Specific implementation mode
Embodiment 1：
Please refer to Fig.1~3, in the embodiment of the present invention, a kind of extension type floating ball liquid level control device, including blowdown puddle 1 and
The supporting frame 2 being fixedly mounted on 1 edge of blowdown puddle, supporting frame 2 include longitudinal rod 201, the second transverse bar 202 and the
Two transverse bars 203, the second transverse bar 202 and the second transverse bar 203 are fixedly connected on longitudinal rod 201 by welding respectively
A side on, the second transverse bar 202 is located at the top position of the second transverse bar 203, is leaned on a side of longitudinal rod 201
The lower position of nearly second transverse bar 202 is installed with the high limit switch 3 of liquid level, and a side of longitudinal rod 201
The upper lower position close to the high limit switch of liquid level 3 is installed with liquid level lower bound bit switch 4, the high limit switch of liquid level
There are one opened points for 3 settings, and there are one normally closed point, the second transverse bar 202 and second is lateral for setting on liquid level lower bound bit switch 4
It is fixedly connected with casing 5 in the compression end of bar 203 by welding, the inside of casing 5 is through be movably set with can be into
The gonnecting rod body 6 that moves up and down of row, gonnecting rod body 6 are a kind of component of stainless steel, and the outer surface of gonnecting rod body 6 be coated with it is wear-resisting
Material, wear-resistant material are a kind of component of potassium steel material, and the bottom end of gonnecting rod body 6 is installed with floating ball 7, the appearance of floating ball 7
Face is coated with anti-corrosion layer, and anti-corrosion layer paints for a kind of water proofing property, and the top of gonnecting rod body 6 is limited through spacing bayonet lock 9 is connected with
The length of position bayonet lock 9 is more than the outer diameter of casing 5, and the outer surface of spacing bayonet lock 9 is connected with protective jacket by strength glue bond, even
The center outer surface pivot bush unit of the body of rod 6 be useful for the high limit switch 3 of triggering liquid level and liquid level lower bound bit switch 4 whether work
Make, and the stroke limit block 8 of adjustable height, stroke limit block 8 is when following gonnecting rod body 6 to move up and down, stroke limit block 8
One end can be in contact with the trigger point of any one in the high limit switch 3 of liquid level and liquid level lower bound bit switch 4, liquid level is high
One limit switch 3 and liquid level lower bound bit switch 4 are serially connected in the circuit of 380VAC.
Embodiment 2：
Fig. 4~5 are please referred to, a kind of extension type floating ball liquid level control device can control the more pump housings and work, with embodiment
1 different place is：It is located at the second transverse bar 202 and the high limit switch of liquid level 3 on a side surface of longitudinal rod 201
