Description
Technical field
A kind of valve gate technology is the utility model is related to, particularly：A kind of improved check damper.
Background technology
Since reform and opening-up, Chinese national economy obtains rapid growth, has turned into current with " scientific and technical innovation, autonomous innovation "
The main flow of domestic industry development, " strong, the middle Guoqiang of science and technology " turn into the process for promoting China's scientific and technological revolution, and China's industry is just progressively
Develop to intensive style, energy-saving and emission-reduction, low-carbon, the intelligentized direction of high-tech.With the fast development of China's machinery industry, valve
Use it is more and more extensive, the requirement more and more higher to sealing property.The valve body of existing check-valves is connected with rocking bar moving part
The pad at place is all to use metal material, using easy corrosion after a period of time, influences the flexibility of check-valves flap rotation, makes
Into flap and valve seat blow-by, check-valves leakage accident can be caused when serious；And use the pad of more corrosion resistant copper product
Piece, European client can not receive again.Therefore, in order to solve this problem, R＆D institution and science and technology in enterprise personnel are continuous
Research, explore, using modern science and technology, a kind of check-valves is improved, although some progress are technically achieved, in reality
Border remains the technical problem not yet overcome in using.
The content of the invention
The purpose of this utility model is to overcome the above insufficient, there is provided a kind of improved check damper, the check-valves use material
Material technical principle designs.With intensity height, the characteristic that anti-wear performance is good, antifatigue, anti-leak result is good.Graphite wound gasket
It is made of graphite material and 114 anti-elater, corrosion will not occur in long-term use for graphite wound gasket, do not interfere with flap and turn
Dynamic flexibility, the sealing of check-valves is ensure that, improve the security of check-valves.
Technical scheme is used by the utility model solves its technical problem：Contain valve body, valve seat, flap, rocking bar, valve
Plate pad, valve plate nut, rocker pins, bonnet, graphite wound gasket, plug screw, valve body are cylindrical shape, and there is a cylindrical hole at center,
Valve inner is provided with an annular valve seat, and a flap is provided with the right side of valve seat, and a rocking bar, rocking bar right side are provided with the right side of flap
Provided with a valve plate pad, a flap nut is provided with the right side of valve plate pad, a rocker pins are provided with the top of rocking bar, are set in front of rocker pins
There is a graphite wound gasket, graphite wound gasket is compressed by plug screw, is provided with a bonnet on the upside of valve body, is formed a kind of modified and stop
Return valve.
Technical principle is used by the utility model solves its technical problem：The check-valves is set using material technology principle
Meter is formed, and graphite wound gasket is made using graphite material with 114 anti-elater, and graphite material has very strong in most media
Corrosion resistance, corrosion will not occur in long-term use, not interfere with the flexibility of flap rotation, it is ensured that flap is closing with valve seat
Closely connected during closed state, ensure that the sealing of check-valves, improve the security of check-valves.
The utility model beneficial effect is：The check-valves is designed using material technology principle, and graphite wound gasket uses
Graphite material is made with 114 anti-elater, and corrosion will not occur in long-term use for graphite wound gasket, does not interfere with flap rotation
Flexibility, the sealing of check-valves is ensure that, improve the security of check-valves.
Brief description of the drawings
Here is that the present invention is further described in conjunction with the accompanying drawings and embodiments：
Fig. 1 is a kind of structural representation of improved check damper；
Fig. 2 is a kind of partial enlarged drawing of improved check damper.
In Fig. 1,2：1. valve body, 2. valve seats, 3. flaps, 4. rocking bars, 5. valve plate pads, 6. valve plate nuts, 7. rocker pins, 8.
Bonnet, 9. graphite wound gaskets, 10. plug screws.
Embodiment
In Fig. 1,2：A kind of improved check damper is by valve body 1, valve seat 2, flap 3, rocking bar 4, valve plate pad 5, valve plate nut
6th, rocker pins 7, bonnet 8, graphite wound gasket 9, plug screw 10 form, and valve body 1 is cylindrical shape, and there are a cylindrical hole, valve in center
The inside of body 1 is provided with an annular valve seat 2, and the right side of valve seat 2 is provided with a flap 3, and the right side of flap 3 is provided with a rocking bar 4, rocking bar
4 right sides are provided with a valve plate pad 5, and the right side of valve plate pad 5 is provided with a flap nut 6, and the top of rocking bar 4 is provided with a rocker pins 7, shaken
The front of lever pin 7 is provided with a graphite wound gasket 9, and graphite wound gasket is compressed by plug screw 10, and the upside of valve body 1 is provided with a bonnet 8,
Form a kind of improved check damper.
The check-valves is designed using material technology principle, and graphite wound gasket 9 uses graphite material and 114 anti-elater systems
Into graphite wound gasket 9 has very strong corrosion resistance in most media, and corrosion will not occur in long-term use, will not
The flexibility that flap 3 rotates is influenceed, the sealing of check-valves is ensure that, improves the security of check-valves.
