The utility model adopts the technical scheme that the device comprises connecting flanges, a corrugated pipe, connecting screw rods and adjusting nuts; wherein the corrugated pipe is fixedly connected between two connecting flanges; the two connecting flanges are connected with a detection platform pipeline and a straight pipe section of the elbow sensor respectively; a plurality of corresponding adjusting holes are uniformly distributed on the outer circumference of the two connecting flanges; one connecting screw rod passes through every two corresponding adjusting holes; and the adjusting nuts are screwed at both ends of the connecting screw rod. In the utility model, when in detecting operation, flanges at both ends of the elbow sensor are connected with the connecting flanges of the clamping device respectively, the adjusting nut is adjusted, and insufficient or redundant length of the straight section at both ends of the elbow sensor, angle deviation and other defects are compensated and corrected by means of the retraction and torsion of the corrugated pipe.
Description
Technical field
The utility model relate to a kind of when elbowmeter is examined and determine the device of clamping Bending Tube Sensor, belong to technical field of measuring equipment.
Background technology
Elbowmeter is as a kind of measuring products, and its advantage has obtained measuring the approval on boundary, and is widely used in industry gradually, a plurality of fields such as public utilities.The advantage of elbowmeter is mainly reflected in aspects such as principle is reliable, simple in structure, energy-saving and cost-reducing, maintenance is few, the primary sensing element of elbowmeter---Bending Tube Sensor is applicable to abominable industrial environment, for various abominable field conditions such as high temperature, high pressure, humidity, dust, vibrations good applicability is arranged, can be to Φ 20-Φ 2000mm, even bigger pipeline carries out accurate flow measurement.Under the cooperation of intelligent instrument specially for same or modular converter, can satisfy the demand in the flow measurement of liquid, gas and steam of industry-by-industries such as electric power, heating power, metallurgy, iron and steel, oil, chemical industry, machinery, weaving, papermaking, pharmacy, food processing and public utilities.Its application and development prospect are wide.
In the making and use of elbowmeter, the measuring accuracy of elbowmeter and repeatable playback accuracy can be subjected to the influence of the quality of elbowmeter own, comprise verticality, levelness, torsion resistance, out-of-roundness, uniformity coefficient of elbowmeter etc., also be subjected to simultaneously the influence of installation quality, therefore to the calibrating of elbowmeter be make and use in requisite important step.
Existing Flowmeter Verification System is the system that is used to examine and determine flowmeter on the straight length, and pipeline is arranged and is linear pattern, and promptly the axis of straight length all is located on the same line after the preceding straight length of system, calibrating section, the system.Used clamping device generally adopts meter-clamping apparatus, makes movable end move forward and backward by manual, pneumatic or hydraulic pressure during meter-clamping apparatus work, and tested table is clamped.Because the core component tube sensor that elbowmeter is installed on the pipeline is made up of three parts, be Bending Tube Sensor body and forward and backward straight length, adopt welding to connect between the three, therefore in the manufacture process of elbowmeter, will produce multiple size and dimension error.Meter-clamping apparatus commonly used only can compensate a scale error on the direction, and can not compensate error on other direction, like this, if only use meter-clamping apparatus as clamping device this moment, can not guarantee that Bending Tube Sensor can install smoothly, therefore be necessary to design new clamping device, to guarantee to finish the calibrating of elbowmeter.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of device that can realize the clamping Bending Tube Sensor of multidirectional linearity and angle compensation when elbowmeter is examined and determine to Bending Tube Sensor.
The technical scheme that solves the problems of the technologies described above is:
A kind of when checking elbow meter the device of clamping Bending Tube Sensor, it is made up of joint flange, corrugated tube, connecting screw rod, adjustment nut, joint flange is two, corrugated tube is fixedly connected between two joint flanges, two joint flanges are connected with the Bending Tube Sensor straight length with calibrating platform pipeline respectively, on the excircle of two joint flanges, also be evenly equipped with the adjustment hole of a plurality of correspondences, there is a connecting screw rod to pass between per two corresponding adjustment holes, there is screw thread at the two ends of connecting screw rod, adjust the two ends that nut is spun on connecting screw rod.
Above-mentioned when checking elbow meter the device of clamping Bending Tube Sensor, described each joint flange is made up of the flange of two separation, a flange is connected with corrugated tube, the adjustment hole is arranged on its circumference, another flange is connected with calibrating platform pipeline or Bending Tube Sensor, has communicating pipe fixedly connected in the middle of these two flanges.
Above-mentioned when checking elbow meter the device of clamping Bending Tube Sensor, described corrugated tube is the flexible corrugated tube of stainless steel.
Adopt the device of the clamping Bending Tube Sensor of this structure, when the calibrating operation, Bending Tube Sensor is placed on the calibrating platform, its two end flanges is connected with the joint flange of clamping device respectively, again by regulate adjusting nut, rely on the flexible of corrugated tube and reverse defectives such as the curtailment of Bending Tube Sensor two ends straight section or unnecessary, angular deviation are compensated and correct.
