Single-pole dual-switch multi-position valve

Abstract

A single-pole dual-switch multi-position valve comprises a valve body, a disc body, a first valve plate, a first sliding rail, a first sliding pin, a first supporting pole, a touch point, a middle seat, a pivot point, a valve pole, a transmission pin, a second supporting pole, a second sliding rail, a third sliding rail, a second sliding pin, a second valve plate, a handle and a driving part. According to the single-pole dual-switch multi-position valve disclosed by the invention, a single pole is adopted for controlling multiple valve plates; the sliding rails are applied to actuation, and the situation that the single pole controls the switching on and off of the multiple valve plates in sequence can also be realized while the multiple valve plates are controlled by the single pole; the single-pole dual-switch multi-position valve comprises the touch point which is matched with the sliding pins, closing is firm, and one-way opening is realized; the valve pole and an actuation part can move manually, so that the operation flexibility is increased.

Description

technical field [0001] The invention relates to the field of fluid control, in particular to a single-rod double-open multi-position valve. Background technique [0002] Existing poppet valves or gate valves or flap valves or discharge valves are generally single-rod control single-disc valves, which are difficult to adapt to complex working conditions when encountering complex requirements. However, one valve stem controls multiple valve plates, which is cumbersome and can only be adapted to symmetrical low-demand conditions. [0003] Existing poppet valves or gate valves or flap valves or discharge valves generally can only be opened or closed once, which is difficult to adapt to complex working conditions. The multi-position control of a valve stem can only adapt to simple working conditions, such as multi-way valves. [0004] The slide rails in the prior art are only used for transmission, not for driving. Contents of the invention [0005] In order to overcome the ...

Problems solved by technology

[0002] Existing poppet valves or gate valves or flap valves or discharge valves are generally single-lever-controlled single-disc valves, which are difficult to adapt to complex working conditions when encountering complex requirements

However, one valve stem controls multiple valve plates, which is cumbersome and can only be adapted to symmetrical low-demand conditions.

[0003] Existing poppet valves or gate valves or flap valves or discharge valves generally can only be opened or closed once, which is difficult to adapt to complex working conditions

However, the multi-position control of a valve stem can only adapt to simple working conditions, such as multi-way valves, etc.

[0004] In the prior art, the slide rail is only used for transmission, not for driving
