Abstract
The utility model discloses an electrically controlled device related to water tank and cursory valve, it comprises motor, gear reduction box, hoist wheel, mud dragon rope, tension switch, limit switch etc. and it changes into the cursory valve that originally can only control its valve switching by cursory buoyancy and can not only lean on its valve switching of signal of telecommunication control, also can lean on the cursory buoyancy of former cursory to control the switching of its valve. The effect opens up a new way for the electric control of the float valve.
Description
The utility model is and water tank and the relevant electric controller of cursory valve.
Present cursory valve is to act on cursory going up valve closing by buoyancy of water, and the pressure that leans on water in the grid is with valve open.
The purpose of this utility model is to increase an electrically switchable grating control valve unit on the basis of existing cursory valve, makes cursory valve can adopt buoyancy control also can adopt electronic control.
The utility model is to realize like this, motor (1) drives elevator wheel (3) by gear reduction box (2), fix a linear flexible body (4) on the elevator wheel (3), behind the elastic arm (5) and the pulley (8) of limit switch of linear flexible body (4) by a tension switch, the other end is fixed on cursory valve in the water tank cursory or on the arm of force.
Extremely long-pending effect of the present utility model is that it is transformed into the cursory valve that can only lean on cursory buoyancy to control its valve opening and closing originally can control its valve opening and closing by electrical signal, also can lean on former cursory buoyancy to control the switching of its valve.When the electrical signal that sends made linear flexible body be in relaxed state, the switching of cursory valve was by cistern water level and cursory buoyancy decision.When the electrical signal that sends makes linear flexible body be in tension, no matter in the water tank whether water is arranged, cursory valve is in closed condition, and electrical signal has precedence over the control of cursory buoyancy to cursory valve opening and closing to the control of cursory valve opening and closing like this.This effect be the electronic control of cursory valve split one newly by way of.
For more clearly expressing the utility model, describe preferred embodiment of the utility model below with reference to accompanying drawings in detail:
Fig. 1 is that the utility model is with the schematic representation under the float valve door closure state.
Fig. 2 is that the utility model is with the schematic representation under the cursory valve open mode.
Describe concrete formation of the present utility model and working condition in detail below in conjunction with Fig. 1.
Motor (1) drives elevator wheel (3) by gear reduction box (2), fix a mud dragon rope (4) of not having a stretchability on the elevator wheel (3), mud dragon rope (4) passes the rope through on the tension switch elastic arm (5), is fixed on cursory (12) by pulley (8) the back the other end again.
(13) be the cursory arm of force, (14) are cursory valve intake pipes, and (15) are water tanks.
(5) and (7) form a tension switch, electric control mechanism opens the signal of cursory valve to motor (1) transmission by this switch.
(5) be the conductive elastic arm that has a rope through with the upper end that thin Stainless Steel Wire is made, (7) be the thin hollow cylinder made from conductive material, (5) pass from the center of (7), when mud dragon rope (4) is in relaxed state as Fig. 2 is drawn, elastic arm (5) does not stress, and (5) and (7) do not have point of contact; When mud dragon rope (4) is in tension as Fig. 1 is drawn, (5) bending makes (5) and (7) point of contact occur, (5) and (7) have just formed a tension switch like this, when mud dragon rope (4) when being in relaxed state switch disconnect, when mud dragon rope (4) switch connection when being in tension.
(11) be the self-resetting switch of a normally off.Electric control mechanism transmits the signal of closing cursory valve by self-resetting switch (11) to motor (1).
The pulley arm of force (6), contact (10), pulley (8), spring (9), self-resetting switch (11) constitute a limit switch.The elastic force of spring (9) is taken turns the maximum tension that can export greater than closing the required lowest pull of cursory valve less than elevator.After motor (1) receives the signal of cutting out cursory valve, drive elevator wheel (3) by gear reduction box (2) and tighten up mud dragon rope (4), this moment cursory (12) is to top offset, when moving to after the cursory valve of limit position effectively closes, tension force on the mud dragon rope (4) strengthens gradually, when tension force during greater than the elastic force of spring (9), pulley (8) is to bottom offset, the pulley arm of force (6) serves as axially rotation down with the A point, after contact (10) is pressed self-resetting switch (11), self-resetting switch becomes disconnection by conducting, cuts off the control signal of motor (1), and motor (1) quits work.
Claims (3)
1, a kind of cursory valve electric controller of controlling the cursory valve of water tank is characterized in that driving elevator wheel (3) by motor (1) by gear reduction box (2) one of increase on the water tank drives the control gear that the linear flexible body (4) that is fixed on cursory or the float pole is controlled cursory valve opening and closing.
2, cursory valve electric controller according to claim 1 is characterized in that linear flexible body (4) by behind the elastic arm (5) of a tension switch, and the other end is fixed on the cursory last or arm of force of cursory valve in the water tank.
3, cursory valve electric controller according to claim 1 is characterized in that linear flexible body (4) by behind the pulley (8) of a limit switch, and the other end is fixed on the cursory last or arm of force of cursory valve in the water tank.
