Description
Technical field
The present invention relates to agricultural irrigation apparatus field, be specifically related to a kind of capillary pressure regulator.
Background technology
Uniformity of irrigation water appilcation is the important indicator evaluating drip irrigation system performance, but, owing to pipeline system of distance stem is far and near
The reasons such as the different fluctuatings with landform, the inlet pressure causing different arm import and different hollow billet imports changes greatly, from
And cause field water dropper water flow uneven, affect the uniformity of irrigation water appilcation of drip irrigation system.In order to effectively control drip irrigation system
Uniformity of irrigation water appilcation, prior art is pressure regulation and Flow-rate adjustment.
CN 201310017540.6 discloses the capillary pressure regulator that a kind of pressure regulating performance is stable, it is characterised in that: it
Including upstream shell, downstream shell, baffle, lift, T type regulation component and pressure spring；Upstream shell includes successively one
The first cylindrical section, circular cone diffuser and the second cylindrical section that body is arranged；Downstream shell include the 3rd cylindrical section that is wholely set and
4th cylindrical section, the 3rd cylindrical section connects the second cylindrical section；3rd cylindrical section be provided at circumferentially spaced some gas ports；Water conservancy diversion
Body includes the first round and cylindrical structure；The middle part of the first round is provided with leads to cylindrical structure, but do not penetrate through
Centre bore；The inlet opening being provided at circumferentially spaced some connection centre bores of cylindrical structure；First round is arranged on second
In cylindrical section, cylindrical structure stretches in circular cone diffuser；Lift and be arranged in the second cylindrical section, be provided with in the middle of it one with lead
The circular port that the center-hole diameter of fluid is identical；T type regulation component includes the second round and cylinder, and cylinder is through flat
Circular port in torr and the centre bore on the first round；Pressure spring is enclosed within the cylinder of T-shaped regulation component.
Its operation principle is as follows: during work, and current enter upstream from the first cylindrical section end water inlet of upstream shell
After shell, arrive in having the cavity that upstream shell and baffle are formed, by the some inlet openings on the cylindrical structure of baffle
Enter in the cylinder of T-shaped regulation component.Current after the second round of T-shaped regulation component, the of shell downstream
Four cylindrical sections flow out.When inlet pressure increases, outlet pressure increases the most therewith, when outlet pressure increases to so that type pressure regulation group
The pressure suffered by second round of part equal to the prestressing force of pressure spring and T-shaped regulation component admission section pressure it
And time, T-shaped regulation component reaches a kind of poised state；When outlet pressure continues to increase, outside T-shaped regulation component starts upstream
Shell side stretches in the cylindrical structure of baffle to motion, the cylinder end of T-shaped regulation component, reduces cylindrical structure.
In the program, by under have the pressure change of the current in shell body to cause pressure spring to deform upon, and
By pressure spring initial regulation component, hydraulic pressure is adjusted.Owing to current are directly flowed out by downstream shell body, thus also
Pressure spring is not played directly effect, only between the water yield in the inflow in the shell body of upstream and downstream shell body
When the flowing water speed difference that formed is bigger, just can cause T-shaped regulation component generation effect.This technical scheme adjustable flow scope one
As more than 5m3/ h, is not therefore suitable for the hollow billet level flow of agricultural irrigation systems (less than 1.5m3/ h).Furthermore, China is at present also
Rarely found capillary pressure regulator.Summary considers, develops the hollow billet inlet pressure that a kind of pressure regulation power is low, suit large area to popularize
Actuator is significant.
Summary of the invention
It is an object of the invention to provide a kind of the low capillary pressure regulator of pressure regulation power.
For reaching above-mentioned purpose, the base case of the present invention is: capillary pressure regulator, including upstream shell, downstream outside
Shell and regulation component, upstream shell is hollow barrel, and the lower end outer wall of upstream shell is provided with external screw thread, downstream shell in
Hollow barrel, the left end outer wall of downstream shell is provided with external screw thread, and regulation component includes housing, baffle plate and ball, housing
Being formed with the cavity of hollow, the top of housing is provided with the screwed hole being connected with upstream outer casing screw, the side of housing be provided with under
The screwed hole that trip outer casing screw connects, the cavity connection of upstream shell, downstream shell and housing, it is interior and alive that baffle plate is placed in cavity
Dynamic it is hinged on housing, in ball is placed in cavity and be positioned at the lower section of baffle plate.
Operation principle and the advantage of this programme are: upstream shell connects with water inlet pipe, and downstream shell connects with outlet pipe.
Water enters into inside the cavity of housing through upstream shell body, when the intake pressure of upstream shell raises, due to ball
Deformation effect promotes baffle plate to be blocked by upstream shell, thus limits the water yield of downstream shell；Intake pressure when upstream shell
During reduction, the water yield of downstream shell still keeps setting value in advance.
Compared to existing technology, the baffle plate in the program is owing to directly being impacted by the water inlet in the shell of upstream, so sensitive
Spending higher, hydraulic pressure increases baffle plate will press to ball at once, and ball will upwards jack-up be kept off at once when hydraulic pressure is less
Plate.Even more important a bit: the spring used in existing scheme can produce oxidation reaction owing to being chronically in water, middle institute
The elastic force of known oxidation reaction meeting spring has large effect, the life-span of spring of not only decaying, and can make the bullet of spring
Property effect is insensitive.But this programme just overcomes this problem, ball is used to compare spring relatively reliable.This pressure regulator
Owing to being quick on the draw, so it is relatively low to play pressure regulation power, not only meets agricultural irrigation, and it is extensive as elastic force to have employed ball
Copy is the most reliable.
Preferred version one: based on the preferred version of scheme, the upper end outer wall of upstream shell is provided with a circle agnail, under
The right-hand member of trip shell is provided with a circle agnail.Agnail is used for fixing preventing water pipe antipriming pipe and comes off from the shell of upstream so that connect more
For reliably.
Preferred version two: the preferably preferred version of, the lower end of housing is provided with for opening that ball is passed through
Mouth is also additionally provided with end cap with cavity to the opening connected, the lower end of housing, and end cap is threadeded with housing and seals up opening.
The purpose arranging opening and end cap is to facilitate ball to put in housing.When needing to regulate preset pressure value, can be by more
Change ball to realize.
Preferred version three: the preferably preferred version of two: ball is made up of natural gum.Natural gum not only quality
Softer and resilience good, the intake pressure of upstream shell can there be is the most sensitive reaction.
Preferred version four: the preferably preferred version of three: upstream shell and housing, downstream shell and housing and end cap
And all it is respectively equipped with sealing ring between housing.Because the mode sealed has multiple, and it is not only simple but also economical to arrange sealing ring
Material benefit, because sealing member is easy to get and effect is preferable.
Preferred version five: the preferably preferred version of four: baffle plate uses rigid plastic sheet.Rigid plastic sheet can be long-term
Be in water and oxidation reaction will not be produced, it is possible to use the most permanent.
