Embodiment Construction
[0024] Below in conjunction with accompanying drawing and embodiment of description, specific embodiment of the present invention is described in further detail:
[0025] refer to Figure 1 to Figure 8 The shown dual-purpose three-way valve includes a three-way valve body 1 and a valve core 2, and the three-way valve body 1 is provided with a main connecting pipe 1a, two sub-connecting pipes 1b and a control pipe 1c; The two sub-connecting pipes 1b are coaxial and perpendicular to the main connecting pipe 1a; the control pipe 1c is coaxial with the main connecting pipe 1a; the valve core 2 is a cylindrical structure and is rotatably inserted into the Located in the control pipe 1c, the front end of the valve core 2 extends to the junction of the main connecting pipe 1a and the sub-connecting pipe 1b; the front end of the valve core 2 is provided with an elliptical surface 3 with an inclination angle of 45 degrees.
[0026] The cylindrical surface of the spool 2 is provided wi...

The invention relates to the technical field of valve bodies, in particular to a dual-purpose three-way valve. The dual-purpose three-way valve comprises a three-way valve body and a valve element. The three-way valve body is provided with a main connecting pipe, two branch connecting pipes and a control pipe. The two branch connecting pipes share the same axis and are perpendicular to the main connecting pipe. The control pipe shares the same axis with the main connecting pipe. The valve element is of a cylindrical structure and can be rotatably inserted in the control pipe. The front end of the valve element extends to the connecting position of the main connecting pipe and the branch connecting pipes. An elliptical face with the inclination angle of 45 degrees is arranged at the front end of the valve element. According to the dual-purpose three-way valve, the main pipe can be communicated and disconnected with the two branch pipes at the same time, and in addition, the requirement that the main pipe is communicated with any branch pipe can be met. The dual-purpose three-way valve has the functions of common tee joints and traditional three-way valves and is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to the technical field of valve bodies, in particular to a dual-purpose three-way valve. Background technique [0002] Three-way valves, especially three-way valves, are widely used in various pipeline systems. The traditional three-way valve body has three ports, one in and two out. Different from ordinary valves, there is an outlet at the bottom of the three-way valve. When the internal spool is in different positions, the outlets are different. For example, when the spool is at the bottom, the left and right are connected. It is connected with the lower mouth (or the left side outlet is blocked, and the right side is connected with the lower mouth). [0003] It can be seen that the three-way valve can realize the simultaneous connection of the main pipeline and the two branch pipelines, and the three-way valve can realize the simultaneous disconnection of the two branch pipelines or the connection of any branch pipeline with t...
