近年来,高压湿式电磁铁的电磁换向阀(以下简称湿式电磁换向阀)在国外已受到广泛的重视,产品的规格和品种也有了迅速的发展。所谓湿式电磁铁,就是换向阀两端O腔的回油能进入电磁铁内部;电磁铁的衔铁浸在油中工作;电磁铁与换向阀结合面的密封靠阀体两端O形密封圈来实现。它与干式电磁换向阀比较,有以下优点:(1)由于进入电磁铁的油液产生阻尼作用,使滑阀换向和复位动作平稳,可减小液压冲击。(2)进入电磁铁内的油液带走了电磁铁工作时产生的热量,延长了电磁铁的使用寿命。(3)由于取消了O形圈座的结构,因此,解决了
In recent years, high pressure wet electromagnet electromagnetic reversing valve (hereinafter referred to as wet electromagnetic reversing valve) in foreign countries has received widespread attention, product specifications and varieties have also been rapid development. The so-called wet-type electromagnet, is the reversing valve at both ends of the O cavity of the return oil can enter the interior of the electromagnet; electromagnet armature immersed in the oil work; electromagnet and reversing valve with the sealing surface by the valve body at both ends of the O-ring seal Circle to achieve. Compared with the dry solenoid valve, it has the following advantages: (1) Due to the damping effect of the oil entering the electromagnet, the slide valve can be reversed and reset smoothly to reduce the hydraulic impact. (2) The oil entering the electromagnet takes away the heat generated when the electromagnet works, which prolongs the service life of the electromagnet. (3) Since the structure of the O-ring seat was canceled, it was solved
