Description

A kind of decompression water supply installation meeting different flow needs
Technical field
The utility model relates to water supply installation field, particularly relates to a kind of decompression water supply installation meeting different flow needs.
Background technology
In daily urban water supply process, be supplied to user after needing water under high pressure to reduce pressure, and the water system water supply volume that reduces pressure also exists larger difference.If depressurized system is in normal operative condition, now the output of system is less, if system is in improper water supply or accident working condition, water supply volume is now larger.Usual decompression water system is all design according under nominal situation condition; if when using depressurized system under ensureing improper or accident working condition; then need bigbore reducing valve; now change bigbore reducing valve with regard to needing into the reducing valve changing original depressurized system; but under normal operating condition, low discharge can produce larger Noise and vibration by during heavy caliber reducing valve.Therefore, need to design the decompression water system that can simultaneously can be used under different operating mode based on above-mentioned analysis.
Utility model content
The purpose of this utility model is to provide a kind of decompression water supply installation meeting different flow needs; this water supply installation adopts reducing valve reducing parallel connection decompression water system; both can ensure that low discharge supplied water under normal circumstances, can ensure again that the large discharge under improper or accident condition supplied water.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that a kind of decompression water supply installation meeting different flow needs, it comprises water source, water source is connected with water supply line, a water supply branch road and No. two water supply branch roads are parallel with after water supply line, a described water supply branch road is provided with a service valve, after a service valve, is provided with heavy caliber reducing valve, after heavy caliber reducing valve, be provided with No. two service valves.
Described No. two water supply branch roads are provided with No. three service valves, after No. three service valves, are provided with small-bore reducing valve, after small-bore reducing valve, be provided with No. four service valves.
Described No. two service valves are connected with user pipe with No. four service valves simultaneously, and user pipe is connected with user's water valve.
The bore of described small-bore reducing valve is 1/3 of heavy caliber reducing valve bore.
Set-pressure height 0.05MPa after set-pressure larger caliber reducing valve after described small-bore reducing valve.
The utility model has following beneficial effect:
By the heavy caliber reducing valve of two different bores in parallel on original pressure reducing circuit and small-bore reducing valve simultaneously for user provides decompression water system, due to set-pressure height 0.05MPa after set-pressure larger caliber reducing valve after small-bore reducing valve.When flow is less due to the difference of set-pressure after heavy caliber reducing valve and small-bore reducing valve, heavy caliber reducing valve cuts out, and small-bore reducing valve is opened, thus carries out low discharge water supply; When user pipe flow after valve increases, small-bore reducing valve resistance increases, and when head pressure loss is equivalent to 0.05MPa, heavy caliber reducing valve is opened, and now heavy caliber reducing valve and small-bore reducing valve work simultaneously, augmented flow.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model overall structure figure.
In figure: water source 1, water supply line 2, water supply branch road 3, service valve 4, heavy caliber reducing valve 5, No. two service valves 6, No. two water supply branch roads 7, No. three service valves 8, small-bore reducing valve 9, No. four service valves 10, user pipe 11, user's water valves 12.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, a kind of decompression water supply installation meeting different flow needs, it comprises water source 1, water source 1 is connected with water supply line 2, a water supply branch road 3 and No. two water supply branch roads 7 are parallel with after water supply line 2, be provided with heavy caliber reducing valve 5 after a described water supply branch road 3 being provided with a service valve 4, service valve 4, after heavy caliber reducing valve 5, be provided with No. two service valves 6.
Further, be provided with small-bore reducing valve 9 after described No. two water supply branch roads 7 being provided with No. three service valves 8, No. three service valves 8, after small-bore reducing valve 9, be provided with No. four service valves 10.
Further, described No. two service valves 6 are connected with user pipe 11 with No. four service valves 10 simultaneously, and user pipe 11 is connected with user's water valve 12.
Further, by adopting the parallel connection between heavy caliber reducing valve 5 and small-bore reducing valve 9, the decompression that can meet system during the demand of different output is supplied water.
Further, by arranging a service valve 4, No. two service valves 6, No. three service valves 8 and No. four service valves 10 conveniently when depressurized system breaks down, can carry out the upkeep operation of system in depressurized system in parallel.
Further, the bore of described small-bore reducing valve 9 is 1/3 of heavy caliber reducing valve 5 bore.The current of not flow can be provided by the reducing valve of different bore, thus meet the water requirements of different flow, also can select different relative apertures according to working environment.
Further, the rear set-pressure height 0.05MPa of set-pressure larger caliber reducing valve 5 after described small-bore reducing valve 9.Different pressure of supply waters can be realized by different rear set-pressures.
Operating principle of the present utility model is:
By adopting adjustable compression release valve reducing depressurized system in parallel on original pressure reducing circuit, select the heavy caliber reducing valve 5 of two different bores in parallel and small-bore reducing valve 9 simultaneously for user provides decompression water system, due to set-pressure height 0.05MPa after set-pressure larger caliber reducing valve 5 after small-bore reducing valve 9.When flow is less due to the difference of set-pressure after heavy caliber reducing valve 5 and small-bore reducing valve 9, heavy caliber reducing valve 5 cuts out, and small-bore reducing valve 9 is opened, thus carries out low discharge water supply; When user pipe after valve 11 flow increases, small-bore reducing valve 9 resistance increases, and when head pressure loss is equivalent to 0.05MPa, heavy caliber reducing valve 5 is opened, and now heavy caliber reducing valve 5 and small-bore reducing valve 9 work simultaneously, augmented flow.
Adopt adjustable compression release valve reducing in parallel, both having ensured the safety of system, and saved equipment investment, the Noise and vibration of low discharge by producing during heavy caliber reducing valve can being avoided again.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
