Detailed Description
1-5, A coil pilot head assembly with a guide sleeve comprises a coil pilot head assembly 1, wherein the bottom end part of a movable iron core 101 of the coil pilot head assembly 1 is provided with the guide sleeve 2, and the guide sleeve 2 is internally provided with a sealing plug 102 of the coil pilot head assembly 1;
The guide sleeve 2 comprises a shaft extension 201 connected with the inner cavity of the movable iron core 101, an outer circle 203 used for positioning the bottom end surface of the movable iron core 101, a first sliding end 204 and a second sliding end 205 respectively arranged on the bottom end surface of the outer circle 203, and an inner hole 202 used for being connected with the sealing plug 102 arranged inside the shaft extension 201.
The first sliding end 204 and the second sliding end 205 are respectively cylinders.
The outer end surface of the second sliding end 205 is a plane 206.
The first sliding end 204 and the second sliding end 205 are respectively positioned at two sides of the circle center of the guide sleeve 2.
The bottom end surface of the sealing plug 102 is provided with a groove 3.
As can be seen from fig. 5 to 8, in the power-off state of the coil guide head assembly 1, the coil module 104 in the coil 103 of the coil guide head assembly 1 is powered off, the movable iron core 101 is separated from the fixed iron core 106, and a gap is formed between the movable iron core 101 and the fixed iron core 106. Under the action of the conical spring 105, the movable iron core 101 slides in the sliding cavity 6 arranged in the valve seat respectively at the first sliding end 204 and the second sliding end 205, so that the sealing plug 102 presses the boss body 4 of the valve seat of the pneumatic reversing valve, the groove 3 at the bottom end surface of the sealing plug 102 is attached to the boss body 4 to ensure the sealing performance, and the area of the sealing plug 102 is enlarged to ensure that the sealing plug is suitable for sealing high-pressure air inlet channels with different diameters, and can be suitable for the requirements of different oxygenerators. At this time, the high-pressure intake passage 5 in the valve seat is closed; the second sliding end 205 compresses the elastic sealing component 7 in the valve seat, an air inlet gap is formed between the plane 206 of the second sliding end 205 and the sliding cavity 6, and air circulation is facilitated, at this time, the external air passage 8 is opened, air enters the valve body cavity of the pneumatic reversing valve through the external air passage 8, and a part of air is discharged out of the pneumatic reversing valve from the main through hole 9 after passing through the valve body cavity.
