Description

Flowmeter with replaceable inner core

Technical Field

The utility model belongs to fluid flow measurement field, concretely relates to removable inner core flowmeter.

Background

In the oil gas production and transportation process, the inside of the flowmeter is eroded due to the reasons of large fluid pressure, high flow speed, large fluctuation, large sand content and the like, so that the metering precision of the flowmeter is influenced, and safety accidents can be caused under severe conditions. Conventional flowmeters are replaced as soon as the interior is found to be eroded. In addition, the whole flowmeter is replaced when the flow fluctuation is large and exceeds the measuring range of the flowmeter. Because the flowmeter is expensive in manufacturing cost, the replacement of the whole flowmeter is extremely uneconomical and efficient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that just to above-mentioned prior art not enough, provide a removable inner core flowmeter, can replace the inner core through the change and can deal with various operating modes, adaptability improves greatly.

The utility model adopts the technical proposal that: the utility model provides a removable inner core flowmeter, includes the flowmeter body, this intracavity of flowmeter is equipped with and replaces the inner core, flowmeter body inner chamber both ends all are equipped with and extend to the inside and fixed mounting that can replace the inner core of inner chamber, flowmeter body both ends outside is equipped with the connecting piece, flowmeter body top is equipped with and extends to and can replace the inside signal sensor of inner core, can replace the inner core inboard and be equipped with signal generator.

In one embodiment, a position-limiting member is disposed between at least one end of the replaceable inner core and the inner cavity of the flowmeter body.

In one embodiment, a sealing element is arranged between the replaceable inner core and the fixing element at least at one end of the replaceable inner core.

The beneficial effects of the utility model reside in that:

1. the replaceable inner core corresponding to the working condition can be replaced according to the field working condition, so that the metering of the flowmeter is more accurate, the same flowmeter can cope with various working conditions, and the adaptability is greatly improved;

2. only the replaceable inner core is replaced, and the whole flowmeter is not required to be replaced, so that the method is more economical and efficient;

3. the replaceable inner core is positioned through the fixing pieces at the two ends and the inner cavity of the flowmeter body, the replaceable inner core can be limited from all directions, and the mounting precision and reliability of the replaceable inner core are guaranteed;

4. the sealing element and the limiting element are arranged, so that the sealing and limiting of the replaceable inner core can be realized.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a flowmeter body; 2. the inner core can be replaced; 3. a fixing member; 4. a connecting member; 5. a signal sensor; 6. a signal generator; 7. a seal member; 8. and a limiting member.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the flowmeter with the replaceable inner core comprises a flowmeter body 1, a replaceable inner core 2 is arranged in an inner cavity of the flowmeter body 1, fixing parts 3 which extend into the inner cavity and fix the replaceable inner core 2 are arranged at two ends of the inner cavity of the flowmeter body 1, connecting parts 4 connected with two ends of the flowmeter body 1 are arranged on outer sides of two ends of the flowmeter body 1, a signal sensor 5 which extends to the inner side of the replaceable inner core 2 is arranged at the top of the flowmeter body 1, and a signal generator 6 is arranged in the replaceable inner core 2.

In this embodiment, a limiting member 8 is disposed between at least one end of the replaceable inner core 2 and the inner cavity of the flowmeter body 1.

In this embodiment, a sealing member 7 is disposed between the replaceable inner core 2 and the fixing member 3 at least at one end thereof.

The flowmeter can replace the replaceable inner core 2 according to the actual working condition, and after replacement, the replaceable inner core 2 is fixed in the inner cavity of the flowmeter body 1 through the fixing piece 3; then connecting the connecting pieces 4 to two ends of the flowmeter body 1; and a signal sensor 5 and a signal generator 6 are respectively arranged. The sealing element 7 is arranged to realize the sealing of two ends of the replaceable inner core 2; the limiting piece 8 is arranged to fix the replaceable inner core 2 and limit the rotation of the replaceable inner core.

The connecting piece 4 described in the present application is a flange, union or screw thread or the like. The fixing part 2 is a screw thread or a clamp spring and other fixing parts. The limiting member 8 is a pin or a key.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
