Abstract

The utility model discloses a gas valve. The gas valve comprises a valve body and a valve seat; a valve core mounted in the space formed by the valve body and the valve seat is connected with a rotating shaft inserted into the valve seat; the valve body is provided with a main fire gas channel and an ignition gas channel; a main fire nozzle is mounted at the tail end of the main fire gas channel;a connecting piece is fixed on the valve body or the valve seat; an ignition nozzle is fixed at the tail end of the connecting piece; and the ignition gas channel and the ignition nozzle are communicated through a gas guide branch pipe, so that the positions of the main fire nozzle and the ignition nozzle can be flexibly changed without changing the main structure of the prior gas valve to suit various burners. By adopting the gas valve, the development and mold opening cost is reduced and the manufacturing cost is reduced, and the gas valve can be widely applied to a gas stove, a gas BBQ grill, a gas water heater, and the like.

Description

A kind of gas valve

Technical field

The utility model relates to a kind of gas valve.

Background technology

Existing gas valve comprises valve body and valve seat, in the space that constitutes by valve body and valve seat spool is installed, spool is connected with the rotating shaft that interts valve seat, valve body is provided with main fire-steam passsage and igniting air flue, the end of main fire-steam passsage and igniting air flue is separately installed with the main fire-fighting nozzle of chewing and light a fire, main fire-fighting is chewed terminal concordant with the nozzle of lighting a fire, and in some special application facet, position as ignition gas inlet and main internal heat body inlet differs bigger, the way of prior art is the method realization by prolonging the igniting air flue or prolonging the igniting nozzle, so, need redesign and offered mould, cause the increase of production cost.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides under a kind of situation that does not change valve body structure, can adapt to the gas valve of various ignition gases inlets and main internal heat body inlet.

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

A kind of gas valve, comprise valve body and valve seat, in the space that constitutes by described valve body and valve seat spool is installed, described spool is connected with the rotating shaft that interts valve seat, described valve body is provided with main fire-steam passsage and igniting air flue, and the end of described main fire-steam passsage is equipped with main fire-fighting and chews, and is fixed with one in flakes on described valve body or the valve seat, described end in flakes is fixed with the igniting nozzle, and described igniting air flue and igniting nozzle are communicated with by air-guide branch pipe.

The beneficial effects of the utility model are: be fixed with one in flakes on valve body of the present utility model or the valve seat, the igniting nozzle is fixed on end in flakes, igniting air flue and igniting nozzle are communicated with by air-guide branch pipe, can be under the situation that does not change existing gas valve agent structure, change neatly that main fire-fighting is chewed and the position of the nozzle of lighting a fire, to adapt to various burner, reduced the expense of research and development and die sinking, reduce production cost, can be widely used in gas-cooker, fuel baking oven or gas heater etc.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1, a kind of gas valve, comprise valve body 1 and valve seat 2, in the space that constitutes by described valve body 1 and valve seat 2 spool is installed, described spool is connected with the rotating shaft 3 that interts valve seat 2, described valve body is provided with main fire-steam passsage and igniting air flue, the end of described main fire-steam passsage is equipped with main fire-fighting and chews 4, be fixed with one in flakes 5 on described valve body 1 or the valve seat 2, described 5 end in flakes is fixed with igniting nozzle 6, described igniting air flue and igniting nozzle 6 are communicated with by copper air-guide branch pipe 7, are fixed with priming supply 8 on the valve seat 2, and priming supply 8 connects the electron gun 10 that is arranged on igniting nozzle place by lead 9.

Because the igniting nozzle is fixed on end in flakes, igniting air flue and igniting nozzle are communicated with by air-guide branch pipe, can be under the situation that does not change existing gas valve agent structure, change neatly that main fire-fighting is chewed and the position of the nozzle of lighting a fire, to adapt to various burner, reduce the expense of research and development and die sinking, reduced production cost, can be widely used in gas-cooker, fuel baking oven or gas heater etc.

Claims (2)

1, a kind of gas valve, comprise valve body (1) and valve seat (2), in the space by described valve body (1) and valve seat (2) formation spool is installed, described spool is connected with the rotating shaft (3) of interspersed valve seat (2), described valve body is provided with main fire-steam passsage and igniting air flue, the end of described main fire-steam passsage is equipped with main fire-fighting and chews (4), it is characterized in that being fixed with on described valve body (1) or the valve seat (2) one (5) in flakes, the described end of (5) in flakes is fixed with igniting nozzle (6), and described igniting air flue and igniting nozzle (6) are communicated with by air-guide branch pipe (7).

2, a kind of gas valve according to claim 1 is characterized in that described air-guide branch pipe (7) is a copper pipe.
