Abstract

The utility model provides a complete general butterfly wing range hood check valve, it includes the valve body in band -pass cigarette hole, the center, left and right semicircle valve plate and sealing strip, characterized by: the valve body is the casing pegs graft through annular interface with lower casing and constitutes, sets up in inferior valve internal logical cigarette hole and uses the center as the semi -circular sealed frame of boundary to the both sides symmetric distribution, and the circular sealed frame of two halves has and follows the center and to the slope of both sides rise, lead the oil groove in the outer fringe setting of the circular sealed frame of two halves simultaneously, at the fixed arris body wind guide of side that facings the wind of center, the general reducing circle of logical mouth in -connection Z type of casing under. The utility model has the advantages that the last greasy dirt of sealed rubber ring is difficult for saving bit by bit, and the valve plate is difficult for the adhesion, and the switch is light, and sealed effectual simultaneously, inlet connection department realizes generally, and the installation is swift, convenient, easy dismouting.

Description

All-purpose wing smoke exhaust check (non-return) valve

Technical field

This utility model belongs to a kind of kitchen discharged lampblack check (non-return) valve, particularly a kind of all-purpose wing smoke exhaust check (non-return) valve。

Background technology

A kind of shared discharge flue being to connect up/down perforation of each family kitchen discharged lampblack outlet of present building resident, another kind is directly facing to outdoor, in order to prevent return of smoke and smell or cold wind from driving in the wrong direction, all exports at mist extractor and installs lampblack-discharging check valve。Total flue is caused resistance when opening by the valve plate existed to solve original monolithic valve board structure check (non-return) valve, in flue, malleation is excessive, the problem being not closed completely, the applicant have developed " Antiseize omniseal shared flue check valve " (patent No.: 200920288390.1) and " Anti-sticking full-sealing lampblack-discharging check valve " (patent No.: 201020666301.5), there is good sealing effect, switch the advantages such as light。By using practice, it has been found that still Shortcomings, e.g., when oil extraction is more, time on the more O-ring seal being attached to below valve plate of greasy dirt, valve plate is adhered on O-ring seal, opens heavier, discharges fume smooth and easy not。

Summary of the invention

The purpose of this utility model is to provide a kind of all-purpose wing smoke exhaust check (non-return) valve, and on O-ring seal, greasy dirt is not easily saved bit by bit, and valve plate is adhesion not easily, and easily, good sealing effect simultaneously, entrance point junction realizes general switch, quick for installation, convenient, it is easy to dismounting。

The purpose of this utility model is achieved by the following technical solution: it includes the valve body with exhaust hole, center, left and right semicircle valve plate and sealing strip, it is characterized in that: valve body is that upper shell and lower house are consisted of annular interface grafting, exhaust hole in lower house arranges the semicircle sealing frame symmetrical with center for boundary to both sides, two halves circle sealing frame has the gradient risen from center to both sides simultaneously, and the outer rim in two halves circle sealing frame arranges oil guide groove；The fixing rib body air guide member of windward side at center, connects the general diameter-varying ring of Z-type in the smoke hatch of lower house。

Effect of the present utility model is: on O-ring seal, greasy dirt is not easily saved bit by bit, and valve plate is adhesion not easily, and easily, good sealing effect simultaneously, entrance point junction realizes general switch, quick for installation, convenient, it is easy to dismounting。

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model (from the port of export)。

Fig. 2 is Fig. 1 cross-sectional view。

Detailed description of the invention

Seeing Fig. 12, the concrete structure of embodiment 1 is as follows: has the valve body of exhaust hole and is upper shell 8 and lower house 7 is consisted of annular interface grafting, and be respectively provided with dop and hole clipping 14 on two housings, makes axial restraint between the two。Circular exhaust hole and center 3 are set by prior art in lower house 7, exhaust hole arranges the semicircle sealing frame 6 symmetrical with center 3 for boundary to both sides, simultaneously two halves circle sealing frame 6 rises the gradient of 10 °-15 ° from center to both sides, so that greasy dirt not easily saved bit by bit by the sealing strip 9 in two halves circle sealing frame 6；Outer rim in two halves circle sealing frame 6 arranges oil guide groove 12；Left and right semicircle valve plate 4 is vertically connected with on draw-in groove by what upper and lower bearing pin 1 was rotatably connected on center 3, when left and right semicircle valve plate 4 is fastened in two halves circle sealing frame 6, has the gradient rising 10-15 ° from center to both sides equally。The card article 11 and the sealing strip 9 that assemble card article 11 and sealing strip 9(assembling on the both sides of two halves circle sealing frame 6 and center 3 are existing structure), seal when making left and right semicircle valve plate 4 close；Windward side at center 3 fixes rib body air guide member 13 by latch jack, to reduce exhaust resistance。The steel wire torsion spring 5 of the left and right semicircle valve plate 4 of connection closed after center 3。Annular inserting groove is set in the front end of upper shell 8, for the grafting soft cylinder of smoke evacuation；In the smoke hatch of lower house 7, connect the general diameter-varying ring 10 of Z-type, adapt to the installation needs of different oil extraction mouth。

Claims

1. an all-purpose wing smoke exhaust check (non-return) valve, it includes the valve body with exhaust hole, center, left and right semicircle valve plate and sealing strip, it is characterized in that: valve body is that upper shell and lower house are consisted of annular interface grafting, exhaust hole in lower house arranges the semicircle sealing frame symmetrical with center for boundary to both sides, and two halves circle sealing frame has the gradient risen from center to both sides simultaneously, and the outer rim in two halves circle sealing frame arranges oil guide groove；The fixing rib body air guide member of windward side at center, connects the general diameter-varying ring of Z-type in the smoke hatch of lower house。

2. all-purpose wing smoke exhaust check (non-return) valve according to claim 1, is characterized in that: two halves circle sealing frame has the gradient 10 °-15 ° risen from center to both sides。
