Description
Technical field
The present invention relates to a kind of field irrigation facility, more particularly to a kind of field underground formula hydrant and field underground formula to give
The application method of water bolt.
Background technology
At present, the hydrant of field irrigation facility brings many facilities to field irrigation, very easily carries out farmland irrigating
Irrigate.But the hydrant in farmland be an exposure to mostly ground off-balancesheet, to winter, mercury dropped, freeze, can damage farmland to
Water bolt, thus easily cause the loss of unnecessary field irrigation.Although some places are given using insulation material parcel farmland
Water bolt, certain effect is served, the material of consuming is a no small spending, if farmland hydrant wraps up not tight, together
Sample can damage farmland hydrant.
The content of the invention
It is a primary object of the present invention to solve the problems, such as that above-mentioned winter season field hydrant is present, there is provided a kind of field underground
The application method of formula hydrant and field underground formula hydrant.
The technical solution adopted for the present invention to solve the technical problems is：
Hydrant well is placed equidistant by design requirement along agriculture water supply pipe in field irrigation region, hydrant well uses coagulating cement
Native material or glass steel material make, and install field underground formula hydrant in hydrant well, field underground formula hydrant is by fixing
Sleeve, moving casing, fixes sleeve sealing gasket, moving casing sealing gasket, sealing piston, screw rod, outlet pipe, locking device and method
Orchid is tried to get to the heart of a matter seat composition, and the bottom of field underground formula hydrant is fixes sleeve, and fixes sleeve be in integrally barreled, fixes sleeve use
Metal material or glass steel material make, and ring flange base is installed in the bottom of fixes sleeve, and ring flange base uses metal material
Making, ring flange base is connected with the diversion pipe flange on feed pipe, and fixes sleeve is connected by aqueduct with feed pipe, Gu
The top for determining sleeve sets interior exhibition bead along port inner wall, and fixes sleeve sealing is installed in the inner side of interior exhibition bead along interior exhibition bead
Pad, fixes sleeve sealing gasket are made using quality of rubber materials or plastic material or polyurethane material, equidistant on the inwall of fixes sleeve
Guide rail is set, and at least 4 guide rails, boot activity sleeve pipe moves up and down, and fixes sleeve upper outside installs locking device, locking
Device is made using category material, and moving casing, which is retracted in fixes sleeve, uses locking device locking moving casing.
Moving casing is in integrally barreled, and the bottom of moving casing is inserted in fixes sleeve, moving casing and fixes sleeve
Match, moving casing is made using metal material or glass steel material, and the bottom port of moving casing is set along port outer wall
Abduction bead is put, moving casing sealing gasket is installed along on the outside of abduction bead, moving casing sealing gasket uses quality of rubber materials or modeling
Expect that material or polyurethane material make, moving casing top sets outlet pipe, and water source is outwards conveyed by the delivery port of outlet pipe,
Screw rod is installed at the top of moving casing, screw rod penetrates moving casing from top, and the upper end of screw rod installs handwheel, penetrates movable sleeve
Sealing piston is installed in the bottom of screw rod in pipe, rotates handwheel, and handwheel drives screw rod to rotate, and stops as the rotation of screw rod drives
The keying control water yield of water piston closes water outlet, and sealing piston, screw rod and handwheel are made using metal material, moving casing
In bottom insertion fixes sleeve, guiding groove is set, guiding groove insertion fixes sleeve is led in the abduction bead of moving casing bottom
Rail, guiding groove match with the guide rail of fixes sleeve, and the bottom of moving casing moves up and down in fixes sleeve, moving casing
Abduction bead rises to the top of fixes sleeve, and the abduction bead of moving casing is in contact with the interior exhibition bead of fixes sleeve, interior
The fixes sleeve sealing gasket of exhibition bead matches to form closed circle with the moving casing sealing gasket of abduction bead.
The application method of field underground formula hydrant, equidistantly set along agriculture water supply pipe in field irrigation region by design requirement
Hydrant well to be put, field underground formula hydrant is installed in hydrant well, the bottom of field underground formula hydrant is fixes sleeve, Gu
Ring flange base is installed in the bottom for determining sleeve, and ring flange base is connected with the diversion pipe flange on feed pipe, and fixes sleeve passes through
Aqueduct is connected with feed pipe.
When field irrigation to be carried out, the well lid of hydrant well is opened, the lower end of moving casing is in being inserted in fixed cover
In cylinder, the locking device of locking moving casing is opened, rotary moveable sleeve pipe, the direction of outlet pipe is adjusted, is pulled out along fixes sleeve
Moving casing, moving casing move up along the guide rail on the inwall of fixes sleeve, and the bottom of moving casing moves up, activity
The abduction bead of sleeve pipe rises to the top of fixes sleeve, and the abduction bead of moving casing connects with the interior exhibition bead of fixes sleeve
Touch, the fixes sleeve sealing gasket of interior exhibition bead matches to form closed circle, movable sleeve with the moving casing sealing gasket of abduction bead
The outlet pipe of pipe stretches out the well head of hydrant well, the farmland to be irrigated of outlet pipe alignment of moving casing, opens on moving casing
Water check valve, the water source in feed pipe flows out by the delivery port of outlet pipe, pours into the farmland to be irrigated.
When terminating field irrigation, water check valve is closed, moving casing is pressed downwards, moving casing is inserted fixes sleeve
Interior, the guiding groove of moving casing moves down along the guide rail of fixes sleeve, and the bottom of moving casing is in fixes sleeve to moving down
Dynamic, the abduction bead of moving casing separates with the interior exhibition bead of fixes sleeve, guiding groove the leading along fixes sleeve of moving casing
Rail moves down, until in the fully-inserted fixes sleeve in bottom of moving casing, closes locking device, locking moving casing, lid
The well lid of upper hydrant well.
The present invention is the application method of field underground formula hydrant and field underground formula hydrant.It is rational in infrastructure, design department
Learn, it is easy to use, prevent jelly from ruining, simple for production, cost is low, easily promotes, and original hydrant is the overall ground for being erected at farmland
On table, although exposed farmland hydrant is easy to use, the operation of other farm implements is influenceed, field underground formula hydrant can be put
Putting does not influence the use of other farm implements under earth's surface.When the present invention irrigates, supplied water first by water pump for main-supply, be transported to farmland
Field, then discharged by each hydrant, reach the purpose of irrigation.
