In general, a fitting is a fitting for connecting a pipe to a pipe in piping such as hydraulic construction, water supply, and boiler construction, or an air conditioner refrigerant pipe, and has a shape of a pipe having a passage for fluid flow therein.

For example, in heating boiler piping that connects pipes with flowing fluid such as hot water, when connecting pipes on both sides, they are mainly connected by fittings.

Also, in the refrigerant circulation circuit of the air conditioner, the refrigerant pipe can not be straightened but is extended and assembled at various angles and lengths along the design space. Such a refrigerant pipe is connected through a fitting as required.

In addition, a water treatment apparatus such as a water purifier, an ionizer, and a bidet for a toilet seat may be installed in a home, a company, or the like. A plurality of pipelines are connected to the water treatment apparatus to allow water to flow, Filters, corks, and the like.

These fittings are usually provided with threaded portions for fastening the threaded portions formed on the inner circumferential surface or the outer circumferential surface of the pipe end portion and have a nut-shaped tightening portion in the middle of the length so as to be fastened with a tool such as a spanner or the like.

For example, the fitting includes a fitting body in which a nut-shaped tightening portion is formed so as to protrude from a middle outer circumferential portion of a cylindrical hollow having an inner hollow and a male screw portion is formed on both opposite sides of the tightening portion, And a fitting connecting body having a female screw portion which can be fastened to the threaded portion of the fitting body.

The pressure output control unit 129 sends out a control signal to display the water flow status of the pipe to the outside.

The first piezoelectric layer 125a and the second piezoelectric layer 125b are provided in pairs in the piezoelectric element 125 such that the first and second piezoelectric layers 125a and 125b are thick Direction and the vibration is generated, a voltage is generated by the piezoelectric effect.

The metal shim 125c reinforces the rigidity of the first and second piezoelectric layers 125a and 125b.

As the piezoelectric layers 125a and 125b are bent, the electrical resistance characteristics are changed. That is, the piezoelectric layers 125a and 125b have resistances of specific values depending on the degree of bending depending on the difference in the flow velocity. Accordingly, the piezoelectric layers 125a and 125b change the value of the current flowing through the power source 125e and the sensing unit 125f, which form a closed loop depending on the degree of bending. Therefore, it is possible to detect the flow rate of the fluid.

The wire 125d connects between the piezoelectric layers 125a and 125b, the power source 125e, and the sensing unit 125f to form a closed loop. Accordingly, the current from the power supply 125e can flow through the wire 125d, and the sensing unit 125f can recognize a change in the current value and measure the flow rate.

The power source 125e constitutes a closed loop together with the piezoelectric layers 125a and 125b and the sensing part 125f. The power source 125e applies a constant voltage to the piezoelectric layers 125a and 125b so that current flows in the closed loop. Further, when the resistance values of the piezoelectric layers 125a and 125b are changed by a flow rate compared to a constant voltage applied from the power source 125e, the current value of the closed loop is changed. Accordingly, have.

The sensing unit 125f may measure the flow rate through a current value flowing in a closed loop formed together with the piezoelectric layers 125a and 125b and the power source 125e. The sensing unit 125f may be designed to have a resistance that is much smaller than the piezoelectric layers 125a and 125b so that the total current can be obtained through the measured voltage value without affecting the entire circuit have.

The function and effect of the pressure sensing means 120 of the present invention will be described below.

When the cooling water is introduced, the helical blade 124a of the inner housing 124 rotates. Since the wings are formed to be inclined, the wings are naturally rotated according to the inflow of water.

At this time, since the wing is installed in the inner housing 124, the inner housing 124 rotates, and the inner housing 124 rotates naturally according to the support of the ball bearing structure 122.

The ball bearing structure 122 is composed of an outer ring structure 122a, a ball bearing 122b and an inner ring structure 122c. The outer ring structure is fixed to the outer housing, and the inner ring structure 122 And naturally rotates according to the rolling action of the ball bearing 122b.

A piezoelectric element 125 is provided on the central axis 126 so that the spiral wing 124a of the piezoelectric element 125 is struck.

Then, the flow velocity of the water can be inferred by the electric circuit that forms the closed loop due to the generation of electric power of the piezoelectric element 125 provided on the central axis 126. [

That is, if the flow of the cooling water is fast, the rotational speed of the helical blade 124a is increased, and the impact to be blown to the piezoelectric element 125 increases, so that the amount of electricity generated in the piezoelectric element 125 increases. When the flow of the cooling water is delayed, The rotational speed of the wing 124a is slowed and the impact applied to the piezoelectric element 125 is reduced so that the amount of electricity generated in the piezoelectric element 125 is reduced.

In the sensing unit 125f, the electric quantity of the piezoelectric element 125 can be grasped and the flow of the cooling water can be grasped in real time, so that the cooling rate of the mold can be appropriately controlled.

That is, if the boiler fails and the flow rate of the water passing through the pipe does not change, it can be grasped through the piezoelectric element, so that the user can immediately take action through the warning means.

In addition, the present invention measures the temperature of water and outputs it to the outside in the form of a color. When the temperature of the water is high, it is displayed in red. When the temperature is low, it is displayed in blue.

And a temperature information output control unit 111 for providing a measurement sensor 110 for measuring the temperature of water and analyzing the result of the measurement sensor to select a color according to the temperature of the water, And a display unit 112 for displaying the color outside according to the output of the control unit and simultaneously outputting the information of the pressure sensing unit to the outside.

As described above, the present invention is not limited to the above-described embodiment, but is merely one embodiment for carrying out the connecting member for connecting the corrugated pipe with the connecting ring of the milling and the corrugated pipe. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. .
