Background technique
At present; the flue gas that most of family produces when all adopting range hood to get rid of the cooking; flue gas is caused to emerge from smoke tube mouth; but the backflow of flue travel fatigue can have a strong impact on the environmental hygiene in kitchen; the sealing effect difference of the cooking-fume exhauster that market is bought thoroughly can not block oil smoke becomes the problem perplexing many families; people often can be subject to next door oil smoke " attack ", affect the normal quality of life of people.
Model utility content
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of ball valve preventing oil smoke counteroffensive in flue.
The technological scheme that the utility model adopts is: a kind of ball valve preventing oil smoke counteroffensive in flue, and this ball valve is made up of two housings and a spheroid, spheroid be positioned at two housings docking formed spherical cavity and with spherical cavity inwall close contact; Spheroid is provided with the knob of rotating sphere, and this knob is positioned at outside housing, and each housing and spheroid all have a through hole, and rotating sphere three through hole docks ball valve when being linked to be a passage to be opened, and the two ends of spheroid through hole are all closed with ball valve during body contact.
Further, each housing is circumferentially equipped with faying surface, affixed by fixed block after the faying surface docking of two housings.
Further, the two ends of each housing all have semicircular positioning hole, this positioning hole is provided with the semicircle spheroid confined planes consistent with its shape, the semicircle spheroid confined planes docking of two housings forms the circular locating openings limiting spheroid and rotate arbitrarily, the shape at spheroid two end part is cylindrical body, two cylindrical bodys lay respectively in corresponding circular locating openings, and each cylindrical exterior edge face is provided with knob.
Further, a housing in two housings is upper shell, and another housing is lower shell body, and upper shell through hole is opened in upper shell top, lower shell body through hole opens position corresponding with upper shell through hole bottom lower shell body, spheroid through hole is through the upper end of spheroid to lower end, and the aperture of three through holes is identical.
Further, upper shell through hole connects with flue, and lower shell body through hole connects with the outlet of range hood.
The beneficial effects of the utility model are: the utility model is contained between range hood and the pipeline leading to flue.When range hood works, valve open, the oil smoke in kitchen is discharged in building flue through range hood; When range hood does not work, valve closing, the oil smoke of main chimney flue is blocked in outside kitchen by ball valve, plays oil smoke blocking effect, reduces the effect of the oil smoke in kitchen, the outer surface of spheroid and spherical cavity inwall close contact, sealed by sphere-contact, improve sealing effect, play the effect thoroughly blocking oil smoke, also prevent oil smoke simultaneously and enter spherical cavity, in spherical cavity, stop deposition form dirt.Each housing is circumferentially equipped with faying surface, affixed by fixed block after faying surface docking, good airproof performance, and is easy to detachable maintaining and installation.The cylndrical surface at spheroid two ends is arranged in the corresponding positioning hole of two housings docking formation respectively, plays the effect that restriction spheroid rotates arbitrarily.The through hole of housing is positioned at the positive middle part in shell face, and spheroid through hole is through the upper and lower end of spheroid, and the aperture of three through holes is identical, can rotate knob by several angle, makes three through holes be easy to docking or block, easy to operate, time saving and energy saving.Hull shape is conducive to low cost molding and forming batch micro operations, and the same shape of two housings, can exchange, be conducive to industrial production.

Embodiment
As shown in Figure 1, 2, the utility model provides a kind of ball valve preventing oil smoke counteroffensive in flue.Ball valve comprises identical two housings, each housing is hemisphere, described two housings is circumferentially equipped with faying surface 2, it is affixed by fixed block after the faying surface 2 of two housings docks, faying surface 2 is flange plate, fixed block is bolt, two housings affixed formation one spherical cavity, be provided with in spherical cavity suitable with inner chamber size and with the spheroid 4 of spherical cavity inwall close contact; The two ends of each housing all have the positioning hole of semicircle type, and this positioning hole is provided with the semicircle spheroid confined planes 5 consistent with its shape.After two housings docking, the semicircle spheroid confined planes 5 of two housings docks and forms circular locating openings, and as shown in Figure 3, the shape at spheroid two end part is cylindrical body 8, two cylindrical bodys respectively correspondence are arranged in corresponding circular locating openings, and the exterior edge face of cylindrical body 8 is provided with the knob 7 of rotating sphere.A housing in two housings is upper shell 1, another housing is lower shell body 3, upper shell 1 top has position corresponding with upper shell through hole 6 bottom upper shell through hole 6, lower shell body and has lower shell body through hole 12, and the aperture that upper end to the lower end of spheroid 4 has spheroid through hole 9, three through hole is identical.Upper shell through hole 6 on upper shell connects with flue 13, and the lower shell body through hole 12 on lower shell body connects with the outlet of range hood 11.
During installation, the upper shell through hole 6 on upper shell 1 is connected by pipeline and flue 13, and the lower shell body through hole 12 on lower shell body 3 is connected with range hood 11, is fixed together between upper and lower casing by flange plate.In cavity in the middle of upper and lower casing, spheroid 4 is installed.The positioning hole that between upper and lower casing, restricted spheroid rotates arbitrarily, spheroid two terminal circle cylinder 8 coordinates with it.By the knob 7 on rotating cylinder 8 exterior edge face, spheroid 4 is rotated and change its position in spherical cavity, determine that ball valve is in "ON" or "off" state.As shown in Figure 4,5, before range hood 11 works, rotating sphere knob 7, spheroid through hole 9 is docked with upper shell through hole 6, lower shell body through hole 12, and ball valve is in open mode, makes oil smoke 10 can pass in and out this passage; As shown in Figure 6,7, when range hood 11 does not work, rotating sphere knob 90 degree, at this moment spheroid through hole 9 separates with upper shell through hole 6, lower shell body through hole 12, two ends and the housing close contact ball valve of spheroid through hole 9 are in closed condition, oil smoke 10 be blocked in outer not by, avoid entering kitchen.
