Description

Technical Field

[0001] The utility model relates to the technical field of flow probes, in particular to a flow probe which is leak-proof during installation. Background Art

[0002] A flow probe is a device used to measure the flow of fluids (including liquids and gases). Its core function is to convert fluid flow into electrical signals for subsequent digital processing and data transmission. The working principles of flow probes are mainly based on two principles: one is based on the principle of measuring force. When the fluid passes through the probe, it will generate force on the probe, causing the probe to be slightly deflected. The magnitude of the deflection is proportional to the fluid flow rate. By measuring the amount of deflection or the magnitude of the force, the flow rate can be determined. The other is based on the principle of measuring pressure difference or heat exchange. The flow state of the fluid medium is reflected by monitoring the deviation changes of the thermistor inside the probe. As an important part of the flow measurement system, it is widely used in industry, agriculture, medical care and other fields.

[0003] At present, the existing flow probes are generally installed on the measuring pipe through flanges, gaskets and other parts when in use. During the installation of the flow probe, due to improper installation or poor sealing, leakage problems often occur, resulting in measurement errors and even safety accidents. Therefore, it is of great significance to develop a flow probe that prevents installation leakage. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a flow probe that prevents installation leakage to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flow probe with anti-installation leakage, comprising a flow probe body and a pipeline, the flow probe body is installed inside the pipeline, and an installation mechanism connected to the pipeline is arranged on the outside of the flow probe body, the installation mechanism comprises a transverse plate and a torsion spring, a transverse plate is sleeved on the outside of the flow probe body, a rotating frame is rotatably connected inside the transverse plate, a support block is arranged at one end of the rotating frame, a mounting plate is arranged at one end of the support block, and an installation frame is arranged at the top of the pipeline.

[0006] Preferably, a torsion spring is connected between the support block and the transverse plate, and the support block and the transverse plate form an elastic structure through the torsion spring.

[0007] Preferably, the support block and the pipeline form a snap-fit ​​structure through a mounting plate and a mounting frame, and two mounting plates and two mounting frames are symmetrically arranged about the central axis of the flow probe body.

[0008] Preferably, the mounting plate is configured as an inverted "T"-shaped structure, and the rotating frame and the supporting block are combined to form a W-shaped structure.

[0009] Preferably, an anti-leakage mechanism is arranged on the outer side of the flow probe body, and the anti-leakage mechanism is composed of a sealing ring, a No. 1 airbag, an extrusion plate, a No. 2 airbag, a catheter and a support plate.

[0010] Preferably, a support plate is provided on the outside of the flow probe body, an extrusion plate is provided at the bottom end of the support plate, a No. 1 airbag is provided at the bottom end of the extrusion plate, a No. 2 airbag is provided at the bottom end of the support plate and located on the inner side of the extrusion plate, and a catheter is connected between the No. 1 airbag and the No. 2 airbag.

[0011] Preferably, a sealing ring is provided on the outer side of the flow probe body below the No. 1 airbag, and the sealing ring is made of rubber material.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. During the installation process, the existing flow probes often have leakage problems due to improper installation or poor sealing, which leads to measurement errors and even safety accidents. The utility model is provided with an anti-leakage mechanism. Since the No. 2 airbag is connected to the No. 1 airbag, and the outer surface of the flow probe body is provided with a sealing ring, after the flow probe body is installed in the pipeline, the No. 1 airbag can be squeezed by the squeezing plate, so that its surface is in close contact with the pipeline and the flow probe body. At the same time, the excess gas is sent into the No. 2 airbag through the conduit, so that the outer surface of the No. 2 airbag is in close contact with the squeezing plate, the No. 1 airbag, and the flow probe body. Therefore, the cooperation of the sealing ring, the No. 1 airbag, and the No. 2 airbag can achieve multiple sealing effects between the flow probe body and the pipeline, thereby effectively preventing leakage problems during the installation process and improving the accuracy and safety of the measurement.

[0014] 2. Existing flow probes are generally installed on the measuring pipe through flanges, sealing gaskets and other parts, which makes the installation process inconvenient. The utility model is provided with a mounting mechanism. Since the support block and the cross plate are elastically connected by a torsion spring, the mounting plate can be rotated 90° by rotating the rotating frame. After the flow probe body is placed at the specified position of the pipeline, the mounting plate is located in the mounting frame. After the rotating frame is loosened, the rotating frame and the mounting plate will be reset under the action of the torsion spring and can be clamped with the mounting frame, thereby facilitating the rapid installation of the flow probe body in the pipeline and installing it firmly.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It can be seen that since the support block 304 and the cross plate 301 are elastically connected by the torsion spring 303, the mounting plate 305 can be rotated 90° by rotating the rotating frame 302. After the flow probe body 1 is placed at the specified position of the pipeline 2, the mounting plate 305 is located in the mounting frame 306. After the rotating frame 302 is released, the rotating frame 302 and the mounting plate 305 will be reset under the action of the torsion spring 303 and snap-fitted with the mounting frame 306, thereby facilitating the rapid installation of the flow probe body 1 in the pipeline 2 and installing it firmly.

In this process, the extrusion plate 4 03 squeeze the No. 1 airbag 402 so that its surface is in close contact with the pipeline 2 and the flow probe body 1, and at the same time, send excess gas into the No. 2 airbag 404 through the conduit 405, so that the outer surface of the No. 2 airbag 404 is in close contact with the extrusion plate 403, the No. 1 airbag 402, and the flow probe body 1, so that the multiple sealing effects between the flow probe body 1 and the pipeline 2 can be achieved through the cooperation of the sealing ring 401, the No. 1 airbag 402, and the No. 2 airbag 404, so as to effectively prevent leakage problems during the installation process.
