　　本发明的动作过程如下：The action process of the present invention is as follows:
　　1、完全关闭状态1, completely closed state
　　见图1、进气口有燃气进入，但是进气腔与阀芯腔之间由电磁阀密封片切断气流，阀芯腔与出气储存腔、长明火出气口之间由阀芯切断气流，出气储存腔与出气腔之间由第一连接部件切断气流，小流量通道由小流量密封部件切断气流。See Fig. 1. There is gas entering at the air inlet, but the air flow is cut off between the air inlet chamber and the valve core chamber by the solenoid valve sealing piece. The air flow is cut off between the valve core chamber and the air outlet storage chamber and the long open flame outlet port. The air flow is cut off between the storage chamber and the air outlet chamber by the first connecting member, and the small flow passage is cut off by the small flow sealing member.
　　2、接通长明火出气口2. Connect the open flame outlet
　　见图2、操作手动开关装置，手动开关装置控制阀芯逆时针转动50度，接通阀芯腔与长明火出气口；同时打开电磁阀，电磁阀带动电磁阀密封片动作，接通进气腔与阀芯腔；于是，接通长明火出气口。图中的G表示燃气。As shown in Figure 2, the manual switch device is operated. The manual switch device controls the valve core to rotate 50 degrees counterclockwise, and opens the valve core cavity and the open flame outlet; at the same time, the solenoid valve is opened, the electromagnetic valve drives the solenoid valve seal to act, and the intake air is turned on. The cavity and the spool cavity; thus, the long open flame outlet is connected. G in the figure indicates gas.
　　3、接通出气储存腔3, turn on the gas storage chamber
　　见图3、操作手动开关装置，手动开关装置控制阀芯逆时针再转动90度，接通阀芯腔与出气储存腔。图中的G表示燃气。See Figure 3. Operation of the manual switch device. The manual switch device controls the spool to rotate 90 degrees counterclockwise to open the spool chamber and the outlet storage chamber. G in the figure indicates gas.
　　此时进入自动控温状态，出气储存腔与出气腔的导通由第一连接部件、第二连接部件、第三连接部件、小流量密封部件完成。At this time, the automatic temperature control state is entered, and the conduction between the air outlet storage chamber and the air outlet chamber is completed by the first connecting member, the second connecting member, the third connecting member, and the small flow sealing member.
　　4、接通小气流4, turn on the small airflow
　　开关动力元件是探测到环境温度比设定温度低时，才启动燃气安全阀工作，以保证环境温度维持到一定的水平。当开关动力元件探测到环境温度为设定温度上限时，出气储存仓处于关闭状态，出气储存仓与出气仓不导通。When the switching power component detects that the ambient temperature is lower than the set temperature, the gas safety valve is activated to ensure that the ambient temperature is maintained at a certain level. When the switching power component detects that the ambient temperature is the upper limit of the set temperature, the outlet storage bin is closed, and the outlet storage bin and the outlet bin are not conductive.
　　见图4，当开关动力元件探测到环境温度为小于设定温度上限5度时，开关动力元件作收缩动作，带动第三连接部件往下运动，第三连接部件不再顶住弹簧片，使弹簧片瞬间失去作用力，迅速作出回弹动作；弹簧片不再顶住小流量密封部件，小流量密封部件下落，小流量密封部件迅速失去密封作用，小流量通道被打开，由于第二连接部件内部与出气腔相通，所以小气流连接到出气口，使出气口的流量为设计值的15%状态（15%的状态是为产品使用不同的气源（石油气、天然气、人工气）及配置于不同的机型而设定的，由于产品使用不同气源及机型时其所得的初始热值的要求会有不同，15%状态设计为可调，使得产品能广泛运用于不同机型的燃气取暖器及燃气烤箱上，从而普及）。图中的G表示燃气。Referring to FIG. 4, when the switching power component detects that the ambient temperature is less than 5 degrees of the upper limit of the set temperature, the switching power component performs a contracting action to drive the third connecting component to move downward, and the third connecting component no longer bears against the spring piece. The spring piece loses its force instantaneously and quickly makes a rebound action; the spring piece no longer resists the small flow sealing part, the small flow sealing part falls, the small flow sealing part quickly loses the sealing effect, and the small flow passage is opened due to the second connecting part The inside is connected to the outlet chamber, so the small air flow is connected to the air outlet, so that the flow rate of the air outlet is 15% of the design value (15% state is to use different gas sources (LPG, natural gas, artificial gas) and configuration for the product. Set for different models, the initial heating value requirements of the product will be different due to different gas sources and models. The 15% state is designed to be adjustable, making the product widely used in different models. Gas heaters and gas ovens, so popular). G in the figure indicates gas.
　　此时，第一连接部件、第二连接部件仍然受主密封弹簧的作用力，处于完全密封状态，主气流并未打开，所以燃气安全阀只是小火在燃烧。At this time, the first connecting member and the second connecting member are still subjected to the force of the main sealing spring, and are in a completely sealed state, and the main airflow is not opened, so the gas safety valve is only a small fire burning.
　　5、接通主气流5, turn on the main airflow
　　见图5，开关动力元件探测到环境温度仍然未达到设定温度的最低值时，开关动力元件继续作收缩动作，带动第三连接部件继续往下运动；由于第三连接部件与第二连接部件是活动连接，第三连接部件继续往下运动0.5mm后，这时开始带动第二连接部件往下运动，第二连接部件带动第一连接部件往下运动，从而第一连接部件不再封住出气储存腔与出气腔之间，完全打开主流量通道，主气流通过出气口排出，实现大火燃烧。图中的G表示燃气。Referring to FIG. 5, when the switching power component detects that the ambient temperature has not reached the minimum value of the set temperature, the switching power component continues to perform the contracting action, and the third connecting component continues to move downward; because the third connecting component and the second connecting component Is the movable connection, after the third connecting member continues to move downward by 0.5 mm, then the second connecting member is driven to move downward, and the second connecting member drives the first connecting member to move downward, so that the first connecting member is no longer sealed. Between the outlet storage chamber and the outlet chamber, the main flow passage is completely opened, and the main air flow is discharged through the air outlet to achieve large fire combustion. G in the figure indicates gas.
　　反之，当温度上升时，开关动力元件作膨胀运动，首先第一连接部件、第二连接部件受主密封弹簧的反弹作用力，往上运动，将出气储存腔与出气腔之间关闭；出气储存腔与出气腔之间关闭后。开关动力元件仍然在膨胀，使第三连接部件继续上升0.5mm后，顶上弹簧片，使弹簧片在瞬间弹起小流量密封部件，小流量密封部件封住小流量通道，从而使阀体自动关闭。Conversely, when the temperature rises, the switching power element performs an expansion motion. First, the first connecting member and the second connecting member are subjected to the rebounding force of the main sealing spring, and move upward to close the air storage chamber and the air outlet chamber; After closing between the chamber and the outlet chamber. The switching power component is still expanding, so that the third connecting component continues to rise by 0.5 mm, the spring piece is placed on top of the spring piece, so that the spring piece springs up the small flow sealing component, and the small flow sealing component seals the small flow passage, thereby automatically the valve body shut down.
