Abstract
The utility model discloses an infrared inducting liquid level controlling device applied to the analytical instruments such as an atomic fluorescence, etc. to perform a liquid level control device, and belongs to the control instrument field. An infrared emission pole and an infrared receiving pole in pair for controlling the liquid level height are arranged at the position of the liquid level height required to be controlled on the main body of a circular air water separator. A waste discharge opening is arranged at the lower part of the air water separator, an electromagnetic valve is connected with the waste discharge opening through a conversing head, and the outlet opening of the electromagnetic valve is connected with a waste liquid bottle. The utility model inducts the liquid level through an infrared emission and receiving device, controls the liquid level through the electromagnetic valve, and can be operated under the situations of the ordinary pressure water discharging under ordinary pressure or the ordinary pressure water discharging under high pressure.
Description
Technical field
The utility model belongs to the control instrument scope, relates to a kind of infrared induction fluid level control device that carries out fluid level control device on the analysis instruments such as being applied in atomic fluorescence.
Background technology
The gravity flow control mode of the law of connected vessels that the liquid level control on the analytical instrument is now generally adopted.Adopt the device of similar linker, utilize the liquid level official post solution of both sides solution under atmospheric pressure state to flow out automatically and reach liquid level control purpose.But this device is owing to capillary reason has certain requirement to discharge area, when one side solution during not at atmospheric pressure state as just be difficult to reach the effect of control liquid level at high pressure conditions.
Summary of the invention
Can control liquid level in the process of discharging in order to make the solution that is under the pressure state to atmospheric pressure state, the utility model provides a kind of infrared induction fluid level control device, it is characterized in that: the infrared emission utmost point 5 that the control liquid level is installed on circular moisture trap main body 2, infrared receiving pole 6, put O type ring 7 on the infrared emission utmost point 5 and the infrared receiving pole 6, put into mounting cap 4, circuit lead passes from hollow screw 3, screw hollow screw 3, in the bottom of moisture trap main body 2 waste discharge mouth 1 is housed, solenoid valve 8 is connected with waste discharge mouth 1 by conversion head 9, and the outlet of solenoid valve 8 is connected to waste liquid bottle.
The liquid level position of the described infrared emission utmost point 5 and the infrared receiving pole 6 mounted in pairs needs control on moisture trap main body 2.
Described solenoid valve 8 is fixed on the pedestal by snubber assembly.
The beneficial effects of the utility model are by the fired infrared receiver induction level, and liquid level is controlled in the solenoid valve draining, can be at normal pressure to the normal pressure draining, and high pressure uses down the state of normal pressure draining.

D1 represents the infrared emission utmost point 5 among the figure; D2. represent infrared receiving pole 6, the D5 representative. solenoid valve 8.
Fig. 2, be the utility model apparatus structure synoptic diagram.
Embodiment
The utility model provides a kind of infrared induction fluid level control device.In the utility model apparatus structure synoptic diagram shown in Figure 2, the infrared emission utmost point 5 of control liquid level is installed on the circular moisture trap main body 2, infrared receiving pole 6, put O type ring 7 on the infrared emission utmost point 5 and the infrared receiving pole 6, put into mounting cap 4, circuit lead passes from hollow screw 3, screws hollow screw 3, and the infrared emission utmost point 5 and infrared receiving pole 6 are fixed on the liquid level position that the needs on the moisture trap main body 2 are controlled in pairs.In the bottom of moisture trap main body 2 waste discharge mouth 1 is housed, solenoid valve 8 is connected with waste discharge mouth 1 by conversion head 9, and the outlet of solenoid valve 8 is connected to waste liquid bottle.Described solenoid valve 8 is fixed on the pedestal by snubber assembly.
Below in conjunction with accompanying drawing the utility model is further specified.The utility model is to adopt the infrared induction liquid level, the principle of solenoid valve draining control liquid level.Fig. 1 is control circuit figure of the present utility model, and D1 represents the infrared emission utmost point 5 among the figure, and D2 represents infrared receiving pole 6, and when the liquid level on the circular moisture trap main body 2 among Fig. 2 was lower than desired location, on behalf of the solenoid valve D5 of solenoid valve 8, conducting between D1, the D2 close; When liquid level arrives desired location, disconnect between D1, the D2, represent the D5 of solenoid valve 8 to open, be in hull-borne, reach the effect of liquid level control thus.
