Abstract
The utility model relates to a ball check valve. A valve clack is arranged between a ball body placed in the ball valve and a media outlet, has the direction consistent with a pipeline and can move along the pipeline. The head of the valve clack faces the ball body and has the cross section serve as an inclined surface corresponding to the inclined surface of the pipeline and the bottom larger than the diameter of the pipeline. Thanks to the arrangement of the valve clack, the utility model has a return stopping function and can prevent the return of the media; compared with the arrangement of the ball valve and the check valve, the utility model has the installation more convenient and reduces the cost.
Description
Technical field
The utility model relates to a kind of valving, is specifically related to a kind of ball check valve device with check function.
Background technique
Existing ball valve is a kind of common valve, and main cut-out, distribution and the change media flow direction done used on pipeline.The flap of existing safety check relies on the media flow automatic opening-closing, can stop the medium in the pipeline to flow backwards.Because existing ball valve does not have the effect that stops medium to flow backwards, therefore in being equipped with the pipeline of ball valve in order to prevent that medium from flowing backwards, also a safety check need be installed again, thus make install complicated, the cost height, increase takes up space.
The model utility content
In order to overcome the single deficiency of existing ball valve or check function, the utility model provides a kind of ball check valve, and this valving not only has the function of ball valve, and has the function that safety check can stop medium refluence in the pipeline simultaneously, thereby make easy for installationly, save cost.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of ball check valve comprises valve body, valve seat, valve rod, spheroid, handle and flap, and spheroid is installed in the valve body, and the lower end of valve rod is connected with the spheroid upper end, fixedlys connected with handle in the upper end of valve rod, and rotating handles makes the spheroid rotation, opens or throttle down; Flap is installed in the valve seat of valve body, and between spheroid and media outlet end, flap is consistent with the direction of pipeline, and can move along pipeline.
The head of described flap is towards spheroid, and its cross section is and corresponding inclined-plane, pipeline inclined-plane that its bottom surface is greater than the diameter of pipeline.
The utility model since in ball-cock device, be equipped with consistent with the pipeline direction, and the flap that can move along pipeline, and the bottom surface on flap inclined-plane is greater than pipe diameter, thus can block the approach that medium flows backwards.
The beneficial effects of the utility model are: make ball valve have check function, thereby make simple installation, save cost.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified
In the embodiment of the utility model ball check valve shown in Figure 1, comprise valve body 1, valve seat 14, valve rod 6, spheroid 4, handle 9 and flap 11.Spheroid 4 is installed in the valve body 1, and 1 of valve body is equipped with seal arrangement.The lower end of valve rod 6 is connected with spheroid 4 upper ends, fixedlys connected with handle 9 in the upper end of valve rod 6, and rotating handles 9 makes spheroid 4 rotations, opens or throttle down.Flap 11 is installed in the valve seat 14 of valve body, and between spheroid 4 and media outlet end, flap 11 is consistent with the direction of pipeline, and can move along pipeline, the head of this flap 11 is towards spheroid 4, and its cross section is and corresponding inclined-plane, pipeline inclined-plane, and its bottom surface is greater than pipe diameter.Seal ring 10 is housed between flap head and valve body.Movement direction for the control flap is equipped with a setting sleeve 13, and between setting sleeve 13 and flap head spring 12 is housed on valve petal body.
