Übersetzung für "Pressure retention valve" in Deutsch

The pressure in the second reaction vessel is regulated via a pressure-retention valve.

The product is discharged from the apparatus via a pressure retention valve.

A plug valve is particularly preferred as pressure-retention valve.

The pressure retention valve keeps the filter housing constantly under pressure.

The pressure in the reactor and in the scrubber column was held constant at 4 bara by way of a pressure-retention valve.

The gaseous reaction products can be separated off from the reaction mixture by letting down or via a pressure retention valve.

Equipping the SECCANT regeneration dryer with a compatible pressure retention valve safeguards the minimum pressure in the filter housings.

The to maintain a constant pressure of 110 bar in the tubular reactor was adjusted by means of the pressure retention valve 7 .

The to maintain the constant pressure needed for the supercritical carbon dioxide is adjusted by means of the pressure retention valve 7 .

To generate permeate pressure, a pressure retention valve (199) is used with a permeate flushing valve (34).

Then the mixture is heated to 280° C., wherein the pressure increase beyond the condenser is restricted to 3 bar by means of the pressure retention valve.

2,550 kg (27.4 kmol) of aniline and 2,180 kg (15.2 kmol) of 1-naphthylamine were introduced to a high pressure autoclave made of V4A, which was provided with a condenser, a coiled condenser connected in series and beyond that a pressure retention valve.

Heating was performed in a controlled manner so that only small amounts of a mixture of ammonia, aniline and water constantly distilled off via the head, while the rise in pressure due to the ammonia gas being produced was restricted by means of the pressure retention valve set at 2.5 barabs connected beyond the cooling system.

At the end of the continuous reactor, the almost completely reacted mixture is conducted, via a discharge or pressure-retention valve and collected in a steel tank.

At the end of the tube, the reacted reaction solution is, shortly after the oil bath, conveyed via a discharge or pressure-retention valve set to 20 bar and a cooling section into a 3 liter steel tank which is connected via a safety valve to a scrubber (cooling water).

In another preferred embodiment of the invention, the pressure of the vapor mixture from the second reaction vessel is released via a pressure-retention valve into the scrubber and this is operated at a pressure of from 0.8 to 1.5 bara.

The scrubbed vapor mixture is condensed at the head of the scrubber at atmospheric pressure, if desired after passing through another pressure-retention valve, and discharged.

In the simplest case, the process according to the invention is carried out in a closed vessel under the pressure established by itself or under the pressure determined by a pressure retention valve.

Advantageously, the second valve is a pressure retention valve while the first valve is an electrically actuated valve.

Preferably immediately upstream of the inlet 12 of vacuum chamber 13, in a second line section 10 of the connecting line 8 / 10 that connected to the first line section 8, there is a relief valve 11 that also acts as a pressure retention valve for a system pressure p to be maintain upstream of the relief valve 11 in the line sections 8, 10 (see FIGS. 1 b, 1 a).
