    摘要: The water hammer effect mitigation controlling device of solenoid valve for fluid of the present invention includes a controller and a solenoid valve. The controller generates and transmits a control signal to the solenoid valve when receiving a closing command. The control signal includes alternatively arranged multiple closing and open signal intervals. The time duration of the closing signal interval is shorter than the closing reaction time of the solenoid valve, the closing distance of the valve body during each closing signal interval is larger than an opening distance during each open signal interval, and the valve body is switched to a closed state during the control signal. The opened-closed switching time is prolonged by multiple closing and open signal intervals, and the water hammer effect caused by suddenly closing the valve body is reduced with no extra hardware, giving the present invention the advantage of lowered cost.

    摘要: Disclosed are a sterile connection member and a sterile connection apparatus. The sterile connection member includes a main body. A first surface of the main body is connected to an external pipeline. A fluid channel is arranged inside the main body. The fluid channel penetrates from the first surface to a second surface of the main body. The second surface includes at least one first hook and/or at least one second hook. The first hook is matched with a second hook of the main body of another sterile connection member to form a buckle connection, and/or the second hook is matched with a first hook of the main body of another sterile connection member to form a buckle connection. The sterile connection member further includes an unlocking hole formed in the main body and communicating with the buckle connection.

    摘要: A clamping device for fluidically and mechanically connecting two hose barbs. The clamping device includes a seal and a locking mechanism, wherein the locking mechanism can be transferred from a mounting condition to an assembled condition. In the mounting condition, the hose barbs can be inserted into the clamping device, while in the assembled condition, those hose barbs are locked in place in a position in which free ends of the hose barbs face each other and a seal coaxially aligns and fluid-tightly connects the free ends.

    摘要: A rotary joint capable of measuring a rotation angle with high accuracy is provided. The rotary joint includes: a flange; a rotor whose one end is connected with the flange and that has a tubular shape; a shaft whose outer periphery is connected with an inner periphery of the rotor so that the shaft is rotatable about a central axis of the rotor as a rotation axis; and a rod whose one end is connected with the flange and that is provided in an opening so as to extend from one end side of the shaft along the central axis; an angle measurement unit that is connected with the opening so as to extend from another end side of the shaft to another end of the rod and that measures a rotation angle between the rod and the shaft with the central axis serving as the rotation axis; and a shield member that is formed in a cup shape, an outer periphery of the shield member being connected with the opening so that the shield member is rotatable along the central axis, the other end of the rod being connected with an inner periphery of the shield member, and the shield member acting as a shield between the rod and the angle measurement unit in the opening.

    摘要: A tube-attached coupling structure is provided by using a piping coupling with good compatibility, workability and processability. A manufacturing method of the tube-attached coupling structure includes a step of preparing a photocurable gel-like body in a hollow cylindrical shape, a step of fitting the photocurable gel-like body in the attaching hole, a step of inserting an end portion of a connection tube into a hollow hole of the photocurable gel-like body, and a step of curing the photocurable gel-like body by irradiating the photocurable gel-like body with light.
