Abstract

The utility model discloses a gas valve, which comprises a valve body and a valve seat, a valve core is installed in a cavity formed by the valve body and the valve seat, the valve core is provided with two small-fire air inlet holes and two large-fire air inlet holes located on the same circumference, and the valve body is provided with an air inlet passage matched with the air inlet holes, which changes the current situation that the traditional air inlet holes are not on the same circumference and the valve body needs to be provided with a "human"-shaped air inlet passage to communicate with the air inlet holes located on the two circumferences, reduces the difficulty of processing, reduces the production cost, and enhances the competitiveness of the product in terms of cost performance.

Description

a gas valve

technical field

The utility model relates to a gas valve, in particular to a gas valve with simple structure and convenient processing.

Background technique

At present, the air intake holes on the valve core of the gas valves on the market are not on the same circumference, so the air intake passages on the valve body must be set in a "herringbone" shape to match the air intake holes on the two circumferences of the valve core respectively. In other words, this brings certain difficulties to processing, resulting in low production efficiency and high production costs, making this type of product lack of market competitiveness and unable to meet the needs of the market.

Contents of the invention

In order to overcome the shortcomings of the prior art, the utility model provides a gas valve with simple structure and convenient processing.

The technical scheme that the utility model solves its technical problem adopts is:

A gas valve, including a valve body and a valve seat, the valve body is equipped with a nozzle, the nozzle is provided with a nozzle hole, a valve core is installed in the cavity formed by the valve body and the valve seat, and one end of the valve core is provided with a blind hole, the blind hole The inner air passage communicates with the nozzle hole, and the other end is connected with a rotating shaft. The valve core is provided with a small fire air inlet and a large fire air inlet, and the small fire air inlet and the large fire air inlet are located on the same circumference. The valve body is provided with an air inlet channel matched with the air inlet hole.

As a further improvement of the utility model, the valve core is provided with two small-fire air inlets and two large-fire air inlets.

The beneficial effects of the utility model are: the valve core of the utility model is provided with a small fire air intake hole and a large fire air intake hole, the small fire air intake hole and the large fire air intake hole are located on the same circle, and the valve body is provided with a The air inlet channel with matching holes has changed the current situation that the traditional air inlet holes are not on the same circumference, and the valve body needs to be provided with "herringbone" shaped air inlet channels that communicate with the air inlet holes located on the two circumferences respectively, reducing the The difficulty of processing reduces production costs and enhances the competitiveness of products in terms of cost performance.

Detailed ways

Referring to Figures 1 to 6, a gas valve includes a valve body 1 and a valve seat 2, the valve body 1 is equipped with a nozzle 3, the nozzle 3 is provided with a nozzle hole, and a valve core is installed in the cavity formed by the valve body and the valve seat 4. One end of the valve core 4 is provided with a blind hole 8, the blind hole 8 communicates with the nozzle hole through the inner air passage 9, and the other end is connected with the rotating shaft 5, and the valve core is provided with two small fire air inlet holes 6 and two The large fire air intake hole 7, the two small fire air intake holes 6 and the two large fire air intake holes 7 are located on the same circumference, and the valve body 1 is provided with air intake ports that match the above air intake holes 6,7. Road 10, the pipeline interface 12 is installed in the air inlet 10, and the gas pipeline is connected after adopting a rubber gasket 11 to seal. According to the diameter of air inlet 10, the included angle between the small fire air inlet 6 and the big fire air inlet 7 is set, when the valve core 4 can be turned to a certain angle, the part of the big fire air inlet 7 and the small fire inlet Part of the air hole 6 is ventilated at the same time, so that the continuous change of the combustion flame from small to large can be realized. The gas valve of the utility model adopts the above-mentioned structure, which changes the current situation that the traditional air intake holes are not on the same circumference, and the valve body needs to be provided with "herringbone"-shaped air intake passages to communicate with the air intake holes located on the two circumferences respectively. The difficulty of processing is reduced, and the production cost is reduced.
