Description

One-button flameout protection switch assembly

Technical Field

The utility model relates to a key formula flame-out protection switch assembly.

Background

A one-key flameout protection switch assembly is used for controlling and distributing small fuel gas, large fuel gas and long open flame fuel gas on a high-fire stove, for example, a one-key flameout protection switch assembly with an authorized bulletin number of CN217131344U, and mainly comprises a valve body, an ignition controller, a thermocouple, an induction needle, an ignition needle and a long open flame sub-controller, wherein a high-fire air supply pipe and a small flame air supply pipe are respectively arranged on the valve body

The gas supply pipe and the gas inlet pipe are connected with the pilot burner branch controller through a branch pipe. The small fire air supply pipe of this kind of current key formula flame-out protection switch assembly does not set up the tolerance regulator with between being in charge to can not general liquefied gas and natural gas simultaneously, because the atmospheric pressure of natural gas and liquefied gas is different, use different gas and do not change the gas output that can make long open fire branch accuse ware too big or the undersize of being in charge, the induction needle and ignition needle can be burnt out to the gas output too big, the gas output undersize will make long open fire extinguish, it is very troublesome again if often change the branch pipe.

SUMMERY OF THE UTILITY MODEL

In view of the defect that current key formula flame-out protection switch assembly exists, the utility model discloses the technical problem that will solve is: the utility model provides a key formula flame-out protection switch assembly that small fire intake pipe tolerance can be regulated and control.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a one-touch flameout protection switch assembly comprising: the valve body is provided with a strong fire air supply pipe, a small fire air supply pipe and a fuel gas inlet pipe which are mutually communicated,

the small fire air supply pipe is provided with an air volume regulator which comprises a seat body, a regulating needle and a fixing nut,

two ends of the seat body are respectively provided with a threaded rod, an air passage is arranged between the two threaded rods, an internal thread is arranged at the air passage of one threaded rod, the outer side of the seat body is also provided with a connecting hole which is communicated with the air passage and the inner wall of which is provided with a connecting thread,

one end of the adjusting needle is conical, a connecting threaded pipe which can be screwed with the internal thread of the threaded pipe is also arranged on the adjusting needle,

the fixing nut is characterized in that an opening on one side of the fixing nut is hollow, an internal thread is arranged on the inner wall of the nut, a through hole for allowing the other end of the adjusting needle to be connected in a penetrating mode is further formed in the closed end opposite to the opening end, the nut can be connected with a threaded rod with the internal thread in a rotating mode, and the conical end of the adjusting needle can adjust the closed state of the connecting hole.

According to the one-button flameout protection switch assembly, the air volume regulator is arranged on the small fire air supply pipe of the valve body and is connected with the long open fire air supply pipe through the air volume regulator, and the regulating needle can enter and exit along the air passage of the seat body by rotating the regulating needle of the air volume regulator, so that the conical end of the regulating needle seals the opening at the inner end of the connecting hole of the seat body to regulate the ventilation volume.

Furthermore, a sealing ring is sleeved on the adjusting needle and is positioned in the nut and abuts against the closed end of the nut for sealing.

Furthermore, the penetrating end of the adjusting needle penetrating through the fixing nut is provided with an inserting groove for inserting a screwdriver.

Compared with the prior art, the utility model has the advantages of: the one-key flameout protection switch assembly has stronger applicability, and the long open fire air supply pipe does not need to be replaced even if the type of gas is frequently replaced, so that the use is more convenient.
