薬液を噴霧するものである。 15 is an air relief valve, as shown in Figure 2 of Japanese Patent Publication No. 54-37321, when compressed air pressure is applied to the upper chamber and the pressure of the chemical liquid is applied to the lower chamber, the piston moves to the balance position and the lower chamber is opened. It has a spillway that can be communicated or shut off, thereby sending a chemical solution with a hydraulic pressure balanced with the air pressure to the lance 4, and spraying the atomized chemical solution mixed with air from the nozzle 5 of the lance 4.

The conventional method described above is very effective as a method for maintaining a good fog condition by always adjusting changes in air pressure and hydraulic pressure due to changes in engine speed (PTOrpm changes) to a constant ratio.
しかし、反当り散布量を一定範囲で加減しよう
としたり、走行速度の微妙な変化にあわせて噴霧

かかるという問題がある。 However, if you try to adjust the amount of spray spray within a certain range or change the spray amount itself in response to subtle changes in the running speed, it is necessary to restrict the lift amount of the air relief valve 15, or to adjust the amount of spray applied to the piston diameter. There is a problem in that it takes time and effort to change each time.

In order to solve the above problems, this invention provides at least two pressure regulating valves in series in the middle of the liquid sending pipe that pressurizes the chemical liquid in the chemical liquid tank with a plunger pump etc. and sends it to the lance (multi-head jet pipe). The method is characterized in that the flow rate of the chemical liquid entering the lance from the liquid feeding pipe is adjusted by an orifice, and the liquid is mixed with compressed air and sprayed in a plurality of nozzles attached to the lance.

FIG. 1 shows an embodiment of the present invention, in which a secondary pressure regulating valve 16 and an orifice chamber 18 are provided in place of the conventional air relief valve. Other parts are second
Since it is the same as the conventional example shown in the figure, the same reference numerals are given and the explanation will be omitted.

Pressure is applied by the next pressure regulating valve 16, and the chemical liquid to which this pressure has been applied is sent into the lance 4 through the orifice 19 in the orifice chamber 18.
こうして送られた薬液はランス４内の薬液通路

As described above, this invention provides two or more pressure regulating valves in series in the liquid feeding pipe provided at the discharge port of a plunger pump for chemical liquids, so that the required pressure can be taken out from each valve, and the primary pressure of high pressure is It is used for stirring a chemical liquid tank, etc., and the relatively low secondary pressure is used for spraying, and the amount passing through the orifice is determined by the secondary pressure.
