Description
Technical field
The invention belongs to control valve for fluids technical field, relate to a kind of tee ball valve with import cutting function and outlet isolation features, isolation ball valve is cut off in specifically a kind of three pieces type L-type threeway.
Background technique
Tee ball valve is generally divided into T-shaped and L-type.T-shapedly three orthogonal pipelines can be made to be interconnected and to cut off Article 3 pipeline, play shunting, interflow effect; L-type can only connect two mutually orthogonal pipelines, plays distributional effects.In valve function transfer process, the import of valve can keep being communicated with without pressure reduction with outlet each other.
The tee ball valve of these routines cannot meet the needs of modernization industry.On some vacuum system devices of such as chemical industry, three one, pipelines are medium entrance pipeline, have one for vacuum pipe in two outlets.Whenever often can require under these operating modes that tee ball valve not only has import cutting function, and require to have outlet isolation features, namely two outlet conduits do not allow the situation that occurs being interconnected in any case.Obviously, conventional L-type or T-shaped tee ball valve cannot meet this generic request.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide the threeway of a kind of structure simple, ingenious, rational three pieces type L-type to cut off isolation ball valve, this ball valve effectively can realize the function cut off and isolate.
According to technological scheme provided by the invention: isolation ball valve is cut off in a kind of three pieces type L-type threeway, it is characterized in that: comprise middle valve body, described middle valve body is left, right two ends attachment face is fixed respectively a side valve body, the gyration center of each side valve body is all through is provided with outlet passage, the gyration center of middle valve body is through is provided with inlet passage, valve ball with valve rod rotates and is arranged on middle valve body, the inner diameter of axle of each described side valve body is provided with spring and valve component, valve component forms sealing by spring compression on valve ball, upper cover to be sheathed on valve rod and to be fastened by bolts on middle valve body, described valve ball is provided with runner hole, the lower end import of runner hole is connected with inlet passage, and valve ball realizes the outlet in runner hole and being communicated with or closedown of outlet passage in rotation process.
As a further improvement on the present invention, described valve component comprises valve seat, filler, trim ring.
As a further improvement on the present invention, pad is respectively arranged with between described middle valve body and side valve body and between upper cover and middle valve body.
As a further improvement on the present invention, seal ring is provided with between the entrance point in described runner hole and inlet passage upper stage terrace.
As a further improvement on the present invention, described runner hole is L-type.
Compared with prior art, advantage is in the present invention: product of the present invention can realize import cutting function.Select 0 ° of-90 °-180 ° 3 stops actuator, initial position and end position realize being communicated with of import and outlet, and neutral position realizes the cut-out of valve; Can realize exporting isolation features.In valve function transfer process, two outlets remain isolation, there will not be the situation exporting and be interconnected; Good rigidly, opens and closes moment little.Valve ball and valve rod are integrated type forging, and good rigidly, amount of deformation is little.Fixing spherical structure, valve torque is little, and valve event is steadily reliable.
