The valve body 413 which blocks a pipe | block and cuts off a pipeline is inserted. The valve body 413 may be used in the form of a float that floats well inside the water. The check valve 410 is the upper inlet 415 of the valve body 411 is connected to the lower outlet 433 of the atmospheric pressure inlet 430, the lower outlet 416 of the valve body 411 is a venturi tube ( 401 is connected to the top inlet 405.

The check valve 410 of the injector 11 is the water pumped by the pump (7) is injected into the venturi tube 401, when the vacuum pressure is formed at the bottom of the valve body 413 in the valve body 411 is The pipe is opened while being moved downward and separated from the valve seat portion 412, and thus the chlorine gas flowing into the inside continues to flow out and is discharged into the input pipe 22.

Then, when the pump 7 is stopped or an abnormality occurs in the equipment and the vacuum pressure drops, the water rises inside the valve body 411, causing the valve body 413 inside the valve body 411 to be leaked by water. As it floats, the valve seat portion 412 comes into close contact with the back of the water.

The hydraulic pressure discharge part 420 has a cover 422 is coupled to the body 421, the outlet 425 is formed on one side of the main wall, the diaphragm 423 is coupled to the inside, and the middle portion of the body 421 The communication port 428 formed in the coupling is coupled to the communication port 414 formed on one side of the main wall of the valve body 411, the body 421 is formed with a seat portion 426, the middle of the diaphragm 423 A spring 427 for adhering the valve plate 424 to the seat portion 426 is coupled between the valve plate 424 fixed to the portion and the intermediate portion of the cover 422.

The diaphragm 435 is fixed to the middle portion. A through hole 437 is formed in the middle portion of the valve plate 436 fixed to the middle portion of the diaphragm 435 so that the intermediate valve body 438 is inserted in a flowable manner and downwards by the spring 439. It is elastically supported, and the part which the valve plate 436 and the head 440 of the intermediate valve body 438 contact is formed with the arc surface 441,442 so that it may be in close contact stably. The upper valve body 443 for opening and closing the atmospheric pressure inlet 434 formed in the cover 432 is coupled to the upper portion of the intermediate valve body 438.

In the atmospheric pressure inlet 430, the diaphragm 435 and the valve plate 436 move downward by the vacuum pressure of the venturi tube 401, so that the arc surface of the valve plate 436 and the intermediate valve body 438 ( 441 and 442 are spaced apart so that chlorine gas flows inward and flows downward, and the intermediate valve body 438 as the spring 439 is compressed and exerts a force by moving the valve plate 436 downward. ) And the upper valve body 443 are pulled downward, and the upper valve body 443 blocks the atmospheric pressure inlet 434 of the cover 432, thereby preventing the inflow of external air.

When the chlorine gas is used up, when the machine is stopped, a vacuum is applied in the machine, and the water flows back into the machine pipe, so that the diaphragm 435 and the valve plate 436 are lifted up, and the intermediate valve body 438 As the upper valve body 443 rises upward, the atmospheric pressure inlet 434 is opened, so that the outside air is introduced and the vacuum is released to prevent the backflow of water.

The electric valve (4), pump (7), automatic control valve (12), flow rate sensor (13), gas alarm (15) and hydraulic alarm (18) are electrically controlled by the controller (30). Connected.

Referring to the operation of the injector of the present invention automatic chlorine injector configured as described above are as follows.

The controller according to the operating conditions such as the inflow rate of the purified water from the water purification plant to the inlet (8a) of the reservoir (8), the discharge rate to the outlet (8b), the concentration of chlorine gas to be mixed with water By operating the control panel 31 of (30) and inputting the necessary data to the microcomputer, the microcomputer controls the electric valve 4, the pump 7 and the automatic control valve 12 to automatically start the device and start the operation. The appropriate amount of water in the drainage basin 8 according to the flow rate of the heavy water, the flow rate detector 13, the concentration sensor 23, the gas alarm 15 and the hydraulic alarm 18, and the operator's operation signal. Chlorine gas is actively added and mixed.

