Abstract

The utility model relates to sensor technical field more particularly to a kind of Verabar flow apparatus.In the prior art, for a long time under severe test environment, the blocking and fouling and precipitating inside pipeline that will cause Verabar probe influence measurement accuracy.In order to solve the above problem, the technical solution adopted is that including sequentially connected differential pressure transmitter, connecting pipe and Verabar flow probe, and the tested pipeline being connect with Verabar flow probe, the Verabar flow probe protrudes into inside the tested pipeline, medium separating and filtering net is removably installed on the tested pipeline, the medium separating and filtering net covers the cross section of the tested pipeline and is located on front side of Verabar flow probe.The utility model is equipped in the front end of Verabar flow probe and has been removably installed medium separating and filtering net, is filtered to detected unidirectional gas or liquid, and impurity is avoided to enter detected region, influences detection accuracy and causes the dirty of detection pipeline.

Description

A kind of Verabar flow apparatus

Technical field

The utility model relates to sensor technical field more particularly to a kind of Verabar flow apparatus.

Background technique

Verabar is a kind of differential pressure type flow instrument, has extensive use, it is suitable for full packages one-way flow Flow measurement, measurement and the process control of the media such as single phase gas, liquid and steam, dielectric viscosity are not more than 10 centipoises.

However there is some shortcomingss in use for existing Verabar, and under normal circumstances, ash Dirt, sand and particle etc. can all concentrate on the rear portion of probe under the action of vortex street power, but be in severe test wrapper for a long time Under border, the blocking and fouling and precipitating inside pipeline that will cause Verabar probe influence measurement accuracy.

Utility model content

The utility model mainly solves defect existing for present technology, provides a kind of Verabar flow apparatus.

In order to solve the above technical problems, the technical solution adopted in the utility model is:

A kind of Verabar flow apparatus, including sequentially connected differential pressure transmitter, connecting pipe and Verabar flow probe, with And the tested pipeline being connect with Verabar flow probe, the Verabar flow probe protrudes into inside the tested pipeline, described Medium separating and filtering net is removably installed on tested pipeline, the medium separating and filtering net covers the cross of the tested pipeline Section and be located at Verabar flow probe on front side of.

Preferably, the tested pipeline includes the first tested pipeline and the second tested pipeline being fixedly connected by flange, The medium separating and filtering net between the first tested pipeline and the second tested pipeline, by flange and the first tested pipeline and The opposite face of second tested pipeline fits closely.

Preferably, the flange and the first tested pipeline, flange and the second tested pipeline are integrally casting shaping.

It preferably, further include three valve groups, three valve group is between differential pressure transmitter and connecting pipe.

It preferably, further include shut-off valve, the shut-off valve is between connecting pipe and Verabar flow probe.

Preferably, the medium separating and filtering net is gas-liquid filter net or solid-liquid filtration net.

The utility model has the beneficial effects that

The utility model provides a kind of Verabar flow apparatus, is equipped in the front end of Verabar flow probe and removably pacifies Equipped with medium separating and filtering net, detected unidirectional gas or liquid are filtered, impurity entrance is avoided to be detected Region influences detection accuracy and causes the dirty of detection pipeline.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of Verabar flow apparatus of the utility model.

Figure label is as follows:

Differential pressure transmitter 1；Three valve groups 2；Connecting pipe 3；Shut-off valve 4；Verabar flow probe 5；Medium separating and filtering net 6.

Specific embodiment

The following figure be described with reference to the drawings and specific embodiment the present invention will be further described.

As shown in Figure 1, the utility model provides a kind of Verabar flow apparatus, arrow direction is the side that fluid passes through To, including sequentially connected differential pressure transmitter 1, connecting pipe 3 and Verabar flow probe 5, and connect with Verabar flow probe 5 The tested pipeline connect, the Verabar flow probe 5 protrude into inside the tested pipeline, removably pacify on the tested pipeline Equipped with medium separating and filtering net 6, the medium separating and filtering net 6 covers the cross section of the tested pipeline and is located at Verabar stream 5 front side of amount probe.

Wherein, differential pressure transmitter also can be replaced into flow converter, can measure fluid flow.

In the present embodiment, the tested pipeline includes that the first tested pipeline being fixedly connected by flange and second are tested Pipeline, the medium separating and filtering net 6 are tested by flange and first between the first tested pipeline and the second tested pipeline The opposite face of pipeline and the second tested pipeline fits closely.

In the present embodiment, medium separating and filtering net 6 uses dismountable connection type, facilitates the replacement of filter screen, Reduce the difficulty of pipeline cleaning.

In the present embodiment, the flange and the first tested pipeline, flange and the second tested pipeline be integrally casting at Type.

It in the present embodiment, further include three valve groups 2, three valve group 2 is between differential pressure transmitter 1 and connecting pipe 3.

In the present embodiment, further include shut-off valve 4, the shut-off valve 4 be located at connecting pipe 3 and Verabar flow probe 5 it Between.

The utility model provides two kinds of embodiments, and first embodiment is to detect the Verabar flow apparatus of unidirectional gas, this When medium separating and filtering net be gas-liquid filter net, gas-liquid filter net is made of corrosion resistant stainless steel material, gas to be detected Body first passes through gas-liquid filter net and carries out gas-liquid separation, enters back into detected pipeline, detection accuracy can be improved.

Second embodiment is to detect the Verabar flow apparatus of unidirectional liquid, and medium separating and filtering net 6 at this time is solid-liquid Filter screen, the liquid with detection first pass through solid-liquid filtration net and are separated by solid-liquid separation, and enter back into detected pipeline, detect improving Sensor and pipeline can also be caused to damage under the drive of high-velocity fluid to avoid solid granule while precision.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure made based on the specification and figures of the utility model is applied directly or indirectly in other relevant technologies Field is also included in the patent protection scope of the utility model.
