Abstract
The embodiment of the utility model discloses a sampling jet pump, which comprises a casing body provided with a power source inlet, a second laval nozzle and a sample inlet, wherein a first laval nozzle arranged in the same direction with the second laval nozzle is disposed in a cavity inside the casing body, and a maintenance opening is also disposed on the casing body and sealed through bolts. The two laval nozzles arranged on the sampling jet pump are capable of performing acceleration twice on a power source of the sampling jet pump, thereby flow rate of the power source of the sampling jet pump is increased so as to increase suction force of the sampling jet pump. Accordingly, when pressure of an original analytic sample can not meet the requirement of an analytical instrument, the sampling jet pump is capable of leading the analytic sample to be sucked into the analytical instrument so that the same can perform normal analysis on the analytic sample. Additionally, the maintenance opening arranged on the sampling jet pump brings convenience for maintenance of the sampling jet pump and replacement of parts thereof.
Description
Technical field
The utility model relates to the gas analysis field, more particularly, relates to a kind of sampling Jet injector.
Background technique
At the technical analysis scene, often have analyzed sample strain and cross the low situation that can't satisfy the normal use of analytical instrument.At this moment, need improve the pressure and the flow of sample, with so that analyzed sample can enter analytical instrument with supercharging equipment.The general motor-drive pump that uses solves the problems referred to above in the prior art, but owing to analyze on-the-spot actual conditions, sample often has a large amount of solid-state or liquid impurities.When impurity solid-state when these or liquid impurities enters into motor-drive pump, can cause expendable damage to motor-drive pump.When using traditional Jet injector,, possibly can't make required analyzed sample enter analytical instrument because the suction force of traditional Jet injector is less.
The model utility content
In view of this, the utility model provides a kind of suction force big sampling Jet injector, also can normally enter analytical instrument when making the analytic sample hypotony, thereby analytical instrument can be analyzed normally to analytic sample.
For achieving the above object, the utility model provides following technological scheme:
A kind of sampling Jet injector comprises:
Be provided with the housing of power source inlet, second Laval nozzle and sample inlet;
Be provided with first Laval nozzle of an and equidirectional setting corresponding in the cavity in described housing with the described second Laval nozzle position;
Preferably, described housing also is provided with service port, and described service port uses bolt airtight.
From above-mentioned technological scheme as can be seen, the utility model embodiment has increased the suction force of sampling Jet injector by the scheme of two Laval nozzles is set simultaneously.Thereby make analytic sample pressure not reach under the needed situation of analytical instrument, increase the negative pressure of analytic sample.Make analytic sample normally enter analytical instrument, thereby analytical instrument can be analyzed normally to analytic sample.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the take a sample structural representation of Jet injector of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of sampling Jet injector, also can normally enter analytical instrument when being implemented in the analytic sample hypotony, thereby analytical instrument can be analyzed normally to analytic sample.
The utility model embodiment's sampling Jet injector can be widely used in the sample analysis system in various fields such as chemical industry, petrochemical industry, metallurgy, and power source can adopt water, oil, steam, pressurized air, other pressurized gas etc.
As shown in Figure 1, the utility model embodiment's sampling Jet injector comprises the housing 4 that is provided with power source inlet 1, second Laval nozzle 2 and sample inlet 3.Be provided with first Laval nozzle 6 of an and equidirectional setting corresponding in the cavity 5 in described housing 4 with described second Laval nozzle 2 positions.
Power source described in embodiment of the invention inlet 1 is located at the front end of described first Laval nozzle 5, can pass through the acceleration of described first Laval nozzle 6 like this after entering in the described cavity 5 as gas such as the water of power source, oil, steam, pressurized air, other pressurized gas or liquid.Because on described housing 4,, also be provided with and described first Laval nozzle, 6 equidirectional described second Laval nozzles 2 with the corresponding position of described first Laval nozzle 6.Make and further to be quickened when described second Laval nozzle 2 of ejection as gas such as the water of power source, oil, steam, pressurized air, other pressurized gas or liquid.Negative pressure according to Laval nozzle forms principle, the increase of the flow velocity when spraying described second Laval nozzle 2 as gas such as the water of power source, oil, steam, pressurized air, other pressurized gas or liquid can make the negative pressure of described sample inlet increase, thereby has improved the suction force of sampling Jet injector.
In another model utility embodiment, the described housing 4 among the above-mentioned model utility embodiment can also be provided with service port 7, and described service port 7 uses bolt airtight.In the utility model embodiment, at described housing 4 by being provided with service port 7, make parts in the described cavity 5 of sampling Jet injector of the present utility model when breaking down, when situations such as 6 damages of first Laval nozzle or fault take place as described, be used for airtight bolt by opening, can safeguard or change the damage parts easily.
In sum, the utility model embodiment is designed to two Laval nozzles by the Jet injector of will taking a sample, and the power source of Jet injector is carried out secondary quicken, and has improved the flow velocity of the power source of sampling Jet injector, thereby has increased the suction force of sampling Jet injector.Thereby make not reach under the needed situation of analytical instrument, analytic sample is sucked enters analytical instrument, thereby analytical instrument can be analyzed normally to analytic sample at original analytic sample pressure.In addition, the utility model embodiment has made things convenient for the maintenance of sampling Jet injector among the utility model embodiment and the replacing of its parts also by being provided with service port.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
