Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of ball check valve that has check function.
Background technique
As everyone knows, ball valve is a kind of common valve, does cut-out on the pipeline of fed sheet of a media, distribute and change the media flow direction used.On industry such as combustion gas, hot-water heating and civilian pipeline, ball valve has obtained extensive use because of it is simple in structure, easy to operate, but ordinary ball valve has only and connect and the function of damming, and all two-way circulates under normal conditions, does not have the medium of prevention refluence effect.When equipment such as measuring instrument, water pump are installed on the pipeline, when requiring medium not flow backwards or to want the emptying medium, safety check to be installed also on pipeline usually, safety check has the effect of unidirectional current limliting, has worked the medium refluence effect that prevents in pipeline.In order to reach the double action of control media circulation and unidirectional current limliting, often mounting ball valve and safety check simultaneously in pipeline, like this, make the pipeline structure complexity, cost improves, and it is big to take up space, and the increase pipe interface, increase leakage point, be unfavorable for pipeline safety.
The model utility content
Problem to be solved in the utility model provides a kind of can the circulation, cut off, distribute by control media, can prevent that again medium from flowing backwards, realizing the non-return structure ball valve of unidirectional current limliting.
For addressing the above problem, the utility model by the following technical solutions:
A kind of ball check valve comprises valve body, has valve pocket in the valve body, is provided with ball-cock device in the valve pocket, and described valve body is provided with sealed mouth near a side of ball-cock device water outlet, and the position near sealed mouth in the valve pocket is equipped with check device.
Below be the utility model for further improvement of these options:
Described check device comprises the guide sleeve that is connected with valve body, is provided with check cavity in the described guide sleeve, is provided with slide block in the check cavity, and slide block is connected with rubber cushion near an end of sealed mouth.
Further improve: the end of guide sleeve is provided with end plate, is provided with osculum on end plate.
Further improve: the inwall upper edge axial direction of described guide sleeve is provided with some fins, forms water-flowing trough between the adjacent fin.
Further improve: the position in the described check cavity between slide block and end plate is provided with several boss.
Further improve: be tightly connected by rubber sheet gasket between an end of the close sealed mouth of described guide sleeve and the valve body.
The another kind of improvement:
Described ball-cock device comprises the valve seat that is arranged on the valve body, and valve rod is installed in valve seat, and the lower end of valve rod is connected with valve ball, described valve ball in valve pocket and and valve pocket between sealed sliding be dynamically connected, valve ball is provided with the water port.
During use, move handle, by valve rod valve ball is rotated, when the water port on the valve ball is communicated with water intake, liquid enters sealed mouth from water intake, and push in the check cavity slide block to a side near end plate, liquid enters in the check cavity and through the space between water-flowing trough and the boss and enters osculum then, flow out by water outlet at last, when valve ball was closed or run in the system liquid and flow backwards, liquid entered into check cavity from water outlet and osculum, owing to be provided with slide block in the check cavity, liquid forms certain pressure to slide block, impel slide block to drive rubber cushion and move to the end near sealed mouth, when moving to the right side of check cavity, rubber cushion seals sealed mouth, prevent the liquid refluence, realized unidirectional current limliting.
The utility model is organically combined safety check and ball valve, one valve is dual-purpose, has reduced the product cost, has effectively saved resource, the utility model has reduced installation difficulty, reduced the probability that problems such as dropout, seepage appear in the joint, non-return wherein partly adopts rubber gasket to match with sealed mouth on the valve body, has realized the wire sealing, compare with the safety check of routine, have good sealing effect, long service life is difficult for the advantage that there was a mechanical failure.
The utility model is described in further detail below in conjunction with drawings and Examples:
