Problems solved by technology

[0004] Therefore, it is very important to develop a three-way ball valve that can keep the flow area and flow rate of the water inlet channel of the valve body constant when the valve is adjusted, and can discharge the valve cavity and pipeline waste liquid in time. The prior art lacks similar functions. structure

Embodiment Construction

[0031] The present invention will be further described below with reference to the drawings and embodiments.

[0032] Such as figure 2 As shown, the present invention includes a left valve body 17, a right valve body 5, a valve core 11 and a sewage ball valve 15. The two ends of the left valve body 17 are open to form an inlet flow passage III, such as Picture 9 As shown, the right valve body 5 is provided with a connection port, a sealing end, a first outlet flow channel I and a second outlet flow channel II around the right valve body 5, a sewage flow channel IV is opened at the bottom of the right valve body 5, and one end of the left valve body 17 is fixedly connected to The connection port of the right valve body 5 makes the left valve body 17 and the right valve body 5 fixedly connected to form a valve body structure with a valve cavity, three flow passages communicating with the valve cavity and a sealed end, and the four flow passages converge at In the valve cavity, th...

Abstract

The invention discloses a T-shaped three-way ball valve with a sewage discharge function. The T-shaped three-way ball valve comprises a left valve body, a right valve body, a valve core and a sewage discharge ball valve. The two ends of the valve bodies are open to form an inlet runner. The periphery of the right valve body is provided with a connection end opening, a seal end, a first outlet runner and a second outlet runner. A sewage discharge runner is formed in the bottom of the right valve body. One end of the left valve body is fixedly connected to the connection end opening of the right valve body. The incomplete-spherical valve core is arranged in a valve cavity. A large valve rod used for driving the valve core to rotate is connected to the upper end of the valve core. The sewage discharge runner is located under the valve core and is internally provided with the sewage discharge ball valve. The lower end of the valve core is connected with the sewage discharge ball valve. The three-way ball valve can keep the flowing area of a valve body water inlet channel during flow adjustment and distribution and then can keep the flow of the water inlet channel unchanged, the three-way ball valve can be effectively protected when corrosive liquid is conveyed, corrosion of the corrosive liquid to the three-way ball valve is reduced, and the service life of the three-way ball valve is prolonged.

Description

Technical field [0001] The invention relates to a ball valve, in particular to a T-shaped three-way ball valve with drain. [0002] technical background [0003] The T-type three-way ball valve is used to split, merge and switch the flow direction of the medium in the pipeline. When a three-way ball valve is used for flow regulation and flow distribution, it is usually required that the flow of the inlet channel is not changed, and the flow of the two outlet channels is distributed by adjusting and changing the opening of the three-way ball valve. However, when the ordinary three-way ball valve adjusts the flow of the two outlet channels, the flow channel area of ​​the inlet channel of the three-way ball valve will also be greatly changed due to the obstruction of the ball. figure 1 As shown, therefore, the conventional three-way ball valve is not suitable for system flow adjustment and distribution. When the ball valve is closed, there will be residual liquid in the valve cavity ...
