Preceding reversable mill emulsion transfer pipeline is long.In actual use, the two-sided arrangement of the Emulsified liquid nozzle of reversable mill, according to
Passage difference realizes that emulsion commutates with the keying of Pneumatic butterfly valve, but because Pneumatic butterfly valve is pressed when opening before and after butterfly valve in pipeline
Power difference is larger, and emulsion transfer pipeline is long, pipeline vibration is caused in Pneumatic butterfly valve commutation action acutely, butterfly valve seal group
Part is larger by impacting.Passage changed frequent when being worked due to reversable mill, every about Pneumatic butterfly valve action one in ten minutes or so
Secondary, above reason makes the butterfly valve life-span reduce significantly.More seriously because the seal assembly of Pneumatic butterfly valve is damaged, breast when closing butterfly valve
Change liquid leakage, had a strong impact on pressure, the flow in conveyance conduit, cause draught pressure increase, the increase of plate form control difficulty, and
Belt steel surface emulsion residue is easily caused, a series of surface quality problems such as yellow blackspot, aberration are produced, after also considerably increasing
The cost of continuous process processing.Therefore the vibration of emulsion transfer pipeline how is reduced, so as to avoid leakage and the damage of Pneumatic butterfly valve
It is bad, it is ensured that be normally carried out and the product quality of production are urgent problems to be solved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of commutation of reversable mill emulsion transfer pipeline and subtracted
Vibrating device, this vibration absorber can reduce the vibration of emulsion transfer pipeline, it is to avoid the leakage of Pneumatic butterfly valve, extend pneumatic butterfly
Valve service life, it is ensured that being normally carried out for production, improves product quality.
Solving the technical scheme of above-mentioned technical problem is：
A kind of commutation vibration absorber of reversable mill emulsion transfer pipeline, it includes a set of main pipe rail and controls Pneumatic butterfly valve
With two sets of pneumatic commutation butterfly valves, main pipe rail control Pneumatic butterfly valve is arranged in emulsion conveying main line, two sets of pneumatic commutation butterflies
Valve is separately mounted in emulsion delivery branch pipe road, and its improvements is that it adds vibration damping bypass and the pneumatic butterfly of a set of vibration damping
Valve, one end of vibration damping bypass is connected with emulsion conveying main line, and tie point is located at main pipe rail control Pneumatic butterfly valve and emulsification
On emulsion conveying main line between liquid pump outlet, the other end of vibration damping bypass is connected with absolute oil case, vibration damping Pneumatic butterfly valve
In vibration damping bypass.
The commutation vibration absorber of above-mentioned reversable mill emulsion transfer pipeline, main pipe rail control Pneumatic butterfly valve, two sets
Pneumatic commutation butterfly valve, vibration damping Pneumatic butterfly valve are constituted by magnetic valve and Pneumatic butterfly valve, and magnetic valve is connected with Pneumatic butterfly valve, electromagnetism
Valve is arranged in emulsion transfer pipeline, and Pneumatic butterfly valve is connected with compressed air line.
The beneficial effects of the utility model are：
The utility model conveys in emulsion and vibration damping bypass is added between main line and absolute oil case, pacifies in vibration damping bypass
Vibration damping Pneumatic butterfly valve is filled, when switching the emulsion supply of different rolling passes, vibration damping Pneumatic butterfly valve is first turned on, is then opening
Pneumatic commutation butterfly valve is opened, the vibration of emulsion transfer pipeline is eliminated.The utility model is simple in construction, easy to use, vibration damping effect
Fruit significantly, can effectively solve the pneumatic commutation butterfly valve of reversable mill emulsion transfer pipeline when opening before and after butterfly valve in pipeline
Pressure differential is larger, emulsion transfer pipeline it is long caused by pipeline vibration it is violent the problem of, improve the use longevity of Pneumatic butterfly valve
Life, makes the life-span of Pneumatic butterfly valve extend to more than 2 years from 3 months, tell on highly significant, greatlys save spare parts cost,
Also effectively reduce because emulsion reveals the product quality problem produced, it is ensured that being smoothed out for production, have to enterprise aobvious
The economic benefit of work.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows：Reversable mill 1, emulsion conveying main line 2, emulsion delivery branch pipe road 3, vibration damping bypass 4,
Absolute oil case 5, emulsion pump 6, main pipe rail control Pneumatic butterfly valve 7, pneumatic commutation butterfly valve 8, vibration damping Pneumatic butterfly valve 9, compressed air hose
Road 10, safe discharge pipeline 11.
Embodiment
The utility model is made up of vibration damping bypass 4, vibration damping Pneumatic butterfly valve 9.
Shown in figure, one end of the emulsion conveying main line 2 of reversable mill 1 is connected with absolute oil case 5, and the other end passes through
Two emulsion delivery branch pipe roads 3 be connected to before the machine of reversable mill 1 and machine after.Main line 2 is conveyed in absolute oil case 5 and emulsion
Junction install emulsion pump 6, by emulsion be driven into emulsion conveying main line 2 in.Pacify in emulsion conveying main line 2
Main pipe rail control Pneumatic butterfly valve 7 is filled, for short time parking cut-out for breast.Pacify respectively in two emulsion delivery branch pipe roads 3
Pneumatic commutation butterfly valve 8 is filled, act as switching different rolling pass emulsion emission directions.In emulsion conveying main line 2 and only
Safe discharge pipeline 11 is also equipped between fuel tank 5.
Shown in figure, main pipe rail control Pneumatic butterfly valve 7 and two sets of pneumatic commutation butterfly valves 8 are respectively by magnetic valve and Pneumatic butterfly valve
Composition, magnetic valve is connected with Pneumatic butterfly valve, and magnetic valve is arranged in emulsion transfer pipeline, Pneumatic butterfly valve and compressed air hose
Road 10 is connected.
Shown in figure, one end of increased vibration damping bypass 4 is connected with emulsion conveying main line 2, and tie point is located at total
Pipeline control Pneumatic butterfly valve 7 and emulsion pump 6 export between emulsion conveying main line 2 on, the other end of vibration damping bypass 4 with
Absolute oil case 5 is connected, and vibration damping Pneumatic butterfly valve 9 is arranged in vibration damping bypass 4.
Shown in figure, vibration damping Pneumatic butterfly valve 9 is also to be made up of magnetic valve and Pneumatic butterfly valve, and magnetic valve is connected with Pneumatic butterfly valve
