Abstract

The utility model discloses a water sampler for detecting dissolved oxygen. The water sampler comprises a dissolved oxygen sensor and a cleaner, wherein the cleaner is provided with a circulating pump; a pipe sleeve is arranged above the cleaner; the dissolved oxygen sensor is arranged in the pipe sleeve and is connected with a water outlet of the cleaner; a filter screen is arranged at the water inlet of the cleaner; and a filter cover is arranged between the filter screen and a water inlet. The water sampler presses and fixes the dissolved oxygen sensor through the pipe sleeve and a pressing cover, so that the dissolved oxygen sensor is prevented from damage caused by rotating, transverse pressing and the like. As the filter cover is additionally adopted, and the assembling structure of the circulating pump is changed, the clearance between the circulating pump and the filter screen is greatly increased, and the water circulating effect is improved; simultaneously, the deposited dirt in the cleaner is reduced, and the maintenance period of the dissolved oxygen sensor is greatly prolonged.

Description

Be used for the water sampler that dissolved oxygen detects
Technical field
The utility model relates to a kind of water sampler, is specifically related to a kind of water sampler that dissolved oxygen detects that is used for.
Background technology
The existing water sampler that is used for the dissolved oxygen detection comprises dissolved oxygen sensor, the washer of ebullator is installed, dissolved oxygen sensor is to fix by the screw thread of low side, constitute a kind of loop structure with ebullator and washer then, dissolved oxygen sensor can be worked under certain water velocity.The shortcoming of this structure is: directly add screw thread, can be rotated operation to dissolved oxygen sensor during use at the dissolved oxygen sensor low side, when dissolved oxygen sensor when repeatedly mounting or dismounting are used, the screw thread explosion can appear, connecting line revolves bad phenomenon such as disconnected.In addition, ebullator in this method all is to be contained in the washer shell, only add a screen pack on the pump surface, such way assembling is simple, but run into easy obstruction when in use, clean difficult problem, need clean continually, increase the maintenance difficulties of dissolved oxygen sensor greatly.
Summary of the invention
Problem to be solved in the utility model is at the deficiency of above-mentioned technology, to design the water sampler that a kind of result of use is good, maintenance period long, easy-on is used for the dissolved oxygen detection.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of water sampler that is used for the dissolved oxygen detection, comprise dissolved oxygen sensor and the washer that ebullator is installed, the top of described washer is provided with pipe box, dissolved oxygen sensor is installed in the pipe box and with the water delivering orifice of washer and is connected, the water inlet of washer is provided with screen pack, is provided with filter mantle between screen pack and the water inlet.
Such scheme also has following improvement project: described dissolved oxygen sensor is pressed in the pipe box by gland; Between described pipe box and the washer for being threaded; Described filter mantle and screen pack are installed on the washer by upper and lower filtration cover plate.
The beneficial effects of the utility model are: the utility model is fixed dissolved oxygen sensor by pipe box and gland, dissolved oxygen sensor can not occur again because rotation, the laterally damage that causes such as pressurized, simultaneously, owing to increased filter mantle, conversion the assembly structure of ebullator, the gap between ebullator and the screen pack is greatly improved, improved the effect of water cycle, reduced the deposition of dirt simultaneously, prolonged the maintenance period of dissolved oxygen sensor greatly in the washer the inside.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of result of use provided by the utility model is good, maintenance period long, easy-on is used for the water sampler that dissolved oxygen detects, comprise dissolved oxygen sensor 1 and the washer 2 that ebullator 3 is installed, the top of described washer 2 is provided with pipe box 4, dissolved oxygen sensor 1 is installed in the pipe box 4 and with the water delivering orifice 21 of washer 2 and is connected, water inlet 22 places of washer 2 are provided with screen pack 5, are provided with filter mantle 6 between screen pack 5 and the water inlet 22.
As preferred embodiment, dissolved oxygen sensor 1 is pressed in the pipe box 4 by gland 41, and dissolved oxygen sensor 1 is installed in the pipe box 4 tightly, thereby can not cause measuring error bigger than normal because of state such as occurring rocking.And between pipe box 4 and the washer 2 for being threaded, pipe box 4 can not caused damaging because of horizontal pressurized, further improve its serviceable life.Install for convenience, filter mantle 6 and screen pack 5 are installed on the washer 2 by upper and lower filtration cover plate 23,24, last filtration cover plate 23 is installed in water inlet 22 ends of washer 2 and is pressing ebullator 3, filters loam cake 23 and filter mantle 6 and filter mantle 6 and filter between the lower cover 24 to be screwed.The intensity height of whole like this water sampler is not easy to damage, and has prolonged its maintenance period greatly.
The above, it only is the utility model preferred embodiment, be not that the utility model is done restriction completely, every foundation technical spirit of the present utility model all belongs to the scope of technical solutions of the utility model to any simple modification, equivalent variations or decoration that above embodiment did.
