CONSTITUTION:A water supply passage 9 is connected to a dilution chamber 8 mixing raw solutions A, B with tap water so as to supply tap water to said chamber 8 by the pressure thereof and a diluted solution taking-out passage 10 is connected to the dilution chamber 8 so as to take out the diluted solution by the water supply pressure of the dilution chamber 8. Liquid supply valves V1, V2 and a water supply valve V3 are opened and closed by a dilution control means 43. A mode altering means 44 is provided so that the liquid valves V1, V2 are opened when set taking-out quantity is little and the water supply valve V3 is opened after a set delay time when said taking-out quantity is much. By this constitution, a desired amount of a diluted solution is accurately taken out and the raw solutions are prevented from the mixing with the next taken-out diluted solution.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diluter for diluting a stock solution with tap water.

[0002]

2. Description of the Related Art In this type of diluter, tap water is conventionally supplied by tap water pressure to a diluting chamber for mixing an undiluted solution and tap water, and the diluting liquid is taken out from the diluting chamber by the water pressure of the diluting chamber. There were some that could easily supply and remove water using the water pressure.

[0003]

Conventionally, it is judged whether the amount of the diluted liquid taken out from the diluting device has accumulated in the receiving container or not, and it is judged whether or not the desired amount is taken out. Since the withdrawal amount of the diluting liquid is adjusted by an artificial operation, it is easy to cause an excess or deficiency in the withdrawal amount, and it is necessary to monitor the accumulated amount so that a desired amount can be withdrawn. The object of the present invention is to use tap water pressure for water supply and withdrawal, but it is possible to take out a desired amount of diluting liquid with high accuracy both in terms of volume and quality, and as quickly and easily as possible. To provide a diluter.

[0004]

In order to achieve the object, the diluting device according to the present invention is provided with a diluting chamber for preparing a diluting liquid by mixing the stock solution with tap water, and the diluting chamber is provided with a tap water. A constant flow rate for connecting tap water for supplying tap water by water pressure and a take-out path for taking out the diluting liquid from the diluting chamber by the water supply pressure of the diluting chamber to the diluting chamber and for maintaining a constant tap water flow rate for the diluting chamber. A control valve is provided in the water supply passage, and a liquid supply valve that opens and closes the liquid supply passage that allows the undiluted solution to flow into the dilution chamber and a water supply valve that opens and closes the water supply passage are provided, and the amount taken out by the extraction passage is set. In addition, a setting device for changing and adjusting is provided, and the liquid supply valve and the water supply valve are automatically opened / closed based on the information from the setting device, and the amount taken out by the take-out path is set and taken out by the setter. Controlled by quantity The dilution control means is linked to the liquid feed valve and the water feed valve, and when the set take-out amount by the setter is small, the water feed valve is turned on after the set delay time elapses after the liquid feed valve is opened. When the control mode by the dilution control means is automatically switched to the time difference mode in which the valve is controlled to open, and when the set take-out amount by the setter is large, the liquid supply valve and the water supply valve are simultaneously opened. The dilution control means is additionally provided with a mode changing means for automatically switching the control mode by the dilution control means to the simultaneous mode in which the valve is controlled to operate. The action and effect are as follows.

[0005]

The desired take-out amount is set as the set take-out amount by operating the setting device. Then, the dilution control means automatically opens and closes the liquid supply valve and the water supply valve based on the information from the setter and the mode changing means, and the constant flow control valve of the constant flow control valve is operated by the tap water pressure and regardless of the change of the water pressure. Therefore, the running water becomes constant and the tap water flows into the diluting chamber, and the undiluted solution flows into the diluting chamber at the inflow amount determined by the opening degree of the liquid supply valve and the control, and the diluting liquid is created. The liquid is sent out of the diluting chamber to the take-out path by its water supply pressure. When the set amount of diluent is delivered, the dilution control means automatically controls the valve to automatically stop the water supply and stop the delivery of the diluent. If the tap water flow rate for supplying water to the dilution chamber is constant, the smaller the set amount of diluting liquid taken out, the smaller the amount of water that needs to be supplied. Therefore, all the required supply water passes through the dilution chamber. It takes less time. Further, the amount of undiluted solution that needs to be supplied to the diluting chamber is smaller than the amount of water, and the undiluted solution has a higher viscosity than water and is difficult to flow. Due to these things, when the withdrawal amount is small, if the dilution control means controls the liquid supply valve and the water supply valve to open at the same time, a part of the undiluted solution will flow after all the required supply water has passed through the dilution chamber. The stock solution flows into the diluting chamber and tends to remain in the diluting chamber or the take-out path. In the device according to the present invention, by appropriately setting the set delay time, the dilution control means automatically switches to the time difference mode due to the mode changing means even when the take-out amount is small, and the stock solution is diluted. The diluting liquid can be taken out while the feed water has passed through the diluting chamber after the inflow into the chamber and the feed water has flowed out all of the stock solution. In addition, when the amount to be taken out is large, the dilution control means is automatically switched to the simultaneous mode, the required amount of supplied water is large, and it takes a relatively long time for all the required amount of supplied water to pass through the dilution chamber. For that reason, and because of this, and for the end of the inflow of the stock solution into the diluting chamber and then the passage of the feed water through the diluting chamber, while making the supply water flow out all of the undiluted solution, Diluent can be withdrawn while allowing the total volume to flow out faster than controlled in stagger mode.

[0006]

EFFECTS OF THE INVENTION By utilizing tap water pressure for supplying water or taking out a diluting liquid, it is possible to easily use the water supply channel by connecting it to the water supply and to use it inexpensively without using a pump. Equipped with a constant flow rate control valve, mode change means and dilution control means, you can easily and accurately take out the desired amount of diluting liquid by operating the setting device, and the undiluted liquid remains in the diluting chamber etc. regardless of the amount taken out. Then, it could be taken out as quickly as possible without being mixed in the next taken-out diluent, so that it could be used efficiently without waste.
