Abstract
The utility model relates to a mechanical current switch for gas water heaters, which comprises a body 1 and is characterized in that the body 1 is externally fixed with a microswitch 2, and a bob 3 is arranged in the lower portion in the body 1. The lateral edge of the body 1 is connected with a pedestal 4, wherein a rotation shaft 6 supported by a supporting bolt 5 is arranged, and a lever 8 connected by a driving disc 7 and the rotation shaft 6 is arranged. The other end of the lever 8 is extended into the body 1 and is arranged above the bob 3, the rotation shaft 6 projecting from the pedestal 4 is also provided with a restoring spring 9and the driving disc 7 which is connected with a clamp plate 10, and the other end of the clamp plate 10 is adjacent to the microswitch 2. The utility model has simple structure, small cubage, and reliable performance.
Description
The utility model relates to a kind of flow control apparatus for water, particularly a kind of mechanical type water flow switch that is used for gas heater.
Now, the flow control apparatus for water that gas heater on the market uses is water valve and aqueous vapor interstage valve, it is that the skin drum passes to the aqueous vapor interstage valve after sensing hydraulic pressure by the pressure of skin drum induction water, and the aqueous vapor interstage valve backs down contactor again and backs down gas circuit simultaneously and carry out current control.This flow control apparatus for water, complex structure, volume is bigger, manufacturing process and required precision height, the minimum hydraulic pressure of starting is 0.025Mpa, limited by regional hydraulic pressure, and there have consumable accessory skin drum to be contained in to be middle, have the hidden danger of leaking, and cost is higher.
It is a kind of simple in structure that the purpose of this utility model is to provide, the mechanical type water flow switch that cost is low.
The utility model is achieved in that a kind of mechanical type water flow switch, and it comprises body, it is characterized in that: described body external fixation has sensitive switch; The below is provided with float in the described body; Described body side is connected with bearing, and the rotating shaft through the supporting screw supporting is arranged in the bearing, and the lever that is connected with rotating shaft through drive plate is arranged, and the other end of lever stretches in the described body, and is positioned at the float top; Stretch out in the outer rotating shaft of bearing and also be provided with return spring, drive plate, be connected with pressing plate on this drive plate, the other end and the sensitive switch of pressing plate are adjacent.
The lower end of the utility model body is connected with the water source, and the upper end of body is connected with the water tank of gas heater, and sensitive switch is connected with the control circuit of gas heater, when current pass through the utility model, after float is sensed current, push lever, because lever moves, drive rotating shaft and rotate, at this moment pressing plate is opened, sensitive switch is moving closed simultaneously, the pulse of gas heater begins discharge, and gas circuit is opened in the electromagnetically operated valve adhesive, finish the process of combustion ignition, enter operating state; After water is turned off, the float return, return spring work, the pressing plate return turn-offs sensitive switch, and sensitive switch turn-offs electromagnetically operated valve again, and electromagnetically operated valve cuts out gas circuit again, the power cut-off state.
The utility model is simple in structure, and volume is little, dependable performance, and its starting hydraulic pressure is 0.015Mpa, and the utility model do not have consumable accessory design, cost is low.
The utility model is described in further detail below in conjunction with drawings and Examples:
The structural representation of Fig. 1, the utility model embodiment;
Fig. 2, be the A-A cutaway view of Fig. 1.
Referring to above-mentioned accompanying drawing as can be known: a kind of mechanical type water flow switch, it comprises body 1, it is characterized in that: described body 1 external fixation has sensitive switch 2; The below is provided with float 3 in the described body 1; Described body 1 side is connected with bearing 4, and the rotating shaft 6 through supporting screw 5 supportings is arranged in the bearing 4, and the lever 8 that is connected with rotating shaft 6 through drive plate 7 is arranged, and the other end of lever 8 stretches in the described body 1, and is positioned at float 3 tops; Stretch out in the outer rotating shaft 6 of bearing 4 and also be provided with return spring 9, drive plate 7, be connected with pressing plate 10 on this drive plate 7, the other end of pressing plate 10 is adjacent with sensitive switch 2.
