Abstract
The invention discloses a paint flow control device. The paint flow control device comprises a paint supply pump and an automatic spray gun, wherein a discharge end of the paint supply pump is connected with an impeller conveyor; one end of the impeller conveyor is connected with the paint supply pump through a pneumatic butterfly valve; the other end of the impeller conveyor is connected with the automatic spray gun through a paint delivery pipe; a flow meter and a precision flow regulator are also arranged on the paint delivery pipe; the precision flow regulator comprises a trace cone valve and an electronic range finder which is arranged on a cone valve adjusting rod. According to the flow control device, high-precision paint flow control is achieved; the paint can be stably output at a micro flow; and meanwhile, linear control on the paint flow under the high-precision micro flow output can be achieved.
Description
Technical field
The present invention relates to application treatment facility field, be specially a kind of coating volume control device.
Background technology
In external coating treatment process; often can run into the situation of trace spraying; conventional settling mode is nothing more than two kinds; one is regulated by the opening degree of the flow control valve controlling spray gun in spraying process; two is on paint delivery tube line, install flow control valve (FCV) additional, is controlled the flow of pipeline inside courtyard by the diaphragm in FCV by air pressure.These two kinds of modes respectively have feature but all there is micrometeor and control inaccurate defect:
Although spray gun regulates simple, owing to being subject to the restriction of the flow control valve structural design of spray gun, Flow-rate adjustment cannot carrying out continuity adjustment, and can only carry out with the flow control mode of great-jump-forward; And the limited precision of control valve on spray gun, successional delicate flow can not be realized especially by this way and control, the sharply change of quantity for spray can be occurred on the contrary because of the instability of Artificial Control control valve, affect spraying effect.
The mode that pipeline installs additional FCV can realize comparatively meticulous flow-control to a certain extent, but because the adjustable range of the diaphragm in FCV is limited, easy generation lag output phenomenon, and trace export on precision not good, low during height when there will be flow in certain hour section, be difficult to tackle high-precision output and control.
Summary of the invention
Technical problem solved by the invention is to provide a kind of coating volume control device, to solve the problem proposed in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Coating volume control device, comprise paint supply pump, automatic spray gun, the discharge end of paint supply pump is connected with impeller conveyer, impeller conveyer one end is connected with paint supply pump by Pneumatic butterfly valve, the impeller conveyer other end is connected with automatic spray gun by paint delivery tube, described paint delivery tube is also provided with flowmeter and delicate flow adjuster, described delicate flow adjuster comprises micro-vertebra valve and is arranged on the electrotape on vertebra valve regulation bar.
Further, also comprise the paint return pipe be connected on delicate flow adjuster, described paint return pipe is also provided with back pressure controller.
Further, the quantity of described automatic spray gun is at least two.
beneficial effect
The present invention realizes high-precision coating flow-control, while the coating stably carrying out micrometeor exports, more can realize the coating flow alignment control under high precision micro output.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In order to make actualizing technology means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
As shown in Figure 1, coating volume control device, comprise paint supply pump 1, automatic spray gun 8, the discharge end of paint supply pump 1 is connected with impeller conveyer 2, impeller conveyer 2 one end is connected with paint supply pump 1 by Pneumatic butterfly valve 3, impeller conveyer 2 other end is connected with automatic spray gun 8 by paint delivery tube 5, described paint delivery tube 5 is also provided with flowmeter 4 and delicate flow adjuster, the electrotape 8 that described delicate flow adjuster comprises micro-vertebra valve 7 and is arranged on vertebra valve regulation bar.Also comprise the paint return pipe 9 be connected on delicate flow adjuster, described paint return pipe 9 is also provided with back pressure controller 10.The present invention realizes high-precision coating flow-control, while the coating stably carrying out micrometeor exports, more can realize the coating flow alignment control under high precision micro output.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
