Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] As shown in the figure, an overload protection valve includes a valve sleeve 1, a valve core 2, a valve sleeve seat 3, a pressure regulating screw 4, a pressure regulating valve seat 5, and a lock nut 6. In order to improve the sealing performance of the overload valve, A sealing ring 7 is provided outside the valve sleeve 1 , a sealing ring 10 is provided outside the valve sleeve seat 3 , and a sealing ring 12 is provided outside the pressure regulating valve seat 5 . The valve sleeve seat 3 is connected to the rear end of the valve sleeve 1. In order to improve the processing speed and processing accuracy of the two, the valve sleeve 1 and the valve sleeve seat 3 are processed separately, and the rear end of the valve sleeve 1 and the front end of the valve sleeve seat 3 are made of Snap connection. The front end of the pressure regulating valve seat 5 is pro...
