- Q: Electric ball valve installation need to pay attention to what?
- 8, electric and pneumatic valve in order that no special contract allows only vertically installed in the indoor use. 9, after the completion of the pipeline construction, all the valves on the pipeline line shall be opened and the residual dirt shall be removed.
- Q: What does "S" mean by ball valve Q11S?
- S is the body material code, plastic.
- Q: The difference between ball valve Q341F and Q347F
- 7: fixed ball valve, F: fluorine plastic valve seat sealStructural distinction:Floating ball: ball valve is floating, in the media under pressure, that the ball can produce a certain displacement, and tight at the outlet end of the sealing ring, to ensure that the export side seal, a single side forced seal.Fixed ball: the ball of the ball valve is fixed, the pressure does not produce movement, therefore, in the design, two sealing ring should be sufficient pre tightening force to ensure sealing, double sided forced seal.
- Q: The hot water pipe ball valve what brand alone?
- Such as the bathroom taps are generally alternating hot and cold water, will be pulled out from the faucet two hoses, and then connected to the wall, embedded in the wall of the interface is angle valve. Because the heating pipe at the corner of the shape of 90 degrees angle, and the ball valve is straight through, so the basic difference between angle valve and spherical valve is that the angle valve exports and imports into 90 degrees right angle. rn usually angle valve mainly plays four roles: rn transfer within rn out nozzle; when the water pressure is too large, can be adjusted in the triangle valve above, turn down; the rn with switch function, if the leading Water Leakage phenomenon, can promptly put the triangle valve off, instead of the total valve closed in the home.
- Q: What is the principle of forced sealing ball valve? How to achieve mandatory sealing function? Is it suitable for high pressure conditions?
- Structural characteristicsForced sealing ball valve combines the advantages of ball valve, gate valve and plug valve. It has the characteristics of good tightness, no wear and tear, erosion resistance, and on-line maintenance.(1) the bevel of the lower end of the forced seal lift stem provides a mechanical wedge tightening force to ensure continuous tight seal.(2) switch no wear, valve switching process, the ball deviates from the valve seat and then rotating, eliminating the friction of the valve seat, to solve the ordinary ball valve, gate valve and plug valve seat wear.(3) the anti erosion lifting stem realizes the rotation of the ball from the valve seat, and the ball and the valve seat perform the switching action without contact. When the valve is open and about to be closed, the fluid flows immediately along the sealing surface in the range of 360 degrees. When the fluid begins to flow, it can flush the impurities on the valve seat. To avoid the high speed fluid in common ball valve opening and closing the micro moments of local scour on the seat, even the harsh conditions of high pressure, can still ensure long-term zero leakage and tight sealing, improve the service life of the forced sealing ball valve.(4) no case single seat design avoids the valve cavity pressure increases and easy to jam problem.(5) good sealing performance, the ball and valve seat sealing surface after special hardening treatment, can not damage the integrity of the seal to meet the very harsh conditions of sealing requirements.(6) easy maintenance valve adopts top mounted structure. After decompression, it can be checked and maintained online, and the maintenance is simplified.
- 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: What's the difference between a one piece ball valve and a two piece ball valve?
- 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'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: For example, how many sizes and pressures are used in the two piece?
- A piece of ball valve is mainly manual, two piece ball valve for atmospheric pressure and high pressure, three pieces of ultra high pressure will be used, according to the actual caliber to determine
- Q: Home tap water valve (ball valve) half open or well open, open half is not love rust live?
- Open big, small, same, as long as the pressure is enough, enough flow does not matter. The effect is half open, with a sound.
