Metal hard seal ball wear-resisting pneumatic valve

the wear resistance of metal sealing ball sphere of pneumatic valve and pneumatic seat completely use a metal to metal seal way, in order to ensure the wear-resistant ball pneumatic valve under various temperature and pressure of reliable sealing, aiming at different operating conditions and requirements of users, you can use a variety of advanced sphere and pneumatic seat hardening technology, including supersonic spraying, special nickel-based welding, surface hardening, hard alloy spray welding, such as a sphere and pneumatic valve seat surface hardness can reach more than HRC, commonly higher can reach more than HRC. Sealing surface material heat resistance can reach ℃, higher reaches ℃. Material bonding strength can reach above PSI, sealing surface material also has the very good properties, such as friction resistance, impact resistance.
wear-resistant ball pneumatic valve is suitable for the Class to Class, the PN to PN of various pipelines, used to truncate or on line in the medium. Choose different material, wear-resistant ball pneumatic valve can respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media. Wear-resistant ball pneumatic valve drive mode for manual, worm gear drive, pneumatic or electric. Wear resistance pneumatic ball valve with flange, butt welding may be adopted.
wear-resistant ball pneumatic valve with pneumatic seat hardening technology, USES the advanced ball and prevent pneumatic valve under high temperature rise to death, excellent sealing performance, completely fireproof structure design, natural anti-static structure design, the function of blocking and discharge, etc.
ordinary metal sealing ball pneumatic valve, are all with two independent pneumatic valve seat seal, leak point more. And the clearance around the pneumatic valve seat, often have medium on the wear and tear, or in the place gathered, seriously affected the normal operation of the pneumatic valve, pneumatic valve seat damage. This series of pneumatic ball valve, its left side USES integration pneumatic valve seat, the pneumatic seat left for part of the pneumatic valve body, form the conjoined structure, reducing the leak point, such integration pneumatic seat to eliminate the medium around the pneumatic valve seat leakage, good shear self-cleaning function removes dust particles, resistance phenomenon.
conventional metal sealing ball pneumatic valve, ball hardening treatment is usually adopt surface chromium plated or ion nitriding, the hardening layer is very thin, so products antiwear performance difference caused by the short service life. Wear-resisting series pneumatic ball valve, sealing pair with supersonic flame spraying super wear-resistant tungsten carbide alloy, has the high hardness and wear-resisting performance.
wear-resistant ball pneumatic valve is learnt hard seal technology abroad and the design and manufacture, the use of special sealing structure, reliable sealing performance, achieve zero leakage. Pneumatic wear-resistant ball pneumatic valve ball and seat has good shearing self-cleaning function, eliminates the caused by dust particles bonding pneumatic valve seal jam phenomenon, appearance is still maintain normal hard seal ball of pneumatic valve and beautiful. Wear-resisting pneumatic ball valve of the seal with supersonic flame spraying super wear-resistant tungsten carbide alloy processing technology, with high hardness and wear-resisting performance, hardness of HRC ~, the service life of pneumatic valve is the conventional hard seal ball; Suitable for organic silicon and polysilicon project special conditions such as systems.
the pneumatic valve ball, wear resistance, corrosion resistance, easy to operation and self-cleaning function, is suitable for transporting slurry or impurity liquid pipeline system.

wear-resistant ball pneumatic valve standards
the design and manufacture standard: API D, API, BS, GB/T
structure length standard: ASME B. Flange standard, GB/T
: ASME B. , GB, JB, HG, SH, BS, DIN, JIS etc.
experiment testing standard: API, GB/T, ISO, GB/T, JB/T

how to correct the choose and buy of wear-resistant ball pneumatic valve
right choice wear-resistant ball pneumatic valve, pneumatic valve is to ensure that the wear-resistant ball in terms of equipment, pipeline it is more convenient to use one of the prerequisites. After all, the wear-resisting ball of pneumatic valve and trouble-free use cycle is very important, because it determines the whole pipeline system work efficiency. Choose wear-resisting pneumatic ball valve is a fairly important role in the pipe.
at present, the wear-resisting ball pneumatic valve demand chain is very big, this is the result of its use features and use very extensive. Special structure at the same time, at the same time of convenient installation, maintenance and maintenance cost is also very small. Below small make up he said, the choose and buy of wear-resistant ball pneumatic valve steps:
. Clear their equipment in the field of wear-resistant ball pneumatic valve USES, determine the basic working conditions and the basic situation of the equipment. Clear the nominal dimension of wear-resistant ball pneumatic valve and connection mode.
。 Determine the operating mode of wear-resistant ball pneumatic valve, and according to the basic parameters to the transmission medium and the choose and buy.
。 Determine chooses wear-resistant ball geometry parameters of the pneumatic valve, including the structure and basic size, length, the flange connection and the height of the open closed gear, bolt hole size number, the appearance of the wear-resistant ball pneumatic valve and so on.
the above is the choose and buy of wear-resistant ball pneumatic valve basic steps, hoping to bring help the choose and buy of pneumatic valve.
