Q:Butterfly valve and ball how to distinguish from the appearance

See the ball valve and butterfly valve is round are generally seen in the way some can not see

Q:And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?

When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body

Q:Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?

Q11F-10P 16P is the meaning of stainless steel internal thread ball valve. One is 10 kilograms, one is 16 kilogramsQ valve Code: ball valveManual no code representation1 connection: internal thread1 structure form: floating through typeF sealing material: fluoroplastic10 valve pressure: 10 kg 1.0MPa 16=1.6mpaP body material: stainless steel

Q:What's the difference between a copper ball valve and a stainless steel ball valve?

The difference between copper ball valve and stainless steel ball valve:1, they use the material is completely different, steel ball valve adopts copper, stainless steel ball valve is stainless steel.2, copper ball valve corrosion resistance is excellent, switch operation is smooth, labor-saving, durable without leakage. Stainless steel will not cause corrosion, pitting corrosion, corrosion or wear, and high temperature resistance. The average stainless steel is more expensive.3, according to the same pressure environment, the price is stainless steel cheaper, and copper ball valve medium temperature is much higher than the stainless steel ball valve, if the medium temperature is too high. Copper ball valve must be used! If the medium temperature is not more than 80 degrees. With stainless steel ball valve on it

Q:Is the two piece ball valve in the direction of the pressure pipe?

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:What does W represent in copper ball valve Q11W-16T?

Valve sealing materials are all valves of the body material, sealing surface material code with "W" said

Q:What's English for ball valves?

Mechanical introductionThe main characteristics of the electric ball valve of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integrated, or can be combination. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow medium. Ball valve is a new type of valve widely adopted in recent years. The resistance of fluid is small, and its resistance coefficient is equal to that of pipe of same length.The ball valve is simple in structure, small in size and light in weight. Tight and reliable, at present, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum systems have been widely used. Convenient operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. Easy maintenance, ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement are more convenient. In full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, will not cause the valve sealing surface erosion. Wide range of applications, from a few millimeters to a few millimeters, large to a few meters, from high vacuum, high pressure can be applied.It is generally believed that the ball valve is suitable for direct opening and closing, but the development of the ball valve has been designed to make it throttling and controlling the flow. The main features of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integrated, or can be combination.

Q:Must I use the ball valve for the heater?

Valve main points and angle valve, ball valve in the water pressure is large enough to use, angle valve can increase the pressure of a little water.

Q:How to distinguish between cold water valve and hot water ball valve?

By the way, do you only require the working medium of the valve, general cold water and hot water?;Can provide the next 1, the valve's general use temperature of 2, whether the media granular impuritiesBoiling hot water is only 100 degrees; general, general valve can reach this use conditions,So cold water and hot water can choose the same type of valveI think the valve you want to know is not the drinking water valve you use at school?

Q:What is a high handle ball valve? What's the difference between it and ordinary ball valve?

Long distance between the valve casing and valve ball valve operating handle, mainly used for pipeline insulation, thermal insulation when the body is exposed in the insulation material,
