Description

Dew point generator

Technical field

This utility model is related to dew point hygrometer collimation technique field, especially a kind of dew point generator.

Background technology

Dew point hygrometer and moisture monitor are the instruments detecting water content in all kinds of gases, and they are in electric power, petrochemical industry, natural Numerous industry such as gas, iron and steel, microelectronics plays an important role, especially ensure all kinds of generating equipments (nuclear power, thermoelectricity) and The aspects such as the safe operation of power transmission and transforming equipment, the safe handling ensureing petrochemical equipment and energy-saving and emission-reduction play pivotal role.

The assay calibration of all kinds of dew point hygrometers is required for using humidity generator, is usually used in dew point (humidity) calibrating or calibrates The equipment in field has double pressure humidity generators, shunting humidity generator, osmosis humidity generator, and these device structures are multiple Miscellaneous, use and operation requires that comparison is high；Therefore be accomplished by designing a kind of can structure relatively easy, dew point easy and simple to handle occurs Device.

Utility model content

This utility model aim to provide a kind of automatically controlled according to the dew point setting value of user by dew point control module defeated Go out the dampness of corresponding dew point, dampness output pipe automatic constant-temperature prevents from condensing, the dew point generator of adjusting output flow.

For achieving the above object, this utility model provides following technical scheme: dew point generator, including dew point system System, there is system by dew point generating meanss, dew point control module, output pipe thermostat module and Flow-rate adjustment valve group in described dew point Become, wherein dew point generating meanss are positioned in ethanol temperature chamber, this dew point generating means passes through automatic dehumidifying filter and connects no Oil pressure pump, the outlet of dew point generating meanss connects dampness output pipe, and this dampness output pipe is sequentially installed with outlet tube Road thermostat module and flow control valve；Dew point generating meanss are also connected with dew point control module.

As further scheme of the present utility model: described no oil pressure pump connects source of the gas.

As further scheme of the present utility model: be provided with excess temperature overvoltage protective module in this dew point generator.

Compared with prior art, the beneficial effects of the utility model are: this dew point generator passes through dew point control module root Automatically control the dampness exporting corresponding dew point according to the dew point setting value of user, dampness output pipe automatic constant-temperature prevents from condensing, can Adjust output flow.

This dew point generator can arbitrary continuation occur -70 DEG C～40 DEG C of dew points dampness, flow 0～5l/min is adjustable, whole Individual compact equipment, compact, high degree of automation simultaneously, equipment automatic constant-temperature automatically controls, and carries excess temperature overvoltage to protect Shield, is worth promoting.

Brief description

Fig. 1 is workflow schematic diagram of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Refer to Fig. 1, in this utility model embodiment, dew point generator, there is system including dew point, described dew point occurs System is made up of dew point generating meanss 1, dew point control module 2, output pipe thermostat module 3 and flow control valve 4, wherein dew point Generating meanss 1 are positioned in ethanol temperature chamber 10, and this dew point generating means 1 connects no oil pressure by automatic dehumidifying filter 5 Pump 6, the outlet of dew point generating meanss 1 connects dampness output pipe, this dampness output pipe is sequentially installed with output pipe permanent Warm module 3 and flow control valve 4；Dew point generating meanss 1 are also connected with dew point control module 2, by dew point control module 2 according to The dew point setting value at family automatically controls the dampness exporting corresponding dew point.

Further, it is provided with excess temperature overvoltage protective module in this dew point generator.

Operation principle of the present utility model: after dew point generating meanss 1 air inlet is by no oil pressure pump 6 reduces pressure, then by automatically Dehumidifying filter 5 enters dew point generating meanss 1 after being dried；Dew point generating meanss 1 are positioned in ethanol temperature chamber 10, by dew point control Molding block 2 automatically controls the dampness exporting corresponding dew point according to the dew point setting value of user；Dampness output pipe automatic constant-temperature is prevented Only condense, adjusting output flow.

This dew point generator can arbitrary continuation occur -70 DEG C～40 DEG C of dew points dampness, flow 0～5l/min is adjustable, whole Individual compact equipment, compact.High degree of automation simultaneously, equipment automatic constant-temperature automatically controls, and carries excess temperature overvoltage to protect Shield.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as limiting Involved claim.

Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment only wraps Containing an independent technical scheme, only for clarity, those skilled in the art should for this narrating mode of description Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined Understandable other embodiment.
