Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for processing a venturi tube. Background Art

[0002] Venturi tubes are divided into built-in Venturi tubes and inserted Venturi tubes according to their structures. Good results have been achieved in the measurement of combustion air, cold air, gas (blast furnace gas, coke oven gas, converter gas) of hot blast furnaces in steel plants and large-diameter, low-velocity pipe meters for primary and secondary air of boilers in thermal power plants. It solves the problem of accurate measurement of various types of gas flow at low pressure, large diameter, and low velocity in current industrial enterprises. It is a fluid measurement device with a wide measurement range and easy installation.

[0003] Based on the above, the inventors have found the following problems: Since the apertures at both ends of the venturi tube are different in size and the aperture at the center of the pipe is smaller, a clamp is often used to clamp the two ends of the venturi tube when drilling the hole. However, when clamping the two ends, if the clamping force is large, the two ends of the venturi tube will be squeezed, thereby causing damage to the venturi tube. If the clamping force is small, the venturi tube is prone to loosening during the processing, thereby affecting the accuracy of drilling.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a drilling device for venturi tube processing is provided, in order to achieve the purpose of having more practical value. Utility Model Content
