Abstract
The utility model relates to a fire-proof check valve of exhaust pipe, which comprises a valve body, a valve slice and an fusible film; wherein, a filtering net is positioned in the air inlet of the valve body and the air outlet of the valve body is provided with a matching valve slice; the shaft at the inferior part of the valve slice is matched with the shaft sleeve at the inferior part of the air outlet of the valve body; a spring is socketed around the shaft; at the inferior part of the air outlet of the valve body a frame is arranged and fixed with an axis socketed by a compression spring; the hook pin fixed on the frame hitches the fusible film and the other end of the fusible film sockets on a compression spring. The utility model has the advantages of that: the valve is closed usually; the exhaust in a common exhaust pipe is unable to enter the chamber, but air current blows open the valve slice when the exhaust apparatus inside the chamber starts, allowing exhaust in the chamber to enter into the exhaust pipe; the fusible film is melted when the temperature inside the exhaust pipe reaches 70 Celsius degrees and the spring resets to close the valve, thereby preventing flame entering into the chamber.
Description
Technical field
The utility model relates to a kind of anti-fire check valve, particularly a kind of outlet pipe anti-fire check valve.
Background technique
Residential housing common exhaust pipe anti-fire check valve in the market, most employing check valves and two product mixes of fire-closing valve are used during design.
The model utility content
The purpose of this utility model provides a kind of outlet pipe anti-fire check valve that fire-closing valve and two kinds of functions of check valve unite two into one that possesses.
The technical solution of the utility model is a kind of outlet pipe anti-fire check valve of design, comprise valve body, valve block, fuse sheet, it is characterized in that: in the suction port on the valve body filter screen is arranged, the valve block that the air outlet of valve body has a slice and air outlet to work in coordination, the rotating shaft of valve block bottom cooperates with the axle sleeve of bottom, valve body air outlet, spring housing is in rotating shaft, one support is arranged at the bottom of valve body air outlet, fixing an axle on the support, compression spring sleeve is on axle, the hook pin that is fixed on the support hooks fuse sheet, and the other end of fuse sheet is enclosed within on the stage clip.
The utility model has the advantages that valve is in closed condition usually, in the common exhaust pipe waste gas can't inlet chamber in, but blowing valve block when the indoor exhaust device starts, indoor exhaust air enters outlet pipe, but temperature reaches Celsius 70 fusing of fuse sheet when spending in the outlet pipe, stage clip resets, throttle down, flame can't inlet chamber in.
Description of drawings
Accompanying drawing is a structural profile schematic representation of the present utility model,
Number is expressed as respectively among the figure: valve body 1, suction port 2, filter screen 3, catchment cup 4, valve block 5, air outlet 6, rotating shaft 7, axle sleeve 8, spring 9, support 10, axle 11, stage clip 12, fuse sheet 13, hook pin 14.
Embodiment
During use valve body 1 is fixed on the building exhaust pipes suction port, catchment cup 4 below, valve block 5 has rotating shaft 7 to cooperate support with axle sleeve 8, usual valve block 5 relies on the pressure of spring 9 that air outlet 6 is closed, waste gas in the common exhaust pipe can't inlet chamber in, but when the indoor exhaust device starts, waste gas enters from suction port 2, filter screen 3 is with waste gas filtering in the waste gas, separate, gas after the filtration overcomes spring 9 pressure and blows valve block 5 open, 6 enter common exhaust pipe from the air outlet, but temperature reaches Celsius 70 when spending in the common exhaust pipe, fuse sheet 13 fusing on support 10 hook pins 14, and the stage clip 12 that is enclosed within on the axle 11 resets, force valve block 5 sealing air outlets 6, flame can't inlet chamber in.
