Abstract

The utility model discloses a check valve used in a high-floor and multi-floor domestic smoke gas centralized discharging system, which comprises a valve body pipe which comprises an air inlet arranged on one end and an air outlet arranged on the other end, wherein the air inlet is provided with a non-retaining sheet which is coincident with the end surface. A filter screen is arranged on the end surface of the air inlet, the lower end of an oil filter screen is provided with an oil collecting cup, the positive center of the bottom of the valve body pipe is vertically provided with a supporting stand, a sealed valve core pipe is fixed on the center of the supporting stand, a force-back spring is arranged in the center hole of the sealed valve core pipe, and a draw rod is connected in the center hole in series, one end of the draw end which is closed to the air inlet is provided with a fire-proof piece and a locking spring, and the other end of the draw rod is fixed on the center of the non-retaining sheet through a screw cap. The oil filter screen is moveably connected, and the oil collecting cup is moveably connected, and the locking spring is arranged between the fire-proof piece and a non-retaining screw cap. The check valve has the functions of inhibiting smoke gas from tainting by odour and reversely pouring, and overcoming adhesion of oily soil, and effectively preventing fire hazards.

Description

The check valve of a kind of high level, multiple dwelling fume centralized releasing system

Technical field

The utility model relates to a kind of fume emission device, relates in particular to a kind of anti-tank switching, anti-taint of odour, frpf multiple dwelling fume centralized releasing system.

Background technique

The shared kitchen of tradition check valve for flue, in the valve member air outlet, depending merely on check sheet on the eccentrically weighted shaft closes air outlet, time from gravity and has grown, eccentrically weighted shaft has sticked greasy, produced very big resistance, check sheet can not normal switch be used, and flue gas pours in down a chimney, the taint of odour phenomenon so produced, and has brought inconvenience in daily life for resident family.

The utility model has passed through development for many years, and the anti-of resident family's kitchen common flue poured in down a chimney, prevents that taint of odour, fire prevention have very strong specific aim, can effectively prevent, and particularly when fire alarm occurring, can cut off spreading of the intensity of a fire in the very first time.

The model utility content

In order to overcome defective of the prior art, the utility model provides a kind of anti-tank switching, anti-taint of odour, frpf multiple dwelling fume centralized releasing system.

The technological scheme that its technical problem that solves the utility model adopts is: the check valve of a kind of high level, multiple dwelling fume centralized releasing system, comprise that a conduit, this conduit comprise the suction port of being located at an end, and an air outlet of being located at the other end, this air outlet establishes one and the check sheet that matches of end face.

This suction port end is established one and is crossed oil screen, and a catchment cup is established in this lower end of crossing oil screen; The bottom centre of this conduit is vertically established a support, the center fixation one draught excluder core barrel of this support, establish a return spring in the center hole of this draught excluder core barrel, and be connected in series a pull bar, this pull bar is established fire prevention part and a locking spring near the suction port end, this pull bar the other end by fixed by nut in described check sheet center.

This crosses oil screen for flexibly connecting, and this catchment cup is for flexibly connecting, and this locking spring is located between this a fire prevention part and the retaining nut.

The beneficial effects of the utility model are: prevented that flue gas pours in down a chimney, taint of odour; Effectively prevented disaster hidden-trouble; Overcome the adhesion of greasy dirt.

Description of drawings

Fig. 1 is a longitudinal section view of the present utility model.

Wherein:

1, conduit 2, mistake oil screen 3, catchment cup 4, support 5, draught excluder core barrel 6, retaining nut 7, locking spring 8, pull bar 9, fire prevention part 10, positioning screw cap 11, return spring 12, check sheet 13, nut 14, common duct 15, suction port 16, air outlet

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

The check valve of a kind of high level, multiple dwelling fume centralized releasing system comprises that a conduit 1, this conduit 1 comprise the suction port 15 of being located at an end, and an air outlet 16 of being located at the other end, and this air outlet 16 establishes one and the check sheet 12 that matches of end face.

These suction port 15 ends are established one and are crossed oil screen 2, and a catchment cup 3 is established in this lower end of crossing oil screen 2; The bottom centre of this conduit 1 is vertically established a support 4, the center fixation one draught excluder core barrel 5 of this support 4, establish a return spring 11 in the center hole of this draught excluder core barrel 5, and be connected in series a pull bar 8, this pull bar 8 is established a fire prevention part 9 and a locking spring 7 near suction port 15 1 ends, and these pull bar 8 the other ends are fixed in described check sheet 12 centers by nut 13.

The described oil screen 2 of crossing is for flexibly connecting, and described catchment cup 3 is for flexibly connecting, and described locking spring 7 is located between this a fire prevention part 9 and the retaining nut 6.

When the kitchen fume machine is opened by resident family, powerful air draft oil smoke gas by kitchen ventilator carries out the separation of oil smoke gas from conduit 1 suction port 15 by crossing oil screen 2, waste oil is flowed in the catchment cup 3, at this moment check sheet 12 is opened automatically, the flue gas that will give up is discharged, and when closing exhaust, check sheet 12 resets it by return spring 11 pushing drawing rods 8, seal exhaust outlet, effectively prevention is given up, and flue gas pours in down a chimney, taint of odour.

The kitchen stove, the practical improper easy generation condition of a fire, rise to 70 ℃ time fire prevention part dissolves immediately when the condition of a fire has just begun temperature, the locking spring 7 that closes flicks rapidly, bullet retaining nut 6 on pull bar 8 is closed check sheet 12 by force, block the relief opening of fire layer, in the very first time, played the effect of fire prevention partition.

This product adopts the aluminum alloy material structure reasonable, durable, and oil screen 2, catchment cup 3 can be dismantled regular cleaning excessively.The groundwork part all designs in draught excluder core barrel 5 chambeies, makes pull bar 8 work that moves back and forth, and can avoid the greasy dirt infiltration, influences the regular event of check sheet 12, and effectively overcome traditional check valve 12 and clung by greasy dirt, and affected shortcoming.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
