Abstract
The utility model relates to a dividing valve of an external ignition type fuel gas safety protective valve of a flameless combustion infrared oven, which is characterized by comprising a dividing valve body, a valve rod moving in a reciprocating way along a straight line, a valve core and a reset spring; the dividing valve body is provided with a gas inlet passage, a valve rod cavity and a valve core cavity; the valve core is arranged at one end of the valve rod, the other end of the valve rod and the valve rod cavity are in gas seal, and the valve core is matched with a valve core seat; a guide rod arranged at the other end of the valve rod is matched with a guide hole arranged on the dividing valve body; one end of the reset spring is matched with a spring seat on the valve core, the other end of the reset spring is matched with a washer, and the washer is fixed and gas sealed by a flange; the flange is connected with a gas tube of a small fire igniter, and the valve rod cavity is provided with a gas outlet passage to be communicated with a combustor; a prying piece pivoted on the dividing valve body is matched with the guide rod. The ignition mode of an infrared combustor is changed from direct ignition inside or outside the cavity by an electronic ignition needle into open fire ignition outside the cavity, thereby detonation is prevented, and the igniting rate is ensured. The ignition needle and the infrared combustor are separated, thereby the service life is prolonged, and the safety hidden danger is eliminated.
Description
Technical field
The utility model relates to the safety valves for gas of infrared burner, especially a kind of flow divider that cooperates with the fuel safety protecting valve.
Background technology
Present prior art, a kind of gas furnace safety protective valve.When being used for (infrared ray) burner, the escape pipe of valve body communicates with the inner chamber of infrared burner, and the electronic ignition pin is installed in the inner chamber of infrared burner, lights a fire or is installed in outside the infrared burner chamber in the chamber and light a fire.Existing problems are: because piezoelectric ceramics does the time spent and hit high-voltage spark in moment, just can light during air mixture that combustion gas that must be in nozzle is spurted into burner and air are mixed into debita spissitudo; Spray combustion gas overlong time to the burner if open the air valve nozzle, gas concentration is too high in the mist of burner, and deflagration phenomenon easily takes place during igniting, has potential safety hazard; Otherwise opening the air valve nozzle, to spray combustion gas too short to the burner time, and the gas concentration in the burner is too low, and piezoelectric ceramics is made the high-voltage spark that the time spent hits in moment and put not burner, can not finish normal working performance.
Summary of the invention
The purpose of this utility model is: the flow divider of the external ignition type gas safety protective valve of a kind of flameless combustion infrared heating heating furnace is provided, and it can not only finish normal working performance, and has eliminated potential safety hazard.
The utility model is achieved in that the flow divider of the external ignition type gas safety protective valve of a kind of flameless combustion infrared heating heating furnace, and its special character is: comprise shunting valve body, the valve rod, spool and the back-moving spring that move along linear reciprocation; The shunting valve body has inlet channel, valve-rod cavity and spool chamber; An end, the valve rod other end that spool is positioned at valve rod have packing holder, and one first sealing ring is arranged on the packing holder; First sealing ring and valve-rod cavity hermetic seal, spool cooperates with valve core case; Have the end of the valve rod of packing holder that one guide post is arranged, guide post cooperates with the pilot hole of shunting on the valve body;
Back-moving spring one end is installed on the spring base that is positioned on the spool, and there is ring platform in an outlet side of spool chamber, has a packing ring, the back-moving spring other end to cooperate with packing ring on the interior ring platform, and a flange is fixing and hermetic seal with packing ring;
Flange is connected with little fiery device for igniting tracheae, and packing holder has an outlet passageway to communicate with burner with valve-rod cavity between the spool; Articulate a sled part on the shunting valve body, the sled part cooperates with guide post.
The flow divider of the external ignition type gas safety protective valve of described a kind of flameless combustion infrared heating heating furnace, its special character is: at spool and valve rod intersection one cannelure is arranged, have one second sealing ring to cooperate hermetic seal with valve core case in the cannelure.
The flow divider of the external ignition type gas safety protective valve of a kind of flameless combustion infrared heating heating furnace of the utility model, inlet channel and the escape pipe on the fuel safety protecting valve on the shunting valve body are connected.Because adopt such structure, when the knob of rotatable gas safety protective valve, the fuel safety protecting valve is opened, combustion gas enters infrared burner through fuel safety protecting valve, flow divider; Continue the rotation knob again, knob drives the switch arm rotation, and switch arm prizes the sled spare of flow divider, the sled part moves valve rod, and spool is lifted off a seat, and a small amount of combustion gas enters little fiery device for igniting, the electronic ignition pin mark fires little fiery device for igniting, and little fiery device for igniting naked light is lighted infrared burner; After lighting infrared burner, when the ineffective power of guide post, under the effect of back-moving spring, valve rod is moving to travelling backwards, and valve core reset cuts off little fiery device for igniting.Make infrared burner by in the chamber or out-cavity electro igniting pin directly light and become naked light in the chamber outside and light, prevented detonation, guaranteed lighting rate, the pin of lighting a fire separates with infrared burner, has prolonged service life, has eliminated potential safety hazard.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the flow divider of the external ignition type gas safety protective valve of a kind of flameless combustion infrared heating heating furnace comprises shunting valve body 1, the valve rod 2, spool 3 and the back-moving spring 5 that move along linear reciprocation; Shunting valve body 1 has inlet channel 11, valve-rod cavity 12 and spool chamber 13; An end, valve rod 2 other ends that spool 3 is positioned at valve rod 2 have packing holder 21, and one first sealing ring 41 is arranged on the packing holder 21; First sealing ring 41 and valve-rod cavity 12 hermetic seals, spool 3 cooperates hermetic seal with valve core case 131; Have the end of the valve rod 2 of packing holder 21 that a guide post 22 is arranged, guide post 22 cooperates with the pilot hole 16 of shunting on the valve body 1;
Back-moving spring 5 one ends are installed on the spring base that is positioned on the spool 3, and there is ring platform 132 in an outlet side of spool chamber 13, has a packing ring 6, back-moving spring 5 other ends to cooperate with packing ring 6 on the interior ring platform 132, and a flange 7 is with packing ring 6 fixing and hermetic seals;
