Overview

Stacked relief valve is a hydraulic pressure control valve. It mainly plays a role in constant pressure overflow and safety protection in hydraulic equipment. Constant pressure overflow effect: In the quantitative pump throttling regulation system, the quantitative pump provides a constant flow rate. When the system pressure increases, it will reduce the flow demand. At this point, the overflow valve is open,

Product Details

A stacked overflow valve is composed of an overflow valve insert and a stacked valve body. The overflow valve insert consists of a valve seat, a valve core, a pressure regulating spring, etc. The valve core is conical and extends a cylindrical body to the right of the valve seat inlet. The cylinder body is equipped with a cylindrical blind hole connected to the valve seat inlet; A cylindrical section extends from the right end of the valve core cone, and the outer side of the cylindrical section of the valve core is also provided with an axial spiral groove This utility model adopts a combination of a cylindrical section of the valve core and a blind hole in the cylinder of the valve seat for guidance, so that the cone seal between the valve core and the valve seat will not undergo radial displacement, ensuring reliable sealing without leakage; Adding damping formed by axial spiral grooves on the outer side of the cylindrical section of the valve core ensures stable pressure; Not only can it be used as a general direct acting relief valve, but it can also be used as a safety valve for stacked installation
