摘要： A quarter-turn pin valve actuator has a housing and a rotatable core configured to rotate about a central axis inside the housing. The rotatable core has a two bearings mounted to roll in a circular path about the central axis. The actuator comprises a two-position ramped roller plate that is displaced axially when the bearings are rolled a quarter turn. The actuator includes a push plate and a spring disposed between the push plate and the ramped roller plate. The push plate has a central socket for receiving a pin of a pin valve to which the actuator is connected. When the rotatable core is rotated, the bearings exert a force via the ramped roller plate on the push plate which in turn displaces a pin of a pin valve to which the actuator is connected.

摘要： A heat-transferring fin is attached to an electric cable or to a packaged double cable of an electric radiant heating system. The fins can be attached using twist clips. Each twist clip includes an upper gripping member, a lower gripping member connected to the upper member by an upright support member, and a handle portion looping downwardly from the lower gripping member to enable a user to hold the clip and to manually twist the clip to cause the upper and lower gripping members to rotate relative to the fin and cable such that the fin and cable are clipped together. This twist clip enables quick and easy attachment of fins to cables, which greatly reduces the time and effort required to install an electric radiant heating system. This technology can be used in electric radiant floor heating or electric radiant wall heating.
摘要翻译：传热翅片连接到电缆或电辐射加热系统的封装双电缆。翅片可以使用扭曲夹固定。每个扭曲夹具包括上夹持构件，通过直立支撑构件连接到上构件的下夹持构件和从下夹持构件向下环绕的手柄部分，以使使用者能够夹持夹子并手动地将夹子扭转到导致上和下夹持构件相对于翅片和电缆旋转，使得翅片和电缆被夹在一起。该扭扣可以快速方便地将散热片连接到电缆上，这大大减少了安装电子辐射加热系统所需的时间和精力。该技术可用于电辐射地板采暖或电辐射墙加热。
