Description

Electrode Holder for Salinity Measurement Device {Holder of electrode pipe for salinometer}

The present invention is installed on a fluid passage such as a distilled water line of a ship or a feedwater and condensate line of a boiler, and the salinity measurement for inserting and detaching an electrode rod measuring the salinity of the fluid into the fluid passage without stopping the flow of the fluid. The present invention relates to an electrode holder for a device, and more particularly, a slider that is slidable together with an electrode in a casing installed through the fluid passage so that the rear end of the electrode can be inserted into and separated from the fluid passage according to the movement of the slider. In case of deviating, the casing is automatically sealed by the slider, thereby minimizing the damage of the electrode generated during the use of the electrode, and periodically performing only the time required to measure the salinity by the electrode. Extend the service life of the electrode At the same time, it completely blocks the leakage of fluid through the electrode holder when repairing or replacing the electrode, improving work efficiency and preventing corrosion or damage of peripheral devices caused by the leakage of fluid. The present invention relates to an electrode holder for a salt measuring device.

In general, the salinity measuring device is a measuring device for measuring salinity (salinity (weight of salt contained in 1 kg of seawater) in seawater or freshwater). In the past, the salinity measurement was performed by directly dehydrating seawater or freshwater, Although salinity was measured using a titration method by aqueous solution, in recent years, the salinity is sensitive to salts by introducing an electrode into seawater or fresh water and using a principle of increasing electrical conductivity. A method of measuring salinity is used by using a potential difference between a working electrode that is sensitively sensitive and a reference electrode that always maintains a constant potential without being sensitive to salinity.

The salinity measuring apparatus as described above is widely used in various industrial fields such as food production factories, various laboratories or laboratories, or salinity measurement of agricultural water, and in particular, in the case of ships, distilled water lines for supplying drinking water of people on board. Since there is a high risk of salinity rise due to the inflow of seawater on the fluid passages such as boiler lines for cooling and heating of cabins, the fluids flowing through the fluid passages by installing salinity measuring devices on such fluid passages. By measuring and managing the salinity of salt from time to time, it is possible to prevent damage to distilled water equipment or boiler facilities and consequently deterioration of living environment of passengers.

As described above, a conventional salinity measuring apparatus installed on a fluid passage such as a distilled water line or a boiler line of a ship is fastened to a boss 25a protruding from a pipe wall of the fluid passage 25, as shown in FIG. An electrode holder is formed as a nipple joint 21 and 22 and a gate valve 20 that moves along a screw surface of the nipple joint 21 and 22 by the rotation of the handle 24. 10 is a gate valve 20 such that the rear side of the body 11 to which the electrode sensor is exposed is introduced into the fluid passage 25, and the front side of the body 11 to which the cable 12 is connected is exposed to the outside. And nipple joints 21 and 22 are inserted and supported.

In addition, the front end of the electrode rod 10 to which the cable 12 is connected between the cable 12 and the inner surface of the electrode rod body 11 to prevent leakage of fluid through the electrode rod body 11. A cable gland 12a having a packing material interposed therebetween is formed, and one side of the gate valve 20 is provided with a sealing ring 23 to prevent leakage of fluid when the gate valve 20 is closed. It is.

In the conventional salinity measuring apparatus as described above, the electrode 10 is inserted through the gate valve 20 and the nipple joints 21 and 22 so that the rear side of the electrode 10 is introduced into the fluid passage 25. Next, when the handle 24 is rotated to close the gate valve 20, the electrode rod 10 is firmly supported on the fluid passage 25 without leakage of fluid and at the same time, the fluid passage is opened through the rear end of the electrode rod 10. (25) The fluid inside is brought into contact with the electrode sensor, so that the salinity value of the fluid measured from the electrode sensor is transmitted through the cable 12 to an indicator (indicator) not shown, so that the administrator It is possible to measure and manage the salts contained in.

However, in the conventional salinity measuring apparatus as described above, when the gate valve 20 serving as a holder is closed with a rather large pressing force for a firm fixing of the electrode 10, the pipe-shaped electrode 10 on the body 11 is formed. Local damage due to the pressing force of the gate valve 20 is easily generated, thereby causing a problem in that the sensitive electrode sensor installed inside the electrode 10 is also easily damaged, and the electrode 10 is connected to the gate valve 20. Once fixed, since the electrode 10 is always inserted into the fluid passage 25 in addition to the time for the administrator to directly measure the salinity, the salinity measurement by the electrode 10 is unnecessary for an excessive time. There was a problem, and the overall service life of the electrode 10 was reduced due to such damage and excessive measurement time of the electrode 10.

In addition, in order to repair or replace the electrode 10 due to various causes, it is necessary to open the gate valve 20 by rotating the handle 24 and then pull out the electrode 10. There was a problem that the fluid leaks from the fluid passage 25 to the outside through the gate valve 20, and the leaked fluid flows into various electric devices around the salinity measuring device, and not only the corrosion or damage of the peripheral device, There was also a problem that acts as a great risk to safety, in order to prevent this by installing a separate blocking device on the fluid passage 25 to block the flow of the fluid through the fluid passage 25 in advance and then the electrode rod 10 There was a problem that the repair and replacement of the electrode 10 is very cumbersome because it must be removed.

The present invention has been made to solve the above-mentioned conventional problems, the electrode holder for salinity measuring apparatus according to the present invention is installed by sliding the slider with the electrode in the casing is penetrated through the fluid passage to move the slider According to the present invention, the rear end of the electrode is inserted into and separated from the fluid passage and the casing is automatically sealed by the slider when the electrode is detached, thereby minimizing damage to the electrode generated during the use of the electrode, and measuring salinity by the electrode. It can be performed periodically only for the required time, thereby extending the service life of the electrode and, at the same time, completely blocking the leakage of fluid through the electrode holder when repairing or replacing the electrode. Improved efficiency and peripherals due to fluid leakage And that to prevent corrosion or damage from occurring to the technical problem.
