Description
Technical field
The utility model belongs to agricultural irrigation technology more particularly to a kind of agricultural irrigation pipeline rapid escape valve.
Background technique
The pipeline of the systems such as some plumbing, irrigation or water process is closed pipeline, some local meetings in pipeline trip
Because pipeline shape and the difference of height of water level cause some pipe section points in drainage procedure to gather a small amount of or large quantity of air, seriously
Will form vacuum, thus the case where causing pipeline impeded drainage.It is solved the above problems in the prior art using exhaust valve, but
That exhaust valve sealing performance in the prior art is bad, will lead to after exhaust the liquid in pipeline from exhaust valve at let out
Dew；In addition, when the air pressure in pipeline is excessively high, often lead to spool rise it is too fast before gas in pipelines does not drain also just
Being blocked gas vent cannot continue to be vented.Therefore, it is necessary to be improved to exhaust valve in the prior art to solve above-mentioned technology
Problem.
Utility model content
The utility model in view of the above shortcomings of the prior art, has invented a kind of simple production process, long service life, close
The good agricultural irrigation pipeline rapid escape valve of envelope property.
To achieve the goals above, the utility model adopts the following technical solutions:
A kind of agricultural irrigation pipeline rapid escape valve, including valve body and floating ball are provided with valve chamber, water inlet in the valve body
Mouth and gas vent, the floating ball are placed in valve chamber；It further include that hydraulic pressure slows down plug, annular magnet, sealing strip and rubber, it is described
Hydraulic pressure slow down plug and be mounted in water inlet, the annular magnet is mounted on gas vent, and annular magnet is enclosed with sealing strip；
The floating ball is magnetic floating ball, and the surface of floating ball is provided with one layer of rubber.
The innovative point of the utility model is that hydraulic pressure is equipped on the water inlet for valve body slows down plug, slows down plug by hydraulic pressure
Slow down the flow velocity and pressure of water in valve body, it is ensured that floating ball can slowly float the intracorporal air of valve is drained；And use ring
Attraction force between shape magnet and floating ball increases the leakproofness of sealing strip and rubber, and water is avoided to reveal from gas vent.
Further, the upper and lower ends that the hydraulic pressure slows down plug are provided with grid, and hydraulic pressure slows down the inside of plug filled with steel
Pearl or rubble reduce the flow velocity and hydraulic pressure of liquid in exhaust valve by the blocking of steel ball and rubble, ensure that floating ball being capable of rule
Float in valve chamber and ensure the leakproofness at gas vent.
Further, the magnetic attracting force between the annular magnet and floating ball is the 4/5 of the gravity of floating ball, in attraction
Under the action of the buoyancy of water, the rubber on floating ball surface layer can be closely in conjunction with sealing strip, it is ensured that leakproofness；When water in valve chamber
The attraction effect that floating ball can be detached from toroidal magnet after the decline of position slowly moves down.
Further, the sealing strip is elastic sealing strip, between enhancing and rubber.
Utility model has the advantages that quickly adequately the air in pipeline can be discharged for the utility model, use
Buoyancy and magnetic force are sealed design to gas vent, ensure that the intracorporal leakproofness of valve；And the intracorporal hydraulic pressure of valve and flow velocity are (main
If the speed that water level rises) it is all relatively low, valve intracorporal air can be all drained during floating ball rises, can be with
Guarantee air when through the connector of piping and exhaust valve, air can be entered quickly in exhaust valve；And it is integrally tied
Structure is simple, manufacturing technique requirent is low, production cost is low, is able to carry out large-scale popularization and application.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of agricultural irrigation pipeline rapid escape valve of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing:
In the description of the present invention, it should be noted that the orientation or positional relationship of the instructions such as "inner", "outside" is base
In orientation or positional relationship shown in the drawings or the utility model product using when the orientation usually put or position close
System, is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning are necessary
With specific orientation and specific orientation construction and operation, therefore should not be understood as limiting the present invention.
As shown in Figure 1, a kind of agricultural irrigation pipeline rapid escape valve, including valve body 1, floating ball 2, hydraulic pressure slow down plug 6, annular
Magnet 7, sealing strip 8 and rubber 9 are provided with valve chamber 3, water inlet 4 and gas vent 5, setting under valve chamber 3 in the valve body 1
There is water inlet 4, gas vent 5 is provided on the top of valve chamber 3, the floating ball 2 is placed in valve chamber 3, and the diameter of floating ball 2 is slightly less than
The internal diameter of valve chamber 3.The hydraulic pressure slows down plug 6 and is mounted in water inlet 4, primarily to slowing down the water that water enters in valve chamber 3
Pressure and flow velocity (the predominantly speed of water level rising), it is ensured that the air in valve chamber 3 can all be discharged；Due to the water in exhaust valve
Hydraulic pressure and flow velocity in pressure and velocity ratio pipeline is much lower, so air can also be guaranteed in the connection through piping and exhaust valve
When mouth, air can be entered quickly in exhaust valve.The annular magnet 7 is mounted on gas vent 5, and annular magnet 7 wraps
Wrap up in flexible sealing strip 8；The floating ball 2 is magnetic floating ball, different with the magnetism of annular magnet 7, in the buoyancy of water
Under can float on the surface, and the surface of floating ball 2 is provided with one layer of rubber 9, magnetic between annular magnet 7 and floating ball 2 is inhaled
Gravitation is the 4/5 of the gravity of floating ball 2, and under the double action of magnetic attracting force and buoyancy, the rubber 9 on 2 surface of floating ball can be very
Good combines with sealing strip 8, ensure that the leakproofness between them, and floating ball 2 can be very after water level decreasing in valve chamber
Readily it is detached from the constraint of annular magnet 7.
The hydraulic pressure that the utility model uses slows down plug 6 as cylinder, and the upper and lower ends that hydraulic pressure slows down plug 6 are provided with grid,
It is internal filled with steel ball or rubble, reduces water by steel ball or rubble and enters pressure and flow velocity in valve chamber 3.
Although the specific embodiment of the utility model is described in detail and is illustrated above, it should be noted that
Be that we can make various changes and modifications the embodiment above, but these without departure from the utility model spirit and
Range documented by the attached claims.
