- Q: How does ball valve indicate?
- Valve type designation method is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear Edition
- Q: Gate valve, ball valve, the difference between the pressure regulating valve
- Gate valve and stop valve are shut-off valve, is the most common two valves. From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious. Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions.
- Q: Maintenance of PPR pipe ball valve is live or hot melt?
- CharacteristicFirst, wear-resisting; because the hard sealing ball valve spool is alloy steel spray welding, sealing ring is alloy steel surfacing, so hard sealing ball valve in the switch will not cause too much wear and tear. (its coefficient of hardness is 65-70)Two, good sealing performance; because the hard sealing ball valve sealing is artificial grinding, until the valve core and the sealing ring completely in conformity with the use. So his sealing performance is reliable.Three, switch light; because the hard sealing ball valve sealing ring at the bottom of the spring, so that the sealing ring and valve tightly held together, so when the outside force exceeds the preload of the spring, the switch is very light.Four, long service life: has been widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rockets and other departments, as well as people's daily life.
- 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: 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?
- First, 170psi pressure is not great, not excessive extrusion and rupture of polyethylene, but there will be stress relaxation phenomenon, is a long time there will be some loose, suggest you nut and pipe with tight mechanical connection is good, the data has not been studied, can only give you a suggestion: 24-48 hours after the installation is complete then a proper tight.
- Q: Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!
- I don't know. Solid geometry will happen. God knows me. Suddenly, barriers and French goods
- Q: Calculation formula of ball valve flow
- Q=Cd*A* (2*delta_P/rou) ^0.5Among them, Cd is the flow coefficient, generally take 0.6~0.8, you can go to check informationA is the opening areaDelta_P is the differential pressure between the inlet and outlet of the ball valveRou is the density of the fluid
- Q: What does "41H" mean in the ball valve Q41H-16?
- Q- ball valve;4- flange connection;1- through flow channel; (structural form)H-Cr13 stainless steel; (material)16- nominal pressure; (1.6Mpa)Body material: WCB, A105This is manual, and the valve body is WCB.
- Q: What's the meaning of the ball valve bore 14 "x 12"?
- The inner diameter of the two ends of the ball valve is 14 inches at one end and 12 inches at the other.
- Q: Domestic water pipe ball valve or cut-off valve?
- So, in the regular switch to the place, with the ball valve convenient, in the need to adjust the flow of the place and do not need to switch regularly, with a good cut-off valve.
