Description
Technical field
The utility model relates to water quality detection instrument water fetching device field, specifically the controlled water fetching device of a kind of detecting instrument.
Background technology
the instrument of current waterworks to water quality detection is varied, such as heavy metal detector, turbidimeter etc.Need to sample to the tap water at scene in testing process, this sampling process must keep the flowing of water sample, can get fresh water sample sample, ensure that the real-time of instrument in testing process.Current water fetching device is divided into two kinds of situations: one is for the water surface lower than ground, and this situation adopts water pump by the water pump be located in usually to exceeding through detecting instrument sampling in eliminating.Two is the samplings for there being hydraulic pressure, and this situation needs to have the water sample of hydraulic pressure to become water sample without hydraulic pressure, and this process need water-storing device reduces pressure.Both of these case can meet the sampling demand of detecting instrument, but for field condition complex installation process, need to formulate water extracting scheme according to site environment, dirigibility reduces, sampling in addition for detecting instrument is just carried out in section sometime, thus above-mentioned two schemes all cannot accomplish real-time monitoring, causes the loss of equipment and the waste of resource.
utility model contentthe purpose of this utility model is to provide the controlled water fetching device of a kind of detecting instrument, to solve prior art Problems existing.
In order to achieve the above object, the technical scheme that the utility model adopts is:
The controlled water fetching device of a kind of detecting instrument, include housing, it is characterized in that: housing side sidewall is provided with instrument injection port, first water inlet sample mouth, second water inlet sample mouth, housing opposite side sidewall is provided with backwater sample mouth, described instrument injection port is serially connected with the first three-way interface successively by pipeline in housing, second three-way interface, 3rd three-way interface, first water inlet sample mouth passes through the first water sample filtrator successively in housing, first ball valve is communicated with the second three-way interface, second water inlet sample mouth passes through the second water sample filtrator successively in housing, water pump, second ball valve is communicated with the 3rd three-way interface, described first three-way interface to be also communicated with backwater sample mouth by pipeline and to form overflow pipe, and between the first three-way interface and backwater sample mouth, pipeline is provided with the 4th three-way interface, described 3rd three-way interface also passes through solenoid valve successively, 4th three-way interface is communicated with backwater sample mouth.
The described controlled water fetching device of a kind of detecting instrument, is characterized in that: be also provided with the controller be connected with solenoid valve, water pump respectively in described housing.
Advantage of the present utility model:
The utility model apparatus structure is simple, can meet the sampling of multiple-quality water detecting instrument, and can provide low-water level and have hydraulic pressure to sample two kinds of modes.This device can receive the control of detecting instrument, stops sampling need not causing the waste of resource and the loss of equipment when not needing to detect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Figure 1, the controlled water fetching device of a kind of detecting instrument, include housing, housing side sidewall is provided with instrument injection port 2, first water inlet sample mouth 3, second water inlet sample mouth 4, housing opposite side sidewall is provided with backwater sample mouth 5, instrument injection port 2 is serially connected with the first three-way interface T1 successively by pipeline in housing, second three-way interface T2, 3rd three-way interface T3, first water inlet sample mouth 3 passes through the first water sample filtrator L1 successively in housing, first ball valve K1 is communicated with the second three-way interface T2, second water inlet sample mouth 4 passes through the second water sample filtrator L2 successively in housing, water pump M, second ball valve K2 is communicated with the 3rd three-way interface T3, first three-way interface T1 to be also communicated with backwater sample mouth 5 by pipeline and to form overflow pipe, and between the first three-way interface T1 and backwater sample mouth 5, pipeline is provided with the 4th three-way interface T4, 3rd three-way interface T3 is also successively by solenoid valve K3, 4th three-way interface T4 is communicated with backwater sample mouth 5.The controller 1 be connected with solenoid valve K3, water pump M respectively is also provided with in housing
The utility model includes controller 1, instrument injection port 2, first water inlet sample mouth 3, second water inlet sample mouth 4, backwater sample mouth 5, first water sample filtrator L1, second water sample filtrator L2, first three-way interface T1, second three-way interface T2, 3rd three-way interface T3, 4th three-way interface T4, first ball valve K1, second ball valve K2, solenoid valve K3 and water pump M, device provides the water-supply method of two kinds of situations, low liquid level water intaking: external pipe connects water inlet sample mouth 4, internal pipeline connects the second water sample filtrator L2 successively, water pump M and the second ball valve K2, eventually pass through the 3rd three-way interface T3 to be connected with intermediate reservoirs.Hydraulic pressure is had to fetch water: external pipe connects the first water inlet sample mouth 3, and internal pipeline connects the first water sample filtrator L1 successively, the first ball valve K1 is connected with intermediate reservoirs through the second three-way interface T2 again.Cistern top forms overflow pipe by the first three-way interface T1 and backwater sample mouth 5, and cistern bottom connected electromagnetic valve K3 is connected with backwater sample mouth 5 through the 4th three-way interface T4.
Water level is lower than surface water intaking sample: by water pump M, the water sample of lower is pumped into intermediate reservoirs from water inlet sample mouth 4, water sample removes the solid impurity in water through the second water sample filtrator L2, by regulating the switch size of the second ball valve K2 to keep spilling water amount equal with inflow, detecting instrument is sampled by instrument injection port 2.There is hydraulic pressure water sampling: have the water pipe of hydraulic pressure to access water inlet sample mouth 3 and enter intermediate reservoirs by the first water sample filtrator L1 through the first ball valve K1, regulate the switch size of the first ball valve K1 to keep spilling water amount equal with inflow, detecting instrument is sampled by instrument injection port 1.Controller 1 controls the opening and closing of water pump, and when using water pump, detecting instrument sends instruction controls water sampling carrying out to controller.Controller 1 also controls the water sample in the next emptying cistern of solenoid valve K3 of intermediate reservoirs bottom simultaneously.
