Description

Technical Field

[0001] This utility model relates to the field of flow channel technology, and in particular to a flow channel for sensor insertion installation. Background Technology

[0002] In various systems involving fluid parameter monitoring, such as chemical industry, biopharmaceutical, and environmental water treatment, sensors are often used to obtain information such as fluid temperature, pressure, flow rate, and composition in real time. In order for the sensor to accurately sense the fluid parameters, the sensor is usually inserted into a flow channel, allowing the fluid to flow in the flow channel and make full contact with the sensor.

[0003] Currently, the common method for installing sensors is to directly connect the sensor's surface threads to the flow channel. However, this method has a significant drawback: during installation, when the sensor is rotated to screw its threads into the flow channel, the sensor cable rotates along with the sensor. Since the cable is usually made of multiple strands of wire and has a certain degree of flexibility and is relatively long, frequent rotation can easily cause the cable to twist. Cable twisting not only affects the stability of sensor signal transmission, but long-term twisting may also cause the internal wires of the cable to break and the insulation layer to be damaged, thereby causing sensor failure and affecting the normal operation of the entire monitoring system.

[0004] To address this, a flow channel for sensor insertion installation is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a flow channel for sensor insertion installation, which solves the problem that the common sensor installation method uses the threads on the sensor surface to directly connect to the flow channel. However, this installation method has obvious drawbacks: during installation, when the sensor is rotated to screw its threads into the flow channel, the sensor cable will rotate along with the sensor. Since the cable is usually made of multiple strands of wire and has a certain degree of flexibility and is relatively long, frequent rotation can easily cause the cable to twist. Cable twisting not only affects the stability of sensor signal transmission, but long-term twisting may also cause the internal wires of the cable to break and the insulation layer to be damaged, thereby causing sensor failure and affecting the normal operation of the entire monitoring system.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flow channel for sensor insertion installation, comprising a flow channel body, a sensor body inserted into the flow channel body, and a locking nut one threadedly connected to the surface of the sensor body, a locking nut two threadedly connected to the upper end of the surface of the flow channel body, a water inlet fixedly connected to the lower end of the flow channel body, and a water outlet fixedly connected to the upper side of the flow channel body.

[0007] Preferably, the inner wall of the locking nut is provided with an internal thread and is threadedly connected to the external thread of the sensor body. The locking nut is installed at the upper port inside the flow channel body.

[0008] Preferably, a stop portion is provided at the upper end of one surface of the locking nut, and the lower end face of the stop portion is in close contact with the inner upper port of the flow channel body, and the stop portion and the locking nut are integrally formed.

[0009] Preferably, the upper end of the locking nut is provided with a pressing part, and the pressing part is in close contact with the side of the stop part, and the pressing part is integrally formed with the locking nut.

[0010] Preferably, a sealing ring is fitted onto the surface of the locking nut, and the side of the sealing ring closest to the stop and the main body of the flow groove is in close contact with both.

[0011] Preferably, both locking nut one and locking nut two have textured surfaces, and the textures are distributed in a ring shape.

[0012] Preferably, the upper end of the surface of the main body of the flow channel is provided with an external thread, and the locking nut 2 is threadedly connected to the main body of the flow channel through the external thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This application provides two locking nuts: a first locking nut and a second locking nut. The first locking nut is screwed into the threaded surface of the sensor body, and the second locking nut is fitted onto the surface of the sensor body. The second locking nut is threadedly connected to the flow channel body. This allows the sensor body to be fixedly installed simply by engaging the threaded connection between the second locking nut and the flow channel body, without needing to rotate the sensor body. This effectively solves the problem of easy cable twisting during traditional sensor installation and ensures the stability and reliability of sensor signal transmission. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution:

[0023] A flow channel for sensor insertion installation includes a flow channel body 1, a sensor body 2 inserted into the flow channel body 1, and a locking nut 3 threadedly connected to the surface of the sensor body 2. A locking nut 4 is threadedly connected to the upper end of the surface of the flow channel body 1. An inlet 5 is fixedly connected to the lower end of the flow channel body 1, and an outlet 6 is fixedly connected to the upper side of the flow channel body 1.

[0024] In this embodiment: by setting a locking nut 3 and a locking nut 4, the locking nut 3 is screwed into the thread on the surface of the sensor body 2, and the locking nut 4 is fitted onto the surface of the sensor body 2. The locking nut 4 is threadedly connected to the flow channel body 1, so that when the sensor body 2 is inserted into the flow channel body 1, the sensor body 2 can be fixedly installed simply by the thread engagement of the locking nut 4 with the flow channel body 1, without having to rotate the sensor body 2. This effectively solves the problem of easy twisting of cables during traditional sensor installation and ensures the stability and reliability of sensor signal transmission.

