In figure：1- water outlet end housings；2- voltage stabilizing O-ring seals；3- valve core caps；4- barrier films；5- valve core tubes；6- springs；7-
Pad；8- water inlet end housings；9-O type sealing rings；10- water inlet gaily decorated basket plugs；11- housings.
Embodiment
As shown in figure 1, a kind of pressure flow regulator for low pressure irrigation, the adjuster includes the He of water outlet end housing 1
Water inlet end housing 8 link together composition housing 11, be placed in into the valve core tube 5 in water end housing 8 and be placed in water outlet end housing 1
Interior valve core cap 3.Valve core cap 3, the composition adjusting pressuring valve core of valve core tube 5.
One end of valve core tube 5 is provided with water inlet gaily decorated basket plug 10, and its other end is connected with valve core cap 3, is set on the valve core cap 3
There is water outlet side groove.Adjusting pressuring valve core can be moved axially under the driving of difference force, by changing itself and water inlet gaily decorated basket plug
The distance between 10, so that water inlet flow section area is decreased or increased, the different loss of flood peakes are caused, outlet pressure is kept
It is constant.
Current limliting groove is provided with water outlet side groove, and is inlaid with voltage stabilizing O-ring seal 2.Voltage stabilizing O-ring seal 2 and current limliting groove
And water outlet end housing 1 forms a flow restriction, pressure regulator delivery port current can only pass through voltage stabilizing O-ring seal 2 and limit
The narrow and small path of chute formation is flowed into and out, and forms hydraulic damping effect, and protection adjusting pressuring valve core and steady pressure adjuster are gone out
Mouth pressure plays an important role.
Spring 6 is socketed with valve core tube 5；Spring 6 is initially in compressive state, to balance under preset pressure during main function
The difference force acted on the side section of adjusting spool two.
Intake and barrier film 4 is provided between end housing 8 and water outlet end housing 1.
Wherein：Water inlet end housing 8 is connected through a screw thread with water outlet end housing 1.
Pad 7, O-ring seal 9 are sequentially provided between valve core tube 5 and water inlet gaily decorated basket plug 10.Water inlet gaily decorated basket plug
10 play a part of damming and compress O-ring seal 9, for replacement o sealing ring 9, water inlet gaily decorated basket plug 10 and water inlet end
Shell 8 is using threaded connection.O-ring seal 9 mainly seals, in order to prevent long-time friction damage, general using mark
Quasi- part, is conveniently replaceable.
Barrier film 4 is that silicon rubber presss from both sides fabric ripple ring film, and its inner side is nested on valve core tube 5, and its outside is by machinery
Force and be embedded in between water end housing 8 and water outlet end housing 1.Barrier film 4 is acted on of both primarily serving：1. sealing function, is protected
Card water inlet end housing 8 and the sealing of the junction of water outlet end housing 1, while it and water inlet end housing 8, water outlet end housing 1, pressure regulator valve
Core and O-ring seal 9 are collectively forming a cavity, and cavity is communicated by being opened in into the stomata on water end housing 8 with air.②
The effect of involving is played in axial movement to adjusting pressuring valve core.
End housing 8 of intaking is provided with stomata, and the stomata is mainly to ensure that spring 6 is installed when adjusting pressuring valve core is axially moved
Chamber and ambient pressure it is consistent, when adjusting pressuring valve core is moved to water inlet end, the installation cavity inner volume of spring 6 reduces, additional air from
Stomata is discharged, conversely, when adjusting pressuring valve core is moved to delivery port side, spring 6 installs cavity volume increase, outside air passes through stomata
Into.
Water outlet end housing 1 is provided with positive stop lug boss, and position-limiting action is played in axial movement of the positive stop lug boss to adjusting pressuring valve core.
During work, water is from water inlet end housing 8, by the cross-section of river between water inlet gaily decorated basket plug 10 and adjusting pressuring valve core, forms main
The loss of flood peak after, flow into adjusting pressuring valve core, subsequently into downstream line.Initially, in the presence of the pretightning force of spring 6, pressure regulator valve
Core remains static, and outlet pressure increases with the increase of inlet pressure.When inlet pressure continues to increase, outlet pressure reaches
During to certain value, due to the difference of adjusting pressuring valve core two ends lifting surface area, act on adjusting pressuring valve core Outlet Section and rubber diaphragm 4
Water pressure compression spring 6, promote adjusting pressuring valve core to import direction move.Make between adjusting pressuring valve core and water inlet gaily decorated basket plug 10
Spacing reduce, the loss of flood peak increase so that outlet pressure reduce again so that outlet pressure maintenance stably.Work as inlet pressure
During reduction, process is on the contrary.
