Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of one and enters three and go out formula four-way reversing globe valve.
Background technique
Ball valve is mainly used in cutting off or connecting pipeline medium, and because it is simple to operate, the features such as flow resistance is little, are used widely in every field in recent years.The four-way reversing globe valve used when changing medium runner by ball valve is at present " LL " type selector valve, and namely by every rotary ball valve spool 90 °, to switching once, realize runner two enter scene 2 to MEDIA FLOW.But need an import in reality, when three directions are respectively as outlet, this valve is not enough to meet performance, if use multiple stop valve as cutting off the valve flow to, causes the wasting of resources, and complex interfaces.
Summary of the invention
The purpose of this utility model is that a kind of commutation function is many in order to provide, structure is simple and one enters three and goes out formula four-way reversing globe valve.
The purpose of this utility model is achieved in that and comprises valve body, be arranged on the valve gap of valve body upper end, be arranged on the valve rod of valve inner and be arranged on the ball valve core of valve rod lower end, in the part that described valve rod passes valve gap, fixed cover is equipped with handwheel, and set screw nut is installed on the top of valve rod, described valve body evenly arranges four female mounting holes of tool along outer surface circumference, four valve ports are arranged in described mounting hole by outside thread, the neutral position of ball valve core has medium channel, described medium channel is made up of vertical holes and circular groove, the diameter of described vertical holes and the equal diameters of valve port, the thickness of described circular groove equals the diameter of valve port, the arc angle of described circular groove is 90 °, and the plane at described medium channel place is vertical with valve rod.
The utility model also comprises some structure characteristics like this:
1. at valve body and valve gap contacting point, valve gap and valve stem contacts place, valve body and valve port contacting point, seal ring is set respectively.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts the spool of special construction principle, by rotating the commutation of handwheel band movable valve plug thus realizing the conducting and cut-off that ball valve import exports with three respectively, be applicable in the pipeline of road import three way outlet, namely only an import is needed, every rotational valve core 45 ° can realize and the conducting of its excess-three direction pipeline or cut-off, and in pipeline connects, the utility model structure is simple, commutation function is more, be convenient to I&M, the function of valve generation four valves can be realized, simultaneously in a pipeline runner entering to have more, pipeline can be made to connect simple, multi-purpose valve, save cost.
