Abstract
A liquid level and alarm control device for a vacuum liquid absorbing trolley comprises a solenoid valve, an electric horn and a liquid level detecting bar, wherein the liquid level detecting bar is connected with the solenoid valve and the electric horn by leads, the solenoid valve and the electric horn are connected in parallel and then are connected on the positive pole of a vacuum liquid absorbing trolley storage battery by leads, the liquid level detecting bar is arranged on a vacuum liquid absorbing trolley tank body, when liquid in a vacuum liquid absorbing trolley tank touches the detecting bar, a line is conducted, the solenoid valve is switched on, the pressure in or outside the vacuum liquid absorbing trolley tank body can be balanced, therefore, the liquid absorption inward the vacuum liquid absorbing trolley tank is stopped, and simultaneously the electric horn gives an alarm. The liquid level and alarm control device for the vacuum liquid absorbing trolley has the advantages of being high in liquid level control precision and reliable in performance.
Description
Technical field:
The utility model belongs to special car and makes the field, relates in particular to a kind of vacuum liquid-absorbing automobile liquid level and alarm control unit.
Background technology:
The various brand liquid-absorbing automobile control liquid levels of using in the market generally adopt the float ball valve, utilize the buoyancy of vacuum liquid-absorbing automobile pot liquid that ball float is risen, valve body is opened, the pressure that balance vacuum liquid-absorbing vehicle tank is inside and outside, it is ineffective because ball float is subject to the interference of melt cinder in the vacuum liquid-absorbing automobile jar, this mode can not accurately be controlled liquid level sometimes, can not remind the operator to note liquid level information effectively.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of liquid level and alarm control unit of using on three-wheel vacuum liquid-absorbing automobile, the four-wheel vacuum liquid-absorbing automobile that adapt to is provided.
This practical technique scheme is achieved in that vacuum liquid-absorbing automobile liquid level and alarm control unit, is made up of solenoid valve, electric horn and Liquid level probe, and Liquid level probe is connected with electric horn with solenoid valve by lead; Solenoid valve and electric horn parallel connection are connected on the vacuum liquid-absorbing automobile battery positive voltage by lead, Liquid level probe is installed on the vacuum liquid-absorbing vehicle tank, when the vacuum liquid-absorbing automobile pot liquid contacts probe, circuit is connected, solenoid valve is opened, the pressure that balance vacuum liquid-absorbing vehicle tank is inside and outside stops imbibition in the vacuum liquid-absorbing automobile jar, and electric horn begins to report to the police simultaneously.
The utlity model has control level accuracy height, the characteristics of dependable performance.Can in time control liquid level in the vacuum liquid-absorbing automobile jar, provide liquid level information accurately for the operator simultaneously.
Description of drawings:
Accompanying drawing is the installation connection diagram of the utility model structure.
Among the figure: 1. solenoid valve, 2. electric horn, 3. Liquid level probe, 4. accumulator.
Embodiment:
As shown in drawings: vacuum liquid-absorbing automobile liquid level and alarm control unit, to form by solenoid valve 1, electric horn 2 and Liquid level probe 3, Liquid level probe 3 is connected with electric horn 2 with solenoid valve 1 by lead.Solenoid valve 1 and electric horn 2 parallel connections are connected on vacuum liquid-absorbing automobile accumulator 4 positive poles by lead, Liquid level probe 3 is installed on the vacuum liquid-absorbing vehicle tank, when the liquid level in the vacuum liquid-absorbing automobile jar touches probe, the power circuit conducting, solenoid valve and electric horn are started working, thereby control the height of vacuum liquid-absorbing automobile tank level accurately and report to the police.
