A fast-response vacuum controller
ActiveCN224283631Ueasy to observeeasy to operateOperating means/releasing devices for valvesSlide valveClassical mechanicsControl theory
This utility model belongs to the technical field of vacuum control equipment, and in particular to a fast-response vacuum controller, including a vacuum controller housing, a vacuum controller body, a control panel, and a valve body mechanism. The vacuum controller body is disposed within the vacuum controller housing. A damping shaft is rotatably mounted on the control panel, and a strip block is radially fixedly mounted on the damping shaft. A storage groove is provided on the top side of the vacuum controller housing, and the strip block is mounted on the inner walls of the front and rear sides of the storage groove via damping hinges. The valve body mechanism is disposed within the vacuum controller housing and connected to the vacuum controller body. The valve body mechanism includes a mounting box, a U-shaped plate, two partitions, a guide and reset assembly, a transmission assembly, an electromagnet, and a magnetically made moving plate. This utility model has a reasonable design, can quickly respond to operation commands, improve execution efficiency, and optimize the operation interface to enhance ease of use and storage.

An electronic expansion valve
PendingCN122083547AReliable and controllable smoothnessAssembly accuracy is lowEfficient regulation technologiesLift valveElectronic expansion valveValve seat
This invention relates to an electronic expansion valve, comprising a drive assembly, a screw, a valve needle, a valve seat, a bearing, and a valve needle spring. The valve seat has a fluid passage. The drive assembly drives the screw to rotate and move axially. The valve needle has an axial mounting hole inside, and its upper part has a bearing cavity to accommodate the bearing. The lower end of the screw extends into the axial mounting hole and is rotatably connected to the bearing, allowing for axial sliding. A screw retaining ring is provided at its lower end, and a screw annular protrusion is provided on its outer periphery. The valve needle spring is sleeved on the screw and confined between the screw annular protrusion and the upper end face of the valve needle. Downward movement of the screw compresses the valve needle spring through the screw annular protrusion, pushing the valve needle downward. Upward movement of the screw pushes the valve needle upward through the screw retaining ring against the bearing, thereby achieving stable axial movement of the valve needle to precisely control the opening and closing of the fluid passage. This structure achieves pure axial transmission through the bearing, effectively preventing the valve needle from rotating and vibrating with the screw. The compact layout of the valve needle spring significantly shortens the axial dimension of the valve body, improving transmission reliability and service life.
