进口缓闭止回阀美国阿卡迪亚品牌

进口缓闭止回阀Product description:

It includes the valve body, valve clack, cavity, guide rod, piston and valve cover. A cavity is installed at the top of the valve body, a valve clack is installed at the top of the cavity, a guide rod is connected below the valve clack, a piston is installed at the end of the guide rod, the valve clack is connected with the piston through the guide rod, and a valve cover is installed at the end of the valve body. The beneficial effect is that when the outer circle of the piston matches the internal diameter of the cavity, damping effect will occur, and the valve clack will slow down, The purpose of slow closing is achieved until the valve clack contacts with the valve seat, and the medium is closed to play a check role. The reliability and tightness of the contact between the valve clack and the valve seat sealing pair are enhanced, and the impact force between the valve clack and the valve seat sealing pair is reduced, which can improve the service life of the valve.

进口缓闭止回阀characteristic:

The closing and opening actions are realized under the medium pressure. During the opening process, the medium pressure acts under the valve clack, pushing the valve clack to open. During the opening process of the valve clack, the medium pressure will enter under the piston through several guide holes at the lower part of the cavity, and then continue to push the piston, which is helpful for the rapid opening of the valve clack. In the initial stage of closing, under the effect of medium pressure, the piston drives the valve disc to move down rapidly through the guide rod. When the piston outer circle matches the inner diameter of the cavity, damping effect will be generated. At this time, the valve disc will slow down to achieve the purpose of slow closing until the valve disc contacts the valve seat, closing the medium, playing a check role, and the reliability and sealing of the contact between the valve disc and the sealing pair of the valve seat will be strengthened, The service life of the valve can be increased by reducing the impact force between the valve disc and the valve seat sealing pair.

进口缓闭止回阀Principle:

The guide rod is connected with the valve clack and the piston to form a component, which can move up and down repeatedly to realize the closing and opening action under the medium pressure. During the opening process, the medium pressure acts under the valve clack, pushing the valve clack to open. During the opening process of the valve clack, the medium pressure will enter under the piston through several guide holes at the lower part of the chamber, and then continue to push the piston, which is helpful for the rapid opening of the valve clack. In the initial stage of closing, under the effect of medium pressure, the piston drives the valve disc to move down rapidly through the guide rod. When the piston outer circle matches the inner diameter of the cavity, damping effect will be generated. At this time, the valve disc will slow down to achieve the purpose of slow closing until the valve disc contacts the valve seat, closing the medium, and playing a check role. The design advantage of this structure is that:, The reliability and tightness of the contact between the valve disc and the sealing pair of the valve seat are enhanced, and the impact force between the valve disc and the sealing pair of the valve seat is reduced, which can improve the service life of the valve.(仅供参考)
