Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a tube joint for measuring electric conductivity, in which an electrode for measuring electric conductivity is provided on a tube joint for liquid.

[0002]

[Prior art]

 Conventionally, the structure of a tube joint for measuring the electrical conductivity of a liquid has a metal joint electrode inside the tube joint and a lead wire for measurement. Since the component parts were divided into the functional part for performing the work, the work of assembling the component parts occurred, and it was necessary to take measures against water leakage between the component parts.

[0003]

[Problems to be solved by the device]

 SUMMARY OF THE INVENTION The present invention aims to provide a component which eliminates the above-mentioned drawbacks and which has a reduced number of components and which does not require measures against water leakage.

[0004]

[Means for Solving the Problems]

 Conductive plating 2 is applied to the inside and outside of both ends of the tube fitting on the insulating tube fitting 1 with flanges 3 on both ends, and the conductive plating 2 of the tube fitting 1 is sandwiched between the metal clips 4. Fix and measure the electrical conductivity of the fluid flowing from the metal clip 4 into the tube fitting 1.

[0005]

[Action]

 In the present invention, the tube joint 1 is subjected to the above-mentioned conductive plating treatment, so that it is possible to combine the constituent parts of the portion functioning as a tube joint and the functional portion for measuring electric conductivity into one part. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings of FIGS. 1, 2, 3, and 4. FIG. 1 is a perspective view of an insulative tube joint 1 having flanges 3 on both ends, and a conductive tube 2 having conductive plating treatment 2 applied inside and outside the both ends of the tube joint. The tube 6 is connected to the flange 3 to the tube joint as shown in FIG. 2, and the metal clip 4 is sandwiched so as to be pressed against the conductive plated portion 2. As shown in FIGS. 3 and 4, the metal clip 4 has a circular shape so as to come into pressure contact with the plated portion 2, and the lead wire 5 is fixed thereto.

Next, another embodiment of the present invention will be described with reference to the drawing of FIG. FIG. 5 is a cross-sectional view showing that when connecting the tube 6 to the tube joint 1, the tube 3 is connected so as to cover the flange 3 and is connected as a tube pull-out prevention flange.

[0008]

[Effect of device]

 The present invention does not require water leakage measures and is easy to create. It can also be easily attached and detached. The flange functions as a tube pull-out prevention flange when used as a tube joint, and as a tube stopper when measuring electrical conductivity.
