Abstract

The utility model relates to a gas fuel valve provided with a lighting switch and has the purpose to provide a gas valve coupled with the lighting switch. The utility model is composed of a valve assembly and a micro switch, wherein, the valve core rod of the valve assembly is provided with a coupling plate whose edge is provided with plate teeth engaged with the opening and closing key of the micro switch. The utility model can supply the gas and ignite electronically synchronously with simple ignition operation and high safety.

Description

A kind of gas valve that links with ignition switch

The utility model includes the gaseous fuel valve of ignition switch.

Existing non-domestic gas device (kitchen range) steam supply valve and ignition mechanism work alone separately, do not interlock mutually, more can not link, and the ignition operation difficulty is given cooperation.When failing the OnNow ignition device opening the gas supply valve, the combustion gas meeting leaks in a large number, now after again igniting then set off an explosion probably, accident such as fire trouble; Before igniting, reduce valve opening if avoid aforementioned accident, then may give and lighting because of valve opening quantity not sufficient, gaseous fuel can not form necessary concentration difficulty in seed region.

The purpose of this utility model be to realize a kind of can with the gas supply valve of ignition mechanism interlock.

The utility model is made of jointly valve assembly and sensitive switch, the interlock dish is housed on the valve core rod of valve assembly, the interlock plate edge has the dish tooth, it can rotate with valve core rod, said sensitive switch is contained on the valve assembly, the tooth depth direction of the keying stroke directions of its open-close bond and dish tooth at grade, and open-close bond and said dish tooth mesh.

The utility model is contained in the supply air line of gas burner (kitchen range), and the output terminal of said sensitive switch is connected to electronic ignition device with lead.When desiring the burning head of ignition combustion device (as big duration and degree of heating gas cooker etc.), open steam supply valve and supply combustion gas to burning head, the interlock dish that cause is contained on the spool is to rotate synchronously thereupon, said dish tooth can be stirred the open-close bond that is engaged with continuously sensitive switch is repeatedly opened during rotation, be that sensitive switch can be in valve opening, constantly sending signal drives its firing head (as the electric plug equity) by electronic ignition device and produces a series of electrical spark, the electrical spark that enters synchronous generation of these and combustion gas can be lighted combustion gas at an easy rate, and ignition operation is easy and reliable.The utility model has been realized the synchronous interaction of fuel gas supply and electronic ignition, no longer has the combustion gas of not lighted during igniting and leaks, and Security is good.In a single day spool stops operating during the utility model, and sensitive switch stops to go up immediately to be done, and there is no unnecessary electrical spark and produces.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is Fig. 1 plan view.

Among the figure: 1-(combustion gas) steam outlet pipe, the 2-sensitive switch, the 3-open-close bond, 4-interlock dish, the 5-valve core rod, the 6-valve assembly, 7-(combustion gas) suction tude, the 8-valve handle, 9-coils tooth, 10-switch wire.

Embodiment: present embodiment is made up of Fig. 1 and Fig. 2.

As shown in the figure, sensitive switch (2) is contained in the last plane of valve assembly (6), and the open-close bond (3) of sensitive switch (2) stretches to valve core rod (5), and it opens and closes stroke directions also in that this side up; The keying stroke directions that is contained in interlock dish (4) and said open-close bond (3) on the valve core rod (5) at grade, and the engagement of the dish tooth (9) at its edge and open-close bond (3), the interlock dish (4) of present embodiment only towards sensitive switch (2) half dish tooth (9) arranged.Valve assembly (6) is contained in the gas inlet pipe road, its inlet, outlet respectively with (combustion gas) suction tude (7) and (combustion gas) steam outlet pipe (1) UNICOM.

The dish tooth (9) at said interlock dish (4) edge can be covered with the whole edge of interlock dish (4).

Claims

1, the gas valve of a kind of and ignition switch interlock, constitute by valve assembly (6) and sensitive switch (2), it is characterized in that on the valve core rod (5) of valve assembly (6) interlock dish (4) being housed, there is dish tooth (9) at interlock dish (4) edge, it can rotate with valve core rod (5), said sensitive switch (2) is contained on the valve assembly (6), the tooth depth direction of the keying stroke directions of its open-close bond (3) and dish tooth (9) at grade, and open-close bond (3) and said dish tooth (9) engagement.

2, as the said gas valve that links with ignition switch of claim 1, it is characterized in that described dish tooth (9) can not be covered with whole edges of said interlock dish (4).
