安全阀的阀芯
摘要：
本发明公开了一种安全阀的阀芯，包括沿轴向依次设置的进液段和导向段，进液段上设有沿轴向依次布置的第一过液孔、第二过液孔、第三过液孔和第四过液孔，第一过液孔和第二过液孔用于将进入阀芯内的液体引导至安全阀的第一排液孔且第一过液孔和第二过液孔为错开布置，第三过液孔和第四过液孔用于将进入阀芯内的液体引导至安全阀的第二排液孔且第三过液孔和第四过液孔为错开布置。本发明安全阀的阀芯，第一过液孔和第二过液孔、第三过液孔和第四过液孔分别采用错开的方式进行布置，在提高过液流量的同时，可以增加阀芯的金属性能，提高阀芯的刚度，使得阀芯不容易断裂；阀芯的过液流量大，有利于提高安全阀的排液流量，提高了安全阀的卸荷能力。
摘要（英）：

The invention discloses a valve element of a safety valve. The valve element comprises a liquid incoming section and a guide section which are axially arranged sequentially, a first liquid passing hole, a second liquid passing hole, a third liquid passing hole and a fourth liquid passing hole which are axially arranged sequentially are formed in the liquid incoming section, the first liquid passing hole and the second liquid passing hole are used for guiding liquid entering the valve element to a second liquid discharging hole of the safety valve, and the third liquid passing hole and the fourth liquid passing hole are in staggered arrangement. The first liquid passing hole, the second liquid passing hole, the third liquid passing hole and the fourth liquid passing hole are in staggered arrangement, so that liquid passing flow is increased, metal performance of the valve element is improved, rigidity of the valve element is improved, so that the valve element is less prone to breaking; the valve element is large in liquid passing flow, so that increasing of liquid discharging flow of the safety valve is facilitated, and unloading capacity of the safety valve is improved.
