Abstract
The invention discloses a fire-proof check valve for discharging oil fume and capable of automatically adjusting air exhaust volume. The valve comprises a valve body. A valve flap is arranged in the valve body; the valve flap is sleeved on a fixed mandrel rotatably; a front spring and a back spring are sleeved on the mandrel; l a valve flap lifting piece sleeved on the mandre is arranged between the front spring and the back spring and connected with a fixed fuse link; an oil fume through-hole which is communicated with an oil fume channel and opened and closed by forward and backward movements of the valve flap is arranged on the valve body. The check valve has the advantages of reasonable structure and good working performance. When an oil fume machine is not in the working state, the valve flap closes the channels of the valve body; when the oil fume machine is in the working state, the valve flap is driven by the oil fume to rotate and move backwards to partially or completely open the oil fume through-hole, meanwhile, the centrifugal effect is acted on the oil fume to enhance working effects. The open degree of the oil fume through-hole is related with the power of the oil fume machine.
Description
Technical field
The present invention relates to a kind of fire-preventing check valve.
Background technique
Existing fire-preventing check valve, complex structure, service behaviour is undesirable, can not increase or reduce the size of cooking-fume discharging pore along with the kitchen ventilator watt level, and the adjusting function of cooking-fume discharging tolerance is poor.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the automatic adjusting exhaust air rate oil extraction flue gas fire-preventing check valve of favorable working performance.
Technical solution of the present invention is:
A kind of automatic adjusting exhaust air rate oil extraction flue gas fire-preventing check valve, comprise valve body, flap is set in the valve body, it is characterized in that: flap is and is sleeved on turnably on the fixing mandrel, suit front spring, rear spring on the mandrel, the flap head part that is sleeved on the mandrel is set between front spring and rear spring, and the flap head part is connected with the fuse link of fixing; The oil smoke vent hole that communicates, opened and closed by moving forward and backward of flap with fume pipeline is set on the valve body.
Flap comprises plate body, and the blade of projection is set on the plate body.
The length of oil smoke vent hole on fore-and-aft direction is greater than the thickness of flap.
The present invention is rational in infrastructure, favorable working performance; When kitchen ventilator was not worked, flap was in the valve channel closing state; During kitchen ventilator work, the moving flap rotation of the oil smoke band of gas is also mobile backward, and the oil smoke vent hole is partly or entirely opened, and simultaneously oil smoke is played centrifugal action, increases the work effect.The aperture of oil smoke vent hole is relevant with kitchen ventilator power.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the exploded view of Fig. 1.
Fig. 3 is the another kind of use of the present invention phase diagram.
Embodiment
A kind of automatic adjusting exhaust air rate oil extraction flue gas fire-preventing check valve, comprise valve body 1, flap 2 is set in the valve body, flap is and is sleeved on the fixing mandrel 3 turnably, suit front spring 4, rear spring 5 on the mandrel, the flap head part 6 that is sleeved on the mandrel is set between front spring and rear spring, and the flap head part is connected with the fuse link of fixing 7; The oil smoke vent hole 8 that communicates, opened and closed by moving forward and backward of flap with fume pipeline is set on the valve body.
Flap comprises plate body, and the blade 9 of projection is set on the plate body.The length of oil smoke vent hole on fore-and-aft direction is greater than the thickness of flap.
When temperature was too high, fuse link was fused, and the flap head part moves forward under the effect of rear spring 5, and flap is withstood, and valve cuts out.
