Nhà sản xuất chuyên nghiệp của van bán cầu lệch tâm điện
Our professional manufacturer of electric eccentric hemispheric valves specializes in six product lines based on their application: general-purpose valves, pipeline valves, slurry valves, gas valves, petrochemical valves, and pulverized coal injection valves. We offer manual, khí nén, and electric transmission methods, eight pressure levels (PN 0.25 to 10.0 MPa), and hundreds of specifications (40 to 00 for the largest eccentric hemispheric valve).
Professional manufacturer of electric eccentric hemispherical valves Application Areas
It is an upgraded product for gate valves, van cầu, Y-type valves and ball valves in the petroleum, hóa chất, luyện kim, electric power and gas industries. It has been used in coal powder injection in the steel industry, slurry, mother liquor and alumina powder transportation in the alumina industry, hydraulic (or dry) ash removal in the power industry, petrochemical industry, gas industry and other occasions.
Professional manufacturer of electric eccentric hemispherical valves Applications:
Universal valves: Rationally designed and compact, they offer low flow resistance, excellent sealing, and easy and flexible operation. They are particularly well-suited for low-pressure pipelines handling media such as water, nước thải, hơi nước, and paper pulp. They can be equipped with electric or pneumatic actuators, enabling remote automated operation. (For non-corrosive media such as water, hơi nước, nước thải, paper pulp, and mud)
Professional manufacturer of electric eccentric hemispherical valves Advantages:
1. The side-mounted design is compact and lightweight, making it suitable for applications requiring limited installation space.
2. Kháng chất lỏng thấp, with a resistance coefficient equivalent to that of a pipe section of the same length.
3. Cấu trúc đơn giản, compact size, và trọng lượng nhẹ.
4. A cutting function that can cut debris (such as branches and textile bags) from the medium when closing.
5. Chặt chẽ và đáng tin cậy: The sealing surface of ball valves is widely made of plastic, which provides excellent sealing properties and is widely used in vacuum systems.
6. Easy operation and quick opening and closing: A simple 90° rotation from fully open to fully closed facilitates remote control.
7. Bảo trì dễ dàng: The ball valve has a simple structure and the sealing ring is generally removable, giúp bạn dễ dàng tháo rời và thay thế.
8. Khi mở hoàn toàn hoặc đóng hoàn toàn, the sealing surface between the ball and the valve seat is isolated from the medium, preventing erosion of the valve sealing surface when the medium passes through.
9. Nó có một loạt các ứng dụng, với đường kính từ vài mm đến vài mét, and can be used from high vacuum to high pressure. When the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.
Professional manufacturer of electric eccentric hemispherical valves Design Standards:
Design and manufacturing standards comply with: GB12237-1989, ASME B16.34, API 6D general purpose valve flange and butt-weld steel ball valves.
Dimensions comply with: GB12221, ASME B16.10.
Connection end dimensions comply with: JB/T79, GB9113, HG20592, ASME B-16.5A, ASME B16.25.
Inspection and testing comply with: JB/T 9092, GB/T13927-1992, API 598; general purpose valve pressure test.
Fire protection design complies with: API 607.
Please follow the following instructions for installation when purchasing our products:
a: Remove the protective caps on both flange ends and flush with the valve open. b: Before installation, the entire valve must be tested using the specified signal (điện hoặc khí nén) to prevent vibration from transport that may affect performance. Installation is permitted only after passing the test (wiring must follow the electric actuator wiring diagram).
C: Before connecting to the pipeline, flush and remove any remaining impurities from the pipeline (these impurities may damage the valve seat and ball).
d: During installation, do not use the valve actuator as a lifting point to avoid damage to the actuator and accessories.
e: This valve should be installed in a horizontal or vertical position on the pipeline.
f: The pipeline near the installation point must not sag or be subject to external forces. Use pipe supports or other supports to eliminate pipeline deviation.
g: After connecting to the pipeline, cross-tighten the flange bolts to the specified torque.
When the application is very important or the environment is complex, please provide design drawings and detailed parameters as much as possible, and our technical engineers will review and check them for you.
