Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic heat meters, and particularly relates to an insert for the base meter of an ultrasonic heat meter. Background Art

[0002] An ultrasonic heat meter is an instrument used to measure and display the thermal energy released or absorbed by water flowing through a heat exchange system. After calculation and processing, it shows the heat released by the measured fluid from the inlet end to the return end.

[0003] Currently, the existing base meters of heat meters are made of other metal materials such as copper or stainless steel. During the process of transporting hot water, scale is easily generated on the inner wall of the base meter pipe section, especially in hard water areas. Hard water contains a large amount of metal ions such as calcium and magnesium. These ions will combine with carbonate radicals in water to form insoluble compounds such as calcium carbonate and magnesium carbonate, which adhere to the inner wall of the copper pipe, forming scale. The formation of scale will not only affect the transmission of the heat meter signal, thereby affecting the measurement accuracy, but also reduce the water flow and thermal conductivity, and is also prone to cause corrosion of the inner wall of the copper pipe, resulting in problems such as water leakage. Therefore, some base meters of heat meters use corrosion-resistant non-metallic materials as the main body of the base meter.

[0004] For the existing base meters of heat meters made of non-metallic materials, due to the low strength of some non-metals, the reflection columns inside the base meter are not firmly fixed, resulting in the shaking of the reflection columns and affecting the measurement accuracy. Summary of the Utility Model

[0005] Therefore, the embodiment of the utility model provides an insert for the base meter of an ultrasonic heat meter to solve the above-mentioned technical problems.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] An insert for the base meter of an ultrasonic heat meter includes two annular pipe fittings. Ultrasonic sensor mounting seats communicating with the inside of the pipe fittings are arranged on the outer side walls of the two annular pipe fittings for installing ultrasonic sensors. A temperature sensor mounting seat communicating with the inside of the annular pipe fitting is arranged on one side of one of the annular pipe fittings for installing a temperature sensor. A limiting groove is opened on the inner side wall of the annular pipe fitting on the side opposite to the ultrasonic sensor mounting seat for fixing the reflection column. The two annular pipe fittings are fixed inside the side wall of the housing of the base meter of the ultrasonic heat meter, and the ultrasonic sensor mounting seat corresponds to the position of the ultrasonic sensor on the base meter of the ultrasonic heat meter, and the temperature sensor mounting seat corresponds to the position of the temperature sensor on the base meter of the ultrasonic heat meter.

For a solution with a time sequence process, this way of term expression does not have to be understood as describing a specific order or sequence, and for a solution of a device structure, this way of term expression also does not distinguish the importance degree, positional relationship, etc.

[0028] In addition, the terms "comprising", "having", and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units need not be limited to those steps or units that are explicitly listed, but may also include other steps or units that are inherent to these processes, methods, products, or devices although not explicitly listed, or steps or units added based on further optimization solutions of the inventive concept of the present utility model.

[0029] As Figures 1 - 3 shown, an ultrasonic heat meter base meter insert disclosed by the present utility model includes two annular pipe fittings 1. An ultrasonic sensor mounting seat 2 communicating with the inside of the pipe fitting is provided on the outer side wall of each of the two annular pipe fittings 1 for mounting an ultrasonic sensor. A temperature sensor mounting seat 3 communicating with the inside of the annular pipe fitting 1 is provided on one side of one of the annular pipe fittings 1 for mounting a temperature sensor. A limiting groove 4 is provided on the inner side wall of the annular pipe fitting 1 opposite to the ultrasonic sensor mounting seat 2 for fixing a reflection column. The two annular pipe fittings 1 are fixed inside the side wall of the housing of the ultrasonic heat meter base meter, and the ultrasonic sensor mounting seat 2 corresponds to the position of the ultrasonic sensor on the ultrasonic heat meter base meter, and the temperature sensor mounting seat 3 corresponds to the position of the temperature sensor on the ultrasonic heat meter base meter; an ultrasonic sensor mounting hole 18 is provided in the ultrasonic sensor mounting seat 2 for mounting an ultrasonic sensor, and a temperature sensor mounting hole 19 is provided in the temperature sensor mounting seat 3 for mounting a temperature sensor.

[0030] The above-mentioned annular pipe fitting 1 is made of a metal material and, as a metal insert, is embedded inside the housing of the ultrasonic heat meter base meter to improve the strength of the ultrasonic heat meter base meter;

[0031] The two annular pipe fittings 1 are integrally formed with the housing of the ultrasonic heat meter base meter. Through injection molding, the annular pipe fittings are directly formed inside the wall thickness of the housing, and the ultrasonic sensor mounting seat 2 and the temperature sensor mounting seat 3 on the annular pipe fitting 1 are covered. A temperature sensor and an ultrasonic sensor are respectively mounted on the temperature sensor mounting seat 3 and the ultrasonic sensor mounting seat 2. The specific mounting structure and mounting method can adopt the existing mounting structure and will not be elaborated herein;

[0032] In addition, a limiting groove 4 is provided at the bottom of the inner wall of the annular pipe fitting 1 (the ultrasonic sensor mounting seat 2 is regarded as the top of the annular pipe fitting 1), and a reflection column can be fixed at the limiting groove 4. The angle of the limiting column is ensured by the metal annular pipe fitting 1 to guarantee the measurement accuracy.

[0033] In a further embodiment, a plurality of connecting ribs 5 are provided between the ends of the two annular pipes 1, both ends of the connecting ribs 5 are fixedly connected to the two annular pipes 1, and the plurality of connecting ribs 5 are distributed in a circumferential array at the ends of the annular pipes 1. Two adjacent connecting ribs 5 are arranged at intervals, and the gap between the two connecting ribs 5 forms a connecting port 6.

[0034] A connecting rib 5 is provided between the two annular pipe fittings 1. The connecting rib 5 is also made of metal. The connecting rib 5 and the annular pipe fitting 1 are integrally formed. During the injection molding process in which the annular pipe fitting 1 is embedded in the shell of the ultrasonic heat meter base, the shell is formed and fixed inside and outside at the connecting rib 5, thereby further making the heat-resistant polyethylene shell of the ultrasonic heat meter base more tightly connected to the annular pipe fitting 1, thereby ensuring sufficient strength of the base, and reinforcing the structure of the two annular pipe fittings 1 to ensure that the angle of the reflection column will not change.

[0035] In addition, a plurality of tooth-shaped notches 7 may be distributed in a circumferential array at the ends of the two annular pipes 1 that are away from each other.

[0036] An annular groove 8 recessed into the annular tube is provided on the outer side wall of the annular tube 1 near the tooth-shaped notch 7 .

[0037] The arrangement of the above-mentioned tooth-shaped notches 7 and annular grooves 8 forms an interlaced bite structure at the tooth-shaped notches 7 and an annular block structure in the annular grooves 8 during the injection molding process of the shell and the metal insert, thereby improving the connection strength between the annular pipe 1 and the heat-resistant polyethylene shell in all directions.

[0038] In a further embodiment, in order to prevent water from penetrating into the housing, a first O-ring installation groove 9 is provided on the outer wall of the ultrasonic sensor mounting seat 2. A second O-ring installation groove 10 is provided on the outer wall of the temperature sensor mounting seat 3.

[0039] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0040] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0041] In the foregoing, the present utility model has been described in a relatively specific and detailed manner through general descriptions and specific embodiments. It should be noted that, without departing from the concept of the present utility model, it is obvious that several modifications and improvements can still be made to these specific embodiments, and these all fall within the protection scope of this application. Therefore, the protection scope of the patent of this application shall be subject to the appended claims.
