AI Technical Summary
The sealing regulating valve of the existing door closer is prone to tilting of the fixed seat and lateral deviation of the valve disc under the long-term flushing of hydraulic oil, resulting in reduced sealing effect and accelerated wear.
The overlap block drives the end rod to move the pressure block downward to reinforce the edge of the fixed seat, and the elastic part drives the positioning block to enhance the lateral support force of the valve disc. The sealing material and the shaft sleeve are combined to reduce friction and improve the sealing effect.
It effectively prevents the fixed seat from tilting and the valve disc from lateral deviation, prolonging the service life and improving the sealing performance.
