Embodiment Construction

[0024] Such as Figures 1 to 5 As shown, in the preferred embodiment of the cam compression type three-way ball valve of the present invention, it includes a valve body 10, a spherical valve core 20, a rotation driving mechanism, and a compression mechanism. Among them, the valve body 10 is provided with an inlet 11 and two outlets 12a, 12b, between the inlet 11 and the outlets 12a, 12b is a hollow valve cavity 13, and the valve cavity 13 is set in a spherical shape matching the valve core 20. A communication passage 23 is provided in the valve core 20, and the communication passage 23 can communicate the inlet 11 with an outlet 12a or 12b. The rotation drive mechanism includes a drive shaft 31 and a power source (not shown in the figure), and the power source may be a power device such as a motor that can make the drive shaft 31 rotate as required. The drive shaft 31 is rotatably arranged on the valve body 10, one end of which is connected to the valve core 20, and the other...

Abstract

The invention relates to a cam pressing type tee ball valve, comprising a tee valve, a valve plug and a rotation driving mechanism for driving valve plug to rotate disposed in the tee valve, and a pressing mechanism disposed on the valve. The pressing mechanism comprises a pressing shaft driven by external and a pressing cam which is fixed on a stretching end of a pressing shaft inserted into the valve. A cam counter bore which is matched with the pressing cam is disposed on the valve plug. During the rotation of valve plug, the valve plug always inclines towards one side of an inlet of the valve and the sealing surfaces of the valve plug and an outlet do not contact with each other so the sliding friction problem of prior art does not exist and the service life of the valve is prolonged.

Description

technical field [0001] The present invention relates to a three-way ball valve, more specifically, to a cam pressing type three-way ball valve. Background technique [0002] A general ball valve includes a valve body and a spherical valve core arranged in the valve body. The valve core is provided with a communication channel connecting the inlet to the outlet, and the valve body is provided with a rotating drive mechanism that drives the valve core to rotate in the valve body. The valve core can be driven to rotate through the rotating drive mechanism, so that the channel is aligned with or deviates from the inlet and outlet, so as to realize the opening or closing of the valve. The internal sealing between the valve body and the valve core is mainly through the arrangement of elastic elements such as gaskets on the wall of the valve cavity in the valve body, and the gaskets are used to cooperate with the valve core. When opening and closing the ball valve, there is slidin...
