Work method of single-pole bipartition multiposition valve

Abstract

The invention discloses a work method of a single-pole bipartition multiposition valve. When the single-pole bipartition multiposition valve is closed, a first sliding pin is located at the left end of a first sliding rail, a second sliding rail is located at the right end of a third sliding rail, and a first supporting rod and a second supporting rod are located at the bottom point; when the valve is opened, firstly a driving part is manipulated to drive a valve rod to lift to the first position, at this moment, the first sliding pin is run to the right side of the first sliding rail to press a contact spot and make the touch spot retracted, a first valve plate is opened, after the valve plate is opened, the touch spot pops up, the first sliding pin drives the first valve plate to lift, and a second sliding pin is run to the middle section of the second sliding rail through a third sliding rail; afterwards, the driving part is manipulated to drive the valve rod to lift to the second position, at this moment, the second sliding pin is run to the upper end of the second sliding rail, the second valve plate is driven to lift, and is opened, at this moment, the two valve plates are opened simultaneously, and the first valve plate and the first supporting rod are in the linear state.

Description

technical field [0001] The invention relates to the field of fluid control, in particular to a working method of 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 or...

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
