Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-2: the utility model provides a convenient water gauge of equipment, including watchcase 4 and valve gap 3, watchcase 4 and 3 threaded connection of valve gap, valve gap 3 is equipped with counter 1, watchcase 4 is equipped with mounting hole 41, spliced pole 44 and inlet opening 42, spliced pole 44 is equipped with apopore 43, the bottom surface of mounting hole 41 has inclination, inlet opening 42 switches on with mounting hole 41, be equipped with filter screen 8 in the mounting hole 41, filter screen 8 is equipped with guide 7, guide 7 is equipped with rotatable impeller 6, and with the cushion cover 9 of spliced pole 44 laminating.
