Abstract
Disclosed is an accurately-metering pipe for a supersonic-wave heat meter. The accurately-metering pipe includes a straight pipe body, reflectors and supersonic-wave sending and receiving devices. The straight pipe body includes an outer pipe and an inner pipe, where the inner pipe is arranged on the inner wall of the middle part of the outer pipe. A pair of reflectors, which are disposed symmetrically and each of which has a mirror face opposite to the mirror face of the other, are arranged in the outer pipe which is outside the two ends of the inner pipe. The reflectors are fixed at two ends of the inner pipe through supports and form inclined angles of 45 degrees with the water-flow direction axis. The supersonic-wave sending and receiving devices capable of receiving supersonic waves sent by each other are arranged respectively in the installation holes, wherein the installation holes are arranged in the outer pipe body which is corresponding to the two reflectors. The accurately-metering pipe for the supersonic-wave heat meter is free from cleaning and maintenance, not liable to be blocked and beneficial for improvement of metering accuracy so that the pipe has the characteristics of being high in metering accuracy, completely free from blockage, insusceptible to any medium and wide in application scope.
Description
Technical field
The utility model relates to a kind of flow measurement device, specifically a kind of ultrasonic heat energy meter accurate measurement pipeline.
Background technology
As everyone knows, owing to cold in winter, for people warm oneself conveniently, safety, heat supply company is transported to every household with hot water by pipeline usually.Use the enthusiasm condition for what measure each household, calorimeter is installed with the heat of using of metering each household at the inlet channel of each household usually, existing calorimeter adopts mechanical type calorimeter and ultrasonic calorimeter usually.At present, the employed flow tube of ultrasonic calorimeter is made of body, flow inlet, water export, transducer mounting hole and temperature sensor mounting hole.The temperature sensor mounting pipe is located at flow of hot water and imports and exports on the body of an end, the reflector plate of its reflection supersonic wave is installed in the inside of pipeline, the deficiency of the flow tube of this structure is: the one, because the reflector plate of reflection supersonic wave is the inside that is fixedly mounted on flow tube, the reflector plate surface can produce dirt in the long-play, can cause measuring error, reflector plate but is not easy to cleaning; The 2nd, reflector plate is installed in the inside of flow tube, when current are out-of-date, can have bubble to produce, if be mixed with bubble in the hot water, will influence the accuracy of measurement result, and then also have influence on the accuracy of metering.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of ultrasonic heat energy meter accurate measurement pipeline, and it not only avoids clean and maintenance, and is difficult for stopping up, and is beneficial to the raising measuring accuracy.
In order to address the above problem, the utility model is by the following technical solutions: a kind of ultrasonic heat energy meter accurate measurement pipeline, comprise straight tube body, catoptron and ultrasonic receiving device, it is characterized in that, described straight tube body comprises outer tube and interior pipe, pipe is arranged on the inwall of outer tube middle part in described, is provided with a pair of symmetry and the relative catoptron of minute surface in the outer tube in the outside, interior pipe two ends, manages two ends and is 45 ° of angles with the current direction axis in described catoptron is fixed on by support; Be respectively arranged with mounting hole at the outer tube body corresponding with two catoptrons, a ultrasonic receiving device is set respectively in the described mounting hole, described two ultrasonic receiving devices can both receive the ultrasound wave of the other side's emission.
Further, described two ultrasonic receiving devices all comprise ultrasonic transmission device and ultrasonic probe, ultrasonic receiver, and the ultrasonic probe, ultrasonic receiver of described two ultrasonic receiving devices receives the ultrasound wave of the other side's ultrasonic transmission device emission respectively.
Further, described ultrasonic receiving device is installed in the mounting hole by gland bonnet.
Further, be provided with O-ring seal between described mounting hole and the ultrasonic receiving device.
Further, pipe two ends in described catoptron is fixed on by four supports.
Further, described flow measurement body also is provided with the temperature sensor mounting interface.
The beneficial effects of the utility model are: compare with the flow measurement straight pipeline of present use, catoptron is fixed by four supports and is 45 ° of angles with the current direction axis, has avoided causing the generation of line clogging phenomenon; In outer tube, in the middle of two catoptrons interior pipe is set, owing to attenuate in the middle of the pipeline, it is urgent suddenly when current flow through, wash away the catoptron eyeglass of back before the urgent current direction, current stream the catoptron eyeglass of the recoil strength impact front of generation simultaneously, thereby avoid catoptron eyeglass surface to produce dirt, avoid clean and maintenance; Attenuate in the middle of making pipeline by pipe in arranging, not only avoided current to produce bubble, and the pipeline current make current be full of pipeline when not enough and current become steady, thereby improve the accuracy of flow measurement.The utility model measuring accuracy height can not stop up fully, is not subjected to the influence of any medium, and is applied widely.
