超低温热循环式安全阀Cryogenic Thermal Relief Valve

派克Bestobell的紧凑型超低温安全阀是为了防止液化气汽化成气体膨胀，压力升高引起管道和设备的损坏。 Parker Bestobell's cryogenic thermal relief valve is designed to prevent damage to piping and equipment caused by the expansion of liquefied gases. It prevents liquefied gases being trapped between two closed valves.

派克Bestobell的紧凑型超低温安全阀是为了使液化气不发生汽化成气体膨胀，压力升高引起管道和设备的损坏。这热循环安全阀将在+/-3%额定压力时提升打开。当液化气体被困在两个关闭的阀门之间时（称为液锁），此时介质会汽化可导致压力上升，管道内压力升高比较危险。派克Bestobell热循环阀被设计来不增加压力。 Parker Bestobell's compact cryogenic thermal relief valve is designed to prevent damage to piping and equipment caused by the expansion of liquefied gases. This thermal relief valve will lift at =/- 3% of set pressure rating. When liquefied gases are trapped between two closed valves (known as liquid lock), reheating and boiling can lead to a dangerous rise in pressure. The Parker Bestobell's thermal relief valve has been designed to prevent pressure build up.

其稳定的设计意味着阀不会粘在座位上，即使这个阀门已经有很长时间未使用。当泄放掉膨胀后的气液介质后，该阀门复位正确，从而有效减少了燃气的浪费。它可与多种出口连接，以满足客户的要求。 Its tried and trusted design means that the valve will not stick in its seat, even when it has been left unused for long periods of time. The valve also reseats correctly after venting off the expanding fluid, thus preventing gas wastage. It is available with a variety of outlet connections to suit customer requirements.
