Abstract
The utility model discloses a check valve, and particularly discloses a fireproofing check valve of a kitchen exhaust airway, which comprises a valve body and a check valve door, and is characterized by the following structure: a magnet for controlling the check valve door is arranged inside the valve body, and a valve seat is arranged at the bottom edge of the valve body; a fireproofing valve rod is arranged at the position in the inner side of the valve body edges, which is close to the check valve door, the fireproofing valve rod is provided with striking points at the tail end, and a fuse spring for pulling the fireproofing valve rod is arranged on a bearing seat of the valve rod. The fireproofing check valve has simple structure, convenient use and firmly fixing, combines a check valve and a fireproofing valve into a whole, effectively prevents the mutual interference of gas, odor and flame, and is suitable for being widely used in exhaust airways of residential houses.
Description
(1) technical field
The utility model relates to a kind of check valve, particularly a kind of kitchen air exhaust channel anti-fire check valve.
(2) background technique
High level or multi-storey building are provided with air exhaust channel, and the kitchen at each family is provided with the interface that communicates with this air exhaust channel in the building, the smoke-ejecting pipe of kitchen range hood links to each other with air exhaust channel by the outlet valve that is loaded on this interface, the oil smoke gas that cooker hood produces is pushed valve open, thereby oil smoke gas is concentrated discharge by the smoke exhaust of building from air exhaust channel.
The present this characteristics that are used for the outlet valve of air exhaust channel interface are, solved the problem that airflow direction in the original purging system complex structure, gas flue liquidates and pours in down a chimney easily when causing the smooth and smoke evacuation of smoke evacuation, but the fiery phenomenon of scurrying in the time of can not effectively organizing fire to take place is to cause the chain reaction of fire easily.
(3) summary of the invention
The utility model provides a kind of and both can prevent the taint of odour of collaborating in order to remedy the deficiencies in the prior art, can effectively stop the kitchen air exhaust channel anti-fire check valve of scurrying fire again.
The utility model is achieved by the following technical solution:
A kind of kitchen air exhaust channel anti-fire check valve comprises valve body and check valve, it is characterized in that: be provided with the magnet of control check valve in the described valve body, the valve body bottom edge is provided with valve seat; Inboard, valve body edge is pressed close to the check valve place and by stem bearing the fire prevention valve rod that end is provided with striking point is installed, and stem bearing is provided with the relief spring of traction fire prevention valve rod.
The utility model is installed the fire prevention valve rod on valve body, and valve seat is set, and makes valve body more firm with being connected of air draft road junction; Under the ventilating fan effect of kitchen ventilator, open during check valve work, by magnet it is held when not working, prevent that barometric pressure from refluxing, and pushes down oil smoke return-air and taint of odour.
In the utility model, the fire prevention valve rod be set to emphasis, when because of running into big fire, so that scurry fire, when temperature raises in the air exhaust channel, the striking point disconnection, the valve rod of preventing fires falls and drops on above the check valve, prevents that it from opening, and has stoped entering of big fire.
More excellent scheme of the present utility model is:
Further stable for ensureing that valve is installed, the relative both sides of valve seat are provided with by the fixing mounting spring card of retaining spring, and the jointing of valve seat and air exhaust channel is firmly fixing.
For preventing that flue gas or flare from entering from the jointing of valve seat and air exhaust channel, in the valve cup rim inboard seal ring is set, guarantee its sealing, prevent gas leakage.
The integral material of described anti-fire check valve is a stainless steel material.Stainless steel material has long-time corrosion protection, high temperature resistant, and indeformable behind the high temperature, indehiscent performance makes its easy accessibility, and is durable for a long time, is stained with greasy dirt if use for a long time, also is convenient to clean.
The utility model is simple in structure, and is easy to use, and collection check valve and fire-closing valve are one, and fixation effectively prevents to collaborate, taint of odour and scurry fire, is suitable for the extensive use of dwelling house air exhaust channel.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a main TV structure schematic representation of the present utility model;
Fig. 2 is a plan structure schematic representation of the present utility model;
Fig. 3 is the structural representation of looking up of the present utility model.
Among the figure, 1 valve body, 2 check valves, 3 magnet, 4 valve seats, 5 stem bearings, 6 striking points, 7 fire prevention valve rods, 8 relief springs, 9 retaining springs, 10 mounting spring cards, 11 seal rings.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises valve body 1 and check valve 2, is provided with the magnet 3 of control check valve 2 in the described valve body 1, and valve body 1 bottom edge is provided with valve seat 4; Inboard, valve body 1 edge is pressed close to check valve 2 places and by stem bearing 5 the fire prevention valve rod 7 that end is provided with striking point 6 is installed, and stem bearing 5 is provided with the relief spring 8 of traction fire prevention valve rod 7; Described valve seat 4 relative both sides are provided with the mounting spring card of fixing by retaining spring 9 10; Inboard, described valve seat 4 edge is provided with seal ring 11; The integral material of described anti-fire check valve is a stainless steel material.
Anti-fire check valve of the present utility model is installed on the reserved opening in air distribution road, kitchen, has been increased the convenience that the kitchen ventilator pipe is installed.
During kitchen ventilator work, anti-fire check valve is opened under the effect of its ventilating fan, is convenient to the discharge of oil smoke, and when not working, magnet holds check valve 2, stops it open, is convenient to flue gas in the separate row air channel.
When meeting with fire in the residential building, along with stretching of the intensity of a fire, the temperature in the air exhaust channel raises, the striking point 6 of fire prevention valve rod 7 ends disconnects, fire prevention valve rod 7 falls and drops on the check valve 2, and it is carried out rigid closing, and prevents that flue gas and big fire are in check valve 2 inlet chambers.
