Embodiment
Below in conjunction with accompanying drawing the utility model level is further described.
As shown in Figure 1, the directly moving piston type electromagnetic valve of the described a kind of heavy caliber of the utility model comprises valve body 1, and valve gap 4 and electromagnetic switch component also are valve body 1, and valve gap 4 and magnetic switch constitute the utility model agent structure.
Form suction port g on the said valve body 1, air outlet a and valve port f, said suction port g is communicated with air outlet a through valve port f.
Said valve gap 4 is located on the valve body 1, forms cavity between said valve gap 4 and the valve body 1, is provided with piston 3 between said valve body 1 and the valve gap 4, and piston 3 is divided into epicoele e and cavity of resorption b with cavity.The corresponding setting with valve port f of said piston 3 is used to control the switch of valve port f, thereby realizes closing air outlet a and being communicated with perhaps of suction port g, and the preferred said piston of the utility model 3 bottoms are provided with seal rubber pad 2.
Form pressure relief vent d on the said piston 3, said pressure relief vent d is communicated with epicoele e and cavity of resorption b, is used for the pressure difference between balance epicoele e and the cavity of resorption b, helps the unlatching of piston 3.
Form pilot hole c on the said valve gap 4, said pilot hole c is communicated with epicoele e and cavity of resorption b, is used for the pressure difference between balance epicoele e and the cavity of resorption b, helps closing of piston 3.The aperture of said pressure relief vent d is greater than the aperture of pilot hole c.
Said electromagnetic switch component is located on the valve gap 4; Said electromagnetic switch component comprises coil carrier 12; Coil carrier 12 is fixedly connected with valve gap 4, and said coil carrier 12 outer periphery have coil 10, is provided with static iron core 11 and moving iron core 9 in coil carrier 12 inner chambers from top to bottom successively; Said moving iron core 9 bottoms are provided with sealing gasket 6, the corresponding setting with pressure relief vent d of said sealing gasket 6.
