Abstract
The watertower limit switch is mainly applicable to roof watertower (tank) domestic building, which is characterized by that it possesses a sleeve, said sleeve is equipped with a water inlet and a water outlet, said water inlet is connected with water inlet pipe, in the interior of said sleeve a lift float is mounted, said lift float is connected with a drawbar in which there is a lower stop lever, and between the lift float and lower stop lever a floating ball is mounted. The invented watertower limit switch is simple in structure, easy to manufacture, and reliable in control effect.
Description
The present invention relates to water tower limit switch, mainly be applicable in the roof water tower or water tank of private residence.
Along with the increase of urban residence population, dwelling house is to high level or multilayer development.For the residential building of high level or multilayer in order to prevent tap water because hydraulic pressure etc. are former thereby cut off the water supply, so on the roof, have water tower or water tank more.Such water tower just must be installed level control switch for water.The level control switch for water of existing water tower adopts electrical equipment control usually, and therefore, existence makes trouble, and cost is higher, and defectives such as inconvenient, easy damage are installed.
The purpose of this invention is to provide a kind of mechanical, simple in structure, non-damageable water tower limit switch.
The technical scheme of water tower limit switch of the present invention is: a sleeve pipe is arranged, water inlet and water delivering orifice are arranged in the sleeve pipe, water inlet connects water inlet pipe, the lifting floating drum is installed in sleeve pipe, lifting floating drum cylinder lever connecting rod has lower stop lever in the pull bar, be equipped with ball float between lifting floating drum and lower stop lever.
Water tower limit switch of the present invention, the outer wall of its lifting floating drum are up-small and down-big cones.
Water tower limit switch of the present invention is equipped with pin in its pull bar, and ball float is positioned between the upper and lower pin.
Water tower limit switch of the present invention, upper and lower position of pin and lower stop lever is removable on it.
Water tower limit switch of the present invention is installed the elasticity clamping body in its casing wall, the elasticity clamping body matches with the lifting floating drum.
Water tower limit switch of the present invention, its described elasticity clamping body are spring and steel ball or spring leaf or rubber sheet gasket.
Water tower limit switch of the present invention connects rising pipe in the water delivering orifice of its sleeve pipe.
Water tower limit switch of the present invention is shaped on discharge orifice or gutter channel on the center of its lifting floating drum or the wall, make the water that enters in the sleeve pipe from the discharge orifice or gutter channel flow to the water tower.
The invention discloses a kind of water tower limit switch, compared with the prior art, have following characteristics: the one, adopt mechanical structure, durable in use; The 2nd, simple in structure, easy to manufacture, cost is low; The 3rd, sleeve pipe, floating drum, pull bar are in a straight line, and be along with fluctuation in stage, reliable for effect; The 4th, what of pondage in the water tower are the upper and lower spacing of pin and lower stop lever on the scalable determine; The 5th, the ball float heave amplitude is big in the water tower, and each inflow is many, reduces the starting of pump station number of times, prolongs the serviceable life of switch and pump.
Fig. 1 is a water tower limit switch structural representation of the present invention.
Below in conjunction with Fig. 1 embodiments of the invention are done detailed explanation.
The present invention mainly is the limit switch that is used for roof water tower or water tank, sleeve pipe 6 perpendicular to the water tower bottom is installed in water tower 9, it is guide pipe that sleeve pipe also cans be compared to, water inlet 10 and water delivering orifice 11 are arranged on the sleeve pipe 6, water inlet 10 connects water inlet pipe 8, can connect rising pipe 7 at water delivering orifice 11, also can uneasy rising pipe.Lifting floating drum 5 is installed in sleeve pipe, and lifting floating drum 5 cylinder lever connecting rods 2 have lower stop lever 1 in the pull bar 2, be equipped with ball float 3 between lifting floating drum 5 and lower stop lever 1.But also can be equipped with pin 4 in pull bar 2, buoyancy aid 3 is positioned between the upper and lower pin.And the upper and lower position of last pin 4 and lower stop lever 1 is removable.The lifting floating drum is a right cylinder, but for lifting floating drum 5 is moved smoothly in sleeve pipe 6, the outer wall of lifting floating drum 5 can be made up-small and down-big cone.When the water in the water tower 9 completely got up, ball float 3 come-ups were run into lifting floating drum 5 or are gone up pin 4 during work, promoted floating drum 5 by ball float 3 buoyancies and rose, and water inlet 10 and the water delivering orifice 11 that is opened on sleeve pipe 6 blocked, and discharging water stops.And use certain water level when water, when promptly decline of water table and ball float were run into lower stop lever 1 along with decline, because ball float has designed certain self gravitation, toward drop-down, floating drum 5 down broke away from water inlet 10, switch opens with pull bar 2.But in order to make ball float 3 not break away from water inlet 10 at once at the floating drum that surfaces on a small quantity, avoid being trapped in the state of a small amount of water inlet and continuous open and close, the elasticity clamping body can be installed in casing wall, the elasticity clamping body blocks lifting floating drum 5, have only when ball float during near full dew face, ball float gravity maximum, just floating drum is left behind, switch is opened entirely, be water inlet 10 standard-sized sheets, described elasticity clamping body is made up of spring and steel ball, perhaps spring leaf 12 chucking, and perhaps rubber sheet gasket etc. increases friction chucking etc.Can be for water is entered behind the sleeve pipe from following outflow, on the center system discharge orifice of lifting floating drum or wall, make gutter channel.
