Specific embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
Refering to what is shown in Fig. 1, the invention discloses a kind of valve body structures of oil-stain-preventing blocking comprising have spool 1, valve body 2
With connecting rod 3, in which:
With reference to shown in Fig. 2,3,4,5,6, spool 1 goes out including barrier assembly 11, air inlet 12, outer ring venthole 13, inner ring
Stomata 14 and small air inlet hole 15, spool 1 are tapered rotary table, in which:
Air inlet 12 and outer ring venthole 13 are oppositely arranged on 1 circumferential side wall of spool, and inner ring venthole 14 is arranged in valve
The end of core 1, inner ring venthole 14 are vertically arranged with air inlet 12.The outer ring venthole 13 is with the inner ring venthole
14 are the center of circle and are 90 ° upwards with air inlet 12 and are obliquely installed clockwise, and tilt angle is 1 °~90 °, and the present embodiment is clockwise
Tilt angle be 80 °
Barrier assembly 11 include hold chute 111 and protrusion 112, protrusion 112 setting hold chute 111 on, protrusion 112 it is interior
Portion is equipped with interior recess 1121, and spool 1 is equipped with small air inlet hole 15, and small air inlet hole 15 is arranged in the interior recess 1121 of protrusion 112
The heart, small air inlet hole 15 be the center of circle with inner ring venthole 14 and be 90 ° upwards with air inlet 12 and be obliquely installed counterclockwise, small air inlet hole
15 form acute angle with the air inlet 12, and tilt angle is 1 °~90 °, and the tilt angle that the present embodiment is counterclockwise is 21 °.It is convex
The outside for playing 112 is equipped with outer convex 1122, therefore the cross section of protrusion 112 is at the bulge loop of " M " font of indent evagination, interior recess
1121 be cone, and conical interior recess 1121 can make combustion gas be flowed into rapidly in small air inlet hole 15 at swirl shape, outside
Convex 1122 is come at mountain range formula protrusion, forms isolation strip with chute 111 is held, two excessive sulphur can be kept in and be isolated in isolation strip
Change molybdenum lubricating grease and molybdenum disulphide grease with the impurity such as greasy filth are formed long afterwards, prevent impurity flow into 1121 at indent block into
Gas aperture 15.The height of protrusion 112 is lower than the depth for holding chute 111, therefore there is no interference when spool 1 and valve body 2 cooperate,
Rotation is smooth.
With reference to shown in Fig. 1,2,7,8, valve body 2 is equipped with rotating drum 21, inlet channel 22, outer ring outlet passageway 23 and inner ring and goes out
Gas channel 24, rotating drum 21 are tapered chamber, and the size of rotating drum 21 and the shape of spool 1 are mutually matched, and spool 1 is rotating
Rotation in chamber 21.Air inlet 12, small air inlet hole 15 are communicated with inlet channel 22, outer ring venthole 13 and 23 phase of outer ring outlet passageway
Logical, inner ring venthole 14 is communicated with inner ring outlet passageway 24.
With reference to shown in Fig. 1,8, connecting rod 3 is connected to the end of spool 1, and the linkage spool 1 of connecting rod 3 rotates.
With reference to shown in Fig. 1,2,7,8, assembly in use, spool 1 be assemblied in on the rotating drum 21 of 2 taper chamber of valve body,
Valve body 2 is equipped with inlet channel 22, outer ring outlet passageway 23 and inner ring outlet passageway 24, inlet channel 22, outer ring outlet passageway
23 and inner ring outlet passageway 24 be connected to the rotating drum 21 of valve body 2, and the air inlet 12, small air inlet hole of its position and spool 1
15, outer ring venthole 13, inner ring venthole 14 is corresponding, when in use, pivot link 3, connecting rod 3 with movable valve plug 1 valve body 2 rotation
Turn the rotation of chamber 21, the through-hole of its spool 1 is connected with corresponding air flue, combustion gas flows into burner combustion work.When adjusting firepower,
The through-hole of rotational valve core 1, the different pore size on spool 1 is connected with corresponding air flue, on spool 1 the different through-hole in aperture its flow through
Throughput it is different, cause the firepower of burner also different.So the accuracy guarantee of the through-hole accurate tune of valve body on spool 1
Control, the unimpeded of air flue ensure that burner normal combustion, avoid suddenly big or suddenly small, unstable combustion.However in actual use, it is
Making the smooth rotation of spool 1, durable use often coats one layer of thin molybdenum disulphide grease on the surface of taper valve core 1, due to
The molybdenum disulphide grease quantity of painting up is uncontrollable, and after of long duration, natural packing influences aperture on the through-hole wall of spool 1
Precision and blast tube area, especially influence the small air inlet hole 15 of spool 1 so that interior ring flame firepower adjust not
Standard, precision are deteriorated, or even suddenly big or suddenly small, the unstable combustion that flare occurs, and burning is fuzzy, therefore the protrusion 112 of barrier assembly 11
Outer convex 1122 forms isolation strip with chute 111 is held, and excessive molybdenum disulfide lubrication can be kept in and be isolated in the isolation strip of formation
Rouge and molybdenum disulphide grease are prevented impurity from flowing into 1121 at indent and are blocked small air inlet hole with the impurity such as greasy filth are formed long afterwards
15, so that 15 air inlet of small air inlet hole of spool 1 is accurate, firepower adjusts precision and gets higher, flameholding.
The above embodiments are merely illustrative and not limiting of the invention, therefore all according to described in present patent application range
The equivalent change or modification done of method, be included in the scope of the patent application of the present invention.
