Accumulator type hydraulic slow retreat butterfly valve

Accumulator-type liquid-controlled slow-closing butterfly valve is based on accumulator energy storage to do auxiliary power source to drive the valve opening and closing. Making the valve no electricity in time, the energy stored in the accumulator can guarantee the valve open and close once. Accumulator-type hydraulic butterfly valve gear rack and rocker two structures

Valve mainly by the valve body, transmission, hydraulic station, electric control box and other four parts.

Valve body by the valve body, disc, stem, slide bearings, seal components and other major components.

Accumulator liquid-controlled slow-closing butterfly valve generally horizontal layout; can also be used according to user requirements vertical layout.

Transmission diameter DN≥1400 using side panels, rocker and other connections, transmission components, diameter DN <1400 using rack and pinion gear.

Transmission cylinder with slow closing time control valve. Users can go according to the design to be adjusted.

Hydraulic stations include pump units, hand pumps, accumulators, solenoid valves , relief valves, flow control valves , globe valves , hydraulic manifolds, fuel tanks and other components.

Accumulator system, the accumulator for the valve opening and closing to provide the main power source.

The flow control valve is used as the on-off valve time adjustment, the user can adjust the valve switch speed according to the design requirements.

Manual pumps are used for system commissioning and special case valve opening and closing.

Hydraulic system solenoid valve features: the solenoid valve power butterfly valve, loss of power valve protection Paul lock; use of other types of action should be specified when ordering.

The hydraulic system and the valve body are generally installed separately, but also can be installed as a whole. Users without special instructions for the split installation. Accumulator liquid-controlled slow-closing butterfly valve with vertical arrangement are split when installed.

Accumulator type liquid control retarder butterfly valve technical specifications

Note: Other relevant standards and foreign standards can be used. The flange size can be made according to user's requirement, but it should be stated in the ordering contract

Accumulator type liquid controlled slow closing butterfly valve product description and connection dimensions

The valve electrical control system according to the main logic component type is divided into ordinary type and PLC intelligent control type, the factory package is generally normal type, PLC intelligent control type to be specified when ordering. Each type is divided into the following several main conditions:

Open the valve centrifugal pump conditions (including centrifugal mixed flow pump): first start the pump, delay a predetermined time after the open valve, or valve at the same time open.

Off valve centrifugal pump: the valve closed to a certain angle, and then stop the pump. Or the same valve with the pump.

Open the axial flow pump conditions (including axial flow mixed flow pump): the valve open at the same time, or open the valve to a certain angle, and then start the pump.

Shut-off valve axial flow pump: the same valve

Opened valve turbine conditions: first open bypass valve balance pressure, and then open the valve.

Off valve turbine conditions: the main valve is closed at the same time open the bypass valve, to be closed when the main valve bypass valve.

The valve electrical control system is equipped with local control loop and remote linkage control loop. Local control loop is mainly used for on-site debugging, the normal work are generally used remote linkage control loop.

Pump power AC380V, control uninterruptible power supply DC220V, or other power levels AC220V, DC110V, etc.

Wire Grip

Wire grip:

Introduction:

Wire rope cable grips is power, telecommunications, railway electrification of overhead line construction and maintenance tools commonly used in the grip line. Wire rope cable grips It's so easy to use, wear well, lightweight, quality assurance: ISO9001: 2000.

Card line due to the use of different conditions, different varieties and specifications of the grip the wire, divided into: Aluminum Wire Card thread; insulated wire card line; strand card line (for strand); ground card line; single peach card line; double peach card line; breaststroke card line; anti-twist rope card line.
