For solving the problems of the technologies described above, the utility model provides a kind of sampling probe for low dust sample gas, by casing, be installed on the body assembly in described casing, the sample gas import that is opened in described casing and the outlet of sample gas, the power lead entrance hole and the incoming line of stopple coupon, the connecting terminal members that is installed in described casing that are opened in described casing form.
Preferably, described body assembly comprises the probe body, is installed on this external probe muff of described probe, is located at the outer sealing gasket of described probe muff.
Preferably, described body assembly also comprises the heating tape, and described heating tape is arranged at outside described probe muff.
Preferably, also comprise temperature-sensing element, described temperature-sensing element is arranged between described probe muff and described heating tape.
Preferably, described temperature-sensing element is temperature sensor.
Preferably, described casing is shaped as rectangular parallelepiped.
Preferably, the length of described casing is 300mm, and its width is 300mm, and it is highly 255mm.
Sampling probe provided by the utility model is used for the sampling operation of low dust sample gas, this sampling probe by casing, be installed on the body assembly in described casing, the sample gas import that is opened in described casing and the outlet of sample gas, the power lead entrance hole and the incoming line of stopple coupon, the connecting terminal members that is installed in described casing that are opened in described casing form; This sampling probe has removed the blow device of existing sampling probe, it is the sampling operation that is used in the operating mode of hanging down dust due to this sampling probe, so need not body assembly is purged, blow device was exactly unnecessary parts originally, and having removed blow device can not affect the normal operation of sampling probe; Simultaneously, after having cancelled blow device, the volume of casing has obtained dwindling, thereby has dwindled the volume and weight of sampling probe, makes it install and use at small space Nei Gengyi.
In a kind of embodiment, the body assembly of sampling probe provided by the utility model also comprises the heating tape, and the heating tape is arranged at outside the probe muff; Development along with the industrial automation technology, the gas sample of some circumstance complications, inclement condition operating mode just needs the sampling equipment of specialty, power plant's kiln tail electricity position of gathering dust for example, probe temperature is higher, and sample gas water cut is larger, brings obstruction for preventing from lowering the temperature rapidly after sample gas out, avoid the water vapour generation condensation in sample gas, set up the heating tape in sampling probe, with heating sample gas, guarantee that sample gas has higher temperature all the time.
In another kind of embodiment, sampling probe provided by the utility model also comprises temperature-sensing element, described temperature-sensing element is arranged between probe muff and heating tape, in order to monitor the temperature of heating tape, thereby according to requirements adjusts the temperature of heating tape.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of sampling probe provided by the utility model.
Embodiment
Core of the present utility model is to provide a kind of sampling probe for low dust sample gas, and it can either satisfy sampling requirement, has again less volume and weight, installs more for convenience.
In order to make those skilled in the art person understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of embodiment of sampling probe provided by the utility model.
In a kind of embodiment, sampling probe provided by the utility model is used for extracting the operation occasion of low dust sample gas, and this sampling probe is comprised of casing 1, the incoming line 5 that is installed on the body assembly 2 in casing 1, the sample gas import that is opened in casing 1 and sample gas outlet 3, the power lead entrance hole 4 that is opened in casing 1 and stopple coupon, the connecting terminal members 6 that is installed in casing 1; This sampling probe has removed the blow device of existing sampling probe, it is the sampling operation that is used in the operating mode of hanging down dust due to this sampling probe, so need not body assembly 2 is purged, blow device was exactly unnecessary parts originally, and having removed blow device can not affect the normal operation of sampling probe; Simultaneously, after having cancelled blow device, the volume of casing 1 has obtained dwindling, thereby has dwindled the volume and weight of sampling probe, makes it install and use at small space Nei Gengyi.
Above-mentioned casing 1 is used for holding body assembly 2 parts such as grade, and body assembly and the external world are separated, with seal body assembly 2..
The long cable section of ingoing line of the power supply of sampling probe enters casing from said power entrance hole 4, and the casing arranged outside of this power lead entrance hole 4 has Waterproof cable joint, is connected with power lead by this Waterproof cable joint.
