Description
(1) technical field
The utility model relates to the flow measurement field, and relating to a kind of ultrasonic reflections sheet specifically can pinpoint structural member.
(2) background technology
The flow rate of fluid measurement that ultrasound wave is used for pipeline section has many advantages.Compare its measuring accuracy height with traditional mechanical flow instrument electromagnetic flow instrument, strong to the adaptability of caliber, the noncontact fluid, easy to use, be easy to digital management or the like.Current, the ultrasound wave instrument of most of manufacturer production all is to utilize the ultrasound wave mistiming that following current propagation and adverse current are propagated in fluid this principle that is directly proportional with rate of flow of fluid to measure fluid flow.In the actual application of utilizing the ultrasonic flow measurement amount, the angle of two reflector plates and correct position are whether, whether the correct position of two reflector plates and two transducers directly have influence on the precision of ultrasonic measurement fluid flow.As shown in Figure 1: ultrasonic transducer A ultrasonic waves transmitted is the following current time through reflector plate D to ultrasonic transducer B through reflector plate C again; Otherwise, ultrasonic transducer B ultrasonic waves transmitted is the adverse current time through reflector plate C to ultrasonic transducer A through reflector plate D again, therefore, the position of the angle of two reflector plates and position, two two reflector plates and two transducers must be accomplished: ultrasonic reflections sheet C and surface level angle at 45, ultrasonic reflections sheet D and surface level angle at 45; Ultrasonic reflections sheet C and ultrasonic reflections sheet D need point-blank and the position corresponding; Ultrasonic transducer A and ultrasonic reflections sheet C need point-blank and the position correspondence; Ultrasonic transducer B and ultrasonic reflections sheet D need point-blank and the position corresponding.This kind requirement is structurally complicated, is not easy to produce in batches on technology, and a kind of ultrasonic reflections sheet of my company's utility model patent can solve above problem by pinpoint structural member for this reason, and is simple in structure, and the location is easy to mass production easily.
(3) utility model content
The purpose of this utility model is the deficiency that is difficult for location, positioning device structure complexity at ultrasound wave ultrasonic reflections sheet when measuring the pipeline section fluid flow, and the ultrasonic reflections sheet that provide a kind of location simple in structure, easy, is easy to mass production can pinpoint structural member.
The utility model is the technical scheme that its technical barrier of solution is taked:
A kind of ultrasonic reflections sheet can pinpoint structural member, contains two ultrasonic reflections sheet positioning tables, a structural member pilot hole.It is characterized in that: described structural member is an one; Described structural member inside is hollow cavity; Fluid is from two ultrasonic reflections sheet positioning table intermediate flow mistakes, and promptly the end from the hollow cavity of structural member flows to the other end; Angle between described two ultrasonic reflections sheet positioning tables and the surface level is 45 °, and two ultrasonic reflections sheet positioning tables point-blank and the position correspondence; Described structural member pilot hole is connected through screw with the caliber pilot hole that is complementary with it, and this structural member is fixed, thus make two ultrasonic transducers respectively with two ultrasonic reflections sheets point-blank and the position corresponding.
A kind of ultrasonic reflections sheet of the utility model can pinpoint structural member assembly method: during assembling, the external diameter of structural member must be consistent with the internal diameter of pipeline section, structural member is gone into from an end plug of pipeline section, when the structural member pilot hole is corresponding with the caliber pilot hole, with screw two holes are connected, structural member is fixed, thus guaranteed two ultrasonic transducers respectively with two ultrasonic reflections sheets point-blank and the position corresponding.Because the angle between two ultrasonic reflections sheet positioning tables and the surface level is 45 °, guaranteed that therefore the angle between two ultrasonic reflections sheets and the surface level also is 45 °; Two ultrasonic reflections sheet positioning tables and the position correspondence have guaranteed that two ultrasonic reflections sheets also and the position correspondence point-blank point-blank.
The beneficial effects of the utility model are:
(1) a kind of ultrasonic reflections sheet of the utility model can pinpoint structural member have improved the degree of accuracy of ultrasonic measurement fluid flow greatly.
(2) a kind of ultrasonic reflections sheet of the utility model is can pinpoint structural member simple in structure, is easy to mass production.
When (3) a kind of ultrasonic reflections sheet of the utility model can pinpoint structural member have thoroughly solved existing ultrasonic measurement pipeline section fluid flow owing to reflector plate position, the coarse problem of the incorrect measurement that causes of transducer position.
