goggle valve

The valve is a reliable isolation equipment in gas medium pipeline. It is suitable for gas, gas and powder transmission pipeline in metallurgy, chemical industry, machinery, energy and municipal engineering systems. The chain wheel type goggle valve manual driving device is mainly used on the manual goggle valve requiring long-distance operation, and is assembled and connected with other parts of the valve through the valve driving device; By pulling the hand zipper strip, the remote manual operation of the valve is realized, so that the use of the valve is more flexible and is not limited by power and air source.

1.With its superior performance, the pneumatic sector blind valve provides a safe and reliable isolation device for the automatic control of toxic, hazardous and flammable gas pipelines in metallurgy, chemical, environmental protection and other industries. 2.The pneumatic blind valve can be controlled remotely by a single unit, or by multiple units connected to the network, and can also be operated manually by the valve itself under abnormal conditions.

▶Mainly composed of left valve body, right valve body, screw rod pair, flap, sealing ring, lever, hydraulic cylinder and other parts, and a rigid structure is formed by the base and support column. ▶Equipped with a clamping oil cylinder and a flap oil cylinder. The clamping oil cylinder drives the left and right valve bodies through a lever pair and a screw pair to complete the loosening and clamping action. The flap oil cylinder drives the flap to complete the switching action.

1.The stainless steel blind valve are mainly consisted of body,disc,disc seal ring,disc locknut,bonnet,bonnet gasket ect.The valve disc is used for cutting off or dredging the pipeline.The suitable medium can be water,oil,gas and the suitable temperature can be-29℃-150℃.The main property is simple structure and reliable performance. 2.A blind plate is installed in the middle of the upper one of the three lead screws, and the blind plate rotates around the axis. The following two lead screws are equipped with blind plate positioning blocks on the same position, which can prevent the blind plate from drifting when the blind plate rotates and avoid abrasion of the sealing rubber ring.

▷The google valve plate sealing ring adopts special silicone rubber sealing ring, and the sealing pair is special silicone rubber/stainless steel. The valve plate movement adopts two-way rolling structure. ▷In case of power failure or failure, the google valve can be opened and closed manually on site. ▷The shaft head seal of the transmission shaft of the traverse mechanism adopts the form of packing gland, which is reliable and easy to maintain. ▷The transversal mechanism is located above the valve and adopts stainless steel tooth pin drive, which is wear- resistant, corrosion-resistant and has a long service life.

▶Seal unaffected by piping misalignment ▶Absolute positive Shut-Off - "Man Safe" ▶Manual, electric, hydraulic and pneumatic actuation available ▶No spreading of pipe required ▶Render an absolute tight shut-off in blast furnace, basic oxygen, open hearth or other gas mains applications ▶Found in the Petrochemical, Steel, Pulp and Paper, Maritime and Oil ▶With renewable silicone sealing ring for absolute gas sealing.

1.Automated and simplified operating sequence without compromising safety principles. 2.Successfully used world-wide. 3.Refined sealing system. 4.Can be built to accommodate various operating temperatures. 5.Variety of duct installation positions to fit specific customer needs.​ 6.Choice of actuation to suit your needs.

▷The google valve is a reliable isolation device in gas medium pipelines, suitable for gas, gas and powder conveying pipelines in metallurgy, chemical industry, machinery, energy and municipal engineering systems。 ▷The google valve is a closed design structure, the valve body adopts a fully enclosed shell, and the gas in the pipeline during operation does not leak, avoiding environmental pollution, and has good resistance to external pipeline forces. ▷The electric device is installed on the outside for maintenance and inspection, and the safety performance of personnel close operation is high.

▷Absolute positive Shut-Off - "Man Safe". ▷No spreading of pipe required. ▷Seal unaffected by piping misalignment. ▷Manual, electric, hydraulic and pneumatic actuation available. ▷Simple, one man, spectacle changing from one side of the line. ▷Special anti corrosive coatings such as epoxy, PTFE. ▷316 SST as standard, other materials upon request. ▷Optional drain/purge connections. ▷Available in sizes from DN300) to DN1000.
