The flow sensor of ultrasonic calorimeter
Technical field
The present invention relates to a kind of ultrasonic calorimeter, specifically is the flow sensor of ultrasonic calorimeter.
Background technology
The structure of the flow sensor of ultrasonic calorimeter generally comprises body, first ultrasonic transducer, second ultrasonic transducer, first reflecting plate and second reflecting plate; First ultrasonic transducer and second ultrasonic transducer are located at a side of body; First reflecting plate and second reflecting plate are located at the opposite side of body respectively accordingly with first ultrasonic transducer and second ultrasonic transducer, and first reflecting plate and the corresponding setting of the reflecting slant of second reflecting plate.The import that present China is using in heat supply market or the flow sensor of homemade ultrasonic calorimeter; Its reflecting plate fixedly mainly contain two kinds of forms; A kind of is that whole plastic supporting pieces is set in body, and first reflecting plate and second reflecting plate are fixed on the relevant position of plastic supporting pieces; Another kind is that the position corresponding to first reflecting plate and second reflecting plate is respectively arranged with plastic supporting pieces in body, and first reflecting plate and second reflecting plate are individually fixed on this plastic supporting pieces.The flow sensor of existing these two kinds of ultrasonic calorimeters; Because its reflecting plate is whole to be fixedly mounted in the body, reflecting plate can not onlinely be dismantled, and can't flow sensor carry out Hand scarf, maintenance; If heat supply pipeline cleans thoroughly or in the heating water quality during the more situation of impurity; Reflecting plate or ultrasonic transducer end face can adhere to incrustation scale or other foreign material, along with the calorimeter increase of service time, and reflecting plate or the meeting fouling of ultrasonic transducer surface; The problems referred to above can have influence on the collection of flow signal, thus the accuracy of influence metering.And, being installed in the plastic supporting pieces in the body, long-term work is prone to aged deterioration in hot environment, cause the serviceable life of flow sensor shorter.
Summary of the invention
But the purpose of this invention is to provide a kind of Hand scarf, maintenance, and serviceable life is than the flow sensor of long ultrasonic calorimeter.
Technical scheme of the present invention is such: the flow sensor of ultrasonic calorimeter; Comprise metal body, first ultrasonic transducer, second ultrasonic transducer, first reflecting plate and second reflecting plate; First ultrasonic transducer and second ultrasonic transducer are located at a side of metal body; First reflecting plate and second reflecting plate are located at the opposite side of metal body respectively accordingly with first ultrasonic transducer and second ultrasonic transducer, and first reflecting plate and the corresponding setting of the reflecting slant of second reflecting plate; Above-mentioned first reflecting plate and second reflecting plate comprise respectively by integrated reflecting plate body of metal material and installing plate; Offer respectively the corresponding mounting hole of reflecting plate body on the above-mentioned metal body with above-mentioned first reflecting plate and second reflecting plate; The reflecting plate body of above-mentioned first reflecting plate and second reflecting plate is stretched in the above-mentioned metal body by above-mentioned mounting hole respectively, and above-mentioned installing plate is movably installed in the lateral surface of above-mentioned metal body respectively.
Above-mentioned installing plate locks on above-mentioned metal body through bolt respectively.
Be provided with O-ring seal between above-mentioned installing plate and the above-mentioned mounting hole.
Above-mentioned installing plate is covered with gland outward.
After adopting such scheme, the flow sensor of ultrasonic calorimeter of the present invention has following beneficial effect: whole flow sensor does not have any plastic components, and improve serviceable life greatly; Because the installing plate of reflecting plate is movably arranged on the lateral surface of metal body; In the calorimeter use, but reflecting plate on-line replacing or thoroughly cleaning needn't be dismantled calorimeter; Needn't depot repair; Improve administrative authority's efficient, reduced the maintenance cost of administrative authority, the influence that the user causes is dropped to minimum to the daily servicing of calorimeter.
