- Q: DN15 stainless steel ball valve 304 can withstand much pressure?
- All pipe attachments of the same nominal diameter indicated by the same nominal pressure PN have the same connection dimension as the end connection type.GB stainless steel ball valve pressure class PN: 1.6MPa, 2.5MPa, 4.0MPa, 6.4MPa, 10.0MPa and so on. These values correspond to how much stress you can bear.
- 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 are the differences and advantages between O ball valve and V ball valve?
- 5, high reliability1, the ball and valve seat a pair of sealing pairs, there will be no abrasions, rapid friction and other failures;2, stem into the built-in type, to eliminate the stem under the action of fluid pressure may be caused by the packing gland release flying accident hidden trouble;3 、 adopt antistatic and fireproof structure ball valve, which can be used to transport petroleum, natural gas and gas pipelinesV type ball valve structure of a right angle turn, can achieve flow regulation, according to the V type angle V type sphere, realize different proportions, V type ball valve and valve actuator and positioner supporting the use, the ratio can be adjusted V type valve adjustment for a variety of occasions, with a rated flow coefficient large, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. For control of gas, steam and liquid medium.V type ball valve for rotary type rectangular structure by V type valve, pneumatic actuator, positioner and other accessories; there is a similar more than 100 of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors, the shear capacity of strong.
- Q: PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?
- Dark valveThe blind valve is used to control the solar switch, and the double live ball valve connects the hot water pipe and the pipe, or the connection between the prefilter and the pipe, then it will be replaced in the future. The dark valve can be connected to the three pass.Globe valveBall valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". 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. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
- Q: What does the sealing surface of the ball valve stand for HF?
- HF is the abbreviation of two English words: "Hard Face", which means surface hardening. Usually surfacing is made of Tailai alloy (Alloy 6). Other surface hardening methods include hard chromium plating. This method is used more in the ball valve. But hard chromium plating is prone to small cracks, which reduces its corrosion resistance.
- Q: I've seen a lot of hot water projects. Why do most of them use globe valves, and ball valves are seldom used?.Globe valves have those benefits compared to ball valves (because the cut-off valve is more expensive, I think it is more expensive and more useful. It must have some advantages in that respect.)Is the stop valve more durable than the ball valve?What are the specific differences between the two PPR valves?
- Yes, now the globe valve is more than the ball valve with more people, and its main or cut-off valve, a lot of adjustability, and most can be universal.Specific differences are as follows:Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.The cut-off valve is a forced seal type valve, so when the valve is closed, the valve must be applied to the pressure, to force the sealing surface is not leaking. When the medium into the valve six from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault. In recent years, the emergence of self sealing valve, globe valve replaced by medium flow on the top of the valve into the valve chamber, then in the medium under pressure, the valve off a small force, and force open the valve, stem diameter can be reduced accordingly. At the same time, in the role of media, this form of valve is also more stringent. China's valve "three to" has stipulated that the flow direction of the cut-off valve should be top-down.
- Q: What are the CF8 and CF3M marks on the stainless steel ball valves?
- Hello, CF8 stands for 304 material, and CF3M stands for 316L material. It's stainless steel
- Q: Into the tap valve, with globe valve or ball valve?
- Water valve at home as far as possible not to use the form of valve, gate valve for water, slag better, shut down with the next valve and ball valve.
- Q: DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
- 3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more appropriate.
