Abstract
The utility model discloses a valve element seat of a safety valve. The valve element seat of the safety valve comprises a seat body, wherein a groove used for installing an O-shaped sealing ring in a sleeved mode is formed in the middle of the periphery of the seat body, a stand column integrated with the seat body is arranged in the middle of the upper end of the seat body, a circle of annular groove is formed outside the stand column, at least one spring pressing block is arranged at the bottom of the annular groove, and clamp spring grooves are machined in the seat body and located in the upper end and the lower end of the groove respectively. The valve element seat of the safety valve has the advantages that the design that a valve rod and the valve element seat are integrated is adopted, and the sealing ring is installed around the valve element seat and is clamped through clamp springs, so that the valve element seat is high in production and machining efficiency. The safety valve provided with the valve element seat has the advantages of being convenient to install and detach, rapid to repair and the like.
