Embodiment
As shown in Figure 1, this external water-level control apparatus is connected with feed pipe 2, return pipe 3, filling pipe 4 on the cooling tower 1, also be provided with an overflow pipe 19 in the cooling tower 1; Cooling tower is provided with two aqua storage tanks outward, and two aqua storage tanks are connected on the return pipe 3 of cooling tower by a water pipe 7, two aqua storage tanks are respectively high water stage aqua storage tank 5, low-water level aqua storage tank 6, and two aqua storage tanks and water pipe 7 junctions are provided with high water stage aqua storage tank valve 51, low-water level aqua storage tank valve 61, be handled easily, the optional solenoid valve of using of two valves.
The water-level float device of being made up of ball float 8, vertical slide bar 9, top shoe 10, sliding block 11 is installed in two aqua storage tanks, ball float 8 cross-under are on slide bar 9, ball float 8 can slide up and down on slide bar 9, top shoe 10, sliding block 11 be screwed respectively above the ball float 8 and below slide bar 9 on, two slide blocks play position-limiting action to the position of ball float 8 on slide bar 9, and the position of two slide blocks on slide bar 9 can up-down adjustment.
The top of water-level float device is by the fixing water level controller 12 of fixed mount, water level controller 12 comprises relay spool 121, magnet 124, front plate 122, rear plate 123, the middle part of the bottom bearing pin 14 hinged horizontal levers 13 of water level controller, make lever 13 and bearing pin 14 form a leverage, one end of lever 13 is hinged on the top of slide bar 9, the other end of lever 13 is installed a balancing weight 15, this balancing weight 15 can be on lever 13 shift position, lever 13 is provided with and its axial vertical fork 16, magnet 161 is equipped with on fork 16 tops, also be provided with left pawl 162 on the fork 16, right pawl 163 is seen Fig. 2.The top of the relay spool of two water level controllers is provided with two contacts.
Filling pipe is provided with a water compensating valve 17, this water compensating valve 17 is a solenoid valve, coil one end of solenoid valve connects zero line, the coil other end connects the contact B of the water level controller of low-water level aqua storage tank, the contact B of this water level controller connects the contact B ' of another water level controller, the contact A of this water level controller connects the contact A of another water level controller ', and connect live wire.
Its principle of work and step are as follows: when in the cooling tower 1 water being arranged, water will be entered in two aqua storage tanks by the water pipe 7 of return pipe 3 and connection return pipe 3, water in the cooling tower 1 and the water level in two aqua storage tanks remain balance, when the decline of water table in the cooling tower 1, water level in the aqua storage tank also descends thereupon, ball float 8 in the aqua storage tank descends thereupon, if also continue to descend move downward the sliding block of running on the slide bar 9 11 when ball float 8 after, slide bar 9 can drive lever 13 motions, fork 16 on the lever 13 is swung left from the right side, right pawl 163 on fork 16 is run into the edge of water level controller rear plate 123, the magnet 161 on fork 16 tops is approaching with the magnet 124 on the water level controller relay spool simultaneously, because two magnet magnetic poles are relative, the repulsion so meet, making relay spool 121 move up contacts with two contacts of top, the coil of the water compensating valve 17 on the filling pipe 4 gets, spool and its valve seat break away from, current safeguard that through adjusting valve 18 flows in the cooling tower 1 by filling pipe 4, has realized moisturizing.
In the moisturizing process, water level in cooling tower 1 and two aqua storage tanks rises simultaneously, ball float 8 in the aqua storage tank also moves up thereupon, after running into top shoe 10 on the slide bar 9, ball float 8 tops also continue moisturizing, ball float 8 will drive slide bar 9 and move upward, slide bar 9 can drive lever 13 motions, fork 16 on the lever 13 is swung to the right, left pawl 162 up to fork 16 contacts with the edge of the front plate 122 of water level controller, the magnet 161 on fork 16 tops and the magnet 124 on the water level controller relay spool stagger mutually at this moment, relay spool 121 falls, disconnect with two contacts of its top, water compensating valve 17 coil losing electricities on the filling pipe 4, water compensating valve 17 is closed, and moisturizing finishes.
The purpose that two aqua storage tanks are set is: an aqua storage tank breaks down in the time of can not working therein, and another aqua storage tank can work on, thereby has guaranteed the operate as normal of total system.
During work,, two valves 51,61 of two aqua storage tanks and water pipe 7 junctions are all opened if when cooling tower 1 is driven an ebullator.When cooling tower 1 was driven two ebullators, the valve 51 that connects the high water stage aqua storage tank must be closed, and does not allow high water stage aqua storage tank 5 and high water stage liquid level controller work, and avoided moisturizing in advance.
When adjusting water level, need first ON cycle water pump, realize by the slide block of regulating on the slide bar 9 up and down 10,11 again,, move on the position of slide block, then move on the range of movement of ball float 8, raise so set up water level according to the position of the gap of cooling tower; The position of opposite slide block descends, and sets up water level and reduces; Stop water behind the ebullator and can't help the gap of overflow pipe 19 and overflow, illustrate that regulating is the optimum position.
When two or more cooling towers are shared, only need solenoid valve coils from parallel connection of coils on the filling pipe of the coil of solenoid valve on the filling pipe of other cooling towers and first cooling tower is got final product.
As other embodiments: can directly connect a water pump on the filling pipe, also can reach same effect.
