Abstract
The invention discloses a V-shaped flow tube for an ultrasonic heat meter, which comprises a tube body. A water inlet, a water outlet and paired temperature sensor mounting holes are formed on the tube body. The V-shaped flow tube is characterized in that: a V-shaped tube is arranged on the tube body between the water inlet and the water outlet; the two upper orifices of the V-shaped tube are ultrasonic transducer mounting holes I and II; a bottom orifice of the V-shaped tube is in sealing connection with an ultrasonic reflecting pipe plug; and the point of intersection of two center lines of the V-shaped tube is formed on the reflecting surface of the ultrasonic reflecting pipe plug. The V-shaped flow tube solves the problem that the conventional heat meter can ensure the measurement accuracy only by a complex variable diameter structure, reduces the influence of attenuation of repeated refraction of ultrasonic waves on the measurement accuracy to achieve high measurement accuracy and low pressure loss by adopting the structure of reducing the reflection times of the ultrasonic waves, also can conveniently online clean the reflecting surface and the inner wall of the tube body without disassembling the heat meter and returning the heat meter to a factory for repair so as to prolong the service life of the heat meter and reduce the running and maintenance cost of the heat meter, and is particularly suitable for environments with hot water which is low in quality and easy to scale.
Description
Technical field
The present invention relates to the flow measurement device technical field, is a kind of ultrasonic calorimeter V-type flowtube.
Background technology
At present, the measuring ultrasonic wave flow technology is used on the calorimeter very ripe, wherein more general with reflective application especially, generally comprising flowtube, catoptron (comprise and utilize flowtube itself to reflect), ultrasonic transmission device and measuring apparatus constitutes, wherein, the reflection mode 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 inboard wall of tube body to reflect, and does not have the catoptron of installing in addition in the flowtube body.No matter adopt which kind of mode, all be to adopt the mode of measuring section necking down to solve basically in order to guarantee measuring accuracy owing to be subjected to showing the restriction of body self length; Calorimeter all can fouling on catoptron or flowtube inboard wall of tube body after reality is used a period of time in addition, and working time, long more fouling was thick more, finally causes measuring inaccurately maybe can't measuring; Though it is removable that catoptron is arranged now, when needing catoptron pulled down and clean, catoptron dismounting complexity, on-the-spot fitting operation difficulty, 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 objective of the invention is at the deficiencies in the prior art, provide a kind of rational in infrastructure, the ultrasonic reflections number of times is few, the measuring accuracy height, and the pressure loss is little, and can realize the flowtube on-line cleaning, cleans ultrasonic calorimeter V-type flowtube easily.
Realize that the technical scheme that above-mentioned purpose is taked is:
A kind of ultrasonic calorimeter V-type flowtube, it comprises body, on body, be provided with entery and delivery port and pairing temperature sensor mounting hole, it is characterized in that: on the body between the entery and delivery port, be provided with v-shaped tube, two upper port of described v-shaped tube are respectively ultrasonic transducer mounting hole I and ultrasonic transducer mounting hole II, and the bottom nozzle of described v-shaped tube and ultrasonic reflections plug are tightly connected.
The intersection point of two center lines of described v-shaped tube is on the reflecting surface of ultrasonic reflections plug.
Ultrasonic calorimeter of the present invention V-type flowtube, owing to be positioned at into, body between the water delivering orifice is provided with v-shaped tube, two upper port of described v-shaped tube are respectively ultrasonic transducer mounting hole I and II, the bottom nozzle of described v-shaped tube and ultrasonic reflections plug are tightly connected, solved existing ultrasonic calorimeter could guarantee measuring accuracy by complicated variable-diameter structure problem, compare with other reflection mode simultaneously, owing to adopt the structure that reduces the ultrasonic reflections number of times, the decay that the minimizing ultrasound wave reflects repeatedly is to the influence of measuring accuracy, its measuring accuracy height, the pressure loss is little; Can also conveniently unload the ultrasonic reflections plug inwall of reflecting surface and body is carried out on-line cleaning, needn't pull down calorimeter, needn't return the repair in shop reason, improved the serviceable life of calorimeter, reduced the operation expense of calorimeter, be particularly suitable for the heat supply water quality inferiority, easily the environment of fouling uses.
