Abstract

The utility model relates to a sensor with 135 degrees bending pipe, comprising a bending pipe and a measuring mouth, one end at the 90 degrees bending pipe is extending with a 45 degrees reverse bending pipe, the measuring mouth is divided into an inner side and an outer side that are symmetrically positioned at the 45 degrees central line of the 90 degrees bending pipe. The pipe bending sensor can be acted as a one time detecting component of the pipe bending sensor, is conveniently applied in the junction of the pipeline with a 135 degrees bending, is convenient to choose and install the measuring component, broadens the application condition of the pipe bending flowmeter and extends the use of the pipe bending flowmeter, and has good promotion value.

Description

135 degree Bending Tube Sensors

Technical field

The utility model relates to a kind of flow detecting element, refers in particular to a kind of Bending Tube Sensor of realizing that 135 degree are turned, as the primary detecting element of elbowmeter.

Background technology

Because elbowmeter has no additonal pressure loss, non-maintaining, high reappearance and the advantages such as adaptability good to industry spot, and is widely used in fluid metering.Using the winding pipe flow rate timing, needing to use Bending Tube Sensor as its primary detecting element.The principle of work of Bending Tube Sensor is: when fluid flows through bend pipe with certain flow velocity, because the radius-of-curvature difference of bend pipe medial and lateral, the centrifugal force difference that causes medial and lateral to experience, by measuring the method for its inside and outside survey centrifugal force difference, by the size of elbowmeter through specific algorithm measurement velocity in pipes.When tubing, owing to be subjected to the restriction of many conditions such as construction space and application, make process layout become intricate, and existing Bending Tube Sensor only limits to use at 90 degree turnings of industrial pipeline, bring inconvenience for the installation of traditional elbowmeter, thereby limited the application of elbowmeter in many occasions.

Summary of the invention

The purpose of this utility model provides a kind of Bending Tube Sensor that is used for process pipeline 135 degree turnings.

Technical solution adopted in the utility model is: a kind of 135 degree Bending Tube Sensors, constitute by a bend pipe and a measurement mouthful institute, described bend pipe is outward extended with the 45 reverse bend pipes of spending for the end at 90 degree bend pipes, and described measurement mouth branch medial and lateral are symmetricly set on the 45 degree center lines of 90 degree bend pipes.

The beneficial effects of the utility model are: this Bending Tube Sensor can be used as the primary detecting element of elbowmeter, be conveniently used in having the process pipeline junction that 135 degree are turned, selecting for use and installing measuring sensor in being convenient to construct, widened the application conditions of elbowmeter, expand the usage space of elbowmeter, had excellent generalization values.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.

A kind of 135 degree Bending Tube Sensors as shown in Figure 1 are made of

bend pipe

1 and 2 in measurement mouth, and bend pipe 1 is outward extended with the reverse bend pipe of 45 degree for the end at 90 degree bend pipes, and constitutes continuous 135 bend pipes of spending.Measure mouthful 2 fens medial and lateral and be symmetricly set on the 45 degree center lines of 90 degree bend pipes, and be connected with elbowmeter by measurement line.When fluid flows through bend pipe with certain flow velocity, because the radius-of-curvature difference of bend pipe medial and lateral, the centrifugal force difference that causes medial and lateral to experience is by measuring the method for its inside and outside survey centrifugal force difference, by the size of elbowmeter by flow in the special algorithm measuring tube of 135 degree bend pipes.

Claims

A kind of 135 degree Bending Tube Sensors, constitute by a bend pipe and a measurement mouthful institute, it is characterized in that: described bend pipe is outward extended with the one 45 reverse bend pipes of spending for the end at 90 degree bend pipes, and described measurement mouth branch medial and lateral are symmetricly set on the 45 degree center lines of 90 degree bend pipes.
