The utility model provides a kind of valve group and compressor of miniaturization reciprocating compressor, it is related to compressor field, to the problem that the temperature of existing small compressor cylinder head is too high, gas flow resistance increases and leads to efficiency reduction, by the offset structure of valve plate on the valve plate subassembly suction hole, enlarge suction valve port flow area, reduce suction resistance, reduce the pressure loss and friction heat in suction process, to reduce suction overheating, from the source to relieve cylinder head overheating problem, allow to adopt smaller size cylinder hole, meet the demand of compressor miniaturization, the valve tongue both sides of suction valve piece are provided with contraction part to form waist, exhaust hole is arranged between two sides waist, adapt to the compact space of miniaturization valve group, suction muffler outlet and cylinder cover keep apart, leave gap, cut off the heat conduction path between cylinder cover and suction muffler, form heat insulation, reduce suction overheating, reduce cylinder head temperature benign cycle, improve miniaturization reciprocating compressor efficiency.

This utility model provides a vibration structure for a spherical graphite vibratory grinding device, belonging to the technical field of spherical graphite vibratory grinding devices. The vibration structure includes: a vibratory body, a vibration excitation device, a support base, a transmission shaft, an adjustment mechanism, and a sealing cover. The vibratory body is cylindrical, with a spherical grinding cavity inside, the inner wall of which is made of stainless steel. The support base is fixedly mounted on the ground, and its upper surface is connected to the bottom of the vibratory body via a shock-absorbing spring assembly. The vibration excitation device includes an eccentric wheel and a drive motor, which is fixedly mounted on the side wall of the support base. The output shaft of the drive motor is connected to the transmission shaft via a coupling. This invention solves the technical problems of uneven grinding, poor vibration control accuracy, and insufficient equipment stability in existing spherical graphite grinding devices.

The invention discloses a drinking water preparing and filtering device and method based on a magnetized filter element, and relates to the technical field of filtering. A filter cartridge; a first filter plate, a second filter plate, a third filter plate and a fourth filter plate; the telescopic unit is arranged on the connecting base and used for driving the first filter plate, the second filter plate and the third filter plate to move in the direction away from the fourth filter plate, so that the shaftless spiral piece is in an elastic extension state. According to the invention, when foreign matters and impurities are cleaned, a telescopic unit drives a first filter plate, a second filter plate and a third filter plate to move in a direction far away from a fourth filter plate, so that a shaftless spiral sheet is elastically stretched and deformed, and gaps between activated carbon particles and magnetized particles are increased; foreign matters and impurities can flow out to the water outlet through gaps between the activated carbon particles and the magnetized particles, so that the foreign matters and impurities are removed, the replacement period of the filter element is prolonged, and the replacement frequency of the filter element is reduced.