[0025] Specifically, such as Figure 2 , Figure 3 As shown, the inner wall of the locking nut 3 is provided with an internal thread, and it is threadedly connected to the external thread of the sensor body 2. The locking nut 3 is installed at the upper port inside the flow channel body 1.

[0026] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a stop portion 7 is provided at the upper end of the surface of the locking nut 3, and the lower end face of the stop portion 7 is in close contact with the upper internal port of the flow channel body 1. The stop portion 7 and the locking nut 3 are integrally formed.

[0027] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the upper end of the locking nut 4 is provided with a pressing part 8, and the side of the pressing part 8 close to the stop part 7 is in close contact with it. The pressing part 8 and the locking nut 4 are integrally formed.

[0028] Specifically, such as Figure 4 As shown, a sealing ring 9 is fitted onto the surface of the locking nut 3, and the side of the sealing ring 9 closest to the stop part 7 and the main body of the flow groove 1 is in close contact with both.

[0029] In this embodiment: the threaded connection between the locking nut 3 and the sensor body 2 enables the initial positioning and fixation of the sensor body 2 within the flow channel body 1, providing a guarantee for subsequent stable installation and ensuring that the sensor body 2 will not easily shift under fluid impact; the stop part 7 and the pressing part 8, when the locking nut 4 is tightened, the pressing part 8 can apply pressure to the stop part 7, thereby further pressing the sensor body 2, enhancing the stability of the sensor body 2 installation, and effectively preventing the sensor body 2 from loosening due to fluid impact and other factors during operation; the sealing ring 9 effectively prevents fluid leakage from the connection between the locking nut 3 and the flow channel body 1, ensuring the normal flow path of the fluid within the flow channel body 1, improving the sealing performance of the device, ensuring the accuracy of fluid monitoring, and also preventing fluid leakage from damaging the surrounding environment and equipment.

[0030] Specifically, such as Figure 2 As shown, both locking nut 3 and locking nut 4 have textured surfaces, and the textures are distributed in a ring shape.

[0031] In this embodiment, the annular texture facilitates the tightening or loosening of the locking nut 3 and the locking nut 4 by the operator, improving the convenience of installation and maintenance.

[0032] Specifically, such as Figure 2 As shown, the upper end of the surface of the flow channel body 1 is provided with an external thread, and the locking nut 2 4 is threadedly connected to the flow channel body 1 through the external thread.

[0033] In this embodiment: by setting a locking nut 2 4 to be threadedly connected to the flow channel body 1 through an external thread, the locking nut 2 4 can be firmly installed on the flow channel body 1. With the cooperation of the locking nut 1 3, the pressing part 8 and the stop part 7, the sensor body 2 is stably fixed, ensuring the reliable operation of the sensor body 2 in the flow channel body 1.

[0034] Working principle: After inserting the sensor body 2 into the flow channel body 1, the sealing ring 9 is fitted onto the locking nut 3, ensuring that the sealing ring 9 is correctly positioned and securely installed. Then, one end of the sensor body 2 passes through the locking nut 4 and the locking nut 3. At this time, the locking nut 3 is screwed into the thread on the surface of the sensor body 2. The locking nut 3 and the sensor body 2 are then inserted into the interior of the flow channel body 1 until the sealing ring 9 and the stop 7 contact the upper inner port of the flow channel body 1. Then, the locking nut 4 is screwed into the flow channel body 1 through the thread engagement with the thread on the upper surface of the flow channel body 1. During the screwing process, the locking nut... The pressure part 8 inside the second 4 gradually approaches and comes into close contact with the stop part 7 on the locking nut 3. As the locking nut 4 is tightened, the pressure part 8 applies pressure to the stop part 7, thereby further pressing the sensor body 2, realizing the insertion and installation of the sensor body 2 and the flow channel body 1. After installation, the fluid to be monitored is introduced into the flow channel body 1 through the inlet 5 and discharged through the outlet 6. The fluid flows in the flow channel body 1 and comes into full contact with the sensor body 2. The sensor body 2 senses various parameters of the fluid in real time and converts them into transmittable signals such as electrical signals, which are transmitted to subsequent signal processing and display equipment through cables to realize the monitoring of fluid parameters.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