When the power is applied to the apparatus and operated, the pump 7 pumps water to spray the venturi tube 401 of the injector 11 at a high speed, whereby a vacuum pressure is formed by the venturi tube 401, thereby liquefied chlorine communication ( The chlorine gas of 1-1) is discharged by the strong vacuum pressure and flows into the pipeline of the pipe L, and eventually is mixed in the water of the drainage basin 8 through the input pipe 22. Thus, chlorine gas is used for sterilization and the like. The mixed water is fed to the village.

Hereinafter, the process described in this order, when the chlorine gas of the liquefied chlorine cylinder (1-1) is discharged by the vacuum pressure of the injector 11 is filtered by the filter (3), the pressure reducing valve ( 5) the pressure is reduced to an appropriate pressure, and a proper amount set by the metering control valve 6 flows to pass through the tapered sensor tube 200 of the flow rate sensor 13.

At this time, the flow rate sensor 13 changes the height of the flow ball 210 flowing in the tapered sensor tube 200 according to the flow rate of the chlorine gas, the height of the flow ball 210 to the flow sensor 14 ) Is detected by the optical sensor 220 for position detection, and the flow rate detection signal is input to the microcomputer.

Subsequently, the automatic control valve 12 operates in accordance with the control signal of the microcomputer output in conjunction with the flow rate detection signal to adjust the flow path of the valve to automatically adjust the flow rate of chlorine gas, The chlorine gas passing through is supplied to the injector 11 through the pipes L7, L5, and L6 and discharged to the inlet pipe 22 through the venturi pipe 401.

When the chlorine gas is mixed with the water in the basin 8 as described above, if the gas alarm 15 detects the chlorine gas flow rate and is insufficient, an alarm sounds and the signal is transmitted to the microcomputer to operate the device. In addition, the water pressure alarm 18 detects the water pressure pumped by the pump 7 and if the water pressure is insufficient, an alarm also sounds and this signal is transmitted to the microcomputer to stop the operation of the device. After changing the communication (1-1), taking necessary measures such as repairing the pump (7), and resetting the controller (30) again, it operates normally.

On the other hand, if the device suddenly stops due to a power failure in the situation where the mixing action of chlorine gas proceeds normally, since the vacuum negative pressure is formed in the pipe L, the water pressure of the drainage basin 8 flows back into the pipe of the pipe L. In addition, if the pipe is installed higher than the injector 11 or several injectors 11 are installed in one line, water may flow back into the machine if the valve is not operated properly. However, at this time, even if the back flow of water is blocked by the check valve 410 of the injector 11 and the back flow is not blocked by the check valve 410, the water pressure is discharged through the water pressure discharge unit 420 so that the apparatus is discharged. Keep safe

When the chlorine gas is used while the vacuum is generated by the venturi tube 401 of the injector 11 and the chlorine gas is smoothly discharged, when the apparatus is stopped, a vacuum is applied to the pipe and water rises inside the machine. As the diaphragm 431 of the atmospheric pressure inlet 430 is reversed, air is injected to make the vacuum in the pipe weightless, thereby preventing water from rising.

As described above, the injector of the present invention automatic chlorine injector is provided with a check valve and a hydraulic pressure discharge part in the injector, and can prevent a power failure due to vacuum negative pressure even when the device is temporarily stopped due to a sudden power failure. Even if the pipe is installed higher than the injector or multiple injectors are installed in one line, even if the valve is not working properly, the equipment can be safely used by completely preventing the backflow of water into the machine.

In addition, when the chlorine gas is used while the vacuum is generated by the venturi tube of the injector and the chlorine gas is smoothly discharged, when the device is stopped, the atmospheric pressure inlet unit injects outside air to bring the vacuum in the pipe into zero gravity. This prevents water from flowing back.

Therefore, the present invention has the advantage of always mixing the appropriate amount of chlorine gas by measuring the concentration of chlorine gas mixed in the water of the drainage in real time, and when the machine is stopped while the chlorine gas of the liquid chlorine communication falls This prevents water from flowing back due to vacuum, and prevents water from flowing back when the piping equipment is stopped by power failure or stopped by failure of pump, etc., so that the equipment can be used safely and the service life can be extended. In addition to being able to, there is an advantage that contributes to the simplification and miniaturization of the equipment.
