Abstract
The utility model relates to a tool for measuring the wall thickness of a pipeline under a pressure, which is convenient for accurately measuring the wall thickness parameters of a measured pipeline, is suitable for metering the liquid flow and heat numerical value in a pipeline by using an inserted ultrasonic flow meter, and belongs to flow metering. According to the technical scheme of the utility model, the tool comprises a ball valve (2), a connecting nut (3), a guide sleeve (4), a measuring rod (5) and a sealing gasket (7), wherein the guide sleeve is connected with the ball valve through the connecting nut; the measuring rod passes through the guide sleeve; and the end part of the measuring rod is provided with a measuring card (6). The tool has the beneficial effects that the tool has the characteristics of simple and reasonable structure, convenience for using, accurate measurement and the like, can be widely applied to various occasions on which the wall thicknesses of pipelines are required to be measured accurately, and is particularly suitable for the occasion of measurement of the liquid flow in a pipeline by using an inserted ultrasonic flow meter; and the defects of the prior art are overcome.
Description
Technical field
The utility model relates to a kind of band and presses measuring channel wall thickness instrument, is convenient to accurately measure tested pipeline wall thickness parameter, is applicable to utilize fluid flow, heat numerical value in the plug-in type ultrasonic flowmeter metering pipeline, belongs to flow metering.
Background technology
At present, during fluid flow, pipeline wall thickness is a very important parameter to domestic existing plug-in type ultrasonic flowmeter, directly influences the measuring accuracy of flowmeter in the metering pipeline.The method of background technology measuring channel wall thickness mainly is to block duct survey through cutting off the water or according to the circuit design data check.But, do not allow to cut off the water or circuit design data when losing for some pipelines, can only confirm the thickness of duct wall through the way of estimation, the pipeline wall thickness parameter can not accurately be provided, thereby influence the measurement accuracy of flowmeter.
The utility model content
The utility model purpose provides a kind of band and presses measuring channel wall thickness instrument, for the plug-in type ultrasonic flowmeter provides reliably, accurate wall thickness parameter, solves the problems referred to above that exist in the background technology.
The technical scheme of the utility model is:
A kind of band is pressed measuring channel wall thickness instrument, comprises ball valve, attaching nut, guide pin bushing, sealing gasket and sounding rod, and guide pin bushing is connected with ball valve through the attaching nut, and sounding rod passes in guide pin bushing, and the end of sounding rod is provided with measures card.
The both side ends of guide pin bushing is provided with sealing gasket, and sounding rod passes sealing gasket and gets into guide pin bushing, and stretches out the guide pin bushing bottom, passes ball valve.
The maximal projection diameter of sounding rod and measurement card less than the internal diameter of guide pin bushing and ball valve, is convenient to measure card and is got in the pipeline.Said measurement card is L shaped structure, the sounding rod end bent; Said measurement card can also be T shape structure, and the sounding rod end is provided with the measurement sword that stretches out at two ends.
Attaching nut's shape is arbitrarily, and guide pin bushing and sounding rod can be two independently parts, also can be one, and its shape is arbitrarily.
When adopting the utility model to carry out wall thickness measuring, at first utilize special-purpose drilling tool (like the pipe pressurized boring bar tool ZL99202114.6 of hand-held of my application) perforate on pipeline, and mounting ball valve, close ball valve then.When the attaching nut guide pin bushing is connected with ball valve finish after, open ball valve, sounding rod is inserted in the pipeline and the wheel measuring bar, make it measure card and expose, be stuck on the inner-walls of duct, upwards strain sounding rod then and make and measure card and contact with inner-walls of duct; Through between measuring tube outer wall and the sounding rod apart from B and known sounding rod length overall A, promptly know tested pipeline wall thickness t=A-B.
The beneficial effect of the utility model: the utlity model has characteristics such as simple and reasonable, easy to use, that measurement is accurate; Overcome the shortcoming of prior art; The various occasions that can widespread use need accurate measuring channel wall thickness are particularly useful for the occasion of fluid flow in the plug-in type ultrasonic flowmeter measuring channel.
