Protrude to the suction port direction of Boilor check valve seat in the center portion of described valve block.
Beneficial effect of the present invention has:
Simple and practical, can utilize the self gravitation of valve block to realize the sealing of valve, after losing effect, the axis of guide spring at existing fire-preventing check valve valve block rear portion also makes valve block automatically to land to close and maintains to reach effect that valve block fire prevention and flue gas reflux, improve the working life of product, and can realize according to the opening degree of the power self regulating valve door of range hood, adjust exhaust air rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the explosive decomposition figure of diversion short tube of the present invention and internal structure.
Fig. 3 is the structural representation of turbine flap of the present invention.
Fig. 4 is that Boilor check valve seat closed condition of the present invention is faced structural representation.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in Figure 1, it includes Boilor check valve seat 1 the present invention, on Boilor check valve seat, have the Boilor check valve seat panel 13 parallel with smokejack tube wall 12, the front portion (being the right direction in Fig. 1) of Boilor check valve seat 1 arranges range hood hose connection, and the rear portion of Boilor check valve seat 1 is provided with diversion short tube 2.When valve installation is on oil-smoke expulsion pipe 12 time, Boilor check valve seat panel 13 parallels with the tube wall 12 of vertical row fume pipeline.The axis of guide 3 is installed in diversion short tube 2, the downward-sloping setting of the front end of the axis of guide 3 (being the A end in Fig. 1,2), with the angle α of Boilor check valve seat panel 13 be 30 °～85 °.The rear end (being the B end in Fig. 1,2) of the axis of guide 3 is connected with the rear portion of diversion short tube 2, or at the interior support that arranges of diversion short tube 2, location is realized in the axis of guide 3 rear ends by being connected with this support.On the axis of guide 3, be movably installed with valve block 4 sliding back and forth, in the time that range hood is not worked, due to Action of Gravity Field, valve block 4 can slide to the front end of the axis of guide 3 automatically, by the inlet hole sealing (as shown in Figure 4) of Boilor check valve seat 1, reach sealing and stop the object that in public chimney flue, oil smoke enters user room.In the time that range hood is worked, valve block 4 is backed down by flue gas, makes the flue gas can be from Boilor check valve seat 1 air inlet diversion short tube 2, then drains into public chimney flue from diversion short tube 2.The present invention can arrange turbine flap 5(as shown in Figure 3 at the leading flank of valve block 4), by turbine flap 5, can in the time that working, range hood make valve block 4 produce rotation, can improve exhaust smoke level.Preferably protrude to the suction port direction of Boilor check valve seat 1 in the center portion of valve block 4 of the present invention, contributes to improve the rotate effect of valve block 4, further improves smoke discharging effect.
When slidably reciprocating on the axis of guide 3 and rotate due to valve block 4, can contact with the axis of guide 3 outer walls and produce friction, for preventing their work of contact friction effect valve block 4, further improve the service behaviour of valve block 4, can copper pipe 10 be set in the center of valve block 4, valve block 4 is sleeved on the axis of guide 3 by copper pipe 10, and the internal diameter of copper pipe 10 is a bit larger tham the axis of guide 3 diameters.The axis of guide 3 preferably adopts stainless steel with valve block 4.
For reaching fire prevention object, the afterbody of the axis of guide 3 of the present invention has been installed temperature controlling device 6, this temperature controlling device 6 includes temperature control fuse piece 7, spring 8 and fixed claw 9, as shown in Figure 2, the rear portion of described fixed claw 9 in described valve block 4, makes spring 8 be compressive state by fixed claw 9 and the positioning action of temperature control fuse piece 7.In the time of excess Temperature, for example exceed 150 ℃, temperature control fuse piece 7 can fuse, and loses the positioning action to spring 8, and 8, spring can extend, and by fixed claw 9, valve block 4 is withstood to the air inlet through hole of sealing Boilor check valve seat 1.Fixed claw 9 has three pawl ends, the stability while guaranteeing to withstand valve block 4.
The upper half part of diversion short tube 2 of the present invention has smoke outlet 11, and its lower portion is sealed, and can strengthen the smoke discharging effect of diversion short tube 2.
Other the undeclared part the present invention relates to is same as the prior art.
