SPRING ADJUSTING DEVICE AND VALVE ASSEMBLY

摘要

Disclosed is a spring adjusting device, comprising an adjusting screw (310), a spring (320) and a spring seat (330) located between the adjusting screw (310) and the spring (320), wherein the spring seat (330) is provided with a groove (333) capable of accommodating a tip portion of one end of the adjusting screw (310), the groove (333) being provided with a cylindrical side wall. Further disclosed is a valve assembly containing this spring adjusting device. The spring adjusting device can prevent the screw tip portion from disengaging from the groove and can avoid the overall bending of the spring, so that the operating performance of the overall valve assembly can be improved.
