Q:One piece ball valve, two piece ball valve, three piece ball valve, respectively, under what circumstances?
A piece of ball valve, the current market pressure of most products below 6.4MPA, two piece ball valve about 12.8MPA products are also common, there are 20MPA, three pieces of ball valves are mostly below 6.4MPA. Know the characteristics and shortcomings of these three kinds of ball valves, you can completely choose according to your own needs.
Q:One stainless steel ball, two pieces, three pieces of difference, use
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 is the difference between PPR ball valve and PPR live ball valve?
PPR and PPR union ball valve is different: PPR union ball valves and pipes on both sides (hot melt) connected between, a movable joint (hot melt) and (link with) nut, maintenance, convenient disassembly and replacement of the valve, the union not only cut off the PPR ball, maintenance.
Q:How to distinguish three points copper ball valve, two points copper ball valve
Three points, two points mean the specifications of the ball valve, three refers to the diameter of 32, two refers to the diameter of 25
Q:Allowable leakage on ball valves: what does CLassVI mean?
This is the valve leakage level, level VIThe GB/T4213-92 standard specifies six grades for the valve leakage. The specific requirements are shown in the standard table. The lowest level is level I, without specific requirements; the highest level is grade VI, i.e., the bubble grade.
Q:What does "q341" and "q347" mean?
Q341 is a turbine driven flange straight through floating ball valveQ347 is a turbine drive flange through fixed ball valveShintex valve0577Eight thousand six hundred and ninety-oneSeven thousand five hundred and sixteen
Q:Is the water inlet valve good or the ball valve well?
Good with the gate valve, the ball valve requires more space than the gate valve.
Q:Are ball valves and float valves a thing?
It's not the same. Ball valve is one of the pipes used.Float valves belong to the class of liquid level measurement and control.
Q:What are the differences and advantages between O ball valve and V ball valve?
5, high reliability1, the ball and valve seat a pair of sealing pairs, there will be no abrasions, rapid friction and other failures;2, stem into the built-in type, to eliminate the stem under the action of fluid pressure may be caused by the packing gland release flying accident hidden trouble;3 、 adopt antistatic and fireproof structure ball valve, which can be used to transport petroleum, natural gas and gas pipelinesV type ball valve structure of a right angle turn, can achieve flow regulation, according to the V type angle V type sphere, realize different proportions, V type ball valve and valve actuator and positioner supporting the use, the ratio can be adjusted V type valve adjustment for a variety of occasions, with a rated flow coefficient large, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. For control of gas, steam and liquid medium.V type ball valve for rotary type rectangular structure by V type valve, pneumatic actuator, positioner and other accessories; there is a similar more than 100 of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors, the shear capacity of strong.
Q:What is the nominal pressure 1.6p of a ball valve?
Nominal pressure: reference value relating to the pressure resistance of a piping system. For ease of use, usually the priority of the R10 series is taken. Nominal pressure refers to the pipe in the two temperature (20 degrees Celsius) when the water delivery pressure. If the water temperature is between 25 and -45 degrees, the coefficient of temperature drop should be adjusted to correct the working pressure.
