Übersetzung für "Multiport valve" in Deutsch

The outlet valve 205 is configured as a multiport valve.

The invention relates to a gas chromatograph and a multiport valve unit for a gas chromatograph.

Among them, the multiport valve is prioritized as a national patented product.

The multifunction multiport slider valve can be used for fluids and in particular for gaseous media, for example air.

The Ashcroft ® Multiport Gauge Valve-V02 is the ideal valve option for critical applications with demanding requirements.

Preferably, the multiport valve has such a design that the gaseous products can be removed separately.

As a result, the base plate and the multiport valve can have a uniform structure for all valve types.

Standard equipment with next-generation 1 1/2", 6+1 multiport valve from AstralPool.

The multifunction multiport slider valve according to claim 9, wherein the two separate longitudinal sections (29a, 29b) of the casing bore (29) can be fluidically connected or separated by way of the center sealing disc (32a).

However, a 5/3-way valve function is not possible in one and the same valve casing in case of the 5/2-way valve formed by the known multiport valve.

It is an object of the present invention to furnish a multifunction multiport slider valve, i.e. a slider valve, which is formed and constructed to perform a variety of functions, which can be installed at the customer location acquiring the slider valve without large expenditure, and which can be switched by performing only simple adjustments for certain function by the customer himself.

A multiport valve in accordance with claim 1, wherein the restraining piston (30) is loaded with a pre-stressing spring (48) on its side facing the control chamber (46).

The multiport valve 116 (“on/off vent valve”), which connects the supply for oxygen to the bypass line 120 which leads past the fuel cell 10 and opens into the surrounding atmosphere, is located downstream of the pressure regulation valve 114 .

Here it is also possible for the delivery line to have a multiport valve, by means of which the inlet to the two volumes can be controlled.

The outlet valve 5 is configured in this case as a multiport valve and can connect the sample chamber 4 and the second pump 2 to the first outlet 6 or to the second outlet 7 .

The reactor is advantageously provided with a multiport valve to enable the supply of the gaseous educts.

The multiport valve unit comprises ten controllable valves, which are connected in series and are open or closed depending on their activation.

In each case, immediately adjacent valves of the series circuit are activated here in a different manner, so that the multiport valve unit has two different switching positions, in which each second valve is either closed or open.

To terminate the sample dosing in the carrier gas stream, the valves 15, 16, 17, 18, 19 of the first series circuit 20 are once again switched, so that the multiport valve unit 14 again assumes the first switching position (FIG. 1).

The flow resistances 28, 29 serve to pneumatically balance the system in the different switching positions of the multiport valve unit 14 .

Here, the ports 36, 37, 38 are additionally extended through the multiport valve unit 14 as far as the outer surface of the upper part 52 facing away from the diaphragm 49, in order to enable the attachment of the flow resistance 28 there to the carrier gas feed 6, of the second separating device 9 with its associated detector 10 to the gas outlet 11 and of the flow resistance 29 to the gas outlet 12 .
