The utility model relates to moxa -burning technical field. A kind of multi-position combined moxa -burning moxa -burning chair, including a seat base, seat base includes seat plate and chair back, chair back includes a rear end opening hollow fixed back plate and the movable back plate for closing the rear end opening of hollow fixed back plate, movable back plate and hollow fixed back plate longitudinal sliding connection;At least three first installation holes from top to bottom are set in hollow fixed back plate, and first installation hole is equipped with first partition moxa -burning device;The seat plate is slidably connected with an abdominal moxa -burning plate in front-rear direction, and the abdominal moxa -burning plate includes sequentially connected push-pull plate and moxa -burning support plate, and at least three second installation holes from top to bottom are set in moxa -burning support plate, and second installation hole is equipped with second partition moxa -burning device.The utility model has realized the problem that clinical moxa -burning operation cannot simultaneously consider back and abdomen due to body position restriction.

This invention belongs to the technical field of hydraulic component testing and discloses a deep-sea steady-state performance testing system and method for electromagnetic directional valves. The testing system includes a pressure cylinder, an electromagnetic directional valve, a pressure compensation unit, and a testing unit. The electromagnetic directional valve is housed in the pressure cylinder, which provides simulated pressure at full ocean depth. The pressure compensation unit is connected to the electromagnetic directional valve to compensate for the full-ocean-depth pressure, thus enabling the electromagnetic directional valve to operate at its rated voltage. The testing unit is connected to the electromagnetic directional valve to test the performance of its inlet and outlet ends. The testing unit includes a throttle valve connected to the outlet end of the electromagnetic directional valve to simulate its load. This invention also discloses a testing method for the above-mentioned testing system. This invention solves the problem of the inability to perform full-ocean-depth steady-state performance testing of electromagnetic directional valves.
