Description

Symmetrical three-way ball valve

Technical field

The invention relates to a three-way valve, in particular to a symmetrical three-way ball valve with jet function.

Background technique

The existing closed circulation pipeline system, whether it is a water pipe, a gas pipe or a hot water heating pipe, has always used the common three-way pipe fittings of the same structure, as shown in the building materials manual. But in practice, due to the different pressures (pipe pressure or resistance) of the media in different pipes, when the media in different pipes meet, there will be a pressure loss in the pipe, that is, "pipe loss", so that the energy cancels each other out, and the pipe with the highest pressure The pipe obstructs the normal flow of other pipe branches, reducing the efficiency of the pipe system for conveying media.

Contents of the invention

In order to solve the above-mentioned "pipe loss" problem, according to the principle of jet technology, the pressure energy of each pipeline is fully utilized, so that the pressure of each pipeline does not offset but introduces and promotes each other, that is, the introduction of the medium in the pipeline with the highest pressure pushes the medium in the pipeline with other medium pressure , so that the mixed medium can be smoothly transported to the direction of the pipeline with the least pressure.

The scheme adopted by the present invention to solve its problem is:

The axes of the three pipelines on the body of the symmetrical three-way ball valve form an angle of 120 degrees in pairs. The symmetrical three-way ball valve is composed of a valve body, a valve core, a connecting rod and a handle, all of which can be processed by the existing technology. The handle can be continuously rotated counterclockwise or clockwise or rotated back and forth; The axis of the pipeline is two by two into a 120-degree angle; the spool is fixedly connected with the connecting rod, and there are two through-holes in the spool that are at an angle of 120 degrees and pass through the center point of the spool, and the ports of these three through-holes ( spool port) can correspond to any of the three lines on the valve body. Just by rotating the handle to drive the valve core to rotate an angle, the three pipelines can be fully opened, so that the mixed medium can quickly and easily flow to the pipeline with the lowest pressure. The three pipelines can also be fully closed at the same time, and the switching between opening and closing is rapid and efficient.

The beneficial effects of the present invention are: the medium in the pipeline with the highest pressure can be introduced to push the medium in the pipeline with medium pressure, so that the mixed medium can quickly and easily flow to a pipeline with the lowest pressure, and the flow rate is large and the pipe loss is small; the handle can be Counterclockwise or clockwise drives the spool to rotate continuously or back and forth, and the three pipelines can be fully opened or fully closed at the same time.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be further described below in conjunction with the schematic structural diagram of the present invention.

Figure 1 is the B-B sectional view of Figure 2

Figure 2 is the A-A sectional view when the ball valve in Figure 1 is in the open state

Figure 3 is a cross-sectional view of the ball valve in Figure 2 when it is in a closed state

In the figure, a connecting rod 1, a handle 2, a valve body 3, a valve core 4, a valve core port 5, a valve core port 6, a valve core port 7, a pipeline 8, a pipeline 9, and a pipeline 10.

Detailed ways

The handle 2 is fixedly connected with the upper end of the connecting rod 1, and the lower end of the connecting rod 1 is inserted into the valve body 3 and fixedly connected with the spherical valve core 4 placed in the valve body. When the handle is turned so that the port of the valve core is opposite to the pipeline, the three ports of the valve core can correspond to any one of the three pipelines on the valve body, and the three pipelines can be connected (as shown in Figure 2). The symmetrical three-way ball valve is in the Open state; when the handle is turned to stagger the spool port and the pipeline (as shown in Figure 3), the symmetrical three-way ball valve is in the closed state. It can be quickly switched between on and off, and the handle can drive the valve core to rotate continuously or back and forth counterclockwise or clockwise.

For example, when the symmetrical three-way ball valve is applied to the water tank of the toilet, the pipeline 8 can be directly connected to the tap water pipe, the pipeline 9 can be connected to the water outlet of the existing water tank, and the pipeline 10 can be directly connected to the water intake of the toilet. When in use, the symmetrical three-way ball valve is in the open state. At this time, two streams of water from the pipeline 8 and the pipeline 9 will be injected into the pipeline 10 at the same time. , The flushing water flow is urgent and the time is short. Also, the symmetrical three-way ball valve can be closed quickly, so that the water retention in the toilet is small, and water is saved.
