- Q:What are the uses and characteristics of copper ball valves?
- Copper ball valve features:1, suitable for regular operation, quick and easy to open and close.2, fluid resistance is small.3, simple structure, relatively small size, light weight, easy maintenance.
- Q:Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no problem with the 10 Water Leakage.Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no Water Leakage problem, while the valve under the same position is fixed and can not rotate, will this situation is normal? Is it possible to leak water in the future?
- This nut should be tight and can not move. There is a rubber pad in it, so it is not leaking at all. It will leak for a long time. It is suggested that the wrench should be tightened clockwise (from top to bottom)
- Q:Butterfly valve and ball how to distinguish from the appearance
- To say the difference, the biggest difference is that the butterfly valve is a piece of open and close, and the ball is a ball. They work by spinning their own axes!(1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;(2) butterfly valve structure is relatively simple, low pressure general use butterfly valve, butterfly valve the maximum pressure can only reach 64 kilograms. Ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.(3) butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric three, the eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg;(4) the valve can also be divided into soft seal and seal, soft seal valve can reach the highest temperature below 280 degrees, the pressure is below 64 kilograms, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms.
- Q:How to distinguish three points copper ball valve, two points copper ball valve
- I. identification methods: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.Two, copper ball valve is a brief introduction:The ball valve is mainly used to cut off or connect the line of medium, can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.
- Q:Can the check valve replace the ball valve?
- Can not be replaced, because the ball valve to play a maintenance, cut off the role of water sources
- Q:The valve nominal 1/2, 3/4 is how much?
- The 1 point is DN25 mm1/2 is DN15 mm3/4 is DN20 mm
- Q:PE pipe size diameter 3/8, diameter 1/4, material: low density polyethylene, pressure 170psi;Valve material: copper, and PE pipe connection interface with lock nut.Is this connection reliable? Will the pipe break due to excessive compression? Are there any requirements for the size of the joint and the size of the nut?
- After the impact, for a period of time, PE pipe cracking phenomenon, this is what causes? This is connected to the tap water.Chasing the answerWhere is it cracked?!
- Q:What's the advantage of using an electric ball valve?
- Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.
- Q:I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......
- 2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.
- Q:Daily maintenance and common maintenance of ball valves, Q347F-16C and Q41F-16C
- Filler and sealing materials pay attention to point, basically no technical things
