Problems solved by technology

[0004] Obviously, although the above-mentioned valve structure is relatively simple, its function is relatively single, that is to say, it can only pass hot water or cold water.
If it is necessary to mix hot water and cold water to achieve the required temperature of water, the above valve is difficult to achieve this purpose

Embodiment Construction

[0021] As shown in Figure 1, the three-way ball valve includes a valve body 1, a valve core 2, a valve stem 3 and a handle 4. The interior of the valve body 1 is a cavity, that is to say, the valve body 1 has two water inlet channels 1a and A water outlet channel 1b.

[0022] The two water inlet channels 1a form an L shape, and the inlet end of the water outlet channel 1b communicates with the corners of the L shape of the two water inlet channels 1a.

[0023] As shown in FIG. 1 and FIG. 2 , there are two valve cores 2 , valve stems 3 and handles 4 . One of the valve cores 2 is installed in one of the water inlet channels 1a, the inner end of the valve stem 3 is fixedly connected with the valve core 2, the outer end of the valve stem 3 passes through the valve body 1, and the handle 4 is fixedly connected with the valve stem 3 outer end. The other valve core 2 is installed in another water inlet channel 1a, and the valve stem 3 and the handle 4 are connected in the same way,...

Abstract

The invention provides a three-way ball valve, which belongs to the machinery technical field and solves the problem that the prior three-way ball valve is single in function, poor in applicability, etc. The three-way ball valve comprises a valve body, valve cores, a valve stem and a handle, wherein water inlet channels and a water outlet channel are arranged on the valve body; the valve cores are arranged inside the valve body between the water inlet channels and the water outlet channel; the inner end of the valve stem is connected with the valve cores; the outer end of the valve stem passes through the valve body and then is connected with the handle; the number of the water inlet channels is two, and inlets of the two water inlet channels are both communicated with the positions of the valve cores; two valve cores are respectively arranged inside the two water inlet channels; the valves cores are respectively connected with the valve stem and the handle. The three-way ball valve is characterized in simple structure and high applicability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a valve, in particular to a three-way ball valve. Background technique [0002] Valves are widely used in industry and daily life. It is a device used to make or stop the fluid medium in the pipeline system and control its flow. [0003] Existing valves usually consist of a two-way valve body, a valve core mounted in the valve body, a valve stem connected to the valve core, and a handle fixedly connected to the valve stem. When the valve needs to be operated, the handle can be pulled to drive the valve core to rotate through the valve stem. After the spool rotates, the purpose of controlling the fluid medium in the pipeline system can be achieved. [0004] Obviously, although the above-mentioned valve structure is relatively simple, its function is relatively single, that is to say, it can only pass through hot water or cold water. If it is necessary to mix hot water and cold w...
