

An air vent connecting pipe is provided at the inner position near the upper side of the outer connection ring. An inner lateral rubber airbag is provided at the end position of the air vent connecting pipe. An inner annular groove is provided at the outer side position of the inner lateral rubber airbag. The upper part of the inner lateral rubber airbag and the inner annular groove are connected by an adhesive. After the gas enters the connecting outlet pipe, it will enter the inner lateral rubber airbag, causing the inner lateral rubber airbag to expand and the lower side of the inner lateral rubber airbag to closely adhere to the inner side surface of the inner annular groove to block the connecting outlet pipe.
