Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline parameter monitoring, in particular to a pipeline temperature and pressure integrated information acquisition device. BACKGROUND

[0002] In the field of pipeline parameter monitoring, it is crucial to monitor the operation status of pipelines in places such as machine rooms, and obtaining the temperature and pressure parameters of the pipelines helps to ensure the safe and stable operation of the entire system.

[0003] Currently, the monitoring of pipeline temperature and pressure in machine rooms generally adopts the mode of independently installing mechanical thermometers, mechanical pressure gauges, temperature sensors, and pressure sensors, etc. This mode is to install various monitoring components on the pipeline to obtain temperature and pressure data. In order to install these components, hole opening operations need to be performed on the pipeline, and the number of holes is relatively large. After installation, the functions and characteristics of each component are relied on to realize separate measurement of pipeline temperature and pressure.

[0004] However, the mode of independently installing monitoring components requires a large number of holes to be opened on the pipeline, and a large number of holes are opened on a single pipeline, which is prone to generate a large amount of welding slag during the hole opening process, and there is a risk of residual welding slag. If the welding slag is not completely cleaned, it is easy to cause pipeline blockage, which seriously affects the efficiency of fluid transportation. At the same time, the numerous welding sites become potential leakage points of the system, increasing the maintenance cost in the later period. CONTENT OF THE INVENTION

[0005] In order to reduce the adverse risks caused by excessive hole opening on the pipeline, the present application provides a pipeline temperature and pressure integrated information acquisition device.

[0006] The present application provides a pipeline temperature and pressure integrated information acquisition device, which adopts the following technical solution:

[0007] A pipeline temperature and pressure integrated information acquisition device, comprising: a base pipe seat, and a temperature detection component and a pressure detection component installed on the base pipe seat; one end of the base pipe seat is connected to a pipeline to be detected, and the base pipe seat has a fluid passage for simultaneously communicating the pipeline to be detected, the temperature detection component, and the pressure detection component.

[0008] By adopting the above technical solution, the temperature detection component and the pressure detection component are integrated and installed on the base pipe seat, realizing integrated acquisition of temperature and pressure parameters, thereby reducing the number of pipeline holes, reducing the risk of residual welding slag, reducing the possibility of pipeline blockage, improving the efficiency of fluid transportation, and reducing the potential leakage points and maintenance cost of the system in the later period.

[0009] Optionally, the temperature detecting component comprises a sealed cylinder and a temperature detecting element; the sealed cylinder is installed on the base pipe seat and extends into the fluid channel, and the sealed cylinder has an installation cavity for detachably installing the temperature detecting element, and the sealed cylinder separates the fluid channel from the installation cavity by the cylinder wall of the sealed cylinder; the temperature detecting element transmits temperature through the sealed cylinder.

[0010] By using the above technical scheme, the temperature detecting element transmits temperature through the sealed cylinder to separate the temperature detecting element from the detecting fluid, so that the fluid can continuously flow in the pipe to be detected when the temperature detecting element is replaced, thereby improving the convenience of maintenance.

[0011] Optionally, the sealed cylinder extends from one end of the base pipe to the pipe to be detected and extends into the pipe to be detected.

[0012] By using the above technical scheme, the sealed cylinder can more deeply contact the fluid in the pipe, so as to more accurately transmit temperature information and improve the accuracy of temperature detection.

[0013] Optionally, the sealed cylinder is detachably connected to the base pipe seat.

[0014] By using the above technical scheme, the sealed cylinder and the base pipe seat can be easily assembled.

[0015] Optionally, the pressure detecting component comprises a shut-off valve and a pressure detecting element, and the shut-off valve is connected between the pressure detecting element and the base pipe seat to communicate or separate the pressure detecting element from the base pipe seat.

[0016] By using the above technical scheme, the shut-off valve can communicate or separate the channel between the pressure detecting element and the base pipe seat, so that the connection between the pressure detecting element and the pipe can be conveniently cut off when needed, thereby facilitating the calibration, replacement or maintenance of the pressure detecting element and improving the safety of the device.

[0017] Optionally, a connecting pipe is detachably connected between the pressure detecting element and the shut-off valve.

[0018] By using the above technical scheme, the detachable connection of the pressure detecting element relative to the connecting pipe improves the convenience of replacement and maintenance of the pressure detecting element.

[0019] Optionally, a support is arranged on the connecting pipe, and the support can be supported between the connecting pipe and the pipe to be detected when the base pipe seat is installed on the pipe to be detected.

[0020] By adopting the technical scheme, when the base pipe seat is installed on the to-be-inspected pipeline, the support member can be supported between the connecting pipe and the to-be-inspected pipeline, the stability of the connecting pipe is enhanced, and the risk of instability of the pressure detection element caused by loosening or damage of the connecting pipe due to vibration or external force is reduced.

