Abstract
The utility model provides an externally clamped ultrasonic standard measuring pipe section, which comprises a standard pipe section, a sensor seat, a sensor and a sensor sealing cover. The sensor seat is disposed on the standard pipe section, the sensor is disposed inside the sensor sealing cover, the standard pipe section is connected with the sensor, and the sensor sealing cover is covered on the sensor seat to form an inner cavity for mounting the sensor. The externally clamped ultrasonic standard measuring pipe section adopts a standard pipe section as a measuring pipeline, increases a traditional externally-clamped flowmeter from one-dimensional flow speed measurement to three-dimensional volume flow measurement, more guarantees mounting position of the sensor to be correct, eliminates micro adjustment, avoids the problem that coupling agent of the senor requires frequent maintenance, and facilitates being picked for calibration.
Description
Technical field
The utility model relates to a kind of sensor, particularly a kind of external clamping ultrasound wave canonical measure pipeline section.
Background technology
Existing external clamping ultrasonic sensor adopts contactless mounting means, directly is installed on the in-site measurement pipeline.
Owing to directly be installed on the in-site measurement pipeline, therefore can have following problem:
1, the installation site accuracy is difficult to guarantee, introduces measuring error;
2, the sectional area of erecting stage pipeline can't accurately be measured, and introduces measuring error;
3, surface of contact is installed and is exposed in the air, need regularly sensor to be safeguarded;
3, the correction accuracy that presss from both sides sensor outward can't be delivered to the scene.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of external clamping ultrasound wave canonical measure pipeline section of accurate positioning.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of external clamping ultrasound wave canonical measure pipeline section is provided, it comprises prover section, sensor base, the metal wire-passing tube, sensor and sensor gland bonnet, described sensor base are arranged on this prover section, and described sensor is arranged in this sensor gland bonnet, described metal tube is connected with this sensor gland bonnet, and described sensor gland bonnet is fastened on this sensor base.
The technical scheme that its technical matters that solves the utility model adopts is: the interface of described sensor and this prover section is provided with couplant.
The technical scheme that its technical matters that solves the utility model adopts is: the size of described prover section and existing pipeline section coupling.
The technical scheme that its technical matters that solves the utility model adopts is: between described sensor gland bonnet and this sensor base by groove is set, and packoff is installed in groove, form the sensor installation inner chamber, make sensor in inner chamber, reach the stop-off lacquer effect.
Compared to prior art, external clamping ultrasound wave canonical measure pipeline section of the present utility model is by on the pipeline section that sensor base is set up standard, again described sensor is installed in the sensor gland bonnet, during installation, only need this prover section with on existing pipeline section directly is connected, just can guarantee sensor the installation site accurately, eliminate the microspur adjustment.Adopt prover section as measuring channel, 1 dimension fluid-velocity survey of traditional external clamping flowmeter is risen to the volume flow measurement of 3 dimensions.Described sensor gland bonnet is fastened on this sensor base, this sensor is sealed in this sensor gland bonnet fully, make the couplant of interface setting of this sensor and this prover section avoid coming out, can guarantee moistening state for a long time, needing avoid the often problem of maintenance.The integral design of this external clamping ultrasound wave canonical measure pipeline section makes the problem that its non-existent on-the-spot precision can't be reappeared, and the scene need not to cut off the water, and also can take off easily and examine and determine.
Description of drawings
Fig. 1 is the structural representation of external clamping ultrasound wave canonical measure pipeline section of the present utility model.
Fig. 2 is the cross-sectional view that the sensor base of external clamping ultrasound wave canonical measure pipeline section of the present utility model cooperates with the sensor gland bonnet.
Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
As Fig. 1 and shown in Figure 2, external clamping ultrasound wave canonical measure pipeline section of the present utility model comprises prover section 10, sensor base 11, metal wire-passing tube 12, sensor 13 and sensor gland bonnet 14.Described sensor base 11 is arranged on this prover section 10, described sensor 13 is arranged in this sensor gland bonnet 14, described metal wire-passing tube 12 is connected with this sensor gland bonnet 14, and described sensor gland bonnet 14 is fastened on this sensor base 11.
Described sensor base 11 is welded on this prover section 10, and this sensor 13 is installed in this sensor gland bonnet 14.Described sensor 13 is provided with couplant with the interface of this prover section 10, and forms the sealing gland effect.
The size of described prover section 10 and existing pipeline section coupling guarantee its versatility in use.
The other end of described metal wire-passing tube 12 links to each other with terminal box or transmitter.
By groove is set, and packoff is installed between described sensor gland bonnet and this sensor base, is made the inner chamber of sensor installation reach the stop-off lacquer effect.
Be provided with spring 15 and packoff 16 between described sensor gland bonnet 14 and this sensor base 11.
Described external clamping ultrasound wave canonical measure pipeline section is by being installed in sensor in the sensor gland bonnet 14, again described sensor base 11 is welded on this prover section 10, during installation, only need this prover section 10 with on existing pipeline section directly is connected, just can guarantee sensor the installation site accurately, eliminate the microspur adjustment.Described sensor gland bonnet 14 is fastened on this sensor base 11, with the complete stop-off lacquer of this sensor in this end cap, make the couplant of interface setting of this sensor and this prover section 10 avoid coming out, can guarantee moistening state for a long time, the problem that the need of avoiding are often safeguarded.The integral design of this external clamping ultrasound wave canonical measure pipeline section makes the problem that its non-existent on-the-spot precision can't be reappeared, and the scene need not to cut off the water, and also can take off easily and examine and determine.
