Abstract
The utility model discloses a micro flow quantitative controlling system used in chemical industry, machinery industry, and a spraying system. The utility model not only comprises a needle valve, but also comprises a solenoid valve controlled through a pulse controller, and a liquid pulse buffer for loosen-shaped filling material arranged between an inlet opening and an outlet opening, wherein the outlet opening of the needle valve is communicated with the inlet opening of the solenoid valve, the outlet opening of the solenoid valve is communicated with the inlet opening of the liquid pulse buffer, and the inlet opening of the pulse buffer is also communicated with an air pipe into which compressed air is conducted. The liquid flow can be controlled to a few drops per minute even smaller through the micro flow quantitative controlling system of the utility model, and the flow of a flowing fluid is steadier.
Description
(1) technical field:
The utility model relates to a kind of flow control system, is a kind of micro-flow quantitative control system specifically.
(2) background technology:
The traditional industry element of control fluid flow is a valve, valve element commonly used in the time will controlling tiny flow quantity is a needle-valve, is several even more hour but want controlling liquid per minute flow, utilize valve that liquid is carried out accurate trickle control, for example: in chemical industry, the interpolation of micro liquid; Site-directed quantitative in the machinery industry is lubricated; When in the spraying system droplet control being reached micron, submicron order, needle-valve equally also can " malfunctioning ".And per minute flows out several liquid control, the latus rectum that requires needle-valve in theory is several silks, although liquid can apply certain pressure, but when it passes through several through hole, because capillary effect, cause the pressure that had originally will decay near zero, if run into small and weak buffer brake on the road in the place ahead or tiny dust is in the way, liquid will halt.Generally speaking, in a lot of use occasions, the control of tiny flow quantity is very unstable, and the probability that faults such as obstruction, cutout occur is higher.
(3) utility model content:
At the control defective of above-mentioned needle valve element, the purpose of this utility model has provided a kind of micro-flow quantitative control system of effective control tiny flow quantity.
Can remedy the micro-flow quantitative control system of above-mentioned defective, the key of dealing with problems be make liquid in pipeline not through the control element of too thin latus rectum, avoid the pressure loss in the liquid transfer process, this design comprises that the liquid pulse flow produces system and fluid flow buffer system, and the liquid pulse flow produces system and is communicated with buffer system.After the band pressure fluid comes out from liquid storage equipment, enter the liquid pulse flow and produce system, enter the fluid cushion system again, just formed steady, tiny fluid after coming out.
Liquid pulse flow generation system includes needle-valve, solenoid valve, and buffer system is the liquid pulse impact damper, and the mode that the three connects into a system is the import of the outlet connection solenoid valve of needle-valve, and the outlet of solenoid valve is communicated with the import of liquid pulse impact damper.
Solenoid valve is connected with impulse controller by circuit, and the switching time (pulsewidth) and the frequency of solenoid valve are controlled by impulse controller.
The import of liquid pulse impact damper also is communicated with the tracheae that pressurized air is imported, and tracheae is introduced pressurized air in the liquid pulse impact damper, carries away overflowing to liquid pulse device outlet liquid on every side.
Described liquid pulse impact damper comprises snubber assembly, and snubber assembly is the loose shape filler of being located between import of liquid pulse impact damper and the outlet, and the simplest filler is filamentary material or is poroid material.
Described import and outlet preferably lay respectively at the top and the bottom of liquid pulse impact damper.
Described tracheae pipeline is provided with reduction valve, so that regulate the gaseous tension that enters in the liquid pulse impact damper.
The utility model micro-flow quantitative control system also is provided with the fluid flow detection system, and the fluid flow detection system is a flowmeter, and the outlet of flowmeter is communicated with the import of needle-valve.
In the said structure, the given flow radix of needle-valve, its flow of process can be several times or tens times of last use traffic, during fluid process solenoid valve, switching time ratio in the solenoid valve unit interval is controlled by impulse controller, the shut-in time of general solenoid valve is longer than several times to tens times of open-intervals, the latus rectum of needle-valve has just increased several times and even tens times like this, increased the transmission of fluid pressure, build-up of pressure loss when having avoided the narrow and small hole of liquid by several and phenomenon of blocking.The frequency that solenoid valve opens and closes can be regulated according to the needs of the steady degree of fluid.The flow of described needle-valve is by the pulse-width regulated control of impulse controller, after the shape pulse liquid at intermittence that solenoid valve comes out enters the liquid pulse impact damper, under the effect of gravity and surface tension of liquid, liquid flows into filler, fill up the space of filler, be slow overflow situation, be compressed gas in the exit of liquid pulse impact damper by pressure gas and the formed fluid-mixing of liquid at last and release, form fluid-mixing stably.
Advantage of the present utility model:
1, the utility model micro-flow quantitative control system can control to several of per minutes even littler to fluid flow, and the flow of effluent fluid is comparatively steady.
2, the liquid pulse impact damper of the filled formula of air pressure of the utility model micro-flow quantitative control system original creation, cost of manufacture is low, and operation is simple and reliable for this control method, and operating cost is low.
3, the utility model micro-flow quantitative control system is applicable to and allows the occasion that gas exists.