[0021] Optionally, the support member comprises a support base and a support rod, the support base is connected to the connecting pipe, and the support rod is threadedly moved in the support base and abuts against the outer wall of the to-be-inspected pipeline.

[0022] By adopting the technical scheme, the support rod is threadedly moved in the support base and abuts against the outer wall of the to-be-inspected pipeline, so that the total length of the support base and the support rod can be flexibly adjusted according to the actual size and installation position of the pipeline.

[0023] Optionally, the support rod has a clearance hole, and the support member further comprises a cable tie, the cable tie passes through the support rod through the clearance hole and tightly clamps the to-be-inspected pipeline.

[0024] By adopting the technical scheme, the connection stability between the support member and the pipeline is further enhanced, and the rotation of the support member on the pipeline is prevented.

[0025] In summary, the present application has at least one of the following beneficial effects:

[0026] 1. By integrating the temperature detection assembly and the pressure detection assembly on the base pipe seat, the number of openings on the to-be-inspected pipeline is reduced, so that the adverse risks caused by too many openings on the pipeline can be reduced;

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] Example 1:

[0036] This application discloses an integrated pipeline temperature and pressure information acquisition device. (Refer to...) Figure 1 The integrated pipeline temperature and pressure information acquisition device includes a base pipe seat 1, a temperature detection component 2, and a pressure detection component 3. The base pipe seat 1 is installed on the pipeline 8 to be inspected, and both the temperature detection component 2 and the pressure detection component 3 are installed on the base pipe seat 1.

[0037] Reference Figure 1 and Figure 2 Among them, the base pipe seat 1 is a T-shaped three-way pipe with a first end 11, a second end 12 and a third end 13. The first end 11 and the second end 12 are coaxially distributed along a straight line, and the third end 13 is located between the first end 11 and the second end 12. The inner cavity of the base pipe seat 1 is a fluid channel that connects the first end 11, the second end 12 and the third end 13 simultaneously.

[0038] The first end 11 is installed onto the pipe 8 to be inspected by welding or by flange bolts, such that the distribution square of the first end 11 and the second end 12 is perpendicular to the axis of the pipe, while simultaneously connecting the fluid passage to the pipe 8 to be inspected. The second end 12 is used to install the temperature detection component 2, and the third end 13 is used to install the pressure detection component 3.

[0039] Reference Figure 1 and Figure 2For the temperature detection component 2, the temperature detection component 2 includes a sealed cylinder 21 and a temperature detection element 22. The sealed cylinder 21 includes a temperature sensing section 211, a locking section 212, and a blocking section 213 that are coaxially fixedly connected in sequence. The temperature sensing section 211 is cylindrical with an outer diameter smaller than the inner diameter of the fluid channel. The axial extension length of the temperature sensing section 211 is greater than the axial extension length of the base pipe seat 1 along the first end 11 and the second end 12. At the same time, the end of the temperature sensing section 211 away from the locking section 212 is sealed, and the temperature sensing section 211 is made of a metal with good thermal conductivity and corrosion resistance, such as copper or stainless steel. The locking section 212 and the blocking section 213 are both cylindrical with hollow interiors and open ends. The outer diameter of the blocking section 213 is greater than the outer diameter of the locking section 212. The locking section 212 has an external thread on its outer periphery, and the outer diameter of the locking section 212 is equivalent to the inner diameter of the second end 12. The inner periphery of the second end 12 has an internal thread that matches the outer periphery of the locking section 212. The inner cavities of the temperature sensing section 211, the locking section 212, and the blocking section 213 together form a mounting cavity 4 for mounting the temperature sensing element 22.

[0040] When the sealed cylinder 21 is installed onto the base pipe seat 1, the temperature sensing section 211 coaxially passes through the first end 11 and the second end 12, while the locking section 212 is coaxially threaded into the second end 12. The blocking section 213 faces the end face of the second end 12 to limit the over-installation of the sealed cylinder 21. It should be noted that after the sealed cylinder 21 is installed, the locking section 212 seals the end of the second end 12, and the gap between the outer wall of the temperature sensing section 211 and the inner wall of the base pipe seat 1 communicates with the third end 13 to allow fluid to pass through. The end of the temperature sensing section 211 away from the locking section 212 extends out of the first end 11 into the pipe to be inspected, thereby enhancing the ability of the temperature sensing section 211 to receive fluid temperature.

[0041] Reference Figure 2 and Figure 3 The temperature sensing element 22 is a thermometer with a temperature display dial 221 and a probe 222. The probe 222 is inserted into the inner cavity of the temperature sensing section 211 along the distribution direction of the locking section 212 and the temperature sensing section 211, and abuts against the inner wall of the temperature sensing section 211 to receive the temperature transmitted by the temperature sensing section 211 and to display the temperature on the temperature display dial 221. A mounting head 223 is fitted on the outer wall of the end of the probe 222 near the dial. The mounting head 223 has external threads on its outer circumference. The inner circumference of the locking section 212 has external threads that are adapted to the outer circumference of the mounting head 223. The thermometer is connected to the locking section 212 through the mounting head 223 to be installed on the sealed cylinder 21.

