Principle of metal to metal floating ball valve
2018-10-22
The surface of the metal to metal floating ball valve adopts advanced spraying technology. Through the treatment of various working conditions, the highest hardness can reach HRC78. Seat cover treatment, highest hardness up to HRC72. The ball and seat are ground in pairs and all sealing areas of the entire sealing face of the ball valve are accurat... The surface of the metal to metal floating ball valve adopts advanced spraying technology. Through the treatment of various working conditions, the highest hardness can reach HRC78. Seat cover treatment, highest hardness up to HRC72. The ball and seat are ground in pairs and all sealing areas of the entire sealing face of the ball valve are accurately ground. The metal to metal floating ball valve is suitable for high temperature and high pressure water, steam, oil, coal, fiber, thick and corrosive medium, and medium with particles. Metal sealing ball valve has floating ball and fixed ball two structure metal seat ring contact with the sphere, by acting on the seat ring uniform spring load to seal the seat ring with the sphere.

1, sealed emergency grease Ambulance: due to the media in the foreign body or fire caused by the valve seat seal accidental failure, the grease valve provides a quick connection with the grease gun, convenient and quick injection of sealing grease into the valve seat sealing parts, The2, reliable stem seal and low operating torque: In addition to t... 1, sealed emergency grease Ambulance: due to the media in the foreign body or fire caused by the valve seat seal accidental failure, the grease valve provides a quick connection with the grease gun, convenient and quick injection of sealing grease into the valve seat sealing parts, The2, reliable stem seal and low operating torque: In addition to the standard seal ring, the packing gland is also set on the "O" type seal, double seal to ensure the reliability of the stem seal; additional graphite filler and Seal the grease to minimize the leakage of the stem after the fire. Stem slide bearings and thrust bearings make the Forged Trunnion Mounted Ball Valve easy to operate.3, full diameter or reduced diameter: according to the need to use full diameter or reduced diameter structure. Full diameter valve flow aperture and pipe diameter consistent, easy to clean the pipeline.4, the stem can be lengthened: According to the installation or operation needs, the valve stem can be lengthened. Cast Ductile Iron Ball Valve, especially for urban gas and other places need to lay the pipeline buried. The length of the stem is determined by the customer's needs.5, flexible operation: the use of a small coefficient of friction and good self-lubricating valve seat and stem bearings, greatly reducing the operating torque of the valve. So that even in the absence of sealing grease to provide the case, but also long-term flexibility to operate the valve. View Details
Application situation

Because ball valves are usually made of rubber, nylon and polytetrafluoroethylene as seat ring materials, its use temperature is limited by the seat sealing material.

Because ball valves are usually made of rubber, nylon and polytetrafluoroethylene as seat ring materials, its use temperature is limited by the seat sealing material. The cutoff of the ball valve is made by pressing the plastic seat between the plastic seat to complete (floating ball valve) under the action of the medium. The seat sealing ring is under certain contact pressure, the local area of the plastic deformation. This deformation compensates the fabrication accuracy and surface roughness of the ball and ensures the sealing performance of the ball valve.And as a result of the ball valve seat sealing used plastic, so in the choice on the structure and performance of the ball valve, want to consider the refractory of ball valve and fire prevention, especially in petroleum, chemical industry, metallurgy and other departments, the equipment and piping system of inflammable, explosive medium used in ball valve, more should pay attention to fire and fire prevention.

From the previous years the global economic crisis, to the subsequent ease and then to the current recovery, the economic changes also led to the valve industry forged steel ball valve manufacturers have been growing and changing. And why the common forged steel ball valve can now lead to the traditional industrial valve constantly changing innovation?The traditional forging ball valve manufacturers in the past few years has been in the development of relatively flat period. From the production process, forged steel ball valve compared to stainless steel ball valve manufacturing technology will be somewhat behind; and in overseas output, China's forging ball valve annual output of 3 billion US dollars, while the stainless steel ball valve can be as high as 5 Billions of dollars.Forged steel ball valve is divided into low pressure forged steel ball valve, high pressure forged steel ball valve. High pressure forged steel ball valve is based on the needs of users, in order to meet the vulcanization environment in the application of vulcanization cracking requirements, the series of high pressure forging ball from the design, selection, manufacturing, testing, surface and paint are strictly in accordance with the United States corrosion The engineer will be required by the NACE standard. Forged Trunnion Mounted Ball Valve is not only a wide selection of materials and materials are all surface with nickel plated 316 material, sealing the use of special polymerization special information. So that the valve is not only anti-corrosion, anti-vulcanization ability, fire, anti-static, good sealing performance, the use of a wide range of pressure and temperature range, full diameter and reduced diameter are available, and can be equipped with a variety of drive, chemical, ,Valve medium cavity stagnation of the medium due to changes in temperature and civil pressure, the media pressure to push the valve seat from the Cast Ductile Iron Ball Valve, to achieve the effect of automatic pressure relief, valve seat automatically reset the natural gas mining and transportation system ideal valve selection.High-quality features and characteristics of the scope of the forging high-pressure ball valve in the future changes in the valve market occupies an important leading position. Professionals predict that in the next 3-5 years, it is expected that 2025 forged steel ball valves will occupy 70-80% of the traditional valve industry market share, the new forged steel ball valve will continue to appear, even at home and abroad leading the other ball valve products.
