Description

TECHNICAL FIELD

[0001] The present application relates to a kind of instruments for measuring the nozzle angle of industrial spray pipeline, belong to industrial spray pipeline measuring instrument field. BACKGROUND

[0002] In the metallurgical and chemical industry, fluid medium such as oil, water, air is often sprayed to the surface of industrial products through pipeline accessories such as nozzles, to play the role of cooling, lubrication or changing product characteristics. The commonly used structure of industrial spray pipeline currently includes a spray beam and a nozzle, and the nozzle is installed on the spray beam according to the process design requirements.

[0003] In actual use, when the spray beam structure is installed on the production line, the spray angle of the spray beam structure acting on the industrial products often deviates from the design and use requirements due to the influence of factors such as narrow space, visual obstruction, and poor on-site environment, which adversely affects the cooling, lubrication or characteristic change of the products, and additional medium needs to be consumed or additional processes need to be added to make up for it. In addition, when the on-site process personnel track and debug the nozzle spray angle, the nozzle spray angle also needs to be measured frequently. Therefore, the adjustment and verification of the nozzle spray angle of the spray beam structure is very important.

[0004] The common method for measuring the spray angle of the installed spray beam is not accurate enough, has high requirements for the on-site environment, and the measured data often does not meet the accuracy requirements. The currently used high-precision measuring instruments such as laser measuring instruments have high prices, complex operation steps when measuring the angle, are not convenient to carry, require flat and stable equipment placement positions, are greatly affected by factors such as narrow nozzle installation space and visual obstruction, need to be stopped for a long time, which brings great inconvenience to the measurement of the nozzle angle after the installation of the spray beam; the method of installing a spray beam angle indicating disc outside the equipment rack can also be used, but the working site environment is poor, the equipment and pipelines are full of acid, alkali, water, dust and other media, which can easily make the scale disc blurred and corroded, and the manufacturing and installation accuracy of the pipelines and nozzles will also affect the accuracy of the measured spray angle. If the nozzle spray angle is not installed according to the design requirements, it will seriously affect the spraying effect of acid, alkali, water, oil and other media, reduce the surface quality and quality grade of the products, increase the amount of medium, and increase the cost and maintenance difficulty of the pipeline and nozzle parts. This situation has not been improved so far and needs to be solved by technical personnel. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a nozzle angle measuring instrument for industrial spray pipeline, which has compact structure, is convenient to carry and use, has high measurement accuracy, can quickly and accurately measure the spray angle of the nozzle of the spray beam in the industrial production line, reduces the measurement time and difficulty, improves the accuracy and work efficiency of the measurement, reduces the use cost, and ensures the continuous and stable work of the nozzle.

The thin wall frame and the circular ring frame are an integral structure. The semicircular groove is arranged between the thin wall frame and the circular ring frame. The circumference middle part of the thin wall frame is provided with a pointer insertion hole.
