The accompanying drawing explanation
Fig. 1 is the structure chart that the little bar of the present invention is worn the water cooling stabilising arrangement.
In figure, 1. pump house, 2. supply-water pump, 3. main-supply, 4. branch's feed pipe, 5. flow control valve, 6 Pressure gauges, 7. hold the pressure relief valve, 8. wears water-cooling apparatus, 9. back pool, 10. return duct.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, so that those skilled in the art can better understand the present invention also, can be implemented, but illustrated embodiment is not as a limitation of the invention.
The invention provides a kind of little bar and wear the water cooling stabilising arrangement, include supply-water pump 2 and wear water-cooling apparatus 8, described supply-water pump 2 with wear water-cooling apparatus 8 and be connected by feed pipe, be provided with on described feed pipe and hold pressure relief valve 7.
Described supply-water pump 2 is constant speed supply-water pump 2, and described constant speed supply-water pump 2 operated by rotary motion, in pump house 1, in the present embodiment, are provided with a plurality of supply-water pumps 2 in pump house 1, and by longer feed pipe, the water-cooling apparatus 8 of wearing to production scene supplies water a plurality of supply-water pumps 2.According to wearing the required water yield of water-cooling apparatus 8, confirm the number of units of the supply-water pump 2 of unlatching by operating personnel.
The operating personnel of production scene, the steel grade according to knowhow to certain specific standard, generally adopt specific cooling water amount and fixing cooling water pressure, to keep producing the stability of screw-thread steel performance.When the output of the water consumption of wearing water-cooling apparatus 8 and constant speed supply-water pump 2 is uneven (water yield provided as the constant speed supply-water pump is greater than and wears the about 40m3/h of water-cooling apparatus water consumption), unnecessary cooling water can make the pressure of feed pipe raise, when hydraulic pressure surpasses the setting value of holding pressure relief valve 7, hold and press relief valve 7 automatically to open, unnecessary cooling water is discharged, the constant voltage of assure feed water pipeline, avoid supply-water pump 2 and equipment to damage because pressure is excessive.
Described feed pipe of the present invention is comprised of main-supply 3 and a plurality of branches feed pipe 4, and a plurality of described branches feed pipe 4 is connected with main-supply 3 respectively.In specific embodiment, can be simultaneously cooling in order to guarantee steel, and guarantee the stability of each performance when cooling, described branch feed pipe 4 is four, it is described that to wear water-cooling apparatus 8 be four and with four branch's feed pipes 4, be connected respectively.
If directly be discharged in natural environment by cooling water, not only wasted water resource, also can pollute natural environment, the present invention is provided with back pool 9 in described bottom of wearing water-cooling apparatus 8, described back pool 9 is connected with pump house 1 by return duct 10, and cooling water is collected and refluxed at back pool 9 and enters pump house 1, after precipitation, the upper strata cooling water, by 2 recyclings of constant speed supply-water pump, continues to carry out cooling to steel.
Described holding of the present invention presses relief valve 7 to be arranged on branch's feed pipe 4, the described corresponding back pool 9 of the discharge outlet of pressing relief valve 7 of holding arranges, when the hydraulic pressure of branch's feed pipe 4 is excessive, hold and press relief valve 7 automatically to open cooling water drainage in back pool 9, guarantee the stability of feed pipe hydraulic pressure, also be provided with flow control valve 5 on described main-supply 3, flow control valve 5 is worn the water consumption of water-cooling apparatus 8 for adjusting, also be provided with Pressure gauge 6 on described branch feed pipe 4, the pressure shown when Pressure gauge 6 is higher than predefined while holding the pressure of pressing relief valve 7, hold and press relief valve 7 to open, unnecessary cooling water is entered to back pool 9.
The present invention, when specifically using, is producing early stage, and the pre-set pressure of pressing relief valve 7 of holding guarantees to hold the pressure of wearing water-cooling apparatus 8 waters of the setting pressure of pressure relief valve 7 a little more than production requirement.
When starting to produce, constant speed supply-water pump 2 is opened, by main-supply 3, to wearing water-cooling apparatus 8, supply water.Operating personnel will wear water-cooling apparatus 8 water requirement by controlling flow control valve 5 is adjusted to the water consumption of the screw-thread steel of producing certain steel grade.
When screw-thread steel moves to while wearing water-cooling apparatus 8, to wear water under high pressure double thread steel in water-cooling apparatus 8 and carry out coolingly, cooling water flows into and wears in the back pool 9 under water-cooling apparatus 8, in back pool 9 is back to pump house 1, reuses.
When if the water yield that constant speed supply-water pump 2 the provides cooling water inflow required with producing screw-thread steel do not mate, the instantaneous rising of pressure meeting of main-supply 3, the numeral shown when Pressure gauge is higher than holding while pressing the pressure that relief valve 7 sets, hold and press relief valve 7 automatically to open, the unnecessary water under high pressure that constant speed supply-water pump 2 is provided enters back pool 9, and then reaches the balance that supplies water and need water.
Increase to hold on the main-supply 3 of wearing water-cooling apparatus 8 and press relief valve 7, aborning, can remain the water supply of constant speed supply-water pump 2 and wear the balance between water-cooling apparatus 8 waters, avoid in the past output due to constant speed supply-water pump 2 to be greater than the water requirement of wearing water-cooling apparatus 8 and caused the phenomenons such as supply-water pump motor frequent breakage.
The above embodiment is only the preferred embodiment for absolutely proving that the present invention lifts, and protection scope of the present invention is not limited to this.Being equal to that those skilled in the art do on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
