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, and specifically relates to a series four-way ball valve group. Background technique

[0002] The dryer is the core equipment of the catalytic reforming unit, and its manufacturing accuracy and operational reliability are required to be high. Most of the domestic products in service are imported. The series four-way ball valve group in the dryer is a key device for switching the flow direction of the medium in the dryer's circulation loop. However, the two four-way ball valves in the existing such equipment do not have the interlocking function and the action consistency is poor. Summary 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 has consistent action, and is especially suitable for the circulation loop of the dryer in the catalytic reformer.

Embodiment Construction

[0044] The technical solution of the present invention will be described in more detail below in conjunction with the drawings and embodiments:

[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 provided in the valve body cavity of the first four-way ball valve 10, and a valve body cavity of the second four-way ball valve 20 is provided There is a second valve core 21, and the first valve core 11 and the second valve core 21 are fixedly connected and rotate synchronously under the action of the driving mechanism 30 to realize the synchronous switching of the fluid flow direction. The first valve core 11 and the second valve core 21 of the present invention are fixedly connected and can be rotated simultaneously under the action of the driving mechanism 30, that is, the structure can be used for the first four-way ball valve 10 and the second four-way ball valve. 20 The fluid flow direction in the va...
