Description
Technical field
The utility model relates to a kind of fluid control valve, particularly a kind of Blowoff ball valve.
Background technique
Ball valve is mainly used to flowing of liquid in the pilot line and closes in pipeline, and some physical parameters of monitoring fluid, and it only need to just can be closed tightly with the operation of 90-degree rotation and very little moment of rotation.Generally do switch or cut-off valve and use, be characterized in that fluid resistance is little, switch is convenient, is widely used in the industrial fields such as civil area and central air-conditioner, HVAC, oil, chemical industry.
Known ball valve is mainly by valve body, valve gap, ball valve core, valve rod and handle with sleeve form, described valve body vertically part is provided with the runner that connects medium, described runner has water intake and water outlet, valve gap is located at valve inleting water mouth one side, described ball valve core is rotatable to be installed in the valve body, between the water outlet, this ball valve core is provided with and advances, the fluid latus rectum that water outlet is connected, one end of described valve rod passes the valve body upper side wall and links to each other with ball valve core, described handle with sleeve is located on the free end of valve rod and is worked to open ball valve core or close ball valve core, above-mentioned ball valve only has often to be opened or normally closed function, can not directly get rid of the dirt that the valve body inner product is pressed, used of a specified duration and can be deposited in advancing of valve body, in water outlet or the ball valve core, pipeline blockage or rate of flow of fluid are descended, affect the normal conveying of medium.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of rational in infrastructurely, cost is low, pipeline is difficult for stopping up, rate of flow of fluid is stable, can directly get rid of the Blowoff ball valve of dirt in the valve body.
For solving this technical problem, the utility model is taked following scheme: a kind of Blowoff ball valve, comprise valve body, ball valve core, valve rod, opening device, described valve body is provided with water intake and water outlet vertically, described ball valve core is located between the interior water intake of valve body and the water outlet, this ball valve core is provided with and advances, the fluid latus rectum that water outlet is connected, one end of described valve rod passes the valve body upper side wall and links to each other with ball valve core, described opening device is located on the free end of valve rod, described valve body is positioned on the valve wall of water intake or water outlet and has the blowdown through hole, the removable seal plug that is provided with in the described blowdown through hole.
Further improvedly be: be provided with seal ring between described seal plug and the blowdown through hole.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the utility model Blowoff ball valve, described valve body is positioned on the valve wall of water intake or water outlet and has the blowdown through hole, the removable seal plug that is provided with in the described blowdown through hole, can directly get rid of the dirt that the valve body inner product is pressed by the blowdown through hole, when needing blowdown, the interior seal plug of blowdown through hole of only need outwarding winding can carry out blowdown to the dirt that accumulates in the valve body, it is rational in infrastructure, cost is low, blowdown is convenient, dirt can not occur accumulating in the valve body and cause phenomenon pipeline blockage or that rate of flow of fluid descends, can guarantee the normal conveying of medium.
Description of drawings
