Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, this embodiment provides a three-way ball valve, which includes a valve body 1, a ball 2, a fixing member 3, an upper valve stem 4, a lower valve stem 5, a coupling 6, and a driving device (not shown in the figure) And the lower valve cover 7, the support plate 15 is located on the upper side of the valve body 1, and the lower valve cover 7 covers the lower opening of the valve body 1. It should be noted, figure 1 and figure 2 The left side is the main view, and the right side is the section view.

[0028] Such as image 3 As shown, the interior of the valve body 1 is hollow to form a cavity channel 101 , and a mounting hole 103 and three first openings 102 are provided on the side wall of the valve body 1 , and both the mounting hole 103 and the first openings 102 communicate with the cavity channel 101 .

[0029] In this embodiment, the inner hollow ball 2 is arranged in the cavity channel 101 of the three-way ball valve....

Embodiment 2

[0038] This embodiment provides another three-way ball valve, which is basically the same as Embodiment 1, and only the different parts will be introduced below.

[0039] Such as figure 1 As shown, in this embodiment, the three-way ball valve also includes an upper bonnet 9, the upper bonnet 9 is located on the upper side of the support plate 15, and is fixed to the upper side of the valve body 1 through the support plate 15, and the upper valve stem 4 passes through Over the upper valve cover 9, and connected with the upper valve cover 9 in rotation. The upper valve cover 9 can better protect the valve body 1 .

[0040] Preferably, as figure 2 As shown, the three-way ball valve also includes a shaft sleeve 10 and a thrust pad 11, through which the upper valve stem 4 is rotationally connected with the upper valve cover 9, the inner side of the shaft sleeve 10 fits the upper valve stem 4, and the thrust pad 11 is placed on Above the shaft shoulder of the upper valve stem 4 ...

Embodiment 3

[0043] This embodiment provides another three-way ball valve, which is basically the same as Embodiment 1, and only the different parts will be introduced below.

[0044] Such as figure 1 and Figure 5 As shown, in this embodiment, the three-way ball valve also includes two connectors 13, and the two connectors 13 are respectively fixed on the upper surface 202 and the lower surface 203 of the ball 2, and the upper valve stem 4 passes through the upper surface of the ball 2. The connector 13 is keyed to the sphere 2 , and the lower valve stem 5 is rotatably connected to the sphere through the connector 13 located on the lower surface of the sphere 2 . Wherein, the upper valve stem 4 is keyed to the sphere 2 through the connector 13, and the lower valve stem 5 is rotatably connected to the sphere 2 through the connector 13, which simplifies the connection structure between the upper valve stem 4 and the lower valve stem 5 and the sphere 2.

[0045] Preferably, the three-way b...

Abstract

The invention discloses a three-way ball valve. The three-way ball valve comprises a valve body, a ball body, a fixing piece, an upper valve rod, a lower valve rod, a supporting disc, a coupling and adriving device; the interior of the valve body is provided with a hollow cavity channel; the side wall of the valve body is provided with an installation hole and three first openings; the side wallof the ball body is detachably connected with the fixing piece, the fixing piece is rotated through the installation hole, and accordingly, the ball body in the cavity channel can be rotated; the upper valve rod and the ball body are connected through a key, one end of the upper valve rod is fixed to the center of the upper surface of the ball body, and the other end of the upper valve rod penetrates through the valve body to be connected with the supporting disc and the coupling; and the coupling is connected with the driving device. The three-way ball valve provided by the invention is simple in structure, the size and weight of the three-way ball valve are effectively decreased, and in addition, the installation difficulty and the installation cost of the three-way ball valve are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a three-way ball valve. Background technique [0002] As a pipeline valve, the three-way ball valve is mainly suitable for the application conditions of switching, reversing, and diversion of gas or liquid media. The gas or liquid medium generally flows in from one side of the axial port of the ball valve, and flows out from the other axial port and / or the axial vertical side port, and the direction of outflow can be between the other axial port and the axial vertical side port. to switch between. [0003] At present, for large-diameter three-way ball valves with pipe diameters above DN300, since the outer diameter of the ball in the three-way ball valve is proportional to the diameter of the medium channel, and the larger the diameter of the three-way ball valve, the diameter of the medium channel of the three-way ball valve The bigger the ball is, the outer diameter of the bal...
