The invention discloses a composite damping coating comprising a damping layer and a constraining layer. The damping layer is a solvent-free modified polyurethane damping coating, and the constraining layer is a solvent-free modified epoxy resin constraining coating. According to the composite coating provided by the invention, the constraining layer is used for reducing sound, and the damping layer is used for insulating sound, such that frequency from a sound source can be reduced, and muting and noise reduction purposes can be achieved. The coating provided by the invention has the characteristics of wide damping temperature range, high loss factor after being combined with a metal plate material, good damping effect, and the like. Also, the coating does not contain an organic solvent. The coating has the advantages of normal-temperature curing and convenient and fast construction. The coating is non-toxic and flame-retardant.

Conversion valve for static testing

Номер: CN104533861A
Автор: LI WEIBO, WU MINGSONG, FU HUAJUN, SUN ZHENHUI
Принадлежит:

The invention belongs to the hydraulic pressure field and relates to a conversion valve used for having conversion test for the oil path for servo valve static testing and mainly used for the hydraulic pressure system of the servo valve static testing table. The conversion valve comprises a left end cover, a left spring seat, a left spring, a left orifice, a left top, a valve core, a valve sleeve, a shell, a right orifice, a right tip, a right spring seat, a right end cover, a right spring, a top plug, an adjusting bolt and a locking nut; the valve sleeve is located in the shell. The switch of the oil is controlled for conveniently testing the flow, pressure and interior leakage characteristic of the servo valve; the structure is simple and the reliability is high. The uniform pressure groove is formed on the valve core for preventing the clamping stagnation of the valve core and guaranteeing the sensitive action for the valve core.
