spring type brass check valve refers to a valve whose opening and closing part is a circular disc and acts by its own weight and medium pressure to block the backflow of the medium. 1 spring check valve is an automatic valve, also known as a check valve, a one-way valve, a return valve or an isolation valve. The movement mode of the 4 spring check valve disc is divided into lift type and swing type. The lift check valve is similar in structure to the globe valve, except that it lacks the valve stem that drives the valve disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back. The spring check valve has a disc that is inclined and can rotate around the axis, and the working principle is similar to that of the lift vertical brass check valve. The check valve is often used as the bottom valve of the pumping device, which can prevent the backflow of water. The check valve is used in combination with the globe valve, which can play the role of safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed
