    Non-standard valve is a valve without clear performance standards, its performance parameters and size are in accordance with the needs of the process and special custom


    Non-standard valve is a valve without clear performance standards, its performance parameters and size are in accordance with the needs of the process and special custom, in its does not affect the use of performance and safety can be free to design and change the size, parameters, etc.. But its machining process or follow the relevant provisions of the NATIONAL standard.

    Non-standard valve design from the overall consideration of rationality and feasibility, design in addition to rely on the traditional theory also need more innovative research and development, so generally there are elites in the industry to complete similar work, completed by engineers to hand over drawings.

    Non-standard valve types are divided into sewage valve series (gate, flap door) and metallurgical valve series (ventilation butterfly valve, gate valve, blind valve, discharge valve, etc.)

    1. Sewage valve series

    Intelligent stainless steel two-way sealing gate of Laos South Courtyard passes hydraulic pressure test perfectly (2021-06-17)

    Nanyuan Intelligence recently completed the production of 1000x1000mm, 1200x1200mm bi-directional sealed steel gates and successfully passed the hydraulic test.

    This batch of gate is the attached gate exported to Laos, ss304 material, bevel gear operation. The gate is required to be able to withstand water pressure in both forward and reverse directions to achieve sealing. Because export products have higher quality requirements, they also need to be tested as required.

    Nanyuan intelligent has passed ISO9001 and API international quality management system certification, with a perfect quality assurance system and advanced management mode.

    Steel gate is widely used in drainage and irrigation, hydropower station, reservoir, river, environmental protection, sewage treatment, aquaculture and other water conservancy projects. Using rubber sealing, anticorrosive way for the surface of sand blasting rust, products can be produced according to the drawings provided by users.

    Steel gate is mainly composed of door frame, gate board, sealing strip, hanging block nut and other components. The sealing surface is inset with P-type rubber strip to ensure the sealing and durability. After long use and wear, it can ensure the normal work by the height of the wedge pressing block. It has the characteristics of reasonable structure, good sealing, easy installation, adjustment, use, maintenance and reliable performance.

    Material of main parts:

    Gate slot: Q235B or 304 stainless steel, etc

    Door body: Q235B or 304 stainless steel

    Sealing rubber: epDM rubber

    Screw: 20Cr13 or 304 stainless steel

    Fasteners: 45# or 304 stainless steel, etc

    Main features:

    1. Light weight: about 1/3 weight of cast iron gate;

    2. Corrosion resistance: acid and alkali resistance and most corrosive chemicals and sewage, sea water;

    3. Good sealing: rubber to metal seal, sealing apron is hollow structure, good sealing performance;

    4. Small torque: light weight for the door panel, small friction resistance between the door panel and guide rail, so that the operating torque of the handwheel is not greater than 100N;

    5. Independent structure: welding structure with reliable temperature and stiffness, high performance seals to ensure the effective opening and closing of the gate, independent seal and wedge design makes the gate open and close more reliable, and can be subjected to reverse water pressure;

    6. Long life: because only to the last small section of sealing contact between the door plate and guide rail, sealing and wear is very small; Stainless steel gate service life of more than 10 years, carbon steel gate service life of more than 5 years;

    7. Easy maintenance: the wedge block can be adjusted, after years of use, such as local leakage, just adjust the wedge block to increase the sealing apron compression can save time and effort, low maintenance cost;
