Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic heat meters, and particularly relates to a socket-type heat-resistant polyethylene ultrasonic heat meter base 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 heat meter base meters are made of other metal materials such as copper or stainless steel. During the process of transmitting 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 ions in the 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 rate and heat conduction performance, and is also prone to cause corrosion of the inner wall of the copper pipe, resulting in problems such as water leakage. Content of the Utility Model

[0004] Therefore, the embodiment of the utility model provides a socket-type heat-resistant polyethylene ultrasonic heat meter base meter to solve the above-mentioned technical problems.

[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] In the description of the present utility model, unless otherwise specified, "a plurality of" means two or more. The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present utility model and the above - mentioned drawings are intended to distinguish the objects being referred to. For a solution with a time - sequence process, such a term expression does not necessarily need to be understood as describing a specific order or sequence. For a solution of a device structure, such a term expression also does not distinguish the importance level, positional relationship, etc.

[0032] 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 includes 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.

[0033] As Figures 1-7 shown, a socket-type heat-resistant polyethylene ultrasonic heat meter base meter disclosed by the present utility model includes a tubular housing 1. Two first positioning holes 2 communicating with the inside of the housing 1 are spaced apart on the housing 1. A second positioning hole 3 communicating with the inside of the housing 1 is provided on one side of the first positioning hole 2 below the medium flow direction inside the housing 1. A reflecting column 4 is provided at a position corresponding to the first positioning hole 2 inside the housing 1.

[0034] The housing 1 is made of heat-resistant and corrosion-resistant material. A metal insert 5 is provided between the inner wall and the outer wall of the housing 1. An ultrasonic sensor mounting seat is provided at a position corresponding to the first positioning hole 2 on the metal insert 5. A temperature sensor mounting seat 7 is provided at a position corresponding to the second positioning hole 3 on the metal insert 5. A reserved hole 8 is provided at a position corresponding to the reflecting column 4 on the housing 1. A limiting groove 9 is provided at a position corresponding to the reserved hole 8 and the reflecting column 4 on the metal insert 5 for fixing the reflecting column 4.

[0035] The shape of the above-mentioned housing 1 is substantially the same as that of a conventional ultrasonic heat meter base meter. The first positioning hole 2 and the second positioning hole 3 on the housing 1 are both conventionally arranged. The second positioning hole 3 is provided on one side of the first positioning hole 2 located downstream of the medium flow. The reflecting column 4 is provided inside the housing 1 and corresponds to the position of the first positioning hole 2. Taking the position of the first positioning hole 2 as the top of the housing 1 as an example, the reflecting column 4 is fixedly installed at the bottom of the inner wall of the housing 1.

[0036] In addition, the housing 1 is made of a heat-resistant and corrosion-resistant material. In this embodiment, the housing 1 is made of heat-resistant polyethylene material, and no scale will be generated on the inner wall of the pipe section, which will not affect the signal transmission of the heat meter and the measurement accuracy is higher. A metal insert 5 is provided inside the wall thickness of the housing 1. The metal insert 5 and the housing 1 are made by an integral molding method, and the metal insert 5 is directly formed inside the wall thickness of the housing 1; the metal insert 5 is mainly installed at the positions of two ultrasonic sensors. And, an ultrasonic sensor mounting seat 6 and a temperature sensor mounting seat 7 are provided on the metal insert 5 to mount the ultrasonic sensor and the temperature sensor. At the same time, the metal insert 5 also serves as a fixing structure for the reflecting column 4 to fix the reflecting column 4. Compared with the conventional metal ultrasonic heat meter base meter, the reflecting column 4 of the present application is made of a heat-resistant and corrosion-resistant material, and the reflecting column 4 cannot be welded and fixed to the housing 1. Therefore, a reserved hole 8 is opened at the bottom of the housing 1, and the depth of the reserved hole 8 is opened to the metal insert 5 inside the wall thickness of the housing 1, and a limiting groove 9 is opened on the metal insert 5. The reflecting column 4 is inserted into the limiting groove 9 through the reserved hole 8 and fixed. The reflecting column 4 and the metal insert 5 can be fixed by a welding method or other methods.

[0037] In a further embodiment, in order to prevent water leakage between the housing 1 and the metal insert 5, an O-ring 10 is provided between the ultrasonic sensor mounting seat and the hole wall of the ultrasonic mounting hole of the housing 1.

[0038] Seal between the housing 1 and the metal insert 5.

[0039] Even further, the metal insert 5 includes two annular pipes 51. The ultrasonic sensor mounting seat 6 is fixedly connected to the annular pipe 51. The temperature sensor mounting seat 7 is fixed to one side of one of the annular pipes 51. The two annular pipes 51 are placed inside the housing 1, and the ultrasonic sensor mounting seat 6 corresponds to the first positioning hole 2, and the temperature sensor mounting seat 7 corresponds to the second positioning hole 3;

[0040] The two annular pipes 51 are connected and fixed by a plurality of connecting ribs 52 distributed in a circumferential array. A connecting port 53 is formed by arranging intervals between adjacent two connecting ribs 52.

[0041] The specific structure of the metal insert 5 is two annular pipes, which are respectively arranged at the positions of two ultrasonic sensors for installing the ultrasonic sensors;

[0042] In addition, in order to improve the tightness of the connection between the metal insert 5 and the housing 1, connection ribs 52 are provided between the two annular pipes 51. The two ends of the connection ribs 52 are connected to the two annular pipes 51. The connection ribs 52 and the annular pipes 51 are integrally formed. The connection ribs 52 are circumferentially and arrayed between the annular pipes 51 and are spaced between adjacent connection ribs 52, and connection ports 53 are formed at the gaps. During the integral molding process of the housing 1 and the metal insert 5, the housing 1 can be integrally formed inside and outside the connection ports 53;

[0043] Meanwhile, in order to further improve the tightness of the connection, stepped notches 54 are provided at the ends of the annular pipes 51.

[0044] Stepped notch 54 structures are provided at the outer ends of the two annular pipes 51. During the integral molding process with the housing 1, an interlaced tooth-like structure is formed between the housing 1 and the annular pipes 51, increasing the tightness and stability of the connection;

[0045] An inwardly recessed annular groove 55 can also be provided on the outer sidewall of the annular pipe 51.

[0046] The annular groove 55 is recessed towards the inside of the pipe. During the integral molding process with the housing 1, a snap ring is formed by the housing 1 in the annular groove 55 and is stuck in the groove.

[0047] A medium flow direction indicator 11 is provided on the outer sidewall of the housing 1.

[0048] Providing the medium flow direction indicator 11 on the outer sidewall of the housing 1 can prompt the user of the installation direction during installation and the medium flow direction in the pipe section.

[0049] In a further embodiment, the two ends of the housing 1 are provided with smooth socket structures 12, which can be electrofusion or hot melt socket welded to heat-resistant polyethylene pipes and pipe fittings.

[0050] Setting the two ends of the pipe section housing 1 as socket structures 12 can be electrofusion or hot melt socket welded to heat-resistant polyethylene pipes and pipe fittings, and the sealing effect is better.

[0051] All the above components can be produced by molds, with higher production efficiency and lower costs.

[0052] The above several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be elaborated in some embodiments.

[0053] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be regarded as falling within the scope described in this specification.

[0054] 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 belong to the protection scope of this application. Therefore, the protection scope of the patent of this application shall be subject to the appended claims.
