Description

Apparatus for automatically liquid chemicals into a water supply pine by using a venturi tube}

The present invention relates to an apparatus for injecting a liquid medicine using venturi, and more particularly, a first chemical storage chamber for storing chlorine in a liquid state, a second chemical storage chamber, an input detector and an input control valve, a venturi tube, and a backflow prevention valve. Thus, the present invention relates to a liquid medicine injector using venturi, which can automatically administer liquid chlorine stored in a chlorine storage chamber by a pressure difference of water flowing in a venturi tube connected to a water supply pipe.

In general, even though the water supply is not serious, even if the water is continuously supplied through tap water or groundwater pumping, it contains a small amount of pollutants. In this case, in general, water purification chemicals containing chlorokalky or chlorine are introduced into a water storage tank temporarily storing a net in a water supply line, and the water is purified simply while staying in the water storage tank. In the conventional conventional method of simple water purification, solid water purification chemicals are soaked in a net bag or a mesh container and soaked in the reservoir tank so that the water supplied along the water line is melted from the net bag or container during the temporary stay in the reservoir tank. The method of purifying by the chemical reaction of water purification chemicals has been used.

However, such a conventional simple water purification method is not always constant in the ratio of purified water to water, when the concentration of purified water is high, due to the smell of the drug to produce water that is unsuitable for drinking water, the concentration of purified drug If it is low, there was a problem in mass production of water that is not properly purified.

The present invention was devised to solve the above-mentioned conventional problems, and an object of the present invention is to provide a first chemical storage chamber, a second chemical storage chamber, a dose detector and an input control valve, a venturi tube, and a backflow to store liquid chlorine. Providing a prevention valve, to provide a liquid chemical injection device using a venturi that can automatically administer the liquid chlorine stored in the chlorine storage chamber by the pressure difference of the water flowing inside the venturi tube connected to the water supply pipe.

In order to achieve the object of the present invention as described above, the present invention,

A venturi tube in the water supply pipe extending from the water source to the outside, a first drug reservoir for storing the drug, a connection extending between the first drug reservoir and the venturi tube and transferring chlorine from the first drug reservoir into the venturi tube. A check pipe is provided, and a check valve is arranged in the connection transport pipe at an adjacent position of the venturi pipe, and an input detector is arranged in the connection transport pipe at an adjacent position of the first chemical storage chamber, and a connection is established between the check valve and the charge detector. The pipe provides a liquid chemical injection device using a venturi in which a dose control valve is disposed.

As described above, according to the present invention, by providing a first chemical storage chamber, a second chemical storage chamber for storing chlorine in the liquid state, an input detector and an input control valve, a venturi tube and a backflow prevention valve, the venturi connected to the water supply pipe The liquid chlorine stored in the chlorine storage chamber can be automatically administered by the pressure difference of the water flowing in the tube.

Hereinafter, with reference to the accompanying drawings will be described a liquid chemical injection device using a venturi according to an embodiment of the present invention.

1 is a block diagram showing a liquid chemical injection device using a venturi according to the present invention, and Figure 2 is a view showing the input detector shown in FIG.

1 and 2, the liquid medicine injection device 100 using a venturi according to the present invention is a venturi tube 110, which is built in a water supply pipe (A) extending from the water source to the outside, to store the drug in the liquid state Connection transport pipe 130 extending between the first drug storage chamber 120 and the first drug storage chamber 120 and the venturi tube 110 and for transporting the drug from the first drug storage chamber 120 into the venturi tube 110 It is provided. Preferably, the drug is liquid chlorine.

The connection transport pipe 130 includes a first transport pipe 132 in communication with the first medicine storage chamber 120. An input amount detector 134 is disposed at an extension of the first transfer pipe 132. The dose detector 134 has a cochlear shape, is made transparent to see through the inside, and a scale is formed on the outer surface. The second feed pipe 136 extending from the dose detector 134 is disposed on one side of the dose detector 134 thus formed, and the dose control valve 138 is disposed on the extension of the second feed pipe 136. In addition, a third transfer pipe 140 extending from the dose control valve 138 is disposed on one side of the dose control valve 138, and the inside of the venturi tube 110 is extended to the extension of the third transfer pipe 140. A non-return valve 142 is disposed to prevent water from flowing to the first chemical storage chamber 120, and a fourth transfer pipe 144 connected to the venturi tube 110 is disposed at one side of the non-return valve 142. do.

In this case, the dose detector 134 is selectively coupled and separated between the first transfer pipe 132 and the second transfer pipe 136.
