Description

Technical Field

[0001] The utility model relates to a pipeline connecting valve seat, in particular to a two-way valve seat for chromatography degradation. Background Art

[0002] Pipelines are required in chromatographic degradation, and the connection between pipelines is generally achieved through a valve seat, thereby achieving fluid communication between the pipelines. In one prior art, the valve seat includes a valve seat body, a first connecting pipe, and a second connecting pipe. The valve seat body is provided with an inner cavity for fluid circulation. The first connecting pipe and the second connecting pipe are both fixedly connected to the valve seat body, and the first connecting pipe and the second connecting pipe are both connected to the inner cavity of the valve seat body. The first connecting pipe is connected to one pipeline, and the second connecting pipe is connected to another pipeline, thereby achieving fluid communication between the two pipelines. However, this valve seat can only achieve simple fluid communication, but cannot control fluid separation control and liquid sampling, and these two functions are currently in short supply in the market.

[0005] Furthermore, the outer surface of the partition is flush with the plane where the outer contour of the first separation cavity is located and the plane where the outer contour of the second separation cavity is located, so that the partition prevents the first separation cavity and the second separation cavity from communicating, thereby achieving the purpose of separating and controlling the fluid.

[0006] Furthermore, it also includes a sampling pipeline, which is fixedly connected to the valve seat body and has a sampling through hole.

[0007] Furthermore, the sampling through hole passes through the valve seat body, and the sampling through hole is communicated with the sampling port, so that the sampling through hole is communicated with the sampling chamber.

[0008] Furthermore, the valve seat body is provided with a connecting portion, and the connecting portion is provided with a preset number of threaded connecting holes.

[0009] Furthermore, the first communicating pipe is fixedly connected to the valve seat body by welding, screw / bolt connection, clamping, snap connection or integral molding.

[0010] Furthermore, the first communicating pipe 3 is fixedly connected to the valve seat body by welding, screw / bolt connection, clamping, snap connection or integral molding.

[0011] Furthermore, the sampling pipe is fixedly connected to the valve seat body by welding, screw / bolt connection, clamping, snap connection or integral molding.

[0012] The beneficial effects of the present application are as follows: the present application provides a two-way valve seat for chromatographic degradation, which has a simple structure and is easy to manufacture. In addition, since a first separation chamber and a second separation chamber are provided on the valve seat body, fluid separation control can be achieved; and a sampling through hole is provided on the valve seat body, so that the liquid flowing through the valve seat body can be sampled more simply during the chromatographic degradation process.
