Description
Technical field:
The utility model relates to a kind of water level in water pool control switch, especially a kind of water level in water pool control switch that utilizes ball float and rocking arm control switch assembly thereof to open or close intake tunnel and exhalant canal.
Background technique:
Tradition float-ball type level control switch for water, mainly by the base that has intake tunnel and exhalant canal, ball float and connecting rod thereof and the switching element that can open or close described intake tunnel and exhalant canal, displacement by switching element realizes switch motion, realize that described action must have bigger moment, therefore, the ball float of traditional float-ball type level control switch for water is bigger, and connecting rod is also long, make its manufacture cost higher, application and installation conditions also are restricted.Chinese patent 03225981.6 discloses a kind of float-ball type magnetic switch, and the switch block of this float-ball type magnetic switch utilizes magnetic, and there is a natural attraction between the sexes, principle of same-sex repulsion, thereby the ball float of its use is more much smaller than existing, connecting rod is much shorter also.Described float-ball type magnetic switch and traditional float-ball type level control switch for water are relatively, have greatly improved from consumptive material aspect tool, but its shortcoming is: because existing running water system generally adopts metallic water pipe, because the corrosion of metal often produces iron rust or iron filings in water quality, magnet in the magnetic switch can adsorb iron rust and iron filings, iron rust and iron filings accumulate in the water channel of magnetic switch, make switch block malfunctioning.For guaranteeing the normal use of described magnetic switch, must often unpick and wash magnetic switch, increase the difficulty of maintaining.
The model utility content:
The purpose of this utility model is to overcome the deficiency of existing float-ball type magnetic switch, provide a kind of simple in structure, volume is little, needn't often unpick and wash, the float-ball type baroswitch of long service life.
The utility model, comprise the base that has intake tunnel and exhalant canal, can open or close the switch block and the control unit of described intake tunnel and exhalant canal, control unit comprises ball float and rocking arm thereof, it is characterized in that: described switch block comprises the elastic switch pad that is arranged at intake tunnel and exhalant canal intersection, be arranged at the pad support on the elastic switch pad, and the sealed cap that the edge of elastic switch pad is pressed on the base inward flange, be provided with the water inlet micropore that communicates with intake tunnel in the bottom of pad support, above sealed cap, be provided with hold one's breath spilled water hole and extend pipeline section of exhaust, described sealed cap is anchored on it on base by end cap, end cap is provided with and extends the through hole that pipeline section matches, end cap is provided with hinged ear; rocking arm is hinged on the described hinged ear by bearing pin; in the front lower place of rocking arm; be provided with diaphragm seal, diaphragm seal can with the described exhaust spilled water hole involution mutually of holding one's breath.
The utility model, described control unit also comprises connecting rod, and an end of connecting rod is connected with ball float, and the other end is regulated with the rocking arm angle by nut and is connected.
The utility model, have that design science is reasonable, simple in structure, volume is little, needn't often unpick and wash, switch motion is fast, good sealing effect, never leak, characteristics such as long service life, can be widely used in the automatic control of various water level in water pool.
Description of drawings:
Accompanying drawing is embodiment's a structural principle schematic representation.Wherein Fig. 1 is " closing " state, and Fig. 2 is " open-minded " state, and Fig. 3 is the Q portion enlarged view of Fig. 1, and Fig. 4 is the A-A sectional view of Fig. 1.
Among the figure, 1, ball float 2, connecting rod 3, nut 4, Rocker arm 5, hinged ear 6, bearing pin 7, diaphragm seal 8, end cap 9, base 10, water inlet micropore 11, pad support 12, intake tunnel 13, exhalant canal 14, switch resilient pad 15, sealed cap 16, the exhaust spilled water hole of holding one's breath.
Embodiment:
With reference to accompanying drawing, this float-ball type baroswitch comprises the base 9 that has intake tunnel 12 and exhalant canal 13, switch block and the control unit that can open or cut out described intake tunnel and exhalant canal.Control unit comprises ball float 1, connecting rod 2 and Rocker arm 4, and an end of connecting rod 2 is connected with ball float 1, and the other end is connected with Rocker arm 4 is universal by screw and nut 3, but the height of free adjusting ball float, thus realize presetting of height of water level.Described switch block comprises the elastic switch pad 14 that is arranged at intake tunnel 12 and exhalant canal intersection, be arranged at the pad support 11 on the elastic switch pad, and the sealed cap 15 that the edge of elastic switch pad is pressed on base 9 inward flanges, be provided with the water inlet micropore 10 that communicates with intake tunnel in the bottom of pad support, above sealed cap, be provided with hold one's breath spilled water hole 16 and extend pipeline section 17 of exhaust, described sealed cap 15 is anchored on it on base by end cap 8, end cap is provided with and extends the through hole that pipeline section 17 matches, end cap 8 is provided with hinged ear 5; Rocker arm 4 is hinged on the described hinged ear 5 by bearing pin 6; front lower place of rocking arm; be provided with diaphragm seal 7, diaphragm seal can with described exhaust spilled water hole 16 involution mutually of holding one's breath.
The utility model is used when being installed in the pond, its working principle is: when drawdown ball float 1 also descends thereupon, connecting rod 2 drives Rocker arm 4 and does counterclockwise to rotate around bearing pin 6, the exhaust this moment spilled water hole 16 of holding one's breath is opened, the pressure of the cavity B that is made of sealed cap 15 and switch resilient pad 14 equates with atmosphere, be the pressure of the interior pressure of cavity B less than hydraulic pressure, under the effect of hydraulic pressure, switch resilient pad 14 is lifted, thereby opened the passage of intake tunnel 12 and exhalant canal 13, to the pond water-filling, promptly switch is in opening state, as shown in Figure 2; When the water level in the pond rises and when driving ball float 1 and being raised to certain water surface, connecting rod 2 drives Rocker arm 4 and does the clockwise direction rotation around bearing pin 6, diaphragm seal 7 envelopes below before rocking arm 6 are pushed down the exhaust spilled water hole 16 of holding one's breath, be that the exhaust spilled water hole 16 of holding one's breath is closed, because the effect of the spring-back force of switch resilient pad 14, tap water slowly enters cavity B by water inlet micropore 10, pressure until cavity B equates with the hydraulic pressure of tap water, because the pressure of exhalant canal equates with atmospheric pressure, therefore the pressure in the cavity B is greater than atmospheric pressure, switch resilient pad 14 is closely attached on the inlet of exhalant canal, promptly closed exhalant canal 13, stop to the pond water-filling, promptly switch is in closed condition, as shown in Figure 1.
