Embodiment 1

[0037] see Figure 1-3 As shown, there is no anti-freezing device for energy consumption instruments, including:

[0038] medium line 7,

[0039] The instrument body 2 has a cavity 8 and at least two drainage tubes 3 draining from the cavity 8, the cavity 8 communicates with the medium pipeline 7,

[0040] Wherein, the outer side of the medium pipeline 7 is covered with a heat-absorbing sleeve 9 , and the heat-absorbing sleeve 9 is connected to the drainage tube 3 through a heat-conducting element 11 . The medium pipeline 7 is made of metal material, such as iron, stainless steel, copper, gold, silver, etc. The present invention absorbs the heat of the flowing medium in the medium pipeline 7 through the heat-absorbing sleeve 9, and uses the heat conduction element 11 to transfer the heat to the existing freezing point. Condensation risk of drainage tube 3, so as to solve the problem of freezing risk of drainage tube 3 in low temperature environment, through this design, no n...

Embodiment 2

[0046] see Figure 1-3 As shown, there is no anti-freezing device for energy consumption instruments, including:

[0047] medium line 7,

[0048] The instrument body 2 has a cavity 8 and at least two drainage tubes 3 draining from the cavity 8, the cavity 8 communicates with the medium pipeline 7,

[0049] The insulation cover 4 is connected with the instrument main body 2 and the medium pipeline 7 to form a closed space for the drainage tube 3,

[0050] The heat preservation cover 13 is sealed and connected with the medium pipeline 7 to form a closed space for accommodating the instrument body 2 and the heat preservation cover 4. One side of the heat preservation cover 13 has a light-transmitting element 14,

[0051] Among them, the outer side of the medium pipeline 7 is covered with a heat-absorbing sleeve 9, and the heat-absorbing sleeve 9 is connected to the drainage tube 3 through a heat-conducting element 11, and the heat-conducting element 11 passes through the heat p...

Embodiment 3

[0057] In this embodiment, on the basis of the technical solution in Embodiment 2, the non-energy consumption meter anti-freezing device is further improved, see Figure 4 As shown, a heat-conducting connecting piece 15 is connected between the heat-conducting wires 12 on the two drainage tubes 3, and the heat-conducting connecting piece 15 is a heat-conducting metal. The temperature of the medium fluid in the drainage tube 3 is close, which further ensures that the temperature of the medium fluid in the drainage tube 3 is consistent with the temperature of the medium in the medium pipeline 7, thereby improving data accuracy.

Abstract

The invention discloses a non-energy-consumption instrument anti-freezing device, and belongs to the technical field of metering instruments. The non-energy-consumption instrument anti-freezing device comprises a medium pipeline and an instrument main body, wherein the instrument main body is provided with a cavity and at least two drainage pipes which are arranged in the cavity for drainage, the cavity is in communication with the medium pipeline, a heat absorption sleeve pipe wraps around the outer side of the medium pipeline, and the heat absorption sleeve pipe is connected to the drainage pipes through heat conduction elements. According to the non-energy-consumption instrument anti-freezing device, the problem of condensation or solidification of fluid in the drainage pipes can be solved, the energy consumption is low, the construction cost is low, the maintenance cost low, and meanwhile, the metering precision of the metering instrument is improved.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, and in particular relates to a non-energy-consuming instrument anti-freezing device. Background technique [0002] In the petrochemical industry and thermal power industry, it is often necessary to transport oil, steam and other fluids over long distances. In order to monitor the flow, pressure, temperature and other parameters in the pipeline, corresponding measuring instruments are required for data measurement and control. In order to ensure that the fluid in the drainage tube of the corresponding meter has the same physical properties as the fluid in the pipeline, it is often necessary to protect the meter. [0003] In northern China, the outdoor temperature is often below minus 25°C in winter, and the fluid in the pipeline can be transported normally under the protection of the outer insulation layer. However, in order to facilitate the observation of values, the measuring inst...
