Abstract

The utility model discloses an assembled bended pipe sensor, which is composed of a bended pipe 1 and an installation mouth for a pressure measurement apparatus 7, wherein, the bended pipe 1 is an integrative bended pipe; the bended pipe 1 and a measured pipeline 2 are firmly and fixedly connected through flange discs 4, 3, 4`, 3`; sealed rubber ring mats 5, 5` are arranged in parallel between the flange discs. The assembled bended pipe sensor is simple in structure, easy to be operated with less time and fewer labors at the time of cleaning the scale inside the pipe, and reduces the effect to the production, assures the measurement accuracy, and can be widely used for the measurement of the fluid flow inside the pipe.

Description

The assembly type Bending Tube Sensor

The utility model relates to a kind of improvement of Bending Tube Sensor, and specifically a kind of assembly type Bending Tube Sensor is applicable to the mensuration of fluid flow in the pipeline.

Employed Bending Tube Sensor is to be made of bend pipe and pressure tester installing port in the flow of measuring pipeline fluid at present, and its bend pipe is circular-arc and pipeline directly is welded, and bend pipe length is 1/4 circular arc, and the bend pipe caliber is consistent with the caliber of tested pipeline.This elbowmeter can produce certain dirt on the tube wall in the utilization process, when dirt can not in time be removed, can produce certain influence to the pressure of bend pipe medial and lateral, and measuring error is strengthened.In order in time to remove dirt in the pipe, the design that has the bend pipe that combines by upper and lower two and half bend pipes, be 00202137.4 Patent project as application number, when in the pipe during generation dirt, can take two and half bend pipes apart, clear up.But this bend pipe combination point of fixity is more, and maintenance operation is complicated, and loading and unloading are taken a lot of work more, can not resume production fast.

The purpose of this utility model be to provide a kind of simple in structure, maintenance operation is easy, time saving and energy saving, the assembly type Bending Tube Sensor that can improve measuring accuracy.

The utility model is achieved in that this assembly type Bending Tube Sensor, constitute by bend pipe and pressure tester installing port, the as a whole bend pipe of its bend pipe, a bend pipe ring flange is respectively welded at the two ends of bend pipe, also respectively weld a pipeline opening ring flange on two oral areas of corresponding tested pipeline, between bend pipe ring flange and pipeline opening ring flange, be provided with the packer ring pad.Behind rubber ring pad on the pad between bend pipe ring flange and the pipeline opening ring flange, fastening with fastening bolt; The diameter of bend pipe is consistent with measured tube road junction diameter, and packer ring pad internal diameter is consistent with pipeline opening or bend pipe mouth internal diameter, and the rubber ring pad external diameter is consistent with the ring flange external diameter, and bend pipe length is 1/4 circular arc.

The utility model has the advantages that: can not only in time clear up the dirt in the pipeline, improve and measure viscosity, and simple in structure, cleaning operation is easy, time saving and energy saving, do not influence production.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 looks synoptic diagram for the utility model structure master,

Fig. 2 is that the utility model is along the A-A cross-sectional schematic.

Make the utility model with reference to accompanying drawing 1,2.This assembly type Bending Tube Sensor, constitute by bend pipe 1 and pressure tester installing port 7, its bend pipe 1 as a whole bend pipe, bend pipe ring flange 3,3 in each welding of the two ends of bend pipe 1 ', two oral areas of corresponding tested pipeline 2 also respectively weld a pipeline opening ring flange 4,4 ', bend pipe ring flange 3,3 ' and pipeline opening ring flange 4,4 ' between be provided with packer ring pad 5,5 ', the connection between the ring flange is fastening with fastening bolt 6.
