Hydraulic control valve

MAIN FEATURES:

Hydraulic control valve is at present domestic and foreign advanced management and control equipment, mainly installed in the hydropower turbine inlet, used for water turbine inlet valve; or installed in the water, electricity, drainage and other types of feed water pump outlet of the pumping station, instead of check valve and gate valve function. When working, the valve and the pipeline host match,according to the principle of hydraulic transition process, by default the opening and closing process, the effective elimination of pipeline water hammer, realizes the pipeline reliable closure, to protect the pipeline system security role.

The company production of hammer pressure butterfly valve leave resistance coefficient is small, high degree of automation, complete function, stable and reliable performance, is my company designers based on wide collection,research, summarizes the domestic and foreign similar products performance,introducing the valve, hydraulic, electrical and other industries a number of research results, the plot thick and thin hair, development of a new generation ofintelligent energy efficient products. Company has strong technical strength, andaccording to the special requirements of users a separate design, multi rangemeeting the needs of users of the product.

Products in accordance with the control system - energy storage type is divided into hammer and the accumulator type two series, including weight control systemis divided into ordinary hammer, hammer type automatic pressure (B) and lockingtype automatic pressure hammer (S); the accumulator type control system isdivided into ordinary storage can type (X) and locked type accumulator type (XS).

The valve is mainly composed of a valve body, a transmission mechanism, a hydraulic station, an electric control box is composed of four parts.

The valve body has a valve body, a butterfly plate, a valve shaft, sliding bearings, sealing the main parts assembly etc..

The hammer is generally adopts a horizontal structure, the valve shaft adopts the half shaft structure.

The accumulator type generally adopts horizontal type; also can according to user requirements by use of a vertical layout.

The transmission mechanism is composed of a hydraulic cylinder, a rocker arm, a supporting wall (hammer and hammer, lever lock cylinder, etc.) connection,transmission component, chief executive of hydraulic drive, the valve off.

The transmission hydraulic cylinder is provided with quick view time adjusting valve, slow closing time adjusting valve and fast, slow off the angle valve.Adjustment range see page fifth 'special' parameters.

The horizontal layout, the transmission mechanism generally installed using the forward; from the field space limit can also be based on user requirements with anti loaded type. Hydraulic station comprises a pump unit, the manual pump,accumulator, electromagnetic valve, relief valve, flow control valve, the cut-off valve, hydraulic manifold block, fuel tank and other components.

The weight type automatic pressure system, the accumulator is used as thesystem pressure compensation.

The locking and weight type automatic pressure system, the accumulator is used as the system pressure compensation and lock the cylinder back lock.

The accumulator type system, is provided for the valve opening and closing the main power source energy storage.

The flow control valve for valve opening time adjustment, the adjustment scope sees fifth

The manual pump system for debugging and special conditions of the valve opening and closing.

The hydraulic system of electromagnetic reversing valve control characteristicsgenerally for function, namely: electromagnetic valves electric butterfly valve to open the valve, electric butterfly valve closed valves lost; otherwise for the reaction, namely the loss of electric butterfly valve off valve solenoid valve. The conventional matching electromagnetic reversing valve for function, usingreverse action should indicate in order.

The hydraulic system and the valve lift can be integral installation, also can be mounted separately. Users without special instructions for the integral installation.The accumulator type with vertical layout are split installation.
