Description

Technical Field

[0001] This utility model relates to the field of electrode installation technology, and in particular to an electrode device installed on a pipeline and insulated from the metal pipe wall. Background Technology

[0002] Electrodes inside metal pipes are special electrode devices used in piping systems. They are usually in direct contact with the medium inside the pipe and are used to measure, monitor, or control the electrochemical properties of the fluid inside the pipe (such as corrosion, pH value, conductivity, etc.).

[0003] Most existing electrodes installed on metal pipe walls are circular, with holes directly drilled to install the electrodes onto the composite pipe wall lined with PTFE insulating tubing. Precision nuts are used to tighten the electrodes for insulation and pressure resistance. However, the following problems still exist when installing electrode devices:

[0004] 1. Circular electrodes are not suitable as oscillator electrodes for radiating microwave signals. Furthermore, the electrodes cannot make good contact with the inner wall of the tube, which can easily cause scaling and blockage on the tube wall. Protruding electrodes are also prone to wear.

[0005] 2. Because it is difficult to cut grooves inside the pipe, the compatibility of electrode devices of different shapes inside the pipe is low, and the sealing performance is also poor. Utility Model Content

[0006] The purpose of this invention is to provide an electrode device that is installed in a pipe and insulated from the metal pipe wall, thereby solving the problems mentioned above.

[0007] To achieve the above objectives, an electrode device is provided that is installed in a pipe and insulated from the metal pipe wall. The device includes a metal pipe, an electrode mounting tube on the outer periphery of the metal pipe, a fixing nut threaded onto the electrode mounting tube, the electrode mounting tube being slidably connected to the metal pipe, and an electrode device fixedly connected to its inner end. The metal pipe has a through hole, a support member is provided within the through hole, a rubber pad is provided on the support member, and the support member is slidably connected to the through hole. A sealing ring is provided on the inner wall of the metal pipe inside the through hole, an installation groove is provided inside the sealing ring, an installation hole is provided in the installation groove, and a sealing short tube is provided outside the sealing ring. The sealing short tube is connected to the installation hole and slidably connected to the support member.

[0008] According to the electrode device installed on a pipe and insulated from the metal pipe wall, there are several through holes arranged in a ring, and the support member corresponds to each through hole.

[0009] According to the electrode device installed in a pipeline and insulated from the metal pipe wall, the electrode mounting tube is slidably connected to the through hole, and there is a one-to-one correspondence between the through hole and the electrode mounting tube.

[0010] According to the electrode device installed in a pipe and insulated from the metal pipe wall, the support member has the same shape as the through hole and is made of ceramic.

[0011] According to the electrode device installed on a pipe and insulated from the metal pipe wall, both the sealing ring and the sealing short tube are made of rubber and are integrally injection molded.

[0012] According to the electrode device installed on a pipeline and insulated from the metal pipe wall, the number of mounting grooves, mounting holes and sealing short tubes on the sealing ring is the same as the number of through holes.

[0013] According to the electrode device installed in a pipeline and insulated from the metal pipe wall, the electrode device is adapted to the mounting groove and the lower end is flush with the inner side of the sealing ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with the existing technology, by providing a through hole in the metal pipe and connecting a support member in the through hole, and providing a sealing ring on the inner side of the metal pipe, the electrode device is located in the sealing ring during installation. The embedded design allows the electrode to be a rectangular oscillator suitable for radiating microwave signals. The electrode is conformal to the pipe wall and has no protruding parts on the inner wall of the pipe, overcoming the disadvantages of circular electrodes being prone to scaling, clogging, and wear.

