Abstract
The utility model discloses an oil fume discharge fireproofing check valve with a function of automatic air discharge quantity adjustment. The check valve comprises a valve body, wherein a valve clack is arranged inside the valve body; the valve clack is sleeved on a fixed core shaft in a rotational mode; a front spring and a rear spring are sleeved on the core shaft; a valve clack top piece which is sleeved on the core shaft is arranged between the front spring and the rear spring; the valve clack top piece is connected with a fixed fusing sheet; and an oil fume through hole which is communicated with a fume pipeline and is opened or closed along with the forward and backward movement of the valve clack is arranged on the valve body. The check valve is reasonable in structure and good in working performance; when a range hood does not work, the valve clack is at the state of closing a valve body channel; when the range hood works, the valve clack is driven by the fume to rotate and move backwards so as to partially or completely open the fume through hole, and meanwhile the fume is subjected to centrifugal action, so that the working effect is improved. The opening degree of the fume through hole is related to the power of the range hood.
Description
Technical field
The utility model 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.
The model utility content
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the automatic adjusting exhaust air rate oil extraction flue gas fire-preventing check valve of favorable working performance.
The technical solution of the utility model 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 the fixing mandrel suit front spring, rear spring on the mandrel turnably; Be provided with between front spring and rear spring and be sleeved on the flap head part on the mandrel, the flap head part is connected with fixing fuse link; 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 protruding blade 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 utility model 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 moved backward, and the oil smoke vent hole is partly or entirely opened, and simultaneously oil smoke is played centrifugal action, increases work.The aperture of oil smoke vent hole is relevant with kitchen ventilator power.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is the exploded view of Fig. 1.
Fig. 3 is the another kind of user mode figure of the utility model.
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, and flap is and is sleeved on the fixing mandrel 3 turnably, suit front spring 4, rear spring 5 on the mandrel; Be provided with between front spring and rear spring and be sleeved on the flap head part 6 on the mandrel, the flap head part is connected with fixing fuse link 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 protruding blade 9 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.
