Above-mentioned purpose of the present utility model realizes by following technical proposals, that is:
Ball float level controller comprises ball float assembly, housing and throw-over gear.The ball float assembly comprises ball float and connecting rod.Ball float is fixedlyed connected with an end of connecting rod, and the other end of connecting rod is fixed with magnet steel.Housing comprises front end end cover, cylindrical shell and rear end cap.Front end end cover is connected with an end solid welding of cylindrical shell, and the other end of cylindrical shell connects with rear end cap with screw thread after loading onto sealing gasket.Solid welding is connected with the connecting rod casing on the front end face of front end end cover, and the front end of connecting rod inserts in the connecting rod casing, and connecting rod connects by bearing pin and connecting rod casing.Throw-over gear is principal character part of the present utility model.Throw-over gear comprises fixed body, microswitch, fixing side bucket, swing arm and protective cover.Wire through-hole is arranged on the fixed body.The bucket chamber, the front end side of having of fixed body.Fixed body is packed in the housing, and fixedlys connected with inner walls.The rear end of fixed body is fixed with gland, is fixed with connection terminal on gland.Side's bucket of fixing square barrel bottom insertion fixed body front end is indoor, and protective cover is sleeved on to be fixed on square barrel, and the rear end of protective cover is connected with the fixed body solid welding.Microswitch is installed in the rear end in the fixing side bucket, swing arm connects by bearing pin and fixing side bucket, the rear end of swing arm can contact with a contact of microswitch, the other end is fixed with magnet steel, the rear end magnetic of the magnet steel on the front end magnetic of this magnet steel and the connecting rod of ball float is identical, 3 binding posts of microswitch are connected with 3 binding posts of connection terminal respectively by lead, and lead can stretch out outside the housing by the cable through-hole on the housing sidewall.
Here be noted that the ball float assembly is a known technology, can adopt known various forms of ball float assemblies at present.
The utility model is applicable to the upper limit or the lower limit warning of various liquid levels in uncovered or the closed container, cooperates with operation circuit, can realize the position formula control of liquid level.The utility model is specially adapted to use in marine ship and the naval vessels.
Use this ball float level controller, when tested liquid level changes, ball float is just upper and lower thereupon to be moved, ball float is upper and lower to be moved the magnet steel make its interlinking lever end and does reverse direction and move, when reaching two reference mark of liquid level, repulsive interaction by same sex magnetic force, make the magnet steel of the swing arm front end in the throw-over gear the opposing party that is ostracised rapidly, thereby drive the swing arm motion, the contact of extruding or release microswitch, make it and contacting or disconnection, output switching signal is in order to realize warning or control.
The utlity model has following advantage:
1, because throw-over gear parts simple in structure, that use are few, so volume little (few more than a times according to like product), cost low (cost is low more than 2 times according to like product);
2, between throw-over gear and ball float no mechanical transmission and stroke short, separate so flexible movements, reliable operation, long service life fully with fluid to be measured;
3, cylinder back-end connects good seal performance with screw thread and rear end cap after loading onto sealing gasket.
