Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is for purposes of illustration only and is not intended to limit the scope of the present disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.

As shown in fig. 1 and 2, the water diversion overflow valve for the road roller watering system comprises a valve body 7-1;

the pressure regulating valve is characterized in that a water path interface and an overflow port 7-8 are arranged on the valve body 7-1, an H-shaped water inlet and outlet channel is arranged in the valve body 7-1, a valve core 7-3 is arranged in the overflow port 7-8, a pressure regulating button 7-5 is movably arranged on the valve core 7-3, the pressure regulating button 7-5 is arranged in the valve body 7-1 through threads, the pressure regulating button 7-5 is used for regulating the pressure of a system, and a spring 7-4 is arranged between the valve core 7-3 and the pressure regulating button 7-5.
