Background technique
When softened water supplies water, it is sometimes desirable to it samples softened water and is chemically examined, when there is more water pump parallel pumpings, general meeting
There are one or two reserve pumps, if directly being sampled after certain water pump, if the just pump does not start when sampling, the water of sampling
Sample is not the water sample of now thereof, sample examination inaccuracy.Moreover, if some with water spot only one or it is less, and use water spot
Just without using water, water pump does not start, and sampling water is the water that pipeline more early accumulates, and sample examination will inaccuracy.
Utility model content
The utility model provides a kind of constant pressure that can guarantee efficient sampling to solve shortcoming in the prior art
For water-sampling device.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of constant pressure water supply sampler, packet
It includes and softened water in softening water tank is fed into aqueduct with water spot, the aqueduct successively includes upstream tube by water (flow) direction
Road, middle reaches pipeline group and downstream line, middle reaches pipeline group are formed by more in the branch pipe(tube) being arranged in parallel, and each branch pipe(tube) connects
Upstream line and downstream line are connect, and is correspondingly provided with control valve and water pump on branch pipe(tube)；Downstream line is equipped with pressure sensing
Device, and the upstream end in downstream line positioned at pressure sensor is connected with sampling pipe.
The control valve being correspondingly arranged on each branch pipe(tube) includes the shut-off valve for being located at water pump upstream and downstream, and is located at water
Pump and the downstream check-valves between shut-off valve.
The middle reaches pipeline group is formed by three in the branch pipe(tube) being arranged in parallel.
Sampling valve is equipped on the sampling pipe, and the exit of sampling pipe is equipped with sink.
Motor-driven valve is equipped with positioned at the downstream of pressure sensor in the downstream line.
The utility model has the beneficial effects that
The utility model by downstream line be located at pressure sensor upstream end connect sampling pipe, so as to
Sample tap is formed on more water supply pump outfall sewers (i.e. downstream line), as long as having a water pump starting operation, sampling water in this way
It will be newest flowing water, result of laboratory test can really reflect water quality situation, and pressure sensing is equipped in downstream line
Device, after so that water pump constant pressure water supply, such sampling pipe is flowed out a part of water, downstream line pressure reduction, pressure sensor is issued
Signal feed pump, water pump starting operation, at this moment sampling water chemical examination is with regard to reflection water quality situation in time, so as to guarantee effectively to take
Sample.
Detailed description of the invention
Fig. 1 is the systematic schematic diagram of the utility model.
Specific embodiment
Arrow direction in Fig. 1 indicates the water (flow) direction in the utility model.
As shown in Figure 1, a kind of constant pressure water supply sampler of the utility model, including softened water in softening water tank 1 is supplied
To the aqueduct with water spot 27, the aqueduct successively includes upstream line 2, middle reaches pipeline group and downstream by water (flow) direction
Pipeline 23, middle reaches pipeline group are formed by more in the branch pipe(tube) being arranged in parallel, and each branch pipe(tube) is all connected with upstream line 2 and downstream
Pipeline 23, and control valve and water pump are correspondingly provided on branch pipe(tube).Pressure is disposed with by water flow trend in downstream line 23
Sensor 24, shut-off valve 25 and motor-driven valve 26, and the upstream end in downstream line 23 positioned at pressure sensor 24 is connected with sampling
Pipeline 19, is equipped with sampling valve 20 on sampling pipe 19, and the outlet of sampling pipe 19 is as water inlet 21, and in water inlet
Sink 22 is equipped at lower section.
In the present embodiment, the middle reaches pipeline group is formed by three in the branch pipe(tube) 7,12,17 being arranged in parallel, and is flowed away by water
To shut-off valve 3, water pump 4, check-valves 5 and shut-off valve 6 is disposed on branch pipe(tube) 7, moved towards on branch pipe(tube) 12 by water flow
It is disposed with shut-off valve 8, water pump 9, check-valves 10 and shut-off valve 11, is disposed with and cuts on branch pipe(tube) 17 by water flow trend
Only valve 31, water pump 14, check-valves 15 and shut-off valve 16.
When utility model works, the water of softening water tank 1, respectively can three pumps through branch pipe(tube) after upstream line 2
Group enters after main pipeline 23 for water spot water, and three pump groups can also can be started simultaneously with one group of starting with two groups or three groups.Cause
This, water in upstream line 2 respectively can be through branch pipe(tube) 7, and followed by the shut-off valve of pump group 3, water pump 4, check-valves 5, branch
Pipeline 7 enters downstream line 23；Can also through branch pipe(tube) 12, and followed by the shut-off valve of pump group 8, water pump 9, check-valves 10,
Shut-off valve 11 enters downstream line 23, can also be through branch pipe(tube) 17, and followed by the shut-off valve of pump group 13, water pump 14, non-return
Valve 15, shut-off valve 16 enter downstream line 23, and the water of downstream line 23 is used through shut-off valve 25, motor-driven valve 26 for water spot 27 again
Water.
Pressure sensor 24 is installed in downstream line 23, water pump constant pressure water supply may be implemented, is i.e. holding downstream line 23
Inside remain certain pressure.When with water spot water, motor-driven valve 26 is opened, and has water flowing in downstream line 23, at this moment can be with
Sampled pipeline 19 is from 21 sample examination of water inlet, and institute's water sampling is the water sample just flowed out from production wetting system.When with water spot not
When needing water, motor-driven valve 26 is closed, and keeps certain pressure water pump 4, water pump 9, water pump 14 out of service in downstream line 23.If taking
The shut-off valve 20 of sample pipeline 19 is opened, pressure reduction in downstream line 23, certain water pump starting, after flowing a period of time, sampling
Water is fetched water from water inlet 21 to vessel through pipeline 19, and sampling at this time is also to produce the new water sample flowed out in wetting system, rather than manage
The water accumulated in road, is then chemically examined, therefore, which can get fresh water sample.Sample water-saving mouth
Sink 22 is installed in 21 lower parts, prevents powder-refining with water when sampling from splashing ground.
The utility model by downstream line be located at pressure sensor upstream end connect sampling pipe, so as to
Sample tap is formed on more water supply pump outfall sewers (i.e. downstream line 23), as long as having a water pump starting operation, sampling in this way
Water will be newest flowing water, and result of laboratory test can really reflect water quality situation, and be equipped with pressure in downstream line 23
Sensor 24, after so that water pump constant pressure water supply, such sampling pipe is flowed out a part of water, 23 pressure reduction of downstream line, pressure is passed
Sensor 24 send a signal to water pump 4,9 and or 14, water pump starting operation, at this moment sampling water chemical examination just in time reflection water quality situation,
So as to guarantee efficient sampling.
Above embodiments are only to illustrate rather than limit the technical solution of the utility model, although referring to above-described embodiment pair
The utility model is described in detail, those skilled in the art should understand that: still can to the utility model into
Row modification or equivalent replacement should all without departing from any modification or partial replacement of the spirit and scope of the utility model
Cover in the scope of the claims of the utility model.
