Description

Technical Field

[0001] The utility model belongs to the technical field of three - way ball valves, and particularly relates to a drainage - type press - fit three - way ball valve. Background Technique

[0002] The press - fit three - way ball valve is a valve used in a pipeline system. It has three main flow channels and can achieve the diversion, confluence or flow - direction change of the medium. The working principle of this valve is to control the fluid flow by rotating the sphere inside the valve body. The sphere usually rotates 90 degrees around the center line of the valve body to open or close the valve.

[0003] The existing three - way ball valves are mainly used to achieve the diversion, confluence or flow - direction change of the medium in the pipeline system, but most of them do not have an effective drainage function. In some application scenarios, such as the chemical, pharmaceutical or food processing industries, the liquid accumulation in the pipeline needs to be drained regularly to prevent bacterial growth or equipment corrosion. At present, this process often requires disassembling the pipeline or using additional drainage equipment, which is cumbersome and inefficient. Content of the Utility Model

A connecting cap is arranged at the left end of the valve body, a rubber gasket is arranged inside the connecting cap, a valve stem is arranged inside the top of the valve body, and a first O - ring is arranged between them. Inside the valve body at the top of the valve stem, there are packing and a hexagonal compression nut, as well as a handle clamped to the valve stem.

[0005] As a drainage - type press - fit three - way ball valve of the utility model, preferably, the top of the handle is screwed to the hexagonal compression nut through a hexagonal flange - faced screw, and the rotation of the handle drives the valve stem to rotate.

[0006] As a drainage - type press - fit three - way ball valve of the utility model, preferably, a first valve stem and a compression nut are arranged inside the front end of the valve body, a second O - ring is arranged at the bottom of the first valve stem, and a third O - ring is arranged between the first valve stem and the compression nut.
