Abstract
The utility model discloses a guide seal sleeve, which is used to measure wind speed of a positive pressure smoke wind duct and sample pulverized coal in a wind powder pipe, and comprises two connecting casings with fixed holes and sleeve rings, wherein the sleeve rings are sleeved on the two ends of the two connecting casings. The guide seal sleeve improves measurement accuracy and seal performance by being combined with a standard pitot tube or a pulverized coal sampling device to use, can effectively prevent dust or high temperature gas in a smoke wind duct from leaking, and increases cleanliness of operation sites and safety of operators.
Description
Technical field
A kind of pilot seal cover when the utility model relates to the sampling of coal dust in the measurement that is applied to malleation cigarette air channel wind speed and wind powder pipe road.
Background technology
In the measurement of Utility Boiler ' Duct wind speed and wind powder pipe road, the sampling of coal dust is the conventional test project of boiler of power plant.When measuring wind speed and coal dust sampling, the method for employing is perforate on pipeline at present, and testing crew inserts pipeline with pitot tube or coal fines sampling apparatus, then with rag, the gap between pitot tube and perforate is blocked, and prevents the leakage of flue gas and dust.The drawback that current method exists: the one, need to measure the data of a plurality of measuring points in measuring process, require pitot tube (coal fines sampling apparatus) perpendicular to airflow direction, and measuring point must be positioned at circular pipe radially or be parallel to the length of side of rectangular duct, because site environment is more abominable, testing crew is wayward, causes the test accuracy lower; The 2nd, not tight with the rag leak stopping, the pull pitot tube is not easy to operate yet, when especially measuring the high-temperature flue gas pipeline, easily causes testing crew to scald.
The utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly improves the accuracy of measurement, effectively prevents that dust or high-temperature gas in the cigarette air channel from leaking, improving the guiding-sealing device that the cigarette wind powder pipe road of the cleaning of operation field and operating personnel's security is measured.
The technical solution adopted in the utility model is as follows:
The utility model is by with two connecting pipes cover of fixed orifice and be sleeved on described two collars that connect pipe box two ends and consist of.
Two connecting pipes cover described in the utility model and be sleeved on described two collars that connect pipe box two ends and adopt and be threaded.
good effect of the present utility model is as follows: when cigarette air channel measuring wind speed or coal dust sampling, utilize the utility model and standard pitot tube or coal fines sampling apparatus to be used in combination, have two aspect advantages: the one, improve the accuracy of measuring, because the fixed orifice of pilot seal cover is processed according to the diameter of pitot tube or coal fines sampling apparatus, as long as the base of pilot seal cover correctly is arranged on pipeline, just can guarantee pitot tube or coal fines sampling apparatus be positioned at circular pipe radially or be parallel to the length of side of rectangular duct, make pitot tube or coal fines sampling apparatus perpendicular to airflow direction, the 2nd, good airproof performance, because the fixed orifice of pilot seal cover is processed according to the diameter of pitot tube or coal fines sampling apparatus, gap between pitot tube or coal fines sampling apparatus and sealing shroud is very little, can prevent effectively that dust or high-temperature gas in the cigarette air channel from leaking, and improves the cleaning of operation field and operating personnel's security.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
In the accompanying drawings: 1 fixed orifice, 2 connects pipe box, 3 collars, 4 pitot tubes, 5 pedestals.
Embodiment
As shown in Figure 1, the utility model consists of by connecting pipe boxes 2 and be sleeved on described two collars 3 that connect pipe box 2 two ends with two of fixed orifice 1.In use, with pitot tube 4(or coal fines sampling apparatus) put into by pitot tube 4(or coal fines sampling apparatus) there is the fixed orifice 1 of externally threaded connection pipe box 2 at the two ends of caliber processing, fixing with the female collar 3 of processing, then with pitot tube 4(or coal fines sampling apparatus) put into measuring channel, the utility model is arranged on the pedestal 5 of measuring channel, the internal thread on pedestal 5 matches with the external thread that is connected pipe box 2 outermost end.
Claims (2)
1. pilot seal cover is characterized in that it consists of by connecting pipe boxes (2) with two of fixed orifice (1) and being sleeved on described two collars (3) that connect pipe box (2) two ends.
2. pilot seal cover according to claim 1 is characterized in that described two connect pipe boxes (2) and are sleeved on described two collars (3) that connect pipe box (2) two ends and adopt and be threaded.
