Damping type valve seat of check valve
Technical Field
The invention relates to a valve seat, in particular to a damping valve seat of a check valve, and belongs to the technical field of check valve application.
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 valve clack motion mode is divided into lifting type and 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 check valve is commonly used as a bottom valve of a water pumping device and can prevent the backflow of water. The check valve and the stop valve are combined for use, and the safety isolation effect can be achieved.
When the check valve is installed and used, need use the disk seat to assist fixedly to installing the check valve at the operating position, guarantee the stability of check valve installation, but current check valve disk seat general structure is comparatively simple, when the disk seat receives outside vibrations striking, can transmit the check valve body with the effort that outside vibrations striking was applyed to the disk seat on high-efficiently, make the check valve receive the effort influence and take place vibrations, influence the work of check valve, can make the junction of check valve and foreign object receive serious damage, can subtract the life of short check valve.
