Description

Guide nail suitable for valve plate positioning connection

Technical Field

The utility model relates to a valve plate location technical field especially relates to a guide pin suitable for valve plate location links up.

Background

Fasteners are a generic term for a class of mechanical parts used to fasten two or more parts (or components) together as a unit. Screws and pins are the two most widely used types of fasteners, and guide pins add a guiding effect to the valve plate, which is the material that makes up the valve assembly, and is generally flat or nearly flat, on the basis of the pins, thereby enabling the valve plate to rotate in a directional manner. It needs to be durable and strong and in many cases also resistant to heat, pressure and corrosion.

When traditional direction nail links up the valve plate, only can play the fixed action to the valve plate, can't make the valve plate rotate to its unable automatic re-setting after the valve plate rotates needs the manual work to come to reset the valve plate, and very consumeing the manpower, thereby makes work efficiency reduce, consequently need be applicable to the direction nail that the valve plate location links up.
