Q:One stainless steel ball, two pieces, three pieces of difference, use
Structural features of two piece ball valve:1, opening and closing without friction. This function completely solve the traditional valve because of the friction between the sealing surface and affect the sealing problem.2, top structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.3, single seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.4 、 low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.5 wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.6. Self-cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.
Q:What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
In general, both sides of the ball are wire interface, and hot melt ball valve on either side or side of the live connection with PP-R short tube, as a hot melt interface, so called hot melt ball valve. As for the use, there is no obvious difference, but the connection is different.
Q:Ball valve specifications 1/2 inches corresponding to DN?
[1] 1/2 is DN15, 3/4 is DN20, and 1 is DN25.[2] ball valve: ball valve (ball valve in the field of marine engineering and ships should be cut-off valve), refers to the ball with a circular hole for opening and closing parts, the ball with the stem rotation, in order to achieve Kai [1] closed action of the valve. Standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the square ball valve for the axis of the rotation of the valve.". Use 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. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.
Q:Difference between fireproof and antistatic ball valve and ordinary ball valve
Ha ha, that is, non sparking metal, alloy, copper, alloy, aluminum is all right
Q:The valve nominal 1/2, 3/4 is how much?
1/2 equivalent to the national standard of 15mm, 3/4 equivalent to GB 20mm. That is, DN15 and DN20
Q:What's the meaning of the ball valve bore 14 "x 12"?
Should refer to imports 14 inches, export 12 inches, this kind needs to make to order, at present domestic possibly not yet.
Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
Supplement: the above mentioned is just a pure design, such as the novice to do the design, checking and calculating of the general will, in fact in the reality of the design, the valve products have been very mature, as you say these are size, can refer to the same type with the specifications of the product parameters so, the more accurate calculation, experience is more important than calculation.
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:The working principle of the track type ball valve
No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.
Q:Principle of forced sealing ball valve
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.
