Description
Technical field
The utility model relates to a kind of leeway switching device, refers to a kind of leeway switch that plastic fixtures is housed especially.
Background technology
The leeway switch is as the main monitoring operating mode parts of gas-heating water heater, and its major function is for detection of the unobstructed situation of smoke pipe and the ruuning situation of blower fan.Blast switch is to adopt pressure point, epithelium and travel switch switch by two to constitute, and its key component is that adopting pressure point for two must have certain pressure differential, makes epithelium drive travel switch action, connection signal.For with wall hanging stove coupling, utilize theory in the fluid mechanics to design Venturi tube and gather negative pressure, the collection point of malleation is to gather total head with negative pressure under identical conditions, the fluctuation of blast is less relatively in this case; Blast switch belongs to the guard block of combustion system; for the safety of guaranteeing to burn plays crucial effect, so its action must be accurate, before fan operation; electric-control system must be confirmed the position of travel switch, only just can carry out next step operation in correct position.Existing leeway switch fixed support is generally the panel beating fixture, be to pass through thread connection, because the leeway switch is consumable accessory, so change frequent, this can cause the sliding tooth of support bracket fastened screwed hole, thereby cause the installation site of leeway switch to change, finally make disconnected closing (ON/OFF) the operating point parameter of leeway switch change, thereby make the leeway misoperation.
The utility model content
One, the technical problem that will solve
The purpose of this utility model is at existing in prior technology the problems referred to above, the spy provides a kind of leeway switch that plastic fixtures is housed, effectively solve the leeway switch because of the easy occurrence positions deviation of dismounting, thereby caused the defective of the control work that switch can not be good.
Two, technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of leeway switch that plastic fixtures is housed, and includes Switch main body, opening and closing tailgate and plastic fixtures; Above-mentioned Switch main body and opening and closing tailgate are connected, and above-mentioned opening and closing tailgate cooperates with the plastic fixtures clamping; Above-mentioned plastic fixtures is provided with buckle, above-mentioned buckle snap-action switch bonnet.
As optimization, above-mentioned plastic fixtures has for hard-wired screw on the rear end.
Three, the beneficial effects of the utility model
The leeway construction of switch that plastic fixtures is housed of the present utility model is simple, and easy accessibility can not be subjected to displacement, and guarantees that switch can works fine, and regular maintenance is comparatively convenient.
