Description
Technical field
The present invention relates to a kind of pressure regulator, particularly a kind of case type low pressure high volume pressure regulator that is applicable to low-pressure drip irrigation system belongs to the agricultural water-saving irrigation technical field.
Background technology
Pressure regulator is the important component part of drip irrigation system, its major function is the time to make pressure regulator downstream hydraulic pressure keep invariable or respectively pour water apart from the downstream when the irrigation system stem and guarantee that each porch, sub-district water pressure is equal, makes drip irrigation system keep satisfactory uniformity of irrigation water appilcation when the sub-district distance does not wait when the pressure regulator upper water is pressed with fluctuation.
For traditional drip irrigation system, at present supporting with it pressure regulator kind is more, and main pressure regulator structure is a structure shown in the accompanying drawing 7 both at home and abroad, the domestic pressure regulator that has a kind of at the low pressure and mass flow characteristics in addition, and its structure is as shown in Figure 6.
The pressure regulation mechanism of the pressure regulator shown in the accompanying drawing 7 is: when the pressure regulator upstream has certain water pressure, current are through import gaily decorated basket plug outer, by T type pressure regulation assembly cavity flow downstream, continuous increase along with upstream pressure, downstream pressure also improves thereupon, because the effect of spring force, before upstream pressure reached certain certain value, pressure regulation assembly downstream kept " holding out against " state with outlet always.Downstream pressure on acting on the pressure regulation assembly during greater than initial elastic force of spring and upstream pressure sum pressure regulator begin operate as normal, effect lower spring at total pressure head is compressed, the pressure regulation assembly upstream moves, the area of the import this moment cross-section of river reduces, the loss of flood peak increases, and outlet pressure reduces.Opposite when upstream pressure reduces, to reply at the effect lower spring of total pressure head, the pressure regulation assembly moves downstream, and the area of flow surface increases, and the loss of flood peak reduces, and outlet pressure increases, and keeps outlet pressure stable according to this.
The critical component of pressure regulator shown in the accompanying drawing 6 is automatic flow regulating valve, it is made up of ball float, ball valve and the valve rod that connects the two, it is controlled the unlatching of water intaking valve automatically according to fluctuation in stage in the case or closes, and realizes the adjusting of flow, guarantees to keep within the specific limits in whole drip irrigation process middle water level.Flow regulating valve has used lever principle, and when water level rose arrival control water level, ball float floated, and ball float drives valve rod and rises, and valve opening reduces, and inflow reduces, water level depression in the water tank; When water level depression broke away from the control water level, ball float and valve rod were sagging, and valve opening increases, and inflow increases, and water level rises in the case.The interior water level of guard box is no more than the excursion of regulation in this way.As " relay-type " turn of tidal stream device, with table in the case dynamic water can be transformed into Static Water with water tank of voltage regulation, application is decided stable level and is gone out stream, and promptly current flow into pipe network again through the water tank voltage stabilizing earlier, realize the pressure regulation function.
A pressure regulator outlet pressure and a pressure regulation power present and that traditional drip irrigation system is supporting are all higher, are not suitable for low-pressure drip irrigation system.The low pressure adjuster supporting with low-pressure drip irrigation system mostly is imported product, version such as accompanying drawing 7, and its complex structure and price are higher.The used pressure regulating valve price of case type low pressure high volume pressure regulator shown in the accompanying drawing 6 is higher, and volume is bigger.So still there is not economical and practical case type low pressure high volume pressure regulator at present.
