Background technology
Air inlet and exhaust valve is one of important safety guard of field pipeline irrigation engineering, general to install with pipe-line system only
Can along the stem of slope pipeline section, or adverse grade pipeline section afterbody, pipeline section prominence and pipeline are towards the change rolled under water (flow) direction more than 10 °
It is quite varied in irrigation system application at slope.Its effect is the air irrigated in initial discharge line, is prevented because exhaust is not smooth,
Influence pipeline crosses water, or even forms water hammer or superpressure booster；Air enters pipeline during shutdown, prevents from forming vacuum because of back of pipeline stream
Destruction of the negative pressure to pipeline.
Current engineering air inlet and exhaust valve device in practice, is typically mounted at the top of system pipeline, and need to build masonry by laying bricks or stones
Structure inspection well is protected, and this air inlet and exhaust valve and mounting means have the following aspects：
1st, valve well influences the problem of field farm machinery tillage, often occurs being broken by agricultural machinery, or break the situation of agricultural machinery；
2nd, the air inlet and exhaust valve of cast iron or steel material corrosion damaged condition in underground inspection shaft is serious；
3rd, inspection shaft is time-consuming in field construction, takes farmland, and cost is higher；
Due to the presence of problem above, the Function and using effect of air inlet and exhaust valve are had a strong impact on, or even cause pipe
It is interior to produce water hammer or explosion, and then influence the normal operation of pipe-line system；Because inspection shaft influences farming to cause, engineering is discarded to be showed
As also relatively universal, extreme loss and waste are caused to national water-saving engineering project.
The content of the invention
The purpose of this utility model is to provide a kind of direct burial air inlet and exhaust valve, to solve the above problems.
In order to achieve the above objects and other related objects, the utility model provides a kind of direct burial air inlet and exhaust valve, including：
Valve body, body top is protective cover, and with upper valve body to be threadedly coupled, protective cover inwall side is intake and exhaust to protective cover
Hole, the outside of port is dust cover.
Preferably, the valve body middle part is upper valve body, and upper valve body top is port, and lower outside is spiral shell with lower valve body
Line is connected, and with support also to be threadedly coupled, carriage center position is guide cylinder to lower inside, and support is integrated knot with guide cylinder
Structure.
Preferably, the lower valve body top is to be threadedly coupled with upper valve body, and centre is provided with watertight rubber, and bottom is connection method
Blue disk.
Preferably, there is guide post in the support guide cylinder of the upper valve body cavity inner bottom part, guide post top is helicitic texture,
Upper sealing pressing plate and watertight rubber are fixed by nut in top, and guide post and lower sealing pressing plate are structure as a whole.It is with guide cylinder
Track floats and closes under the buoyancy of water, falls back on support under gravity.
It is using good effect of the present utility model：
1st, whole valve body is installed and below the arable layer of ground, thoroughly solves traditional air inlet and exhaust valve inspection shaft influence agricultural machinery
The problem of farming.
2nd, package unit be all-plastic structure, will not corrosion, do not block.
3rd, package unit simple structure, function-stable, it is not necessary to check well protection, can be greatly reduced construction investment, while
Solve the problems, such as that traditional inspection shaft field construction takes farmland.

Specific embodiment
As shown in the figure：
A kind of air inlet and exhaust valve, including：
Valve body, including upper valve body 3 and lower valve body 6, body top are protective cover 1, and protective cover 1 is with upper valve body 3 for screw thread connects
Connect, the inwall side of protective cover 1 is port 2, and the outside of port 2 is dust cover.
In the embodiment of the utility model one, the valve body middle part is upper valve body 3, and the top of upper valve body 3 is port 2, under
With lower valve body 6 to be threadedly coupled, with support 5 also to be threadedly coupled, the center of support 5 is guide cylinder 8 to lower inside in portion outside,
Support is structure as a whole with guide cylinder.
In the embodiment of the utility model one, with upper valve body to be threadedly coupled, centre is provided with sealing rubber on the lower valve body top
Glue 7, bottom is ring flange 10.
In having guide post 9 in the embodiment of the utility model one, the support guide cylinder 8 of the upper valve body cavity inner bottom part, it is oriented to
The top of bar 9 is helicitic texture, and upper sealing pressing plate 13 and watertight rubber 7 are fixed by nut 14 in top, guide post and lower sealing pressure
Plate is structure as a whole.Closed as track floats under the buoyancy of water with guide cylinder, support is fallen back under gravity
On.
Upper and lower sealing pressing plate, watertight rubber, guide post and nut constitute sealing valve plate 4.
Direct burial air inlet and exhaust valve is provided with two ways, and the first mounting means is that air inlet and exhaust valve is installed on into pipeline top
Portion, below field level arable layer, around fills stone fragment filter layer, and to increase intake and exhaust effect, top arable layer is directly used
Earthen backfill.
Second mounting means is to be satisfied with field production roadside and the intersection of field ridge, concrete protection of pipe is used, in concrete pipe
Stone fragment filter layer is filled, is connected with elbow and connecting tube between air inlet and exhaust valve and underground piping.
Operation principle and working are described：
1st, it is vented：Irrigate initial, during pipeline water-filling, gas in pipelines is discharged from port to another port,
And the bottom by protective cover enters stone fragment filter layer soil body diffusion, is discharged inner air tube using the permeability of the soil body
Ground；Sealing valve plate by water buoyancy rise, internal water pressure effect under close port, make port seal and it is not permeable
Leakage, exhaust process is finished.
2nd, air inlet：Irrigation terminates, and when pipeline stops supplying water, water backflow in pipe, sealing valve plate is made in Gravitative Loads and siphon
Fallen with lower, port and open, by farming layer soil body, stone fragment filter layer, port enters another to air
Port enters pipeline, destroys pipeline vacuum negative pressure, so as to be protected to pipeline.
