Abstract
The utility model relates to a kind of water under high pressure pre-water filling system automatically, comprise high-pressure flush pipeline and preliminary filling water lines, the input of described high-pressure flush pipeline is connected with water under high pressure, and the input of described preliminary filling water lines is connected with low-pressure water, and output is connected with high-pressure flush pipeline; Described high-pressure flush pipeline is provided with high-pressure pneumatic stop valve; Described preliminary filling water lines is provided with low-pressure pneumatic stop valve and check valve successively.The utility model extends the service life of pneumatic stopping valve, greatly reduces cost.
Description
Technical field
The utility model relates to high pressure descaling technical field, particularly relates to a kind of water under high pressure pre-water filling system automatically.
Background technology
The factory that the rolling hot slabs such as Wide and Thick Slab factory and hot rolling mill are shaping, when high-pressure water descaling, as shown in Figure 1, generally all adopts preliminary filling water lines to connect water under high pressure, and uses restricting orifice A to be used for pre-water-filling by after water under high pressure step-down.The shortcoming of this method is: water under high pressure in pressure reduction and water under high pressure bath time very frequent to backwashing of restricting orifice A and high-pressure pneumatic stop valve B, thus greatly reduce the life cycle of restricting orifice and high-pressure pneumatic stop valve, restricting orifice and pneumatic stopping valve is caused to be changed frequent, cost is higher, and water under high pressure is very big etc. by noise during restricting orifice.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of water under high pressure pre-water filling system automatically, extends the service life of pneumatic stopping valve, greatly reduces cost.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of water under high pressure pre-water filling system automatically, comprise high-pressure flush pipeline and preliminary filling water lines, the input of described high-pressure flush pipeline is connected with water under high pressure, the input of described preliminary filling water lines is connected with low-pressure water, and output is connected with high-pressure flush pipeline; Described high-pressure flush pipeline is provided with high-pressure pneumatic stop valve; Described preliminary filling water lines is provided with low-pressure pneumatic stop valve and check valve successively.
Described high-pressure flush pipeline is also provided with the first hand stop valve.
Described preliminary filling water lines is also provided with the second hand stop valve.
Also safety valve is provided with between described low-pressure pneumatic stop valve and check valve.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model eliminates and is easy to damage and the higher restricting orifice of cost, high-pressure pneumatic stop valve is replaced with low-pressure pneumatic stop valve, be conducive to the use cost of saving preliminary filling water lines; Use check valve to stop water under high pressure backwashing to preliminary filling water lines, not only achieve the automatically pre-water-filling in use procedure, and substantially increase the service life of pneumatic stopping valve; During pre-water-filling, noise disappears substantially, is conducive to optimizing work on the spot environment.

Fig. 2 is structure principle chart of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment of the present utility model relates to a kind of water under high pressure pre-water filling system automatically, as shown in Figure 2, comprise high-pressure flush pipeline 1 and preliminary filling water lines 2, the input of described high-pressure flush pipeline 1 is connected with water under high pressure, the input of described preliminary filling water lines 2 is connected with low-pressure water, and output is connected with high-pressure flush pipeline 1; Described high-pressure flush pipeline 1 is provided with high-pressure pneumatic stop valve 11; Described preliminary filling water lines 2 is provided with successively low-pressure pneumatic stop valve 21 and check valve 22.Described high-pressure flush pipeline 1 is also provided with the first hand stop valve 12.Described preliminary filling water lines 2 is also provided with the second hand stop valve 23.Safety valve 24 is also provided with between described low-pressure pneumatic stop valve 21 and check valve 22.
Preliminary filling water lines of the present utility model directly connects low-pressure water, changes and uses restricting orifice by the mode of water under high pressure step-down in the past; Check valve is used for water under high pressure pipeline and low pressure preliminary filling water lines being separated when water under high pressure is washed by water, thus has stopped water under high pressure backwashing to preliminary filling water lines; And utilize the pressure reduction between high-low pressure pipeline to realize pre-water-filling automatically, when high-pressure flush, high-pressure flush pipeline pressure is greater than preliminary filling water lines, closed check valve, after high-pressure flush terminates, high-pressure water valve is closed, and high-pressure flush pipeline pressure is lower than preliminary filling water lines, and one-way valve opens also carries out pre-water-filling to high-pressure flush pipeline; Two hand stop valves are all for manual-lock pipeline separately; Pneumatic stopping valve in preliminary filling water lines is changed to low pressure valve by high pressure valve, for the opening and closing of preliminary filling water lines remote controlled during upkeep operation; Safety valve is used for protecting low-pressure water pipeline when failure of check valve.
When testing, pneumatic stopping valve was changed once by former half a year, was optimized in present 5 years non-maintaining, and noise also disappears substantially simultaneously, owing to eliminating restricting orifice, cost is significantly reduced.
Be not difficult to find, the utility model eliminates and is easy to damage and the higher restricting orifice of cost, high-pressure pneumatic stop valve is replaced with low-pressure pneumatic stop valve, is conducive to the use cost of saving preliminary filling water lines; Use check valve to stop water under high pressure backwashing to preliminary filling water lines, not only achieve the automatically pre-water-filling in use procedure, and substantially increase the service life of pneumatic stopping valve; During pre-water-filling, noise disappears substantially, is conducive to optimizing work on the spot environment.
