    • Disclosed herein is a flow path switch control device used in a control system such as HVAC, refrigeration system and the like. In the prior art, since the pressure at an upper portion of a piston will drop instantaneously at the moment when a pilot valve is opened and closed, a large pressure difference is formed between the upper and lower sides of a piston to drive the piston to move, which results in a strong impact between a piston stopping member and the piston. Therefore, the life span of a product and the operating stability of the system will be affected. The flow path switch control device of the present invention includes a fluid inlet, a fluid outlet, a valve device arranged between the fluid inlet and the fluid outlet, and a pressure balancing control circuit. An adjusting device is provided in the pressure balancing control circuit to reduce a pressure change in fluid passing through the pressure balancing control circuit when the flow path switch control device is opened/closed, which enables the flow path switch control device to be smooth during the process of opening or closing, and thus avoid the problem of strong vibration and noise occurred at the moment when the solenoid switch is operated under large pressure difference.
    • 这里公开了一种在诸如HVAC,制冷系统等的控制系统中使用的流路开关控制装置。 在现有技术中,由于活塞上部的压力在先导阀打开和关闭的时刻立即下降,所以在活塞的上侧和下侧之间形成较大的压力差以驱动活塞 移动,这导致活塞止动构件和活塞之间的强烈冲击。 因此,产品的使用寿命和系统的运行稳定性将受到影响。 本发明的流路开关控制装置包括流体入口,流体出口,布置在流体入口和流体出口之间的阀装置以及压力平衡控制电路。 在压力平衡控制电路中设置有调节装置,当流路切换控制装置打开/关闭时,减小通过压力平衡控制电路的流体的压力变化,这使得流路切换控制装置在 打开或关闭的过程,从而避免了当电磁开关在大的压力差下操作时发生强烈的振动和噪音的问题。
