Abstract
The utility model relates to a cooling wind cover of a flame detecting probe of a flame detector, which is fixed on an inner conduit of the flame detector, and comprises a casing body whose both ends are respectively fixed with a first end cover and a second end cover to form a cavity body for placing the fire detecting probe, a probe connector which is arranged on the first end cover on one end of the casing body, one end of the probe connector is arranged in the cavity body of the casing body, and the other end is connected with the inner conduit of the flame detector, a first pipe joint which is fixed on the first end cover and is externally connected with a wind outlet pipe, a second pipe joint which is fixed on the second end cover on the other end of the casing body and is externally; connected with a wind inlet, an aviation joint which is fixed on the second end cover, and comprises a female joint and a male joint, wherein the female joint is fixed on the inner side of the second end cover, one end of the male joint passes through the second end cover and is inserted into the male joint, a connecting pipe whose one end is connected on the male joint and the other end is connected with the fire detecting probe in the cavity body of the casing body. The cooling wind cover can guarantee that the environment working temperature of the fire testing probe to be normal, which avoids unnecessary loss which is caused by abnormal stopping of a boiler after the probe is abnormally detected.
Description
Technical field
The utility model relates to the flame detector field, particularly a kind of flame detector flame detecting probe cooling fan housing that is used for flame testing environment temperature overtemperature prote.
Background technology
The insulation of the boiler-burner that uses at home at present mainly contains dual mode, promptly interior insulation and outer insulation.
The scene insulation is carried out when interior heat preserving mode generally has the boiler factory to dispatch from the factory, the general effect of heat insulation of this mode is relatively good, and is on-the-spot because the radiation heat of boiler internal compares less.
Outer heat preserving mode boiler insulation is solved by the scene, after boiler-burner installs, is responsible for insulation by the scene, because the site operation aspect, the insulation that has is handled all right, and the insulation that has is handled poor, cause the radiation heat of boiler too high, influence the use of field probe.In addition, the insulation of the pulverized coal channel of the power plant that has is also poor, the perhaps thermal-insulating sealing weak effect at burner place, cause the working environment overtemperature of fire inspection, cause the flame detecting probe overtemperature, make fire inspection cisco unity malfunction, the serious fire inspection that causes damages, cause boiler out of service, bring unnecessary loss to power plant.
The operating ambient temperature of general fire inspection should be less than 70 ℃; but because on-the-spot a variety of causes; cause environment temperature too high; the rising of environment temperature, the detection of influence fire inspection and the serviceable life of fire inspection, therefore; in order further effectively to protect flame detecting probe; safeguard simultaneously to reduce cost and effectively detection that the utility model provides a kind of novel cooling fan housing of cooling probe by improving the working environment of fire inspection.
Summary of the invention
The purpose of this utility model is to provide a kind of flame detector flame detecting probe cooling fan housing; can protect flame detecting probe effectively; reduce maintenance cost; the ambient operating temperature that guarantees flame detecting probe is normal; make execute-in-place simple simultaneously; be convenient to safeguard and reduce and safeguard, avoid probe to detect causing after undesired that boiler is non-stops, cause unnecessary loss.
To achieve these goals, the technical solution of the utility model:
A kind of flame detector flame detecting probe cooling fan housing is fixed on the inner catheter of flame detector, comprises, and housing, first, second end cap is fixed at its two ends respectively, forms the cavity that a confession is provided with flame detecting probe; Probe connector is arranged on first end cap of housing one end, and the one end is positioned at shell cavity; The other end flame detecting device inner catheter of starting to exchange fire; First pipe adapter is fixed on first end cap, picks out airduct; Second pipe adapter is fixed on second end cap of the housing other end external blast pipe; Aviation Connector is fixed on second end cap, comprises female joint, male joint; The second end cap inboard is fixed in female joint, and an end of male joint passes second end cap and is inserted in the female joint; Connecting pipe, an end is connected in male joint, and the other end is connected with flame detecting probe in the shell cavity by a sheath.
Described male joint is passed through packing ring, film and screw retention on second end cap.
Described connecting pipe is a flexible pipe.
The beneficial effects of the utility model
The utility model is to the protection employing cooling air cooling mode of flame detecting probe, and simplified structure by cooling air cooling flame detecting probe, lowers the environment temperature of fiery inspection work, simultaneously behind the former interior outer catheter of cooling air introducing optical fiber being cooled off.To the protection of flame detecting probe be improved significantly, structure is also fairly simple.
