Q: What is the difference between floating and fixed ball valves?
Fixed ball valve is the ball with the lower stem fixed, pressure will not produce movement, therefore, in the design, two sealing ring must have sufficient preload to ensure that the valve seat and sphere seal, is a two sided forced seal. Thrust or sliding bearings are usually provided on the upper and lower stems of the ball.
Q: What does copper ball valve type Q11F-16T mean?
Q refers to the ball valve, 1 refers to the connection mode, the latter 1 refers to the straight through type, F refers to the sealing material, 16 refers to the nominal pressure of 10 times, T refers to the main material for copper material.
Q: Is the integral type split ball valve structurally identical?
Split type ball valve, the valve body by the main body and the cover body is composed of two parts, thread connection between the main body and the cover body is arranged at the connection of the sealing ring, an annular sealing ring and ball valve, valve rod, sealing gasket, valve stem nut, a handle, a fastening nut is arranged on the main body, there is another ring the sealing ring is arranged on the cover body, interface screw holes at both ends of the valve body are respectively processed in the main body and cover body. This structure of the ball valve, the ball cavity depth is relatively shallow, the ball cavity processing is more convenient.
Q: Are ball valves and float valves a thing?
Float valve is a branch of the ball valve.According to the transmission mechanism, the ball valve can be divided into two parts:1 pneumatic ball valve2. Electric ball valve3 、 hydraulic ball valve4, pneumatic ball valve5 、 electro hydraulic ball valve6, turbine drive ball valve
Q: What does "ball Q41F-16" mean?
Q- ball, 4- flange connection, 1- DC channel, floating ball, F- sealing material for fluorine plastic, 16- nominal pressure of 16 kg, the valve body material for gray cast iron. If you want to know the details of the valve named model establishment, can refer to the JBT-308-2004 standard.
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 situation is not normal, the reason is not between the upper PVC pipe and tighten the valve, now has been unable to tighten, in order to avoid the emergence Water Leakage situation, you can use a silicone rubber sealing between the valve and the pipe to be dry silica gel between the pipe and valve after no loosening of the situation.
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: Three electric ball valve type T and type L what is the difference?
Electric three way ball valve is a kind of valve, can be divided into L and T type.The T type can cause three orthogonal pipes to connect with each other and cut off third channels, thus diverting and merging the channels.Two pipeline L three ball type valve can only be connected mutually orthogonal, communicating with each other while maintaining the third pipeline, only as a distribution function.Type T and L type reversing diagrams are as follows:Turn left and turn right |
Q: How to distinguish between single and double ball valve?
I don't know what you mean by "single" and "double", but the ball valve can be divided into one, two and three.
Q: Daily maintenance of ball valve
Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution
