Abstract
The utility model relates to a cleanable flow tube for ultrasonic heat meter, which is provided with a tube body. An ultrasonic wave reflecting surface is arranged on the inner wall of the tube body. The flow tube is characterized in that a cleaning hole is formed on the tube wall of the non-ultrasonic reflecting surface of the tube body; and a screw plug is connected with the cleaning hole through a sealing ring. Due to the adoption of the structure that the cleaning hole is formed on the tube wall of the non-ultrasonic reflecting surface of the tube body, and the screw plug is connected with the cleaning hole through the sealing ring, the screw plug is disassembled, and the inner wall of the tube body including the ultrasonic wave reflecting surface can be cleaned by using a cleaning tool. The flow tube solves the technical problem that the measurement is affected by the scale formation of the reflecting surface during the use of the existing ultrasonic wave heat meter; the heat meter is not required to be disassembled during the clearing process or to be repaired at the original factory, so that the service life and the age limit of the heat meter are improved, and the operation and maintenance cost is reduced. The cleanable flow tube is particularly suitable for the environment where the quality of supplied hot water is poor, and the scale formation is easy and is applicable to reflecting type ultrasonic wave heat meters of all through type flow tubes.
Description
Technical field
The utility model relates to a kind of improvement of ultrasonic calorimeter flowtube, and specifically a kind of formula ultrasonic calorimeter flowtube capable of washing belongs to the flow detector technical field.
Background technology
At present, the measuring ultrasonic wave flow technology is used on the calorimeter and reaches its maturity, wherein more general with reflective application especially, generally comprise flowtube, ultrasound reflector, ultrasonic transmission device, measuring apparatus formation, wherein, ultrasound reflector mainly contains two kinds, and a kind of is that catoptron is installed in flowtube, utilizes catoptron to come reflection supersonic wave; A kind of is to utilize the flowtube inwall to reflect.Because carrying out heat conducting in the flowtube is water, contain dust and impurity in the water, and ultrasound reflector is the inwall of flowtube or places the interior catoptron of flowtube, dust in the water and impurity easy to hang in flowtube inwall or catoptron on and fouling, and working time, long more fouling was thick more, influenced hyperacoustic reflection and caused measuring and inaccurately maybe can't measure; Though it is removable that catoptron is arranged now, when needing catoptron pulled down and clean, catoptron dismounting complexity, the erecting stage operating difficulties, and on-the-spot dismounting catoptron also can exert an influence to the measuring accuracy of product, also needs detect again product.
The utility model content
The purpose of this utility model provides a kind of simple in structure, is convenient to the online formula ultrasonic calorimeter flowtube capable of washing that the flowtube inwall of ultrasonic calorimeter is cleaned.
The technical scheme that is adopted is for achieving the above object: a kind of formula ultrasonic calorimeter flowtube capable of washing, it has body, on inboard wall of tube body, be provided with the ultrasonic reflections face, it is characterized in that: be provided with clean-out opening on the tube wall of the non-ultrasonic reflections face of body, plug is connected with clean-out opening by O-ring seal.
Formula ultrasonic calorimeter flowtube capable of washing of the present utility model, owing to adopt and on the tube wall of the non-ultrasonic reflections face of body, be provided with clean-out opening, the structure that plug is connected with clean-out opening by O-ring seal, the dismounting plug, use cleaning tool just can easily the inboard wall of tube body that comprise the ultrasonic reflections face to be cleaned, solved the technical matters of reflecting surface scale effect metering in the existing ultrasonic calorimeter use, can when filter rinsed, clean the inboard wall of tube body that comprises the ultrasonic reflections face in the lump, also can clean the inboard wall of tube body that comprises the ultrasonic reflections face separately, needn't pull down calorimeter, needn't return the repair in shop reason, the serviceable life and the time limit of calorimeter have been improved, reduced the operation expense of calorimeter, be particularly suitable for the heat supply water quality inferiority, easily the environment of fouling uses.The utility model is applicable to the reflecting type ultrasonic calorimeter of all through flowtube.
Description of drawings
Fig. 1 looks synoptic diagram for master of the present utility model;
Fig. 2 is a B-B cross-sectional schematic among Fig. 1;
Fig. 3 is an A-A diagrammatic cross-section among Fig. 1.
Among the figure: 1 water inlet threaded connector, 2 ultrasonic transducer mounting hole I, 3 pairing temperature sensor mounting holes, 4 ultrasonic transducer mounting hole II, 5 water outlet threaded connectors, 6 plugs, 7 O-ring seals, 8 ultrasonic reflections faces.
Embodiment
The utility model is described in further detail to utilize specific embodiment shown in the drawings below.
With reference to Fig. 1-3, formula ultrasonic calorimeter flowtube capable of washing of the present utility model comprises water inlet threaded connector 1, the water outlet threaded connector 5 that is provided with on the body, ultrasonic transducer mounting hole I 2, ultrasonic transducer mounting hole II4, pairing temperature sensor mounting hole 3, on inboard wall of tube body, be provided with ultrasonic reflections face 8, be provided with clean-out opening on the tube wall of the non-ultrasonic reflections face of body, plug 6 is connected with clean-out opening by O-ring seal 7.The clean-out opening of this specific embodiment is two and opposite disposed, also can be provided with one or more as required.
In the time of need cleaning the ultrasonic reflections face 8 of formula ultrasonic calorimeter flowtube capable of washing of the present utility model, plug 6 is unloaded, with cleaning tool the inboard wall of tube body that comprises ultrasonic reflections face 8 is cleaned, after cleaning is finished the plug 6 that unloads is connected with clean-out opening by O-ring seal 7, calorimeter can recover operate as normal again.The flowtube body is generally cast type with aldary forging and pressing or essence.When plug 6 aldary machine-shaping, plug 6 were connected with clean-out opening, the inner face of plug 6 stretched in the body, concordant with inboard wall of tube body.
