(1) Truncation class: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve, etc.
Truncated class valve is also called closed circuit valve, stop valve, its role is to put through or truncate the medium in the pipeline.
Check valve, also known as check valve or check valve, check valve belongs to an automatic valve, its role is to prevent the pipeline medium backflow, prevent the pump and drive motor reverse, and the leakage of the container medium. The bottom valve of the water pump is also a check valve.
Explosion-proof valve, accident valve, etc., the role of safety valve is to prevent the pipeline or device in the medium pressure exceeds the specified value, so as to achieve the purpose of safety protection.

By structural characteristics
The structural characteristics of the valve can be divided into: according to the direction of movement of the closing member relative to the seat:
(1) closure door shape: the closing piece moves along the center of the seat; Such as stop valve
(2) Cock and ball: the closing piece is a plunger or ball, revolving around its center line; Such as plug valve, ball valve
(3) Gate shape: the closing parts move along the center of the vertical seat; Such as gate valve, gate, etc
(4) Swing shape: the closing part rotates around the axis outside the seat; Such as swing check valve, etc

The following are several stainless steel valve material parameters and specific application
(1) Angle stroke including ball valve, butterfly valve, plug valve and other categories
(2) straight travel including gate valve, globe valve, Angle seat valve, etc.
This classification method is divided by principle, function and structure, and is the most commonly used classification method at home and abroad. Generally, there are gate valves, globe valves, throttle valves, instrument valves, plunger valves, diaphragm valves, plug valves, ball valves, butterfly valves, check valves, pressure relief valves, traps, regulating valves, bottom valves, filters, blowdown valves, etc.
Because the use of the valve is wide, so it plays a great role. In power plants, for example, valves control the operation of boilers and steam turbines. In petroleum and chemical production, valves also play a role in controlling the normal operation of all production equipment and technological processes. The same is true in other sectors. Despite this, valves are often overlooked compared to other products. For example, when installing machinery and equipment, people tend to focus on the main machinery and equipment, but neglect the valve. This will reduce the overall production efficiency or stop production, or cause a variety of other accidents. Therefore, the selection, installation, use of valves must be responsible work.
Electric drive valve is commonly used to drive the valve, usually called the driving device in the form of this driving device for the valve electric device, valve electric device has the following characteristics: 1) fast opening and closing, can ** shorten the time required to open and close the valve; 2) Can reduce the labor intensity of the operator, especially suitable for high pressure, large diameter valves; 3) Suitable for installation in manual operation or difficult to access the position, easy to achieve remote control, and the installation height is not restricted; 4) Conducive to the automation of the whole system; 5) Power sources are easier to obtain than air and liquid sources, and their wiring is much simpler to lay and maintain than compressed air and hydraulic lines.
The disadvantage of valve electric device is that the structure is complex, and it is more difficult to use in wet places. When used in explosive medium, flameproof measures need to be adopted.
Valve electric device according to the different types of driven valves, can be divided into Z type and Q type two categories. The output shaft of the Z valve electric device can be turned many times, which is suitable for driving gate valve, globe valve, diaphragm valve, etc. The output shaft of the electric device can only rotate 90¡ã. It is suitable for driving plug, ball and butterfly valves. According to its protection type, there are ordinary type, flameproof type (to B), heat resistant type (to R) and three in one type (outdoor, anti-corrosion, flameproof, to S).
The valve electric device is generally composed of a transmission mechanism (reducer), a motor, a stroke control mechanism, a torque limiting mechanism, a manual-electric switching mechanism, and an opening indicator.
Pneumatic and hydraulic valves
Pneumatic valve and hydraulic is a certain pressure of air, water or oil as the power source, the use of cylinder (or hydraulic cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, hydraulic pressure or hydraulic pressure is 2.5MPa~25MPa. If used to drive diaphragm valves; Pneumatic and hydraulic actuators are used to drive ball, butterfly or plug valves. Hydraulic device driving force is large, suitable for driving large diameter valves. If used to drive the plug valve, ball valve and butterfly valve, the reciprocating movement of the piston must be rotated. In addition to the use of cylinder or hydraulic cylinder piston to drive, and the use of pneumatic film driven, because of its stroke and driving force is small, it is mainly used for regulating valves.
Hand operated valve
Manual valves are the most basic way to drive valves. It includes two kinds of direct drive by hand wheel, handle or plate hand and drive by transmission mechanism. When the opening moment of the valve is large, it can be driven by the gear or worm gear drive to achieve the purpose of omission. Gear drive is divided into straight gear drive and cone gear drive. Gear drive reduction ratio is small, suitable for gate and globe valves, worm drive reduction is larger, suitable for plug flash, ball and butterfly valves.
