Description
Technical field
The utility model belongs to instrument field, and in particular to a kind of more gas detecting instruments.
Background technique
Pernicious gas detection is important safeguard procedures in industrial production；Gas detecting instrument is a kind of gas leakage concentration inspection
The instrument and meter tool of survey, including refer to portable gas detector, hand-held gas detecting instrument, stationary gas detector and
Wire type gas detecting instrument mainly detects gaseous species present in environment using gas sensor, gas sensor be for
The ingredient of detection gas and the sensor of content.More gas-detecting devices generally comprise detection probe, connect with detection probe
Data conversion module, the host with data conversion module communication connection.Detection probe is critical component, the inspection on existing detector
Probing header structure is simple, influences detection accuracy.
Utility model content
The purpose of this utility model is to provide a kind of more gas detecting instruments, to solve detection probe on existing detector
Structure is simple, influences the problem of detection accuracy.
To achieve the above object, the following technical solution is employed: more gas detections for more gas detecting instruments of the utility model
Instrument includes detection probe, and detection probe includes shell and gas detection probe, and shell has gas passage for gas to pass through, work
Gas flow forward in gas passage to be detected when making, gas detection probe have multiple, and each gas detection probe is logical along gas
The setting of road interval, the test side of gas detection probe are protruded into gas passage, in gas passage before each gas detection probe
A spoiler is distinguished in side, and spoiler is detachably arranged in gas passage, is the globoidal structure to front projection in the middle part of spoiler,
Part on spoiler higher than the test side of gas detection probe has ventilating structure for gas to pass through, the portion lower than test side
Divide with the baffle structure for stopping gas to flow.
The utility model has the advantages that gas from gas passage one end enters gas passage when work, gas part when by spoiler
Gas flow is changed, gaseous exchange near the test side of gas detection probe, and nearby gas flow rate is very low for test side, baffle knot
Structure separates adjacent gas detection probe, and convenient for probe detection, and each probe detection is independent of each other.Compared with the prior art, right
Detection probe structure improves, and improves more gas detecting instrument detection accuracy.
Further, the test side of gas detection probe is lower than gas passage center line, is higher than gas passage on spoiler
The part of center line is ventilating structure, lower than the part of gas passage center line is baffle structure.
Further, shell includes outer cover and the circular pipe that is mounted in outer cover, and circular pipe forms institute through outer cover
Gas passage is stated, circular pipe includes the pipe nipple of two sections or more, is spirally connected between adjacent pipe nipple；Spoiler radial edges, which are equipped with, turns up
Edge turns edge be pressed between adjacent pipe nipple outside.
Further, the spoiler is formed by stainless-steel sheet integrated punching.
Detailed description of the invention
It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the embodiments of the present invention, for this
For the those of ordinary skill of field, without any creative labor, it can also be obtained according to these attached drawings other
Attached drawing；
Fig. 1 is the structural schematic diagram of the specific embodiment of more gas detecting instruments of the utility model；
Fig. 2 is the left view of Fig. 1.
In figure: 1- shell, 2- gas detection probe, 3- outer cover, 4- pipe nipple, 5- spoiler, 6- ventilating structure, 7- baffle
Structure, the test side 8-.
Specific embodiment
In order to keep the technical purpose, technical scheme and beneficial effects of the utility model clearer, with reference to the accompanying drawing and
Specific embodiment is further illustrated the technical solution of the utility model.
As shown in Figure 1 to Figure 2, more gas detecting instruments include detection probe, and detection probe includes the gentle physical examination probing of shell 1
First 2, shell 1 includes outer cover 3 and the circular pipe being mounted in outer cover 3, and circular pipe forms gas passage, circle through outer cover 3
Shape pipeline includes the pipe nipple 4 of two sections or more, and adjacent pipe nipple 4 is spirally connected；Gas detection probe 2 has multiple, 2 upper end of gas detection probe
For test side 8, each gas detection probe 2 is arranged along gas passage interval, and test side 8 is protruded into gas passage；Gas detection is visited
The test side 8 of head is lower than gas passage center line.
A spoiler 5 is distinguished in the front side of each gas detection probe 2 in gas passage, and spoiler 5 is removably mounted on
In gas passage, for the arc surface structure of front projection, 5 radial edges of spoiler are equipped with and turn edge outside, turn edge outside in the middle part of spoiler 5
Between adjacent pipe nipple 4 and it is compacted.The part for being higher than gas passage center line on spoiler 5 is ventilating structure, is lower than gas
The part of body channel centerline is baffle structure.Spoiler 5 in the present embodiment is formed by stainless-steel sheet integrated punching, is breathed freely
Structure is formed by the air hole on spoiler 5.
Gas to be detected enters from gas passage one end when work, when gas passes through spoiler 5 gas passage center line with
The gas of lower part is blocked, and gas flow changes, gaseous exchange near test side 8, and nearby gas flow rate is very low for test side 8,
Convenient for probe detection, and baffle structure 7 separates adjacent gas detection probe 2, and each probe detection is made to be independent of each other.Compared to
The prior art improves detection probe structure, improves detector test precision.
In other embodiments, gas passage can also be arranged to rectangular channel, it is corresponding that spoiler rim is arranged
It is rectangular.In addition, on position of the gas detection probe in gas passage, spoiler on ventilating structure position and spoiler
Baffle locations of structures can adjust according to actual needs.Alternatively, it is also possible to which spoiler is fixed on gas passage using other modes
It is interior, such as screw connection.
It should be noted last that: the technical solution of the utility model that the above embodiments are only illustrative and not limiting is appointed
What to the utility model carry out equivalent replacement and do not depart from the spirit and scope of the utility model modification or part replace,
It should cover within the scope of the utility model claims protection.
