Description
Technical field
The utility model relates to ultrasonic transducer changing device more online, can be used to the ultrasonic transducer that ultrasonic flowmeter do not shut down ultrasonic flowmeter and carry out on-bne repair, maintenance and replacing under work condition state.
Background technology
At present, ultrasonic flowmeter becomes the first-selected instrument of gas dosing gradually.But, main and the most flimsy parts as it, ultrasonic transducer overhauls at the scene, safeguards and when changing, and is just very difficult if do not carry out stopping the supple of gas or steam in pipeline, even can't carry out; Especially in, in bigbore flow measurement.Existing a kind of changing device more online, its leading screw supporting structure is a tubbiness shape of standing upside down, inner circle at the lower part outlet of handstand tubbiness, the connection internal thread that the long left and right of one 10mm is arranged, in order to the ultrasonic transducer fixture on joint carry out thread connection, with fixing leading screw support, and then fixing online the replacing changes device; The top center of handstand tubbiness has a long internal thread of 10mm to support through hole, and in order to supporting the dismounting leading screw, and it is reciprocating to allow it be loaded with the activity adjustment bar, with for convenience detach and fill again ultrasonic transducer; The top of handstand tubbiness and bucket wall are solid construction.Therefore one, structure are very heavy, the dismounting difficulty needs to use the specific purpose tools such as large torque wrench; Its two, because surrounding bucket wall is solid, thus when ultrasonic transducer by dismounting leading screw guiding, when being withdrawn into the bowl inner chamber of leading screw support with the activity adjustment bar, the staving that still is closed in the leading screw support is inner, can't carry out any processing to ultrasonic transducer; Its three, be with whole changing device more online, and the activity adjustment bar that is loaded with ultrasonic transducer all disassembles fully connecting the internal thread place, could carry out every technical finesse to ultrasonic transducer; After complete, then secondary installing changing device more online, ultrasonic transducer is carried out multiple dress; This operating process bothers very much, wastes time and energy; And due to twice installation before and after more changing device itself just has online, cause online more changing device to have the deviation of concentricity and the deviation of upper-lower position, thereby cause the path of ultrasonic propagation and direction to change, and then the accuracy of ultrasonic flowmeter is had certain impact.
Summary of the invention
For the shortcoming that prior art exists, it is a kind of simple in structure that the utility model provides, and volume is light and handy, can directly overhaul, safeguard, change and answer the ultrasonic transducer that fills changing device more online on ultrasonic transducer.
Ultrasonic transducer is changing device more online, it is characterized in that, and by leading screw, dicyclo hollow leading screw support, handle forms, and handle and leading screw are affixed;
Described dicyclo hollow leading screw support is comprised of by the affixed upper apical ring of brace rod lower base ring;
The inner circle of lower base ring is through hole whorl, and the length of its through hole whorl equates with the thickness of lower base ring; The interior fenestra of upper apical ring is through hole whorl, and the length of its through hole whorl equates with the thickness of upper apical ring;
Connector internal thread on the internal thread of lower base ring and ultrasonic transducer fixture is connected and fixed;
Upper apical ring is connected with the internal thread of leading screw, and the external screw thread of the bottom of leading screw internal thread and activity adjustment bar is connected and fixed; Be slidably connected by inner seal ring between the activity adjustment bar of ultrasonic transducer fixture and upper binding head.
The upper binding head of lower base ring and ultrasonic transducer fixture carries out thread connection, and effect is fixing dicyclo hollow shape leading screw support, and then the fixing online device of changing; Upper apical ring is connected with threads of lead screw, in order to supporting leading screw, and makes its boot activity adjusting rod reciprocating, with for convenience detach and fill again ultrasonic transducer.Between upper apical ring and lower base ring, except brace rod, be transmission, therefore its volume is light and handy; Its brace rod itself can be used as the force is installed, and manually gets final product, and need not by instruments such as spanner, pipe wrench; Be withdrawn into the centre of dicyclo hollow shape leading screw support when ultrasonic transducer by the activity adjustment bar, in the time of namely between upper apical ring and lower base ring, namely can carry out every technical finesse to ultrasonic transducer; After being disposed, can carry out multiple dress; And needn't be as original technology, whole on-line equipment and the activity adjustment bar that is loaded with ultrasonic transducer are all disassembled the more unnecessary secondary installing changing device more online that carries out connecting the internal thread place.The whole operating process of the utility model, namely simple and convenient, the Concentricity tolerance that brings when more there is no the online more changing device of secondary installing, and the deviation of upper-lower position, thus guaranteed original accuracy of ultrasonic flowmeter.
The utility model volume is light and handy, and material-saving saves labor; Operation is simple and reliable, need not specific purpose tool; Guarantee that the original accuracy of flowmeter is constant.The utility model is simple in structure, and volume is light and handy, can directly overhaul, safeguards, changes and answer dress on ultrasonic transducer.
