What should be paid attention to when the electric ball valve is connected to the pipeline? After the electric ball valve is installed on the pipe, the elastic sealing ring of the nut shall be tightened, and under the action of the nut gland, it shall be sealed and connected by pressing on the outer ring of the pipe with mutual inclination. 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. When the electric ball valve connects the drainage vent pipe with the air duct or the flue, due to the different gas pressure in the vent pipe, air duct and flue, the gas will flow into the vent pipe when the gas in the air duct or flue is large, which will hinder the rise of the odor in the vent pipe and damage the balance of the drainage system connected by the electric ball valve; When the air pressure in the air duct or flue is low, the air extraction in the air duct will also flow into the air duct or flue. If it enters the room, it will pollute the indoor air and affect the air quality.
Therefore, the vent pipe connected by the electric ball valve should be 300 mm higher than the roof; In places with doors and windows around, in order to avoid odor affecting the environmental quality of human activity space, the installation of vent pipe should be 600 mm higher than the top of the door and window or led to the side without doors and windows; On the flat roof where people often stay, the vent pipe should be 2 meters higher than the roof, and lightning protection devices should be installed according to the actual situation.
