The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: intake pipe 1; Valve body 2; Spool 3; Valve rod 4; Supporting frame 5; Bearing pin 6; Pull bar 7; Float 8; Float localization frame 9; Aqua storage tank 10.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of liquid-level auto-control device, comprise intake pipe 1, valve body 2, spool 3, valve rod 4, supporting frame 5, bearing pin 6, pull bar 7, float 8, float localization frame 9 and aqua storage tank 10, the upper end of described valve body 2 is connected with intake pipe 1, spool 3 is arranged on the inboard of valve body 2, spool 3 is connected with valve rod 4, the lower end of valve body 2 is provided with osculum, bearing pin 6 has two, the osculum that the valve rod 4 that spool 3 connects passes valve body 2 bottoms is connected with an end of pull bar 7 by bearing pin 6, one side of the middle part of pull bar 7 deflection spool 3 is connected by the supporting frame 5 be connected on bearing pin 6 and valve body 2, the other end of pull bar 7 is connected with float 8, float 8 is arranged in float localization frame 9, float localization frame 9 is fixedly installed on the inside of aqua storage tank 10.
The inboard of described valve body 2 lower end osculums is provided with sealing surface, and spool 3 is provided with sealing surface and sealing surface is downward and sealing surface valve body osculum inboard is complementary, and the external diameter of spool 3 is greater than the diameter of osculum, is less than the internal diameter of valve body 2.
Described bearing pin 6 is provided with free rotational structure.The effect of bearing pin 6 can not separate pull bar 7 and valve rod 4, supporting frame 5, but can meet the needs that freely rotate, and is equivalent to the fulcrum of lever.
Described intake pipe 1 is bent downwardly and is 90 degree, and valve body 2 is connected to each other by flange or screw thread with intake pipe 1.
The end that described pull bar 7 is connected with float 8 is bent downwardly, and reclinate angle is 90 degree or approximate 90 degree.
Described spool 3 be shaped as any one in T shape, taper or plane.
Principle of the present utility model is: the gravity and buoyancy and the lever principle that rely on float, rising and reduction along with liquid level, float moves up and down with height of liquid level, be subjected to buoyancy and Action of Gravity Field, the suffered active force of pull bar one end that float connects changes, and then move up and down with float, by pull bar, be delivered to the other end of pull bar by the effect of fulcrum, the other end of pull bar also moves up and down thereupon, the valve rod band movable valve plug that the pull bar the other end connects moves up and down, realize that closing of water source is disconnected and open, and then realizing the automatic regulation and control of liquid level.
In use, when the water level in aqua storage tank 10 descends, float is subjected to acting on of gravity drives the pull bar 7 connected in the float localization frame a side automatically to produce the active force moved down, the bearing pin 6 that this active force is connected with supporting frame 5 by pull bar 7 and pull bar 7 is delivered to the opposite side of pull bar 7, the opposite side of pull bar 7 produces the active force oppositely made progress, by valve rod 4 band movable valve plugs 3, move up, the sealing surface of spool 3 bottoms separates automatically with the sealing surface of valve body 2 lower inside, the water with certain pressure in intake pipe 1 flows out by the osculum of valve body 2 bottoms through the annular space between spool 3 and valve body 2 again, automatically give aqua storage tank 10 moisturizings.
Otherwise when the water level of aqua storage tank is raised to certain altitude, the sealing surface auto-closing of the sealing surface of spool 3 bottoms and valve body 2 lower inside, moisturizing stops automatically.
The utility model is compared and is extended working life more than one times with traditional float-type liquid level controller, can be used for the automatic control of the water levels such as tank, water tank, container, flush toilet, also the automatic control of liquid of available soda acid, salt, other class I liquid Is of wet goods.
