Flange type electric ball valve is a new type of pipe connector, which is characterized by a new product developed on the basis of compensation joint. Flange type electric ball valve is a device for connecting pipes, which is composed of body, sealing ring and compression member.
It is mainly used to absorb displacement, but cannot bear pressure and thrust. Working principle: after the expansion joint is installed on the pipe, tighten the elastic sealing ring of the nut. Under the action of the nut gland, it relies on the mutual slope to compress the outer ring of the pipe for sealing and connection. When the temperature changes, the pipe can expand and contract freely in the middle of the joint. When the foundation sinks, the pipe can deflect, and ensure that the seal has no leakage, so as to play the purpose of automatic compensation. After the flange type electric ball valve is installed on the pipe, tighten the elastic sealing ring of the nut, slope each other under the action of the nut gland, and press the outer ring of the pipe to seal and link. When the temperature changes, the pipe can stretch freely in the middle of the street. When the foundation sinks, the pipe can deflect, and ensure that the seal is free of leakage, so as to play the purpose of automatic compensation.
