Abstract
The utility model discloses a cylinder iris type air valve, including deflector, floater, baffle, cavity screw rod, cylinder little valve, stop valve handle and disk seat, the little valve of cylinder is installed on the disk seat, cavity screw rod bottom end is connected with the baffle of installing on the valve body, and is provided with stopper and current -limiting buffer board on the cavity screw rod to be provided with big exhaust partition wall in current -limiting buffer board and cavity screw rod junction bottom, state the deflector and install on the valve body inside wall, and be provided with the floater between the deflector, the micro - gas vent of seting up on the little valve of cylinder, and micro - gas vent passes cavity screw rod connection floater through the hose, this cylinder iris type air valve, it increases by a current -limiting buffer on common type air valve basis, and when air valve internal -external differential pressure reached a certain setting value, current -limiting buffer was blown afloat, stopped up an amount of venting area, realized limiting the quantity of the exhaust to prevent that the exhaust takes place the cutout at the excessive speed and makes the water hammer up.
Description
Technical field
This utility model relates to air cock applied technical field, and especially a kind of cylinder iris type is empty
Air valve.
Background technology
Air cock, applies extremely widespread, external pressure in existing air cock in life produces
When difference is more than a certain setting value, exhaust effect is the strongest, it is impossible to reach to greatest extent to eliminate
The purpose of water hammer.
Utility model content
Prior art is difficult to meet the productive life needs of people, in order to solve asking of above-mentioned existence
Topic, the utility model proposes a kind of cylinder iris type air cock, its simple in construction, practicality
By force.
For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of cylinder every
Plate type air valve, including guide plate, ball float, dividing plate, hollow screw, the micro-valve of cylinder, cuts
Only valve handle and valve seat；The micro-valve of described cylinder is arranged on valve seat；Described hollow screw bottom
It is connected with the dividing plate being arranged on valve body, and in hollow screw, is provided with limited block and current limliting delays
Punching, and current limliting buffer board and bottom, hollow screw junction are provided with big exhaust partition；
Described guide plate of stating is arranged on valve body medial wall, and is provided with ball float between guide plate；Institute
State the trace air vent offered on the micro-valve of cylinder, and trace air vent passes hollow by flexible pipe
Screw rod connects ball float.
Further, described cylinder micro-valve outer end is provided with dust cap, net.
Further, described valve seat and valve body junction are provided with sealing ring；Described ball float and flexible pipe
Junction is provided with sealing gasket.
Compared with prior art, this utility model has the advantages that this cylinder iris type
Air cock, it increases by a current limliting buffer unit on the basis of plain edition air cock, when in air cock
When external differential reaches a certain setting value, current limliting buffer unit is blown afloat, and blocks a certain amount of aerofluxus
Area, it is achieved quantity-limited exhaust, in case aerofluxus too fast generation water hammer due to cavities collapsing.Typically can limit the quantity
Determine between 5%～20% of total leaving area or through hydraulic hammer calculation, and the low pressure of this valve is a large amount of
Suction, aerofluxus, high pressure micro degassing function are identical with plain edition；Overall structure is simple, and design is new
Grain husk, practical, it is easy to promote the use of.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is side view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment
Technical scheme be clearly and completely described, it is clear that described embodiment be only this
The a part of embodiment of utility model rather than whole embodiments.Based in this utility model
Embodiment, those of ordinary skill in the art are obtained under not making creative work premise
All other embodiments, broadly fall into the scope of this utility model protection.
Refer to Figure of description 1～2, in this utility model embodiment, a kind of cylinder iris type
Air cock, including guide plate 1, ball float 2, dividing plate 3, hollow screw 4, the micro-valve of cylinder 5,
Stop valve handle 6 and valve seat 7；The micro-valve of described cylinder 5 is arranged on valve seat 7；In described
Empty screw rod 4 bottom is connected with the dividing plate 3 being arranged on valve A, and sets in hollow screw 4
It is equipped with limited block 41 and current limliting buffer board 42, and in current limliting buffer board 42 and hollow screw 4
Bottom, junction is provided with big exhaust partition 43；Described guide plate 1 of stating is arranged in valve A
On sidewall, and between guide plate, it is provided with ball float 2；Offer on the micro-valve of described cylinder 5
Trace air vent 51, and trace air vent 51 is floating through hollow screw 4 connection by flexible pipe 8
Ball 2.
Further, described cylinder micro-valve 5 outer end is provided with dust cap, net 9.
Further, described valve seat 7 is provided with sealing ring 71 with valve A junction；Described floating
Ball 2 and flexible pipe 8 junction are provided with sealing gasket 21.
Action principle of the present utility model is: when in valve body, water level is gradually increasing, big ball float by
Gradually holding up big air vent dividing plate and closed hollow slide bar sealing surface, big exhaust partition is blocked after holding up
Big air vent, terminates a large amount of aerofluxus；Hollow slide bar sealing surface makes cylinder micro-valve top after closing
Piston decompression, float air cover board recovers closed mode, terminates trace aerofluxus；When a small amount of gas by
When gradually gathering, in valve body, water level can be gradually reduced, and big ball float buoyancy upwards also can be gradually lowered,
When buoyancy is less than ball float gravity, ball float moves down, and hollow slide bar hermetic seal joint is opened (this
Time big exhaust partition because thrust gas upwards is without falling), now gas is sliding by hollow
Bar, flexible pipe enter cylinder micro-valve upper piston cylinder, because upper lower piston exists difference in areas, thus
Float air cover board is pressed off again, and the micro-valve of cylinder starts to discharge gases at high pressure.When pipeline occurs
During negative pressure, big ball float, big exhaust partition fall, and open big air vent air-breathing.
To those skilled in the art, however this utility model is not limited to above-mentioned exemplary reality
Execute the details of example, and in the case of without departing substantially from spirit or essential attributes of the present utility model,
This utility model can be realized in other specific forms.Therefore, no matter from the point of view of which point,
Embodiment all should be regarded as exemplary, and be nonrestrictive, model of the present utility model
Enclose and limited by claims rather than described above, it is intended that will fall in claim
All changes in the implication of equivalency and scope are included in this utility model.Should will not weigh
Any reference during profit requires is considered as limiting involved claim.
The above, preferred embodiment the most of the present utility model, not in order to limit this practicality
Novel, every according to technical spirit of the present utility model, above example is made any trickle
Amendment, equivalent and improvement, should be included in the protection domain of technical solutions of the utility model
Within.
