DINKONDA GLOBAL Linear Hydraulic Pneumatic Cylinder For Power Plants High Power

Product Specification

DINKONDA GLOBAL Power Plants Special High Power Heavy-duty Fork Type Dual Cylinder Hydraulic Buffer Manual Emergency Double Acting Pneumatic Valve Actuators

Product Overview
This device is developed by DINKONDA GLOBAL and belongs to a high-power heavy-duty fork type pneumatic actuator. It integrates three major functions: dual cylinder pneumatic drive, external hydraulic buffer speed regulation, and independent manual control lever; Specially designed for large-diameter flue gas dampers, ventilation butterfly valves, and pipeline shut-off valves in thermal power plants and chemical industries, it can achieve pneumatic remote control, hydraulic slow opening and closing, and manual forced opening and closing under fault conditions, suitable for harsh working conditions with large impact loads and the need for buffering and shock absorption.

Structural Composition
1. Bilateral symmetrical drive cylinder
Two thick red cylinder assemblies on the left and right, with a rod type fastening cylinder head, and high pressure bearing strength of the cylinder body; Dual cylinder synchronous output torque, sufficient power, suitable for driving super large air doors and butterfly valves.

2. External hydraulic damping speed regulating cylinder
Equipped with an independent hydraulic buffer cylinder on the side, relying on oil circuit throttling to control the opening and closing speed of the valve, buffering the impact, preventing the valve from quickly closing and hitting the valve seat, and preventing water hammer and vibration in the pipeline.

3. Integrated manual emergency operation mechanism
An extended manual operation handle is installed below the box, which can manually open and close the valve in case of gas supply interruption, equipment maintenance, or emergency, meeting the mandatory safety regulations of the power station.

4. Central fork transmission box
The internal roller fork transmission structure automatically amplifies the output torque at the end of the stroke, overcoming the valve opening and closing resistance caused by dust jamming and high-temperature media; The upper end is equipped with a valve installation flange.

5. Stainless steel complete set of gas pipeline components
External metal trachea, joint control valve components, clear gas path layout, convenient for later maintenance and debugging of gas supply pressure.

Product Features
1. Dual cylinder high-power output
Symmetrical dual cylinder structure, high output torque, capable of driving DN1200-DN2800 large-diameter flue gas baffle doors and air duct butterfly valves; Balance the operating force and reduce the working vibration.

2. Hydraulic buffer speed regulation
Independent hydraulic damping cylinder, capable of independently adjusting the speed of valve opening and closing, achieving slow opening and closing, eliminating valve impact, pipeline water hammer, and air duct impact noise, and protecting the valve body and pipeline system.

3. Pneumatic manual dual control mode
Remote pneumatic control under normal operating conditions; During gas loss, power outage, and shutdown maintenance, use an external manual lever to directly control the valve to ensure pipeline safety.

4. Double acting gas retention
Double acting chamber structure, the cylinder is locked after the gas source is lost, and the valve maintains its original opening without accidental closure or opening.

5. High strength anti-corrosion body
The whole machine is coated with red wear-resistant and anti-corrosion paint, and the oil cylinder and air cylinder are resistant to dust, high temperature, and humid flue gas environment, suitable for harsh working conditions such as desulfurization and denitrification in power plants and induced draft fan flues.

6. Complete expansion accessories
Electromagnetic valves, explosion-proof limit switches, air source triplets, intelligent valve positioners, and valve position feedback transmitters can be installed.

Application
1. Thermal power generation industry: boiler desulfurization and denitrification flue butterfly valve, induced draft fan/supply fan inlet baffle door, hot air duct valve, large circulating water shut-off valve;

2. Petrochemical industry: high temperature flue gas pipelines, ventilation dampers, large angle stroke valves that require buffering opening and closing;

3. Metallurgical, heating pipeline network, large ventilation baffles for sewage treatment plants, water supply and drainage slow closing butterfly valves;

4. It is commonly used in critical safety pipelines and has strict requirements for buffering, shock absorption, and emergency manual control.
