Do You Know What Is The Butterfly Valve?

 Butterfly valve, also known as flap valve, is a simple structure of the control valve. Butterfly valve, which can be used for low-pressure pipeline media control switch means the closure (valve flap or disc) as a disc, rotating around the valve shaft to open and close a valve that can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, slurries, oils, liquid metals, and radioactive media. In the pipeline, it mainly cut off and throttling effect. 

Butterfly valve opening and closing pieces is a disc-shaped disc, the valve body around its own axis of rotation so as to achieve the purpose of opening and closing or regulation. Flanged double eccentric butterfly valve is a best example. Butterfly valve model is usually expressed as the type of butterfly valve, butterfly valve drive, butterfly valve connection, butterfly valve structure, butterfly valve sealing surface material or lining material, butterfly valve nominal pressure, butterfly valve body material. 

Precautions of Electric ball valve

Electric valves include ball valve,Butterfly Valve.When using the Electric ball valve, we should pay attention to something,the following i will introduce the Precautions of Electric ball valve.

1, in the case of high pressure, high temperature, high temperature and pressure materials should be used as electric ball valve material, such as: stainless steel, alloy, these material can withstand high pressure, high temperature.

2, for low temperature and low pressure, the material does not need too much adjustment.
3, electric valve parts need to be replaced to reduce the damage to the spool, but also conducive to the flow of media to avoid coking.
4, in the case of open electric ball valve, you can install some anti-vibration mechanism to prevent the internal structure of the electric valve to open the damage

What is the Electric butterfly valve

Electric butterfly valve refers to the closing piece (valve) moves along the centerline of the valve. There also have Electric Ball Valve.Depending on the type of movement of the valve disc, the change in valve seat opening is in direct proportion to the valve disc stroke.

Different from Cast Iron Check Valve Electric butterfly valve closing principle is to rely on the valve stem pressure, so that the sealing surface of the valve flap and valve seat sealing surface close fit, to prevent the flow of media. China's valves, "three to" have provided that the flow of electric butterfly valve, all from top to bottom, so it will be directional when installation.

About the Electric Ball Valve

Electric Cast Steel Ball Valve mainly by the electric actuator and ball valve, ball valve body, rotating 90 degrees role. Electric ball valve can not only cut off the media, or flow control system of choice.

Electric Floating Ball Valve mainly by the electric actuator to adjust the current to operate the ball valve. Standard signal electric actuator input and output signals for the 4-20mA and 220VAC power supply, the motor drives the worm gear set angle torque, control the valve to open and close the flow of medium distribution, and change or adjust the degree of rotation of the proportional valve
The following i will share knowledge about the Electric Butterfly Valve.Welcome to follow me and hope to get your supplement

Structure of Check valve

 Valves are various,Gate Valves. At here , i will share some knowledge about Check valve: According to the structure, can be divided into lifting check valve, swing check valve and butterfly check valve three. Lift check valve can be divided into vertical and straight-through two. Swing check valve is divided into single-valve, double-valve and multi-valve three. Butterfly check valve double Butterfly valve, butterfly single flap, the above types of check valve in the connection form can be divided into thread connection, flange connection, welding and clip-on connection of four
