Description
Technical Field
The utility model relates to the technical field of valves, specifically a but manual control's vertical check valve.
Background
The check valve is a valve whose opening and closing part is a circular valve clack and acts by its own weight and medium pressure to block the medium from flowing backwards, and belongs to the automatic valve class, also called check valve, one-way valve, backflow valve or isolating valve. The valve clack motion mode is divided into lifting type and swing type. The medium of the lifting check valve flows in from the inlet end (lower side) and flows out from the outlet end (upper side), when the inlet pressure is larger than the sum of the weight of the valve clack and the flow resistance thereof, the valve is opened, otherwise, the valve is closed when the medium flows backwards.
The traditional vertical check valve is simple in structure, when a medium flows back, no power is provided for closing the valve clack, only the pressure of the medium is relied on, and due to the vertical structure, the non-return effect is not ideal, so that optimization is needed.
