Description

[Detailed Description of the Invention] The present invention relates to an improvement of the primary air conditioning mechanism of a gas burner, and is intended to make it possible to obtain a highly accurate primary air amount that matches the quality of the gas used with simple operations.

Conventionally, various primary air adjustment mechanisms have been provided that can vary the amount of primary air in the burner according to the quality of the gas used in order to achieve optimal combustion in the burner, but all of them have complicated adjustment mechanisms and are unnecessarily costly. However, if it is a continuously variable type, it requires skill to set it accurately, so no further improvements have been made.

In view of these points, this project was devised to solve this problem, and it allows for adjustment of the primary air intake amount with an extremely simple structure, making it possible to adjust with high precision and without individual differences. This is what I did.

Embodiments of the present invention will be described below based on the drawings.

A cylindrical damper mounting part 2 is formed by extending to the mixing pipe inlet of the burner body 1, and an intake hole 3 of an appropriate size larger than the damper side intake hole described later is provided at an appropriate location in the mounting part. is forming.

Reference numeral 4 denotes a damper locking piece formed on the side surface of the damper mounting portion 2, which locks a cutout of the damper, which will be described later.

Incidentally, in a metal plate press burner, a joint flange portion formed by press working may be used as the damper locking piece.

5 is a damper that substantially regulates the intake amount of primary air, and is shaped so as to approximately fit into the mounting portion 2 of the burner;
A number of notches 6 are formed at one end to engage the damper locking piece 4, and an intake hole 7 having an intake area suitable for various types of gas is bored in the intermediate body.

8 is a gas quality index used in the intake hole 7.

In addition, FIG. 4 shows a damper formed by making the shape of the intake hole 70 circular and slightly overlapping other circular holes when viewed in the axial direction.
It is functionally similar to the damper 5 of the first embodiment.

When using this in such a configuration, the burner body 1
Attach the damper 5 to the damper mounting part 2 with the notch 6 first, overlap the intake hole 7 that matches the quality of gas used with the burner side intake hole 3, and then fit it to the damper locking piece 4 of the burner. The notch 6 of the damper is locked to the locking piece.

Furthermore, when changing the gas quality, the damper 5 may be pulled out until the notch is unlocked, the intake hole may be rotated, and the damper 5 may be overlapped with the burner side intake hole 3 and locked.

As mentioned above, this proposal consists of a cylindrical damper with many notches formed at one end and many intake holes suitable for various gas types on the other side, and a damper mounting part at the inlet of the mixing pipe. It consists of a burner body that has an appropriately sized intake hole on its circumferential surface and a locking piece that can lock the damper notch, and the intake hole for the gas used in the damper is overlapped and engaged with the burner side intake hole. Since the primary air intake amount can be set without any special skills or knowledge,
In other words, reliable adjustments can be made with no individual differences.

In addition, this adjustment work can be done by making the length of the damper mounting part slightly longer than the damper length, so that the damper can be engaged and disengaged by sliding and turning with the damper attached, without having to manipulate any other parts or equipment. From this point of view as well, it is possible to achieve practical effects with very excellent workability.
