Specific embodiment
Below by way of specific specific example and the embodiments of the present invention is described with reference to the drawings, those skilled in the art
Member can be understood easily the further advantage and effect of the utility model by content disclosed in the present specification.The utility model also may be used
It is implemented or is applied by other different specific examples, the various details in this specification can also be based on different viewpoints and answer
With, carried out under the spirit without departing substantially from the utility model it is various modification and change.
Fig. 1 is a kind of structural schematic diagram of water supply line biological film sampling apparatus of the utility model, and Fig. 2 is the utility model
The structural schematic diagram of biomembrane sampling head in specific embodiment, Fig. 3 are water supply line biology in the utility model specific embodiment
The actual installation structure chart of film sampler.As shown in Figure 1 to Figure 3, a kind of water supply line biomembrane sampling dress of the utility model
Set, used for being mounted in secondary water-supply pipeline, comprising: device main leg 1, biomembrane sampling head 2, discharge tap 3 with
And connecting flange 7, wherein device main leg 1 is equipped with multiple apertures, to be used to dispose multiple biomembrane sampling heads 2 respectively, at this
In utility model specific embodiment, the multiple apertures being arranged on device main leg 1 are internal screw thread aperture, and biomembrane sampling head 2 is
External screw thread design, is disposed with cooperating with the internal screw thread aperture of device main leg 1, and generally, multiple biomembrane sampling heads 2 can be for not
With the biomembrane sampling head of material, to dispose for researching and analysing influence of the unlike material tubing to biofilm formation and growth
Afterwards, the sampling section of biomembrane sampling head 2 is bonded with 1 inner tube surface of main leg, and discharge tap 3 is set to 1 end of device main leg
Downside discharge overpressure, prevent when taking out biomembrane sampling head 2, pipe internal pressure for the water of emptier main leg 1
Power is excessive and disrupting biofilm sampling head 2 samples the biomembrane on section, and connecting flange 7 is set to the both ends of device main leg 1,
The connecting flange 7 at both ends is connected with practical pipeline bypass pipe, for water supply line biological film sampling apparatus to be fixedly mounted.
In the utility model specific embodiment, device main leg 1 selects nominal bore for DN100, but the utility model
It is not limited, generally, if nominal bore is too small, can accordingly reduce the Sampling Area of biomembrane sampling head, if nominal bore
It is excessive, then it is unfavorable for in-site installation.It can be stainless steel, pvc, PE etc. that biomembrane sampling head 2, which selects material, can realistic simulation it is different
The sampling section of influence of the material tubing to biofilm formation and growth, biomembrane sampling head 2 is set as diameter 2.5cm or so,
But the utility model is not limited, and generally, if sampling section is excessive, section and main pipeline inner wall compactness are smaller, if taking
Sample section is too small, then can correspondingly reduce the collection capacity of biomembrane.Raw material band should be wound at the external screw thread of biomembrane sampling head 2,
Prevent leak.
As shown in figure 3, when the utility model is used, realizing water supply line by bypass pipe 5, valve 6 and connecting flange 7
Biological film sampling apparatus is in parallel with practical water supply line 4.Front and back valve 6 is opened, so that water supply line biological film sampling apparatus
Inside also there is water flow to pass through, guarantees that the water body in sampler main leg is identical as practical water body.Pass through the water supply of the utility model
When pipeline biofilm sampling device acquires biomembrane, front and back valve 6 need to be first closed, so that biological film sampling apparatus main leg 1
Interior no water body flow slowly unscrews discharge tap 3 and keeps the small flow outflow of water body, avoids water flow is excessive biomembrane is caused to take
The section biofilm detachment of sample head 2.Until flowing out in tap without water body, so far manifold pressure is down to 1 atmospheric pressure；Slowly
Unscrew biomembrane sampling head 2, it is seen that biomembrane has been attached on the sampling section of biomembrane sampling head 2, with tool by biomembrane
It scrapes and saves, for the detection and analysis of subsequent bio film, wound after again cleaning biomembrane sampling head 2 with raw material band
Afterwards, it tightens and is placed on sampler main leg 1, so that the inner tube surface fitting in the sampling section of sampling head 2 and main leg 1, beats
Front and back valve 6 on card bypass pipe 5, when discharge tap 3 has continuous water body outflow (biological film sampling apparatus main leg at this time
Without air in 1) when, close discharge tap 3.So far, start the water supply line biology Membrance cuiture and sampling work of a new round.
The water supply line biological film sampling apparatus of the utility model, is installed in parallel in practical water supply line, in subsequent life
In object film sampling process, the normal water supply of practical water supply line is not influenced.Further, since water supply quality is identical, therefore taken
It is consistent in biomembrane and practical pipeline, there is the representativeness of research.The water supply line biological film sampling apparatus of the utility model, can
To realize the multiple sampling of pipeline biomembrane, while the biological film sampling apparatus can be installed by replacement biomembrane sampling head
The biomembrane sampling head of unlike material, for researching and analysing influence of the unlike material tubing to biofilm formation and growth and can
To set up multiple sample taps in same position, for researching and analysing influence of the different incubation times to biofilm formation and growth.
The water supply line biological film sampling apparatus structure of the utility model is simple, easy to operate, and repeatability is strong, closes before and after main leg
Valve opens discharge tap and waits for that device main leg's non-water flow flows out, can turn and take out biomembrane sampling head, and is mountable
New biomembrane sampling head carries out the work for continuing acquisition, without intercepting practical water supply line, can be achieved with the multiple of biomembrane
The problems such as sampling, can largely save time, cost of labor etc., avoid practical water supply line interception difficulty big.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Anyone skilled in the art can repair above-described embodiment under the spirit and scope without prejudice to the utility model
Decorations and change.Therefore, the rights protection scope of the utility model, should be as listed in the claims.
