Description

shunt device

The present invention relates to a pipeline component, in particular to a diverter device.

Referring to Figure 1, a conventional flow diverting device is to install a plurality of valves 1 on a manifold (not shown).

The manifold has an input pipe part and a plurality of output pipe parts connected with the input pipe part and provided with the valves 1 .

Each valve member 1 has a body 11 and a valve body 12 disposed on the body 11 and used to control the conduction status of the body 11 . The body 11 has an input flow channel 111, an output flow channel 112, and a valve flow channel 113 meanderingly connected between the input flow channel 111 and the output flow channel 112. The valve body 12 has a The control film 121 of the flow channel 113 and a driving rod 122 that drives the control film 121 to deform.

The driving rod 122 can be controlled to drive the control membrane 121 to change between a blocking state and a non-blocking state. In the blocking state, the control membrane 121 blocks the valve flow channel 113 downward to allow the input flow The channel 111 and the output flow channel 112 are not connected. In the unblocked state, the control film 121 rebounds upward to make the input flow channel 111 The output flow channel 112 is connected through the valve flow channel 113 .

When the fluid flows from the input pipe to the output pipe of the manifold, it will flow into the valves 1. By controlling the driving rods 122 of the valves 1 to change between different states, the fluid can be The manifold and the valves 1 achieve the effect of diverting flow.

However, when a first fluid is used for flow splitting, due to the curved shape of each valve channel 113, part of the first fluid or reactant will remain in the valve channels 113. Therefore, if a second fluid is then used, When the fluid is divided, the second fluid will be contaminated and its quality will be affected.

In addition, the number of output pipe parts of the manifold is fixed. If you want to change the number, you must purchase a new appropriate number and match the corresponding valve 1, which is very inconvenient.

Therefore, the purpose of the present invention is to provide a diverter device that overcomes the shortcomings of the prior art.

Therefore, the new diverter device includes a diverter unit and at least one pressure cylinder unit.

The flow splitting unit includes an input part and at least one output part. The input part has an input channel. The at least one output part has a piston channel connected to the input channel, and a piston channel surrounding the piston channel adjacent to the input channel. The side shoulders surround the wall, a The at least one pressure cylinder unit is connected to the piston surrounding wall that defines the side of the piston channel away from the input channel and has an inner diameter larger than the inner diameter of the shoulder surrounding wall, and an output channel connected to the piston channel. It includes a cylinder disposed outside the piston channel and surrounding a cylinder space connected to the piston channel, and a piston member movably passing through the piston channel and the cylinder space, and the piston member can be driven. Moves between a closed position and a conductive position. When in the closed position, the piston member presses against the shoulder surrounding wall so that the input channel and the piston channel are not connected. When in the conductive position, the piston member Surrounding the wall away from the shoulder is such that the input channel communicates with the output channel through the piston channel.

The function of the present invention is that by arranging the input channel, the piston channel and the output channel of the at least one output part, and the at least one pressure cylinder unit, the input channel and the output channel of the at least one output part are The spaces can be connected or disconnected under control to achieve the effect of diversion.
