Main Features of PP-R Globe Valve

1, Health, non-toxic:

    The various parts of the pipeline system consists of PP-R pipes and fittings constituted can be completely non-toxic, health indicators in line with GB / T17219 standards.

2, Does not rust:

    PH value can withstand a wide temperature range, in the range of 1 to 14, a high concentration of acid and alkali corrosion.

3, Wear-resistant, non-fouling:

    PP-R pipe and tube inner wall smooth, uniform flow resistance is small and does not scale.

4, Reducing vibration and noise:

    PP-R pipe has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.

5, Anti-cracking:

    PP-R materials excellent elasticity makes pipes and fittings sectionally With frost expansion of the liquid together without bursting.

6, Anti-condensation, heat loss is small:

    PP-R material is a poor thermal conductor, reduces condensation and reduce heat loss less.

7, Anti-electric corrosion:

    PP-R material is a poor conductor of electricity can avoid corrosion. Complete specifications: 10-30 optional

Q:What domestic PPR ball valve can withstand acid and alkali?
Yue Yue PPR ball valve products are made of pure raw materials, mainly used in water supply and other plastic piping systems for industrial use. You can rest assured that the use of Hong Yue products
Q:What is the difference between ball valve and plug valve?
The main advantages of plug valves are as follows:Suitable for frequent operation, quick and easy opening and closing.Fluid resistance is small.The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance.Good sealing performanceFree from the direction of installation, the flow direction of the medium can be arbitrary.No vibration, little noise.Plug valve installation and maintenance should pay attention to the following matters:Leave the valve handle in a rotating positionCannot be used as throttling.
Q:Home PPR pipe ball valve, which is good?
Brother, brother to do plumbing business for more than 10 years, to be conscience, you'd better use the cut-off valve, ball valve in the South with the north, with cut-off valve, I was in Jiangsu, Taizhou, Jiangsu here have Taizhou as the boundary, the cut-off valve generally more in Taizhou Xinghua City, Taizhou Jiangyan Taixing Jingjiang more have ball, but the ball after the bad ball will change to buy the same brand, but also the same type, so that we can have, to buy is to cut off the new hot. Some hydropower workers have done you a dead distance, you can not re - hot, only in the water and electricity market crazy looking. But if the ball valve has the same brand, bad, they can exchange, very simple. The stop valve is broken. You should find a plumber to pay for it. But, the valve is not easy to bad, and indeed, the bad, you have to find the master for the spool, there must be professional tools, the spool is the same, so do not worry, not yet. Ball valve is also good, not easy to bad, but partial expensive, we use the ball valve Cowell tube industry, quite good. Total copper. There's one in Jiangyan that's on sale. The quality is absolutely OK
Q:Would you please tell me why the spring is placed in the valve seat? What's the function?
To put the spring ball valve must be big ball valve! Or fixed ball valve?! Fixed ball valves, as the name suggests, the ball of the valve is fixed, not right and left swing! Therefore, the valve seat should be added to both sides of the spring, the seal pushed to the valve core to seal up! The spring can also reduce the impact force of the material of the valve Wenzhou Songjiang pipe valve Co., Ltd. specializing in the production of stainless steel ball valve! Songjiang brand valve! Globe valve! Gate valve! Check valve! High temperature ball valve! Electric ball valve! pneumatic valve
Q:Calculation formula of ball valve flow
The sectional area of diameter of DN15, DN25 and DN50 is respectively:DN15:15*3.14/4=176.625 mm, 0.0177 square decimeter.DN25:25*3.14/4=490.625 mm, 0.0491 square decimeter.DN50:50*3.14/4=1962.5 mm, 0.1963 square decimeter.A pipe flow rate of V=4 M / s V=40 decimeter / s, and the 1 liter =1 cubic meter, the pipe flow respectively (cross-sectional area multiplied by the velocity):DN15 pipe: flow Q=0.0177*40=0.708 L / sec,It's 2.55 cubic meters per hour.DN25 pipe: flow Q=0.0491*40=1.964 L / sec,It's 7.07 cubic meters per hour.DN50 pipe: flow Q=0.1963*40=7.852 L / sec,It's 28.27 cubic meters per hour.Note: a flow rate must be given to calculate the flow rate, which is calculated in accordance with 4 meters per second. Reference: http://zhidao.baidu.com/question/77687541.html answer: good night dream | six | 2010-5-24 22:46It's 600 cubic meters / hour!Flow Q=600 m3 / h = 0.167m^3/sThe flow rate is V=4Q/ (3.1416D^2) = 4*0.167/ (3.1416*0.090^2) = 26.25 m/s, and the flow velocity is very large!It could be 600 cubic meters per day:Flow rate Q=600 m3 / day = 0.00694 m^3/sFlow rate V=4Q/ (3.1416D^2) = 4*0.00694/ (3.1416*0.090^2) = 1.09 m/s flow rate is normal.
Q:Daily maintenance of ball valve
The new parts need to be cleaned before assemblingThe assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities, foreign matter contamination, adhesion or remain in part into the cavity on the surface or, if the packing is micro discharge, to lock the stem nut.Note: do not lock too tight, usually lock 1/4 circle to 1 laps, the leak will stop.(A) disassemblyMake the valve in a half open position, flush and remove dangerous substances that may exist inside and outside the valve body.Close the ball valve, remove the connecting bolts and nuts on both sides of the flange, and then remove the valve completely from the line.In order to remove the drive - actuator, a connecting bracket, lock washer, stem nut, butterfly spring, glam, wear plates, valve stem packing.Remove the body cap connecting bolts and nuts, separate the valve cover from the valve body and take off the valve cover washer.Make sure the ball is in the "off" position, which can be easily removed from the valve body and then removed from the valve seat.A hole in the body downward nudge stem until completely removed, and then remove the packing ring and the O.Caution: Please operate carefully to avoid galling, stem surfaces and body packing box seals.B) reassembleCleaning and inspection of the parts removed, it is strongly recommended to use spare parts package replacement valve seat and valve cover, gaskets and other seals.Assemble in reverse order of disassembly.Cross the locking flange bolts with the specified torque.Lock the stem nut with the specified torque.
Q:Open the pressure relief valve core hole with what
Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need 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.
Q:Heating live catch valve DN15 straight DN15 angle what does that mean?
Look at the following two pictures to see: one is straight through, and the other is 90 degrees bend.
Q:About the characters on the ball valve (what do s and O mean?)
That's almost what it means. To be exact, S is SHUT and O is OPEN
Q:What does "F" and "C" mean in the Q11F-16C of the ball valve?
This model is not international standard number, but still can see, of which, F refers to the sealing material: fluorine plastic, C refers to the body material: carbon steel.
