Technical Field
The invention belongs to the technical field of valve equipment, and particularly relates to a high-pressure hedging type regulating valve.
Background
The regulating valve is a valve which reduces the inlet pressure to a certain required outlet pressure through regulation and leads the outlet pressure to be automatically kept stable by depending on the energy of the medium. From the viewpoint of hydrodynamics, the regulating valve is a throttling element with variable local resistance, namely, the flow velocity and the kinetic energy of fluid are changed by changing the throttling area, so that the purpose of regulating the flow is achieved.
Traditional governing valve is the structure of simple valve clack and valve rod only, and the valve rod is connected the valve clack and provides the power of opening and close for the operation of valve clack, but because the effect of medium power for the closing force that the valve clack pushed down is great, and the opening force of opening on is less, thereby leads to the operation unstability. In order to solve the problem, the space that the valve clack is cut apart with the intercommunication valve clack has set up balanced pore passage on the valve clack, make partial medium can flow through balanced pore passage, balanced the medium power, the power of opening and shutting of valve clack has been reduced, but because the existence of balanced pore passage, make the medium can flow by balanced pore passage, when not needing balanced medium power, the condition that the medium still can reveal still exists, the loss of pressure has been caused, simultaneously in the moment that the valve opened and shut, the velocity of flow transient increase, the impact that causes sealed face is very big, it is impaired to erode very seriously to lead to the case, short service life, cause the valve to leak outward easily.
