Abstract

The utility model relates to a device for measuring fluid flow in a pipeline through ultrasonic waves, in particular to an on-line type ultrasonic wave plug-in sensor. The utility model adopts the technical scheme that the on-line type ultrasonic wave plug-in sensor comprises a probe rod (1), a base (2) and a spherical valve (3), wherein the spherical valve (3) is fixedly arranged on the base (2), the probe rod (1) penetrates through the spherical valve (3), external threads are formed on the probe rod (1), internal threads are formed in the spherical valve (3), and the probe rod (1) is matched with the spherical valve (3) through the threads; and a lock nut (4) is also arranged and sleeved on the probe rod (1), and the internal threads of the lock nut are matched with the external threads of the probe rod. The utility model can avoid the ejection of the probe rod since the probe rod and the spherical valve are connected through the threads in a matched manner, and the probe rod can be directly screwed into the spherical valve through the threads formed thereon; and the sensor can be firmly fixed due to the coordination use of the lock nut, thereby avoiding displacement, and ensuring the measuring accuracy.

Description

At line style ultrasound wave plug in sensor
Affiliated technical field:
The utility model relates to a kind of device with ultrasonic measurement pipeline liquid flow, particularly at line style ultrasound wave plug in sensor.
Background technology:
At present, the ultra sonic wave flow meter insertion type sensor is used widely in liquid measure, ultra sonic wave flow meter insertion type sensor commonly used is formed and is comprised: feeler lever (probe rod), base, ball valve, lock sleeve etc., retaining problem when general employing steel band, iron chains etc. solve feeler lever insertion ball valve, manifold pressure is excessive when preventing to install, and feeler lever is deviate to hurt sb.'s feelings, still, this structural reliability is poor, and security does not guarantee.In addition, on lock sleeve, locate feeler lever with set screw, prevent that feeler lever from moving, in use vibration often appears in pipeline, cause set screw loosening, make feeler lever rotation or mobile occur, will cause ultrasonic flow meter signal quality and signal intensity to descend if feeler lever is subjected to displacement, accuracy error occurs, can't use sometimes.
The utility model content:
The utility model purpose provides a kind of at line style ultrasound wave plug in sensor, avoids feeler lever to deviate from during online installation, and is safe and reliable, prevents that displacement from appearring in sensor, guarantees measuring accuracy, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: comprise feeler lever, base, ball valve at line style ultrasound wave plug in sensor, ball valve is fixedly installed on the base, and feeler lever passes in ball valve, and feeler lever is provided with external thread, be provided with internal thread in the ball valve, feeler lever and ball valve mate mutually by screw thread.
The utility model also is provided with set nut, is enclosed within on the feeler lever, and the internal thread of set nut and the external thread of feeler lever are complementary, and set nut withstands on the ball valve, and feeler lever, ball valve closely combine by set nut.
In order to increase sealing, set nut is provided with groove, and groove is provided with rubber seal.
Adopt the utility model, owing to connect by the screw thread coupling between feeler lever and the ball valve, feeler lever is provided with screw thread can directly screw in ball valve, the situation that feeler lever is deviate from can not occur; Lock the use of nut, fixation of sensor that can be firm prevents displacement, guarantees measuring accuracy.
The utlity model has rational in infrastructure, avoid feeler lever deviate from, safe and reliable, prevent that sensor from displacement occurring, guaranteeing characteristics such as measuring accuracy.
Description of drawings:
Accompanying drawing 1 is the utility model example structure synoptic diagram.
Accompanying drawing 2 is a ball valve female thread structure synoptic diagram among the utility model embodiment.
Among the figure: feeler lever 1, base 2, ball valve 3, set nut 4, connector cover 5, O-ring seal 6, cable locking nut 7, ball valve internal thread 8.
Embodiment:
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
Comprise feeler lever 1, base 2, ball valve 3 at line style ultrasound wave plug in sensor, ball valve 3 is fixedly installed on the base 2, and feeler lever 1 passes in ball valve 3, and feeler lever 1 is provided with external thread, is provided with internal thread 8 in the ball valve 3, and feeler lever and ball valve mate mutually by screw thread; Also be provided with set nut 4, be enclosed within on the feeler lever 1, the internal thread of set nut and the external thread of feeler lever are complementary, and set nut 4 withstands on the ball valve 3, and feeler lever, ball valve closely combine by set nut.
Earlier base 2 is welded on the pipeline, the screw thread by ball valve 3 and base 2 is fixed on ball valve 3 on the base 2.Then set nut 4 is installed on the feeler lever 1 by the screw thread on the feeler lever, again by the screw thread between feeler lever 1 and the ball valve 3 with in the feeler lever 1 precession ball valve 3, transfer to the appropriate location after, set nut 4 is fastened on the ball valve, guarantee that feeler lever can not be subjected to displacement.At last, signal wire via cable set nut 7 is entered after the feeler lever terminal box locking cable set nut 7 and cover terminal box bonnet 5.
