DBB double ball valve has two series of full diameter and reduced diameter. The inner diameter of the full diameter ball valve is the same as the inner diameter of the pipeline, which not only has small fluid resistance, but also is easy to clean the pipeline. The fluid resistance of the reduced diameter ball valve is much lower than the fluid resistance of the same caliber globe valve, and the weight is about 30% lighter than the same caliber ball valve, which effectively reduces the production cost and price, so it has been more widely used. DBB double ball valve (double plugging double discharge ball valve) is designed to replace the complex form of multiple valve connections in the traditional pipeline. Reduce the leakage points in the system, quickly realize the discharge, closing function. Double plug double discharge ball valve maximizes the installation space. The installation procedure is simplified. Reduces the pressure on the ductwork. Convenient instrument cleaning and maintenance, reduce costs. Products are widely used in electric power, petrochemical, metallurgy, Marine, petroleum, natural gas, gas, pharmaceutical and other industries of the hydraulic system pipeline.
Second, performance characteristics:
Stem anti-rush and effective sealing structure
The valve stem adopts the down-mounted reverse sealing structure with sealing gasket. The sealing force of the reverse sealing increases with the pressure of the medium in the valve chamber, so as to ensure the sealing effect of the valve stem. When the abnormal pressure of the valve chamber, the valve stem will not be rushed out. The packing adopts a reasonably designed V-shaped structure, which can effectively transform the medium pressure inside the valve chamber and the locking force of the external gland into the sealing force of the valve stem.
Fire-resistant structure
According to the needs of the user, the ball valve can be designed into a fire-resistant structure, when the sealing ring is burned in case of fire, the various sealing parts of the ball valve can form a metal-to-metal hard sealing structure, effectively prevent the spread of the medium and prevent the expansion of the fire.
With lock structure
For the valve installed in the field or to prevent the misoperation of non-staff, and in some cases where the handle is affected by the impact of misoperation, there is no locking hole in the fully open or fully closed position of the valve, and it can be locked when needed to play a safety insurance role.
Anti-static structure
Ball valve can be designed anti-static structure, that is, between the ball and the stem, the stem and the valve body set a conductive spring, so that the static electricity generated in the opening process of the valve can be passed through the electrostatic channel set into the pipeline into the ground, to achieve the purpose of removing static electricity. Avoid electrostatic ignition igniting flammable media to ensure system safety.
