Abstract
A temperature control valve used for a fuel gas oven comprises a valve body, a valve core and a valve rod, wherein the valve body is provided with a valve rod passage, a valve chamber, an air inlet and a lateral air outlet which are communicated with each other. The fuel gas temperature control valve is characterized in that a temperature control valve seat is arranged on the valve chamber at one end opposite to the valve rod passage; the fuel gas temperature control valve further comprises a temperature control valve body, a gland bush, a temperature control component as well as temperature control package connected with the temperature control component; an air outlet is formed at one end of the temperature control valve body; the gland bush is matched with the temperature control valve seat; the temperature control component is fixedly connected with the temperature control valve body; the gland bush is in sliding fit with the temperature control component; a pressure spring is arranged between the gland bush and the temperature control component; and the temperature control valve body is connected with the valve body in a demountable manner. Due to the adoption of the structure, the temperature control package absorbs flame heat; and when an under burner for supplying fuel gas at the air outlet at end part is excess in temperature, the temperature control component expands under pressure, the gas between the gland bush and the temperature control valve seat becomes smaller, and the gas output of the fuel gas is reduced, thereby achieving the purpose of flame control.

Background technique
Present prior art, the safety valves for gas that a kind of gas burning roastor is used comprises valve body, spool, valve rod; Have valve stem passage, valve pocket, the suction port that is interconnected, the side air outlet of keeping supplying burner combustion, confession to descend the gas port that brings out of burner combustion on the valve body, suction port communicates with valve pocket.Existing problems are: the gas output of the combustion gas of control end air outlet automatically.
Summary of the invention
The purpose of this utility model is: the combustion gas thermostat valve that provides a kind of gas burning roastor to use, it is the gas output of control end air outlet effectively.
The utility model is achieved in that the combustion gas thermostat valve that a kind of gas burning roastor is used, and comprises valve body, spool, valve rod; Valve body has valve stem passage, valve pocket, suction port, the side air outlet that is interconnected, and it is characterized in that: the end that valve pocket is relative with valve stem passage is provided with the temperature control valve seat;
Also comprise a temperature control valve body, gland, temperature control assembly and the temperature control bag that is connected with the temperature control assembly, the temperature control valve body has one to bring out gas port; Gland cooperates with the temperature control valve seat, and temperature control assembly and temperature control valve body are fixedly connected, and gland and temperature control assembly are slidingly matched, and between gland and the temperature control assembly pressure spring is arranged, and the temperature control valve body detachably connects with valve body.
The combustion gas thermostat valve that described gas burning roastor is used, its special way is: have on the temperature control assembly pilot hole is arranged on a guide rod, the gland, guide rod inserts in the pilot hole and is slidingly matched.
The combustion gas thermostat valve that described gas burning roastor is used, its special way is: a guiding groove vertically that radially connects is arranged on the cylindrical shell of spool lower end; Gland has a connecting rod, and the axis of guide is radially arranged on the connecting rod, and connecting rod inserts in the cylindrical shell, the axis of guide cooperates with guiding groove, and connecting rod and cylindrical shell are slidingly matched.
The combustion gas thermostat valve that a kind of gas burning roastor of the utility model is used, owing to adopt such structure, temperature control wraps on the flame and absorbs heat, following burner when the air outlet, end for combustion gas, when the temperature of following burner was too high, the temperature control assembly was subjected to compression swelling, made the gap smaller between gland and the temperature control valve seat, reduce the combustion gas gas output, reach the purpose of control flame.

Fig. 3 is the plan view that the utility model gland cooperates with the gland seat.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, the combustion gas thermostat valve that a kind of gas burning roastor is used comprises valve body 1, valve gap 2, valve rod 3, spool 4; The valve stem passage, valve pocket, suction port 11, the side air outlet 12 that are interconnected are arranged on the valve body 1, and the suction port 11 on the valve body 1 directly is communicated with valve pocket, and the end that the valve pocket of valve body 1 is relative with valve stem passage is provided with temperature control valve seat 1A;
Also comprise a temperature control valve body 6, gland 7, temperature control assembly 8, the temperature control bag 5 that is connected with temperature control assembly 8, temperature control valve body 6 has one to bring out gas port 61; Gland 7 cooperates with temperature control valve seat 1A, temperature control assembly 8 is fixedly connected with temperature control valve body 6, gland 7 is slidingly matched with temperature control assembly 8, pressure spring (not drawing among the figure) is arranged between gland 7 and the temperature control assembly 8, temperature control bag 5 is connected with temperature control assembly 8 by the metal copper pipe, and temperature control valve body 6 detachably connects with valve body 1.
As shown in Figure 1, a guiding groove vertically that radially connects (not identifying among the figure) is arranged on the cylindrical shell 41 of spool 4 lower ends; Gland 7 has a connecting rod 71, and the axis of guide is radially arranged on the connecting rod 71, and connecting rod 71 inserts in the cylindrical shell 1, the axis of guide cooperates with guiding groove, and connecting rod 71 is slidingly matched with cylindrical shell 41.
As shown in Figure 3, there are a pilot hole arranged on a guide rod 81, the gland 7 (among the figure sign), guide rod 81 to insert in the pilot holes and be slidingly matched on the temperature control assembly 8.
The utility model is used hand rotation valve rod 3 in use, and valve rod 3 drives spools 4 and rotates, and spool 4 turns to a certain phase place, and combustion gas enters valve pocket, spool, side air outlet 12 by suction port 11, enters a burner; Spool 4 another phase place combustion gas is entered gap between valve pocket, spool, gland 7 and the temperature control valve seat 1A, temperature control valve body 6 by suction port 11 in, bring out gas port 61 and enter a burner.With bring out the burner that gas port 61 is connected, when temperature is too high, the temperature control bag transfers the pressure to temperature control assembly 8, make temperature control assembly 8 be subjected to compression swelling, the gap smaller of gland 7 and temperature control valve seat 1A, gas output diminishes, when the temperature control bag is delivered to pressure on the temperature control assembly 8 when reducing, temperature control assembly 8 shrinks, and gland 7 becomes big with the gap of temperature control valve seat 1A, and the quantitative change of giving vent to anger is big.Reach the requirement of control temperature.
