Abstract
A pendulum pilot-operated switch relates to the technical field of switches, which comprises a rotatable annular closed container. Conducting liquid and insulating liquid which have different proportions and can be separated up and down are filled in the rotatable annular closed container, a positive wiring terminal and a negative wiring terminal are fixed on an inner wall of the rotatable annular closed container, the upper end of the rotatable annular closed container is connected with a supporting rod, the top end of the supporting rod is equipped with a shaft, and the rotatable annular closed container can swing around the shaft which is fixed on a supporting base. The pendulum pilot-operated switch has relatively fine anti-explosion property.
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 pendulum model 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 pendulum model 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 upper end is connected with support bar, supporting bar top is provided with axle, and rotatable annular closed container can be swung around axle, and axle is fixed on the bearing.
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 pendulum model hydraulic control switch.
Embodiment
Below in conjunction with accompanying drawing the utility model is specified, as shown in Figure 1, a kind of pendulum model hydraulic control switch, 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, 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 tops are provided with axle 4, rotatable annular closed container 1 can be around axle 4 swings, and axle 4 is fixed on the bearing 8.
When pendulum model 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 pendulum model 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 pendulum model hydraulic control switch turned over conducting liquid 2 scopes, circuit was insulated liquid 3 again and disconnects.This pendulum model hydraulic control switch has explosion-proof performance preferably.
