In the prior art, two separate bushings are inlaid on the moving iron core, and there is no bushing in the static iron core. Since the operating frequency of the solenoid valve core is 580-700 times per minute, the head end of the moving iron core will be small after a period of use. Bushings will naturally wear

Embodiment Construction
[0011] The present invention will be further described below in conjunction with specific embodiments.
[0012] Such as Figure 1 to Figure 3 As shown, a solenoid valve core capable of reducing wear includes a static iron core 1 and a movable iron core 2 that are matched with each other. The static iron core 1 includes a first iron core section 102, a second iron core section 105 and The third iron core section 106, the first iron core section 102, the second iron core section 105 and the third iron core section 106 are integrally formed, the first iron core section 102 is a thin-walled section, and the third iron core section 106 is Thick-walled section, the first iron core section 102 and the third iron core section 106 are made of soft magnetic material, and the second iron core section 105 is made of non-magnetic material. There is a placement slot 108 in 102, and the movable iron core 2 is movably arranged in In the placement groove 108, the surface of the third core sectio...

The invention discloses a magnetic valve core capable of reducing wear and belongs to the field of textile machinery accessories. The magnetic valve core capable of reducing wear comprises an unmovable iron core and a movable iron core matched with each other, wherein the movable iron core comprises a main body, a first connection rod and a second connection rod which are integrally designed, the axes of the main body, the first connection rod and the second connection rod are all on a same line, and the diameters of the main body, the first connection rod and the second connection rod decrease progressively in sequence; one end, connected with the main body, of the first connection rod, is sleeved with a sealing O-shaped ring; an air outlet groove is formed in the movable iron core; the air outlet groove penetrates through the second connection rod and stops in the first connection rod; rectangular locating grooves are also formed in the surfaces of the first connection rod and the second connection rod. According to the magnetic valve core capable of reducing wear, the friction wear of the movable iron core is reduced effectively, the service life of the movable iron core is prolonged, and the changing frequency of the movable iron core is reduced.
Description
technical field [0001] The invention belongs to the field of textile machinery accessories, and more specifically relates to a solenoid valve core capable of reducing wear. Background technique [0002] The solenoid valve is an important electrical component on the air-jet loom to control the weft insertion airflow and the length of the air injection time. When the loom is in operation, the main spray, auxiliary spray, and weft suction solenoid valves are required to operate according to the preset time frequency. The opening and closing action is jetted, and the compressed air passes the weft yarn from left to right through the upper and lower warp yarns, and interweaves to form a cloth. In the prior art, the moving iron core is inlaid with two separate bushings, and there is no bushing in the static iron core. Since the operating frequency of the solenoid valve core is 580-700 times per minute, the head end of the moving iron core is small after a period of use. Bushings ...
