Go out higher requirement.
Summary of the invention
The purpose of this utility model is, in order to realize boiler of power plant square-section multi-pipeline synchronized sampling, again can be to single
Independent measuring point is individually sampled and multiple measuring points can also be carried out sampling functions in turn, the open a kind of electricity of this utility model
The multi-functional sampling gun of boiler multi-pipe formula of standing.
The technical solution of the utility model is, a kind of multi-functional sampling gun of station boiler multitube, including sampling tube, fixes
Ring, also includes thermocouple sheath, ladder base, the tee T of band control valve, control valve, mixed sampling pipe, blender and thermoelectricity
Even temperature inserts handle；There are centre bore in circular ladder base central authorities, be evenly distributed with on the circumference of centre bore multiple identical directly
The sampling pore in footpath；Thermocouple sheath is arranged in the centre bore of ladder base, and the multiple sampling pores on ladder base are installed
There are many sampling tubes of different length；The rear portion of thermocouple sheath and sampling tube is fixed by ladder base, thermocouple sheath and adopting
The sampling tube of thermocouple sheath is fixed by the front portion of sample pipe by retainer ring；The rear end of sampling tube equipped with band control valve tee T and
Control valve；The end, rear end of sampling tube is provided with blender；Mixed sampling pipe is installed on blender and electric thermo-couple temperature inserts handle；
Electric thermo-couple temperature is inserted the tail end connecting thermocouple sheath.
Multiple slotted eye has uniformly been offered, the long axis direction of slotted eye on the radial direction casing wall of described thermocouple sheath
Radially consistent with thermocouple sheath.
Described thermocouple sheath, equipped with the equal thermocouple of same steel pipe quantity and length, can meet the same of smoke sampling simultaneously
Be connected with the external world by output lead slotting of Shi Jinhang temperature survey and every thermocouple.
Described mixed sampling pipe and blender are the gathering tubes of many sampling tubes, are aggregated into by the smoke components that every is sampled
In blender, blender communicates with every sampling tube but exports only one of which.
Described sampling tube is respectively arranged with the tee T of a band control valve after ladder base, and equipped with control before entering blender
Valve processed.
Described sampling gun can meet the demands of difference sampling according to test requirements document, can realize that multitube is sampled simultaneously, single tube takes
Sample or multitube carry out sampling requirement in turn, are i.e. regulated by three-way valve with mixed export bleeding point, can the most individually extract each pipe
Flue gas, it is achieved sample in turn.
The beneficial effects of the utility model are, this utility model can be sampled by multitube simultaneously, by the control valve on every sampling tube
Close and open the tee T of all band control valves thus to achieve multitube and externally lead directly to function, it is achieved that multitube exists simultaneously
In flue, different length sample point is sampled, grid survey requirement can be met；Optional single tube sampling, wants according to sampling
Ask optional sampling tube length that single-point is sampled function.Also by blender, multitube is carried out sampling requirement in turn；Will
The tee T of all band control valves cuts out, and utilizes mixed sampling pipe and mixer functionalities, and operation control valve achieves many successively
The function that sampling tube samples successively, it is therefore prevented that single tube is taken out the phenomenon of group hourglass air and shortened the measurement time.
The thermocouple sheath of this utility model center drilling, can be equipped with the equal thermocouple of same steel pipe quantity and length simultaneously
Meet the temperature survey of smoke sampling.
This utility model can carry out the regulation of valve position by sampling gun multi-functional to multitube according to test requirements document before the test, meets
Various requirement in test, can realize the flow measurement requirements such as multitube gridding method total cross-section also can meet single tube measure, simultaneously
Meet requirement that multitube measures successively and synchronization realizes total cross-section temperature survey work.
