Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to achieve opening and closing. It is mainly used as a cut-off valve. It can also be designed to have the function of adjustment or segment valve. The use of medium-diameter pipes is increasing. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard sealing pneumatic butterfly valve, soft sealing pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of the pneumatic butterfly valve are simple structure, small size, light weight and low cost. This feature of the pneumatic butterfly valve is particularly remarkable. It is installed in a dark tunnel at high altitude and is controlled by a two-position five-way solenoid valve. It is easy to operate and can also adjust the flow medium.g failure or airway obstruction that cannot breathe normally. The home ventilator is actually equivalent to an air compressor. When the patient’s lungs fail or the airway is blocked, the home ventilator can continuously blow pressurized air to the patient’s airway to keep the airway open and maintain Breathe normally. Usually patients with sleep apnea syndrome (snoring and pause) and patients with severe emphysema, pulmonary heart disease, chronic obstructive pulmonary disease or type II respiratory failure with high carbon dioxide need to buy a home ventilator. In this way, it does not need to be used in the hospital, saving a large part of the cost and time.
