Example 1:

referring to fig. 1-3, a check valve controlled emulsion shunting package comprises a storage box 1, a liquid inlet pipe 2, a shunting pipe 3, a nozzle 6, a check valve 4 and a hose 5, wherein the liquid inlet pipe 2 is communicated with the storage box 1, the shunting pipe 3 is connected with the storage box 1, the nozzle 6 is connected with the shunting pipe 3, the check valve 4 is arranged between the shunting pipe 3 and the nozzle 6, the hose 5 is made of flexible materials, and the hose 5 is arranged between the check valve 4 and the nozzle 6.

In addition to the emulsion system, the cold rolling mill set also has a purging device, and the purging device mainly functions to remove various residues on the surface of the strip steel. However, in the rolling process, if the operation of the emulsion system is stopped, the purging device also stops working according to the system control setting, but it is inevitable that residual emulsion in the emulsion split stream packet drops on a steel strip which is subsequently rolled due to the action of gravity, and the time difference between the purging device and the emulsion system stopping working is insufficient for cleaning the residual emulsion in the emulsion storage tank, so that the residual untreated emulsion can pollute the surface of the steel strip, form black spots, cause corrosion of the steel strip and influence the quality of a cold-rolled steel strip product.

In this embodiment, the check valve 4 controlled type emulsion split stream packet is composed of a liquid inlet pipe 2, an emulsion storage tank 1, a split pipe 3, a check valve 4, a joint, a hose 5, a spray pipe and a nozzle 6. Nine shunt holes are formed in the bottom of the emulsion storage box 1, the positions and the arrangement of the nine shunt holes are mainly determined according to the equipment structure and the lubricating process, and pipelines led out from the nine shunt holes and the nozzle 6 are ensured not to interfere with each other. Then the shunt pipe 3 is welded at the shunt hole, the one-way valve 4 is arranged at the outlet of the shunt pipe 3, one end of the joint is connected with the one-way valve 4, the other end of the joint is connected with one end of the hose 5, and finally the other end of the hose 5 is connected with the corresponding emulsion spray pipe and the corresponding nozzle 6, so that a complete emulsion shunt and spray device is finally formed.

The working principle is as follows: the emulsion system provides the emulsion, and the emulsion passes through feed liquor pipe 2 and enters into emulsion storage box 1 in, and incasement liquid gets into shunt tubes 3 through each diffluence hole, forms certain pressure, and when the pressure value reached system setting's numerical value, check valve 4 opened automatically under the pressure effect, and the emulsion flows in each hose 5, and rethread hose 5 gets into the emulsion and spouts the device that drenches, and this reposition of redundant personnel of emulsion has just been accomplished. When the emulsion system stops working, the emulsion storage box 1 stops conveying the emulsion, the emulsion flowing into each shunt pipe 3 is reduced, the pressure in the pipe is reduced, the working pressure of the check valve 4 cannot be reached, the check valve 4 is closed, the emulsion conveying pipeline is cut off, and the emulsion cannot enter the emulsion spraying device any more. The residual emulsion in the hose 5 and the spray device is also purged by the purging device which is then stopped. The equipment can not only effectively stop the supply of the emulsion in time, but also avoid the condition that the residual emulsion drips to pollute the strip steel.

The production environment based on the cold rolling mill is not suitable for electromagnetic equipment to work, and the structure of an electric valve or an electromagnetic valve is adopted, so that although the aging is quicker in the aspect of stopping emulsion supply, the price of the parts is higher, the service life of the parts is shortened in the high-temperature and high-humidity service environment, the cost is high, the maintenance difficulty is high, and the parts are not suitable for batch use. Meanwhile, the spraying angle needs to be adjusted according to actual operation, a complex adjusting device is high in cost and needs to be designed independently, the problems are avoided well through the flexible hose 5, and meanwhile, the maintenance cost and the difficulty are low.

The circular structure is favorable for the emulsion to evenly flow to each shunt tube 3, reduces the liquid supply difference between the shunt tubes 3, and realizes better emulsion spraying effect. Meanwhile, the emulsion shunting packet can timely stop the supply of the emulsion, the supply of each nozzle 6 is required to be ensured to be consistent as much as possible, the difference is small, the consumption of the emulsion is favorably controlled, and the requirement of spraying is ensured to be met, so that all other nozzles 6 which are larger than the minimum supply nozzle 6 belong to over supply, and waste is caused. Therefore, the symmetrical design is adopted as much as possible, and the circular structure is used for ensuring the supply consistency of the shunt tubes 3.

As the further optimization of scheme, shunt tubes 3 and storage box 1 vertical setting, shunt tubes 3 are located the both sides of feed liquor pipe 2, and feed liquor pipe 2 sets up with shunt tubes 3 vertical setting. The shunt tubes 3 avoid the liquid inlet pipe 2 to be designed, and liquid channeling exists in the liquid inlet pipe 2, but the liquid inlet of the shunt tubes 3 is uneven and unsmooth. In order to realize the balanced supply of each shunt tube 3, the liquid is prevented from directly impacting the liquid inlet of the shunt tube 3, the phenomenon of impact blockage is prevented, and the emulsion can uniformly flow to each shunt tube 3.

As a further optimization of the scheme, the device also comprises a spray pipe, wherein the spray pipe is arranged between the spray nozzle 6 and the hose 5, and the maximum inner diameter of the spray pipe is less than or equal to the inner diameter of the hose 5.