[0042] It should be noted that when the temperature sensing element 22 needs to be replaced, since the locking section 212 blocks the end of the second end 12, it is not necessary to shut off the fluid flow in the pipe 8 to be tested. Simply remove the threads of the temperature sensing element 22 and replace it with a new one.

[0043] ReferenceFigure 1 and Figure 2 For the pressure detection assembly 3, the pressure detection assembly 3 includes a shut-off valve 31, a pressure detection element 32, and a connecting pipe 33. The shut-off valve 31 is a valve that controls the flow of fluid, and can be a ball valve, gate valve, or other valve. The two ends of the shut-off valve 31 relative to the valve core are connectors 7. One connector 7 of the shut-off valve 31 is threaded onto the third end 13 of the base pipe seat 1, and the other connector 7 of the shut-off valve 31 is threaded onto the connecting pipe 33. The connecting pipe 33 is L-shaped, and its inlet end is threaded to the connector 7, with the axis of the inlet end parallel to the axis of the pipe 8 to be inspected. The pressure detection element 32 is a pressure gauge, and the outlet end of the connecting pipe 33 is threaded onto the detection end of the pressure gauge, thus connecting the pressure gauge to the shut-off valve 31 via the connecting pipe 33. It should be noted that after the connecting pipe 33 is installed, its outlet end extends away from the pipe 8 to be inspected relative to its inlet end.

[0044] During testing, the shut-off valve 31 is in the open position, allowing fluid to flow from the pipeline under test 8 through the base pipe seat 1, the shut-off valve 31, and the connecting pipe 33 to the pressure gauge. When the pressure gauge needs to be replaced, the shut-off valve 31 is closed, which prevents fluid from continuing to flow into the connecting pipe 33, thus allowing the pressure gauge to be replaced.

[0045] The implementation principle of the integrated pipeline temperature and pressure information acquisition device in this application embodiment is as follows: the fluid in the pipeline 8 to be inspected enters the base pipe seat 1 from the first end 11, and then passes through the third end 13, the shut-off valve 31 and the connecting pipe 33 in sequence to act on the pressure detection element 32 for pressure detection. The temperature sensing end of the sealed cylinder 21 extends into the pipeline 8 to be inspected through the first end 11 to transfer the fluid temperature to the thermometer.

[0046] Example 2:

[0047] The difference between this embodiment and Embodiment 1 is that a support member 5 is installed on the connecting pipe 33.

[0048] Specifically, refer to Figure 4 and Figure 5 The support 5 is sleeved on the connecting pipe 33 and is used to support the connecting pipe 33 and the pipe to be inspected 8 to improve the stability of the device.

[0049] Specifically, the support member 5 includes a support base 51, a support rod 52, and a cable tie 53. The support base 51 is slidably sleeved on the end of the connecting pipe 33 near the shut-off valve 31 and can rotate relative to the connecting pipe 33. The inner circumference of the support base 51 sleeved on the connecting pipe 33 has a rubber layer that contacts the outer wall of the connecting pipe 33 to enhance the friction between the support base 51 and the connecting pipe 33. When the connecting pipe 33 is separated from the shut-off valve 31, the support base 51 can be separated from the end of the connecting pipe 33. The support rod 52 is threadedly moved within the support seat 51, with one end extending out of the support seat 51. As the support rod 52 moves away from the support seat 51, it simultaneously moves towards the pipe to be inspected 8, so that the end of the support rod 52 away from the support seat 51 can abut against the outer wall of the pipe to be inspected 8, thereby supporting the connecting pipe 33, and further supporting the pressure detection element 32 and the shut-off valve 31. This ensures that both ends of the shut-off valve 31 are supported by the support rod 52 and the base pipe seat 1, thus providing two support points between the information acquisition device and the pipe to be inspected 8, thereby improving the overall stability of the device.

[0050] The end of the support rod 52 furthest from the support base 51 has a clearance hole 6 that passes through both sides of the support rod 52. A cable tie 53 can pass through the clearance hole 6 and is serrated (not shown in the figure). After the support rod 52 abuts against the pipe 8 to be inspected, the cable tie 53 is passed through the support hole to simultaneously enclose the pipe. Then, one end of the cable tie 53 is passed through the buckle of the cable tie 53, so that the cable tie 53 tightens the support rod 52 and the pipe 8 to be inspected. The serrations of the cable tie 53 prevent the cable tie 53 from loosening. After the cable tie 53 tightens the support rod 52 and the pipe 8 to be inspected, it prevents the support rod 52 from rotating due to vibration, thus improving the stability of the support component 5. Simultaneously, when the data acquisition device is located below the pipe 8 to be inspected, the cable tie 53 can hold the support rod 52 and the support base 51, improving the stability of the device.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
