Abstract

The invention provides a vacuum chamber negative pressure adjusting device and a method for using the same. The vacuum chamber negative pressure adjusting device comprises a valve, a tapered plug, a spring and a sealing slide rod, wherein the tapered plug is arranged in an inner cavity of the valve, and the sealing slide rod is movably connected to the lower end of the valve. The top of the innercavity of the valve is matched with a tapered face of the tapered plug, a hole slot running through the top of the inner cavity of the valve is arranged at the upper end of the valve, a through hole communicated with the inner cavity of the valve is arranged at the lower end of the valve, one end of the sealing slide rod penetrates through the through hole, enters the inner cavity of the valve and is connected with the tapered plug through the spring, a communicated channel is formed among the through hole, the inner cavity and the hole slot, and the sealing slide rod vertically moves in the inner cavity of the valve so that gas flows in the channel. The vacuum chamber negative pressure adjusting device is reliable in structural sealing and simple and easy in machining, is mounted on a vacuum chamber to be used, can reach negative pressure needed by the vacuum chamber by pushing and pulling the sealing slide rod to move in the inner cavity of the valve according to the requirement of the vacuum chamber on negative pressure, and can meet the technical requirements for stable soaking liquid level in the vacuum chamber, adjustable soaking liquid level, explosion prevention and the like.

Description

technical field [0001] The invention relates to the field of vacuum technology, in particular to a vacuum chamber negative pressure regulating device and a using method thereof. Background technique [0002] The prepreg used in the field of copper clad laminates is made of reinforcing materials impregnated with glue. In order to obtain prepregs with better wetting effect, the method used includes vacuum impregnation technology, which is to impregnate the reinforcing materials with the impregnating liquid in a vacuum chamber. , this kind of vacuum impregnation technology can effectively enhance the bonding effect of materials and impregnating liquid, but in order to obtain the ideal bonding effect, it must meet the technical requirements such as stable impregnating liquid level, adjustable impregnating liquid level, explosion-proof, and the current vacuum chamber Most of them are connected to a vacuum pump through a pipeline, and the vacuum pump is used for vacuuming, and the...
