The invention provides a pilot-operated type high-pressure self-locking valve. The pilot-operated type high-pressure self-locking valve comprises a main valve and a pilot valve, the pilot valve is installed on the main valve, an inlet of the pilot valve is communicated with a main valve element (6) of the main valve, and an outlet of the pilot valve is communicated with an outlet channel of the main valve. The stress state of the main valve element (6) is changed by changing the pressure of the rear end of the main valve element (6), and opening and closing of the main valve element (6) are controlled. The pilot-operated type high-pressure self-locking valve is high in working pressure, high in response speed and capable of being started repeatedly.
本发明公开了一种先导式高压自锁阀,所述先导式高压自锁阀包括主阀和先导阀,所述先导阀安装至所述主阀上并设置为所述先导阀的入口与所述主阀的主阀芯(6)相通,所述先导阀的出口与所述主阀的出口通道相通,通过改变主阀芯(6)后端的压力以改变主阀芯(6)的受力状态,控制主阀芯(6)的开启与关闭。该先导式高压自锁阀的工作压力高、响应速度快,并且,可以重复启动。
