Repair note of Hard seal ball valve

     Summary

     Have a long life and free repair period, will depend on the following factors: the normal working conditions, to maintain harmonioustemperature / pressure ratio, and the reasonable corrosion data

Be careful

    The valve in the closed state, the valve body remains fluid under pressure

    ● Repair, remove line pressure and the valve is in the open position

    ● Repair, disconnect the power or gas source

    ● Repair, the actuator and the support from the

    ● Must identify the valve on the downstream piping, pressure has indeed dropped, attempting to disassemble the operation

     The decomposition and re assembly must be careful to preventdamage to parts of the sealing surface, especially non-metallicparts, remove the O - ring, use special tool

     ● Bolts on the flange must be tightened symmetrically, evenly,gradually

     The cleaning agent should be with the ball in the rubber parts,plastic parts, metal parts and the working medium (such as a gas)are compatible. Working medium for the gas, the gas can be used(GB484-89) to clean metal parts. Pure water or alcohol cleaning with non metal parts

     ● Decomposition down the individual parts can be cleaned using immersion method. Metal non metal still did not break down the leftcan be used to clean fine clean silk impregnated with cleaning agents (to prevent adhesion of fiber loss on the part) scrub. To remove all the adhesive on the wall of the grease, dirt, rubber product, dust cleaning

     ● Non-metallic parts should be cleaned immediately removed from the cleaning agent, not a long time soaking

    ● Need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not a long time on hold, otherwise it will rust, the dust pollution

    ● Before the new parts in the assembly also need clean water

    ● Use grease lubrication. Greases are compatible with the ball valvemetal materials, rubber parts, plastic parts and the working medium.Working medium for the gas, can be used as special grease 221.Seals installed in the groove on the surface coated with a thin layer of grease, in the rubber seal is coated with a thin layer of grease,coated with a thin layer of grease on the valve stem sealing surface and the friction surface

     ● The assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities,foreign matter contamination, adhesion, or stay on the surface or in part into the cavity.

The working principle of ball valve seal

     Ball valve sealing material pairing for the ball valve metal to metal.

    Classification

   1).One-way sealing: only in the direction of the valve seal sealinglabel direction.

   2).Two-way sealing: can be sealed in two directions.

    Structure form

    Structure of ball valve is divided into floating ball and fixed ball type,connection form for the flange connection, welding connection and screw connection.

Conveyor Chain

     Working principle

      Hard seal ball valve, hard seal ball valve manual steel surface by spraying technology advanced, through the processing of different kinds of working conditions, maximum hardness up to HRC78. Theseal valve seat, maximum hardness up to HRC72. The matching grinding of ball and seat valve sealing surface, the sealing area areall precision ground. 

      Suitable for high temperature and high pressure water, steam, oil, coal, fiber, consistency and corrosive medium, and the medium with particles. Metal sealing ball valvefloating ball and fixed ball two structural metal seat ring and the spherical contact, spring load by acting in the seat ring even theseat ring and the spherical form a seal.

      Because the spring load so that the auxiliary sealing expansion, thesealing between the valve body and the valve seat. Spring loadenough to provide reliable seal between the valve seat and ball, on the condition of low pressure, the valve seat sealing surface and the sphere can be designed between the sealing grease injection system.

Theory to calculate the weight of large flange refers to

    Large flange refers to the flange exceeds the relevant departments of the state specified size. Generally refers to the flange size above DN2000. This product is full of welding products, no screw thread,are often used to DN15-DN100 specifications. 

      The nationalstandard flange GB/T9119-2010 0.25MPa to full size, standard 1.6Mpa is DN2000. The 2.5MPa standard is the greatest pressurein the DN800. Making such flanges are to make constructiondrawings to production. Production process of forging and rolling and splicing three. Product size is too large can only be in process of rolling and splicing.

    Calculation method of theoretical weight

    Large flange (Tan Gang) theoretical formula:

     1.First (outer diameter and inner diameter) divided by 2 results.

     2.Then (outside diameter and the above results) X the above results X0.0246615X thickness

    After the above two steps, it studied the weight of large flange.

    For example: outer diameter 2600mm, inner diameter 2400mm,thickness of 50mm carbon steel large flange flange

   (2600-2400) /2=100mm

    (2600-100) x100x0.0246615x0.05=308.2688KG

     The weight is generally in the two decimal place four to five homes in.

The production process of large flange

      Large flange refers to the flange exceeds the relevant departments of the state specified size. Generally refers to the flange size above DN2000. This product is full of welding products, no screw thread,are often used to DN15-DN100 specifications. The nationalstandard flange GB/T9119-2010 0.25MPa to full size, standard 1.6Mpa is DN2000. The 2.5MPa standard is the greatest pressurein the DN800. Making such flanges are to make constructiondrawings to production. Production process of forging and rolling and splicing three. Product size is too large can only be in process of rolling and splicing.

Product process

       The first plate cut into the appropriate note, note the lengthaccording to the large flange specifications. Then roll ring machinerolled into a circle, electrode the interface of firm welding, weld for the X spectrum test. And then press the pressing, processing line,chamfering process by lathe processing, finally pierce bolt holes by the indexing disc with drilling machine. 

       When a. When a bolt is not the bolt hole on a large flange weld areas.

Rolling flange forging of lower cost than. But some large flangeforging does not come out. The number of such products is the use of theoretical weight to weight, in the calculation, is not thewaterline, stop, bolt hole chamfering, weight lose. 

      Flat productprices low, but if a large flange processing dovetail groove likeprocesses or thickness thin price will be higher. The reason is acomplex processing technology and thin and thick spends theprocedure is the same. Theoretical weight is according to the following formula to calculate the.

Characteristic parameters and processes used carbon steel flange

      Characteristics and parameters

     Carbon steel flange close and reliable. It has two sealing surface,and the current valve sealing surface material widely used plastic,good sealing performance, and can be completely sealed. 

     Because the carbon steel flange in the opening and closing process is clean,so can be used with suspended solid particles of the medium.Model Q41F--16C Q41F--25C American Standard A105 about 0.9% (the standard is 1.05Max with carbon content decreases to 1.65%Max) to the 16Mn GB content about at about 1.3% (1.2% ~1.6%) S25C standard would be relatively low below 0.6%.

     Common process

     Production technology of forging, casting, plate rolling, plate cuttingetc.

     The forging the highest price in second, plate products, casting products, the lowest. In terms of quality, the best rolling forging,second, the third casting. But forging diameter generally smaller.
