Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of laser bonding integrated ball valve.
Background technique
As everyone knows, ball valve is a kind of more conventional valve, and ball valve is mainly used as to cut off on pipeline, throttling, distribution and change media flow direction, has switch advantage fast.Ball valve generally comprises housing, valve rod, valve seat and flap, described flap is made as spheroid, described valve rod and flap are in transmission connection, described housing comprises valve body, valve body arm and valve rod sleeve pipe, described valve rod is axially fixedly connected with, is radially flexibly connected with valve stem casing pipe, between described valve rod and valve rod sleeve pipe, is provided with Sealing.The valve body of the ball valve of prior art, valve body arm and valve rod sleeve pipe adopt common welding or are threaded, there is the shortcoming that join strength is inadequate, in addition, the ball valve of prior art is when switch, valve seat and flap rub, all easily there are wearing and tearing and ball valve lost efficacy in valve seat and flap, has short shortcoming of poor sealing performance and working life.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the laser bonding integrated ball valve of a kind of intensity and good seal performance, long service life is provided.
The utility model solves the problems of the technologies described above adopted technological scheme: laser bonding integrated ball valve, comprise housing, valve rod, valve seat and flap, described flap is made as spheroid, described valve rod and flap are in transmission connection, described housing comprises valve body, valve body arm and valve rod sleeve pipe, described valve rod is axially fixedly connected with, is radially flexibly connected with valve stem casing pipe, between described valve rod and valve rod sleeve pipe, be provided with Sealing, described valve body, valve body arm and valve rod sleeve pipe become an overall structure by laser bonding; Described valve seat is arranged in the valve seat orifice of valve body arm, and described valve seat is axially flexibly connected, is radially fixedly connected with the valve seat orifice of valve body arm; In the valve seat orifice of valve body arm, be also provided with elastic compensating device, the elastic force of described elastic compensating device closely cooperates valve seat all the time with flap.
Useful technique effect of the present utility model is: because valve body of the present utility model, valve body arm and valve rod sleeve pipe become an overall structure by laser bonding, by the purification of laser bonding and high rate of cooling, guaranteed compactness and the join strength of housing weld seam.Thereby have advantages of that intensity, toughness and combination property are high.In addition, the utility model is provided with elastic compensating device in the valve seat orifice of valve body arm, the elastic force of elastic compensating device closely cooperates valve seat all the time with flap, when there are wearing and tearing between valve seat and flap, there is the compensating action of eliminating seal clearance, thereby also there is good seal performance, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
