The soft cover valve comprises a valve sleeve and a valve soft cover. A valve soft cover frame is corresponding to an exhaust outlet (18) in the valve sleeve, the vertical section of the soft cover frame is S-shaped, a rainproof cloth (1) is fixed on the soft cover frame in a bonding manner, one side of the soft cover frame is connected with a spring pressing plate (9), circular shafts (6) are arranged at the two sides of the spring pressing plate, a spring fixing bolt (10) is arranged on the spring pressing plate, and a spring (4) is fixed by the spring fixing bolt; the valve sleeve is provided with two shaft seats (7), a shaft-depositing groove (8) and a shaft pressing plate fixing hole (12) are arranged on the shaft seat, a spring fixing ring (5) is arranged between the two shaft seats and is connected with the spring, and an included angle between the plane of the exhaust outlet and the plane of an exhaust inlet (17) is within 2 to 10 DEG. The soft cover valve is used for preventing the smoke flue from returning smoke to the kitchens.
Description
Technical field:
The utility model relates to a kind of flue that prevents and fall the device of cigarette in the kitchen, is specifically related to a kind of kitchen anti-backflow smoke soft cap valve.
Background technique:
The resident of inhabitation building generally is outwards to discharge fume by a common gas flue in the kitchen of how tame resident family under the upstairs house.The kitchen is not installed prevents the resident family of the device of falling the cigarette, the situation of return of smoke and smell in the kitchen often takes place.This had both caused unhappy to the people, also be harmful to health.At present, in order to prevent to fall cigarette in the kitchen, the most employing installed two semilune plate washers on smoke ventilator.This device bad sealing is close, still has the return of smoke and smell situation and takes place.The kitchen that prevents of other types is fallen the device of cigarette and is also all existed the tight inadequately shortcoming of sealing.And the applicant's the many ins and outs of 01228394.0 patent do not disclose, and are not easy to implement, and the soft lid of valve is provided with counterweight, has increased the smoke evacuation resistance.
Summary of the invention:
The purpose of this utility model provides a kind of kitchen anti-backflow smoke soft cap valve, can prevent that flue from falling cigarette in the kitchen, and is simple in structure, easy for installation.
Above-mentioned purpose realizes by following technological scheme:
The kitchen anti-backflow smoke soft cap valve, its composition comprises: the soft lid of valve sleeve and valve, wind exhausting outlet in the corresponding valve sleeve of the soft cover frame frame of described valve, described soft cover frame frame longitudinal plane is ㄣ shape, the waterproof cloth that is adhesively fixed on the described soft cover frame frame, described soft cover frame frame one side connects spring bearer plate, and there is circular shaft described spring bearer plate both sides, the spring fixed bolt is arranged, described spring fixed bolt fixing spring on the described spring bearer plate; Described valve sleeve has two axle beds, has the axial trough of putting and shaft pressuring plate fixed hole on the described axle bed, has the spring retaining ring between described two axle beds and connects spring, the angle that wind exhausting outlet plane in the described valve sleeve and air draft plane of inlet have the 2-10 degree.
The beneficial effects of the utility model:
The utility model since soft cover frame frame internal diameter greater than valve wind exhausting outlet external diameter, therefore during valve closing, under the spring force effect, the waterproof cloth in the soft lid can tightly contact with the valve wind exhausting outlet, cigarette can not take place down, can not return flavor.There is constant slope on valve wind exhausting outlet plane, blows down the easier soft lid of valve that blows open at smoke ventilator.The fixing soft cover frame frame of waterproof cloth, its longitudinal plane is ㄣ shape, has improved the rigidity of soft cover frame frame, long-term use not yielding yet.Anti-down smoke performance is reliable, and is simple in structure, and cost is low, easy for installation.

Embodiment:
Embodiment 1:
The kitchen anti-backflow smoke soft cap valve, its composition comprises: the soft lid of valve sleeve and valve, wind exhausting outlet 18 in the corresponding valve sleeve of the soft cover frame frame of described valve, described soft cover frame frame longitudinal plane is the ㄣ font in the Chinese Pinyin, the waterproof cloth 1 that is adhesively fixed on the described soft cover frame frame, described soft cover frame frame one side connects spring bearer plate 9, and there is circular shaft 6 described spring bearer plate both sides, spring fixed bolt 10 is arranged, described spring fixed bolt fixing spring 4 on the described spring bearer plate; Described valve sleeve has two axle beds 7, have axial trough of putting 8 and shaft pressuring plate fixed hole 12 on the described axle bed, have spring retaining ring 5 between described two axle beds and connect springs, there is the angle of 2-10 degree on wind exhausting outlet plane in the described valve sleeve and air draft 17 planes that enter the mouth.
The internal diameter of described soft cover frame frame greater than valve wind exhausting outlet external diameter 1mm about, about the wide 2mm in plane in the ㄣ shape structure; Soft cover frame frame hollow space is adhesively fixed on the plane in soft cover frame frame ㄣ shape structure with waterproof cloth (fiber weaving cloth one side compound one deck rubber membrane).
Described valve sleeve, soft cover frame frame and shaft pressuring plate all adopt the hard plastic injection molding moulding.Waterproof cloth 1 is adhesively fixed on the plane 3 of soft cover frame frame " ㄣ " shape structure 2.Spring 4 is placed in the spring retaining ring 5.Two circular shafts 6 of soft cover frame frame are placed on the putting in the axial trough 8 of two axle beds 7 in the valve sleeve respectively.This moment, spring bearer plate 9 just in time was pressed on the spring, and spring fixed bolt 10 is fixed spring.Shaft pressuring plate 11 is placed on respectively on two axle beds, the closure of openings of putting the axial trough top.Screw is screwed in the shaft pressuring plate fixed hole 12, and shaft pressuring plate promptly is fixed on the axle bed.Kitchen anti-backflow smoke soft cap valve assembling is finished.
Valve fixed plate 13, on the plane 15 of valve export end 14 1 sides, inject a circle silicon sealant.The valve export end is inserted the kitchen flue entrance compress, can be fixed on valve on the kitchen flue entrance wall on every side.Also make between valve and the flue entrance to be sealed, after smoke ventilator installs, the smoke ventilator outer pipe is enclosed within on the valve inlet end 16, fixing getting final product.
When the opened smoke-discharging machine, oil smoke blows soft lid open by valve air draft inlet 17, oil smoke enters in the flue, after closing smoke ventilator, under the spring force effect, valve closing, because soft cover frame frame internal diameter is greater than valve wind exhausting outlet 18 external diameters, the waterproof cloth at soft lid center can sternly contact with the valve wind exhausting outlet.Oil smoke and smoke in the flue all can not turn back in the kitchen.
