Improved pressure chemical sprayer

Improved pressure chemical sprayers, through its safety valve spool and unloading hole set cone, so that moves freely, reliable and ensure a smooth and timely case overpressure unloading. In the chemical pressure generator B cup to set long-mouth funnel can be quantitatively, so that the drug barrel of liquid spray finished and continues to produce high-pressure gas may cause danger to get released. In the direct effects of the drug by the high-pressure gas on the top plane of the lid providing the reinforcing ribs to increase their strength and rigidity, to prevent rupture, the pressure above points upon the chemical spray to use more secure.
Improved pressure chemical sprayer, drug tub 1 with the lance 2, the pressure tube 3, a suction pipe 5, chemical pressure generator 7, the safety valve 6, the medicine bucket 1 is a binocular type, the internal passageway, outside tendons and board connected to the boom 2, pressure pipe 3, straws four drugs have been linked into the barrel, chemical safety valve pressure generator 7 and 6 were installed in two top tube, chemical pressure generator 14 and is located by the a Cup a cup of abdominal its bottom a drop hole 27 b cup and b cup into the lever among components, a cup hanging in medicine bucket cylinder port, b cup bucket cylinder coupled to the mouth of the big drug flap 18 , lever assembly through b cup big mouth cover 18 fixed to the central projection, the adjusting lever assembly, the pin 19 and the lower rod 20 connected via screw connection into one, on the next step with the big rod between the flaps springs.
