Abstract
The utility model relates to an internal type V-cone flowmeter for measuring large-diameter gas flow, which comprises a shell and a flangeless small-diameter V-cone flowmeter (6), wherein flanges (8) are arranged at the two ends of the shell (5) and the flangeless small-diameter V-cone flowmeter (6) is internally arranged in the shell. The positive and negative pressure tapping pipe of the flangeless small-diameter V-cone flowmeter (6) penetrates through the shell and is connected with a differential pressure transmitter. The flangeless small-diameter V-cone flowmeter (6) is fixedly connected with the shell (5) through a support (7). Compared with the prior art, the utility model has the advantages that the impurities can be easily blown away by the medium because the V-cone flowmeter has no dead zone of fouling, and the impurities do not block the pressure tapping holes because the positive pressure tapping hole is arranged above the pipe wall, the negative pressure tapping hole is arranged at the rear part of the cone and both pressure tapping holes are arranged at the downstream of the fluid flowing direction; the measuring accuracy is high; and the permanent pressure loss is very small.
Description
Technical field
The utility model relates to the differential pressure flowmeter technical field, particularly a kind of built-in V-type cone flow meter of measuring the heavy caliber gas flow.
Background technology
In the prior art, be that the weak point that the differential pressure flowmeter of representative exists is with Annubar, Verabar, double-venturi tube: the malleation pressure port makes the impurity in the fluid stop up pressure port towards the fluid upstream, makes and measures failure.
Summary of the invention
The purpose of this utility model has provided a kind of novel built-in V-type cone flow meter.
Implementation of the present invention is as follows:
Built-in V-type cone flow meter comprises:
Two ends are provided with the shell 5 of flange 8, be built in the shell can't blue small-bore V-type cone flow meter 6, above-mentioned positive negative pressure pressure pipe that can't blue small-bore V-type cone flow meter runs through shell and is connected with differential pressure transmitter, can't be fixedly connected by support 7 and shell 5 by blue small-bore V-type cone flow meter.
Above-mentioned shell 5 can be a circular pipe.The axial line of above-mentioned shell can be built in shell in can't overlap by blue small-bore V-type cone flow meter axial line; The axial line of above-mentioned shell also can be built in shell in can't not overlap by blue small-bore V-type cone flow meter axial line, can't blue small-bore V-type cone flow meter axial line be 1/8th of housing diameter apart from the distance of tube wall.
Above-mentioned shell 5 also can be a square pipe.The center line of above-mentioned shell can be built in shell in can't overlap by blue small-bore V-type cone flow meter axial line; The center line of above-mentioned shell also can be built in shell in can't not overlap by blue small-bore V-type cone flow meter axial line, can't blue small-bore V-type cone flow meter axial line be 1/8th of the relative tube wall distance of this tube wall apart from the distance of tube wall with it.
Principle of work of the present utility model: in measured medium is flowed through measuring tube can't blue small-bore V-type cone flow meter, this V-type cone flow meter produces certain differential pressure, link to each other with differential pressure transmitter through positive and negative pressure pipe, and measure differential pressure value, square being directly proportional of differential pressure value and measured flux.
The present invention is with respect to the advantage of prior art:
(1) since the V-type cone flow meter do not have incrustation dead angle impurity to be easy to be blown away by medium, simultaneously, the malleation pressure port above tube wall the negative pressure pressure port at the cone rear portion, in the downstream of direction of flow, so impurity can not stop up pressure port.
(2) measuring accuracy height;
(3) the permanent compression loss is very little.
