Embodiment Construction

[0044] The technical scheme of the present invention is described more specifically below in conjunction with accompanying drawing and embodiment:

[0045] The present invention includes a first four-way ball valve 10 and a second four-way ball valve 20. A first valve core 11 is arranged in the valve body cavity of the first four-way ball valve 10, and a first valve core 11 is arranged in the valve body cavity of the second four-way ball valve 20. There is a second spool 21 , the first spool 11 and the second spool 21 are fixedly connected and rotate synchronously under the action of the driving mechanism 30 to realize synchronous switching of the fluid flow direction. According to the present invention, the first valve core 11 and the second valve core 21 are fixedly connected and can rotate simultaneously under the action of the driving mechanism 30, that is, the structure can control the first four-way ball valve 10 and the second four-way ball valve. 20 The flow direction ...

Abstract

The invention relates to a series four-way ball valve group. The series four-way ball valve group comprises a first four-way ball valve and a second four-way ball valve; a first valve element is arranged in a valve cavity of the first four-way ball valve, a second valve element is arranged in a valve cavity of the second four-way ball valve, and the first valve element and the second valve element are fixedly connected and synchronously rotate under the effect of a drive mechanism to achieve synchronous switching of the flow direction of fluid; the first valve element and the second valve element are fixedly connected and can rotate at the same time under the effect of the drive mechanism, through the structure, the flow directions of the fluid in the first four-way ball valve and the second four-way ball valve are switched at the same time, consistency of actions of the first valve element and the second valve element is ensured, and the interlocking function of the first valve element and the second valve element is achieved.

Description

technical field [0001] The invention belongs to the technical field of four-way ball valves, in particular to a series four-way ball valve group. Background technique [0002] The dryer is the core equipment of the catalytic reforming unit, which requires high manufacturing precision and operational reliability, and most of the domestic in-service products are imported. The series four-way ball valve group in the dryer is the key equipment for switching the flow direction of the medium in the dryer circulation circuit, but the two four-way ball valves in the existing equipment do not have an interlock function, and the action consistency is poor. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a series four-way ball valve group, which has an interlocking function and consistent action, and is especially suitable for the circulation circuit of the dryer in the catalytic reforming device. [0004] In order to...
