The invention relates to a spherical sealed ash relief valve, which comprises an electro-hydraulic push rod, a crank connecting rod, a valve cover, a sealing ring and a seat. One end of the crank connecting rod is connected with the piston rod of the electro-hydraulic push rod, the other end is connected with the spherical valve cover through threads, the middle part of the crank connecting rod is movably arranged on the valve seat through a rotating shaft, the valve cover is a spherical valve cover, and the lower end of the valve seat is also provided with a sealing ring. The sealing ring is installed in the sealing ring positioning seat, and the sealing ring is made of wear-resistant elastic material. After adopting the above structure, the hydraulic oil is rotated by the motor to output the pressure oil through the bidirectional gear pump and sent to the working cylinder through the oil circuit integrated block to realize the reciprocating motion of the piston rod. The utility model has the advantages of large execution force, stable working state and strong pressure-holding function, which can ensure the sealing effect and improve the reliability and stability of the seal.

一种球形密封卸灰阀
本专利技术涉及一种球形密封卸灰阀。
技术介绍
现有技术中真空脱气精练系统的气体冷却器卸灰阀,主要由气缸、连杆、阀盖、O型密封圈、阀座组成。卸灰时,气缸活塞杆回缩,带动连杆绕着转轴顺时针旋转,阀盖打开;卸灰完毕,气缸活塞杆推出,带动连杆围绕转轴作逆时针旋转,阀盖与阀座压紧,通过O型密封圈进行密封。因为气体冷却器的卸灰口排出来的是水灰混合物,而且排放频率较高,所以湿灰经常粘在卸灰阀阀座的平面法兰的密封面和O型密封圈上,加上阀座与O型密封圈为线型正压式接触,无法自行清理密封面上粘结的粉尘,从而无法保证密封的接触面积,致使密封失效,因此,在每次放灰后都必须进行密封位置的人工清理,造成了真空度下降、处理初期到达目标真空度时间长、真空泵混合室本体异常磨损、扩压段积灰严重等严重故障,大大影响了真空脱气精练的质量和产量。
