A valve wiring channel is generally set in the high-pressure valve. The electrical circuit inside the high-pressure valve is connected to the external circuit through the valve wiring channel. During the wiring process of the electrical circuit inside the high-pressure valve and the external circuit, how to connect the circuit and seal the channel is the key to ensure the normal operation of the high-pressure valve. The connection and sealing structures of the electrical circuit inside the high-pressure valve and the external circuit currently used have the disadvantages of complex structure, inconvenient installation, and large space occupation.

[0005] Furthermore, the aforementioned high-pressure valve channel sealing wiring structure, wherein: the middle section of the wiring core is provided with a sealing sleeve positioning step protruding from the outer wall of the wiring core, and the insulating sealing sleeves mounted on both ends of the wiring core are respectively tightly attached to the corresponding side step surfaces of the sealing sleeve positioning step, and the outer diameter of the sealing sleeve positioning step is smaller than the outer diameter of the insulating sealing sleeve, so that the insulating sealing sleeve can fit tightly with the inner wall of the valve wiring channel and the wiring core is out of contact with the valve wiring channel.

[0006] Furthermore, the aforementioned high-pressure valve channel sealing wiring structure, wherein: two insulating sealing sleeves respectively tightly attached to the step surfaces on both sides of the sealing sleeve positioning step and the sealing sleeve positioning step together form a sealing member positioning groove, the sealing member is arranged in the sealing member positioning groove, and seals the gap between the wiring core and the valve wiring channel.

[0007] Furthermore, in the aforementioned high-pressure valve channel sealing wiring structure, the sealing member is an O-type rubber sealing ring.
