Detailed Description
An all-welded three-way ball valve as shown in fig. 1 and 2 comprises a middle body 1, three connecting pipes 2, a three-way valve core 3, three valve seats 4 and a valve rod 5, wherein the middle body 1 is cylindrical, openings are respectively arranged at two ends and on the side wall of the middle body 1, the three connecting pipes 2 are respectively arranged at the corresponding three openings, the three connecting pipes 2 are arranged in a T shape, and the outer walls of the three connecting pipes 2 are respectively fixed with the openings in a welding mode, so that the all-welded three-way ball valve has the structural characteristics of an all-welded valve. The valve rod 5 penetrates through the middle body 1, the lower end of the valve rod 5 extends into the middle body 1 and is connected with the three-way valve core 3, the three valve seats 4 are respectively installed on the pipe orifices of the three connecting pipes 2 in the middle body 1, and the three valve seats 4 are respectively in sealing fit with the three-way valve core 3. The middle body 1 and the three connecting pipes 2 are welded into a whole, circular steel pipes with corresponding calibers and wall thicknesses can be selected to be manufactured, the steel pipes are cut into sections, corresponding necessary processing is carried out, and finally welding is carried out at seams.
The diameter of the openings at the two ends of the middle body 1 gradually increases towards the middle, and the whole middle body 1 is in a cylindrical shape with a large middle and two small sides.
The three-way valve core 3 is internally provided with an L-shaped channel 31 or a T-shaped channel. The L-shaped channel can only connect two mutually orthogonal pipelines, cannot simultaneously keep the mutual communication of the third pipeline, and only plays a role in distribution. The T-shaped channel can enable three orthogonal pipelines to be mutually communicated and cut off a third channel, and functions of shunting and converging are achieved.
