Abstract
The utility model discloses a correcting unit is shown to dissolved oxygen for water quality monitoring, dissolved oxygen table correcting unit be square flow -through cell hickey section, external seal circle recess section, observation section, canned paragraph and the base that is used for inserting the electrode that be equipped with in proper order from top to bottom, form an airtight appearance chamber between electrode and flow -through cell hickey section, external seal circle recess section, observation section, canned paragraph and the base, sodium hydrosulphite and cobaltous chloride be equipped with at airtight appearance intracavity. The utility model discloses dissolved oxygen table electrode passes through external seal circle recess section and the inside seal circle is realized and correcting unit's double containment, has ensured dissolved oxygen table electrode and correcting unit's zonulae occludens to be equipped with sodium hydrosulphite and cobaltous chloride in correcting unit's airtight appearance chamber and accomplish deoxidization and protection positive electrode, increase dissolved oxygen the sensing electrodes's life -span, improve its stability and accurate nature, reach the most genuine anaerobic state (zero point), rectify dissolved oxygen table zero point. Wherein the internal state can directly perceivedly be seen to the special material design of flow -through cell.
Description
Technical field
The utility model relates to a kind of means for correcting, and particularly a kind of water quality monitoring dissolved oxygen table means for correcting, belongs to purification technology field.
Background technology
The monitoring accurately and reliably of oligodynamical oxygen value in water, to the corrosion preventing boiler or other power-equipment, ensures that its safe operation has great significance, and being the important leverage of safety in production, is also the major issue that economize energy is benefited the nation and the people.At present, the measuring method of domestic and international trace dissolved oxygen mainly contains two kinds, and one is visual colorimetry, and another kind is trace quantity dissolved oxygen instrument determination method, and present measurement transfers the monitoring of measuring instrument substantially to from artificial colorimetric.Although oligodynamical oxygen measuring device is simple to operate, resolution is high, reproducible, and can be arranged on pipeline trace dissolved oxygen is carried out on-line measurement, monitored in real time, there is provided signal that is rapid, that continue, but in water, the accuracy of oligodynamical oxygen measuring device cannot ensure.In addition, domestic now to the important technology such as accuracy and the repeatability index of trace dissolved oxygen analyzer, there is no corresponding detection means, cannot examine and determine it.
Utility model content
The utility model object provides a kind of water quality monitoring dissolved oxygen table means for correcting to overcome the deficiencies in the prior art, the dissolved oxygen table means for correcting of the calibration function of manpower burden and error can be reduced, produce because tradition there is no automatic calibration in order to the dissolved oxygen table measuring dissolved oxygen in water, also can increase the life-span of dissolved oxygen sensing electrode.
Technical solution of the present utility model is achieved in that water quality monitoring dissolved oxygen table means for correcting, and described dissolved oxygen table means for correcting from top to bottom side is provided with flow cell hickey section, exterior seal ring groove section, viewing section, canned paragraph and base for accessing electrode successively; Described electrode and flow cell hickey section, exterior seal ring groove section, viewing section, between canned paragraph and base, form a closed containing cavity; At described closed containing cavity built with sodium sulphite and cobalt chloride.
Improve further as the utility model, be provided with inner seal ring in described flow cell hickey section and electrode connection.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Water quality monitoring dissolved oxygen table means for correcting of the present utility model; dissolved oxygen table electrode realizes the dual seal with means for correcting by exterior seal ring groove section and inner seal ring; ensure that the compact siro spinning technology of dissolved oxygen table electrode and means for correcting; and at the closed containing cavity of means for correcting, sodium sulphite and cobalt chloride are housed and accomplish deoxygenation and protection positive electrode; the life-span of dissolved oxygen sensing electrode can be increased; improve its stability and degree of accuracy, reach anaerobic state (zero point) truly, correct dissolved oxygen table zero point; Wherein the design of viewing section intuitively can see circulation status.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of water quality monitoring dissolved oxygen table means for correcting of the present utility model;
Accompanying drawing 2 is that the A-A of water quality monitoring dissolved oxygen table means for correcting of the present utility model is to structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
Be water quality monitoring dissolved oxygen table means for correcting as shown in Figure 1, described dissolved oxygen table means for correcting from top to bottom side is provided with flow cell hickey section 1, exterior seal ring groove section 2, viewing section 3, canned paragraph 4 and base 5 for accessing electrode successively; Described electrode and flow cell hickey section 1, exterior seal ring groove section 2, viewing section 3, between canned paragraph 4 and base 5, form a closed containing cavity 6; At described closed containing cavity 6 built with sodium sulphite 7 and cobalt chloride 8.
As shown in Figure 2, inner seal ring 9 is provided with in described flow cell hickey section 1 with electrode connection.
Water quality monitoring dissolved oxygen table means for correcting of the present utility model, by flow cell hickey section 1 and Electrode connection, adopt exterior seal ring groove section 2 again and at junction inner seal ring 9, realize dual seal, totally-enclosed sealing ensure that the compact siro spinning technology of dissolved oxygen table electrode and means for correcting, guarantee to enter without air, improve its stability and degree of accuracy; And at the closed containing cavity 6 of means for correcting, sodium sulphite 7 and cobalt chloride 8 are housed and accomplish deoxygenation and protection positive electrode; the life-span of dissolved oxygen sensing electrode can be increased; reach anaerobic state (zero point) truly; automatic calibration dissolved oxygen table zero point; wherein the design of viewing section intuitively can see circulation status; guarantee to detect the accurate of data, guarantee to detect the accurate of data.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
Claims (2)
1. water quality monitoring dissolved oxygen table means for correcting, is characterized in that: described dissolved oxygen table means for correcting from top to bottom side is provided with flow cell hickey section, exterior seal ring groove section, viewing section, canned paragraph and base for accessing electrode successively; Described electrode and flow cell hickey section, exterior seal ring groove section, viewing section, between canned paragraph and base, form a closed containing cavity; At described closed containing cavity built with sodium sulphite and cobalt chloride.
