Description
Technical field
Check-valves water circuit system is opened the present invention relates to water supply and drainage pipe technology field, more particularly to a kind of rotation of rubber clack.
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 installed》Wrong method, designs a bay window rubber soft joint on pumping water transverse tube, this
Air bag can be produced on joint construction by planting, and do not met specification, handbook and textbook requirement, greatly reduced 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
When pressure is less than 5m, high-order extra feed tank should be set or take other to increase the technical measures of 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 above-mentioned defect, the design people is actively subject to research and innovation, and non-return is opened to found a kind of rubber clack rotation
Valve water circuit system, makes it with more the value in industry.
The content of the invention
In order to solve the above technical problems, opening check-valves water circuit system it is an object of the invention to provide a kind of rotation of rubber clack, keep away
Exempt to produce air bag, it is safe and reliable, it is ensured that feedwater is normal.
Check-valves water circuit system is opened in a kind of present invention rubber clack rotation, including two water inlet pipes, is arranged on into water pipe end
Horn mouth, the first water pump being connected on water inlet pipe and the second water pump, are provided with two water inlet pipe current intersection
Standpipe, the water outlet end of the first water pump is provided with two water outlet branch roads, and tie point opens check-valves, second provided with rubber clack rotation
Branch road is provided with drain valve；Two water outlet branch roads are again provided with the second pump outlet end, tie point is provided with
Check-valves is opened in rubber clack rotation, and the second branch road is provided with drain valve；The standpipe is provided with Power Hi-speed；First water pump
Steel expansion joint is connected with the inlet end of the second water pump.
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, and specification is 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 present invention at least has advantages below：1st, this practical technique is in 02S403 copper pipe fittings state
On the basis of family's standard collective drawingses, steel expansion joint is changed at pump intake and is arranged on water pump water suction transverse tube, both flexibles
It can 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 check-valves is not
Subsidiary tender and lovely needle-valve, unrelated with relatively muddy source quality, summer can overcome the influence of the current containing silt, it is normally-open with
Close, it opens and closes resistance and head very little, many engineering practice checkings, this inventive technique is simple and practical.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Brief description of the drawings
Fig. 1 is that check-valves water circuit system structural representation is opened in rubber clack rotation of the present invention.
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, the embodiment to the present invention is described in further detail, and is implemented below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Embodiment 1
Referring to Fig. 1, operation principle of the invention is as follows：Check-valves water circuit system is opened in a kind of rubber clack rotation, including two are entered
Water pipe, the first water pump 1 and the second water pump 2 for being arranged on horn mouth 8 into water pipe end, being connected on water inlet pipe, in institute
Two water inlet pipe current intersections are stated provided with standpipe, the water outlet end of the first water pump 1 is provided with two water outlet branch roads, tie point
Check-valves 3 is opened provided with rubber clack rotation, the second branch road is provided with drain valve 4；Equally set on the water outlet end of the second water pump 2
There are two water outlet branch roads, tie point opens check-valves 3 provided with rubber clack rotation, and the second branch road is provided with drain valve 4；The standpipe
It 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, and specification is DN25,
The specification of Power Hi-speed 6 is to be respectively equipped with air intake duct 5 on DN50, 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 is pumped out
Mouth concentric reducer does not draw, and the major part center absolute altitude than eccentric reducer is higher 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, it is ensured that system operation is smooth, adapts to big yield operation.
Embodiment 3
The specification of Power Hi-speed 6 is DN100, and contrast says the Examples 1 and 2 of description, chooses the height of the specification above
Fast air inlet and exhaust valve goes for medium water level's operation, it is ensured that the security of system, it is possible to reduce the loss of water.
Described above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and
Modification, these improvement and modification also should be regarded as protection scope of the present invention.
