The utility model is composed of a signal cylinder, an automatic adjusting valve and a by-pass line provided with an electric valve, wherein, the by-pass line and a liquid conveying pipe are connected in parallel, a contracting nozzle and an expanding throat which are matched are arranged in the automatic adjusting valve, an adjusting hole insertion device is installed on the contracting nozzle or the expanding throat, an inlet of an adjusting air pipe arranged in the middle of the automatic adjusting valve is connected with a volatile eduction pipe inserted in the signal cylinder, an air guiding window is arranged on the lower side of the volatile eduction pipe, and the liquid level of the signal cylinder reflects the requirements of liquid conveying. The automatic adjusting valve of a main body of the device does not have mechanical motion components and electric control elements in the normal operation of components, and the utility model has the advantages of scientific and reasonable structure, simplicity, compactness, high sensitivity in use, stable operation and wide adjusting range.
Description
(1) technical field:
The utility model relates to a kind of fluid level control device that influences gas or liquid flow.
(2) background technology:
In known prior art, what the device that liquid level is regulated and controlled adopted usually is the liquid trap that mechanical moving element is arranged, or the Automatic Control Component of electricity, magnetic contact arranged, the shortcoming of these fluid level control devices is complicated in mechanical structure, act frequently, easy to wear, perishable, malfunctioning phenomenon can take place after using a period of time and produce fault, making needs the liquid level of control out of control.Utilize the liquid level control device of hydrodynamic characteristic design though complicated machinery parts and electromagnetic contact self controlled element not needing to have occurred at present, the patent No. 00226091.3 " automatic control of liquid device " but find in particular cases that at the scene usable range is subjected to certain limitation during actual motion for example at some.
(3) summary of the invention:
The technical solution of the utility model is to adopt one not have automatic regulating valve, signal tube and the bypass line motorized valve of moving component to form the automatic control of liquid device.Automatic regulating valve is by the expansion trunnion of importing and exporting contracting noz(zle) of direction assembled in sequence and being complementary therewith in the housing of a triplet type, the flow area of contracting noz(zle) outlet and expansion trunnion inlet is suitable substantially, expansion trunnion inlet is bigger, the intermediate openings of triplet type automatic regulating valve is for regulating the inlet of tracheae, it is connected with the gas phase delivery line of signal tube, the gas phase delivery line inserts in the signal tube from the top, and its underpart has vertical air guide window.Upside at signal tube is installed the gas phase inlet tube, at the downside of signal tube the liquid phase inlet tube is installed.An expenditure and pressure device is installed in the lyophoby pipe before the inlet of automatic regulating valve, and it can adopt reduction valve or throttling orifice plate.Adjustment hole is installed on expansion trunnion or contracting noz(zle) is inserted device, its position of lifting can change effective flow area of contracting noz(zle) outlet or expansion trunnion inlet, makes this automatic control of liquid device can adapt to the variation significantly of ruuning situation better.The gas phase inlet of signal tube is connected to needs the side wall upper part of control liquid level equipment to allow under the highest liquid level at it, and the liquid phase of signal tube inlet is connected to the downside that needs control liquid level equipment, and the import of automatic regulating valve is connected to the bottom that needs control liquid level equipment by the lyophoby pipe.Liquid level in the signal tube is reflecting the liquid level that needs in the lyophoby equipment, liquid level in equipment descends, liquid level in the signal tube also and then descends, at this moment the circulation area of air guide window enlarges, the tolerance that permission is passed through increases, the tolerance that enters automatic regulating valve from the adjusting tracheae also increases, and at this moment will influence from contracting noz(zle) to flow into the amount of liquid minimizing of expanding trunnion, needs to control liquid level rise in the liquid level equipment thereby make; Otherwise when liquid level raises, the constriction in flow area of air guide window, the tolerance that permission is passed through also reduces, then also reduce from regulating the tolerance that tracheae enters automatic regulating valve, the amount of liquid that flows into the expansion trunnion from contracting noz(zle) increases, thereby the liquid level that needs in the control liquid level equipment is descended, so just realized automatic control of liquid need control liquid level equipment.
Some in particular cases for more effective control liquid level at a required optimum range, when liquid level reaches higher limit, the signal that the liquid level indication provides, be connected on the bypass line motorized valve by the liquid level signal converter, open bypass line, make the liquid level of system be adjusted to required optimum range rapidly, the liquid level signal converter is the liquid level indication of connected system directly, also can connect the liquid level indication of signal tube.
The advantage of this automatic control of liquid device is: scientific and reasonable for structure, simple compact, whole apparatus main body does not have mechanical moving component and electric controling element, safe and reliable to operation, not fragile, long service life, need not frequently adjust because of ruuning situation changes after once regulating, because effective actual internal area of automatic regulating valve can be adjusted, therefore can adapt to the ruuning situation load and change significantly, in very wide range of control, stably control liquid level, the bypass line of simultaneously reliable liquid level control, therefore highly sensitive, range of adjustment is wider.
