Liquid moving unloading gray ball valve is composed of valve body, ball, valve seat, stem, bracket, hydraulic drive and other components. Sealing ring with a combination of soft and hard laminated metal seal, with a metal seal and the advantages of flexible double sealing, seal with automatic compensation device for discharging the ball valve, has a very good sealing performance, long service life. Large hydraulic drive torque, with fast opening and closing, to ensure unloading ash pipe system, the most effective work characteristics. Removable gray ball valve for metallurgical systems blast furnace ash unloading device for use on the pipeline, and should be installed for vertical position to ensure ash can be smooth flow unloading. Use must be fully open or closed, forbidden to use for throttling, structure Main features: 1, the use of fixed ball (shaft support) structure. In order to reduce the operating torque of the ball valve and enhance the reliability of the seal to avoid displacement of the ball after pressure, so the ball valve structure of the fixed ball. This structure to maximize the valve opening and closing to ensure flexible, accurate alignment, not the size of the media pressure. 2, the seal: the use of soft and hard laminated metal seal combination, with a metal seal and the advantages of flexible double sealing, sealing strip with automatic compensation device for discharging the ball valve, has a very good sealing performance. The valve seat and the valve body are of a cylinder structure, which can ensure the integrity of the contact between the sealing surface and the spherical surface so as to ensure the life of the sealing; and the compensation device, when the sealing is normally worn, squeezes the sealing seat integrally onto the spherical surface, Compensate the wear and tear caused by the sealing gap, also extended the life of the sealing surface. 3, the drive form: The hydraulic drive device, with large torque, to avoid the movement of dead ends, to ensure rapid valve opening and closing, the valve can be opened and closed within 5 seconds, to switch the flexible and rapid. Unloading gray ball valve is evolved from the cut-off valve. It has the same 90 degree rotation action, except that the plug body is a sphere with a circular through hole or passage through its axis. The ratio of the sphere to the port should be such that when the sphere is rotated 90 degrees, the sphere should be fully spherical at the inlet and outlet to cut off the flow.

Unloading gray ball valve structure features: Unloading gray ball valve Three-way electric ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium. Unloading gray ball valve structure can be divided according to: floating ball, fixed ball, flexible ball. Unloading gray ball valve is mainly used to cut off or connect the media in the pipeline can also be used for fluid regulation and control, unloading ball valve compared with other types of valves, the angular stroke output torque, open fast, stable and reliable, widely used . Unloading gray ball valve Features: 1. Long service life, the use of self-lubricating sealing ring PTFE material. Unloading gray ball ball and seal ring micro-friction, effectively improve the service life. 2 small size, light weight, easy to install and maintain. 3. Unloading gray ball valve structure can be installed in any direction and any part of the pipeline. 4. Unloading the ball valve then stacked axial packing to achieve anti-corrosion A-class sealing temperature -28 ~ 300 ℃ of petroleum, chemical, thermal power stations and other conditions of the pipeline, cut off or connected to the medium for the media: water, Steam, oil, nitric acid, acetic acid, urea and other corrosive and highly oxidizing media. Mode of operation are: manual, pneumatic, electric, hydraulic and gas-liquid interaction. Hemp nuts, if you`re a bit unsure, are the whole Hemp Seed including hull (outer, crunchy shell) and heart (inner, soft heart). The Hemp Company`s own Hemp Nuts are grown by organic farmers and are naturally gluten free, are a great source of insoluble fibre, and are an absolutely delicious and incredibly nutritious snack!
