Abstract
The utility model relates to a firedoor control switch of combustion furnace, including a firedoor, a furnace shell provided with a sheath-type fixed holder and a lower bracket and a travel switch, and a main lever supported by the lower bracket with the top end passing through the sheath-type fixed holder, a toggle plate and a cam mounted on the main lever. The utility model which has simple structure, high sensitivity and reliabilty is capable of implementing the interlock between the firedoor open and the air-blower operation, namely when the firedoor is open, the air-blower is cut off and stopped working, thereby preventing outer spray of gas in furnace.
Description
Technical field
The utility model belongs to the combustion apparatus field, relates to a kind of fire door gauge tap of combustion furnace.
Background technology
At present, when boiler positive pressuring combustion, can occur not turning off the faulty operation that blower switch is just opened fire door usually,, cause the outer spray of inner flue gas of the stove to cause personnel's burning accident because existing fire door does not have the interlocked control switch.
Summary of the invention
The purpose of this utility model is to solve above-mentioned prior art problem and provides a kind of simple in structure, highly sensitive, safe and reliable combustion furnace fire door gauge tap.
The technical solution adopted in the utility model: a kind of combustion furnace fire door gauge tap, comprise fire door, furnace shell, its furnace shell is provided with shell type holder and subiculum, and travel switch is installed, mobile jib is supported by subiculum, and the shell type holder is passed in the upper end, and buckle and cam are installed on the mobile jib.
Described buckle is buckled on the fire door.
Described travel switch contacts with cam or throws off.
The utility model is provided with the interlocked control switch, can realize the interlocking between door opened and the air blast work, promptly when door opened, the air blast outage quits work, and avoids the generation of the outer spray accident of inner flue gas of the stove, and the utility model is simple in structure, highly sensitive, safe and reliable, easy for installation.
Description of drawings
Fig. 1 is the front view of the utility model structural representation;
Fig. 2 is the vertical view of the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Consult Fig. 1, shown in Figure 2, a kind of combustion furnace fire door gauge tap mainly comprises shell type holder 1, mobile jib 2, buckle 3, subiculum 4, fire door 5, furnace shell 6, cam 7, travel switch 8 etc.; Be vertically installed with shell type holder 1 and subiculum 4 in the position up and down in furnace shell 6 positive sides, it is interior by its supporting that mobile jib 2 lower ends are arranged on subiculum 4, and shell type holder 1 is passed in the upper end; Buckle 3 and cam 7 are installed on mobile jib 2, and buckle 3 one ends are buckled in fire door 5 edges; Travel switch 8 is installed in furnace shell 6 end faces, contacts with cam 7 or throws off.
Operation principle of the present utility model: when needs are opened fire door 5, removed buckle 3 earlier, buckle 3 interlock mobile jibs 2 rotate simultaneously, and 7 swings of mobile jib 2 rotating band moving cams make cam 7 throw off travel switch 8, and this moment, travel switch 8 deenergizations quit work air blast; Drive mobile jib 2 in the time of by lower pinch plate 3 and make cam 7 contacting travel switches 8 connect power supplys, make air blast work.
