Two outlets connected respectively with the inlet communication of gas control flow valve 4 and oil return pipe 2, the gas outlet of electric Proportion valve 5 and gas control
The air inlet connection of flow valve 4, electric Proportion valve can control the rate of discharge size of gas control flow valve 4, automatic spray gun 6 have into
Hydraulic fluid port and oil outlet, the outlet of gas control flow valve 4 are connected by oil pipe 7 with the oil inlet 61 of automatic spray gun 6, automatic spray gun 6
Oil outlet 62 is plugged.
Above-mentioned existing adjusting automatic spray gun flow apparatus, since the oil outlet of automatic spray gun is usually plugged, the device
It can only realize from fuel feed pump 1 to triple valve 3 again to the cycling of oil return pipe 2, triple valve 3 to gas control flow valve 4 can not be arrived again certainly
This section of oil pipe of dynamic spray gun 6 realizes circulating for paint, the whole pipeline for not forming unimpeded Xun Huan, in the use of spray gun
In the process or it is of short duration it is deactivated after, due to containing metallic particles (such as aluminium paint) in paint, paint is easily in pipeline or automatic
Particle precipitation occurs in spray gun to be caused to block, and then influences flowing and spray that follow-up automatic spray gun carries out paint during spraying operation
The normal use of rifle.In addition existing electric Proportion valve is usually non-power-off maintenance, i.e., after a loss of power, existing electrical ratio
Valve can be stopped and close valve immediately causes the output of gas outlet non-compressed air, and then cannot open gas control flow valve and cause
Paint cannot flow through gas control flow valve.
Based on the above problem, thus this case generates.
Utility model content
It can form paint cycle pipeline the purpose of this utility model is to provide a kind of, avoid the adjusting blocked automatic
Gun traffic and anti-blocking rifle reflux.
In order to solve the above technical problems, the utility model provides following technical scheme：
Adjust automatic spray gun flow and anti-blocking rifle reflux, including fuel feed pump, gas control flow valve, electric Proportion valve, from
Dynamic spray gun and oil return pipe, the inlet communication of fuel feed pump and gas control flow valve, gas outlet and the gas control flow valve of electric Proportion valve
Air inlet connects, and electric Proportion valve adjusts the size of gas control flow valve flow by the air pressure that it is exported, and automatic spray gun has
Oil inlet and oil outlet, the outlet of gas control flow valve are connected by petroleum pipeline with the oil inlet of automatic spray gun, and automatic spray gun goes out
Hydraulic fluid port is connected with oil return pipe.
Further, the electric Proportion valve is power-off maintenance proportioning valve.
When the utility model paints oil inlet, flow into from fuel feed pump, by gas control flow valve, flowed into from automatic spray gun oil inlet
In automatic spray gun, when painting oil return, oil return pipe is flowed out to from the oil outlet of automatic spray gun.Therefore, paint flows form one and follow
Endless tube road, the oil outlet of such automatic spray gun due to entirety and form pipeline that is unimpeded, cycling, Bu Huizao there is no need to block
It is blocked in into paint in pipeline or automatic spray gun, and then ensures the proper flow of paint and the normal use of automatic spray gun.Gas
The high-precision flow valve of flow valve generally use is controlled, is painted after gas control flow valve, it, can be under the adjusting of electric Proportion valve
It realizes the fine adjustment to gas control flow valve oil outlet flow of paint, and then adjusts paint spray volume and the reflux of automatic spray gun
Amount improves the flexibility of automatic spray gun spraying operation and sprays the precision of real time control of oil mass.
Description of the drawings
Fig. 1 is the schematic diagram that the prior art adjusts automatic spray gun flow apparatus；
Fig. 2 is the schematic diagram that the utility model adjusts automatic spray gun flow and anti-blocking rifle reflux.
Specific embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.
In the description of the technical program, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instructions such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown is for only for ease of description the utility model and simplifies description rather than instruction or imply signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that this practicality
The limitation of novel protected scope, the utility model is described in further detail below in conjunction with the accompanying drawings.
Adjust automatic spray gun flow and anti-blocking rifle reflux, as shown in Fig. 2, including fuel feed pump 11, gas control flow valve 12,
Electric Proportion valve 13, automatic spray gun 14 and oil return pipe 18, the inlet communication of fuel feed pump 11 and gas control flow valve 12, gas control flow valve
12 import is used for oil inlet, and the gas outlet of electric Proportion valve 13 is connected with 12 air inlet of gas control flow valve, and electric Proportion valve 13 is logical
The air pressure of its output is crossed to adjust the size of 12 oil outlet flow of gas control flow valve, automatic spray gun 14 has oil inlet 141 and goes out
