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 pressure relief valve, 8. wear water-cooling apparatus, 9. back pool, 10. return duct.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
The utility model provides a kind of little bar to wear 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, on described feed pipe, be provided with 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.By operating personnel, 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.
The operating personnel of production scene, the steel grade according to knowhow to certain specific standard, generally adopts specific cooling water amount and fixing cooling water pressure, to keep producing the stability of screw-thread steel performance.When the water consumption of water-cooling apparatus 8 and the output of constant speed supply-water pump 2 when uneven (water yield providing as constant speed supply-water pump is greater than and wears the about 40m3/h of water-cooling apparatus water consumption) are provided, 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, avoids supply-water pump 2 and equipment to damage because pressure is excessive.
Described feed pipe of the present utility model 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, in order to guarantee that steel can be simultaneously cooling, and guarantee the stability of each performance when cooling, described branch feed pipe 4 is four, described in wear water-cooling apparatus 8 be four and respectively Yu Sige branch feed pipe 4 connect.
If cooling water is directly discharged in natural environment, not only wasted water resource, also can pollute natural environment, the utility model 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, upper strata cooling water, by 2 recyclings of constant speed supply-water pump, continues steel to carry out cooling.
Described in of the present utility model, hold and press relief valve 7 to be arranged on branch's feed pipe 4, described holding presses the corresponding back pool 9 of discharge outlet of relief valve 7 to arrange, 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, on described main-supply 3, be also provided with flow control valve 5, flow control valve 5 is for regulating the water consumption of wearing water-cooling apparatus 8, on described branch feed pipe 4, be also provided with Pressure gauge 6, the pressure showing 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 utility model, when concrete use, is being produced early stage, and the pre-set pressure of pressing relief valve 7 of holding, guarantees to hold and press the setting pressure of relief valve 7 a little more than the pressure of wearing water-cooling apparatus 8 waters of 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 are adjusted to the water requirement of wearing water-cooling apparatus 8 water consumption of the screw-thread steel of producing certain steel grade by controlling flow control valve 5.
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 showing 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.
Press relief valve 7 wearing on the main-supply 3 of water-cooling apparatus 8 to increase to hold, 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 wearing the water requirement of water-cooling apparatus 8 to cause the phenomenons such as supply-water pump motor frequent breakage.
The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
