Background
The plug-in ultrasonic flowmeter consists of a converter and a pair of plug-in sensors. The plug-in sensor consists of a positioning base, a ball valve and a sensor core. The principle is as follows: when ultrasonic waves pass through liquid, the liquid has a small influence on the insertion time, and the insertion time is changed in proportion to the flow rate of the liquid. The plug-in ultrasonic flowmeter is used for measuring the flow of gas or liquid in a pipeline, but when the plug-in ultrasonic flowmeter is used for measuring the flow of a working medium with more impurities, the impurities are accumulated in a probe after long-time operation, and the plug-in ultrasonic flowmeter is not convenient to disassemble and clean when pressure is applied to the pipeline, so that the measurement performance of the ultrasonic flowmeter is influenced, and the measurement accuracy is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art, provides a cleaning device for an insertion type ultrasonic flowmeter, and solves the problem that a probe of the insertion type ultrasonic flowmeter is inconvenient to clean in work.
In order to achieve the above object, the present invention is achieved by the following technical solutions.
A cleaning device for an insertion type ultrasonic flowmeter is characterized in that the flowmeter is connected with a liquid pipeline through a base, and a flushing interface is arranged on the base; the flushing port of the base is communicated with the liquid pipeline through a flushing pipeline; a filter screen is connected in the flushing pipeline; a booster pump and an electromagnetic valve are arranged on the flushing pipeline; the flowmeter, the electromagnetic valve and the booster pump are respectively connected with the controller.
Furthermore, the flushing pipeline is provided with an outlet check valve, and the outlet check valve is arranged between the electromagnetic valve and the booster pump.
Furthermore, an inlet manual valve is arranged on the flushing pipeline adjacent to the liquid pipeline, and an outlet manual valve is arranged on the flushing pipeline adjacent to the base; the flushing pipeline is connected with a water discharge pipeline, and the water discharge pipeline is positioned between the inlet manual valve and the outlet manual valve.
Furthermore, a manual water discharge valve is arranged on the water discharge pipeline.
Further, the flowmeter is connected with the base through a ball valve.

FIG. 1 is a schematic view of the cleaning apparatus of the present invention.
In the figure, 1 is a ball valve; 2 is a flowmeter; 3 is a base; 4 is an electromagnetic valve; 5 is an outlet hand valve, 6 is an outlet check valve, 7 is a booster pump, 8 is a filter screen, 9 is an inlet hand valve, 10 is a water drain hand valve, 11 is a liquid pipeline, and 12 is a flushing pipeline.
Detailed Description
In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the utility model. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in fig. 1, a cleaning device for an insertion type ultrasonic flow meter includes a base 3; a flushing port is arranged on the base 3; welding a base 3 at a measuring port of a liquid pipeline 11, connecting a ball valve 1 with the base 3 through threads, inserting an inserted ultrasonic flowmeter 2 into the ball valve 1 and the base 3, extending a probe of the flowmeter 2 into the liquid pipeline 11, leading out a flushing water interface from the liquid pipeline 11, and communicating the flushing water interface on the liquid pipeline 11 with a flushing interface of the base 3 through a flushing pipeline 12; an inlet hand valve 9, a filter screen 8, a booster pump 7, an outlet check valve 6, an outlet hand valve 5 and an electromagnetic valve 4 are sequentially connected to the flushing pipeline 12 from one end of the liquid pipeline 11 to one end of the base 3. A drain manual valve 10 is provided between the inlet manual valve 9 and the outlet manual valve 5 for draining water when the booster pump 7 and the inlet strainer 8 are serviced. The flowmeter 2, the electromagnetic valve 4 and the booster pump 7 are respectively connected with a controller. The controller and control program are conventional existing devices and programs.
The specific working process is as follows: when the plug-in ultrasonic flowmeter uploads the measured quality data to the controller, when the measured value is lower than the measurement precision guarantee value, the controller sends an instruction to open the electromagnetic valve 4, the booster pump 7 is automatically started to flush, and when the measured value reaches the measurement precision guarantee value, the booster pump 7 is automatically stopped, and the electromagnetic valve 4 is closed.
When the booster pump 7 is in failure or the filter screen 8 is dirty and needs to be overhauled, the inlet manual valve 9 and the outlet manual valve 5 are closed, and the water discharge manual valve 10 is opened for water discharge. And recovering the original state after the overhaul is finished.
The cleaning device is suitable for cleaning the plug-in ultrasonic flowmeter for measuring more working media of impurities. The problem of measuring the numerical value and appearing the deviation because of the dirty measuring mass that arouses of probe department reduces is avoided, need not to pull down bayonet ultrasonic flowmeter during the washing, can carry out cleaning under operating condition, easily operation.
While the utility model has been described in further detail with reference to specific preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
