Detailed Description
The invention is further described below with reference to the following figures and specific examples.
A gas balance valve for a gas proportioning bin, comprising:
the main body ring 1 is annular, a balance cavity 8 is arranged at the center of the main body ring 1, the balance cavity 8 is a circular through hole, leather pads 2 are respectively arranged on two sides of the main body ring 1, a cover plate 3 is arranged on the outer side of each leather pad 2, and the peripheries of the main body ring 1, the leather pads 2 and the cover plate 3 are sealed through sealing bolts 5; the middle part of the leather pad 2 is provided with a leather pad bulge 12, the leather pad bulge 12 bulges towards the cover plate 3, the middle part of the cover plate 3 is provided with a boss 9, the boss 9 is hollow and provided with a movable bowl 4, the outer side of the boss 9 is provided with an air inlet 6 and an air outlet 7, the inner wall of the boss 9 is attached to the outer wall of the movable bowl 4, the bottom of the movable bowl 4 is a plane, the upper part of the movable bowl is a thin-walled ring, and the outer diameter of the movable bowl 4 is larger than the diameter of the balance cavity 8; main part ring 1 evenly sets up a plurality of main part ring bolt holes 11 all around, and apron 3 evenly sets up a plurality of apron bolt holes 10 all around, and the quantity of apron bolt hole 10 and main part ring bolt hole 11 is the same, and the position corresponds.
The thickness of the body ring 1 is greater than 1 cm. The leather pad bulge 12 of the leather pad 2 is in a ring shape, the diameter of the leather pad bulge 12 is larger than that of the balance cavity 8, and the leather pad bulge 12 and the balance cavity 8 are concentric. The boss 9 of the cover plate 3 is cylindrical, and the axis is concentric with the balance cavity 8 and is vertical to the main body ring 1. The outer diameter of the movable bowl 4 is larger than that of the leather pad bulge 12, and the leather pad bulge 12 is in a ring shape. The number of the cover plate bolt holes 10 and the body ring bolt holes 11 is one of 8, 12, 16, and 20. The periphery of the main body ring 1 is a plane and is respectively jointed with the leather pads 2, and the peripheries of the cover plates 3 at the two sides are planes and are respectively jointed with the leather pads 2. The air inlet 6 is positioned at the center of the boss 9 and is respectively concentric with the movable bowl 4 and the balance cavity 8.
The air inlets 6 on the cover plates 3 on the two sides of the main body ring 1 are respectively communicated with different kinds of gas to be mixed, the gas of the air inlets 6 respectively impacts the corresponding movable bowls 4, and the movable bowls 4 move up and down on the inner walls of the cover plates 3. The leather packing that activity bowl 4 extruded on the leather packing 2 is protruding 12, and sealed gas chamber is constituteed to leather packing arch 12 and balanced chamber 8, because the protruding 12 setting of leather packing, the protruding 12 outside uplifts towards main part ring 1 of leather packing, and the gas volume in the gas chamber is sufficient, and at the extrusion in-process, the leather packing 2 of main part ring 1 both sides extrudees each other, can effectual realization balance effect. The inner wall of apron 3 is laminated to activity bowl 4, and the external diameter of activity bowl 4 is greater than the diameter of balanced chamber 8 simultaneously, effectively restricts the motion of activity bowl 4, can only be along the inner wall linear motion of apron 3, can not extruded again simultaneously in the balanced chamber 8. The balance effect is good, a multi-stage balance valve is not needed, the cost can be reduced, the size is reduced, and the economic benefit is improved.
The thickness of the main body ring 1 is larger than 1cm, so that the main body ring 1 has enough shock resistance. The leather pad bulge 12 of the leather pad 2 is in a ring shape, so that the force transmission with the movable bowl 4 is conveniently realized, the impact force of gas is effectively dispersed, and the balance of the two gases is utilized. The diameter is greater than the diameter of the balance cavity 8, and the movable bowl 4 is prevented from entering the balance cavity 8 and affecting balance. The leather pad bulge 12 is concentric with the balance cavity 8, and the stress is uniform. The boss 9 of apron 3 is cylindrical, and axle center and balanced chamber 8 are concentric to perpendicular to main part ring 1, the gaseous impact force of effective dispersion, the motion of restriction activity bowl 4 makes activity bowl 4 can only be linear motion, and then acts on leather packing arch 12 with the effort, realizes atmospheric pressure through the gaseous atmospheric pressure balance that realizes in extrusion leather packing arch 12 and the balanced chamber 8. The outer diameter of the movable bowl 4 is larger than that of the leather pad bulge 12, and the leather pad bulge 12 is in a circular ring shape, so that the acting force of the movable bowl 4 is effectively released to the leather pad bulge 12. The number of the cover plate bolt holes 10 and the main body ring bolt holes 11 is one of 8, 12, 16 and 20, the holes are uniformly distributed, sealing is facilitated, and gas in the leather pad 2 and the cover plate 3 is prevented from leaking in the leather pad protrusion 12 and the balance cavity 8. The periphery of the main body ring 1 is a plane and is respectively attached to the leather pads 2, the peripheries of the cover plates 3 on two sides are planes and are respectively attached to the leather pads 2, and therefore in the leather pad protrusions 12 and the balance cavity 8, gas in the leather pads 2 and the cover plates 3 is prevented from leaking. The air inlet 6 is positioned at the center of the boss 9 and is respectively concentric with the movable bowl 4 and the balance cavity 8, so that the gas of the air inlet 6 uniformly impacts the movable bowl 4, and the balance effect is effectively realized.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
