Description

Intelligent quick-opening slow-closing check valve with inclined seat
Technical Field
The utility model relates to the technical field of check valves, in particular to an intelligent inclined seat quick-opening and slow-closing check valve.
Background
The check valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards. It belongs to the automatic valve category, also called check valve, reflux valve or isolation valve. The motion mode of the valve clack is divided into a lifting type and a swing type. The lift check valve is similar in structure to the stop valve and only lacks a valve rod that drives the valve flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. Swing check valves have a flap that is tilted and can pivot, and operate on a similar principle to lift check valves. The check valve is commonly used as a bottom valve of a water pumping device and can prevent the backflow of water.
Some check valves on the existing market are just beginning to install the operation at the water pump, perhaps user's volume is not big, and the water pump is opened, and discharge is less, and inlet pressure is not enough in making the valve open completely, and the valve only opens partly like this, and valve plate opening angle is little, leads to rivers little, head loss big, and in the twinkling of an eye of stopping the pump, because the valve closing speed is very fast, arouses destructive water hammer easily.
We have therefore proposed an intelligent inclined seat quick-opening slow-closing check valve in order to solve the problems set forth above.
