Description
Technical field
The utility model relates to water-saving irrigation instrument technical fields in agricultural production, and in particular in a kind of pressure-compensated
Flat water dropper is inlayed in labyrinth flow-path.
Background technique
Currently, mostly using patch type drip irrigation pipe to be irrigated greatly in micro drip-irrigation engineering.Used water dropper is traditional flat
One end of flat water dropper, the rectangular plate body that this flat water dropper is integral, rectangular plate body is equipped with inlet opening, and the other end is equipped with
Square groove corresponding with drip irrigation pipe apopore, the outer surface of rectangular plate body be equipped with labyrinth flow-path, labyrinth flow-path into
The mouth of a river is connect with inlet opening, and the water outlet of labyrinth flow-path is connected to square groove.
It is fixed in use, the rectangular slab external surface with labyrinth flow-path is adjacent to trickle irrigation inside pipe wall pressure welding, opposite
Get water hole on the trickle irrigation tube wall of square groove position, in this way, in drip irrigation pipe pipe flowing water by inlet opening flow into labyrinth flow-path,
It is flowed out using square groove from trickle irrigation tube wall apopore.
The deficiency of this flat water dropper is: since the labyrinth flow-path of water dropper is adjacent to trickle irrigation inside pipe wall, with drip irrigation pipe pressure
When weldering, since the wall thickness of drip irrigation pipe is different, the thickness for going deep into labyrinth flow-path is just different, and then influences the water flow out of flat water dropper
Amount；Meanwhile when the pressure of water generates variation, the water flow of flat water dropper also will affect.Traditional interior edge flat water dropper paving
If length, the wall thickness range of product are subjected to limitation, can only make under conditions of flat plot drop is not more than 0.5 meter
With.

Regulator hole and the second regulator hole for being connected to pressure-compensating chamber.
Surge-chamber realizes that nature seals by the sealing fixation of cover board and bottom plate, passes through the first pressure regulation opened up on bottom plate
Hole and the second regulator hole can realize the connection of labyrinth flow-path and pressure-compensating chamber, realize its compensation function.
Further, the water chamber being connected to apopore is offered in the supporting table, supporting table surface offers company
Pick out the effluent trough of water cavity and pressure-compensating chamber.
Water flow through labyrinth flow-path energy dissipating from regulator hole enter in pressure compensation room with the iris action in pressure compensation room,
It is imported in water chamber after further energy dissipating by effluent trough and is discharged into the catch basin being connected to drip irrigation pipe from apopore, for dripping
It fills.
Further, the labyrinth flow-path is located at the side of reservoir chamber and arranges along three side edge of bottom plate, sets on bottom plate
Be equipped with ┓ type seal line, the seal groove of cooperation lid relative position setting formed for guide water flow from labyrinth flow-path water inlet end to
The waterwall of water outlet.
Waterwall, which is arranged, can make water inlet end the going out to labyrinth flow-path that labyrinth flow-path is flowed through by the water for crossing water chamber outflow
Water end (W.E.) guarantees that it completely passes through labyrinth flow-path and reaches maximum effect of energy dissipation.
Preferably, the cover board is equipped with filtering window in water inlet.
Filtering window prevents from causing water dropper to block into water dropper for being filtered the impurity in drip irrigation pipe.
The utility model has the beneficial effects that
One, since labyrinth flow-path designs on the inner wall of the housing, while compensating plate is increased, so can be avoided drip irrigation pipe pipe
Wall gos deep into labyrinth flow-path and influences flow.
Two, it can be avoided trickle irrigation tube wall to go deep into labyrinth flow-path and influence flow, and in the case where variation in water pressure, energy
Enough keep flow constant.
