Abstract
Disclosed is a hydraulic power switching valve. According to the hydraulic power switching valve, the force intensity of a spring is adjusted through an adjustment device, and the opening force or the closing force of a valve clack is adjusted; when the pressure of a water source with pressure is larger than that of the spring controlling opening of the valve clack, the water source with pressure can flow into a valve cavity through the valve clack, water in the valve cavity is the water source with pressure at the moment and water in a normal-pressure water inlet is a water source without pressure, and a flap is pushed by the water source with pressure to be closed at the moment; when the pressure of the water source with pressure is smaller than the opening force of the valve clap, the valve clack is pushed by the spring to be closed, the pressure of the water in the valve cavity disappears and the flap is opened at the moment, and the normal-pressure water source can flow into the valve cavity to achieve switching of water sources.
Description
Technical field
The present invention relates to a kind of hydraulic control valve, particularly a kind of by the valve of the different water source switchings of waterpower control.
Background technique
Hydraulic control valve in prior art is all generally by the pass of the pressure control valve of water self or closes, all generally two general formulas, current only have a kind of pressure water source by valve, water source with no pressure can not pass through valve, when system need water source with no pressure by time motor-operated control valve or change system can only be installed, cause installing space increase, labor intensity increase.
Summary of the invention
The object of the invention is to: design a kind of waterpower switching valve that different water sources can be passed through when needed.
The present invention adopts following structure to realize above-mentioned purpose, waterpower switching valve by: valve body, flap, controlling device, spring, turnover panel form, spring fitting is on flap, simultaneously controlling device is arranged on spring, and valve body is divided into 1 pressure water source water intake, 1 normal pressure water source water intake, 1 water outlet.
Adopt as above structure, adjust the intensity of force of spring by controlling device, adjust the power that flap opens or closes, when the pressure in pressure water source is greater than the power of controlling the spring opened of flap, pressure water source just can flow in valve pocket by flap, at this moment the water in valve pocket is pressure water source, normal pressure water intake is water source with no pressure, at this moment pressure water source promotion turnover panel is closed, in the time that pressure water source pressure is less than the power that flap opens, spring promotes flap and closes, at this moment in valve pocket, the pressure disappearance turnover panel of water is opened, normal pressure water source can flow into valve pocket, realize the object of water source switching with this.
Accompanying drawing explanation
Fig. 1 is enforcement phase diagram of the present invention.
Embodiment
A kind of waterpower switching valve as shown in Figure 1, comprise: valve body 1, flap 2, controlling device 3, spring 4, turnover panel 5 forms, valve body 1 is provided with water intake 6, 7 and water outlet 8, turnover panel 5 is arranged on water intake 7 places, turnover panel 5 is provided with movable axis 10, the position that turnover panel 5 is installed at water intake 7 places is provided with seal ring 12, at water intake, 6 places are provided with flow-guiding mouth 9, flap 2 is arranged on flow-guiding mouth 9 places, spring 4 is arranged on flap 2, controlling device 3 is arranged on spring 4, when use, first adjusted the tensile strength of spring 4 by controlling device 3, in the time that the pressure of the water of water intake 6 is greater than the tension force of spring 4, at this moment the thrust of water promotion flap 2 moves backward, make water enter into valve pocket 11 by flow-guiding mouth, at this moment valve pocket 11 is in there being pressure condition, promote turnover panel 5 by the pressure of water and close water intake 7, turnover panel 5 seals by seal ring 12, water is flowed out by water outlet 8.When the pressure of water intake 6 is less than the tension force of spring 4, at this moment spring 4 promotes flap 2 and moves and close flow-guiding mouth 9 forward, and at this moment the waterpower of valve pocket 11 disappears, and turnover panel 5 is opened automatically, and the water source of water intake 7 can flow to water outlet 8 by valve body 11 like this.Realize the waterpower switching valve that can pass through when needed at different water sources with this, reduce the object of installing space and labor intensity simultaneously.In figure, the direction of arrow is water (flow) direction.
Claims (3)
1. a waterpower switching valve, it is characterized in that waterpower switching valve by: valve body, flap, controlling device, spring, turnover panel form, spring fitting is on flap, simultaneously controlling device is arranged on spring, and valve body is divided into 1 pressure water source water intake, 1 normal pressure water source water intake, 1 water outlet.
2. a kind of waterpower switching valve according to claim 1, is characterized in that: turnover panel is provided with movable axis.
3. a kind of waterpower switching valve according to claim 1, is characterized in that: be provided with seal ring in the position that turnover panel is installed.
