Abstract
The utility model discloses a liquid level initial pipeline on-off control device. It comprises of the floating body, valve and stop block. The floating body is installed on the driving arm of the lever; the gear frame of the valve revolves within the movement scope of the resistance arm of the lever or joins with the rotational axis of the valve and the lever at the pivot point; the stop block is installed on the motion trajectory of the floating body, lever or the gear frame of the valve. This utility model, with pure mechanical structure, leaves out the configuration of complicated electric system and frees from the reliance on electric power. Therefore, the utility model, with the advantages of excellent safety and energy-saving performance, simple structure, stable performance and low cost, is appropriate for promotion on large scale.
Description
Technical field
The utility model is the device about the pilot line break-make, and is especially a kind of according to the device of liquid level change from the main control pipeline break-make.
Background technique
At present, known liquid level independence pipeline on-off system is made up of float-ball type magnetic level switch, control power supply and electric wire, relay, solenoid valve, electrical source of power and electric wire, its constituted mode is, float-ball type magnetic level switch is installed to the correct position of liquid level change, its circuit is connected in series on the control coil of control power supply and relay, solenoid valve is installed on the pipeline that will control, and the coil of solenoid valve is connected in series on the contact of electrical source of power and relay.When liquid level change, float-ball type magnetic level switch will connect or disconnect, relay will be because of control coil energising or outage or outage and adhesive or unclamp, the contacting of relay or disconnection, solenoid valve will be started working or quit work because of coil electricity or outage, thereby finish automatic control to the pipeline break-make, said apparatus is by float-ball type magnetic level switch, control power supply and electric wire, relay, solenoid valve, electrical source of power and electric wire are formed, complex structure, if wherein any one link is out of order and will causes system to operate, unstable properties, its electrical source of power often belongs to dangerous voltage, dangerous, add higher this device that makes of its cost and popularize relatively difficulty in daily life.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of safe, energy-conservation, simple in structure, stable performance, with low cost is provided, the liquid level independence pipeline on-off system that is suitable for popularizing.
In order to solve the problem of above-mentioned existence, the utility model has adopted following technical proposals: buoyancy aid is contained on the power arm of lever, the gear frame of valve is in the range of movement of lever resistance arm strength, or the rotatingshaft of rotating valve is connected at the fulcrum place with lever, and limiting stopper is contained on the movement locus of buoyancy aid or on the movement locus of lever or on the movement locus of valve gear frame; The moment that buoyancy aid is produced by the moment that produces behind the buoyancy and self gravitation in liquid is even more than or equal to opening or closing the required moment of valve; When limiting stopper 4 and limiting stopper 5 are installed in normal opening and closing valve respectively the upper and lower bound of buoyancy aid or lever or valve gear frame motion more arbitrarily.
Owing to adopted technique scheme, the liquid independence pipeline on-off system that the utility model provides have following beneficial effect, safe, energy-conservation, replaced original complicated electrical system by buoyancy aid, lever and limiting stopper, simple in structure, stable performance, with low cost.
Description of drawings
A kind of enforcement structural representation when Fig. 1 is the utility model employing sliding shutter;
A kind of enforcement structural representation when Fig. 2 is the utility model employing ball valve;
Fig. 3 is that the utility model adopts lever directly is contained in enforcement structural representation on the rotatingshaft of ball valve.
The gear frame of 1 buoyancy aid, 2 levers, 3 valves, 4 limiting stoppers, 5 limiting stoppers among the figure.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
When liquid constantly consumes or discharge liquid level when descending, buoyancy aid 1 also descends thereupon, and under the effect of lever 2 and gear frame 3, gradually valve open, when liquid level drops to limiting stopper when following, valve reaches maximum, and buoyancy aid is subjected to limiting stopper 4 restrictions to be stopped to descend; Liquid constantly injects from valve, and liquid rises, and buoyancy aid is also along with rising, and valve is turned down gradually, valve complete shut-down when the liquid level rising makes buoyancy aid near limiting stopper 5.
Claims (3)
