Description

Check-valves water circuit system is opened in rubber clack rotation
Technical field
Water supply and drainage pipe technology field is the utility model is related to, more particularly to check-valves water route system is opened in a kind of rotation of rubber clack System.
Background technology
Traditional water plant pumps out intake check valve misuse multifunctional water pump control valve and simulates national standard atlas 04S204《Fire-fighting Special water pump is selected and installation》Wrong method, a bay window rubber soft joint is designed on pumping water transverse tube, this Air bag can be produced on kind joint construction, specification, handbook and textbook requirement is not met, greatly reduces pumping water efficiency, by mistake It is also incorrect with multifunctional water pump control valve, because changing the very tender and lovely sensitivity of the subsidiary needle-valve of valve, when source quality turbidity is more than 3 When spending, easily malfunction, therefore the muddy water plant in summer water source is also cannot be used in, when control valve exit static pressure and import are quiet Pressure is when being less than 5m, the technical measures that should be set high-order extra feed tank or take other to increase valve export and import static pressure difference.Stop Filtering ponds group water level is extremely difficult to more than 5m with mouth piece elevation difference during pump.
In view of it is above-mentioned the defects of, the design people is actively subject to research and innovation, and non-return is opened to found a kind of rotation of rubber clack Valve water circuit system, make it with more the value in industry.
Utility model content
In order to solve the above technical problems, the purpose of this utility model, which is to provide a kind of rubber clack rotation, opens check-valves water route system System, avoid producing air bag, securely and reliably, ensure that feedwater is normal.
Check-valves water circuit system is opened in a kind of rotation of rubber clack of the utility model, including two water inlet pipes, is arranged on water inlet pipe end The horn mouth at end, the first water pump being connected on water inlet pipe and the second water pump, in two water inlet pipe current intersection Provided with standpipe, the water outlet end of the first water pump is provided with two water outlet branch roads, and tie point is provided with rubber clack rotation and opens check-valves, Second branch road is provided with drain valve;Two water outlet branch roads are again provided with the second pump outlet end, in tie point Check-valves is opened provided with rubber clack rotation, the second branch road is provided with drain valve;The standpipe is provided with Power Hi-speed;Described first The inlet end of water pump and the second water pump is connected with steel expansion joint.
Further, the inlet end of first water pump and the second water pump is provided with gate valve.
Further, the drain valve is provided with internal thread, specification DN25.
Further, the specification of the Power Hi-speed is DN50~DN150.
Further, it is respectively equipped with air intake duct on described two water inlet pipes.
By such scheme, the utility model at least has advantages below:1st, this practical technique is in 02S403 copper pipes Steel expansion joint is changed on the basis of part national standard atlas, at pump intake to be arranged on water pump water suction transverse tube, can It is flexible to avoid producing air bag again;On water pump outlet pipe, then it is changed to rubber clack rotation and opens and (be commonly called as waving) formula check-valves, such a non-return The not subsidiary tender and lovely needle-valve of valve, unrelated with more muddy source quality, summer can overcome the influence of the current containing silt, just normally opened Open and close, it opens and closes resistance and head very little, and many engineering practices verify that this inventive technique is simple and practical.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is that check-valves water circuit system structural representation is opened in the rotation of the utility model rubber clack.
In figure:1st, the first water pump, the 2, second water pump, 3, rubber clack rotation open check-valves, 4, drain valve, 5, air intake duct, 6, row Air valve, 7, gate valve, 8, horn mouth.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail, below Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Embodiment 1
Referring to Fig. 1, operation principle of the present utility model is as follows:Check-valves water circuit system, including two are opened in a kind of rubber clack rotation Root water inlet pipe, the first water pump 1 and the second water pump 2 for being arranged on the horn mouth 8 into water pipe end, being connected on water inlet pipe, Standpipe is provided with two water inlet pipe current intersection, the water outlet end of the first water pump 1 is provided with two water outlet branch roads, and first Branch road is provided with rubber clack rotation and opens check-valves 3, and the second branch road is provided with drain valve 4;It is same on the water outlet end of the second water pump 2 Sample is provided with two water outlet branch roads, and tie point is provided with rubber clack rotation and opens check-valves 3, and the second branch road is provided with drain valve 4;It is described Standpipe is provided with Power Hi-speed 6;The inlet end of the water pump 2 of first water pump 1 and second is connected with steel expansion joint.
The inlet end of first water pump 1 and the second water pump 2 is provided with gate valve 7, and drain valve 4 is provided with internal thread, specification DN25, The specification of Power Hi-speed 6 is DN50, and air intake duct 5 is respectively equipped with two water inlet pipes.
First water pump is stopped, and standby second water pump opens a moment temporarily, opens internal thread DN25 drain valves, checks rubber The rotation of glue valve opens whether check-valves is working properly, and check-valves is opened in replacing rubber clack rotation in time of pinpointing the problems, and closes drain valve, the second water Pump is out of service, and water suction horn mouth stretches into the big water suction hole of clear water reserviors or absorbing well, absorption well.Clean water is delivered to clear water reserviors, sub warhead It is not very high that DRV about opens check-valves high 12% than rubber clack rotation, but its fatal flaw is that low-lift pump is extremely difficult when starting 100% it is fully open, cause two one-tenth to open the multiplication of eighty per cant closed state resistance and weaken flow, water pump suction inlet is eccentric and water pumps out Mouth concentric reducer does not draw, higher than the major part center absolute altitude of eccentric reducer with one heart, water pump suction outlet gate valve and water water pump The expansion joint of suction inlet steel and exit of pump connecting hose are all located at major part side.
Embodiment 2
The specification of Power Hi-speed 6 is DN150, and the Power Hi-speed that comparative example 1 chooses high standard can be more Good exhaust, ensure that system operation is smooth, adapt to big yield operation.
Embodiment 3
The specification of Power Hi-speed 6 is DN100, and the Examples 1 and 2 of description are said in contrast above, chooses the height of the specification Fast air inlet and exhaust valve goes for medium water level's operation, ensure that the security of system, it is possible to reduce the loss of water.
Described above is only preferred embodiment of the present utility model, is not limited to the utility model, it is noted that For those skilled in the art, on the premise of the utility model technical principle is not departed from, can also do Go out some improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
