一种阀座及采用该阀座的球阀

Valve base and ball valve with same

Abstract

本实用新型公开了一种阀座及采用该阀座的球阀,属于阀门技术领域;所述阀座包括阀座体,阀座体上设置有弹性片,所述阀座体和弹性片为一整体结构,弹性片端部设置有工作密封面;本实用新型的阀座设计巧妙、结构简单合理,利用介质的压力推动阀座的弹性片与阀芯球面可靠密封,具有介质压力越大密封越可靠的优点,解决了高压差、高泄漏要求的密封难题;所述阀座装配时阀芯和阀座的密封面轻松接触接,采用流开安装,因此阀门打开时轻松灵活,不会有启跳现象产生,执行器力矩小、成本低,相对于传统的流闭安装设计,克服了在高温工况时阀芯和阀座容易咬合而产生卡死的现象。
The utility model discloses a valve base and a ball valve with the valve base, and belongs to the technical field of valves. The valve base comprises a valve base body. An elastic piece is arranged on the valve base body. The valve base body and the elastic piece are of an integrated structure. A working sealing face is arranged at the end of the elastic piece. The valve base is ingenious in design and simple and reasonable in structure, pressure of media is utilized for pushing the elastic piece of the valve base to be in reliable sealing connection with the spherical surface of a valve element, the valve base has the advantage that the larger the pressure of the media is, the more reliable the sealing is, and the sealing problem with high pressure difference and high leakage is solved; when the valve base is assembled, the sealing faces of a valve element and the valve base are easily in contact, and flow-open installation is adopted, so that the valve is opened easily and flexibly, no starting tripping phenomenon is generated, the torque of an actuator is small, the cost is low, and the phenomenon that the valve element and the valve base are prone to occlusion and clamping on the high-temperature working condition is avoided compared with the traditional flow-closed installation design.
