Description
Technical field
The utility model patent relates to checkout gear, and particularly, the utility model relates to a kind of flame and detects connector, and more specifically, the utility model relates to a kind of flame that possesses the self-cleaning function and detects connector.
Background technology
Natural gas and coal gas act as a fuel and are applied in the commercial production more and more extensively.When natural gas and coal gas mix with a certain proportion of air, if having certain energy this moment, will set off an explosion, cause ill effect.
In order to ensure the safety of using natural gas and coal gas, just must the detection natural gas and coal gas normal combustion whether.If natural gas and coal gas is burning not, just do not allow igniting, and the operation of lighting a fire again after should first emptying mist.
Heating furnace uses the mixture burns of air and coal gas to come processing medium is heated usually.For guaranteeing the coal gas normal combustion, in interlock circuit, be equipped with the flame detection signal usually.When no flame detection signal, heating furnace interlocked control program start cuts off coal gas and air supply valve automatically, guarantees the safety of producing.
The effect of flame detector is exactly whether detect combustion gas normal.When flame detector detects flame, just export the signal that burnt and give the control system.If flame monitor does not detect flame, the control system will start interlock program immediately, stops fuel gas buring.Therefore, whether flame detector operate as normal, and whether be related to gas burning system can long-time steady operation.Therefore, whether flame detector work normally will directly influence the job stability of heating furnace.
General flame detector is installed in more than the horizontal level, and flame-detecting probe down.So install, can avoid the rubbish in the heating furnace to drop on the flame-detecting probe.But, many heating furnaces are arranged because burner is arranged on the heating furnace bottom, and around the heating furnace thicker insulation heat insulation layer is arranged all, be unfavorable for the installation of flame monitor.But when flame monitor was installed in the heating furnace bottom, the insulation material in the stove can produce certain dust when fuel gas buring.When these dust are fallen on the flame-detecting probe, the flame of flame-detecting probe and detection is isolated, output misfire signal, thereby pneumatic interlocking control program.In addition, combustion gas in stove like burn incompletely, buildup on furnace tubing sometimes, these solid particulate matters also can drop on flame-detecting probe, influence the normal measurement of flame detector.
When flame monitor is installed to heating furnace, must use connector to connect.
For the long-time correct measurement flame of ability, need a kind of a kind of connector that can the dust granules thing be purged out flame-detecting probe of invention.This joint can also cool off the temperature of flame-detecting probe when purging the dust granules thing, prolong the life-span of flame-detecting probe.
The utility model content
For overcoming the problems referred to above, the utility model purpose is, provides a kind of flame that possesses the self-cleaning function to detect connector.Said flame detects connector when purging the dust granules thing, can also cool off the temperature of flame-detecting probe, prolongs the life-span of flame-detecting probe.

A kind of flame that possesses the self-cleaning function according to the utility model detects connector, it is characterized in that the spacing between the said first purging air pipe, the second purging air pipe is 80-100mm.
On the first purging air pipe and 2, install the blowing plant that air pressure is 100kPa additional.
The first purging air pipe key is to purge the dust that top is come.When dust detects the connector body near flame, can make it depart from the connector body.And the effect of the second purging air pipe is that the dust that gets into the connector body is blown away;
The flame that possesses the self-cleaning function according to the utility model a kind of detects connector, it is characterized in that, offers the circular port of Φ 4mm in connector body and the flame monitor junction of popping one's head in.
Thus, open the circular port of Φ 4mm in threaded connection place of connector and flame monitor probe.When in the second purging air pipe air being arranged, can the dust on the flame-detecting probe be blown away from circular port.
The flame that possesses the self-cleaning function according to the utility model a kind of detects connector, it is characterized in that, opens the circular port of 4 Φ 4-6mm in threaded connection place of popping one's head in of connector body and flame monitor.
A kind of flame that possesses the self-cleaning function according to the utility model detects connector, it is characterized in that, said connector body portion is spherical sealing.
Because of said connector front portion is spherical sealing, can effectively regulate the flame angle.
A kind of flame that possesses the self-cleaning function according to the utility model detects connector, can when purging the dust granules thing, can also cool off the temperature of flame-detecting probe, prolongs the life-span of flame-detecting probe.
A kind of flame that possesses the self-cleaning function according to the utility model detects connector, it is characterized in that, the spherical seals at of said connector body portion is provided with packing ring.
A kind of flame that possesses the self-cleaning function according to the utility model detects connector, it is characterized in that said connector body portion is with flange and bolt.
