Description
Technical Field
The invention relates to the technical field of control valve research, in particular to an adjustable novel check valve component and machining equipment.
Background
The check valve is also called a check valve, a one-way valve, a reverse flow valve or a one-way valve, and the check valve is used for preventing the medium from flowing backwards. The valve clack of the check valve is opened under the action of fluid pressure, fluid flows from the inlet side to the outlet side, and when the pressure of the inlet side is lower than that of the outlet side, the valve clack is automatically closed under the action of the fluid pressure or self gravity to prevent the fluid from flowing backwards. The check valve is an automatic valve, is mainly used on a pipeline for unidirectional medium flow, and only allows the unidirectional medium flow to prevent accidents. When the check valve is in the closed state, the valve flap needs to be in sealing engagement with the valve body to prevent fluid leakage.
However, the following is likely to occur during use of the check valve:
1. when the valve clack is opened completely, the liquid flow pressure generates large impact force on the valve body, impact damage is generated on the valve body, impact noise is large when the valve clack is opened, and the opening and closing amplitude and the movement speed of the valve clack are too high, so that the valve clack and the valve body collide violently easily to cause damage.
2. The liquid medium is easy to generate backflow, and the backflow is mainly caused by the following aspects: the sealing surface is damaged; impurities are clamped; the corrosion or skew of the guide groove results in the failure of the valve flap to fall back normally (lift check valve). Sealing surface repairing and impurity removal can prevent backflow. The guide groove is polished by abrasive cloth, and the valve clack is required to be aligned when the guide groove is additionally arranged.
The check valve is a valve for controlling the unidirectional flow of the medium in the pipeline and is used for preventing the medium in the pipeline from flowing backwards. The valve plate is automatically opened and closed by the force generated by the flowing of the medium in the pipeline, the valve plate is an important component of the check valve, and the existing valve plate processing equipment is low in processing efficiency, large in cost investment, not suitable for batch production and urgent to improve.
