Abstract

The invention relates to a cleanable ultrasonic heat meter flow tube which is provided with a tube body, and an ultrasonic reflecting plane is arranged on the inner wall of the tube body. The cleanable ultrasonic heat meter flow tube has the characteristics that the non-ultrasonic reflecting plane of the tube wall of the tube body is provided with a cleaning hole, and a screwed plug is connected with the cleaning hole through a seal ring. The inner wall of the tube body comprising the ultrasonic reflecting plane can be cleaned conveniently because the non-ultrasonic reflecting plane of the tube wall of the tube body is provided with the cleaning hole, the screwed plug is connected with the cleaning hole through the seal ring, and the screwed plug is demounted, and the technical problem that the scaling of the reflecting plane of the traditional ultrasonic heat meter in the use process affects metering is solved. During cleaning, the heat meter is not necessary to remove and is not necessary to return to the factory for repair. The service life and the year limit of the heat meter are prolonged, and the operation and maintenance costs of the heat meter are reduced. The cleanable ultrasonic heat meter flow tube is especially applicable to the environment which has poor heating water quality and is easy to scale and is applicable to all reflective ultrasonic heat meters of through type flow tubes.

Description

Formula ultrasonic calorimeter flowtube capable of washing

Technical field

The present invention relates to a kind of improvement of ultrasonic calorimeter flowtube, 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.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structurely, be 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 invention, 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 present invention 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 invention;

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 invention will be further described 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 invention 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 II 4, 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 invention, 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.

Claims

1. formula ultrasonic calorimeter flowtube capable of washing, it has body, is provided with the ultrasonic reflections face on inboard wall of tube body, 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.
