  • The product description

    Energy storage tank type hydraulic control slow close check butterfly valve is our factory in digesting and absorbing foreign hydraulic control valve based on the latest development of new products. At present, the valve is the latest generation of hydraulic control butterfly valve in our country, it has both the function of the gate valve and check valve, is a kind of can according to the setting in advance good program, two stages (fast clearance Angle, and then slowly closed rest Angle) closed action to eliminate water hammer in pipeline damage their ideal control system.

    Structural characteristics of

    This product is mainly composed of butterfly valve body, transmission device, hydraulic and electrical control part of the group. Has the following main features:

    A. environmental protection products in the valve cavity through the water using harmless to human body health and safety and environmentally friendly coatings, in drinking water sanitation standard, the medium in pipeline doesn't create any pollution.

    B. conventional type product in the valve cavity through the water the adhesion of anticorrosion coatings. This valve seal form is divided into two kinds, the first form is: stainless steel, stainless steel, and USES the three eccentric structure of its sealing performance and reliable butterfly plate shut tight, easy to release; Seal adopt stainless steel, corrosion resistant wear long service life, convenient maintenance, after the valve with long steel rubber, it USES a leak, only need to replace the sealing ring; Bearing for lead-free no oil self-lubricating bearing has a carrying capacity is strong, good wear resistance, low friction resistance and other characteristics; Shaft end seal USES self-tightening type such as double seal, the sealing effect is good. Butterfly plate plastic adopts streamline design, small flow resistance coefficient (< 0.2), the valve strength, good rigidity, body strength test can withstand twice the nominal pressure. Has the characteristics of novelty, beautiful shape.

    This valve has a perfect hydraulic system and electric control system, as well as on-site operation, also can remote operation, but this valve control system USES the storage tank to replace the present domestic several valve factory in the production of hydraulic control butterfly valve with a heavy hammer hammer, hammer potential energy into hydraulic energy, not only save the long running bearing weight of energy consumption, improved the hydraulic pressure performance of the system to avoid the runtime maintenance personnel casualty accidents and mental insecurity and fear, and its control mechanism design is novel, reasonable design, small volume, light weight, simple structure, complete functions, movements flexible and reliable, beautiful appearance, energy saving material, convenient maintenance, and do not need to stop the pump when maintenance work and so on. To easily realize pump valve interlocking program control and microcomputer centralized control, power failure, shaking the manual oil pump can close the valve. The valve open and close, the movement is very convenient. This valve hydraulic and electric control parts be separated from the valve installed, according to whether the hydraulic and electrical separation and two kinds of forms, user can choose according to the situation.

    The working principle of

    Hydraulic system power supply electrical units, there are three kinds of oil pump accumulator hydraulic energy storage, manual oil pump, which stored in accumulator hydraulic can give priority to power supply, pump unit is responsible for the accumulator charging, when need can also direct drive valve switch, manual oil pump used in the accumulator, in the absence of any stored energy without electricity manual switch valve. To lose electric valve type hydraulic system, the two solenoid valve electromagnet to when the valve opens at the same time, the loss of electricity at the same time the valve closed. For electric valve type hydraulic system, an electromagnetic valve electromagnet electric valve opens, the other electromagnetic valve electromagnet closed electric valve. Open valve speed regulation by integrated block throttle valve; In two stages, automatically shut off the valve closed fast first is about 65 ℃, and then slowly closed left about 25 ℃, fast closing speed and Angle in the cylinder backend device regulation. In the case of without electricity or need to manually, by artificial push electromagnetic valve valve core, make the oil in the corresponding state, shaking the manual oil pump, can open or close the valve.

  • Storage and maintenance
    Products for a long time, should be placed in a dry place, closed at both ends of the import and export, in the sealing surface coated with anti rust oil. When the temporary parking can be added in the external wall plate auxiliary support to maintain a smooth. The first half is not installed, the hydraulic system for cleaning oil. This valve is prohibited open storage.
    Installation and maintenance
    Before installation should check the valve nameplate parameter meets the use requirements; cleaning the channel of the valve body and disc, check each part have no damage phenomenon and parts of the bolt is fastened. If the valve is installed in the outlet of the pump, the direction of the valve body to seal the direction of the pressure, and the direction of the water pump in the opposite direction; butterfly valve installed on the basis of the level should be corrected to ensure that the valve shaft does not tilt. Valve supporting feet and auxiliary support is mainly used to ensure the valve installation smooth operation, not a lot of bear perpendicular to the pipe axial water thrust; lifting may not flip, upside down; pay attention to the four lifting points to select the position of equilibrium.
