Abstract
The utility model relates to the technical field of valve bodies, in particular to a one-way throttle valve. The one-way throttle valve comprises a valve body, wherein a valve core seat is arranged on the valve body, an air inlet, a valve cavity and an air outlet are formed in the valve body, and a valve core cavity is formed in the valve core seat. The valve core cavity is communicated with the valve cavity through a valve opening, the air inlet is communicated with the valve core cavity through an upper flow channel, and a valve core which can move up and down is arranged in the valve core cavity. The bottom portion of the valve core corresponding to the valve opening is arranged, a screw rod is fixedly connected with the valve core, and the upper end of the screw rod penetrates through a screw hole of the valve core seat and is connected with a nut. A rear cover nut is arranged at the bottom of the valve cavity, the air inlet is communicated with the valve cavity through a lower flow channel, and a sealing seat is correspondingly arranged on the lower flow channel. Compressed springs are arranged on the sealing seat and the rear cover nut. The upper flow channel and the lower flow channel are arranged, and when the one-way throttle valve is started up, air flows into the upper flow channel and the lower flow channel, and kinematic velocity of an actuator element is effectively met.
