Stainless steel flanged penstock can realize seamless connection between stainless steel flanged penstock and pipelines, channels and well bodies without complex embedded construction, which greatly shortens the project installation cycle. At the same time, the flange detachable structure makes the maintenance, seal replacement and component maintenance of stainless steel flanged penstock do not need to dismantle the whole equipment, and only need to disassemble the flange connection part to complete the operation, which greatly reduces the operation and maintenance difficulty, and is one of the penstock gate categories with the best operation and maintenance convenience at present.

3. Multiple Sealing Design, Zero Leakage Opening and Closing Control

Stainless steel flanged penstock adopts two-way water stop sealing structure, matched with customized EPDM rubber seals and stainless steel sealing surface double sealing design, which can realize forward and reverse two-way zero leakage sealing, and the sealing performance meets the industry zero leakage standard. The seals of stainless steel flanged penstock are made of anti-aging and wear-resistant materials, which can withstand millions of opening and closing without obvious wear. At the same time, the seals can be replaced quickly without secondary processing of the main body of stainless steel flanged penstock, so as to ensure the long-term sealing stability of penstock valve and eliminate the hidden danger of the project caused by medium leakage.

4. Stable Opening and Closing, Accurate Flow Regulation

Stainless steel flanged penstock adopts an integrated guide rail frame design. The gate plate and the guide rail adopt high-precision clearance fit, matched with self-lubricating guide sliders, which can realize jamming-free and noise-free stable opening and closing of stainless steel flanged penstock, and the opening and closing torque is far lower than that of traditional gate equipment. Stainless steel flanged penstock can be matched with a variety of opening and closing driving devices such as manual, electric, hydraulic and pneumatic, which can realize on-site manual control and remote automatic control, accurately regulate the medium flow and on-off state, adapt to the control needs of various automatic water conservancy projects, and is the core penstock valves equipment in the intelligent water system.

5. Sturdy Structure, Adaptable to Multi-scene Working Conditions

Stainless steel flanged penstock adopts an integral frame reinforced structure design. The frame, door plate and guide rail are all reinforced with reinforcing ribs, which can withstand high water head water pressure impact without deformation and cracking risk. Stainless steel flanged penstock can be customized with square, round, rectangular and other specifications and sizes according to project requirements. The water head pressure, installation method and driving method can be customized according to needs. Stainless steel flanged penstock can adapt to a variety of installation scenarios such as channel installation, pipeline installation, wall installation and well installation, and fully covers the use needs of various water conservancy, municipal and environmental protection projects.

(III) Product Structure Details and Scene Real Shot Description

(V) Installation and Maintenance Specifications

Before the installation of stainless steel flanged penstock, it is necessary to check that the specification size, flange standard and water head pressure parameters of stainless steel flanged penstock are consistent with the project design requirements, and check that the main body, seals, fasteners and other accessories of stainless steel flanged penstock are complete and undamaged.

During the installation of stainless steel flanged penstock, it is necessary to ensure that the flange butt joint surface is flat and clean, the sealing gasket is placed in place, and the bolts are evenly and symmetrically fastened to avoid poor sealing caused by the dislocation of the flange butt joint surface. The guide rail of stainless steel flanged penstock must be installed vertically, and the verticality deviation must be controlled within the industry standard range to avoid jamming of opening and closing caused by inclined guide rail.

During the daily maintenance of stainless steel flanged penstock, it is necessary to regularly check the sealing surface of stainless steel flanged penstock for wear and corrosion, and the seals for aging and cracking, and replace the damaged sealing accessories in time. Regularly fill the guide rail and opening and closing screw of stainless steel flanged penstock with grease to ensure stable opening and closing. Regularly check whether the bolts at the flange connection part of stainless steel flanged penstock are loose, and fasten them in time to ensure the long-term stable operation of flanged penstock.
