Embodiment Construction

[0032] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0033] figure 1 It is a schematic diagram of a cross-section of a hose section according to an embodiment of the present invention, and numeral 10 indicates that the hose section is in an unaffected state; The valve element, at this time, the valve device is in the normally open state (NO). It can be understood that, in the present invention, the hose segment is also referred to as an elastic member.

[0034] figure 2 A schematic cross-sectional view of a hose section according to an embodiment of the present invention, numeral 20 indicates the hose section in an unaffected state, and numeral 21 indicates the hose section in an expanded state.

[0035] In one embodiment of the present invention, the valve device includes: at least two elastic parts, each elastic part has at least one elastic region; at least one valve seat cor...

Abstract

The invention relates to a device for controlling fluid flow in a fluid channel, and discloses a valve and a flow control method. The flow is controlled by the hose and the compression of the hose segments (10, 11) along the length of the hose, whereupon the elastomer is folded towards the circular wall.

Description

technical field [0001] The present invention relates to a valve and more particularly to a valve arrangement for mechanically controlling the flow of at least one fluid through at least one channel. Background technique [0002] When designing low-pressure valves, especially those used in the gas control field of ventilators, it is very important that the fluid path requires low flow resistance and no turbulence. Some applications require high attention to cleaning of contaminated parts of the valve. Furthermore, valves generally need to be designed to be small and light, so that the actuators controlling the valves can be made small and unaffected by the fluid passages. [0003] Examples of low pressure valve applications are exhalation valves, pressure relief valves for patients, mixing valves and flow valves in low pressure systems. [0004] Current low-pressure valve designs typically place a disc at the end of the hose that forms the seat. An example of such a design...
