Abstract
A drive-type pilot-controlled switch relates to the technical field of switches, and comprises a rotatable annular sealed container, wherein conductive liquid and insulating liquid which have different specific gravities, and can separate up and down are filled in the rotatable annular sealed container, a positive connecting end and a negative connecting end are fixed on the inner wall of the rotatable annular sealed container, the rotatable annular sealed container is connected on a shaft through a support bar, the rotatable annular sealed container can rotate around the shaft, the outer side of the rotatable annular sealed container is close to the outer side of a rotary table, and a shaft of the rotary table is connected with a drive shaft of a motor. The drive-type pilot-controlled switch has better explosion-proof performance.
Description
Technical field
The utility model relates to a kind of electric switch, a kind of specifically liquid level control switch that utilizes liquid flow control circuit break-make.
Background technology
At present, existing switch has standard machinery formula contact switch, optoelectronic switch, air switch etc., and explosion-proof performance is bad, and the switch of the break-make that flows control circuit of utilizing liquid is seldom arranged on the market, and liquid control switch we can say on market it is less.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and utilizes the upset of object to make liquid flow realize the drive-type hydraulic control switch of the automatic road of circuit break-make, has explosion-proof performance preferably.
The utility model is finished by the following technical programs: a kind of drive-type hydraulic control switch, comprise rotatable annular closed container, rotatable annular closed container is equipped with proportion difference, the conducting liquid that can separate up and down and iknsulating liquid, be fixed with positive terminals and negative terminals on the described rotatable annular closed container inwall, rotatable annular closed container is connected on the axle by bracing frame, rotatable annular closed container can sway, the outside of rotatable annular closed container is near the rotating disk outside, and the axle of rotating disk is connected with the driving shaft of motor.
The beneficial effects of the utility model are: utilize liquid flow to realize the break-make of control circuit, have explosion-proof performance preferably.
Description of drawings
Fig. 1 is the structure chart of the utility model drive-type hydraulic control switch.
Embodiment
Below in conjunction with accompanying drawing the utility model is specified, as shown in Figure 1, a kind of drive-type hydraulic control switch, comprise rotatable annular closed container 1, rotatable annular closed container is equipped with the proportion difference, conducting liquid 2 that can separate up and down and iknsulating liquid 3, be fixed with positive terminals 6 and negative terminals 7 on described rotatable annular closed container 1 inwall, rotatable annular closed container 1 is connected on the axle 4 by bracing frame 5, rotatable annular closed container 1 can rotate around axle 4, the outside of rotatable annular closed container 1 is near rotating disk 8 outsides, and the axle of rotating disk 89 is connected with the driving shaft of motor.
During use, because the axle 9 of rotating disk 8 is connected with the driving shaft of motor, the driving shaft of motor can drive rotating disk 8 and rotate, because the outside of rotatable annular closed container 1 is near rotating disk 8 outsides, therefore, rotating disk 8 drives rotatable annular closed container 1 rotation.
When drive-type hydraulic control switch at horizontal level, as shown in Figure 1, conducting liquid 2 disconnects with binding post 6,7, and is non-conductive.When drive-type hydraulic control switch when axle 4 flips an angle, conducting liquid 2 contacts with binding post 6,7, connects binding post 6,7, switch begins conduction; When drive-type hydraulic control switch turned over conducting liquid 2 scopes, circuit was insulated liquid 3 again and disconnects.This drive-type hydraulic control switch has explosion-proof performance preferably.
Claims (1)
1, a kind of drive-type hydraulic control switch, comprise rotatable annular closed container (1), rotatable annular closed container is equipped with the proportion difference, conducting liquid that can separate up and down (2) and iknsulating liquid (3), it is characterized in that: be fixed with positive terminals (6) and negative terminals (7) on described rotatable annular closed container (1) inwall, rotatable annular closed container (1) is connected on the axle (4) by bracing frame (5), rotatable annular closed container (1) can rotate around axle (4), the outside of rotatable annular closed container (1) is near rotating disk (8) outside, and the axle (9) of rotating disk (8) and the driving shaft of motor are connected.
