Abstract
A swinging pilot-controlled switch relates to the technical filed of switches, and comprises a rotatable annular sealed container, wherein conductive liquid and insulating liquid which have differentspecific 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 upper end of the rotatable annular sealed container is connected with a support bar, the top end of the support bar is provided with a shaft, and the rotatable annular sealed container can swing around the shaft. The swinging 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 swung 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 hydraulic control switch of swinging, 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 upper end is connected with support bar, supporting bar top is provided with axle, and rotatable annular closed container can be swung around axle.
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 that the utility model can be swung the hydraulic control switch.
Embodiment
Below in conjunction with accompanying drawing the utility model is specified, as shown in Figure 1, a kind of hydraulic control switch of swinging, comprise rotatable annular closed container 1, conducting liquid 2 and iknsulating liquid 3 that rotatable annular closed container is equipped with the proportion difference, can separates up and down are fixed with positive terminals 6 and negative terminals 7 on described rotatable annular closed container 1 inwall, and rotatable annular closed container 1 upper end is connected with support bar 5, support bar 5 tops are provided with axle 4, and rotatable annular closed container 1 can be around axle 4 swings.
When swinging the 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 swinging the hydraulic control switch when axle 4 flips an angle, conducting liquid 2 contacts with binding post 6,7, connects binding post 6,7, and switch begins conduction; In the time can swinging the hydraulic control switch and turn over conducting liquid 2 scopes, circuit is insulated liquid 3 again and disconnects.This can be swung the hydraulic control switch and have explosion-proof performance preferably.
Claims (1)
1, a kind of hydraulic control switch of swinging, comprise rotatable annular closed container (1), conducting liquid (2) and iknsulating liquid (3) that rotatable annular closed container is equipped with the proportion difference, can separates up and down, 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) upper end is connected with support bar (5), support bar (5) top is provided with axle (4), and rotatable annular closed container (1) can be swung around axle (4).
