4results about How to "Achieve power saving effect" patented technology

A melting device for gel chromatography, belonging to the field of auxiliary technology for detection mechanisms, includes a crucible, a sealed cylinder, a sealed cap, an electric push rod, an electric heating mechanism, a base plate, and a vibration motor. The crucible, sealed cylinder, sealed cap, electric push rod, electric heating mechanism, base plate, and vibration motor are assembled together. An isolation plate with a shaft hole is fixedly installed in the middle of the sealed cylinder, dividing the upper and lower ends of the sealed cylinder into a heating chamber and an equipment chamber. Under the combined action of these mechanisms, the analyte in the crucible can be sealed and heated through the sealed cap, thus improving heating efficiency and achieving energy savings. The vibration energy generated by the vibration motor causes synchronous vibration of the analyte in the crucible, ensuring uniform heating of the solid analyte and reducing the probability of excessive heat-induced denaturation of the analyte at the lower end of the crucible, thereby maximizing the accuracy of the detection data of the analyte in the gel chromatography. In summary, this invention has good application prospects.

The utility model provides a kind of double valve plug gas solenoid valve with pressure relief valve, the solenoid valve's electromagnetic coil group energization can make one fixed core produce magnetic force, and two-stage drive first, second movable core and main, auxiliary valve plug open valve. Among them, a pressure relief valve group is equipped between the first movable core and the second movable core, the pressure relief valve group is communicated between the air inlet chamber of air inlet end and the valve port portion of air outlet end, when electromagnetic coil group is magnetized, first drive second movable core to move and make pressure relief valve group open, let the gas in air inlet chamber from valve port portion small flow release, by this can open main valve plug after relieving the static pressure of gas in air inlet chamber, overcome the problem that known double valve plug solenoid valve must use larger power drive because of static pressure and cause main valve plug to open difficult, achieve the effect of power saving and prevent valve plug stick and open valve abnormal.
