Two-way floating metal hard seal ball valve including: the valve body, valve stem, sphere, the upstream seat and the downstream seat, the product of the valve body is equipped with entry and exit, interconnection between entry and exit of products, products of the upstream seat near the entrance from the product on the face of disc spring, located in the upstream of products and product of disc springs between the seat with the body of the product, the product of the body with the sealing machine and sealing machine, and products are preset distance between the upstream seat. This product provides a floating can realize two-way sealed hard seal ball Industrial Valves, reduce the cost, and simplify the complexity of operation, in addition, this product at the same time of guarantee to seal, can achieve reverse sealing, and can meet the sealing of high pressure and low pressure condition; This product by setting the sealing machine, enables the reverse the reliability of the seal to get effective guarantee. Hard seal ball valve, ball core, including body seat, shaft and guide sleeve, its characteristic is that the ball core, adopting the fixed support structure in the product of the seat contact with the ball core is equipped with a convex sets, in the product of the seat sealing surface with ball core installation has a lip seal type; Beside the product guide sleeve are installed on the axis of the seal. This product technical solution to solve the GSP technology of pulverized coal conveying special ball valve sealing unreliable, seal surface hardening layer falls off easily, the problem of large torque, at the same time solve the problem of the guiding parts easy to damage, but also improves the ability of valve abnormal anti jamming, need not with special pipeline purging gas.
The global market was valued at cast iron gate valve in os & y valve fire protection and is expected to reach a market value of y gate valve by resilient gate valve, with a CAGR of resilient seal gate valve during the forecast period.
We humbly ask you to use water gate valve and we guarantee that you would be in a great delight with using the product.
Further dialogue of Mech Valve between the approaches, the chapter concludes, could lead to actionable advice on more robust policies that drive both structural change and competitiveness upgrading.
