HENRY泄壓閥介紹

The function of a Pressure Relief Valve is to protect against over-pressure. For safety reasons, excessive over-pressure in any part of the refrigeration system must be avoided

Applications

A typical application for a Henry Technologies pressure relief valve (PRV) is to protect a liquid receiver from being over-pressurised. In the event of a fire, any liquid refrigerant inside the receiver will evaporate resulting in an increase in pressure. The PRV will safely control this increase in pressure by venting the vapour from the receiver. Another application is to protect equipment from compressor over-pressure.

Henry Technologies pressure relief valves are designed to discharge vapour and should not be used to vent liquid refrigerant. The valves are “back-pressure dependent” and are therefore required to discharge to atmosphere.

The brass and stainless steel series valves are suitable for use with HCFC and HFC refrigerant gases. The stainless steel series valves are also suitable for ammonia.

Once a PRV has discharged, replacement is recommended, as the set pressure can no longer be guaranteed. Refer to Installation Section for further information.

In line with the Institute of Refrigeration Guidelines (UK), Henry Technologies recommend that a PRV should be replaced at least every 5 years. These intervals may have to be reduced if other regulations apply.

It is recommended to have a relief valve pressure setting at least 25% higher than the maximum system operating pressure. The PRV set pressure should not be higher than the design pressure (MWP) of the vessel.

泄壓閥的功能是防止過壓。 出于安全原因，必須避免制冷系統任何部分的壓力過高

應用領域

Henry Technologies 泄壓閥 (PRV) 的典型應用是保護液體接收器免遭過壓。 如果發(fā)生火災，接收器內的任何液體制冷劑都會蒸發(fā)，導致壓力增加。 PRV 將通過從接收器排出蒸汽來安全地控制壓力的增加。 另一個應用是保護設備免受壓縮機過壓的影響。

Henry Technologies 泄壓閥設計用于排放蒸汽，不得用于排放液體制冷劑。 這些閥門是“背壓相關的”，因此需要排放到大氣中。

黃銅和不銹鋼系列閥門適用于 HCFC 和 HFC 制冷劑氣體。不銹鋼系列閥門也適用于氨。

一旦減壓閥泄壓，建議更換，因為無法再設定壓力。請參閱安裝部分了解更多信息。

根據英國制冷協會指南，Henry Technologies 建議至少每5年更換一次PRV。 如果其他規(guī)定適用，這些間隔可能必須縮短。

建議安全閥壓力設置至少比最大系統工作壓力高 25%。PRV設定壓力不應高于容器的設計壓力（MWP）。
