Specific implementation mode
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment：
It please refers to shown in Fig. 1, a kind of Converter Station Valve cooling system blower fan of cooling tower belt tightness degree detector, including vertical bar
1, upper detection pawl 2, lower detection pawl 3, pressure measuring instrument 4, long bolt 5 and rotating handles 6.
Wherein, vertical bar 1, upper detection pawl 2 and lower detection pawl 3 constitute " F " shape main body, and upper detection pawl 2 is fixed on vertically
1 upper end of bar, lower detection pawl 3 are slidably arranged in the underface of lower detection pawl, and " F " shape main body is by light rigid materials (such as aluminium alloy)
It is made, precision is carved in vertical bar 1 to the scale of millimeter, upper 2 lower face of detection pawl is 0 point of scale, and lower 3 side of detection pawl is carved