[0016] 2. Compared with the existing technology, by providing a sealing short tube on the sealing ring, the sealing short tube is located inside the through hole and used in conjunction with the sealing ring, which improves the overall sealing performance of the electrode. At the same time, under the action of the support, it ensures that the electrode is completely isolated from the metal tube wall, avoiding current leakage or electromagnetic interference and improving its safety. In addition, the sealing ring is made of rubber, which makes it easy to groove on its inner side to suit electrode devices of different shapes, and has good adaptability. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5 This utility model embodiment discloses an electrode device installed on a pipe and insulated from the metal pipe wall. It includes a metal pipe 1, an electrode mounting tube 2 provided on the outer periphery of the metal pipe 1, the electrode mounting tube 2 being cylindrical in shape, the electrode mounting tube 2 being slidably connected to a through hole 11 and corresponding one-to-one with the through hole 11, a fixing nut 3 being threadedly connected to the electrode mounting tube 2, the electrode mounting tube 2 being slidably connected to the metal pipe 1, and an electrode device 4 being fixedly connected to its inner end. After the electrode is installed, the electrode mounting tube 2 located on the outside of the metal pipe 1 is fixed by the fixing nut 3.

[0027] The metal pipe 1 is provided with through holes 11, and a support member 5 is provided inside the through holes 11. There are several through holes 11, which are arranged in a ring. The support member 5 corresponds to each through hole 11. The shape of the support member 5 is the same as that of the through hole 11, and the material is ceramic. The support member 5 is provided with a rubber pad 51 and is slidably connected to the through hole 11. Under the action of the ceramic support member 5, the electrode is completely isolated from the metal pipe wall to avoid current leakage or electromagnetic interference. At the same time, under the action of the rubber pad 51, the support member 5 is prevented from directly contacting the metal pipe 1, and it can protect it.

[0028] A sealing ring 6 is provided on the inner wall of the metal pipe 1 located inside the through hole 11. An installation groove 61 is provided inside the sealing ring 6, and an installation hole 62 is provided inside the installation groove 61. A sealing short tube 63 is provided outside the sealing ring 6. Under the action of the sealing ring 6, the electrode can be further ensured to be completely isolated from the metal pipe wall, improving safety. At the same time, under the action of the sealing ring 6, the sealing performance at the through hole 11 can be improved. The number of installation grooves 61, installation holes 62 and sealing short tubes 63 on the sealing ring 6 is the same as that of the through hole 11. The sealing short tube 63 is connected to the installation hole 62 and is slidably connected to the support 5. The sealing ring 6 and the sealing short tube 63 are both made of rubber and are integrally injection molded. The electrode device 4 is adapted to the installation groove 61, and its lower end is flush with the inner side of the sealing ring 6. The present invention adopts an embedded design. The electrode can be a rectangular oscillator suitable for radiating microwave signals. The electrode is conformal to the inner wall of the pipe and there is no protruding part. It overcomes the disadvantages of circular electrodes being prone to scaling, clogging and wear.

[0029] Working principle: During installation, first install the sealing ring 6 inside the metal pipe 1, and the sealing short tube 63 corresponds one-to-one with the through hole 11. Then, install the support 5 from the inside of the metal pipe 1 into the through hole 11. At this time, under the action of the sealing short tube 63, it is supported to prevent it from falling. Then, the electrode mounting tube 2 with the electrode device 4 passes through the sealing short tube 63 and the support 5 from the inside of the sealing ring 6, so that the electrode device 4 is located in the mounting groove 61. Finally, the electrode mounting tube 2 located on the outside of the metal pipe 1 is fixed by the fixing nut 3 to complete the installation.

[0030] During installation, the ceramic support 5 ensures complete isolation between the electrode and the metal pipe wall, preventing current leakage or electromagnetic interference. Simultaneously, the rubber pad 51 prevents direct contact between the support 5 and the metal pipe 1, providing protection. The sealing ring 6 further ensures complete isolation between the electrode and the metal pipe wall, enhancing safety. The sealing ring 6 also improves the sealing performance at the through-hole 11. Furthermore, the invention employs an embedded design, allowing the electrode to be a rectangular vibrator suitable for radiating microwave signals. The electrode conforms to the pipe wall without any protruding parts, overcoming the drawbacks of circular electrodes such as easy scaling, clogging, and wear.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
