Whether the pneumatic butterfly valve can be installed on the vertical pipeline [Working principle] The butterfly valve is a valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid passage. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0, and the joint screw adjusted at both ends can make the standard product have ± Adjustable range of 4°.
Summary of valve selection Through the above analysis, it can be known that in general, the gate valve should be the first.
For more than ten years, we have been obsessed with the research and development and exploration of control valves and drive actuators. We have carefully crafted and improved our products with the ultimate attitude. We have achieved a unique brand of ZBSF series steam solenoid valves. Shanghai Juliang Solenoid Valve Manufacturing Co., Ltd. The company develops a product for applications in medical equipment, drying equipment, cleaning equipment, vacuum equipment, electroplating coating, distillation machine, oil filter, humidifier, food machinery, petrochemical industry and other industries.
According to the situation of use, butterfly valves are generally divided into several types, namely pneumatic butterfly valves, electric butterfly valves and manual butterfly valves. These three types of butterfly valves are currently widely used and applied in the industry. These three butterfly valves include a variety of butterfly valve types. In the market, regardless of their sales and competition, they are all showing an increasing situation. The butterfly valve is relatively simple in structure. The development advances broadly. In recent years, the continuous development and improvement of technology has gradually developed it into an indispensable part of the valve.
It cannot be assembled into an electric valve.
Whether pneumatic butterfly valves can be installed on vertical pipelines. Classification: Electric ball valve types include: floating ball valve, fixed ball valve, orbital ball valve, V-shaped ball valve, three-way ball valve, stainless steel ball valve, forged steel ball valve, ash unloading ball valve, sulfur-resistant ball valve, Three-way ball valve, pneumatic ball valve, electric ball valve, ferrule ball valve, welded ball valve, flange ball valve, threaded ball valve.
The ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid adjustment and control. Among them, the hard-sealed V-shaped ball valve has a strong gap between the V-shaped core and the metal seat of the hard alloy. Shearing force is especially suitable for media containing fibers and tiny solid particles.
Pneumatic V-shaped regulating ball valve Pneumatic V-shaped ball valve is a control valve with a right-angle rotation structure. It is composed of a piston type double-acting or single-acting (spring return type) pneumatic actuator and a V-shaped valve structure. It is matched with an electric valve positioner. It can be used to realize proportional adjustment; it can be used with solenoid valve and control box to realize two-position cut-off control.
