The utility model has the advantages that: when the valve clack is opened or closed under the pressure of a medium, the connecting rod rotates between the limiting rods, so that the first roller and the second roller are in rolling connection in the first limiting groove and the second limiting groove respectively, the connecting rod is effectively prevented from deviating, and the sealing property of the valve clack is ensured.
Description
Technical Field
The utility model relates to the technical field of valves, in particular to forged steel check valve.
Background
The forged steel check valve is a valve which automatically opens and closes a valve clack by medium flowing, and is used for preventing medium from flowing backwards, and is also called a check valve, a one-way valve, a backflow valve and a back pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium. Check valves may also be used to provide make-up lines to auxiliary systems where the pressure may rise above the system pressure. The check valves may be largely classified into swing check valves (rotating about the center of gravity) and lift check valves (moving along an axis).
The connecting portion of connecting rod and valve body can take place the skew in long-time use among the current swing check valve, leads to the valve clack also to take place the skew, makes to produce the clearance between valve clack and the sealed face to the leakage has been led to.
