Relief Valve
To ensure safety, the drilling pump is equipped with a safety valve in the outlet, which is able to control the ultimate pressure of the pump within the admitted scope.
The high-pressure safety valve is forged by high-quality structural alloy steel. As a kind of protection device and human safety device, it is generally installed on cementing devices, fracturing pumps, high-pressure operation piping, pressure vessel and devices under high pressure and high flow capacity. It controls the elastic force of the valve seat by adjusting the nut on the top. Once the pumping pressure or piping pressure exceeds the pre-established pressure value, the safety valve opens automatically to release the pressure. When the pressure value reaches the normal value, the valve rod will recover the position by spring and close the valve.
