Q:Principle of forced sealing ball valve
With spring to achieve forced sealing, not applicable to high pressure
Q:Role of ball valve DN20-Q11F-16
Q11F ball valve is to control the circulation and cut-off of the pipeline medium.
Q:What are the differences between the lever ball valve and the handwheel ball valve? What are their differences?
Group pairs of valves, have not heard of a lever type ball valve, only lever type safety valve, hand wheel type is only the way it drives different, the way is also ever-changing, to see the needs of individuals
Q:What does telescopic ball valve mean? What does it mean?
An expansion valve is mostly for repair or replacement of the water meter behind the expansion is the activity space, for example for water when the water meter is just let it back so easily won, for good and put it out to tighten the gentry good handle table.
Q:Pneumatic two stage ball valve principle
Two section type pneumatic ball valve, pneumatic piston two stage shut-off valve to achieve a two step or two step off the action of the cut-off valve is a special pneumatic valve, provides 0 degrees, 45 degrees, 90 degrees or 0 degrees, 90 degrees, three operating mode 180 degrees.
Q:What's the difference between a one piece ball valve and a two piece ball valve?
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
Q:What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?
From the above work principle can be seen: double acting pneumatic actuator, valve opening and valve closing all need compressed air thrust to perform. That is to say, the pneumatic actuator will remain in a position in case of loss of air.The single acting actuator belongs to the automatic reset type. After losing the continuous air pressure, the actuator will drive the valve back to the initial setting position under the tension of the spring.This answer is recommended by users
Q:Stainless steel ball valve Q41F-16P DN80 weight is
The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers
Q:Please professional help guide me
Valve handle rotation more times, it is likely to water seepage
Q:What are the advantages of an air operated ball valve in comparison with other types of valves?
Compared with other kinds of valves, pneumatic ball valve has angular travel, output torque, quick, stable and reliable opening, wide application and the following advantages.Antistatic function: a spring is arranged between the ball body, the valve stem and the valve body, so that the static electricity generated by the switching process can be exported.Long service life: because PTFE and other materials have good self lubrication, and friction loss of the ball is small, so pneumatic ball valve.Fluid resistance is small: pneumatic ball valve is the classification of all types of liquid resistance is the smallest, even if the diameter of pneumatic ball valve, its fluid resistance is quite small.Stem seal is reliable: it has two sealing surface, and the ball valve sealing surface materials widely used, all kinds of plastic, good sealing, can achieve full seal. It is also widely used in vacuum system. Because the stem only for imitation rotation transported without movement, stem packing seal is not easy to damage, and sealing ability increased with the increase of the pressure medium.Valve seat sealing performance: the use of PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and pneumatic ball valve sealing capacity as the medium pressure increases.
