が生じる。In the above structure, the velocity of the primary liquid in the pipe is V
If it flows out from the orifice portion at a higher speed v, the pressure corresponding to (1/2 g) × (v 2 −V 2 ) between the orifice portion and the upstream side portion in the pipe. There is a difference. Therefore, when the primary liquid is supplied into the pipe in a state where the secondary liquid is contained in the upper space of the container, the following differences occur depending on the state of the control means.

なく、一次液のみが下流側へ供給される。In the first construction described above, when the control means is closed, the interior of the container communicates only with one of the orifice portion and the upstream side portion of the pipe, and the upper portion communicating with the orifice portion. Since there is no pressure difference between the secondary liquid stored in the space and the primary liquid stored in the lower space communicating with the upstream side, the secondary liquid is directed from the communication small hole toward the orifice. Only the primary liquid is supplied to the downstream side without flowing out.

次液との混液が下流側へ供給される。On the other hand, when the control means is opened, the inside of the container communicates with both the orifice portion and the upstream side of the pipe, and is accommodated in the upper space communicating with the orifice portion. In the state where the movable wall is displaced between the secondary liquid and, for example, the primary liquid contained in the lower space communicating with the more upstream side portion, the above (1 /
Resulting pressure difference corresponding to 2g) × (v 2 -V 2 ). For this reason, the primary liquid in the pipe is sent into the lower space in the container through the balance pipe, and the secondary liquid stored in the upper space flows out from the communication small hole toward the orifice part and passes through the orifice part. A mixed liquid of the primary liquid and the secondary liquid mixed in the liquid is supplied to the downstream side.

By changing the pressure of the primary liquid in the pipe which acts on the secondary liquid contained in the upper space of the container, the pressure difference between the primary liquid and the secondary liquid is changed from 0 to (1/2 g) × (v 2- V 2 )
Since the amount of the secondary liquid flowing out from the communication small hole toward the orifice portion of the pipe can be changed, the mixing ratio of the secondary liquid to the primary liquid can be changed.

The mixing ratio of the secondary liquid to the primary liquid can be changed by utilizing the pressure difference corresponding to (1/2 g) × (v 2 −V 2 ) between the liquid and the liquid.

側へ供給することができる。As described above, according to the present invention, a container for connecting the secondary liquid to the primary liquid is provided by connecting to the pipe to which the primary liquid is supplied, and the inside of the container is separated by the movable wall. The upper space in the container is connected to the orifice of the pipe through the communication small hole, the lower space in the container is connected to the upstream side of the pipe through the balance pipe, and the secondary liquid is stored in the upper space. It was configured to do. Thereby, when the primary liquid is supplied into the pipe at a speed V and passed through the orifice portion at a higher speed v, when the control means is open, the primary liquid in the pipe is displaced when the movable wall is displaced. Between the secondary liquid in the upper space of the container communicating with the orifice part (1/2
g) A pressure difference corresponding to (v 2 −V 2 ) occurs, the primary liquid in the pipe is sent from the balance pipe to the lower space in the container, and the secondary liquid stored in the upper space in the container communicates. It is mixed with the primary liquid passing through the orifice through the small holes. At this time, the pressure difference between the primary liquid and the secondary liquid can be adjusted from 0 to (1/2 g) × (v 2 −V 2 ) by adjusting the throttle of the control means. It is possible to freely change the mixing ratio of the secondary liquid with respect to. Further, when the control means is closed, the inside of the container communicates with only one of the orifice portion and the upstream side of the pipe, and communicates with the primary liquid in the pipe and the orifice portion. Since there is no pressure difference with the secondary liquid in the upper space of the container, only the primary liquid can be supplied to the downstream side without mixing the secondary liquid in the orifice portion.

ことができる。As a result of these, not only can the mixing ratio be changed without using up the chemicals being used, but also by using water as the primary liquid, the inside of the pump located downstream and the nozzles can be regularly cleaned. At this time, it is not necessary to mix the secondary liquid with the primary liquid in advance, so a small container may be used, and if the balance tube is connected to the container lid, the container body can be easily attached and detached so that the secondary liquid is replenished. Can be done easily.

The mixing ratio of the next liquid can be changed from 0 to various ratios.
