Problems solved by technology

[0002] The existing valve driving device is directly connected to the valve body. For the scene where the installation and operation space of ship equipment is relatively limited, the application of large-diameter valves has certain limitations, especially the arrangement of the valve driving device.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] The present invention connects the valve body and the driving device by adopting a universal coupling. Since the installation position of the driving device is far away from the valve, the universal coupling has the characteristics of axial expansion and joint swing angle, which can effectively ensure The connection between the valve body and the driving device is realized to realize the long-distance transmission control of the valve and the valve opening and closing function; at the same time, in order to effectively fix the driving device, a support frame is designed. The thermal expansion of the universal joint, the axial expansion and contraction of the universal coupling and the compensation of the swing angle of the two joints can effectively eliminate the influence of thermal expansion on the action of the actuator. The valve structure is as follows: fig...

Abstract

The invention belongs to the technical field of ship equipment, and particularly relates to a novel valve driving structure for a limited space. The novel valve driving structure comprises an isolating valve body 1, a locking device 2, a universal coupler 3 and an executing mechanism 4; the isolating valve body, the locking device, the universal coupler and the executing mechanism are sequentially connected together, the universal coupler is of a two-section type design, and the universal coupler has axial stretching and joint swing angles. The valve body and the driving device are connected through the universal coupler, due to the fact that the installation position of the driving device is far away from a valve, and the universal coupler has the characteristics of axial stretching and joint swing angle, butt joint of the valve body and the driving device is effectively guaranteed, remote transmission control over the valve is achieved, and the valve opening and closing function is achieved.

Description

technical field [0001] The invention belongs to the technical field of ship equipment, and in particular relates to a novel valve driving structure for limited space. Background technique [0002] The existing valve driving device is directly connected to the valve body. For the scene where the installation and operation space of ship equipment is relatively limited, the application of large-diameter valves has certain limitations, especially the arrangement of the valve driving device. Contents of the invention [0003] The object of the present invention is to provide a novel valve driving structure for limited space. [0004] The purpose of the present invention is achieved like this: [0005] A new type of valve drive structure for limited space, including a block valve body 1, a locking device 2, a universal coupling 3, and an actuator 4, and the valve body, locking device, universal coupling, and actuator are connected in sequence Together, the universal coupling i...
