Description
Technical field
The utility model relates to a kind of switch gear, is the switch of the automatic control water level of a kind of energy specifically.
Background technique
The water level switch that uses mainly comprises ball float, lever, valve body, needle at present, utilizes the buoyancy of ball float to drive shutoff and the disconnection that the lever pushing needle is realized needle and valve body, realizes the control water inlet from you.This mode water level control range is little, and water level reduces less, has just opened valve inleting water, and the water that reach certain consumption will strengthen the water tank volume, can not effectively utilize the water tank space.
Summary of the invention
The purpose of this utility model provides big, simple in structure, the easy for installation automatic water level switch of a kind of water level control range.
The technological scheme that the utility model is adopted is: this automatic water level switch is arranged in the water tank, comprise ball float, valve, pull bar, described pull bar vertically is installed on the fixed support, fixed support is installed on the water tank wall, pull bar can move up and down along fixed support, described ball float is the airtight cavity that the middle part is provided with through hole, pull bar was scurried the through hole of ball float, ball float can move up and down along pull bar, on the pull bar between ball float and two fixed supports, the even locating stud that is provided with in the above and below of ball float, one end of described pull bar is connected with valve, also can be connected electrical switch control of pump start-stop with electrical switch.
Be provided with afterburning switch between locating stud above the described ball float and fixed support, this reinforcing switch one end is fixed on the water tank wall, and the other end contacts with pull bar, on pull bar and with afterburning switch touching position, be provided with the extension lever that two ends are taper.
Described ball float can increase balancing weight, is the ball float of band counterweight.
Because pull bar of the present utility model is vertically to be arranged in the water tank, ball float can move up and down and move up and down by locating stud moving pull bar of generation along pull bar, and the scope of water level control is big; And can regulate the setting of high low water level by distance and two support bracket fastened distances of setting of setting two locating studs, use flexibly; It is when guaranteeing that buoyancy or lower pulling force reach certain value that this device is provided with afterburning switch and extension lever, could move up and down by pushing drawing rod.
Description of drawings
Fig. 1 is a schematic representation of the present utility model
Embodiment
Automatic water level switch of the present utility model, be arranged in the water tank 1, comprise ball float 2, valve 3, pull bar 4, described pull bar 4 vertically is installed on the fixed support 5, fixed support 5 is installed on the water tank wall, and can move up and down along fixed support 5, described ball float 2 is provided with the airtight cavity of through hole for the middle part, pull bar 4 was scurried the through hole of ball float 2, ball float 2 can move up and down along pull bar 4, on the pull bar 4 between ball float 2 and two fixed supports 5, the even locating stud 6 that is provided with in the above and below of ball float 2, one end of described pull bar 4 (upper end or lower end) is connected with valve 3, also can be connected with electrical switch.Can be as required valve 3 or electrical switch be arranged on the top or the bottom of water tank, do to be connected accordingly with pull bar 4.
Between locating stud 6 above the described ball float 2 and the fixed support 5 above the ball float 2, be provided with afterburning switch 7, these reinforcing switch 7 one ends are fixed on the water tank wall, the other end contacts with pull bar 4, on pull bar 4 and with afterburning switch 7 touching positions, being provided with two ends is the extension lever 8 of taper.Afterburning switch 7 can also be arranged on the fixed support 5 with pull bar 4 touching positions, make one with fixed support 5 and also can.
Can increase balancing weight at the following of ball float 2, both ball float 2 was the ball float of band counterweight.
Automatic water level switch of the present utility model is realized the scope of control water level by the position that two locating studs 6 are set, during use, when water level begins to reduce, pull bar 4 is motionless, can not start valve 3 water inlets, ball float 2 moves down with the water level reduction along pull bar 4, when water level drops to certain low level, both ball float 2 was reduced to locating stud 6 places of below, at this moment water level continues to reduce, and ball float 2 will reduce with water level, adds the effect of balancing weight, by pressing locating stud moving pull bar 4 of 6 generations to move down, the valve 3 that is connected with pull bar 4 just can be opened water inlet; When valve 3 begins water inlet, make water level begin to raise, at this moment pull bar 4 is still motionless, valve 3 can not stop into water, and ball float 2 can rise with water level along pull bar 4 and move up, when to certain when high-order, when both ball float 2 rises to locating stud 6 places of top, ball float 2 can drive pull bar 4 by locating stud 6 and move up, and the valve 3 that is connected with pull bar 4 will be closed then, stops into water.
Between locating stud above the ball float 26 and fixed support 5, be provided with afterburning switch 7, extension lever 8 is set on pull bar 4, when pull bar 4 when moving up and down, the tapered end of the extension lever 8 that is provided with on the pull bar 4 contacts afterburning switch 7, has only the buoyancy of pull bar 4 or when down thrust reaches certain value, just the elasticity bulb of afterburning switch 7 front ends inwardly can be pushed up, pull bar 4 just can be smoothly by going up or motion down of doing to continue.
Pull bar also can drive electrical switch, as position limit switch.When water level attained to a high place, electrical switch disconnected, and water pump stops.When water level is reduced to low level, electrical switch closure, starting mode of pump
Automatic water level switch of the present utility model can pass through to regulate two positions of alignment pin on pull bar, Realize controlling the scope of water level, have and use flexibly characteristics simple in structure, easy for installation.
