Description
Technical field
The invention belongs to metallurgical steel rolling equipment field, be specifically related to the commutation of a kind of bar mill roll cooling water pipe valve and eliminate vibrational system.
Background technology
100 tons of electric furnace rolling lines of Laiwu branch company of Shan Gang group are when debugging the roll cooling water of roughing and tandem rolling, when penstock switches, valve creates high vibration, finally causes valve to leak, the foundation bolt of fixed valve is pulled off, and support also occurs that many places are out of shape.
Be generally adopt expansion joint and U-shaped curved mode to alleviate impact in existing water lines, this mode is applicable in common water lines, and for commutating frequently, roll rolipass design water pipe is inapplicable.
Summary of the invention
The object of the invention is to provide for the deficiencies in the prior art a kind of bar mill roll cooling water pipe valve to commutate and eliminate vibrational system.
The technical solution adopted for the present invention to solve the technical problems is: vibrational system is eliminated in a kind of bar mill roll cooling water pipe valve commutation, comprise cistern, feed pipe, roll rolipass design shower nozzle and overflow pipe, described cistern is connected with roll rolipass design shower nozzle by feed pipe, operation roll of mill is provided with below roll rolipass design shower nozzle, feed pipe is provided with Pneumatic gate valve one, Pneumatic gate valve two and Pneumatic gate valve one are connected in parallel on feed pipe, feed pipe between Pneumatic gate valve one and suction pump is provided with hand stop valve, feed pipe after hand stop valve is provided with the bypass line be connected with Accumulator arrangements, bypass line is provided with Pneumatic gate valve three, Accumulator arrangements is connected with cistern by overflow pipe.
Particularly, described bypass line is connected on the feed pipe between hand stop valve and Pneumatic gate valve one.
Particularly, described Pneumatic gate valve three is positioned at the front end of Accumulator arrangements.
Particularly, described Accumulator arrangements is connected with electric switching valve.
Particularly, described electric switching valve comprises electromotive intake valve and electric flowing valve, and described electromotive intake valve is connected with bypass line, and described electric flowing valve is connected with overflow pipe.
The present invention is reasonable in design, structure is simple, draws a bypass line, connect the Accumulator arrangements of a constant volume in the porch of change-over valve, water kinetic energy during commutation is diverted in accumulator by accumulator, so just well alleviates the impact of water kinetic energy to valve and pipeline.After operated pneumatic valve steadily commutates, substantially increase the service life of valve, shorten the repair time, improve the operating efficiency of milling train.Roll coolant system after improving for the present invention, the service life of cooling water pipe also improves greatly because eliminating high vibration, and the cooling effect of breaker roll is also greatly improved simultaneously.The present invention is applied in hydraulic system, and the commutation of hydraulic valve platform is frequent, impacts very large, in hydraulic system, generally configure 4-6 group accumulator, can play fine protecting against shock effect fluid pressure line.

Detailed description of the invention
Be below specific embodiments of the invention, technical scheme of the present invention is described further, but protection scope of the present invention is not limited to these embodiments.Every do not deviate from the present invention's design change or equivalent substituting include within protection scope of the present invention.
As shown in Figure 1, vibrational system is eliminated in the commutation of a kind of bar mill roll cooling water pipe valve, comprise cistern 1, feed pipe 12, roll rolipass design shower nozzle 11 and overflow pipe 10, described cistern 1 is connected with roll rolipass design shower nozzle 11 by feed pipe 12, operation roll of mill 9 is provided with below roll rolipass design shower nozzle 11, feed pipe 12 is provided with Pneumatic gate valve 1, Pneumatic gate valve 25 and Pneumatic gate valve 1 are connected in parallel on feed pipe 12, feed pipe 12 between Pneumatic gate valve 1 and suction pump 2 is provided with hand stop valve 3, feed pipe 12 after hand stop valve 3 is provided with the bypass line 13 be connected with Accumulator arrangements 6, bypass line 13 is provided with Pneumatic gate valve 37, Accumulator arrangements 6 is connected with cistern 1 by overflow pipe 10.
Particularly, described bypass line 13 is connected on the feed pipe 12 between hand stop valve 3 and Pneumatic gate valve 1.
Particularly, described Pneumatic gate valve 37 is positioned at the front end of Accumulator arrangements 6.
Particularly, described Accumulator arrangements 6 is connected with electric switching valve.
Particularly, described electric switching valve comprises electromotive intake valve 14 and electric flowing valve 8, and described electromotive intake valve 14 is connected with bypass line 13, and described electric flowing valve 8 is connected with overflow pipe 10.
Press water is delivered to air operated reversing valve door Pneumatic gate valve one, Pneumatic gate valve two place by feed pipe by suction pump, before operated pneumatic valve commutation, the electromotive intake valve and the Pneumatic gate valve three that enter Accumulator arrangements are opened, Pneumatic gate valve one, Pneumatic gate valve two one of them close, one open, operation roll of mill just receives the cooling water spraying in cooling pipe and.Accumulator arrangements stores a part of press water in Pneumatic gate valve one, Pneumatic gate valve two commutation after terminating, and accumulator electric flowing valve is opened, and press water is let out back cistern by overflow pipe.
Accumulator arrangements is contained in the front end of milling train cooling change-over valve, its object utilizes Accumulator arrangements exactly, before operated pneumatic valve commutation, press water in water pipe is supplemented to Accumulator arrangements inside by bypass line, after commutation terminates, by overflow pipe, the press water in Accumulator arrangements is flow back to cistern, so just achieve the steady commutation of air operated reversing valve.
